Power measurement cabinet ventilation device

Abstract

The invention discloses a power measurement cabinet ventilation device, comprising a measurement cabinet body and a through hole which is set on an inner wall at one side of the bottom of the measurement cabinet body. A mounting plate is set below the through hole. A motor is fixedly connected with a top of the mounting plate. A rotation shaft is fixedly connected with an output shaft of the motor. An inclined plate welded on the inner wall of the measurement cabinet body is set above the through hole. A top end of the rotation shaft penetrates the inclined plate and stretches to the upper side of the inclined plate. A first bevel gear is welded on the top end of the rotation shaft. A plurality of fan blades are fixedly connected with an outer side of the rotation shaft. The plurality of fan blades are located in the through hole. A strip-shaped slot is set on the inner wall at one side of the measurement cabinet body. The power measurement cabinet ventilation device is rational in design, external air can be blown into the measurement cabinet body, airflow can be uniformly blown into the measurement cabinet body, blowing blind angles are reduced, heat dissipation of the measurement cabinet body is facilitated, the measurement cabinet body is prevented from being damaged due to overheat, and use is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a ventilation device for a power metering cabinet.

Refrigeration devices are installed on ...

AI Technical Summary

Problems solved by technology

[0003] When the power metering cabinet is in continuous use, it will generate a lot of dust, and if it is not dissipated in time, it will lead to accelerated aging of the circuit

The ventilation effect of the existing ventilation device of the power metering cabinet is poor, and the heat dissipation is prone to dead angles, which makes the heat dissipation efficiency low and is not conducive to use. Therefore, we propose a ventilation device for the power metering cabinet to solve the above problems
