摘要
为了能够有效提升核电厂内电缆桥架故障火灾危险性和探测技术的准确性和可靠性,本文采用火灾实体试验的方法,通过分析高压电缆桥架火灾蔓延风险规律,对各类型火灾自动报警技术的响应时间的情况进行分析和比较,研究核电厂电力舱内常用探测器的性能研究结果表明:热解粒子探测器、接触式缆式线型感温火灾探测器可以较早的探测到电缆温度异常变化的现象,可用于早期预警,热解粒子探测器对烟粒子浓度、电缆明火燃烧变化均较为敏感,可用于核电厂电力舱室的空间探测。
The performance of commonly used fire alarm detector in power compartment of nuclear jower was studied,througl the response time by various types of automatic fire alarm detectors at full-scale fire test.The result demoustrated that the abuormal tenperature riscs on cable can be early detected by cable line-type leat detector.The concentration of smoke particles was more sensitive by point-type jpyrolysis particle detector.it can be applierd for space cletection in power compartment of nuclear power.In acddition.point-type pyrolysis particle detector possesserd more reliability whien as a space-type fire dletector.due to the open flame was more sensitive.
