电力电缆中间接头的温度是反映其运行状态的重要参数。通过对接头温度进行测量和监视,可以全面了解其绝缘老化情况、准确评估其工作状态、及时发现其故障隐患,对提高电缆接头运行可靠性、减少故障发生次数、降低故障损失具有重要意义。应用检测技术、计算机技术和通信技术等手段,设计出了集测量、显示、打印、报警和远传通信等多项功能于一体的集散式电力电缆接头温度监测系统。该系统投入实际运行后,取得了很好的应用效果。 The temperature of the middle of the power cable is an important parameter that reflects its operating status. By measuring and monitoring the temperature of the joint, it is possible to fully understand its insulation aging status, accurately evaluate its working status, and find out its hidden troubles in time, which is of great significance to improve the reliability of the cable joint, reduce the number of faults and reduce the fault loss. By means of detection technology, computer technology and communication technology, a temperature monitoring system for distributed power cable joint is designed, which integrates many functions of measurement, display, printing, alarm and remote communication. The system put into practical operation, made a very good application effect.
