Description

Box-type substations are reliable in operation and easy to maintain, and are widely used in urban and rural areas. With the development of land, the construction of various facilities and the breeding of agricultural products all require temporary power supply, so a movable traction box-type substation is developed. Although the existing traction box-type substation has the advantage of being movable compared to the traditional box-type substation, it greatly increases the overall volume and does not change its original operation mode. All current operations require opening the outer door for operation, and the operator faces the cabinet, which poses a certain safety hazard to human safety protection.

The connection between the high-voltage side and the transformer unit is mostly in the form of direct connection with traditional cables, which makes the installation process complex and poses an electric shock risk. The low-voltage side outlet usually needs to open the cabinet door for power supply operation, which is neither convenient nor meets the rapid response needs of temporary power supply scenarios. At the same time, the overall waterproof performance of the equipment depends on the sealing structure of the shell, and the splicing part is prone to rainwater penetration, affecting the operation reliability of the equipment.
