摘　　要：±500kV高压直流输电(HVDC)换流阀绝缘型式试验是目前国际上最高电压等级的换流阀绝缘试验。冲击试验是换流阀绝缘型式试验中的难点,对试验回路及设备的要求很高,试验难度很大。文章以三峡—上海直流输电工程用±500kVHVDC换流阀的完整四重阀试验为例,介绍了其结构、负荷特性,以及换流冲击试验和单阀冲击试验技术,并给出了部分试验结果。试验结果表明,该阀的内部参数设计满足技术要求。The valve insulation type test of ±500 kV HVDC power transmission is the test of highest voltage grade now on the world.The impact test is a difficult point in valve insulation type test, and the requirement for testing loop and equipment is very high. The paper introduced its struetural, load property, converter impact test and single valve impact test technology taken a complete quadruple valve test of Three Gorges - Shan ohai ± 500 kV HVDC power transmission as an example, and gave partial test result. The test result shows that the internal parameter design of this valve satisfies the technical requirements.
