摘　　要：提出了基于嵌入式微机系统的总线式结构的变电站绝缘在线监测系统 ,其模拟信号的提取和采集、数字信号的分析和处理以及通信均由现场监测单元完成 ,可真正实现绝缘参数的就地测量 ,避免了模拟小信号的远距离传输 。A RS485 bus model on line insulation monitoring system for high voltage apparatus in substation is presented. Its realization is based on the development of embedded micro computer unit. Coupling, A/D and processing of signals and communication are implemented by every micro\|computer unit and insulation parameters are measured locally. The long distance transmission of small analog signals is avoided, thus the anti interference ability are outstandingly improved and a high stability of the monitoring system is realized.
