[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present application provides a power distribution device, whose structure includes a power distribution cabinet 1, a main circuit breaker 2 and a plurality of branch circuit breakers 3 arranged in the power distribution cabinet 1, and a switch 4 is also arranged in the power distribution cabinet 1, and the switch 4 is used to collect information and exchange information between the main circuit breaker 2 and the branch circuit breaker 3.

[0029] In actual use, information exchange is performed between the main circuit breaker 2 and the branch circuit breaker 3 through the switch 4 .

[0030] In the above design, the switch 4 is provided to realize the real-time information interaction of the branch circuit breaker 3 of the main circuit breaker 2, thereby improving the information interaction efficiency of the main circuit breaker 2 and the branch circuit breaker 3.

[0031] Specifically: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the power distribution cabinet 1 includes a box body 11, a partition frame 13 arranged in the box body 11, and an inner and outer double-door mechanism 12 arranged on the box body 11. The partition frame 13 and the box body 11 form two adjacent accommodating cavities No. 1 and No. 2 on the left and right. The No. 1 accommodating cavity is provided with a No. 1 mounting rail 5 for installing the main circuit breaker 2 and a No. 2 mounting rail 6 for installing the switch 4. The No. 2 accommodating cavity is provided with a No. 3 mounting rail 7 for installing the branch circuit breaker 3.

[0032] In actual use, the main circuit breaker 2 is installed on the first mounting rail 5, the switch 4 is installed on the second mounting rail 6, and the branch circuit breaker 3 is installed on the third mounting rail 7. The main circuit breaker 2 and the branch circuit breaker are respectively in the first accommodating cavity and the second accommodating cavity.

[0033] In the above design, the box body 11 forms two accommodating chambers by arranging a partition, which can ensure effective isolation between the main circuit breaker 2 and the branch circuit breaker 3 and isolate the heat transfer between the main circuit breaker 2 and the branch circuit breaker 3.

[0034] Specifically: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inside-outside double-door mechanism 12 includes a left outer panel 121 connected to the left hinge of the box body 11, a right outer panel 122 connected to the right hinge of the box body 11, a left inner panel 123 connected to the left hinge of the box body 11, and a right outer panel 122 connected to the right hinge of the box body 11. The left outer panel 121 and the right outer panel 122 can both be closed with the partition frame 13, and the left inner panel 123 and the right inner panel 124 can both be closed with the partition frame 13. After closing, the left inner panel 123 is located on the inner side of the left outer panel 121, and the right inner panel 124 is located on the inner side of the right outer panel 122.

[0035] In actual use, after the main circuit breaker 2, the branch circuit breaker 3 and the switch 4 are assembled and adjusted to the working state, the left inner plate 123 and the right inner plate 124 are closed, and then the left outer plate 121 and the right outer plate 122 are closed. When it is necessary to replace the equipment in the power distribution cabinet 1, it is necessary to open the left outer plate 121 and the right outer plate 122 first, and then open the right inner plate 124 and the left inner plate 123.

[0036] In the above design, the structural design and specific implementation method of the double-door mechanism can effectively protect the equipment in the box 11.

[0037] Specifically: Figure 3 As shown, the branch circuit breaker 3 includes an electrical module and a switch electrically connected to the electrical module, the right inner plate 124 is provided with a No. 1 through hole corresponding to the switch one by one, the left inner plate 123 is provided with a No. 2 through hole corresponding to the operation page of the main circuit breaker 2, and the inner side of the left inner plate 123 is also provided with an air switch module connected to the switch 4, and the left inner plate 123 is also provided with a No. 3 through hole corresponding to the air switch module, so that the operating end of the air switch module is located on the outer side of the left inner plate 123, and when the right inner plate 124 and the left inner plate 123 are closed, the operating ends of the switch, the air switch module and the operation page of the main circuit breaker 2 protrude from the No. 1 through hole, the No. 3 through hole and the No. 2 through hole respectively, and do not contact the right outer plate 122 and the left outer plate 121 in the closed state.

[0038] In actual use, when the inner and outer double door mechanism 12 is in the closed state, the electrical module is located in the No. 2 accommodation chamber inside the right inner plate 124. When the branch circuit breaker 3 needs to be adjusted, the right outer plate 122 is opened, and the switch protruding from the No. 1 through hole is directly adjusted while the right inner plate 124 is kept closed. When the main circuit breaker 2 or the switch 4 needs to be adjusted, the left outer plate 121 is opened, and the left inner plate 123 is kept closed, and the operation page of the main circuit breaker 2 protruding from the No. 2 through hole is directly operated to adjust the main circuit breaker 2, and the operation end of the air switch module protruding from the No. 3 through hole is operated to open and close the air switch module.

[0039] In the above design, since the electrical module is isolated by the right outer plate 122, the operator can avoid touching the electrical module part that may cause personal injury when adjusting the branch circuit breaker 3, which effectively improves safety. In addition, the air switch module of the switch 4 is set on the left inner plate 123 and can rotate with the left inner plate 123, which is convenient for maintenance of the switch 4.

