Abstract

Abstract: Taking a typical transformer oil-immersed paper bushing fire accident as the object, the FDS is used to study the influence of the lip height on the burning rate and flame height of the bushing oil pool fire. The results show that with the increase of lip height, both of the mass loss rate and heat release rate decay exponentially, and the combustion efficiency first decreases and then increases. A non-dimensional flame height prediction model coupling the size of the bushing and the lip height is proposed.

Key words: transformer bushing, pool fire, lip height, burning rate, flame height
