Distribution network closes ring operation auxiliary system

The utility model relates to a distribution network closes ring operation auxiliary system, including signal collector, adc, it is first that close the ring detector and the second closes the ring detector, signal collector connects adc, still is used for connecting distribution network cutout ware both sides, adc is connected to the first ring detector that closes, the second closes the ring detector to be connected with adc radio communication, first closing is encircled detector and second and is closed and encircle the detector and export the ring condition of closing analysis result respectively. Through adopting the dual ring that closes to judge, can effectively prevent to judge by accident in order to reduce the emergence that parallel non - the same period, avoid the impact of big loop current, improved the fail safe nature of distribution network. 本实用新型涉及种配电网合环操作辅助系统，包括信号采集器、模数转换器、第合环检测器和第二合环检测器，信号采集器连接模数转换器，还用于连接配电网中断路器两侧，第合环检测器连接模数转换器，第二合环检测器与模数转换器无线通信连接，第合环检测器和第二合环检测器分别输出合环条件分析结果。通过采用双重合环判断，能有效防止
