基于超高压变电设备缺陷特征的状态检修提升策略

Promotion Strategy of Condition Based Maintenanc Based on Flaw Characterization of Extra － high Voltage Substation Equipment

摘要:

在提倡清洁能源、水电消纳的背景下，结合四川电网的独特性，阐述了四川状态检修开展情况、带电检测发展 现状，指出状态评价中存在的问题。基于近 3 年带电检测结果，通过分析缺陷与地形、负荷、雷击分布、设备运行年限、 设备类型的特征关系，提出变电设备状态检修策略提升的建议，分别从数据应用、检修检测、设计采购、设备运维几方 面进行了阐述。

Abstract:

In the context of promoting clean energy and hydropower consumption，the development status of condition based maintenanc and charged detection in Sichuan is described combined with the uniqueness of Sichuan power grid． The problems in equipment condition evaluation are also pointed out． According to the achievements of charged detection in last three years， the suggestions of promotion strategy are proposed for condition based maintenanc through the analysis of the defects characteristic relation between defects and terrain，load，lightning stroke，operation life and equipment type． These suggestions include data application，maintenance，inspection，design purchase and equipment maintenance operation．
