It organically combines the functions of transformer step-down and low-voltage distribution 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. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after the civil substation. The box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of power transformation and distribution equipment.

[0003] Prefabricated substations need to be ventilated and cooled when in use. However, prefabricated substations are installed outdoors and mostly use shutters and protective filters to dissipate heat.

How to protect the electrical components inside the prefabricated substation while ensuring heat dissipation performance is a problem that prefabricated substations need to solve. To this end, we propose a miniaturized prefabricated substation with an external double-layer ventilation structure. Utility Model Content
