AI Technical Summary

Technical Problem

The pressure relief device of the existing pull-out low-voltage switch cabinet depends on the melting of nylon screws, and the reaction temperature is high, making it difficult to lower the temperature and pressure in the cabinet in time, and it requires staff to reinstall it after the pressure relief, which is more troublesome.

Method used

A pressure relief device including a temperature sensor, a lift control assembly and a cover plate is designed. When the temperature sensor monitors that the temperature in the cabinet exceeds the first threshold, the lift control assembly automatically opens the cover plate to relieve pressure until the temperature is lower than the second threshold, and then closes it to realize automatic repeated pressure relief.

Benefits of technology

It achieves the effect of timely lowering the temperature and pressure in the cabinet, avoiding the trouble of manually reinstalling after pressure relief, and the pressure relief method can be automatically repeated, which is more convenient.

Abstract

The invention relates to the technical field of air conditioning, in particular to a draw-out type low-voltage switch cabinet which comprises a cabinet body, a plurality of drawers are arranged in the cabinet body, each drawer is provided with an electric power function unit, a pressure relief device is arranged in the cabinet body, and the pressure relief device comprises a temperature sensor, a lifting control assembly and a cover plate. The temperature sensor is arranged in the cabinet body, the temperature sensor is used for monitoring the temperature in the cabinet body, the cover plate is arranged at the top of the cabinet body, the cover plate is connected with a lifting control assembly arranged in the cabinet body, and a controller is connected between the lifting control assembly and the temperature sensor. And the lifting control assembly opens the cover plate until the temperature in the cabinet body is lower than a second threshold value, and then the lifting control assembly drops the cover plate, so that the temperature and the pressure in the draw-out type low-voltage switch cabinet can be reduced in time, and the situation that a worker needs to re-install the draw-out type low-voltage switch cabinet after pressure relief is avoided.
