1. Introduction The catalogue presents RELF medium voltage switchgears:

- with air insulation, - metal clad, - compartment, withdrawable type, - with a single busbar system, - nominal voltage up to 24kV, - adapted for interior installation.

2. Switchgear description

The RELF switchgear is intended for switching stations of companies which generate, transmit and use electric power. It is compliant with standards (IEC) PN-EN 62271-200 and (IEC) PN-EN 62271-1, it provides a degree of protection up to IP54 for casing and IP2X for internal partitions, according to (IEC) PN-EN 60529. The switchgear is suitable for operation under normal conditions defined by the standard (IEC) PN-EN 62271-1 for interior distribution and control equipment. The switchgear was designed in such a way as to ensure safe normal operation, inspection and service.

The switchgear is a frameless structure made of riveted, hot-dip galvanized steel sheets. This is a multi-compartment cubicle whose walls and partitions form a self-supporting structure.

The switchgear cubicle is divided into compartments: connection compartment, busbars compartment, main device compartment (with a withdrawable unit) and auxiliary circuits compartment

Doors and side shields of the outermost panels (rear shields for the wall installation version) are covered, as a standard, with a powder coat of grey colour (RAL 7032) or another colour, upon the customer’s order.

. Types of fields The switchgear consists of panels with various functions. These are:

- incoming (supply) panel with a circuit breaker and voltage measurement, - outgoing (outlet) panel with a circuit breaker or contactor, - left / right coupling panel or rear cable connection, with a circuit breaker, - left / right coupling panel or rear cable connection, with a bridge, - measurement panel, with earthing of main busbars, - panel with a load-break switch.

The withdrawable unit may be equipped with a circuit-breaker, contactor, bridge,

set of transformers with fuses or block with fuses. It can assume the following positions: connected, test/disconnected and removed (beyond the panel).

Interlocks are used for the withdrawable unit with the circuit-breaker or contactor that make it possible to perform switching activities only in the connected and test/disconnected positions. Withdrawing or slipping the withdrawable unit to/from the operation position is possible only if the main connector is open. The main connector may only be closed if it is fed from the auxiliary circuits.


7

Switchgear characteristics:

- an air insulation, - hot galvanised sheet structure, riveted without welding, - Loss of Service Continuity Category – LSC2B (three compartments of the main circuit), - high level of operational safety, - IAC classification AFLR, - interlocking and protection against any improper connecting operation, - rear wall installation option (access only from the front side), - wide range of the main device and panel types, - possible to expand with more panels, - easy operation.

The switchgear ensures a high level of operational safety through:

- high resistance of the metal enclosure to internal arc impact, - interlocking of improper connecting operations or door opening, - handling the withdrawable unit with door closed, - use of compartments where partitions provide the IP2X protection level, - visual control possible with sight glasses, - signalling of voltage in the panels.

3. Switchgear construction Structure

The RELF switchgear panel is constructed as a cubicle with four separate functional compartments:

А - busbar compartment (main circuits), В - main device compartment (main circuits), С - connection compartment (main circuits), D - auxiliary circuits compartment (low voltage circuits).

The switchgear cubicle is a riveted steel structure of bent steel sheets, without welding. Its walls and partitions form a self-supporting structure. The cubicles are constructed of hot galvanised sheets 2 mm thick. The sheets are joined with steel flat head rivets of high strength.

The functional compartments are limited by internal partitions, vertical or horizontal. Internal partitions are fixed to side walls, which reinforces and stabilises the whole casing. Additionally, the external walls of the switchgear’s outermost panels have double side shields, screwed to them; the shields are made of painted 2 mm sheets.

The RELF switchgear may be manufactured as a free standing installation or for installation of the rear wall. In the case of the rear wall version, the rear door with interlocks are replaced with a screwed down shield.

The front strip between the main device compartment door and the connection compartment door, as well as the level partition between the two compartments, are both removable, which significantly facilitates maintenance.

The internal partitions provide safe access to the main devices compartment and connection compartment, even if the busbars are live.

According to the LSC (Loss of Service Continuity) category, the RELF switchgear is compliant with LSC2B. This condition is fulfilled by three-compartment switchgears when the withdrawable unit is in the off position.


10

Doors of the main circuit compartments are made of black painted 3 mm steel sheet. Doors are fitted with hinges and locks that are able to withstand explosion loads. The hinges allow for opening doors at 135. Side edges of doors are protected by lock bolts and hinges.

Top and bottom door edges are stiffened with stiffening sections, specially shaped and welded in.

