城市配电网电缆接头温升在线监测系统研究

Research of on-line monitoring system for power cable joint temperature rise in urban power distribution network

结合城市配电网地埋电力电缆接头点多、量大、分布较广等特点,设计了一种基于CAN-BUS总线分布测量和GSM/GPRS无线通讯的城市配电网电缆接头温升在线监测系统,并对该系统的综合设计方案、逻辑架构组成、现场分散采集系统,以及上位机管理站网络化动态检测平台的功能作用进行了详细分析。结果表明:该系统解决了地埋电力电缆运行中接头温升故障率较高且监测不方便等问题,提高了设备可靠运行水平。

Combining with the characteristic of buried cable in urban power distribution network such as multiple joint, large amount and wide distribution, based on CAN-BUS distribution measurement and GSM/GPRS wireless communication designs an on-line monitoring system for temperature rise of power cable joint in urban power distribution network. Analyzes the integrated design schemes, logic construction frame composition, distributed collection system and the function of network dynamic monitoring platform of upper monitor management station. The result shows that the system can solve the problems of higher failure rate and inconvenient monitoring of joint temperature rise in the operation of buried power cable,and improve reliable operation level of equipments.
