摘　　要：在多电源的通信局楼内,变压器的接地方式与变配电室内“杂散电流”的形成有着直接关系。而双电源设备前端ATS开关的极数选择,则与整个供电电路范围内“杂散电流”的形成有着直接关系。“杂散电流”本身可能会在某些场景下对供电系统产生一定的危害,需要引起足够的重视。In multi-power communication stations,the grounding pattern of transformer is directly related to the formation of‘stray current’in the power transformation in the distribution room.The pole number selection of ATSE of dual power supply equipment front-end,on the other hand,is directly related to the formation of‘stray current’in the whole power supply route.‘Stray current’itself may cause certain harm to the power supply system in some scenarios,which needs to receive adequate attention.
