1746-OB32E

1746-OB32E 根据GB13955-2005标准在低压配电系统中，当采用放射式供电时，一般宜选择两级分级保护。级保护应设在低压配电室引出的配电干线回路的首端；第二级保护应设在各防火分区、功能分区和楼层的分配电箱电源进线处、末端配电箱的进线处或分支线回路上。哈尔滨医科大学附属医院（群力区）低压配电系统采用放射式供电，级保护在低压配电室引出的配电干线回路的首端设漏电流互感器，然后通过探测器ARCM300将漏电信号传输至Acrel-6000/Q100电气火灾监控设备，实现对漏电电流、过电流、温度等信号的监测，然后发出声光信号报警，准确报出故障线路地址，监视故障点的变化，并储存各种故障和操作试验信号以及显示系统电源状态。
