摘要
针对光截面感烟火灾探测器和红外对射式感烟火灾探测系统的性能开展火灾试验研究,观察两种探测器应用于段场内大空间的响应情况,分析火源种类、位置对探测有效性和可靠性的影响。结果表明,光截面感烟探测器较红外对射式感烟探测器反应灵敏,且不容易受火源位置的影响。结果可为交通车辆段大空间的火灾报警探测器选型布置提供参考。
Fire tests were made in order to study the performance of the light beam smoke fire detector and infrared radiation smoke fire detector, the response performance of the two types of detectors applied in vehicle segment was analyzed, and the influence of fire type and fire location on the effectiveness and reliability of detection was discussed. The results showed that compared to the infrared radiation smoke fire detector, the light beam smoke fire detector is more sensitive and is not easy to be affected by fire location. The results can give references for the selection and arrangement of fire detector in large space.
