变压器油色谱在线监测装置运行故障分析
Operation Fault Analysis of Transformer Oil Chromatography On-line Monitoring Device
摘要
Abstract
In order to study the causes of malfunction of the transformer oil chromatography online monitoring device during operation,the on-line monitoring device in a UHV substation was analyzed.In this case,the transformer oil acetylene exceeded the standard,but acetylene was undetected.And then on-site inspection,test detection and other ways were adopted to confirm that the failure cause of monitoring devices using gas chromatography principle was the detector problem,and the malfunction of the photoacoustic spectroscopy principle device was caused by the acetylene sensor communication problem.The fault phenomena of two kinds of principle on-line monitoring devices are verified by experiments.It is suggested that the manufacturing process should be optimized in the later stage,the self-check function should be added to the online monitoring device,and the fault alarm list should be improved aslo.When abnormal situation exists,the online monitoring device can respond timely and remind operation and maintenance personnel to maintain the device.关键词
