| Zusammenfassung: | The invention discloses a 10-66kV distribution network intermittent arc grounding true simulation test device comprising an MCU processing unit, a keypad, a switch output unit and an intermittent arcgrounding trigger unit connected between a phase line in the distribution network and ground, wherein the input end of the MCU processing unit is connected to the keypad for inputting control conditions, and the output end of the MCU processing unit is connected to the controlled end of the intermittent arc-grounded trigger unit via the switch output unit. The invention has a simple structure, andcan realistically and reliably simulate intermittent arc ground faults in distribution networks. The phase angle of arc ground faults is controllable, the duration of a single arc is controllable, and the interval time of each arc is controllable, which can meet the experimental requirements of different arc light ground faults and provides a reliable basis for the study of power system ground faults.
