Power distribution cabinet with high dustproof and heat radiation performance

Abstract

The invention discloses a power distribution cabinet with high dustproof and heat radiation performance. The power distribution cabinet comprises a main cabinet body and a driving motor. The driving motor is fixedly connected with the top of one outer wall at one side of the main cabinet. The inner top of the main cabinet is provided with a ventilating opening. The output end of the driving motorpenetrates through the external wall of the main cabinet body and extends in the ventilating opening. A gear fixedly sleeves the extending end of the driving motor. A gear tooth frame sleeves the gear. The gear tooth frame is internally provided with gear teeth which engage with the gear. The ventilating opening is internally and fixedly connected with a slide bar. A slide block slidably sleeves the slide bar. The top of the slide block is fixedly connected with the gear tooth frame. The bottom of the slide block is fixedly connected with an electric fan. The inner bottom of the main cabinet body is provided with a plurality of circular holes which correspond with the electric fan. According to the power distribution cabinet, through arranging the movable electric fan and a dustproof net,heat radiation capability and dustproof capability in the power distribution cabinet are effectively improved, thereby effectively preventing burndown of inner electric components in the power distribution cabinet because of overhigh temperature.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a power distribution cabinet with strong dustproof and heat dissipation performance. 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. [0003] However, the internal structure of the existing power distribution cabinet is relatively simple, and there is a lack of heat dissipation and dust-proof mecha...
