基于无线通信的地下电缆接头故障巡检系统

摘要

The temperature is an important parameter reflected by operating condition of power network.Aimed at the puzzle of being difficulty to inspect the fault of underground cable joint,the paper explored a sort of patrol inspection system of underground cable joint fault based on wire-less communication.In the paper,it analyzed the mechanism of hidden fault produced by the joint,designed the system of front end detection and background analysis and its corresponding function modules,and realized the patrol inspection for cable joint fault by means of wireless communication.The test data demonstrated that the system could realize the patrol inspection coverage over a wide area,and be used on line by networked computer.The experiment result shows that the system design is feasible and available effectively.%电缆接头温度是反映电网运行状态的重要参数。针对地下电缆接头故障难以检测的问题，探讨了一种基于无线通信的地下电缆接头故障巡检系统。分析了产生接头故障隐患的机理，设计了前端检测与后台分析系统及其相应的功能模块，利用无线通信方式实现了对地下电缆接头故障的巡检。测试数据显示：该系统可在大范围内实现巡检覆盖，便于计算机联网使用。实验结果表明：系统设计是可行和有效的。
