DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] It is easy to understand that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various interchangeable structural forms and implementation methods. Therefore, the following specific embodiments and the accompanying drawings are only exemplary illustrations of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0018] Combined with an embodiment of the present utility model Figures 1 - 3 shown as follows.

[0019] For the overall structure, as Figure 1 shown, the distribution box for dual-power distribution equipment includes: a box-shaped outer frame 1 spliced by C-shaped steel. The outer frame 1 is divided into a first vertical column 2 and a second vertical column 3, and each vertical column is divided into multiple layers from top to bottom. The first vertical column 2 includes an electric meter layer 4 and at least two power layers 5 with the same structure. Each power layer 5 includes an instrument door 6, a rear sealing plate 7, and a circuit breaker mounting plate 8. The instrument door 6 is correspondingly installed on the outside of the outer frame 1 and is hinged to the corner of the outer frame 1 through a hinge 23. The rear sealing plate 7 is located at the junction of the first vertical column 2 and the second vertical column 3 and is relatively fixed to the instrument door 6. The electric meter layer 4 is located at the top of the power layer 5, and it includes a metering chamber partition 9 for demarcating the power layer 5 and a metering chamber door panel 10 on the same side as the instrument door 6. An inverted V-shaped electric meter mounting plate 11 is vertically fixed on the metering chamber partition 9. A plurality of busbar frame supports 19 are fixed in the second vertical column 3.

[0020] Through the above structural design, for the installation space required for dual power, in this distribution box, it is accommodated by two adjacent power layers 5 up and down. In each power layer 5, an instrument door 6 and a circuit breaker mounting plate 8 are correspondingly provided, which is convenient for subsequent power supply access control and external data display. The rear sealing plate 7 at the back can ensure that the internal electrical components do not fall off. Similarly, a plurality of busbars on the cross beam 18 in the second vertical column 3 can facilitate the subsequent wiring of electrical components. The overall structure design of the outer frame 1 is ingenious and the layout is reasonable.

[0021] Specifically, in this embodiment, a shared partitioned top layer 12 is further provided at the tops of the first vertical column 2 and the second vertical column 3. A first busbar frame 13 is vertically fixed in the top layer 12, and a busbar frame core 14 is sleeved in the first busbar frame 13.

[0022] Furthermore, a second bus bar frame 15 is horizontally and fixedly arranged at the position of the second vertical column 3 corresponding to the electric surface layer 4. An insulator mounting plate 16 is also fixedly arranged at the junction of the electric surface layer 4 and the second vertical column 3. A third bus bar frame 17 is vertically and fixedly arranged at the position of the second vertical column 3 corresponding to the power supply layer 5. The two vertical C-shaped steels in the first vertical column 2 and the second vertical column 3 are fixed into a whole by a plurality of cross beams 18. The second bus bar frame 15 and the second bus bar frame 15 are respectively and fixedly arranged on the cross beam 18. A bus bar frame support 19 for connecting the outer frame 1 is further arranged at the bottom of each bus bar frame support 19.

[0023] The cross beam 18 can not only further strengthen the strength of the whole outer frame 1, but also provide enough space for the installation positions of the second bus bar frame 15 and the third bus bar frame 17. The whole second vertical column 3 is basically empty without adding redundant plate structures, which is convenient for the subsequent independent planning and layout of other electrical components.

[0024] For the outer packaging of the overall structure, the top and bottom of the outer frame 1 are respectively sealed by a top cover 20 and a bottom plate 21. The power supply layer 5 is arranged at an interval from the bottom plate 21. The two ends of the top layer 12 and the two ends of the interval between the power supply layer 5 and the bottom plate 21 are respectively sealed by an outer sealing plate 22. Through the design of the outer sealing plates 22 corresponding to the upper and lower parts, the overall flatness of the side surface of the outer frame 1 is higher, which is beneficial to the subsequent overall outer packaging of the product.

[0025] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
