All the mechanical parts of the mechanism

are integrated into individual opening

and closing modules. The modules are

universal to SecoVac embedded pole

vacuum circuit breaker series, regardless

of rating. The module design assures no

mechanical adjustment is required after

replacement. This offers the user shorter

lead-times and reduces operational and

maintenance costs.

Front panel

Front panel fits into a collar frame in the

equipment when the breaker is in the

service position. It provides a metal barrier

between the breaker compartment and

the secondary device compartment.

Clearly marked and easy-to-read

operating controls and indicators include

trip button, close button, open/close

Interlock system

For personnel safety, SecoVac 3.3kV-27kV

is designed with a number of mechanical

and electrical interlocks. For example,

breaker contacts must be open before

the breaker can be moved from test to

service position. A positive mechanical

stop is provided when the breaker

reaches the service or test/disconnect

positions. Mechanical rejection interlocks

are provided to permit only the insertion

of properly rated breakers into specific

compartments.

These and other necessary interlocks

provide a comprehensive safety system.

Furthermore, springs automatically

discharge when the breaker is withdrawn

from the service position and breakers

cannot be inserted in the closed position. Typical layout for vacuum circuit breaker

Generator Circuit Breaker and Generator Switchgear

Generator Faults

The fault conditions in the proximity of a

generator source are more demanding

than those in normal distribution circuits.

These special fault characteristics require

specifically designed and tested circuit

breakers.

The critical points to be considered are:

Generator Circuit Configuration

As a result of the circuit configuration, two

key unique fault current conditions are

encountered by generator circuit breakers

(figure 1)

System-source short-circuit current

The short circuit fed by the transformer

(point “a”, figure 1) on the generator side

leads to high thermal and mechanical

stresses on the vacuum interrupters

because the full energy of the power

system feeds the fault. To clear these

faults, Generator Circuit Breakers

are capable to interrupt not only the

symmetrical fault but also the higher

asymmetrical fault currents with a DC

component of up to 75%. This will be the

maximum short circuit current the breaker

needs to interrupt with peak making and

withstand capacity of 2.74 times the RMS

current

Generator-source short-circuit current

If there is a short circuit (point “b”, figure

1) the current is fed by the generator on

the transformer side. The fault currents,

while relatively smaller in magnitude, are

subject to a phenomenon called Delayed

Current Zero. This unique characteristic

is a result of the very high X/R ratio of the

circuit and the operating conditions of the

generator, which can combine to produce

a DC component of the fault current

exceeding 100%. The asymmetrical fault

current peak becomes so high and its

decay becomes so slow, that the current

zero can be delayed for several cycles.

Circuit Breaker High Voltage

a b

Fault at “a” Fault at “b”

Step-up Transformer

As vacuum interrupters rely on a current

zero to break the current, the delay it

results in longer arcing time with extreme

thermal stress on the interrupter.

The generator circuit breakers are tested

according to IEC/IEEE 62271-37-013 to

withstand the high electrical, thermal and

mechanical stress during the interruption

of fault currents with a DC component of

up to 130 %. Normally this short circuit

current will be 50% of system source

short circuit current with very high DC

component.

Unique Voltage Conditions

Generator circuits are typically designed

for high efficiency in order to minimize

the power loss of the system. Therefore,

the generator circuit breaker may be

located very close to both the generator

and transformer, connected by short

conductors with a large cross-section,

resulting in a very low resistance and low

stray capacitance. These characteristics

combine to produce very high natural

circuit frequencies resulting in extreme

Transient Recovery Voltages (TRV) with

high Rates of Rise of Recovery Voltage

(RRRV).

Very fast Rate of Rise of Recovery Voltage

(RRRV)

An important factor is how fast the TRV

rises across the recovering gap after

current zero. This is measured by the RRRV,

which is proportional to the peak value

of the transient voltage in kV, divided by

the time it takes the voltage to reach that

peak value in microseconds.

