新型变压器在线监测与诊断系统技术及其应用-法拉第TNU诊断系统在安顺换流站的应用

The New Technology and Its Application in On-line Monitoring and Diagnoses System for Power Transformer

论述了利用法拉第TNU变压器在线监测诊断技术判断变压器内部潜伏性故障的原理,介绍了油色谱综合智能在线监测系统在安顺换流站带故障换流变压器上的应用。通过典型实例中对在线监测数据与离线测试数据的比较分析,验证其准确性,显示了使用该技术预测、判断变压器故障的重要性,为电力系统由计划检修向状态检修过渡提供了一种较好的手段。

This paper discusses a method to detect the internal latent fault by using Faraday TNU On-line Monitoring Technology. The Intelligent Oil Chromatography On-line Monitoring System serviced in Anshun Converter Station is introduced. In order to verify its accuracy, some typical cases is used by analyzing and comparing the on-line monitoring data with the off-line monitoring data. The results show that it is important of forecasting and judging the internal fault by this method, and the method provides a better way to change the maintain rule of power system from the planned overhaul to the state overhaul.
