小电阻接地系统线路检测设备和系统
摘要：
本实用新型涉及一种小电阻接地系统线路检测设备和系统，小电阻接地系统线路检测设备包括：处理装置和交流量采集装置，所述处理装置包括第一比较器和第二比较器；所述第一比较器分别与所述交流量采集装置以及第二比较器相连接，所述第二比较器与跳闸出口装置相连接。上述小电阻接地系统线路检测设备和系统，通过在处理装置中设置第一比较器和第二比较器，以及交流量采集装置与处理装置的配合，能检测出小电阻接地系统高阻接地时的故障线路，且不需要验证专用零序CT的极性，具有良好的检测效果。
摘要（英）：

The utility model relates to a little grounding system wiring check out test set and system, little grounding system wiring check out test set includes: processing apparatus and friendship traffic collection device, processing apparatus includes first comparator and second comparator, first comparator respectively with hand over traffic collection device and second comparator to be connected, thesecond comparator is connected with tripping operation outlet device. Above -mentioned little grounding system wiring check out test set and system is through setting up first comparator and second comparator in processing apparatus to and the cooperation of handing over traffic collection device and processing apparatus, fault line in the time of detecting out little grounding system high resistant ground connection just need not verify special zero sequence CT's polarity to have good detection effect.
