High-low voltage power distribution cabinet

Abstract

The invention discloses a high-low voltage power distribution cabinet, and relates to the technical field of power distribution cabinets. The high-low voltage power distribution cabinet comprises a high-low voltage power distribution cabinet body, heat dissipation holes corresponding in position are evenly formed in the lower ends of the left side and the right side of the high-low voltage power distribution cabinet body, and a case is fixedly installed on the back face of the high-low voltage power distribution cabinet body. According to the high-low voltage power distribution cabinet, through cooperation of the high-low voltage power distribution cabinet body, the heat dissipation holes, the first cleaning device and the second cleaning device, and the first cleaning device and the second cleaning device are used for cleaning holes of the heat dissipation holes, so the anti-blocking effect of the heat dissipation holes is achieved, the high-low voltage power distribution cabinet effectively solves the problem that the high-low voltage power distribution cabinet body is used for a long time, dust and particles block the heat dissipation holes, the heat dissipation holes are cleaned and dredged irregularly to achieve the internal heat dissipation effect of the high-low voltage power distribution cabinet body, and damage to electrical components caused by over-high temperature in the high-low voltage power distribution cabinet body due to blockage of the heat dissipation holes is avoided.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a high and low voltage power distribution cabinet. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final equipment of the power distribution system. Power distribution cabinets are collectively referred to as motor control centers. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; 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 nearest load. This level of equipment should provide protection, monitoring and control for the load. In production sites and offices with ...

Problems solved by technology

[0003] However, the existing high and low voltage power distribution cabinets are easy to block the gaps of the heat dissipation holes after long-term use by dust and particles. Cause the internal temperature of the high and low voltage power distribution cabinet to rise, and the internal temperature of the high and low voltage power distribution cabinet is too high, which will cause damage to the electrical components and shorten the service life of the electrical components; at the same time, the electrical components of the power distribution cabinet are directly exposed after the cabinet door is opened. In front of the maintenance personnel, the occurrence of accidents when the staff overhauls the electrical components increases
