Electric meter box fire extinguishing device based on thermal induction

Abstract

The invention discloses an electric meter box fire extinguishing device based on thermal induction, and belongs to the field of electric meter boxes. According to the electric meter box fire extinguishing device based on thermal induction, and based on the scheme, an aqueous solution is heated through heat, and water vapor generated by heating the aqueous solution rises to be in contact with a soluble sealing layer and is melted, so that effervescent disintegrant falls into the aqueous solution to be subjected to a contact reaction, carbon dioxide gas is released, and the open fire combustion condition is reduced; a shape memory spring deforms when heated, so that a sealing cover seals an inner space of a reaction inner cylinder; a LDPE film in a release hole is extruded to be broken by pressure on the outer side of the reaction inner cylinder, so that insulating powder on the outer side of the reaction inner cylinder and the carbon dioxide gas are released at the same time, and the open fire combustion condition in an electric meter box is further reduced; and pressure generated when compressed air encounters heat pushes a sliding extrusion block in a connecting pipe, insulating glue is extruded into an isolation ring through the pressure, electric leakage and leakage in the electric meter box can be isolated, and maintenance casualties are reduced.

Description

technical field [0001] The invention relates to the field of electric meter boxes, more specifically, to a fire extinguishing device for electric meter boxes based on thermal induction. Background technique [0002] The material used to manufacture the low-voltage cable branch box is a resin-based composite material. The main components of the box are ABS engineering plastics, polycarbonate transparent PC materials, DMC, and SMC. Four kinds of materials are injected and pressed. [0003] This composite material is composed of two parts: matrix - polyester resin; reinforcement material (referred to as PC, SMC), so it is also called transparent PC material, fiber-reinforced polyester material, transparent PC material, fiber-reinforced unsaturated Polyester is a composite material based on unsaturated polyester resin. These two materials are insoluble, flame retardant and recyclable. The latter material has the disadvantages of infusibility and non-recyclability. Its physical s...

Problems solved by technology

[0005] When the circuit is aging or the line falls off, it is easy to cause an open fire inside the meter box, which cannot be extinguished in time, not only causing damage to the meter circuit in the meter box, but also easily causing injury to personnel
