针对井下高压隔爆开关所处大电流、强电磁与潮湿环境,开发了基于数字型红外温度传感器的单片机在线监测系统。该系统与高压开关融为一体,可获得实时温度数据和声音报警,具有抗电磁干扰强、测温准确、使用寿命长、可靠性高等优点。经实际应用与检验,效果良好。
In view of the high current, strong electromagnetic and damp environment in the underground high-pressure flameproof switch, an on-line monitoring system based on digital infrared temperature sensor was developed. The system integrates with high-voltage switch to obtain real-time temperature data and audible alarm. It has strong anti-electromagnetic interference, accurate temperature measurement, long service life and high reliability. The practical application and testing, the effect is good.
