摘　　要：应用于失超保护的旁路开关,为配合系统其他部件,以减小触头开距的方式来实现开关快速分闸及动作时间的一致性,这对开关的绝缘性能提出了更高的要求。本文通过原样机的介电性能试验和电场仿真发现了旁路开关触头处的薄弱点,然后提出优化改进方案,并利用仿真和试验验证了优化方案的可行性,以期为同类型的开关绝缘设计提供参考。In order to cooperate with other parts of the system,the bypass switch applied to the quench protection realizes the fast opening and the consistency of the action time by reducing the contact opening distance,which puts forward higher requirements for the insulation performance of the switch.Through the electric field simulation and dielectric performance test of the original machine,the weak points of the switch contact are found,and they are optimized and improved.The feasibility of the optimization scheme is verified in order to provide a reference for the insulation design of the same type of switch.
