A fire extinguishing type distribution cabinet based on the principle of high temperature degaussing

Abstract

The invention discloses a fire extinguishing type power distribution cabinet based on the principle of high temperature degaussing, which comprises a cabinet body, a plurality of cooling holes are symmetrically opened on the side wall of the cabinet body, sliding cavities are symmetrically opened on the side wall of the cabinet body, and the sliding cavity is symmetrically opened on the side wall of the cabinet body. The inner wall of the cavity is sealed and slidably connected with a slide plate, and the side wall of the slide plate is provided with a plurality of through holes matching with the cooling holes. The top of the slide cavity is fixedly connected with a permanent magnet block, and the top of the slide plate is fixedly connected with a magnet. The lower end of the magnetic block is fixedly connected with the upper end of the magnet through a spring. In the present invention, the temperature in the cabinet reaches the Curie point of the permanent magnet block, so that the permanent magnet block is demagnetized due to high temperature, and then the magnet drives the slide plate to slide down under the action of the spring, so that the through hole and the heat dissipation hole are misaligned, so that the outside air cannot pass through to dissipate heat. The hole enters the cabinet, and the cabinet is subjected to oxygen isolation treatment, and the hydrochloric acid solution and calcium carbonate particles generate carbon dioxide, which increases the concentration of carbon dioxide in the cabinet and accelerates the extinguishing of the fire in the cabinet.

Description

Technical field[0001]The present invention relates to the technical field of power equipment, and more particularly to a fire extinguishing power distribution cabinet based on high temperature degaussing principles.Background technique[0002]The power distribution cabinet is the collective of the motor control center that assigns the electric energy of a circuit of the previous level distribution equipment to the near-level load and provides protection, monitoring and controlling these loads. In people's lives, the power distribution cabinet is not Or one of the electrical equipment that is missing.[0003]Since a large amount of electronic components in the distribution cabinet are used to ensure the normal operation of the power distribution cabinet, it will produce higher heat in the power distribution cabinet, especially in the summer, the temperature in the power distribution cabinet will rise sharply, making The contents of the distribution cabinet are prone to fire, resulting in...

AI Technical Summary

Problems solved by technology

[0003] Since a large number of electronic components are installed in the power distribution cabinet to ensure the normal operation of the power distribution cabinet, high heat will be generated in the power distribution cabinet, especially in summer, the temperature in the power distribution cabinet will rise sharply, making Fires are prone to occur in the power distribution cabinet, causing property losses. In addition, most of the current fire extinguishing of the power distribution cabinet is to open the door of the power distribution cabinet to extinguish the fire. However, the moment the door of the power distribution cabinet is opened, the fire in the power distribution cabinet It will flow outwards, which may easily lead to safety accidents
