摘　　要：江苏利港电厂泰北变电站到梅里的500 kV是国际上第一条同塔4回线输电线,介绍了该同塔4回线路真型塔的雷电冲击和操作冲击电压的试验过程,重点论述了用两台冲击电压发生器进行的试验方法、试验项目、试验结果,最后给出了真型塔各回路(对地、相间)雷电和操作波电压下的50%放电电压短尾波雷电等试验结论。The 500 kV lines from Ligang Power Plant to Meili are the first four-circuit lines on the same tower in the world. The lightning surge and switching surge tests performed for the lines were presented, including the test method, the content, and the results. Conclusions drawn from the tests were given, including that related to the 50-percent discharge voltages under the positive and negative switching pulse voltages respectively.
