[0034] The blocking assembly includes two fixed cylinders 20 fixedly installed on the top of the inner wall of the opening and closing body 1, the interior of the two fixed cylinders 20 are movably connected with movable blocks 21, the tops of the two movable blocks 21 are fixedly connected with vertical rods 22, a blocking plate 23 is fixedly connected between the tops of the two vertical rods 22, and a return spring 24 is arranged at the top of the movable block 21 and on the outside of the vertical rod 22.

[0035] Working principle: When the switch is used outdoors, the humidity sensor 5 can monitor the humidity value inside the switch body 1, and transmit the monitored data to the PLC controller 6. When the humidity inside the switch body 1 reaches the preset value, the PLC controller 6 starts the blower 9, the drive motor 16 and the heating wire 4, and the solenoid valve 13 is opened synchronously, and the external air enters the dehumidification box 8 through the air inlet pipe 12. The activated carbon adsorption plate 10 in the dehumidification box 8 is used to adsorb and filter the moisture in the external gas. The filtered dry gas is transported to the diversion frame 2 through the hose 11, and the heating wire 4 is used to adsorb the moisture in the diversion frame 2. The dry gas is heated, and the heated dry gas is blown to the electrical equipment in the switch body 1 through the air outlet 7 to dry it, and at the same time, the output end of the driving motor 16 is driven to rotate clockwise or counterclockwise, driving the driving gear 17 to rotate synchronously, and then driving the driven gear 18 meshing with it to rotate, and driving the threaded rod 15 to rotate, and under the limiting effect of the guide rod 14 on the driving block 19, the driving block 19 moves upward or downward along the axial direction of the threaded rod 15, and then drives the diverter frame 2 to move and blow hot air to dry the electrical equipment, effectively increasing the blowing range, and facilitating efficient drying of the electrical equipment;

[0036] In the process of the dehumidification component blowing dry hot air into the switchgear body 1 to dehumidify the electrical equipment, external air is blown into the switchgear body 1, increasing its internal pressure, pushing the blocking plate 23 upward, and driving the movable block 21 upward to squeeze the return spring 24 to put it in a compressed state, and the blocking plate 23 moves to the side away from the air outlet 7, so that the air outlet 7 is automatically opened, which is convenient for the moisture in the switchgear body 1 to flow out from the air outlet 7, so that the dry air and the humid air in the switchgear body 1 can circulate, which is beneficial to improve the drying and dehumidification efficiency of the electrical equipment;

[0037] When the humidity in the switchgear body 1 is lower than the preset value, there is no need to perform dehumidification operation. The drive motor 16, the blower 9, the heating wire 4 and the solenoid valve 13 are turned off through the PLC controller 6. At this time, the internal pressure of the switchgear body 1 is the same as the external pressure, and then the elastic force of the reset spring 24 is used to reset the sealing plate 23, and the air outlet 7 is automatically blocked and closed to prevent external humid gas from entering the switchgear body 1 from the air outlet 7, thereby protecting the electrical equipment in the switchgear body 1.
