试论风力发电机组灭火介质的合理选择

Selection of fire extinguishing medium for wind turbines

分析风电机组的火灾原因,总结风电机组主要的火灾类型。针对目前用于风电机组自动消防系统的几种灭火介质,包括超细干粉、热气溶胶、Novec 1230、二氧化碳、七氟丙烷和水系灭火剂等,比较其基本性能,包括对环境的要求、储存方式、灭火速度、灭火剂毒害性等。结合某风电场的实际情况进行分析,提出风力发电机组机舱内适宜使用超细干粉灭火装置,控制柜内适宜使用热气溶胶灭火装置。

The fire cause of wind turbines was analyzed and the main fire types were concluded. For several fire extinguishing media applied in automatic fire control system of wind turbine as superfine powder,sol, Novec 1230, carbon dioxide and water-related fire extinguishing agent, the basic characteristics were compared including requirements for environment, storage methods, fire extinguishing speed and toxicity. Combined with the actual situation of a wind farm, it was proposed that superfine dry powder is recommended for fire extinguishing in the cabin while hot aerosolis recommended for fire extinguishing in control cabinets.
