基于无线传输的交联聚乙烯电缆故障在线监测系统研究

摘要

以XLPE交联聚乙烯电缆为研究对象,对局部放电故障检测方法进行研究,设计了基于超高频法的电缆故障在线监测装置,通过对调理滤波电路、信号无线传输电路等模块的设计,搭建了基于STC89C52的监测系统,实现对电缆故障的实时监测.%In this paper,using the XLPE cross-linked polyethylene cable as the research object,we study the detection method for local discharge faults and design an on-line monitoring device for power cable faults based on UHF.The monitoring system based on STC89C52 is established through design of models for the conditioning filter circuit,signal wireless transmission circuit and etc to realize the real-time monitoring of cable faults.
