[0023] Example

[0024] The combiner cabinet, a crucial component of the energy storage container, connects the energy storage DC system and the energy storage converter. Most combiner cabinets integrate the power distribution cabinet function, but this also presents some problems. The connection between the DC system and the combiner cabinet requires additional power distribution wiring. This excessive number of wires complicates wiring and installation, and increases inspection and maintenance time. The addition of the power distribution cabinet also increases the size of the combiner cabinet, and the excessive number of components complicates the production process. Specifically, these problems include the following three:

[0025] 1. There are many cables connecting the power distribution compartment with the DC system and energy storage converter. The wiring using terminal blocks is complicated and prone to misconnection or missed connection, which creates safety hazards and makes subsequent inspection and maintenance difficult.

[0026] 2. The combiner cabinet has many internal components, complex design, and difficult production and installation;

[0027] 3. The junction box has low integration and is too large, making it inconvenient to transport and increasing the size of the energy storage container.

[0028] like Figures 1-6As shown, a modular junction cabinet is shown. The junction cabinet body 1 is mainly composed of a distribution box 5, a junction module 6, and a UPS module 3. The distribution box 5 is electrically connected to the UPS module 3 and the junction module 6 respectively. Several groups of paired guide rails 2 are fixedly installed inside the junction cabinet body 1. The UPS module 3, the distribution box 5, and the junction module 6 are installed in the junction cabinet body 1 through the guide rails 2 from top to bottom. The distribution box 5 is horizontally integrated with current transformers, switching power supplies, surge protectors, intermediate relays, switches, serial port relays and other components. Through high-integration design, the space utilization rate in the distribution box 5 is improved, the volume of the distribution box is reduced, and installation is convenient. The UPS module 3 is composed of a UPS battery and a UPS. By changing the original vertical distribution part to a horizontal arrangement and integrating it inside the distribution box 5, the horizontal space inside the junction cabinet body 1 is effectively utilized.

[0029] In some optional embodiments, electrical components that need to be connected and operated, such as a connector socket 7, an indicator light 9, an air switch 8, a spare socket 15, and an electric meter 16, are installed on the front side of the distribution box 5 to facilitate operation of the switch and subsequent maintenance.

[0030] In some optional embodiments, the connector socket 7 includes a power socket, a signal socket, and a communication socket. The connector socket 7 is used to connect external cables. The end of the external cable is fixedly connected to a connector plug that matches the connector socket 7. The external cable is connected to the distribution box 5 through the connector plug and the connector socket 7. The connector socket 7 can be designed to different types and sizes according to the electrical accessories to be connected. The external cables are connected one-to-one with the connector socket through the connector plug, which simplifies the wiring steps, avoids wiring errors, and reduces the possibility of electrical accidents.

[0031] In some optional embodiments, the confluence module 6 is composed of an isolating switch 10 , a connecting copper busbar 11 , and a fuse 12 . The isolating switch 10 is electrically connected to the fuse 12 via the connecting copper busbar 11 .

[0032] In some optional embodiments, ear plates 13 for connecting to the guide rail 2 are fixedly connected to the left and right sides of the bottom of the disconnector 10 .

[0033] By designing the isolating switch 10 , the connecting copper bus 11 and the fuse 12 into a modular structure, it is convenient to connect and install them with the guide rail 2 .

[0034] The distribution box 5 adopts a modular design, which concentrates all the distribution components in it. The front end of the distribution box 5 is installed with connector sockets 7, indicator lights 9, air switches 8, electric meters 16, spare sockets 15 and other electrical components that need to be connected and operated, which is convenient for operating switches and subsequent maintenance. The connector sockets 7 include power sockets, signal sockets, communication sockets, etc. External cables are connected to the distribution box 5 through connector plugs. The plugs and sockets correspond one to one and have a fool-proof design, which solves the problem of too many cables, avoids wrong connections and missed connections, causes safety hazards, and improves the efficiency of subsequent inspection and maintenance.

[0035] The distribution box 5 is internally installed with components such as current transformers, switching power supplies, surge protectors, intermediate relays, switches, and serial relays. The highly integrated design maximizes the space utilization inside the distribution box, reduces the volume of the distribution box, and facilitates installation. It can also reduce the volume of the junction box at the same time, saving costs and facilitating transportation and installation. In addition, as an important component of the energy storage container, the reduction in the volume of the junction box has a great promoting effect on the reduction in the size of the container.

[0036] The distribution box 5, the convergence module 3, the UPS, the UPS battery and other modules are rack-mounted, and each module is pushed in and supported by the guide rail 2, which is convenient for installation and subsequent operation and maintenance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
