Stage type high-voltage circuit trouble shooting device

The invention discloses a stage type high-voltage circuit trouble shooting device, including two high-voltage circuit iron towers. The two high-voltage circuit iron towers are fixedly connected with overhead ground wires through a bridge arranged at the top of the high-voltage iron towers, the overhead ground wires on the two high-voltage circuit iron towers are fixedly connected with two cables, a current sensor and a voltage sensor are respectively fixedly connected on outer surfaces of the overhead ground wires at two sides of the bridge, two sides of the current sensor and the voltage sensor are provided with fixed blocks, and the current sensor and the voltage sensor are connected with the fixed blocks through coils wound on the outer surfaces of the current sensor and the voltage sensor, and are electrically connected with the overhead ground wires. The stage type high-voltage circuit trouble shooting device can timely and accurately locate a fault point when an instant earth fault or permanent earth fault occurs in a circuit, so that maintenance personnel can rapidly remove the circuit fault by maintenance, thereby maximally avoiding influence on social production and daily life of people.
