Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an expandable combined power distribution cabinet. Background Technology

[0002] Distribution cabinets are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. They are the control center that directs the rational distribution of electrical energy among various components in the power supply line, and are the control link that reliably receives the upstream power supply and can correctly feed back the load electrical energy.

[0003] Common distribution cabinets typically use modular mounting brackets for installation. Generally, this involves installing support brackets on both sides inside the cabinet, with multiple mounting holes on each bracket. Then, horizontal support brackets are installed in the corresponding mounting holes according to the actual needs. After installation, circuit breakers and other modules are then mounted on the support brackets. However, the support brackets are usually fixed with screws and cannot be adjusted after fixing. When temporary expansion of modules is needed, if the space is not planned in advance, the vertical space may not be used well, resulting in insufficient space to install the module. This can lead to situations where the existing space is insufficient to install the module, requiring fine-tuning of the vertical space to install it. Utility Model Content

The sliding plate 212 has a threaded rod 213 in the middle. The top of the threaded rod 213 passes through the top of the mounting groove 211, and one bottom end of the threaded rod 213 is rotatably connected to the bottom of the mounting groove 211. The end face of the sliding plate 212 has multiple connecting rods 214. The front end of the mounting groove 211 has a slide rail 216 that matches the number of connecting rods 214. One end of the connecting rod 214 passes through the slide rail 216 and is mounted with a fixing bracket 215. The fixing bracket 215 is mounted on the front end face of the mounting plate 21.

[0028] Specifically, mounting brackets 15 are bolted to both sides of cabinet 11. Then, multiple horizontal expansion brackets 2 are installed on the mounting brackets 15 on both sides of cabinet 11. The mounting brackets 15 have multiple holes for installing the horizontal expansion brackets 2. Then, a fixing bracket 215 is installed at the front end of the horizontal expansion bracket 2. This allows modules such as circuit breakers to be installed on the fixing bracket 215. When connecting wires to the upper and lower ends of the circuit breaker modules, the wires need to be bent into an n-shape to leave some space so that the wires will not be pulled when adjustments are needed later. During the adjustment process, the sliding plate 212 can be moved up and down in the mounting slot 211 by rotating the threaded rod 213.
