Problems solved by technology

[0003] In order to improve the service life of the power distribution cabinet, it is usually chosen to install a protective device for the power distribution cabinet. However, the existing protective device for the power distribution cabinet has a single structure, and most of them are a single protective box. Several cooling channels are installed on the protective box. Holes, heat dissipation through natural wind, there is a problem of poor heat dissipation, and then reduce the service life of components in the power distribution cabinet, based on this, we propose a power distribution cabinet protection device with heat dissipation function to solve the above problems

Embodiment 1

[0026] see Figure 1-6 , a protective device for a power distribution cabinet with a heat dissipation function, comprising a protective box 1 and a box door 2 with damping and rotatingly installed on the protective box 1, the side wall of the protective box 1 is provided with several In the ventilation hole 3 for heat dissipation, a dynamic heat dissipation component is provided on the side wall of the protective box 1, and a U-shaped limit seat 4 is fixedly installed on the side wall of the protective box 1. The dynamic heat dissipation component includes a cooling fan 5. A heat dissipation motor 6 for driving the heat dissipation fan 5 to rotate, a swing assembly and a lifting assembly for driving the heat dissipation fan 5 to move, and the heat dissipation motor 6 is arranged on the swing assembly;

[0027] The swing assembly includes an L-shaped fixing seat 7 fixedly installed on the side wall of the protective box 1 and a support rod 8 for fixing the heat dissipation moto...

Embodiment 2

[0036] This embodiment is further improved on the basis of the embodiment. The improvement is that: a blind slot 42 is opened on the side wall of the protective box 1 located on the side of the ventilation hole 3, and a filter assembly is arranged in the blind slot 42. The filter assembly includes a snap-in seat 43 slidably installed in the blind slot 42 and a filter screen 44 cooperating with the snap-in seat 43, the snap-in seat 43 is connected to the bottom wall of the blind slot 42 for pop-up filtering The elastic support member 45 of the net 44, the open end of the blind groove 42 can be detachably installed with a limit pressure block 46; by setting the filter screen 44, under the action of the elastic support member 45, dust-proof filtration can be realized while filtering Easy removal of the net 44.

[0037] The elastic supporting member 45 is not limited. In this embodiment, preferably, the elastic supporting member 45 is a compression spring.

Abstract

The invention discloses a power distribution cabinet protection device with a heat dissipation function, which comprises a protection box body and a box body door, and is characterized in that the side wall of the protection box body is provided with a dynamic heat dissipation assembly, and the dynamic heat dissipation assembly comprises a heat dissipation fan, a heat dissipation motor, a swing assembly and a lifting assembly; the swing assembly comprises an L-shaped fixing base and a supporting rod, a positioning pin and a swing motor are fixedly installed on the outer side face of the L-shaped fixing base, a disc is fixedly installed at the output end of the swing motor, and an eccentric shaft pin is fixedly installed on the disc; the lifting assembly comprises a lifting motor and a limiting block; by arranging the swing motor and the lifting motor, the swing motor rotates to drive the cooling fan to swing in the protection box body, and multi-position swing type cooling of the powerdistribution cabinet is achieved; and meanwhile, the lifting motor rotates to drive the cooling fan to move up and down, the cooling position of the cooling fan is further adjusted, and the cooling range of the cooling fan to the power distribution cabinet is better enlarged.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a protective device for a power distribution cabinet with a heat dissipation function. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and 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. The power distribution cabinet has the characteristics of sm...
