1. a kind of environmentally friendly gas-insulated ring network cabinet, it is characterised in that including:

  • Cabinet;

    In the gas tank of closed structure, the gas tank is setIn on the cabinet;

    Entrance bushing, the entrance bushing is fixed on the upside of the gas tank in the horizontal direction;

    Bus box, it is describedBus box is fixed on the inner side of the gas tank, and the bus box and the entrance bushing are in relative arrangement;

    Main busbar, instituteMain busbar is stated to be electrically connected between the entrance bushing and the bus box;

    Three-phase high-voltage vacuum switch, the three-phase high-voltageVacuum switch includes insulating boot, vacuum interrupter, breaking main shaft, guiding joint, rod assembly, insulating contact, insulating base, conductionSeat, three station swing arms, isolation blade and grounding contact, the insulating boot are fixed on the inner side of the gas tank, and the vacuum is gone outArc chamber is fixed in the insulating boot, and the breaking main shaft is articulated on the inner side of the gas tank, the lower end for being oriented to jointThe upper end of the vacuum interrupter is fixed on, the rod assembly is connected in the upper end of the guiding joint and the open circuitBetween main shaft, the insulating contact is fixed on the lower end of the insulating boot, and the insulating contact is electrically connected at the vacuumThe lower end of arc-chutes, the insulating base is fixed on the inner side of the gas tank, and the conductive seat is fixed on the insulating base, instituteState three station swing arms to be articulated in the gas tank, the isolation blade is fixed in the three stations swing arm, and the isolation knifePiece is electrically connected on the conductive seat, and the grounding contact is fixed on the inner side of the gas tank, and the isolation blade hasGround connection station and a position spaced apart that the one connection station contacted on the insulating contact, one contact at the grounding contactIntermediate stations between the insulating contact and the grounding contact;

    Flexible cord is arranged, and the flexible cord row is electrically connected at the motherBetween the upper end of line box and the vacuum interrupter;

    Outlet casing tube, the outlet casing tube is vertically fixed on the gas tankBottom;

    Branch busbar, the branch busbar is electrically connected between the conductive seat and the outlet casing tube;

    Breaking drive mechanism,The breaking drive mechanism is on the cabinet, and the breaking drive mechanism is connected on the breaking main shaft, describedBreaking drive mechanism drives the breaking main axis to drive the rod assembly traction guiding joint to move up and down;

    AndIsolation drive mechanism, the isolation drive mechanism is on the cabinet, and the isolation drive mechanism driving is connected to described threeIn station swing arm, it is described to drive the isolation blade to switch on that the isolation drive mechanism drives the three stations swing arm to rotateConnect between station, intermediate stations and ground connection station.
