摘要
隔离开关是发电厂和变电站中使用最多的一种高压开关电器。本文根据GN30-12型户内高压隔离开关的结构特点，分析了该型号隔离开关在合闸状态下动静触头的受力情况，在电接触理论基础上，研究了触指弹簧压缩量对GN30-12隔离开关接触电阻的影响，对隔离开关的安装调试以及隔离开关触指弹簧的选型具有一定的指导意义。
Disconnector is used in power plants and substations up to a H.V. switching equipment. In this paper ,the forces of the disconnector contacts in the closing state movement are analyzes based on the structural characteristics of the GN30-12 indoor H.V. disconnector,and the effects of contact compression spring on GN30-12 disconnector contact resistance is researched based on the theory of electrical contact for dealing with disconnector instal ation.
