高压绝缘子远程在线检测诊断系统的初步研究

Preliminary Study of On-line Monitoring and Diagnostic System for Insulators on HV Lines

提出了高压线路绝缘子远程分布式在线监测与集中式故障诊断系统的初步实现方案。在现场单元中,通过多个传感器获取绝缘子串的泄漏电流、脉冲电流和环境参数等数据,并利用数字信号处理器(DSP)预处理数据,再借助多种无线通信网络传输数据。安装于电业部门的后台单元接收和管理现场数据并借助多种人工智能技术诊断整条线路绝缘子的运行状况。

The preliminary solution is proposed for the remote distributed on-line monitoring and centralized fault diagnostic system of insulators on HV lines. In its on-site u-nit, the leakage current and pulse current through an insulator string and the environmental conditions are obtained from different sensors. These data are preprocessed in a DSP chip and then transmitted via wireless communication networks. The background unit is installed in power utilities, which receive and manage the on - site data. Based on several kinds of artificial intelligence technologies, the operating condition of insulators on a whole HV line can be diagnosed.
