High-current- and generator circuit breaker switchgear

Answers for infrastructure.

High-current- and generator circuit breaker switchgear from Siemens – your benefits

Experience and customer orientationAs a pioneer in development of vacuum switchgear technology for reliable transmission and distribution of electrical power in medium voltage, Siemens has the competence and solutions for the unique switching duties of generator circuits.

In order to serve the high demands of the merging market for power generation sets in the range of 30 MVA at 10.5 kV up to 200 MVA at 18 kV, Siemens has optimized its portfolio of high current and generator circuit breaker switchgear.

The result is a range of switchgear types which are versa-tile in terms of functionality, installation and connection.

3AH38 / 37 vacuum generator circuit breaker n Type tested according IEEE standard C37.013 n High DC-components > 65 % n Maintenance free for 10,000 operating cycles n MTTF (mean time to failure) of 40,000 years

Proof of suitability for the switching application n Computer aided calculation and simulation of short time withstand and peak current under consideration of IEC 60909

n Dimensioning of enclosure and current path to with-stand dynamic and thermal impact of continuous and short circuit currents

n Verification of breaker interruption capabilities under consideration of delayed current zero

Personnel safety and reliability n Design and construction according IEC 62271-1 and IEC 61936-1, type tests according IEC 62271-200

n Internal arc classification (IAC) is available for enclosures of switchgear types HB1 and VB1

n All switching devices to be visually inspected and operated with all doors and covers in closed position.

n No explosion in the unlikely event of a fault in the vacuum interrupter of generator circuit breaker type 3AH38 / 37
