摘要
针对±800 kV换流阀多重阀绝缘试验因试验回路尺寸大、试验电压高等造成试验实施难度很大的问题,笔者通过采用等效模拟负载模拟部分阀段,试验研究了±800 kV换流阀多重阀的直流电压试验技术、雷电冲击试验技术、操作冲击试验技术。研究表明,此种试验方法是可行的。
For the dielectric tests of ±800 kV thyristor valves, the test of MVU is very difficult to perform due to the large size test circuit and high test voltage etc.. By using equivalent simulation load to replace parts of thyristor valves, the test techniques is studied for the MVU of ±800 kV thyristor valves, including DC test, lightning impulse test and switching impulse test. The results show that such method is practicable.
