Embodiment 1

[0069] A transformer high temperature oil fire oil insulation fire extinguishing agent, comprising the following components: 5kg YM-316, 40kg XP80, 15kg65HD50, 40kg water. The preparation method is first to mix YM-316 (Shanghai Yumu Chemical Co., Ltd.) 5kg, XP80 (Germany BASF) 40kg, 65HD50 (Nanjing Lihongde Trading Co., Ltd.) 15kg and water 40kg, and stir them evenly in a 200L glass stirring reactor. The mixture was obtained for 1 hour, i.e. Sample 1 was obtained.

Embodiment 5

[0077] A transformer oil fire fire extinguishing agent comprises the following components: 4kg FC-430 (US 3M Company), 30kg Surfynol 440 (US Air Chemicals), 25kg Aculyn 33 (Hanlin Chemical Co., Ltd.), 41kg water. Its preparation method is to firstly stir 4kg FC-430, 30kg Surfynol 440, 25kg Aculyn 33 and 41kg water in a 200L glass stirred reactor for 1 hour to obtain a mixture, that is, to obtain sample 5.

Embodiment 6

[0079] A transformer oil fire extinguishing agent, comprising the following components: 10kg Intechem-14-2A (Shanghai Yingzheng Technology Co., Ltd.), 20kg Helmol-10 (German Hamm), 20kg Cellosize QP15000H CGR (American Dow), 50kg water . Its preparation method is to first mix Intechem-14-2A 10kg, Helmol-10 20kg, Cellosize QP15000H CGR 20kg and water 50kg in a 200L glass stirred reactor for 1 hour to obtain a mixture, namely to obtain sample 6.

Abstract

The invention discloses an electrified fire extinguishing sprayer, an electrified explosion-proof fire extinguishing device and an electrified fire extinguishing method. The electrified fire extinguishing sprayer comprises a connecting part used for being connected with a pipeline, and a nozzle used for spraying water mist. The electrified fire extinguishing sprayer is characterized in that the electrified fire extinguishing sprayer further comprises a sprayer body connected between the connecting part and the nozzle; at least two rotational flow guide vanes are arranged inside the sprayer body in an oblique crossing mode; oblique crossing gaps of the rotational flow guide vanes form rotational flow channels, and at least one direct flow channel is arranged on each rotational flow guide vane in the radial direction, so that the direct flow ejected by the direct flow channels and the rotational flow ejected by the rotational flow channels realize turbulent flow. The electrified fire extinguishing sprayer has the advantages of a direct-injection pressure spray type sprayer and the cyclone atomization sprayer, the spray distance is long, the atomization effect is good, and the electrified insulation performance is high.

Description

technical field [0001] The invention relates to the field of fire extinguishing for oil-immersed transformers, in particular to a live fire extinguishing nozzle for long-distance jet atomization, a charged explosion-proof fire extinguishing device and a live fire extinguishing method. Background technique [0002] Oil-immersed transformer fire has become a major disaster that threatens the safety of power supply. Ordinary oil-immersed power transformers contain nearly 100 tons of hydrocarbon mineral oil, and UHV converter transformers contain more than 100 tons of transformer oil. When a fault occurs, there is a risk of fire and explosion, and it may evolve into a catastrophic large-scale fire. For example, in June 2016, a fire broke out in a substation in the southern suburbs of Xi'an City, Shaanxi Province, causing multiple transformers to burn out, causing a load loss of 243,000 kilowatts and power outages to 86,500 households; A fire broke out due to a fault, causing m...
