[0037] Embodiment 1

[0038] This embodiment provides a DC control cabinet with a functional partition structure, as shown in the attached Figures 1 - 5As shown, it includes:

[0039] Cabinet body 11 is provided with a receiving cavity 111. The cabinet body 11 includes a front cabinet door 112, a left side plate 113, a right side plate 114, a rear side plate, a bottom plate and a top plate. Several components are respectively arranged in six directions of front, back, left, right, up and down, and they cooperate to form the receiving cavity 111. In this embodiment, the front cabinet door 112 can be opened or closed relative to the cabinet body 11. Here, the front cabinet door 112 and the cabinet body 11 can be rotatably connected or in other connection ways. The receiving cavity 111 accommodates a number of components 12, and the components 12 can include a switching power supply 121, a dual power switch 122, a surge protector 123, and a main switch 124. The switching power supply 121, the dual power switch 122, the surge protector 123, and the main switch 124 cooperate to form an electrical circuit to achieve the effect of auxiliary control. In addition, the components 12 can also be miniature circuit breakers, etc. The components 12 face the side of the front cabinet door 112. Specifically, it refers to the operation area of the components 12 facing the side of the front cabinet door 112. Opening the front cabinet door 112 can perform the corresponding operations on the components 12. On both sides of the receiving cavity 111, there are respectively a first secondary terminal compartment 13 and a second secondary terminal compartment 14. The first secondary terminal compartment 13 is located on the left side of the receiving cavity 111, that is, the first secondary terminal compartment 13 is arranged on the left side plate 113. The second secondary terminal compartment 14 is located on the right side of the receiving cavity 111, that is, the second secondary terminal compartment 14 is arranged on the right side plate 114. Both the first secondary terminal compartment 13 and the second secondary terminal compartment 14 are provided with secondary terminal blocks 15 and secondary wiring grooves 16, and the voltages of the electrical circuits formed by the first secondary terminal compartment 13 and the second secondary terminal compartment 14 are different. In this embodiment, the voltage of the electrical circuit formed by the first secondary terminal compartment 13 is DC24V, and the voltage of the electrical circuit formed by the second secondary terminal isolation is AC220V. In addition, those skilled in the art can adjust according to actual needs. The voltages of the electrical circuits formed by the two secondary terminal compartments can both be direct current or both be alternating current. The voltages of the two can be combined as 220V and 12V, or can be combined as 220V and 36V. Those skilled in the art can adjust according to actual needs. With this structural setting, by arranging the two secondary terminal compartments in a left-right distribution, different distributions of the secondary terminal blocks 15 are formed, and by setting different voltages corresponding to different partition areas, different functional control effects are formed, avoiding faults caused by incorrect wiring due to different voltages; secondly, the components 12 and the secondary wiring are respectively placed in different positions, with clear function identification and convenient installation and maintenance. In this embodiment, different voltages are combined with different components to form different functional cooperation effects.

[0040] Specifically, as shown in the appendix Figures 1 - 5As shown, the secondary wiring duct 16 forms a number of chambers 161, and guide rails 162 are fixed in the chambers 161. The secondary terminal block 15 cooperates with the guide rails 162. Here, the secondary terminal block 15 is provided with slots that cooperate with the guide rails 162. Here, the guide rails 162 can be of a U-shaped structure or a G-shaped structure. The secondary wiring duct 16 forms a number of chambers 161, achieving a fixed effect for the secondary terminal blocks 15 with different functions, forming a refined layout. The secondary terminal blocks 15 with different functions correspond to different chambers 161, further improving the convenience of installation and maintenance. In addition, the secondary wiring duct 16 can also be in a frame shape, and the secondary terminal block 15 is directly fixed on the left side plate 113 or the right side plate 114, such as by pasting or bolt connection.

[0041] Specifically, as shown in the appendix Figures 1 - 5 As shown, the secondary wiring duct 16 includes a vertical wiring duct 163 and a horizontal wiring duct 164. The horizontal wiring duct 164 is perpendicularly connected to the vertical wiring duct 163 and is in communication with the vertical wiring duct 163. The secondary wiring duct 16 forms a connection and cooperation for the cables through the perpendicular connection. In this embodiment, for example, the first secondary terminal compartment 13 includes two vertical wiring ducts 163 and a number of horizontal wiring ducts 164. The two vertical wiring ducts 163 are arranged in parallel and are perpendicular to the horizontal plane. One end of the horizontal wiring duct 164 is perpendicularly connected to one of the vertical wiring ducts 163, and the other end of the horizontal wiring duct 164 is perpendicularly connected to the other vertical wiring duct 163. Therefore, a part of the two horizontal wiring ducts 164 and the two vertical wiring ducts 163 forms a chamber 161. Here, the structure of the second secondary terminal compartment 14 is similar, with the only difference being the size of the chamber 161. In addition, a connection effect can also be formed through an oblique cooperation method.

