Environment-friendly insulating gas closed switch equipment

The invention discloses environment-friendly insulating gas closed switch equipment. The equipment comprises a mounting outer box, a protective box door is connected to the middle of the front face of the mounting outer box through a hinge, a sealed inner cabinet is fixedly mounted in the middle of the inner side of the mounting outer box, and mounting frames are welded to the middles of the two sides in the sealed inner cabinet. A sealing square frame is fixedly connected to the edge portion of one side of the front face of the interior of the sealed inner cabinet, a sealing square door is installed on the front face of the sealed inner cabinet in an embedded mode, and a driving gear is rotationally connected to the middle of the bottom end of the sealed square door. Through cooperative use of two sealing modes, the leakage phenomenon of the insulating gas in the sealed inner cabinet during the use process of the switch equipment is effectively prevented, so that the service life of the switch equipment is e
