On-line monitoring system for insulators based on telemetry

介绍基于遥测技术的绝缘子在线监测系统设计与实现,该系统采用网络测量技术,通过数据采集单元在线实时监测输电线路上绝缘子串的泄漏电流等数据,采用无线与有线相结合的方式将数据上传到数据分析总站,通过专家知识和自学习算法,对各污区绝缘子的积污状况做出正确的评估和预测,实现故障预警,并为准确划分污区和实现状态检修提供科学依据。

In this paper,the design and realization of an on-line monitoring system for insulators is introduced.This system adopts the technology of network measurement.Data-measure-units monitor the leakage current of insulator,which is transmitted to data pro-cessing station using the way of combination of wire and wireless.The correct prediction and evaluations for the pollution insulator and its aging status,and failure early warning are given by self-learning algorithm and knowledge-based expert system.
