| 摘 要： | 火电厂、变电站电力电缆长期运行在高电压、大电流环境下,接头容易超温过热,引起爆炸,导致火灾,建立电力电缆火灾在线监测系统具有一定的必要性,因此,设计了发电厂电力电缆温度在线监测系统,该系统现场子站设计采用新型数字式温度传感器,各电缆温度数据最后送至上位PC机进行实时显示、报警,实现了对电缆接头温度的监测与预警,有效防止了火灾的发生。

| Abstract: | Power cable in the power plant and substation works in a high voltage and large current working conditions for a long time, so superheated power cable connection would explode and catch fire. It is necessary to build up an on-line power cable temperature su- pervising system. Online temeperature monitoring system for power cable is thus developed. A new digital temperature sensor is used in the field stations, the temperature data of electric cable interface is sent to PC for real-time display and alarm, thus monitoring and alarming the temperature of electric cable, avoiding fire hazard. |
