全户内变电站主变室火灾报警装置的优化选择

Optimization Selection of Fire Alarm Device for Indoor Substation Main Transformer Room

110 kV全户内变电站主变室火灾报警装置常采用线型感温电缆、吸气式感烟及红外对射探测器,但变电站投入使用后,探测器一旦出现故障或失效,检修或更换必须要将主变停电,考虑到供电可靠性和给用户带来的不便,往往将检修时间一拖再拖,这给整个变电站的防火安全带来了极大的挑战和隐患。因此,作者根据多年的工作经验,结合实际产品性能,在苏州地区的一个变电站建设中首次采用了火焰探测器,该产品安装灵活,既能满足防火要求,又便于检修和维护。

The 110 kV transformer indoor substation room fire alarm device often use linear temperature cable, aspirating smoke and infrared detectors, but after putting substation into use, once the detector occurs the malfunction or failure,maintenance or replacement of the main transformer must be cut off. Taking into account the power supply reliability and inconvenience to the user, the maintenance time is often delayed, which gives safety of the whole substation fire great challenges and risks. Therefore, based on years of experience, author , combines with the actual product performance, firstly adopts a flame detector in the construction of a substation in the Suzhou region. The product installation is flexible, whichcan meet the fire requirements, but also easy to repair and maintenance.