Values for standard Medium Voltage

distribution circuits are in the range of 0.4

to 1 kV /microsecond, while RRRV values

for generator circuits are about 3.5 kV /

microsecond.

These characteristics where tested for the

for the first time at the KEMA laboratories

in Netherlands using a Direct on Line

connection with GE’s SecoVac VB2+G

Generator Vacuum Circuit Breaker.

Out of phase switching

The out-of-phase voltage conditions can

occur during normal start-up when the

generator and power system voltages

are not in sync. Initially, the generator is

off and the generator circuit breaker is in

the open position with the power system

operating. The voltage across the open

circuit breaker contacts is equal to the

normal power system voltage. When

additional or emergency power is desired,

the generator is started and begins to

produce voltage. As the generator comes

up to speed, the generator output voltage

and frequency slowly increase. This causes

the voltage across the open contacts of

the circuit breaker to vary.

IEC/IEEE 62271-37-013 requires that the

generator circuit breaker can switch off

under out-of-phase conditions (out-of-

phase angle 90°) while the voltages across

the open contacts can be as high as twice

the rated line-to ground voltage of the

system.

Transient Recovery Voltages (TRV)

The circuit produces the peak value of

TRV, which is nearly double the line-to-

line system voltage, across the contacts

within microseconds following the current

zero. The Vacuum Interrupter must re-

establish dielectric strength across the

open contacts gap in order to withstand

this fast rising TRV. If the interrupter is

able to withstand that voltage, then the

interruption is successful.

SecoVac VB2+G

Performance requirements for Generator

Circuit Breakers are specified in the IEC/

IEEE 62271-37-013 standard. This is a

combined standard intended to replace

the IEEE C37.013 and fill the gap of the IEC

which has never had a generator breaker

standard previously.

The new SecoVac VB2+G 15kV have

passed all the Type Tests as per the new

IEC/IEEE combined standard, becoming

the first Generator Circuit Breaker of the

SecoVac family.

The standard SecoVac VB2+ breaker and

the SecoVac VB2+G generator circuit

breaker can be used in all SecoGear

IEC switchgear panels. With the same

functionality and footprint of conventional

IEC Switchgear while getting all the

benefits from a fully proven Generator

Circuit Breaker.

SecoVac VB2+G can also be installed in

SecoBloc modules, producing the perfect

combination for OEM manufacturers

building generator switchboards.

Applications

A properly protected generator unit

increases its levels of reliability, availability

and safety, and by extension the same

for the complete electrical system where

is being operated. Even the smaller

generator units can produce high DC

component or Transient Overvoltage

levels requiring special breakers intended

to protect such fault conditions.

With this new addition to the SecoVac

family, SecoGear is perfectly set to

protect Generators. Applications up to

60MVA, 31.5kA, 15kV can be operated

with SecoVac VB2+G. These power output

ranges are commonly used on:

● Distributed Power Generation

-Diesel/Gas Engines

-Small Frame Gas Turbines

-Aero Derivative Turbines

● Marine Diesel-Electric Generators

● Oil and Gas Start-up/Back-up

Generator units

● Mining Power Plants

● Small Hydro

● Small Steam Turbines

Benefits

The SecoVac VB2+G generator circuit

breaker is based upon the same design

principles as our distribution type

SecoVacVB2+ breaker this results in

advantages for electrical designers,

operating personnel and maintenance

staff .

The SecoVac VB2+G is designed to

be fitted into GE’s SecoGear range of

medium voltage type tested IEC panels.

The SecoGear range can accommodate

generator, distribution circuit breakers

and fuse contactors within the same

standard panel design offering industry

leading safety, reliability and performance

features to meet the requirements for

all Medium Voltage Distribution in Power

Plant applications.

