高压隔离开关过热缺陷分析及防范措施

Causes Analysis on High-voltage Disconnecting Switch Overheating Defects and Preventive Measures

介绍高压隔离开关过热缺陷的判断依据,以及河北省南部电网高压隔离开关的过热缺陷情况,分析缺陷发生的原因,认为其主要原因是老旧隔离开关设计结构不合理、元件质量不良、现场安装工艺不良和运行维护不当,提出隔离开关过热缺陷的反事故措施。

According to overheating defects of high-voltage disconnecting switch,the causes for defects have been analyzed,and the main reason is that the design structure not reasonable of old disconnecting switch,the bad component quality,the badly spot install craft and the not appropriate of maintenance.Combined with application in the Hebei south network of disconnecting switch,the analysis of typical defects and the processing methods have been discussed,and the preventive measures have been proposed.
