摘　　要：随着高压变频器技术的发展,其晶闸管阀等效负荷试验的应用越来越多。等效负荷试验电路的应用显著地降低了运行试验所需的设备容量,但其试验等价性是一个值得讨论的问题。等效负荷试验电路的等价性的核心在于其是否正确再现作用在晶闸管阀的负荷。工程应用证明所设计的试验回路具有较好的试验等价性。In recent years, equivalent test circuit of thyristor valves has a widely application, with the development of t-IV inverter technology. The application of some equivalent test circuits significantly reduces the size of test facilities, hut the test equivalence of those test circuits is worth to he discussed. The core of some equivalent test circuits is whether it can reproduce the stress applied on the valves correctly. The application of this equivalent test circuit verifies that test circuit is more accurate.
