摘要

通过对两起国产12 kV铠装式金属封闭开关设备烧毁故障原因的分析和总结

指出目前运行的许多国产12 kV铠装式金属封闭开关设备存在结构性弱点

容易在天气骤变过程中出现凝露

发生绝缘闪络故障和扩大事故范围

并明确提出了解决对策和建议。同时建议制造企业和电力用户重视早期国产12 kV铠装式金属封闭开关设备的整改问题

以达到控制绝缘故障和杜绝“火烧连营”事故的发生。

Abstract

This paper analyzed the fault reason of two domestic 12 kV metalclad switchgears’ burn out

pointed out the structure shortcomings of domestic 12 kV enclosed switchgears in service.Easy produce vapor condensation when weather sudden change

lead to insulation flashover fault and enlarge accident range.The countermeasures were proposed

and manufacture factory and power user were suggested to pay attention to rectification of switchgears in early stage

so as to control even eliminate insulation fault.