In addition to being able to be supplied

as part of a complete switchgear lineup,

SecoVac VB2+G can be supplied as part of

GEs SecoBloc OEM modules. SecoBloc is

designed specifically to allow OEM panel

builders to incorporate a type tested

circuit breaker and cable compartment

into their customer built switchboard

arrangement. VB2+G modules are

available in various configurations to suit

specific generator applications.

IEC/IEEE 62271-37-013 Combined Standard

Up until the development of a common

IEC / IEEE standard for generator circuit

breakers there was no IEC standard to

cover the special needs of circuit breakers

being used in generator application.

Commonly users were referring to the IEEE

standard for generator application.

History

The IEC proposed to have a standard

covering the generator circuit breakers in

November 2008, and started activities to

develop it after approval of the proposal in

April 2009.

Firstly the Standard was named IEC

62271-112, and later on moved to IEC

62271-37-013 and target of the project

broaden to jointly revise IEEE Std C37.013

with IEEE under the IEC/IEEE Dual Logo

-Joint Development Agreement- Liaison

with IEEE Switchgear Committee.

The document is pending to be officially

released in the first months of 2015 with

the official title: IEC/IEEE 62271-37-013

Ed. 1.0 High-voltage switchgear and

Controlgear - Part 37-013: Alternating

current generator circuit-breakers

Improvements to IEEE C37.013

The new IEC/IEEE dual standard has

several improvements compared to the

previous IEEE standard.

● It has included the definition of several

concepts in Clause 3.1, helping both

IEEE and IEC users of this document to

have same understanding of terms as

they are used in this document readily

available

● Included explanations of why certain

requirements are needed in generator

circuit-breaker applications that may

not be needed for standard distribution

circuit-breakers page 13

● The clauses covering generator-source

fault current requirements have been

greatly expanded in section 8.103.5.3

to explain how to treat the extremely

high degrees of asymmetry that may

occur under certain conditions

● Expanded the application section,

clause 8, in order to make the selection

of a generator circuit-breaker easier for

users, will enable the user to be sure

he has chosen the right circuit-breaker

to protect their particular generator

circuit

SubSea applications

SecoVac VB2 Plus 27kV has successfully

passed strict tests for SubSea applications,

proving its robustness, and versatility for

operation under severe conditions.

Extreme Temperature Testing

● Storage

ISO 13628-6: 2006, Clause 5.4.2.4.

The breaker is held inside an

environmental chamber in open

condition for 16 hours at -30ºC,

then the temperature is returned to

ambient temperature and the breaker

is operated with CLOSE / OPEN

operations carried out 5 times at

minimum control voltage, rated control

voltage and maximum and control

voltage

● Low temperature test

IEC 62271-100 Clause 6.101.3 -18ºC for

48 hrs.

The breaker is held in the closed

position at -18ºC for 24h. Then the

breaker is operated with CLOSE / OPEN

operations carried out 5 times at -18ºC,

at rated control supply voltage.

● High Temperature test

IEC 62271-100 Clause 6.101.3, +70ºC

for 48 hrs.

The high temperature test is to be

performed immediately after low

temperature test.

The breaker is held in the closed

position at +70ºC for 24h. Then the

breaker is operated with CLOSE /

OPEN operations carried out 5 times at

+70ºC, at rated control supply voltage.

Extreme vibration testing

Vibration tests were conducted in 3 steps.

Embedded Pole Design

SecoVAC fuse contactor applies the

embedded-pole design in the main

circuitry. The vacuum interrupter (VI) and

the main conductor are fully casted by

epoxy resin using APG process. So the

surface of the VI is not affected by the

environment condition, and the external

insulation is free from dust, humidity, due,

animal and filth. Therefore, the embedded

pole of SecoVAC FC is free of maintenance

in the whole life cycle operation. Likewise,

the fuse base uses the same APG process

of epoxy resin casting, improving the

insulation performance of the fuses and

the holders.

Fuse Selection

The fuse contactor unit uses fuse to make

and break the short circuit current and the

vacuum contactor to make and break the

overcurrent or the normal load current.

