城区电力电缆接头故障在线监测系统

现有的电力电缆接头温度在线监测系统大多由于现场监测装置供电困难、数据传输距离受限、需要进行大量的现场施工等原因，仅适合于发电厂、变电站内的使用。针对城区电力电缆接头点多量大、分布范围广等特点，研制了一套新的监测系统；监测系统现场装置以C8051F020单片机和Wavecom Q2406A模块为核心，对电缆接头温度数据采集和监测，利用全球移动通信系统(GSM)短消息服务来实现数据传输，完成远方监测与管理。经过实际运行检验，系统运行稳定可靠，收到了良好的效果。

On-line monitoring systems for power cable junctions in city zone

The current on-line monitoring systems for power cable junctions have some disadvantages,such as difficulty of the power supply of detecting devices,the restricted distance of data transmission and the high cost of devices.Because of the disadvantages,they are just suitable for the transformer substation or the power plant.In this paper,a novel monitoring system which combines with the practical running situation of the power cable in the city is achieved.The monitor system uses the low consumption microcon...
