Fire extinguishing type power distribution cabinet based on high-temperature demagnetization principle

Abstract

The invention discloses a fire extinguishing type power distribution cabinet based on a high-temperature demagnetization principle. The cabinet comprises a cabinet body, the side wall of the cabinet body is symmetrically provided with a plurality of heat dissipation holes. Sliding cavities are symmetrically formed in the side walls of the cabinet body, sliding plates are slidably connected to theinner walls of the sliding cavities in a sealed mode, a plurality of through holes matched with the heat dissipation holes are formed in the side walls of the sliding plates, permanent magnets are fixedly connected to the tops in the sliding cavities, magnets are fixedly connected to the upper ends of the sliding plates, and the lower ends of the permanent magnets are fixedly connected with the upper ends of the magnets through springs. According to the invention, the temperature in the cabinet body reaches the curie point of the permanent magnet block; the permanent magnet blocks are demagnetized due to high temperature; the magnets drive the sliding plates to slide down under the action of the springs, so that the through holes and the heat dissipation holes are staggered, external air cannot enter the cabinet body through the heat dissipation holes, oxygen isolation treatment is performed in the cabinet body, carbon dioxide is generated through a hydrochloric acid solution and calcium carbonate particles, the concentration of the carbon dioxide in the cabinet body is increased, and extinguishing of a fire in the cabinet body is accelerated.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a fire-extinguishing type distribution cabinet based on the principle of high-temperature degaussing. Background technique [0002] The power distribution cabinet is the collective name of the motor control center. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads and provide protection, monitoring and control for these loads. In people's lives, the power distribution cabinet is indispensable. One of the indispensable electrical equipment. [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...

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
