Abstract

Abstract: In order to explore the effectiveness of compressed air foam aerial fire fighting robot in dealing with oil immersed transformer fires, this paper developed a 1：1 full-scale oil immersed transformer fire model, simulated the oil pool fire at the top of the main oil tank, 7 combustion holes, oil spill fire and bottom oil pool fire, and conducted a full-scale oil immersed transformer fire suppression test using a compressed air foam aerial fire fighting robot. The result shows that a compressed air foam aerial fire fighting robot with a flow rate of 1 200 L/min can extinguish the fire of full-scale oil immersed transformer, control the fire in 163 s, and completely extinguish the fire in 474 s without re burning.

Key words: oil immersed transformer, fire model, compressed air foam, aerial fire fighting robot, extinguishing technology
