摘要

以聚四氟乙烯有机复合材料为主绝缘的新型干式高压产品

包括电流互感器、穿墙套管、电缆终端等

在电力系统已经应用多年

因为其不充油、不充气、无瓷、维护工作简便、耐污秽能力强、重量轻等鲜明特点

受到用户的热烈欢迎。但对该系列干式产品最主要的特点

以聚四氟乙烯薄膜为主的有机复合主绝缘材料

却缺乏相应的研究。笔者对该有机复合绝缘材料的电气寿命进行了研究

结果显示以聚四氟乙烯为主的有机复合绝缘材料

即使在设计场强3kV/mm下且考虑一倍的安全裕度

其寿命也可以达到45年以上

是值得信任的主绝缘材料。

Abstract

New dry-type HV power apparatus with insulate materials of PTFE film and others

such as current transformer

wall bushing

cable terminal

used for more than 20 years. For its outstanding characteristics of no oil-filling

no gas-filling

no porcelain

easy to maintain

strong anti-pollution

those products have been accepted generally. But too little research was done about its insulating materials made up of PTFE film and others. The result show the electric life of this material of PTFE and others could be more than 45 years even in 3 kV/mm and 100% safety margin.
