Embodiment 1

[0038] A transformer oil fire extinguishing agent, comprising the following components: 5kg polyethylene glycol laurate, 2kgN-alkylglucamide, 2kgFC-4430, 1.0kg catechol, 300g hydroxypropyl cellulose, 50g mercaptobenzene Thiazole, 50g polyethyleneimine and 15kg water. Its preparation method is to first mix 5kg of polyethylene glycol laurate, 2kg of N-alkylglucamide and 10kg of water in a 10L glass stirred reactor for 1 hour to obtain mixture A, and then mix mixture A with 2kg of FC-4430 , catechol 1.5kg, hydroxypropyl cellulose 300g, mercaptobenzothiazole 50g, polyethyleneimine 50g and water 5kg were mixed and stirred for 1 hour to obtain sample 1.

Abstract

The invention discloses a transformer oil fire extinguishing agent. The transformer oil fire extinguishing agent comprises, by weight, 20-30 parts of an oil-in-water type emulsifying agent, 5-20 partsof a turbidity point improving agent, 3-15 parts of a surface spreading agent, 1-5 parts of a negative combustion catalyst, 1-5 parts of a near-fire gelatinizing synergist, 0.1-3 parts of a corrosioninhibition auxiliary and 40-60 parts of water. The invention further provides a fire extinguishing system for a transformer, and the fire extinguishing system adopts the transformer oil fire extinguishing agent. The substances in the transformer oil fire extinguishing agent are low in electric conductivity and high in insulating property and achieve the synergistic effect, and therefore the finally-obtained composite fire extinguishing agent has the advantages that the insulating property is high, the fire extinguishing efficiency is high, and electrifying is safe and reliable. In addition, water mist sprayed by the fire extinguishing system for the transformer is high in insulating property, electrified fire extinguishing can be achieved, and the outdoor wind resistance is achieved.

Description

technical field [0001] The invention belongs to the technical field of substation supporting equipment, and in particular relates to a fire extinguishing agent and a fire extinguishing system. Background technique [0002] Transformers are the power hub of the power energy Internet. Power transformers contain a large amount of flammable insulating oil. Once a fire occurs, it will cause large-scale and long-term power outages, causing heavy property losses and even casualties. According to statistics, every 63 to 81 transformers will have a fire in their 40-year service life. Nowadays, the overall base of power transformers is very large, and transformer fires have become a major disaster that threatens the safe supply of power. For example, on June 18, 2016, a substation transformer in a certain province caught fire, and multiple transformers were burned down. The fault lost 243,000 kilowatts of load, and 86,500 power outage users caused a huge social impact. Now there is...
