产品介绍

产品简介:

GG-1A(F)固定式户内交流金属封闭开关设备适用于额定电压为3-10KV,额定频率为50Hz的三相交流单母线和单母线旁路系统中,作为接受和分配电能之用。开关设备符合GB/T11022高压开关设备和控制设备标准之用。开关设备内主开关根据用户需求可配用真空断路器和少油断路器。

产品型号及含义

闭锁方案:

1、GG-1A(F)固定式户内交流金属封闭开关设备是GG-1A型高压开关设备改进后的派生生产品,是在原GG-1A型高压开关设备上加装“防误”闭锁装置和完善的接地系统,以达到以下“五防”要求:

a、防止带负荷分、合隔离卡关;

b、防止误人事电间隔;

c、防止误分、合断路器;

d、防止带点挂接地线;

e、防止带地线合隔离开关。

2、开关设备的每一个线路方案均有两种“五防”闭锁方案,即一般闭锁方案和简易闭锁方案,以供用户选用。一般闭锁方案为设置单相或三相接地开关的方案,该方案带遮栏柜,可柜后装板门,也可靠安装,基本采用机械闭锁实现“五防”,必要时亦采用高压带电显示装置和程序锁。为满足广大用户需求,本公司既承接新柜生产,又可协助对老柜进行“无油化”改造(即用真空断路器替少油断路器)。
