风力发电机组火灾特性与消防系统应用研究

Research on features of fire and the application of fire protection system on wind turbine

风力发电机组因摩擦、接触电阻增大、电气元件老化等易引起火灾。风力发电机组火灾荷载密度大,如发生火灾易造成较大经济损失,易引起森林或草原火灾。风力发电机组内部及外部的强气流对火灾探测器的快速响应和灭火装置的灭火效能有较大不利影响。电气设备控制柜、变频柜等的外壳密闭性较强,需针对性采取相应探测手段和灭火措施。风电场内机组布置分散且相隔较远,火灾报警和灭火控制系统要有较强的远距离信号传输能力和网络集成能力。

Friction,big contact resistance and old electrical element may cause fire on wind turbine.The wind turbine has big fire load density,so the fire on it may cause big economical loss or big fire on forest and grass.The strong airflow inside or outside the wind turbine affects the response of fire detector and efficiency of fire extinguishing apparatus badly.Some pertinence measures must be selected because the good obturation of cabinet of electrical element and frequency conversion element.The wind turbine is dispersive and distant,so the fire alarm system and must have capability of long-distance transmission and network integration.
