一.概述
GN30-12型旋轉(zhuǎn)式戶內(nèi)高壓隔離開關(guān)是一種旋轉(zhuǎn)觸刀的新型隔離開關(guān)，主要結(jié)構(gòu)式在三相共底價的上、下兩個平面上，固定兩組絕緣子及觸頭，通過旋轉(zhuǎn)觸刀，從而實現(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《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10KV交流50HZ及以下戶內(nèi)系統(tǒng)中，作為在有電壓無負(fù)載情況下，分合電路之用?？膳c高壓開關(guān)柜配套使用，也可單獨(dú)使用。

英文翻譯：
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 b 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 perbance 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 separaby.
