| 摘 要： | 对具有强电磁干扰的变电站的火灾隐患进行预防和监测,多年来人们一直在探讨,如单独利用传统的电子传感器或采用新型的光纤光栅温度传感系统来实施远程监控,但由于传输导线的绝缘性能不稳定、光纤光栅传感器的成本较高、施工工艺复杂,故不能在电力火灾的监控中广泛采用.通过对烟雾火灾报警与光纤光栅测温相结合的探讨,不仅能对变电站的关键热点实施实时监测,而且还能对电力系统进行宏观监控以预防电力火灾.

| Abstract: | In the electrical power system some spots have the strong electromagnetic interference and terrible envi- ronment. Traditional electronic sensors require metal wire for signal transmission. For it is unable to guarantee its transmission, the wire has reliable also stable insulating ability in the high voltage environment, thus it is unable to realize the online precision measurement. New fiber Bragg grating temperature sensor system is able to achieve real - time remote monitoring of the electricity system febrile node. However, due to the higher cost of fiber Bragg grat- ing sensors, and complex construction process, it is not suitable for substation fire monitoring. We combine the smoke/ire alarm system and fiber Bragg grating temperature system, and then achieve not only real -time monito- ring of key hot spots of the substation and the elimination of fire hazards, but also macro monitoring of substation and increase of the reliability of the system. |