The main device compartment door is fitted with an inspection hole for visual control

of the withdrawable unit position and connection activity. The door structure allows for mechanical switching off of the circuit breaker in the connected position, through the closed door. Vent flaps.

In the upper part of the main circuit compartments, there are openings of exhaust ventilation ducts, closed with flaps. Their task is to discharge the pressure created inside the compartment as a result of an internal arc fault.

A sudden increase of pressure inside the switchgear compartment breaks the plastic screws and opens vent flaps which may work with limit switches installed on the switchgear roof. The limit switches, controlled with the opening flaps, generate a pulse triggering the power circuit breaker. This limits the consequences of the short-circuit arc formed inside the cubicle compartment.

The withdrawable unit is a system comprising a running gear and depending on function comprising also: circuit breaker, contactor, a set of voltage transformers with fuses or a short-circuiting block. The running gear provides a mechanical connection between the withdrawable unit and the switchgear panel. Its stationary part is coupled with the panel by two-sided locking in the slideway notches.

The movable part of the running gear moves between the connected and test/disconnected position with a lead screw, hand-driven with a crank or motor drive, with the door closed. The connected position and the test/disconnected position are signaled by the position indicator once the unit gets into proper position.

Movable partitions in the main device compartment are presented as a part of the main

device compartment description. Distribution panel compartments

The busbars compartment is inaccessible during normal operation. For maintenance works, the busbars are accessible from the cubicle top, if the exhaust flaps are dismantled. The compartment is closed on both sides with bushing plates made of non-magnetic steel sheet. The plates protect the neighbouring panels in case an electric arc appears in the busbar compartment.

The bushing plates with bushing insulators are elements which support the busbars. Distribution busbars branch off from the main busbars and get into the support bushing insulators which separate the busbar compartment from the main device compartment.


11

The main device compartment is accessible after its door is opened in the interlock-controlled mode. The main device compartment contains the withdrawable unit, as well as all the elements necessary for its co-operation with the distribution panel, such as: slideways of the withdrawable unit, movable partitions, support bushing insulators with inter-compartment contacts built-in, elements of door interlocking and earthing switch interlocking, as well as control circuit sockets.

The non-magnetic steel plate which separates the main device compartment from the connection compartment and busbar compartment is fitted with support bushing insulators. Distribution busbars and inter-compartment contacts are set in the insulators.

The main device compartment is fitted with metal movable partitions with their actuating mechanism. They are to separate the compartment space from the stationary contacts, which may be live, when the withdrawable unit is in the test/disconnected position or removed position. After the withdrawable unit is shifted from the connected position to the test/disconnected position, they cover the support bushing insulator holes and close the access to the live inter-compartment contacts; the protection level remains compliant with IP2X. There is a safe insulation space between the contacts and the closed cover.

If the withdrawable unit shifts from the test/disconnected position to the connected position, the movable partitions draw aside and the stationary contacts are uncovered, which allows for connecting the circuit breaker contacts.

The sight glass allows for visual inspection of mechanical indicators of the circuit breaker state and the drive loading state.

The connection compartment is designed to connect cables or busbars and it is

accessible by opening the compartment door (the front one in the rear wall installation version and front and rear ones in the free standing version) in the interlocking controlled mode. This compartment is fitted with current transformers, earthing switches and (depending on the operational needs) optional: voltage transformers, earth-fault current transformer and surge arresters. The voltage transformers are installed in the front part of the connection compartment. The earthing switch is hand-operated. Its loading state is signalled with a position indicator.

The compartment bottom is closed with a sectional floor cover which is a cable channel plate at the same time. The plate holes are protected with rubber cable channels. The cables are fixed with cable clips set on brackets.

The auxiliary circuits compartment (low voltage compartment) is made as a control

cabinet and it is completely separated from the high voltage zone of the switchgear. The cabinet has its own metal casing and it is prefabricated independently from the power part of the switchgear. As it is assembled, it can be fitted with devices at a separate stand and only then fixed to the switchgear cubicle.

It is designed for the installation of: protection units, inspection, control and measurement apparatus, as well as automatic control elements.

The cabinet is installed on the switchgear roof, above the main device compartment. The cabinet bottom, as well as its rear and side walls, have many openings for cable and conductor channels. The holes are covered with plates that may be removed as needed. For apparatus installation, a perforated installation plate is designed on the rear wall of the cabinet. The apparatus may also be installed on side walls. The cabinet structure may be customised in agreement with the manufacturer.

