Outdoor power distribution cabinet for factory electrical control system

Abstract

The invention discloses an outdoor power distribution cabinet for a factory electrical control system and belongs to the field of power distribution cabinet equipment. The outdoor power distribution cabinet for the factory electrical control system comprises a power distribution cabinet body. The front and back ends of the power distribution cabinet body are provided with a plurality of uniformly-distributed bar-shaped radiating holes. Each bar-shaped radiating hole is internally and fixedly connected with a matched nanometer dustproof net. The upper side of each bar-shaped radiating hole is provided with a matched rain baffle plate, and the rain baffle plate is fixedly connected to the side wall of the power distribution cabinet body. The front and back sides of the power distribution cabinet body are respectively provided with a driven gear plate. The upper end of each driven gear plate is engaged by a driving gear. The power distribution cabinet body is internally and fixedly connected with a pair of positive and negative rotating motor bodies. The front and back ends of the power distribution cabinet body are also respectively provided with a rotation hole. By adjusting the radiating holes of the power distribution cabinet, and arranging the filter net to prevent the dusts in the factory and automatically cleaning the radiating holes regularly to maintain the heat dissipation performance, the power distribution cabinet is allowed to have dual functions of heat dissipation and dust blocking.

Description

technical field [0001] The invention relates to the field of power distribution cabinet equipment, and more specifically relates to an outdoor power distribution cabinet used in factory electrical control systems. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is 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] ...

AI Technical Summary

Problems solved by technology

[0003] The electrical control system of the factory is generally more complicated, and outdoor power distribution cabinets are often used for power distribution. However, the outdoor power distribution cabinets face a complex external environment, and most of the factories are dusty, and the electronics inside the power distribution cabinets Components will emit a lot of heat during operation. It is inevitable that the power distribution cabinet needs to be equipped with heat dissipation holes to exchange heat with the outside air. This is because the dust in the factory can easily enter the interior of the power distribution cabinet from the heat dissipation holes. On the one hand, it will Corrosion of electronic components shortens their service life. On the other hand, dust adhesion in the circuit will cause resistance changes, resulting in excessive current in the circuit or even short circuit, which seriously threatens the normal use of the power distribution cabinet and the operation of the factory electrical control system. Once the electrical control System downtime can result in significant production losses
