Study on Full-Size Fire Extinguishing Experimental Conditions of Main Transformer in UHV Substation
Xilong Chen, Xian Gao · 2023
In the operation process of UHV substation, the fire accident risk of UHV AC transformer is large. If the fire accident occurs in UHV transformer, it will seriously affect the safe operation of power grid. Full-scale fire extinguishing experiment is an important method to verify the effectiveness of fire extinguishing system and determine the parameters of fire extinguishing system. The scientificity of the experimental scheme will directly determine whether reliable and effective experimental data and results can be obtained. In this paper, the full-scale fire extinguishing experimental conditions of the main transformer in UHV substation will be studied to ensure that the fire characteristics, boundary conditions, adverse working conditions and key fire parameters of the experimental simulation are close to the real fire scene.
