电力电缆温度在线监测系统研究

Research on On-Line Monitoring System of Power CableTemperature

针对传统电缆温度监测方法实时性差等难题,开发了基于无线通信技术的在线监测系统,主要由非接触式温度传感器模块、通信电路模块、GPRS通信模块构成。为了验证监测系统的可靠性和稳定性,使用该系统对配电网中一正在运行的电缆进行了时间为一周的温度监测,结果表明该系统测量的温度结果准确可靠,可以长期稳定地运行。

Aiming at the problem of poor real-time performance of traditional cable temperature monitoring methods,an online monitoring system based on wireless communication technology wasdeveloped.The systemwas mainly composed of non-contact temperature sensor module,communication circuit module and GPRS communication module.In order to verify the reliability and stability of the monitoring system,the temperature of a running cable in the distribution network wasmonitored for one week.The results showed that the temperature measured by the system wasaccurate and reliable,and the system couldrun stably for a long time.
