摘要

GIS的可靠性统计表明

电气故障最通常的故障特征是在完全击穿前发生局部放电。论文总结了目前国内外关于GIS局部放电测试技术及其特点

尤其针对局部放电特高频在线监测技术的应用

重点阐述了内置式局部放电UHF传感器的布置方法及应用效果

并结合南方电网的发展趋势

提出了目前在数字化变电站应用中存在的GIS局放测试系统与其他在线监测系统配合不够完善

存在多套系统并列运行等问题

建议在设备选型时考虑局放测试系统与在线监测主系统由同一供应商研发。

Abstract

GIS reliability statistics show that the most common electrical failure is characterized by a partial discharge occurring before the complete breakdown.The paper summarizes the present GIS partial discharge testing techniques and their characteristics

especially the application of the UHF method for partial discharge on-line monitoring

mainly focusing on the placement of the internal UHF sensors and its application effect.Combined with the development trend of China Southern Power Grid

the paper also points out the problem like GIS partial discharge monitoring system not matching well with the other on-line monitoring system and several systems running in parallel.And therefore

it suggests both the partial discharge monitoring system and its major on-line monitoring system should be developed by the same supplier.
