在对风力发电机组进行火灾风险分析的基础上,利用风电机组火灾模拟试验装置对点型离子感烟、吸气式感烟、感温、图像型、缆式线型感温、红外火焰探测器等6种火灾探测器进行通风条件和非通风条件的模拟火灾探测试验。试验结果表明,感烟和感温火灾探测器受风电机组通风系统影响较大;感光型火灾探测器报警速度快,灵敏度极高,不受通风影响,但容易受到舱内众多设备的遮挡;缆式线型感温火灾探测器报警速度慢,宜紧贴敷设在电缆桥架、电缆夹层、发电机等重点防火部位。
Based on the fire risk analysis of the wind turbine, the fire simulation test device of the wind turbine is used to test the point-type ion smoke, aspirating smoke, temperature sensing, image type, cable type temperature sensing, infrared flame detector Six kinds of fire detectors for ventilation and non-ventilation conditions of simulated fire detection test. The test results show that the smoke detector and the thermal fire detector are greatly affected by the ventilation system of the wind turbine. The sensitive fire detector has the advantages of high alarm speed, high sensitivity and no influence of ventilation, but is easily blocked by many devices in the cabin. Cable Type linear temperature sensor fire alarm slow, should be close to the laying of the cable bridge, cable mezzanine, generators and other key fire site.
