一.概述

    GN30-12型旋转式户内高压隔离开关是一种旋转触刀的新型隔离开关，主要结构式在三相共底价的上、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《交流高压隔离开关和接地开关》的要求，适用于额定电压10KV交流50HZ及以下户内系统中，作为在有电压无负载情况下，分合电路之用。可与高压开关柜配套使用，也可单独使用。

英文翻译：
A. Overview

GN30-12 type rotary indoor hv isolating switch is a new type of rotating knife touch isolating switch, mainly in three phases of the reserve price were structured, make two plane, fixed two groups of insulator and contacts, through the rotating touch the sword, so as to realize the points off switch.

GN30-12 D switch is in GN30-12 switch basis with grounding in the form of increased sword, can meet the needs of different power systems. This product design compact, take up the space is little, insulating ability strong, easy to install, its performance meet the high pressure isolating switch and exchange grounding switch "requirement, rated voltage 10 KV ac frequency 50 HZ and the following indoor system, as in a voltage no-load condition, and the use of circuit points. But high-voltage switchgear and supporting the use, and also can be used separately.
