Fire safety properties of some transformer dielectric liquids

摘要

This paper reviews the fire hazard properties of some transformer fluids of reduced flammability. Fluids examined include a silicone (polydimethylsiloxane), a high molecular weight aliphatic hydrocarbon, and a polyalphaolefin. Fire hazard properties considered include ease of ignition, flame spread, fire growth and rate of heat release (large scale pool burns), rate of smoke evolution, fire gas and smoke toxicity, and extinguishment behavior.
