油浸式变压器在线检测与故障诊断技术研究

Research on Online Detection and Fault Diagnosis Technology for Oil Immersed Transformers

通过对油浸式变压器故障类型及诊断方法进行详细研究,并结合变压器油色谱分析、局部放电检测及温度检测等技术设计了一套电力变压器监测及故障诊断系统。该系统可实现对油浸式变压器的全方位在线检测及故障报警诊断,同时兼顾检测快速性及准确性,有效提高油浸式变压器检测的智能化程度。

Based on a detailed study of the types and diagnostic methods of faults in oil-immersed transformers,and combined with techniques such as transformer oil chromatogram analysis,partial discharge detection,and temperature detection,the author has designed a power transformer monitoring and fault diagnosis system,which can achieve comprehensive online detection and fault alarm diagnosis of oil-immersed transformers,while also considering the speed and accuracy of detection,effectively improving the intelligence level of oil-immersed transformer detection.
