35kV倒置式电流互感器渗油分析及处理

Analysis and Treatment on Leakage Oil of 35 kV Inverted Current Transformer

介绍一起35kV倒置式电流互感器渗油故障,分析认为金属膨胀器顶部阀芯密封胶垫老化、破损是渗油的直接原因,提出一种电流互感器不放油直接更换膨胀器密封胶垫的方法。

This paper analyzes the fault of the 35 kV inverted current transformer oil leakage, analysis the metal expander sealant pad at the top of the valve core aging, damage is the direct reason of oil leakage, proposes a method that repaces metal expander sealing rubber gasket directly of current transformer without oil drain.
