摘　　要：小型无人值守通信机房包括移动基站、接入网机房及小型传输节点机房等,由于电源跳闸故障发生率很高,给机房维护带来巨大的成本负担和人力消耗。调查分析表明引起跳闸的主要原因是漏电保护器的误动和雷击电流超限。使用具有较高防雷能力的自动重合闸装置即可以解决跳闸问题,同时配合漏电保护器也能消除TT供电系统单相对地短路电流较小无法启动过流保护装置的重大的安全隐患。Smal unattended communication equipment room includes mobile base station,access network equipment room and smal transport node room. The high power trip fault rate brings large cost burden and human consumption. On investigation and analysis,it shows that the causes of trip are the fault touch of leakage protector and ultra lightning stroke current. The auto-matic reclosing device with higher lightning protection capability can solve trip problems. Combined with leakage protector,the device can remove some major hidden danger such as unable start of over-current protective device.
