Three-station isolation operating mechanism of gas insulated switchgear

The utility model discloses a three-station isolation operating mechanism of a gas insulated switchgear. Wherein the isolation operation shaft, the grounding operation shaft, the first microswitch andthe second microswitch are respectively installed on the support. The support is provided with an isolation operation hole and a grounding operation hole, the isolation operation shaft is connected with a first interlocking mechanism, and the isolation operation shaft drives the first interlocking mechanism to trigger the first microswitch, shield the grounding operation hole and indicate the isolation state. The grounding operation shaft is connected with a second interlocking mechanism, and the grounding operation shaft drives the second interlocking mechanism to trigger the second microswitch, shield the isolation operation hole and indicate the grounding state. According to the utility model, an original mechanism is improved; an original shaft core, an original plastic swing rod andan original opening and cl
