Breaking Capacity Test of 126kV/2500A/40kA Double Breaks Vacuum Circuit Breaker

초록

영어

High-voltage vacuum circuit breakers are intended for breaking the short-circuit current, and the breaking capacity is the major performance indicator. In the paper, the Weil synthetic circuit was built, and by using unit testing method and referring to standard GB/T 1984-2014, the breaking capacity of 126kV/2500A/40kA double-break vacuum circuit breaker developed by Central Research Institute of Tianjin Benefo Machinery Equipment Group Co., LTD was tested. Result showed that this vacuum circuit break can meet the breaking capacity requirement for grid integration
