However, although the protective casing is added, when the temperature and humidity inside the protective casing deviate from the temperature and humidity inside the high-voltage cabinet, condensation will occur at the high-voltage cabinet. Condensation in the high-voltage cabinet will reduce the insulation strength of the equipment, and the system overvoltage may cause equipment failure, and even cause equipment damage or power outages in severe cases.

Two arc-shaped guide grooves are provided on the guide plates 641 .

[0057] Specific implementation process: In the present invention, when there is a large temperature difference between the high-voltage cabinet body 1 and the protective shell 2, and the humidity inside the high-voltage cabinet body 1 is high, the heater 3 is operated to heat and dry the gas between the high-voltage cabinet body 1 and the protective shell 2. Subsequently, the rotating motor 6323 is operated, and the rotating rod 631 is further rotated. When the rotating rod 631 rotates, the multiple first straight bevel gears 633 on the outside thereof are driven to rotate. When the first straight bevel gear 633 rotates, the second straight bevel gear 634 is rotated, and the second straight bevel gear 634 further drives the rotating shaft 84 thereon to rotate. That is, at this time, the rotating shafts 84 inside the multiple exchange cylinders 61 are all rotated, and when the rotating shaft 84 rotates, the swing plate 83 is further rotated. The two swing plates 83 pull the connecting support rod 82 to rotate through the rotating shaft, and the connecting support rod 82 is limited by the moving piston 81, and the moving piston 81 is further reciprocated downward and upward along the inside of the exchange cylinder 61.

[0058] When the movable piston 81 moves downward along the inside of the exchange cylinder 61, the negative pressure between the movable piston 81 and the circular plate 621 increases, further causing the sealing plate 71 at the bottom of the circular plate 621 to separate from the through hole 6211, and the external dry gas enters the air inlet end through the air inlet pipe 66, and then enters the cavity formed between the movable piston 81 and the exchange cylinder 61 along the through hole 6211 at the air inlet end;

[0059] When the movable piston 81 moves upward along the bottom end of the exchange cylinder 61, the pressure between the movable piston 81 and the circular plate 621 increases, further sealing the sealing plate 71 at the bottom of the circular plate 621 with the corresponding through hole 6211, and the sealing plate 71 at the top of the circular plate 621 is separated from the through hole 6211, and the dry airflow enters the high-voltage cabinet body 1 through the through hole 6211 from the air outlet pipe 67, and as the dry gas is discharged from multiple exchange cylinders 61, and at the same time, the multiple guide plates 641 rotate, so that the dry gas is further fully filled into the high-voltage cabinet body 1, so as to neutralize the gas with high humidity inside the high-voltage cabinet, and further prevent the high-voltage cabinet body 1 from condensing;

[0060] At the same time, in this embodiment, when there is a large temperature difference between the high-voltage cabinet body 1 and the protective shell 2, and the humidity inside the high-voltage cabinet body 1 is low, the interior of the high-voltage cabinet body 1 is in a relatively dry state. An overly dry environment is also likely to cause static electricity inside the high-voltage cabinet body 1 and a temperature difference between the inside and outside of the high-voltage cabinet body 1, resulting in condensation. Therefore, at this time, the heater 3 does not run, but the rotating motor 6323 runs, further allowing the outside gas to enter the high-voltage cabinet body 1 for neutralization, thereby further preventing condensation from occurring in the high-voltage cabinet body 1.

[0061] See also Figure 3 to Figure 4 and Figures 13 to 15 The exhaust member 65 includes an exhaust cylinder 651, a rotating sleeve 652, an air guide branch pipe 653, a connecting frame 654, an exhaust fan 655, a rotating member 656 and a synchronization rod 657.

The air intake fan 52 is located inside the circulation shell 51, and the air intake fan 52 is installed on the top of the synchronization rod 657. A plurality of air inlets are arranged around the circulation shell 51.

[0066] Specific implementation process: that is, when the rotating sleeve 652 rotates, the intake fan 52 is driven to rotate synchronously through the synchronization rod 657. At this time, the humid airflow discharged from the high-voltage cabinet body 1 enters the air guide pipe 53 and is finally discharged from the exhaust pipe 54. The discharged humid airflow is heated and dried by the heater 3 inside the protective shell, which further plays a role in preventing condensation on the high-voltage cabinet body 1.

[0067] Embodiment 2

[0068] See also Figure 13 to Figure 14 , Embodiment 2 is a further supplementary description of the closing member 9 in Embodiment 1, specifically: the closing member 9 includes a support frame 91, a support rod 92, a buffer spring 93, a support sleeve 94 and a rubber sealing plug 95, the support frame 91 is fixedly installed inside the gas guide branch pipe 653, one end of the support rod 92 is fixedly connected to the support frame 91, and the support sleeve 94 is slidably sleeved on the outside of the other end of the support rod 92, the buffer spring 93 is sleeved on the outside of the support rod 92, and the two ends of the buffer spring 93 are respectively fixedly connected to the support sleeve 94 and the support rod 92, and the rubber sealing plug 95 is fixedly installed on the outside of the support sleeve 94;

[0069] Specifically, when the rotating sleeve 652 does not rotate, under the elastic force of the buffer spring 93, the supporting sleeve 94 is stably sleeved on the outside of the supporting rod 92, and the rubber sealing plug 95 is connected to the opening to further seal the gas branch pipe 653. In this state, the high-voltage cabinet body 1 is ensured to be in a sealed state.

[0070] At the same time, when the rotating sleeve 652 rotates, the centrifugal force generated by the rotation causes the supporting sleeve 94 to move in a direction away from the supporting rod 92, further causing the sealing plug to detach from the opening, thereby keeping the opening of the gas branch pipe 653 in a conductive state, further facilitating the discharge of gas.
