Inhibition Effect of C6F12O and CO2/N2 on Transformer Oil De-Composition Gas Flame and HF
Transformer oil de-composition into combustible gas combustion has a high risk.The new environmental protection fire extinguishing agent C6F12O has poor reignition resistance and will produce harmful product HF.Therefore,this paper studies the ef-fects of N2 or CO2 addition on the fire extinguishing performance of C6F12O extinguishing the flame with transformer oil discharges gas and the harmful product HF.Chemical dynamics method is used to calculate the effects of C6F12O mixture on adiabatic combus-tion temperature and active free radical concentration of transformer oil de-composition gas flame under different equivalent ratios and mixing ratios.The variation law of HF concentration and generation path are analyzed.Theoretical calculation results show that N2 or CO2 and C6F12O have good physicochemical collaborative fire extinguishing effect and can inhibit the formation of harmful product HF.The research results of this paper provide theoretical basis and data reference for the application of C6F12O fire extinguishing agent in electrical fire.