Busbar system Main busbars

In the switchgear, there is a single three-phase busbar system with a triangular arrangement of phases. They run in a separate compartment. Copper flat busbars have been selected, with rounded edges, of the following intersections: - in the 12 kV switchgear: for 1250 A current 100х10 R5 mm for 1600 A current 2х(60х10 R5 mm) for 2500 A current 2х(100х10 R5 mm)

for 3150 A current 3х(100х10 R5 mm) for 4000 A current 4х(100х10 R5 mm)

- in the 17.5 kV switchgear: for 1250 A current 100х10 R5 mm for 1600 A current 2х(60х10 R5 mm) - in the 24 kV switchgear: for 1250 A current 100х10 R5 mm,

for 2500 A current 2х(100х10 R5 mm). The main busbars are supported by the distribution busbars running from the support

bushing insulators and by the bushing insulators installed in the side partitions. The distribution busbars are made of:

- copper flat busbars with rounded edges, of the following intersections: for 630 A current 40х10 R5 mm for 1250 A current 2х(40х10 R5 mm) for 1600 A current 2х(60х10 R5 mm) for 2000 A current 2х(80х10 R5 mm) for 2500 A current 2х(100х10 R5 mm) for 3150 A current 3х(100х10 R5 mm) for 4000 A current 4х(100х10 R5 mm)

Insulation elements

The switchgear has been equipped with insulators made of epoxide resins. In the connection compartment, busbars are supported by the supporting insulators.

For supporting busbars or channelling them between the switchgear panels, bushing insulators have been set in bushing plates of the panels' side walls.

The channel in the partition between the main device compartment and the busbar compartment and connection compartment is provided by the support bushing insulator. Three types of insulators are used, depending on the current and voltage. Earthing protection

There is an earthing conductor in each enclosure (a copper bus with 40x5mm or 40x10mm section) located at the bottom, on the back of the enclosure. These conductors between the enclosures are connected by bridges forming an earthing bus conductor. The bus conductor ends with terminals on the right and left hand side of the switchgear used to connect it to the facility’s earthing system. Connecting cables

The connection compartment is designed to lead one- or multi-core cables in plastic insulation. We recommend cable fittings manufactured by Tyco Electronics (Raychem), a company whose products we distribute.


13

Interlocking and protection against improper operations

The RELF switchgear is equipped with mechanical and electrical interlocking, compliant with the standard or additional requirements, to improve the safety of operation: Mechanical interlocks:

1) making it impossible to slide in or out the withdrawable unit into the connected position when the circuit-breaker is closed (required by the standard),

2) allowing the circuit-breaker to be opened or closed only in connected and test/disconnected positions (required by the standard),

3) allowing the earthing switch to be closed only in test/disconnected or removed position of the withdrawable unit,

4) not allowing the withdrawable unit to be shifted from the test/disconnected position into the connected position if the earthing switch is closed,

5) preventing the main device compartment door from opening if the withdrawable unit is in its connected or intermediate position,

6) preventing the cable compartment door from opening if the earthing switch is open, 7) allowing to change the position of movable element in the panel provided it is locked.

If the switchgear manufacturer agrees, it is possible to use additional key interlocks.

Electrical interlocks:

1) prevents the circuit breaker from tripping when the auxiliary circuits are not live; the circuit breaker may be tripped out only mechanically (required by the standard),

2) prevents the movable element from shifting to the connected position without feeding the control circuits,

3) prevents access to the earthing switch drive when closing the earthing switch is conditioned by additional factors (e.g. the busbar earthing switch can only be closed if the withdrawable units of a particular section are in the off position),

4) prevents access to the movable element drive if its shifting is conditioned by additional factors.

Interlocks, apart from those required by standards, are adjusted to each individual project. After obtaining the approval of the switchgear manufacturer the device may be fitted

with additional interlocks whose operation is based on miniature switches and electromagnetic locks.

The door structure makes it possible to unlock the door in an emergency and access the movable element drive in extraordinary situations.

4. Switchgear equipment Switching equipment

The switchgear may be equipped with vacuum circuit breakers VD4 (ABB), Evolis (Schneider), 3AH or SION (Siemens), NVL (Ormazabal), TM2C (Tavrida), VS1 (HEAG), gas-insulated circuit breakers HD4 (ABB), LF (Schneider) or contactors VSC (ABB). Other equipment may be used after obtaining the switchgear manufacturer’s consent.

As a standard, an EK6 (ABB) high-speed earthing switch is used, with a possibility to trip at short-circuit.

