产品介绍

产品简介:

CRCGIS型气体绝缘式金属封闭开关设备(以下简称充气式环网柜)是以低压力SF6气体作为绝缘和开断介质的50Hz三相交流户内高压配电设备。环网柜密封箱体内分别装有负荷开关、负荷开关+限流熔断器、断路器等基本开关元件,利用负荷开关控制回路、开合负荷电流、过载电流;利用负荷开关+限流熔断器控制、开合、隔离变压器及其配送回路,对中压变压器的中压侧、变压器及低压配电回路内的短路电流及过载电流进行保护,利用断路器对设备或线路进行保护。利用基本单元可以做成共箱式柜或基本单元拓展成为多种配电系统方案。共箱最多可以为六共箱,拓展型式可以无限拼接。可以根据一次主接线,将CRCGIS-12 (F) 、  CRCGIS-12 (R)、 CRCGIS-12 (V) 气体绝缘式金属封闭开关设备进行组合,然后并柜使用,构成环网供电回路。断路器柜、负荷开关柜、组合电器柜也可分别单独使用。主要用于12kV及以下的二次配电系统,适用12kV供电线路的环网供电或双辐射供电,当某段线路发生故障时,经线路重组后使故障段隔离,可及时恢复健全线路的供电,大大提高了供电的可靠性和利用率。适用于电缆馈电网络的工商业区或农村乡镇的供电负荷大密度高的地区。使用安全、不受气候影响、安装容易、维修少,节省地方,很适合装于箱式变电站中。

产品特点:

1.小型化、全封闭、全绝缘、防凝露、抗污秽、高绝缘

2.寿命长:负荷开关10000次,断路器20000次。

3.适合高海拔:4000米

4。适合低温度:-45度

5.容量大:断路器柜额定电流1250A,开断电流31.5KA
