GN30-12KV户内旋转式隔离开关带单相接地

概述

     GN30-12型旋转式户内高压开关是一种旋转触刀式的新型隔离开关，主要结构是在三相共底架的上、下两个平面上，固定两组绝缘子及触头，通过旋转触刀，从而实现开关的分合闸。

    GN30-12D型开关是在GN30-12型开关基础上增加带接地刀的形式，可满足不同电力系统的需要。本产品设计紧凑、占用空间小、绝缘能力强、易于安装调整，其性能符合GB1985－89《交流高压隔离开关和接地开关》的要求，适用于额定电压10千伏交流50Hz及以下户内电力系统中，作为在有电压无负载情况下，分合电路之用。既可与高压开关柜配套使用，也可单独使用。GN30-12KV户内旋转式隔离开关带单相接地

Summary

GN30-12 rotary indoor high voltage switch is a new type of isolation switch with revolving contactor. Its main structure is to fix two groups of insulators and contacts on the upper and lower planes of three-phase common chassis. By revolving contactor, the switch can be switched on and off.

GN30-12D switch is based on GN30-12 switch with grounding knife, which can meet the needs of different power systems. This product is compact in design, occupies small space, has strong insulation ability and is easy to install and adjust. Its performance meets the requirements of GB1985-89 "AC High Voltage Isolation Switch and Grounding Switch". It is suitable for indoor power system with rated voltage of 10 KV AC 50 Hz and below, and can be used for dividing and closing circuits under the condition of voltage and no load. It can be used with high voltage switchgear or separately.