Measuring equipment Current and voltage transformers from ABB or other manufacturers are used

for measurement The voltage in panels is signalled with reactance insulators and a signalling cassette. Protection equipment

Low voltage equipment from any manufacturer may be built into the switchgear, according to the customer’s individual needs. It is possible to install any digital relay to protect the medium voltage circuits. There is a possibility to install the arc protection systems in the switchgear.

The suggested arc protection systems are ZŁ or VAMP. The systems sense if there is a short-circuit with their flash detection and current or voltage criterion inside the protected switchgear. If both events are simultaneous, the system is activated and a pulse is sent within a defined time (below 10 ms) releasing the main switch.

5. Main circuit and auxiliary circuit diagrams and switchgear automation, Main circuits

The structural diagrams of example main circuits are presented in Figure 2 and in the relevant catalogue sheets that can be found in this catalogue and on the website www.zpue.katowice.pl. The connection compartment has various equipment depending on the panel type.

Auxiliary circuits

The low voltage auxiliary circuits include: protection, measurement, control, automation control and signalling systems. The devices of these circuits are enclosed in the auxiliary circuit cabinet located above the main device compartment. The cabinet dimensions and example of device arrangement are presented in Figs. 3 & 4.

In order to obtain examples of internal and installation connection diagrams for main and auxiliary apparatus for typical switchgear equipment, please contact the switchgear manufacturer.

Switchgear automation

The switchgear is suitable for operation in an integrated control, display and data collection system. For this purpose, it is fitted with digital protection relays (with the possibility of digital communication) and with power engineering automation control units. The switchgear may then operate in superior and automatic control systems. 6. Switchgear packaging, transport and installation Packaging Three types of packaging are used for the RELF switchgear:

a) standard: the switchgear enclosure placed on a pallet is wrapped in air bubble film and then in stretch film,

b) crates: the switchgears packaged as above are placed in crates, c) especially for maritime transport: the switchgears with a moisture absorbing agent

placed inside are packed into bags made of film with preservation properties, from which air is sucked out. Switchgears preserved in this manner are transported on pallets or in crates.

Transport

As a standard, switchgear enclosures are transported individually. Switchgears may be transported to the room they are intended for and moved within that room using a crane, fork lift truck or on rollers.

The enclosure is f i t ted wi th transport grips for crane l i f t ing. The bend angle of fastening ropes should not exceed 120º. It is forbidden to fasten the ropes directly to the enclosure structure.

The enclosure is placed on a transport pallet in order to make transport with a fork lift truck possible.

During switchgear transport and placement caution should be exercised so as not to damage the coating and the protective sheet metal.

Principal equipment such as circuit-breakers, contactors and withdrawable units and low voltage equipment sensitive to shock are transported separately in original packaging supplied by the manufacturers.


16

Switchgear installation The switchgear foundation and the external cable and busbar connections depend on

the construction of the plant in which the switchgear is going to be placed. Erection should be performed taking into account the guidelines provided by the switchgear manufacturer.

The switchgears can be mounted: directly on the floor, on a foundation frame fixed to the floor or on the steel or concrete structure in the facility. Independently of the substrate, the switchgears have to be placed horizontally and fastened.

F igure 5 presents the location of the swi tchgear in a room The X dimension depends on the switchgear version:

- for the rear wall installation version, the gap must not be less than 100 mm, - for the 100 mm wide cubicles, full opening of the door is possible at X not less than 1000 mm. For the upper busbar lead, the cubicle is additionally fitted with a 400-550 mm deep

busbar channel located in the rear part. It is advised that dimension Y of the switchgear room should be at least 1000 mm greater

than the overall width of the switchgear due to installation technique. Advised minimal height (A) of switchgear room’s door for a switchgear with auxiliary circuit

cabinet 400 mm high is 2500 mm and for 600 mm high is 2700 mm. Figure 6 presents examples of floor openings dimensions for cable channels.

They are only approximate ones, their exact location should be arranged at switchgear ordering. Figure 7 presents the carrying/erection frame of the RELF switchgear, with openings

for the switchgear fixing to the ground. The way of fixing switchgears to the ground is present on Figure 8.

7. Equipment delivered with the switchgear The following equipment accompanies each switchgear:

- fasteners for connecting the transport sets, - crank for moving the withdrawable unit, - crank for the earthing switch drive, - the movable element trolley, - keys to the enclosure doors.

Documents delivered with the switchgear: - declaration of conformity, - switchgear operating manual, - operation and maintenance manuals and warranty cards for the equipment used, - switchgear as-built documentation, - warranty certificate.
