Description

Technical Field

[0001] The utility model relates to the field of distribution plug frames, and particularly relates to a distribution plug frame for an energy storage system. Background Art

[0002] As a key component in the power system, the distribution plug frame is widely used in various occasions that require stable power supply, especially in energy storage systems, data centers, server rooms, and industrial control systems. Its main function is to safely and efficiently distribute and transmit electric energy to ensure that each electrical device can work properly. Especially in the energy storage system, the distribution plug frame not only is responsible for the distribution of electric energy, but also undertakes important tasks such as protecting the battery pack, monitoring the power state, and improving the overall operation efficiency of the system.

[0003] Existing distribution plug frames usually consist of multiple functional modules, including key components such as an AC input air switch, a lightning protection switch, a lightning arrester, an AC output switch, and an AC input / output terminal block. These components achieve the functions of electric energy input, distribution, protection, and monitoring through precise electrical connections and structural designs. Specifically, the AC input air switch is used to control the input of electric energy, the lightning protection switch and the lightning arrester are used to protect the system from external factors such as lightning, and the AC output switch and the terminal block are responsible for safely delivering the electric energy to each electrical device.

[0004] However, most of the existing supporting distribution modules and AC modules exist in a split form, that is, the distribution module and the AC module are generally separate cabinets, or the distribution and conversion of the existing energy storage system supporting are usually directly arranged separately on the cabinets of the system, and modular production and installation cannot be achieved, resulting in the inability to perform rapid layout and installation during the subsequent installation of the cabinets, thereby affecting the subsequent installation efficiency and usage efficiency. In addition, the existing directly distributed installation of the distribution and AC occupies a large space, resulting in a low space utilization rate inside the cabinet, affecting the integration degree of the energy storage system inside the cabinet, and being not conducive to subsequent overall installation and maintenance. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above defects, and provide a distribution plug frame for an energy storage system to solve the technical problems that the direct layout and installation of the distribution module and the AC module in the above background art are inconvenient, and the installation space utilization rate is relatively low, thereby being not conducive to integrated modular production and installation, and affecting subsequent overall installation and maintenance.
