10-66kV distribution network intermittent arc grounding true simulation test device

The utility model discloses a 10-66kV distribution network intermittent arc grounding simulation test device. The device comprises an MCU processing unit, a keyboard plate, a switching value output unit and an intermittent arc grounding trigger unit connected between a phase line and the ground in a distribution network. The input end of the MCU processing unit is connected with a keyboard plate used for inputting control conditions, and the output end of the MCU processing unit is connected with the controlled end of the intermittent arc grounding trigger unit through the switching value output unit. The device is simple in structural form; according to the method, the intermittent arc grounding fault of the distribution network can be truly and reliably simulated, the occurrence phase angle of the arc grounding fault is controllable, the duration time of single arc light is controllable, the interval time of each arc light is controllable, the experimental requirements of different arc grounding faults can
