新型126kV高压真空断路器的设计及开断能力试验研究
Test on Novel Design and Breaking Capacity for 126 kV High Voltage Vacuum Circuit Breaker
摘要
Abstract
A novel design method for 126 kV high voltage vacuum breakers was presented based on the application of vacuum switch technology in 126 kV voltage class.The fundamental idea behind the proposed approach is to use double-breaks with novel distribution,so as to achieve voltage-sharing distribution in each break;thus the voltage-sharing capacitance is no longer needed in contrast with the traditional method.As a result,potential problems can be avoided.The breaker＇s moving system was designed with the novel structure,and optimized with the Virtual Prototyping technology of ADAMS.The synthetic test system was built up to test the breaking capacity of the breaker.A series of experiments verify that the breaker has the breaking capacity of 31.5 kA short-circuit current,demonstrating that the proposed scheme for designing the 126 kV high voltage vacuum breaker is not only feasible but also novel and effective.关键词
