无源无线电缆测温技术在配电网自动化中的应用

Application of Passive Wireless Cable Temperature Measurement Technology in Distribution Network Automation

电缆头运行温度是反映电缆运行状态的重要参数。采用无源测温技术对电缆三相接头温度进行检测,提取无线温度接收终端数据实现电缆头温度监测并实时上传至配电自动化系统,解决采用人工手持式红外测温设备定时巡检电缆头温度不全面不连续。人员不易到达盲区的问题,避免遇到突发事件造成不必要的人员伤亡,并有效排除电缆安全隐患。

The running temperature of the cable head is an important parameter reflecting the running state of the cable.Passive temperature measurement technology is used to detect the temperature of the three-phase joint of the cable,and the data of the wireless temperature receiving terminal is extracted to realize the temperature monitoring of the new cable head and uploaded to the distribution automation system in real time,and the timing inspection cable using the manual handheld infrared temperature measuring device is solved.Head temperature and blind areas that are difficult for people to reach,avoiding unnecessary casualties caused by unexpected events,effectively eliminating cable safety hazards.
