概述

     GN30-12型旋轉(zhuǎn)式戶內(nèi)高壓開關(guān)是一種旋轉(zhuǎn)觸刀式的新型隔離開關(guān)，主要結(jié)構(gòu)是在三相共底架的上、下兩個(gè)平面上，固定兩組絕緣子及觸頭，通過旋轉(zhuǎn)觸刀，從而實(shí)現(xiàn)開關(guān)的分合閘。

    GN30-12D型開關(guān)是在GN30-12型開關(guān)基礎(chǔ)上增加帶接地刀的形式，可滿足不同電力系統(tǒng)的需要。本產(chǎn)品設(shè)計(jì)緊湊、占用空間小、絕緣能力強(qiáng)、易于安裝調(diào)整，其性能符合GB1985－89《交流高壓隔離開關(guān)和接地開關(guān)》的要求，適用于額定電壓10千伏交流50Hz及以下戶內(nèi)電力系統(tǒng)中，作為在有電壓無負(fù)載情況下，分合電路之用。既可與高壓開關(guān)柜配套使用，也可單獨(dú)使用。GN30-12KV戶內(nèi)旋轉(zhuǎn)式隔離開關(guān)帶單相接地

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.
