摘　　要：宁东—山东±660kV直流输电工程是世界上第1个采用 660kV电压等级的直流工程,该工程采用单12脉动换流阀结构,单阀跨接电压高,阀塔尺寸较大,对换流阀试验提出了极高的要求。文章对换流阀绝缘试验项目和实际试验参数进行全面介绍,并对绝缘试验中遇到的难点以及解决方案进行了重点阐述。The Ningdong-Shandong ±660 kV HVDC transmission project is the first worldwide DC power transmission project in 660 kV voltage grade,where the single 12-pulse converter bridge is used resulting in the highest single valve volage and the largest valve tower dimension.Therefore,it is difficult for valve testing.In this paper,the items and parameters for the insulation test of valves are introduced,and the difficulties encountered during the test as well as the coutermeasures employed are illustrated.
