摘　　要：分析了目前变电站和发电厂中直流系统绝缘监察方法的不足 ,提出了一种基于 Lon-Works现场总线的直流系统分布式绝缘监察技术 。The shortcomings of the present insulation monitoring methods of DC system in the transformer substations and power plants are analysed.A new technology is put forward ,which is the distributed insulation monitoring technology of DC system based on LonWorks fieldbus. Real time and online insulation monitoring of every branch and device are realized by making use of this technology.Distributed technology can reduce the cable setting greatly.All the smart nodes can be connected only by two pieces of lines.Free topology makes the line free to connect,system easy to extend and simple to maintain.
