It combines transformer step-down and low-voltage distribution functions organically and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box.

[0003] A Chinese patent with publication number (CN219203903U) discloses a box-type substation, including a box-type substation body, a top plate fixedly installed on the top of the box-type substation body, frames fixedly installed on both sides of the box-type substation body, fixing bars fixedly installed at both ends of one side of the frame, a heat sink fixedly installed in the middle of the fixing bar, a bracket fixedly installed at a position close to the heat sink inside the frame, a cooling fan fixedly installed in the middle of the bracket, and a baffle fixedly installed on the side of the frame away from the heat sink.

[0004] The defect of the above-mentioned selected technology is that the heat sink, cooling fan and baffle structures installed on both sides of the box-type substation body are to increase the air circulation inside the box-type substation, so as to make the heat dissipation effect inside the box-type substation better. However, the heat sink, cooling fan and baffle are fixedly installed with the box-type substation body. There will be a large amount of dust and impurities in the outside air. Under long-term air flow and heat dissipation, a large amount of dust will inevitably accumulate on the heat sink, cooling fan and baffle. If the dust is not cleaned in time, the heat dissipation efficiency will be seriously affected. Utility Model Content
