Problems solved by technology
[0003] (1) The power distribution cabinet of the prior art only has one installation bracket in the cabinet, and all electrical components are only installed on this installation bracket, and the installation area is small. In order to install more electrical components, the power distribution cabinet needs to be made The longer and higher the power distribution cabinet, the larger the volume;
[0004] (2) When performing maintenance, maintenance personnel must enter the interior of the power distribution cabinet to overhaul the electrical components and lines, and the space is limited; due to the height of the power distribution cabinet, the electrical components at a high place also cause inconvenience for maintenance; in power distribution The space in the cabinet is limited, and the electrical components and lines are relatively dense, which will also cause inconvenience to maintenance;
[0005] (3) The long-term operation of the power distribution cabinet causes the internal problem of the box to be too high and it is difficult to dissipate heat. In the prior art, vents or fans are usually installed on the power distribution cabinet to solve the heat dissipation problem, but a large number of power distribution modules Installed in a large space in the cabinet, the heat between the power distribution modules will be transferred to each other, resulting in relatively concentrated heat, and it is difficult to dissipate heat, and it is difficult for the external airflow to take away the internal heat

The invention discloses a power distribution cabinet convenient for heat dissipation and maintenance. The cabinet comprises a bottom plate which is horizontally arranged and is in the shape of a regular polygon, and supporting legs are disposed below the bottom plate. A hollow wire pipe is arranged at each corner of the bottom plate, a top plate is arranged between the upper ends of the pluralityof wire pipes, each wire pipe is rotatably connected with a sleeve, the outer side of each sleeve extends to form a cabinet plate, the cabinet plates are used for installing electrical elements, and each cabinet plate is provided with a first air hole. A rotating shaft is rotationally connected to the center of the bottom plate, a rotating disc is arranged at the upper end of the rotating shaft, aplurality of vertical plates are arranged on the upper surface of the rotating disc, a cover plate is arranged between the upper ends of the vertical plates, a convex column rotationally connected tothe top plate is arranged at the center of the cover plate, and second air holes are formed in the convex column and the top plate in the vertical direction. A first power assembly is arranged belowthe bottom plate. A second power assembly is arranged on the top plate. The power distribution cabinet is simple in structure, high in heat dissipation efficiency and convenient to maintain.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet that is convenient for heat dissipation and maintenance. Background technique [0002] The power distribution cabinet is a common power supply control equipment. Its main purpose is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed metal cabinet according to the requirements of electrical wiring, so as to meet the requirements of normal operation of the power system without endangering people and surroundings. Equipment Security. The existing power distribution cabinets have the following problems during use: [0003] (1) The power distribution cabinet of the prior art only has one installation bracket in the cabinet, and all electrical components are only installed on this installation bracket, and the installation area is small. In order to install more electrical components...
