Rapid fire extinguishing agent for vegetation fire of power transmission lines

Abstract

The invention relates to a rapid fire extinguishing agent for vegetation fire of power transmission lines. The fire extinguishing agent is formed by mixing the following components in parts by weight: 5-15 parts of sodium chloride, 8-20 parts of ammonium carbonate, 4-12 parts of urea, 4-15 parts of dipotassium phosphate, 0.5-5 parts of ethylene glycol, 1-6 parts of sodium tripolyphosphate and 50-70 parts of water. When in use, the fire extinguishing agent product is diluted with water in the ratio of 1:20; the obtained solution is filled in a water mist fire extinguisher; water mist spray is sprayed to the fire scene to put out the fire. Compared with existing technical products, the fire extinguishing agent has the advantages of higher vegetation fire extinguishing capacity, high fire extinguishing speed and high efficiency and is capable of reducing the load of fire extinguishing staff and increasing the fire extinguishing mobility; the fire extinguishing agent is very suitable for the rapid fire extinguishing of the vegetation fire of the power transmission lines and guarantee is provided for the safe and stable operation of the power transmission lines.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a rapid fire extinguishing agent for mountain fires in power transmission lines. Background technique [0002] In recent years, frequent wildfires near transmission lines have seriously threatened the safe and stable operation of transmission lines, especially UHV transmission lines. During the Qingming period in 2012, mountain fires occurred frequently on transmission lines in Hubei, Zhejiang, Anhui and other regions, causing a number of 500kV AC lines to be out of service due to faults, and ±500kV Jiangcheng DC caused pole I to be locked due to mountain fires; in early March 2013, many Large-scale wildfires broke out again in several provinces, resulting in blockage or abnormality of many DC lines such as Jinsu, Fufeng, and Longzheng. The timely rescue of the initial wildfire on the transmission line is the most effective means to avoid the expansio...

Problems solved by technology

These fire extinguishing agents are all based on the principle of covering the air to extinguish fires, and are only suitable for indoor conventional fire extinguishing. For mountain fires in open areas in the wild, due to the uneven burning surface, the spraying coverage is very poor, often resulting in a serious shortage of fire extinguishing power, and even cannot meet the requirements at all.
