High-voltage isolating switch capable of cutting off induced current

The utility model discloses a high-voltage isolating switch capable of cutting off induced current. An auxiliary ground loop is connected with the main ground loop of the isolating switch in parallel and comprises an auxiliary moving contact which is attached on a main ground cutter bar, an auxiliary fixed contact which is installed on the fixed contact of the isolating switch, and a vacuum load switch which is electrically connected with the auxiliary moving contact through a connecting cable. The auxiliary moving contact is in parallel with the main ground moving contact. The front end of the auxiliary moving contact extends axially and forward and protrudes the front end of the main ground moving contact. The auxiliary fixed contact is installed above a main ground fixed contact and is a U-shaped structure formed by tubular bodies or bar bodies and the diameter of the auxiliary fixed contact is larger than the diameter of the main ground fixed contact. The vacuum load switch is connected with a main ground
