摘　　要：±800 kV直流输电是目前世界上直流输电领域电压等级最高的输电方式。±800 kV特高压直流换流阀是特高压直流输电(UHVDC)中的关键设备,在投入电网使用之前必须要进行严格的型式试验。单阀交流耐压试验,是特高压直流换流阀绝缘型式试验中一个比较特殊的试验项目。笔者以国内自主试验的首例±800 kV换流阀绝缘型式试验为例,介绍了±800 kV换流阀相关电气结构,并对单阀交流试验的加压方法进行了研究。± 800 kV DC transmission is a current transmission approach of the world＇s highest level in the area of the direct current transmission system. ±800 kV HVDC thyristor valve is the key equipment in Ultra-High Voltage DC （UHVDC） transmission. It must be taken rigorously type test before put into operation. AC voltage test of single valve is a special test item in the valve dielectric tests. In this paper, taking the first domestic independent testing, ± 800 kV thyristor valve dielectric test, as an example, introduces the associated electrical structure, and studies the test methods on single valve＇s AC voltage test.
