[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention uses a booster pump to extract insulating gas from the gas storage tank and injects it into the inner side of the gas injection chamber through a gas injection pipe. The gas delivery box uses a one-way valve to unidirectionally deliver the insulating gas, maintaining the unidirectional injection of insulating gas into the inner side of the protective box, achieving a positive pressure state in the protective box and providing continuous insulation filling treatment for the substation. Multiple filter plates and multiple adjustment handles are arranged linearly and alternately. The insulating gas in the protective box is delivered to the inner side of the return chamber through the gas delivery box and one of the conical plugs away from the gas injection chamber. Then, the insulating gas can be filtered multiple times by multiple filter plates and returned to the inner side of the condenser through the second return pipe. Multiple fan boxes in the heat dissipation box can form airflow on the outside of the heat dissipation fins through the vent plate, which facilitates the condenser to condense and remove dust from the insulating gas, effectively regulating the temperature and purity of the insulating gas.

[0018] 2. This invention uses a condenser to return insulating gas to the inside of the gas storage tank. The return heat dissipation module and the circulation purification module facilitate the circulation and processing of the insulating gas, maintaining the insulation operation of the substation inside the protective box and the quality of the insulating gas. By rotating multiple adjustment handles, the gap between the adjustment handles and the conical plug and the gas delivery box can be adjusted, thereby controlling the return position of the insulating gas in the gas delivery box and facilitating the replacement and maintenance of multiple filter plates.

[0036] In summary, when applying a skid-mounted substation, the substation is installed inside the protective box 101, allowing it to be sealed and protected by the protective box 101 and four doors 102. Multiple upwardly mounted cable mounting pipes 104 are used to install the cables connecting the substation inside and outside the protective box 101. Power is connected, and the gas storage tank 303 is filled with insulating gas. The booster pump 306 is started, drawing the insulating gas from the gas storage tank 303 and injecting it into the gas injection chamber 507 through the injection pipe 505. A one-way valve 508 is installed on the inner side of the bottom of the gas injection chamber 507, allowing the gas delivery box 501 to unidirectionally deliver the insulating gas through the one-way valve 508.

The insulating gas can be filtered multiple times by multiple filter plates 503 and returned to the inside of the condenser 404 through the second return pipe 405. Multiple heat dissipation fins provided at the upper end of the condenser 404 are inserted into the inside of the middle part of the heat dissipation box 401. The multiple fan boxes 406 in the heat dissipation box 401 can form airflow on the outside of the heat dissipation fins through the vent plate 402, which facilitates the condenser 404 to condense and remove dust from the insulating gas, and effectively regulates the temperature and purity of the insulating gas.

[0038] The condenser 404 then returns the insulating gas to the inside of the gas storage tank 303. The return heat dissipation module 4 and the circulation purification module 5 facilitate the circulation and processing of the insulating gas, maintaining the insulation operation of the substation in the protective box 101 and the quality of the insulating gas. The multiple adjusting handles 504 are rotated, which causes the adjusting handles 504 to drive the conical plug 509 to adjust the gap between the adjusting handles 504 and the gas delivery box 501, thereby controlling the return position of the insulating gas in the gas delivery box 501, which facilitates the replacement and maintenance of multiple filter plates 503.
