磁保持继电器是国家电网公司用电信息采集系统预付费控制的执行单元，其工作可靠性尤为重要，传统的检测方法只能实现单只检测，效率很低，难以满足智能电能表大力推广的实际需要。本文提出了一种用于智能电能表的磁保持继电器的批量测试技术，在被测的磁保持继电器两端并接一种电流自动旁路机构，通过控制拉合闸时序来实现多只磁保持继电器的批量同时检测，并研制了批量测试系统，可以实现多只继电器的同时测试，试验结果证明该技术切实可行。

Latching relay is the execution unit of State Grid Corporation pre-paid system, whose reliability is particularly important. Traditional detection methods of latching relay are inefficient in the sense that it can test only one latching relay at a time, therefore is difficult to meet the actual needs of vigorous promotion for smart meters. This paper presents a batch testing technique for latching relay, which parallels a type of current bypass unit in measured relay, realizing batch test for multiple latching relays by controlling the switching on and off sequence. Finally, a batch test system is developed, which can achieve batch test for multiple relays at a time. Test results show that the technique is feasible.
