冶金部安全环保研究院研制的电缆隧道防火预警系统,是通过微机将漏电探测器、温度探测器及感烟探测器组成探测器阵,实现监视电缆的运行工况及隧道的环境状况,及时地对可能引起电缆隧道火灾的事故进行预警,从而避免火灾的发生。单放射源离子感烟探测器及感烟-感温复合探测器,吸收了国外近年来新型产品的优点,既适于工业使用,也适于民用。 Metallurgical Safety and Environmental Protection Research Institute developed a cable tunnel fire early warning system is through the computer leak detectors, temperature detectors and smoke detectors constitute a detector array to monitor the operating conditions of the cable and the tunnel environmental conditions, in a timely manner Preventing accidents that may cause cable tunnel fires, thus avoiding the occurrence of fire. Single radioactive ion smoke detector and smoke - temperature composite detector, absorbing the advantages of new foreign products in recent years, both for industrial use, but also for civil use.
