Description

Technical Field

[0001] This utility model relates to the field of power control cabinets, and in particular to a combined power control cabinet. Background Technology

[0002] Power control cabinets are crucial devices in power systems used for the centralized installation, protection, and management of various electrical equipment (such as circuit breakers, relays, and instruments). They are widely used in industrial production, building construction, and power distribution. Their main function is to achieve the orderly arrangement and connection of electrical equipment through a rational internal space layout, while also providing protection against external environmental factors (such as dust, moisture, and external impacts) that could interfere with equipment operation, thus ensuring the stability and safety of the power system.

[0003] In traditional power control cabinet designs, one or more mounting plates are typically fixed to the inner rear wall of the cabinet for easy equipment installation and fixation. Various electrical devices are directly mounted on these mounting plates using bolts and other connectors. However, traditional power control cabinets often employ a one-piece structure, with all four sides of the cabinet being enclosed walls, allowing operation and observation of the internal equipment only through the front door. This structure has significant limitations in practical use: due to the cabinet's inherent depth, when electrical equipment mounted on the rear mounting plate malfunctions and requires repair, the walls on the left, right, top, and bottom of the cabinet create space constraints, hindering maintenance personnel from reaching in, operating tools, and observing equipment details. Especially for equipment located deep within the cabinet or in corners, maintenance personnel often have to work in confined spaces, increasing repair difficulty, extending repair time, and potentially leading to incomplete repairs due to operational limitations, thus affecting the subsequent operational stability of the electrical equipment. Therefore, this application proposes a modular power control cabinet to address these issues. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5As shown, a modular power control cabinet includes a main body 1. A detachable back panel assembly 4 is detachably installed on the main body 1. The detachable back panel assembly 4 consists of a control cabinet back panel 13, an equipment mounting plate 14, a support plate 15, and mating rods 16. The equipment mounting plate 14 is fixedly installed at the front end of the control cabinet back panel 13. There are two support plates 15, which are symmetrically fixedly installed at the left and right ends of the control cabinet back panel 13. There are two mating rods 16, which are respectively fixedly installed at the outer ends of the two support plates 15. Four limiting structures 2 are symmetrically fixedly installed at the left and right ends of the main body 1. The limiting structure 2 consists of a mounting square rod 6, a fixing spring 7, and an anti-detachment baffle 8. The fixing spring 7 is sleeved on the mounting square rod 6, and the anti-detachment baffle 8 is fixedly installed at the outer end of the mounting square rod 6. A fixing structure 3 is installed on two adjacent limiting structures 2. The fixing structure 3 consists of a mounting base plate 9, an L-shaped connecting plate 11, and a fixing pin 12. There are two L-shaped connecting plates 11, which are symmetrically fixedly installed at the rear end of the mounting base plate 9. There are two fixing pins 12, which are respectively fixedly installed at the rear end of the mounting base plate 9. The back panel assembly 12 is fixedly installed at the inner ends of the two L-shaped connecting plates 11, and the fixing pin 12 is simultaneously embedded in the mating rod 16. By setting a detachable back panel assembly 4 composed of a control cabinet back panel 13, an equipment mounting plate 14, a support plate 15, and a mating rod 16, the detachable back panel assembly 4 can be separated from the main body 1 of the power control cabinet. When the power equipment on the equipment mounting plate 14 malfunctions and needs maintenance, the main body 1 of the power control cabinet can be removed, so that the equipment installed on the equipment mounting plate 14 is completely freed from the space restriction of the main body 1 of the power control cabinet. Thus, this modular power control cabinet allows maintenance personnel to operate more conveniently and improve maintenance efficiency. By setting a limiting structure 2 composed of a mounting square rod 6, a fixing spring 7, and an anti-detachment baffle 8, and a fixing structure 3 composed of a mounting base plate 9, an L-shaped connecting plate 11, and a fixing pin 12, the main body 1 of the power control cabinet and the detachable back panel assembly 4 are connected together through the limiting structure 2 and the fixing structure 3. This facilitates the disassembly and assembly of the main body 1 of the power control cabinet and the limiting structure 2, thereby further facilitating the installation, maintenance, and replacement of the equipment.

[0022] Specifically, a protective door 5 is installed at the front end of the main body 1 of the power control cabinet. A through groove 18 is opened on the rear side wall of the main body 1 of the power control cabinet. The control cabinet back plate 13 on the detachable back plate assembly 4 is attached to the rear end of the main body 1 of the power control cabinet. The equipment mounting plate 14 passes through the through groove 18 from back to front and is inserted into the main body 1 of the power control cabinet. Two support plates 15 on the detachable back plate assembly 4 are located on the left and right sides of the main body 1 of the power control cabinet, and the two support plates 15 are in contact with the left and right ends of the main body 1 of the power control cabinet. Two fixing slots 17 are symmetrically opened on the outer end of the mating rod 16. The mounting square rod 6 on the limiting structure 2 is fixedly installed on the end face of the main body 1 of the power control cabinet. One end of the fixing spring 7 is also fixedly installed on the end face of the main body 1 of the power control cabinet. Two mounting square holes 10 are symmetrically opened on the mounting base plate 9 on the fixing structure 3. The mounting base plate 9 is movably sleeved on the mounting square rod 6 on the limiting structure 2 through the mounting square holes 10. The inner end of the mounting base plate 9 is fixedly connected to one end of the fixing spring 7. The 12 is embedded in the fixed slot 17. When in use, the combined power control cabinet needs to be installed in the designated position. The method is to pass the bolt through the control cabinet back plate 13 on the detachable back plate assembly 4 and install the bolt into the threaded hole set in the designated position. At this time, the installation of the combined power control cabinet is completed. When it is necessary to repair the power equipment installed on the equipment mounting plate 14, in order to facilitate the maintenance operation of the staff, the main body 1 of the power control cabinet can be removed from the detachable back plate assembly 4. At this time, first pull the mounting base plate 9 outward, so that the mounting base plate 9 will move outward along the mounting square rod 6 and stretch the fixing spring 7. At this time, the fixing pin 12 will move outward with the L-shaped connecting plate 11 and disengage from the fixed slot 17. Then, the main body 1 of the power control cabinet can be moved forward, so that the equipment mounting plate 14 is passively pulled out from the through slot 18, thereby completing the removal of the main body 1 of the power control cabinet from the detachable back plate assembly 4. Then, the power equipment installed on the equipment mounting plate 14 can be easily repaired.
