[0002] An energy storage system refers to a system that stores electrical energy or other forms of energy through different media and releases it when needed. The energy storage system is a part of the object or space range defined for the research object, and it involves the input and output of energy, as well as energy conversion and storage devices. The energy storage system is a complex energy system that requires multiple indicators to describe its performance, such as energy storage density, energy storage power, energy storage efficiency, energy storage price, and impact on the environment. It is a technology developed to achieve the utilization of energy and the balance between supply and demand, and its core lies in energy conversion and storage. The basic principle of the energy storage system is to store energy in the form of chemical, physical, or mechanical energy in the device, and when energy is needed, the energy in the energy storage device is released through the reverse process and supplied to the load for use.

[0003] The energy storage system usually includes a high-voltage distribution part and an auxiliary distribution part, and the auxiliary distribution and high-voltage distribution complement each other in the power system. The high-voltage distribution system is responsible for stably delivering high-voltage electrical energy to each power consumption area, while the auxiliary distribution system is responsible for providing power support for the auxiliary equipment and control systems in these areas. The two work together to ensure the overall stable, reliable, and safe operation of the power system.

[0004] In the existing energy storage system, the supporting auxiliary distribution and high-voltage box are separated and arranged in two different places on the system cabinet, and then connected through conductors. It is rather troublesome during cabinet installation. The auxiliary distribution, high-voltage box, and conductors all occupy the space of the cabinet, resulting in a larger volume of the cabinet. Moreover, when the cabinet is opened for operation in rainy weather, rainwater is likely to splash on the switches and terminals on the surface of the distribution box. Since rainwater is corrosive, it shortens the service life of the distribution box. Summary of the Utility Model