Therefore, it’s critical to choose a right

fuse to take over a reliable protection.

For the fuse selection, please refer to

IEC 60282-1 High-voltage fuses – Part 1:

Current-limiting fuses. The customer can

also refer to the following selection rules.

Just in case, you’re welcomed to contact

us or the fuse manufacturer.

The fuse manufacturer shall supply the

sufficient fuse data for the fuse selection,

including but not limiting to,

● Fuse classes: for the fuse contactor

application, the back-up current-

limiting fuse is recommended.

● Applied fuse standard: IEC 60282-1 /

VDE 0670 Part 4 High-voltage fuses

part 1: current limiting fuses and

DIN 43625 High-voltage fuses, rated

voltages 3.6 up to 36kV

● Fuse rated voltage: the rated fuse

Mechanical Life

Different from the VCB, the vacuum

contactor uses electromagnetic

mechanism and low chopping current

VI, so it has much longer mechanical life

which can reach one million operation

cycles, capable of frequent switching on/

off.

Technical data

Fuse Contactor

voltage shall be equal or a little bigger

than the rated system voltage

● Fuse rated current: the continuous

carry current without exceeding the

● Fuse dimension: in line with the referred

IEC/DIN standard and the following

chart

● Time-current characteristic of the

fuse: the curves shall show the relation

between the virtual pre-arcing time

and the prospective current; the time

range for back-up fuses from 0.01s to

600s, a dotted line shall be plotted from

minimum breaking current to 600s if

the minimum breaking corresponds to

a time less than 600s.

● Cut-off characteristic: the smaller of the

maximum cut-off current, the better of

the fuse

ANSI Device Numbers & Functions

These records are stored in non volatile

memory. Therefore, there is no need

for internal battery monitoring or

maintenance.

Trip circuit monitoring

Multilin 650 units offer as an option two

complete supervision circuits for breaker

trip and closing coils and circuits. These

supervision inputs monitor both the

battery voltage level and the continuity of

the trip and/or closing circuits, applying

current through those circuits and

checking that it flows properly. In order

to apply this feature it is necessary to

choose I/O board 1 option 2.

CommunicationsMultilin 650 units incorporate up to

three ports that operate independently.

Redundant ports are available for high

reliability applications:

Available protocols for rear port 1 and 2

are ModBus RTU, IEC 103 and serial DNP

3.0.

The third port is located in a removable

communications card. This plug-and-

play card can be easily changed in the

future as new standards arrive to the

market, thus providing a migration path

to the customer.

The protocol available for the third port

is DNP 3.0 over TCP/IP, UDP/IP, ModBus

TCP/IP and IEC 60870-5-104.

Working Principle

Working Principle of Operating Mechanism

The vacuum gas pressure inside vacuum interrupter is less than

1.33×10-3Pa. Under normal circuit conditions the interrupter is

closed. Arcing is established within the interrupter by withdrawing

the moving contact from stationary contact. This arc burns in

the metal vapor evaporated from local hot spots on the contact

surfaces. The metal vapor continually leaves the inter-contact

region and recondenses on the contact surfaces and surrounding

metal vapor condensation shield. The latter is usually isolated

from both contacts and serves to protect the glass or ceramic

envelope from vapor deposition. At current zero, vapor production

ceases and the original vacuum condition is rapidly approached.

The dielectric strength of the interrupter also increases, and the

circuit is interrupted. Within the contacts in the open position, the

circuit voltage is withstood internally by the inter-contact gap

and externally by the insulating envelope.

The energy that is necessary for closing the circuit breaker is

provided by the closing spring. The energy storage can be done

by the motor or by the manual charging handle.

Motor spring charging

The energy charging mechanism consists of energy storing

motor, gear wheel, cam, holder and closing spring. When the

energy-storing motor (11) is charged, the pinion of output shaft

(12) that is connected to motor will rotateand drive the gear

wheel. The holder fixed on the gear wheel will make the cam fixed

on the shaft move, which then drive the shaft to rotate, so that

draws out the closing spring (17) for storing energy. When the

block on the gear wheel is pushed away, the clutch is separated

and the holder (4) will hold the roller on the cam (5) to keep the

mechanism in charged position, thus completing the charging

operation succeeds.

