摘要
介绍交叉互联XLPE电缆向量运算法的基本原理,针对交叉互联连接方式下难以直接测得流经电缆主绝缘电流的问题,设计基于向量运算法的交叉互联连接方式下的XLPE电缆绝缘在线监测系统。该系统由电流信号采集单元、电流信号传输单元和远程综合信息管理单元组成,采用GPRS无线方式进行数据传输。根据监测系统在Matlab/simulink平台中搭建相应的仿真模型,验证系统的有效性。
This paper introduced the basic principle of the vector calculation method for the Crossing-linked cable.According to the difficulty of directly measurement the main insulation current of the cable,an insulation online monitoring system for the cable based on the vector calculation method was established.The system consists of current signal acquisition unit,current signal transmission unit and remote integrated information management unit,which adopted GPRS for data transmission.Finally,the corresponding simulation model was built in the Matlab/simulink platform,which verified the validity of the system.
