DETAILED DESCRIPTION

[0026] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0027] like Figure 1-Figure 8 As shown, the energy storage cabinet provided in this embodiment includes: an energy storage cabinet body 1, inside which is arranged a confluence chamber 102. The confluence chamber 102 includes: a front cavity 3 and a rear cavity 4, and the front cavity 3 is divided into a first cavity 301 and a second cavity 302 distributed on the left and right.

[0028] The front cavity 3 and the rear cavity 4 are adjacent to each other front to back. When the operator opens the front compartment door 1021, he can directly face the front cavity 3, which is conducive to directly checking the components inside.

[0029] The first cavity 301 and the second cavity 302 distributed on the left and right allow different components to be separated in space, reducing mutual interference and facilitating optimization of the internal layout.

[0030] The inverter 5 and the high-voltage box 6 are vertically arranged in the first cavity 301. Considering that the inverter 5 and the high-voltage box 6 occupy a large horizontal area, this vertical arrangement helps to save space and reduce the horizontal area.

[0031] A power distribution installation board 8 is fixedly installed in the second cavity 302, a guide rail group 9 is fixedly installed on the front wall of the power distribution installation board 8, and a power distribution assembly 10 is slidably arranged on the guide rail group 9. The power distribution assembly 10 is connected to the guide rail group 9 by sliding fit.

[0032] After the power distribution assembly 10 is mounted on the power distribution mounting plate 8 through the guide rail assembly 9, it can slide left and right to adjust its position. This design provides a high degree of flexibility, making it easier to add or replace the power distribution assembly 10, and also facilitates troubleshooting and maintenance.

[0033] In this embodiment, a station control integrated machine 7 is also fixedly installed in the second cavity 302, and is distributed adjacent to the power distribution installation board 8 above and below, which corresponds to the layout of the inverter 5 and the high-voltage box 6, and also realizes efficient use of space.

[0034] In this embodiment, the power distribution installation plate 8 includes: a vertical plate 801 and a horizontal plate 802 which are vertically connected to each other, and the vertical plate 801 is located at the front end of the horizontal plate 802 .

[0035] The guide rail assembly 9 is fixedly mounted on the front wall of the vertical plate 801 . A first channel 11 runs through the front wall of the vertical plate 801 to the rear. The connecting wires of the internal or external components of the energy storage cabinet 1 can be connected to the power distribution assembly 10 on the front wall of the vertical plate 801 through the first channel 11 .

[0036] Since the vertical plate 801 is located at the front end of the horizontal plate 802 , that is, at the front end of the second cavity 302 , such a position ensures that the operator can directly operate the power distribution assembly 10 on the vertical plate 801 after opening the front compartment door 1021 .

[0037] In this embodiment, a protective plate 14 is fixedly installed on the front wall of the vertical plate 801, and a second channel 15 runs through the front wall of the protective plate 14 backward. The operable part 17 of the distribution component of the front wall of the vertical plate 801 is inserted outward from the second channel 15, so that the distribution component 10 will not be completely exposed to the outside, which not only increases the safety of the operator, but also improves its own protection.

[0038] In this embodiment, a cavity 16 is provided between the protective plate 14 and the vertical plate 801. The cavity 16 is the space where the non-operable part 18 of the power distribution assembly is located, ensuring that most of the power distribution assembly 10 is not exposed to the outside.

[0039] In this embodiment, the left and right ends of the protective plate 14 are both provided with bending portions 1401, and the two bending portions 1401 are respectively connected to the front walls of the vertical plate 801. At this time, a cavity 16 for accommodating the non-operable part 18 of the distribution component is formed between the protective plate 14 and the vertical plate 801.

[0040] The protection plate 14 is a flat plate structure as a whole, and its left end is first bent backwards and then bent outwards to form a bent portion 1401 at the left end of the protection plate 14. The same is true for the bent portion 1401 at the right end of the protection plate 14.

[0041] In this embodiment, an energy storage bin 101 is further provided inside the energy storage cabinet 1, and the energy storage bin 101 and the confluence bin 102 are vertically distributed. An energy storage battery cluster 2 is installed in the energy storage bin 101.

[0042] A liquid cooling chamber 103 is provided between the energy storage chamber 101 and the confluence chamber 102 . A liquid cooling unit 12 is installed in the liquid cooling chamber 103 . The liquid cooling unit 12 cools the energy storage battery cluster 2 above it through a plurality of liquid cooling pipes 13 .

[0043] In this embodiment, the power distribution assembly 10 includes but is not limited to an air switch 1001, a two-way electric meter (not marked in the drawings) and a rotary switch (not marked in the drawings). Taking the air switch 1001 as an example, its operable part is a push rod 10011 for connecting or disconnecting a circuit.

[0044] In this embodiment, the rear cavity 4 passes through the rear side and the bottom side of the energy storage cabinet 1, and the operator can open the rear door 1022 to install or arrange the cables or components accommodated in the rear cavity 4. When the energy storage cabinet cooperates with other energy storage cabinets or other devices, the cables between them can pass through the bottom side of the energy storage cabinet 1 into the rear cavity 4, and then lead to the corresponding electrical components.

[0045] To sum up, in this embodiment, the power distribution installation plate 8 provided in this embodiment adopts a structure in which the vertical plate 801 and the horizontal plate 802 are vertically connected, and the vertical plate 801 is located at the front end of the second cavity 302, ensuring that the operator can directly operate the power distribution component 10 on the vertical plate 801 after opening the front compartment door 1021.

[0046] The front wall of the vertical plate 801 provided in this embodiment is further provided with a protective plate 14, and a second passage 15 is opened on the protective plate 14, and only the operable part 17 of the power distribution component is allowed to pass through the second passage 15. A cavity 16 is formed between the protective plate 14 and the vertical plate 801 to accommodate the non-operable part 18 of the power distribution component. Such a design improves safety protection while ensuring operational convenience.

[0047] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
