摘　　要：介绍了在换流阀合成试验回路升级改造中,为满足开关阀的耐压升高一倍,占地空间不变且能适当降低成本的要求。在新开关阀的结构设计中,通过在组件中应用反并联晶闸管堆、公用RC回路、蓄电池、冲击均压电容、电抗器和结构支撑件,并进行结构优化,解决了组件中的机械应力集中、电磁干扰、均压、局放、防火及电解电流等方面的问题,实现了技术上的创新,设计出满足要求的新开关阀。The mechanical design innovation of bidirectional on-off valve in the up-grade project of synthetic test circuit for convert valve is introduced. In order to increase voltage,not change in size and decrease cost, the structure design of the new on-off valve, anti-parallel thyristor stack is used, RC circuit, storage battery, impact capacitor, reactor and support parts are shared, at the same time, the structure for solving stress collect,electromagnetism disturb,vohage distribution, partial discharge,preventing fire and electrolytic current are optimized. The design of the new on-off valve satisfied with requirement is completed and the technology innovation is achieved.
