摘要
建筑工程在总配电柜处将TN-C供电系统转变为TN-S三相五线制供电系统,需完成重复接地工作。设计了重复接地的连接方法,避免了总配电柜处总剩余电流保护器的跳闸,且完成了配电系统转换,满足要求。
The repeated grounding connection is required when TN-C power supply system is transformed into TN-S three-phase supply system at total distribution cabinet of buihting projeet. This paper designed a new method of repeated ground cozmection to awfid the tripping of residual current protective device at the total power distribution cabinet. The distribution system transformation was completed to meet the requirements.