[0042] Specifically, wire duct covers 165 are fixed on both the vertical wiring duct 163 and the horizontal wiring duct 164. The setting of the wire duct covers 165 achieves a protective effect, protecting the cables or wires placed in the secondary wiring duct 16.

[0043] Specifically, the secondary terminal blocks 15 have different shapes, colors, or markings. The secondary terminal blocks 15 with the same shape, color, or marking are connected to the live wire of the same electrical circuit; or, the secondary terminal blocks 15 with the same shape, color, or marking are connected to the neutral wire of the same electrical circuit; or, the secondary terminal blocks 15 with the same shape, color, or marking are connected to the ground wire of the same electrical circuit. The live wire, neutral wire, and ground wire correspond to different shapes, colors, or markings, forming a distinguishing effect, enabling the operator to wire according to the corresponding shape, color, or marking to prevent incorrect wiring. For example, in this embodiment, the color of the secondary terminal block 15 corresponding to the live wire is gray, the color of the secondary terminal block 15 corresponding to the neutral wire is green, and the color of the secondary terminal block 15 corresponding to the ground wire is yellow, forming the distinction of different circuits through color differentiation. It should be noted here that since the attached drawings are black-and-white line drawings, the colors cannot be visually reflected, but those skilled in the art should know how to distinguish the secondary terminal blocks 15 by color. Those skilled in the art can also form the distinction of different circuits by changing the shape or marking. Compared with the prior art where the wiring diagram is referred to and then the colors of the wires or cables are used for differentiation, there is still a possibility of incorrect wiring. The differentiation method in this embodiment is more obvious. By combining the secondary terminal blocks 15 with the wires, it is more difficult to connect the wires incorrectly, and the operator can achieve electrical connection without referring to the drawing.

[0044] Specifically, as shown in the Figures 1 - 5 accompanying drawings, it further includes an auxiliary power supply module 17. The auxiliary power supply module 17 is accommodated in the accommodation cavity 111, and the components 12 are all arranged on the auxiliary power supply module 17. The switching power supply 121, double power switch 122, surge protector 123, and main switch 124 form a part of the auxiliary power supply module 17. A DC busbar module 18 is also included. The DC busbar module 18 is accommodated in the accommodation cavity 111. The auxiliary power supply module 17 and the DC busbar module 18 are distributed vertically in the accommodation cavity 111. In this embodiment, the auxiliary power supply module 17 is located above the DC busbar module 18. With this structural arrangement, through the layout design, the two modules do not interfere with each other, ensuring normal functional use. Moreover, after combination, the space of the prefabricated warehouse is saved, providing more space for the installation of more control circuits, improving the dynamic loop monitoring and data acquisition effects of the DC control cabinet on the prefabricated warehouse. Through the vertical distribution setting, the overall layout is more perfect and the operation is more convenient.

[0045] Specifically, as shown in the Figure 5 accompanying drawings, it further includes a communication module 19. The communication module 19 is accommodated in the accommodation cavity 111. Here, the communication module 19 is specifically fixed on the front cabinet door 112 and is specifically located on the front side of the auxiliary power supply module 17. The layout distribution of the three modules improves the overall space utilization rate, thereby saving the space of the prefabricated warehouse and providing more space for battery expansion to increase the capacity.

[0046] Specifically, the auxiliary power supply module 17 includes a fixing plate 171, and the components 12 are fixed on the fixing plate 171. The switching power supply 121, the dual power switch 122, the surge protector 123, and the main switch 124 are fixedly connected to the fixing plate 171. A fixing rail can also be provided on the fixing plate 171 here.

[0047] Specifically, the DC busbar module 18 includes a disconnecting switch 181 and a UPS 182. A first partition plate 183 is provided between the disconnecting switch 181 and the UPS 182. The setting of the first partition plate 183 increases the isolation effect between the disconnecting switch 181 and the UPS 182.

[0048] Specifically, the DC busbar module 18 includes a plurality of busbars 184, and the busbars 184 are arranged in a staggered manner up and down or in a staggered manner front and back. The staggered arrangement of the busbars 184 increases the electrical clearance between two adjacent busbars 184. At the same time, it also makes the wiring more convenient. Here, the front and back staggering specifically means that the distances from the front cabinet door 112 are different, and the up and down staggering means in the vertical height direction. The distance between the left and right can be adjusted according to actual needs.

[0049] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
