When the outside air enters the inside of the distribution cabinet body through the ventilation grille, the outside air will enter the inside of the storage net through the vent and be discharged after being dried by the desiccant inside the storage net. The drying of the outside air by the desiccant facilitates the removal of moisture in the outside air and tries to prevent excessive moisture from entering the inside of the distribution box body;

[0003] At present, since the cabinet door of the power distribution cabinet is installed in a rotating hinged manner, there is still a certain gap between the cabinet door and the cabinet body after the cabinet door is closed. When encountering waves, water can easily enter the cabinet body through the gap and cause damage to internal components. When the cabinet door with a gap is soaked in seawater, water can easily seep back. The waterproof sealing effect of the cabinet body is poor, which reduces the stability of use at the seaside.
