一.概述

    GN30-12型旋轉式戶內高壓隔離開關是一種旋轉觸刀的新型隔離開關，主要結構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，通過旋轉觸刀，從而實現開關的分合閘。

       GN30-12D型開關是在GN30-12型開關基礎上增加帶接地刀的形式，可滿足不同電力系統的需要。本產品設計緊湊、占用空間小、絕緣能力強、易于安裝調整，其性能符合《交流高壓隔離開關和接地開關》的要求，適用于額定電壓10KV交流50HZ及以下戶內系統中，作為在有電壓無負載情況下，分合電路之用。可與高壓開關柜配套使用，也可單獨使用。

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 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.
