[0003] In the related art, some box-type substations are generally installed outdoors. In winter, the outer wall of the box-type substation is prone to ice, which affects the opening of the box door of the box-type substation. In addition, the outer wall of the box-type substation is frozen for a long time, which is easy to freeze the outer wall of the box-type substation. At present, artificial deicing is generally adopted, but the efficiency of artificial deicing is low. Summary of the invention

[0007] By adopting the above technical solution, during deicing, power is supplied to the electric heating plate, the electric heating plate generates heat, and then the electric heating plate is driven to move in a vertical direction by the driving component, so that the outer wall of the shell can be de-iced. This de-icing method has a simple structure and is easy to operate, and the de-icing efficiency can be improved by electric de-icing.

[0008] Optionally, the driving assembly includes a motor and a screw rod, the screw rod is rotatably connected to the shell, the screw rod rotates to drive the electric heating plate to slide, and the motor is used to drive the screw rod to rotate.
