运行中500 kV变压器油质状况及运行前景分析

Analysis of Quality Condition and Operation Prospect for 500 kV Transformer Oil

对11台由不同国家生产的500kV变压器及其进口油和国产油的理化性能及运行情况进行了分析和比较,对国产油与进口油混合问题进行了较全面的分析研究。为今后时500kV变压器油的补油和换油问题、500kV设备和油今后可能发生的各种变化和设备隐患分析以及500kV变压器油的监督和管理提供了比较完整的分析数据。

This paper analyzed the physical and chemical performances and operation condition of transformer oil from 11 transformers of 500 kV, which imported or home made by different countries. The oil mixed problem for the imported oil or that made in China was carried out more overall analysis. The paper offered the analysis with complete comparison data for the future for mending and changing 500 kV transformer oil, the various changes and the hidden trouble analysis of equipments as well as the supervision and management for 500 kV transformer oil.