[0040] Specifically: Figure 3 and Figure 5 As shown, the No. 1 mounting rail 5, the No. 2 mounting rail 6 and the No. 3 mounting rail 7 have the same structure, the No. 1 mounting rail 5 includes a vertical plate 51, an upper horizontal plate 52 arranged at the upper end of the vertical plate 51 and a lower horizontal plate 53 arranged at the lower end of the vertical plate 51, the vertical plate 51, the upper horizontal plate 52 and the lower horizontal plate 53 form a mounting groove, the vertical plate 51 is provided with a plurality of mounting holes 510, and assembly holes matching the mounting holes 510 are vertically arranged on both sides of the box body 11 and the partition frame 13.

[0041] In actual use, taking the No. 1 mounting rail 5 as an example, the side of the main circuit breaker 2 is installed through the mounting groove to ensure that the side of the main circuit breaker 2 is located in the mounting groove, so that the lower horizontal plate 53 supports the main circuit breaker 2. When the height of the main circuit breaker 2 needs to be adjusted, the mounting hole 510 on the vertical plate 51 is aligned with the assembly hole at the corresponding height, and then the main circuit breaker 2 is fixed to the box body 11 and the partition frame 13 by passing the mounting hole 510 and the assembly hole with a locking member such as a bolt.

[0042] In the above design, the structural design and specific implementation method of the No. 1 mounting rail 5, the No. 2 mounting rail 6, and the No. 3 mounting rail 7 can effectively realize the installation of the main circuit breaker 2, the branch circuit breaker 3 and the switch 4, and can ensure the height adjustment of the main circuit breaker 2, the branch circuit breaker 3 and the switch 4.

[0044] In actual use, the switch 4 , the main circuit breaker 2 and the branch circuit breaker 3 will all emit a large amount of heat, and part of the heat will be discharged from the box body 11 through the heat dissipation holes 100 arranged in a honeycomb pattern.

[0045] In the above design, by providing heat dissipation holes 100 at the lower ends of the left inner plate 123 and the right inner plate 124, part of the heat in the No. 1 accommodating cavity and the No. 2 accommodating cavity can be discharged in time.

[0046] Specifically: Figure 2 and Figure 3 As shown, a fan 14 and a shutter 16 corresponding to the fan 14 are provided on the side of the box body 11 .

[0047] During actual use, the exhaust fan 14 draws air toward the outside of the box body 11 , so that the airflow in the box body 11 flows outward along the louver 16 .

[0048] In the above design, the exhaust fan 14 is used as a power source to accelerate the airflow in the box 11 to flow to the outside of the box 11, thereby increasing the speed and intensity of the airflow movement and ensuring that the heat in the box 11 is dissipated in time.

[0049] Specifically: Figure 1 and Figure 2 As shown, a plurality of lifting rings 110 are provided at the upper end of the box body 11 .

[0050] In actual use, the power distribution device of the present application is hoisted by connecting the hoist ring 110 through external hoisting equipment.

[0051] In the above design, by providing a lifting ring 110 on the box body 11 , rapid transfer of the power distribution cabinet 1 can be ensured.

[0052] Specifically: Figure 2 As shown, the switch 4 is located above the main circuit breaker 2 .

[0053] In the above design, the switch 4 is located above the main circuit breaker 2, which is convenient for operators to maintain.

The power distribution cabinet 1 includes a box body 11, a partition frame 13 arranged in the box body 11, and an inner and outer double-door mechanism 12 arranged on the box body 11, and the partition frame 13 and the box body 11 form two adjacent accommodating cavities No. 1 and No. 2, and the No. 1 accommodating cavity is provided with a No. 1 mounting rail 5 for installing the main circuit breaker 2 and a No. 2 mounting rail 6 for installing the switch 4, and the No. 2 accommodating cavity is provided with a No. 3 mounting rail 7 for installing the branch circuit breaker 3.

The left outer panel 121 and the right outer panel 122 can both be closed with the partition frame 13, and the left inner panel 123 and the right inner panel 124 can both be closed with the partition frame 13. After closing, the left inner panel 123 is located on the inner side of the left outer panel 121, and the right inner panel 124 is located on the inner side of the right outer panel 122. The branch circuit breaker 3 includes an electrical module and a switch electrically connected to the electrical module. The right inner plate 124 is provided with a No. 1 through hole corresponding to the switch one by one. The left inner plate 123 is provided with a No. 2 through hole corresponding to the operation page of the main circuit breaker 2. The inner side of the left inner plate 123 is also provided with an air switch module connected to the switch 4. The left inner plate 123 is also provided with a No. 3 through hole corresponding to the air switch module, so that the operation end of the air switch module is located on the outer side of the left inner plate 123. When the right inner plate 124 and the left inner plate 123 are closed, the switch, the operation end of the air switch module and the operation page of the main circuit breaker 2 protrude from the No. 1 through hole, the No. 3 through hole and the No. 2 through hole respectively, and do not contact the right outer plate 122 and the left outer plate 121 in the closed state.
