产品介绍

适用范围及特点

CRQ1M自动电源切换开关(以下简称切换开关)适用于交流50Hz额定工作电压380V、额定工作 电流63-225A双电源供电系统,用自动或手动操作方式完成常用电源与备用电源之间的切换。该切换开关主要用于医院、商店、银行、化工、冶金、高层建筑、军事设施等重要场合

1、安装的海拔高度不应超过2000米。

2、周围环境温度上限不高于+40℃,下限不限不于-524小时平均值不超过+35

3、大气的相对湿度在周围空气温度为+40时不超过50%?,在较低的温度下,可以有较高的湿度,应考虑到温度变化会发生产品表面的凝露。

4、无爆炸危险的介质,且介质无足以腐蚀和破坏绝缘的气体尘埃。

5、无显著摇动和冲击震动的地方。

接线时,常用电源N应接入常用电源执行断路器ON?,备用电源R应接入备用电源执行?断路器OR。当ONOR为四线断路器时,接线方式按接线图,其中ONOR的1、3、5为?三相(A、B、C)进线端,2、4、6为三相出线端,7为零线(N)进线端,8为零线出线端。若选用断路器为三极断路器,则必须将常用电源N)的零线NN和备用电源R)的零线NR同时接到三极专用接零线端子KG上。具体操作见接线图。双电源切换开关自动控制器的工作电源取断路器QNOR的进线端A相和零线N,若选用断路器为三极断路器时,必须要接零线NNNR,该三极专用接线零端子在两台断路器中间,在自动电源切换开关安装,接线过程中,切不要把原接在断路器进线端的本机控制器线忘掉,碰断或短路等。
