[0029] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] One embodiment of this utility model provides an energy storage converter cabinet, which is connected between the battery cluster and the transformer, such as... Figures 1 to 6 As shown, the energy storage converter cabinet includes a cabinet frame 1, input cables (not shown in the figure), output copper busbars 2, busbars 3, and multiple energy storage converter units 4. The number of energy storage converter units can be set as needed.

[0031] Specifically, the busbar 3 and the plurality of energy storage converter units 4 are arranged inside the cabinet frame 1, each energy storage converter unit 4 is connected with the busbar 3 through a conductive member 5, each conductive member 5 is provided with an alternating current switch 6, one end of an input cable is inserted into the cabinet frame 1 from the bottom of the cabinet frame 1, the other end of the input cable is used to connect a battery cluster, each energy storage converter unit 4 is connected with the input cable through a branch cable, each branch cable is provided with a direct current switch 7, one end of an output copper bar 2 is inserted into the cabinet frame 1 from the front side of the cabinet frame 1, the other end of the output copper bar 2 is used to connect a transformer, the busbar 3 and the output copper bar 2 are connected through a control switch 8. In this way, the on-off between the alternating current side of the corresponding energy storage converter unit 4 and the transformer can be controlled through the alternating current switch 6, the on-off between the direct current side of the corresponding energy storage converter unit 4 and the battery cluster can be controlled through the direct current switch 7, and the on-off between the entire energy storage converter cabinet and the transformer can be controlled through the control switch 8.

[0032] In summary, in the energy storage converter cabinet of the embodiment, the alternating current switch is arranged on the conductive member between the energy storage converter unit and the transformer, and the direct current switch is arranged on the branch cable between the energy storage converter unit and the battery cluster, so that each energy storage converter unit has an independent switch for on-off control, which facilitates the maintenance or repair of the energy storage converter unit in the non-stop state of the entire system, and can effectively reduce the property loss caused by the stop of the entire system due to maintenance or repair.

[0033] In the embodiment, as shown in Figure 5 and Figure 6 , the cabinet frame 1 has an upper and lower layer structure, the plurality of energy storage converter units 4 are arranged on the upper layer of the cabinet frame 1 along the length direction of the cabinet frame 1, and the input cable, the output copper bar 2, the busbar 3, the control switch 8, each alternating current switch 6 and each direct current switch 7 are arranged on the lower layer of the cabinet frame 1. In this way, not only the length of the cable used in the energy storage converter cabinet is less, but also the maintenance and repair of the energy storage converter cabinet are facilitated.

[0034] In addition, as shown in Figures 1 to 6 , the top of the cabinet frame 1 is provided with an inverted V-shaped top cover 9, when the energy storage converter cabinet is arranged outdoors, the top cover 9 can shield rainwater and make the rainwater slide from the left and right sides of the top cover 9, preventing the rainwater from gathering on the top cover 9, and the lower layer of the cabinet frame 1 is covered with a lower sealing plate 10, and a sealing glue or a sealing ring is arranged between the lower sealing plate 10 and the cabinet frame 1, which can realize the waterproof and moisture-proof of the energy storage converter cabinet, so as to meet the use of outdoor scenes.

[0035] In addition, the cabinet frame, the top cover and each lower sealing plate are coated with a corrosion-resistant coating, thereby further enhancing the corrosion resistance of the energy storage converter cabinet.

[0038] In this embodiment, the upper layer of the rack frame adopts an open structure, i.e., as shown below. Figures 1 to 4 As shown, only the upper right side of the cabinet frame 1 is covered with an upper sealing plate 13, exposing the energy storage converter unit 4 to the external environment and improving the heat dissipation effect of the energy storage converter unit 4. Of course, the upper sides of the cabinet frame may not be covered with upper sealing plates.

[0039] In addition, such as Figures 1 to 5 As shown, the top of the cabinet frame 1 is provided with lifting rings 14, specifically four lifting rings 14, which are respectively set at the corners of the cabinet frame 1, so that the energy storage converter cabinet can be lifted by the lifting rings 14, thereby facilitating its transportation. Of course, in other embodiments, the lifting rings can also be replaced by hooks, which are also within the protection scope of this utility model.

[0040] Furthermore, the control switches, all DC switches, and all AC switches are circuit breakers. Because circuit breakers are easy to operate, the energy storage converter unit can be quickly and smoothly disconnected with just a slight movement of the switch; moreover, circuit breakers can quickly disconnect faulty circuits, preventing the fault from escalating, reducing the impact on the entire system, and improving the stability and reliability of the entire system.

[0041] In other embodiments, the upper perimeter of the cabinet frame is covered with an upper sealing plate, which encapsulates and protects the energy storage converter unit.

[0042] The top cover is made of transparent plastic or transparent acrylic sheet; this allows the working status of the energy storage converter unit to be observed through the top cover.

[0043] The above merely illustrates the specific implementation of the present application, and based on the above teaching, those skilled in the art can make other improvements or modifications on the basis of the above examples. Those skilled in the art should understand that the above specific description is only for better explaining the purpose of the present application, and the protection scope of the present application should be subject to the protection scope of the claims.
