摘要
针对大坝发电有限责任公司#1～#4机组电缆沟火灾报警系统存在的问题,通过对当前各种以测温电缆与感温电缆为主要检测元件的火灾报警系统工作原理及性能进行分析比较,提出以美国进口的线形温度探测器--FTLD测温电缆作为系统主要检测元件组成的火灾预警系统,可连续实时监测电缆沟内各区域的最高温度,克服传统的"点式"温度传感器只能探测"某点"温度以及感温电缆只能输出开关量信号,在火灾已发生,达到定温点后才能发出报警信号的不足。使用该系统对大坝#1～#4机组电缆沟火灾报警系统及防火门自动关闭系统进行完善后,系统维护量大大减少,可靠性大大提高。
Aiming at the existing problems of cable trench fire alarm system in Unitl to Unit 4 of Daba Electric Power Generation Co.,Ltd., through comparing and analyzing work principle and function of fire alarm system of all kinds of thermometric cable and induction cable as the main detecting element, puts forward linear temperature detector as FTLD linear thermometric cable imported from America as system main detecting element composing fire alarm system, can continuously real time monitor the highest temperature of every area in cable trench, after the perfection of cable trench fire alarm system in Unitl to Unit 4 and fire proofing door automatic close system, reduces system maintenance and increases reliability.
