摘要
介绍了一种基于CAN总线的绝缘子泄漏电流在线监测系统的设计与实现,该系统主要由以DSPTMS320LF2407A为核心的在线监测单元和计算机系统组成。在线监测单元实时采集绝缘子串泄漏电流及环境温湿度等信息,对数据进行预处理,并通过无线和有线相结合的方式,将信息发送给主机,以实现数据保存、信息显示、污秽状况预测及故障预警等功能,从而构成具有分布式意义的在线监测系统。
In this paper, the design and realization of an on-line monitoring system for leakage current through the insulators near substation are presented. The system with the distributed structure mainly consists of computer, and on-site monitoring units that are based on DSP. The monitoring units involve real-time sampling the leakage current through the insulators together with environment temperature and humidity, preprocessing the data and sending the useful information to the computer by CAN bus. At the same time, the computer achieves the functions of saving data, displaying the information according to users, and predicting the degree of the insulators dirtiness. Through practical tests, the system is proved to be efficient and robust.
