Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, in particular to a combined distribution cabinet which is convenient for installation and maintenance. Background Art

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively scattered and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large; they distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. Generally, electrical components such as leakage switches, air switches, universal circuit breakers, current transformers, voltage transformers, ammeters, and voltmeters are configured in the distribution cabinet. After the distribution box is manufactured, its structure is fixed. When subsequent electrical components need to be expanded, the distribution box cannot be expanded, resulting in the need to replace the new distribution box; the electrical components in the original distribution box need to be disassembled and reinstalled; in addition, the arrangement positions of the electrical components in the distribution box are fixed. When maintenance personnel perform maintenance work on some electrical components, they are easily blocked by other electrical components in the distribution box, affecting the maintenance work.

[0027] Reference Figures 1-6 , an embodiment of the present application shows a combined power distribution cabinet which is convenient for installation and maintenance, including at least two sub-cabinet units 1 spliced side by side; the sub-cabinet unit 1 includes a sub-frame 11, the sub-frame 11 includes two four-side frame type structures 111 arranged up and down, and four square vertical rods 112 are connected between the two four-side frame type structures 111. The four vertical rods 112 are distributed in a matrix. Horizontal splicing holes 1121 are respectively arranged on two mutually perpendicular outer sides of the vertical rods 112. The sub-frames 11 of the two sub-cabinet units 1 are spliced by passing bolt assemblies through the splicing holes 1121; the sub-cabinet unit 1 further includes a wall plate 12 and a cabinet door 13 arranged outside the sub-frame 11. The wall plate 12 is fixed on the sub-frame 11 by connecting the splicing holes 1121 through bolt assemblies. The cabinet door 13 is hinged to the sub-frame 11 through a hinge (not shown), and the hinge is connected to the splicing holes 1121 through bolt assemblies.

[0028] Specifically, the wall panel 12 and the cabinet door 13 are both detachably connected to the sub-frame 11. When splicing and expanding are required, only the wall panel 12 or the cabinet panel on the corresponding side of the sub-frame 11 needs to be removed, then the new sub-frame 11 is brought together, and then the bolt assembly is used to pass through the splicing holes 1121 of the two sub-frames 11 to achieve the fixed connection between the two sub-frames 11. In this way, the capacity of the combined power distribution cabinet is expanded. It is not necessary to completely disassemble and reinstall all the electrical components originally installed inside the combined power distribution cabinet. Only the installation positions of some electrical components need to be adjusted according to the requirements of the new electrical component configuration, and some electrical components are added, effectively reducing the workload.

[0029] In some embodiments, as Figures 4-6 shown, a plurality of mounting cross-beams 113 are provided inside the sub-frame 11. Vertical wing plates 1122 are provided on the inner side surfaces of the vertical rods 112. A plurality of first connection holes 1123 are provided on the wing plates 1122 at intervals in the vertical direction. Both ends of the mounting cross-beam 113 are respectively connected to the first connection holes 1123 on the two vertical rods 112 through bolt assemblies. A guide groove 1131 is transversely provided on the mounting cross-beam 113. A mounting plate 114 is slidably connected to the guide groove 1131. A positioning mechanism is provided between the mounting plate 114 and the mounting cross-beam 113 to fix the position of the mounting plate 114 on the mounting cross-beam 113.

[0030] In this embodiment, the electrical components are installed on the mounting plate 114, and the mounting plate 114 can horizontally adjust its position on the mounting cross-beam 113. At the same time, the mounting cross-beam 113 can vertically adjust its position on the sub-frame 11, so as to realize the position adjustment of the electrical components in a vertical plane inside the power distribution cabinet. When configuring according to the requirements of the new electrical component configuration, the installation workload can be reduced, and the position of the electrical components can be adjusted during maintenance to avoid hindering the operation of the maintenance personnel.

[0031] Specifically for the above solution, to facilitate the horizontal movement of the mounting plate 114 on the mounting cross-beam 113, as Figure 6 shown, a sliding member 1142 is provided on the back of the mounting plate 114. The guide groove 1131 is in the shape of a dovetail groove. The outer contour of the sliding member 1142 matches the shape of the guide groove 1131, and the sliding member 1142 is slidably arranged in the guide groove 1131.

[0032] Specifically for the above solution, to facilitate the fixation of the mounting plate 114 after adjusting its position on the mounting cross-beam 113, refer to Figure 5 and Figure 6, a plurality of second connection holes 1132 arranged at intervals in the transverse direction are provided on the mounting cross beam 113, a positioning hole 1141 is provided on the mounting plate 114, and the positioning mechanism includes a plug pin 115. The plug pin 115 is inserted into the positioning hole 1141 and the second connection hole 1132 to fix the position of the mounting plate 114 on the mounting cross beam 113. For ease of manufacturing, the plug pin 115 can be a bolt; when the transverse position of the mounting plate 114 needs to be adjusted, only the plug pin 115 needs to be pulled out, and the operation is simple.

[0033] In some embodiments, referring to Figure 1 and Figure 2 , moving wheels 14 are provided at the bottom of the sub-cabinet unit 1. In this way, it is convenient to move the sub-cabinet unit 1, facilitate the splicing operation, and facilitate the transportation of the power distribution cabinet.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