When energy is charged manually, the operator charges

the spring by operating the energy-charging handle on the

mechanism up and down repeatedly.

When the charging operation is completed, you can hear a 'click',

and the energy charging indicator (13) is switched over, as well as

the status of position switch (6), cutting the secondary charging

circuit supply to motor. The operating mechanism now is ready

for the next operation. (Figure 3)

When the closing circuit is powered, the closing coil is energized

and the holder (4) will rotate counter clockwise to break away

from the roller on the cam (5). The cam, under the action of the

force from closing spring (17), will rotate clockwise,

to push the roller on the main shaft, which will move the main

shaft (10) in counter clockwise rotation. The main shaft moves the

connecting rod down through arm, so that the insulating rod (2)

moves upright, pushing the movable contact to the fixed contact

at the required speed, and compressing the contact spring and

making it a necessary contact travel (overtravel) to ensure the

pressure is generated between movable and fixed contacts.

After the closed operation is finished, the closed/opening indicator

(9) will indicate 'closed'. The power to the closing circuit will be cut

off. If the external power supply is energized, the charging circuit

motor will operate and the charging operation will be finished

automatically.

Note: Once the circuit breaker is in closed position, the closing operation will be prohibited.

Anti-pumping function is fitted with SecoVac to prevent repeated

sequences of opening and closing operations. Once the circuit

breaker is in closed position, the closing operation will be

prohibited.

When the circuit breaker is closed, the mechanism can be

charged for close, so that the circuit breaker can reclose

immediately after tripping.

When the breaker receives an opening command (the opening

push button is pressed or the tripping coil (16) is energized), the

tripping shaft will rotate clockwise. Under the action of opening

spring (3) and contact-compressing spring, main shaft will move

clockwise, and the insulating rod (2) will make the movable

contact to separate from the fixed contact at a suitable speed.

The buffer will absorb the residual energy and tripping operation

is completed.

After the tripping operation is finished, the closing/opening

indicator (9) will indicate 'open'. Meanwhile, the counter will record

the operation.

The follow interlocking facilities are

incorporated to ensure the safe operation

of the breaker. when the breaker is closed,

the withdrawable circuit breaker cannot

be racked between the service position

and test position.

● When the earthing switch is in the

closed position, the withdrawable

circuit breaker cannot be racked into

the service position

● When the withdrawable circuit breaker

is in service position, the earthing

switch cannot be closed

Correct installation is of primary

importance, the manufacturer’s

instructions must be carefully studied

and followed. It is good practice to use

gloves for handling the breaker during the

installation.

Please carry out installation and wiring

of breaker according to manual. Do not

place any foreign objects in the breaker or

modify it in anyway.

Check before installation

After the breaker is unpacked, check

the poles for any signs of mechanical

damage. The product nameplate and

quality certificate shall conform to the

order. Check goods according with the

packing list.

Clean the insulating parts with a clean

dry cloth. Make sure the upper and lower

contact arms are clean and free of any

deformation caused by mishandling

during transport or storage.

Check the vacuum pressure in the vacuum

interrupter through power frequency

withstand voltage test. If it fails, please

contact or your local GE office.

Interlocks Installation

Installation for fixed circuit breakers

● The careful and professional

installation is a fundamental condition

for the failure free operation of the

circuit breaker

● The circuit breaker should be

installed so that there are no external

forces applied to it from busbars or

mechanical supports

● The busbar connection should not

cause any deformation to the breaker

terminals

● Take note of supplied drawings for bolt

sizing and lengths

● Use the standard bolts with strength

of class 8.8 and the disc springs to

tighten the bus bar (Table 1)
