摘　　要：提出了基于NT平台的网络型结构的绝缘在线诊断系统 ,以SQLServer作为数据库服务器 ,对系统信息采用分布式管理方式运用智能技术进行绝缘诊断 ,实现了数据库资源和专家知识的共享。以工业级 32位微处理器为基础研制的RS485总线结构绝缘在线监测系统实现了绝缘参数就地测量 ,使其抗干扰性及测量准确性、稳定性大为提高。A network model on line insulation monitoring and diagnosis system for HV apparatus in substation is developed. A RS485 bus model online monitoring system based on embedded 386EX micro computer system is presented first. The anti interference ability of the monitoring system is increased by measuring insulation parameters locally. A network model online insulationdiagnosis system, which is based on client/server system, is then developed. Some intelligent methods are applied for online insulation diagnosis.
