摘要
电力电缆中间接头的温度是反映其运行状态的重要参数,为了更加全面、准确的监测电缆接头的表面温度,文中提出了一种基于"面"测温的电缆接头温度监测新方式,即每个无线温度传感器带有6个测温探头,监测过程中只读取其中的温度最高值。系统实测结果表明这种新的电缆接头温度监测方式具有低功耗、监测时间长和传输距离远等优点,已成功用于现场监测,性能稳定。
The temperature of power cable joint is an important parameter to reflect its operating condition. A novel method to measure the surface temperature of power cable joint in a accurate and comprehensive way was proposed based on the wireless temperature sensor which have six temperature detectors forming a measuring surface, where only the maximum value of six measurement results was send to data acquisition unit. The experimental results show that the monitoring system has the advantages of low power consumption,long period operation and long distance transmission,which has been successfully used in the field monitoring with stable performance.
