Local submerged gas fire-extinguishing device in electronic distribution transforming cabinet

Abstract

The present invention discloses a local submerged gas fire extinguishing device in an electronic distribution transforming cabinet. The device comprises a direct type fire detecting and fire extinguishing apparatus or an indirect type fire detecting and fire extinguishing apparatus, wherein the direct type fire detecting and fire extinguishing apparatus is divided into a carbon dioxide direct type fire detecting and fire extinguishing apparatus and a heptafluoropropane direct type fire detecting and fire extinguishing apparatus, the indirect type fire detecting and fire extinguishing apparatus is divided into a carbon dioxide indirect type fire detecting and fire extinguishing apparatus and a heptafluoropropane indirect type fire detecting and fire extinguishing apparatus. According to the device, a fire extinguishing agent container bottle filled with a fire extinguishing agent, a container valve and a fire detecting tube capable of fire extinguishing agent releasing or a releasing tube are combined into the fire extinguishing device; the fire detecting tube prepared from a non-metal soft substance material has characteristics of effective temperature susceptibility, softness and long time leakage resistance, and the like; during the using process, the fire detecting tube is placed on the position close to or above a part of the electronic distribution transforming cabinet positioned on a place, wherein the fire source is generated most possibly on the place; once the fire is generated, the position of the fire detecting tube is softened and broken, wherein the position of the fire detecting tube is subjected to the highest temperature; the gas for fire extinguishing is released in a protection area in the electronic distribution transforming cabinet in the submerged manner, the fire resource can be rapidly, exactly and effectively detected and extinguished only depending on one fire detecting tube introduced with the pressure and the fire extinguishing agent container bottle so as to combine the alarm and the fire extinguishing into the integration.

Description

[0001] technical field [0002] The invention belongs to the technical field of electric equipment maintenance, and in particular relates to a partially submerged gas fire extinguishing device in an electronic distribution cabinet. Background technique [0003] As an important part of the entire power transmission and transformation system, the substation in the power system assumes the role of connecting the preceding and the following, and the safe operation of its substation is very important. Its fire protection directly affects the safe operation of the substation. In view of whether the emergency fire protection system can be put into normal operation, it is very important to suppress and extinguish the budding fire hazards. At the same time, in view of the development of unattended substations, higher requirements are put forward for the safety of substations. At present, all substations are equipped with various forms of fire extinguishing systems, but most of them...

AI Technical Summary

Problems solved by technology

At present, all substations are equipped with various forms of fire extinguishing systems, but most of them belong to the total flooding system or local application system. Whether it is controlled by automatic, manual or mechanical operation, the fire extinguishing agent is sprayed and spread throughout the entire area. In the protective area of ​​a large space, the fire extinguishing agent is not directly sprayed into these electronic and electrical equipment cabinets where the fire occurs, and it is difficult for the gas fire extinguishing agent to penetrate into the equipment with a closed shell that is prone to fire, and the fire extinguishing is not targeted. Strong can not achieve the purpose of timely and effective fire extinguishing
