[0055] The working principle and use process of the present invention are as follows: when in use, the user performs maintenance and repair on the cabinet 1 by opening the cabinet door body 2. When the cabinet door body 2 needs to be completely sealed after the repair is completed, the cabinet door body 2 is first closed and the cylinder 601 is started. The cylinder 601 drives the tooth plate 602 to move to both sides. The tooth plate 602 pushes the gear 603 to rotate during the movement. The gear 603 drives the shaft rod 4 to rotate. The shaft rod 4 drives the baffle 5 to rotate in the opposite direction and moves it away from the side of the shaft rod 4 to the front of the cabinet 1. When the sealing gasket 13 on the back of the baffle 5 contacts the surface of the cabinet door body 2 and the cabinet 1 respectively, the connection of the gap between the cabinet 1 and the cabinet door body 2 is completed, and the cabinet door body 2 can be fixed at the same time. During the operation of the cabinet 1, the heat inside the cabinet 1 is transferred to the inside of the heat conducting plate 702 through the partition plate 701, and the heat conducting plate 702 exchanges heat with the external air, thereby achieving the effect of avoiding the influence of high sealing on the heat dissipation of the cabinet 1.

[0056] To sum up: this indoor gas-insulated fully sealed switch equipment with high sealing performance drives the shaft 4 to rotate through the transmission mechanism 6, and the shaft 4 drives the baffle 5 to rotate in the opposite direction and move it away from the side of the shaft 4 to the front of the cabinet 1. When the back of the baffle 5 contacts the surface of the cabinet door body 2 and the cabinet 1 respectively, the connection of the gap between the cabinet 1 and the cabinet door body 2 is completed, and the cabinet door body 2 can be fixed at the same time, which solves the problem of poor sealing of existing gas-insulated metal-enclosed switch equipment. After the cabinet door is closed, a gap will appear between the cabinet door and the switch equipment, which seriously affects the sealing effect of the gas-insulated metal-enclosed switch equipment and easily causes gas leakage during the operation of the gas-insulated metal-enclosed switch equipment.
