摘要
为提高电力系统的安全性,将接地线电流法作为核心方法,设计电力电缆绝缘在线监测系统。采用通用分组无线业务/码分多址(General Packet Radio Service/Code Division Multiple Access,GPRS/CDMA)通信方式作为电力电缆绝缘在线监测系统的核心,建立电缆各条线路之间的通信连接。利用电流互感器(Current Transformer,CT)检测电缆电流变化情况,有利于提高绝缘在线监测系统的检测精度。将绝缘在线监测应用于电力系统,可为电力系统的后续发展提供依据。
In order to improve the safety of power system,the on-line monitoring system of power cable insulation is designed with grounding wire current method as the core method.The communication mode of General Packet Radio Service/Code Division Multiple Access(GPRS/CDMA)is adopted as the core of the on-line monitoring system of power cable insulation,and the communication connection between various lines of the cable is established.Using Current Transformer(CT)to detect the change of cable current is beneficial to improve the detection accuracy of insulation on-line monitoring system.The application of on-line insulation monitoring in power system can provide basis for the subsequent development of power system.
