摘　　要：在二次施工接线中,常出现不同直流电源间交叉、混接等错误导致的直流串电。结合现场经验和实际案例,归纳出4类串电情况,研究了针对不同串电类型的具体检测方法和操作流程,为作业人员在基建验收和保护检验中的串电测试提供了指导。In the secondary construction wiring,the DC misconnection is often caused by the connection error of crossing and mixed wiring between different DC power supplies.Combined with the field experience and actual cases,four types of power misconnection are summarized,and the specific detection methods and operating procedures for different misconnection types are studied,which can provide guidance for operators to test current misconnection in infrastructure acceptance and protection inspection.
