Electrical cabinet with fire extinguishing and cooling functions

Abstract

The invention discloses an electrical cabinet with fire extinguishing and cooling functions. The invention belongs to the field of firefighting, the invention discloses the electrical cabinet with fire extinguishing and cooling functions, according to the scheme, when open fire occurs outside the electrical cabinet, the open fire burns outside a glass tube; the carbon dioxide gas in the glass tubeexpands to cause the glass tube to burst; a strip-shaped limiting block enables the fixed plate to stably slide downwards through balls in a limiting groove; a storage bag is extruded by a pressing plate through the fixing plate; a needle punctures the storage bag and penetrates through a foaming agent and a separation membrane; the foaming agent, aluminum sulfate and a sodium bicarbonate solution are mixed to generate a large amount of foam and carbon dioxide, the foam and carbon dioxide are ejected out of a discharge hole, and therefore, the open fire is covered; when the fixing plate encounters the open fire and generates high temperature, a PVC film encounters the high temperature and melts, so that inorganic salt in a T-shaped barrel falls into a reaction cavity, the inorganic salt and water in the reaction cavity are mixed and react to generate a heat absorption phenomenon, and the outer wall of the electrical cabinet is cooled.

Description

technical field [0001] The invention relates to the field of fire protection, and more specifically relates to an electrical cabinet with the function of fire extinguishing and cooling. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel sheets, cold-rolled steel sheets are softer and more suitable for the production of electrical cabinets. Electrical cabinets are widely used mainly in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] The electrical cabinet is also called the power distribution cabinet. The power distribution cabinet is divided into the power distribution cabinet, the lighting d...

AI Technical Summary

Problems solved by technology

[0005] At present, a large number of electrical cabinets are used in electrical engineering. When an open fire occurs outside the electrical cabinet, the staff cannot extinguish it in time, and the open fire even spreads to multiple electrical cabinets, resulting in damage to most of the electronic components inside the electrical cabinet. reduce loss
