Discussion on Fire Safety Problems of Oil- immersed Transformers
Yuting Zhai · Building Electricity · 2015
Fire features and fire reasons of oilimmersed transformers are analyzed, and the fire safety problems of oil-immersed transformers are studied from three main aspects, i. e. fire prevention technologies such as gas relays and pressure relief valves, fire detection technologies such as heat detectors and smoke detectors, and firefighting systems such as stationary water-spray fire extinguishing system, water-mist fire extinguishing system, oildrainage nitrogen-filling fire extinguishing system and SP synthetic foam-spray fire extinguishing.
