变电站易维护式点型火灾探测器装置的设计研究

Design and Research of Easy-to-maintain Point-type FireDetector Device in Substation

变电站多个设备室配备有点型火灾探测器,火灾探测器作为火灾自动报警系统的重要组成部分,日常运行易出现元器件故障功能失效、传感元件积污误发告警等问题,为了避免在变电站主设备出现故障火灾时火灾自动报警系统因故障无法发挥作用,需要对异常、故障的点型火灾探测器进行维护保养或者维修更换,维修处理需要对设备进行停电操作。文章重点对点型火灾探测器运行维护问题进行分析,提出可方便将点型火灾探测器移出带电设备区域或者紧凑空间区域的设计方案。

Multiple equipment rooms in substations are equipped with point-type fire detectors.As an important part of the automatic fi re alarm system,fi re detectors are prone to problems such as component failure and function failure,and sensor components accumulating and false alarms during daily operation.When the main equipment of the substation fails and fires,the automatic fire alarm system fails to play a role.It is necessary to maintain or repair the abnormal and faulty point-type fi re detectors.The repair process requires a series of problems such as power failure operations on the equipment.The text focuses on the analysis and improvement of the operation and maintenance of point-type fi re detectors,and proposes a design scheme that can easily move the point-type fi re detectors out of the charged equipment area or the compact space area.
