Self-bunching type moisture-proof power distribution cabinet

Abstract

The invention discloses a self-bunching type moisture-proof power distribution cabinet, and belongs to the technical field of electrics. According to the invention, the outside air humidity can be sensed by embedding a plurality of bunching balls in strip-shaped heat dissipation holes; when air entering a temporal part of a power distribution cabinet body is more humid, moisture-absorbing magnetic balls on the bunching balls can show a magnetic field after absorbing moisture, so the moisture-absorbing magnetic balls on the bunching balls and the moisture-absorbing magnetic balls on the adjacent bunching balls are mutually adsorbed and close to each other, gap areas between the bunching balls are filled, a plurality of moisture intercepting layers are formed, and the moisture in the air is effectively intercepted; after the air is dried, the magnetic field is weakened, then the moisture absorption magnetic balls are mutually separated and reset, and smoothness and heat dissipation performance of the strip-shaped heat dissipation holes are restored again; compared with an existing power distribution cabinet, heat dissipation can be achieved, bunching interception can be conducted on moisture at the same time, and the operation safety of electronic devices in the power distribution cabinet body is improved.

Description

technical field [0001] The invention relates to the field of electrical technology, and more specifically, relates to a self-bundling moisture-proof 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), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. 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 shall provide protection, monitoring and control of the load. [0003] The microcomputer pro...

Problems solved by technology

[0004] Although the heat dissipation holes help the power distribution cabinet to dissipate heat, but the characteristics of direct connection with the outside world, once the external environment is relatively humid, when the air with moisture enters the power distribution cabinet, it is easy to affect or even corrode the electronic devices The danger of reducing the reliability of the normal operation of the power distribution cabinet
