Problems solved by technology

[0003] There are many incoming and outgoing cables in the current power distribution cabinet, so the existing power distribution cabinet looks very messy, and it is difficult to quickly find the position of the corresponding cable. Although this kind of power distribution cabinet can be installed with internal components, but due to the The position cannot be adjusted. If the size of the installed internal components changes, it will be difficult to meet the installation requirements. Additional lighting equipment is required to provide light when repairing or replacing lines, which is very inconvenient

Abstract

The invention discloses a power distribution cabinet with high heat dissipation performance. The power distribution cabinet comprises a power distribution cabinet body, an indicator lamp is fixedly connected to the top of a cabinet door handle, an ampere meter is fixedly connected to the top of the indicator lamp, a power distribution cabinet top cover is movably connected to the top of a power distribution cabinet door, a U-shaped connecting plate is movably connected to the left side of a partition plate, and a second electric appliance element containing groove is formed in a second electric appliance element mounting plate. According to the power distribution cabinet with high heat dissipation performance, a worker can adjust the position of the partition plate according to the workingrequirement, so that the mounting requirement is met, a small lighting bulb is arranged, lighting can be provided for a maintainer, the maintainer does not need to additionally hold other lighting devices, maintenance is facilitated, and the working efficiency of the worker is improved. A waterproof breathable film is arranged on a breathable waterproof filter screen, the tensile strength and themoisture permeability of the waterproof breathable film are far higher than those of the waterproof breathable film in the prior art, the heat dissipation performance of the power distribution cabinet can be better improved, and then safe operation of the power distribution cabinet is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high heat dissipation power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Power distribution cabinets are collectively referred to as motor control centers. , The motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control for the load. The power distribution cabinet is referred to as JP cabinet, with the continuous deepening of rural and urban power grid transformation, a large number of power distribution cabinets are used in po...
