摘要

SF6电流互感器目前在500 k V以上电压等级变电站得到了广泛应用

一旦发生故障

将对电网的安全稳定运行造成很大影响。笔者介绍了2起TAG550型SF

电流互感器在雷雨天气下发生内部击穿故障

并把2台在运的该型号电流互感器更换后

进行返厂试验与解体检查。根据试验与解体检查情况

分析了该型号SF

电流互感器的故障原因并提出了应对措施。

Abstract

At present

current transformer has been used widely at 500 kV and above

which

in caseof fault

will cause great influence on the safe and stable operation of power grid. In this paper

the twointernal breakdown faults of TAG550 SF

current transformer under thunderstorm weather are introduced

after the replacement of the same type of current transformer in the two unit

the back to factory test

thedisassembly and inspection are carried out. The reason for the fault of the current transformer is analyzedand the corresponding measures are proposed in accordance with the test

disassembly and test situation.
