Description

Technical Field

[0002] During the operation of oil-immersed transformers, short-circuit faults may occur at the bushing. The short-circuit current formed will release a lot of heat, causing heat damage to the transformer insulation material, and then triggering high-energy arcs to penetrate the bushing, releasing and igniting the transformer oil to form a fire accident, resulting in various fire forms such as flowing fire, three-dimensional fire, and engulfing fire. If not controlled in time, it is very easy to evolve into a catastrophic disaster, resulting in adverse social impacts and huge economic losses. Therefore, it is urgent to study the simulation of different fire scenarios for oil-immersed transformer fires.
