摘要(Abstract)：

在分析油浸式电力变压器的负载、绝缘特性的基础上,开发了基于PI数据库的变压器绕组绝缘分析系统。该系统利用PI数据库中变压器的负荷数据,对绕组的热点温度进行实时监测,对一段历史时期内绕组的绝缘老化情况进行评估。系统的投运为供电企业提供了掌握变压器内部绝缘状况的工具,为变压器的科学运维提供了积极的帮助。
Through the analysis of the load and insulation characteristics of oil-immersed transformers,an insulation analysis system for transformer windings based on plant information(PI) database is developed,which uses the transformer load data in PI database for real-time temperature monitoring of the heat spots of the windings and evaluation of insulation aging of the windings during a historical period.The system provides power supply companies with a tool to understand the situation of internal insulation of transformers and helps with scientific operation and maintenance of transformers.
