摘要
从多年试验实践出发,探讨了变电站站内500 kV线路避雷器和电容式电压互感器不拆除高压引线进行试验的方法。该方法可大大减轻高压线路拆接线工作量,并获得准确可信的测试结果,对线路避雷器和电容式电压互感器的试验有积极的指导意义。
The paper discusses a test method for 500 kV transmission line arrestor and coupling capacitor voltage transformer in substations which without removing high voltage connecting lead,based on test practices for many years.The method can greatly relieve workload of removing and connecting HV line lead and obtain accurately credible testing results at the same time.And it is positive to test on line surge arrester and coupling capacitor voltage.
