[0002] In the prior art, with the rapid development of the power grid, a new type of intelligent energy storage cabin power station has been widely promoted and applied in China. The energy storage cabin generates huge heat during charging and discharging, and ventilation is required to remove the heat. However, there is a contradiction in the overall ventilation and closed system design of the energy storage cabin.
[0003] At present, the energy storage cabin is mainly ventilated and protected by an external ventilation filter window. However, the cabin structure with an external ventilation filter window cannot be completely sealed, resulting in the cabin not being isolated from the external environment. When the external environment is in a harsh state, the internal electrical equipment is susceptible to moisture, wind, sand, dust, etc., causing equipment short-circuit safety hazards, which has an impact that cannot be ignored on the normal operation of the entire energy storage system. In the Chinese patent with application number 202010755395.1, the exhaust system of the energy storage cabin adopts a multi-stage filtration form, and realizes the unity of ventilation and filtration through electric shutters and dust filter bags. However, the exhaust port of this solution is on the side wall of the energy storage cabin. In harsh environments such as strong winds and sand, the protection is poor, and it is integrated with the energy storage cabin, which is not conducive to maintenance and replacement when problems occur.
