3、 原理与结构

Principle and Structure

GW8-126中性点、GW8-72.5电动隔离开关（外形见图1）由底座，支柱绝缘子和导电部分组成，在绝缘支柱的上方装有静触头和联接母线的接线板，在支柱绝缘子和绝缘支柱之间有底座、动触头、操作拐臂、操作绝缘子，操作机构通过连杆、操作绝缘子、操作拐臂与动触头相连。

GW8 type neutral point disconnecting switch (shape see Fig.1) mainly consists of base, insulators and electric conduction part, on the insulating support fitted with static contact and wir?ing board which connect generatrix. Between support insulator and Support Insulator, there are base, moving contact, operating turn arm and operating insulator. operating mechanism and moving contact are joined b?y connecting ?rod, ope?rating ins?ulator and operating turn arm.
