Description

Technical Field

[0002] As energy demand continues to grow, the demand for output power of power equipment is also increasing. Existing power equipment includes multiple power modules and an installation cabinet, wherein multiple power modules are installed in the receiving portion of the installation cabinet to form a main body. However, the number of power modules of existing power equipment is fixed, and it is impossible to expand the power modules at the installation site, nor is it possible to increase the output power of the power equipment.

[0003] A standard container generally has a fixed size and can usually accommodate two main bodies for transportation. However, if an additional power module is first installed outside the main body in order to increase the output power of the power device, this will increase the overall volume of the power device, and the standard container can only accommodate one main body with an additional power module, which reduces transportation efficiency and wastes transportation resources.

[0004] On the other hand, the power module of the existing power device is a modular structure, and is limited by the volume and installation method of the main body, and the layout cannot be adjusted according to demand.

[0005] In view of this, it is necessary to develop a power device and an assembly method thereof to solve the problems faced by the prior art. Summary of the invention
