【摘要】 变压器绝缘状况的优劣是电力系统安全运行的关键因素之一。常规的实验室油色谱分析法存在一些不足之处,提出了变压器油中溶解气体色谱分析的在线监测方法,该方法具有很强的时效性。阐述了色谱分析在线监测装置的必要性和该装置的作用,以及基本技术要求和评价方法,指出具有多功能的油中溶解气体在线监测及智能诊断装置最终将取代常规的离线油中气体色谱分析。更多还原

【Abstract】 Insulation state in transformers is one of the key factors affecting safe operation of the electric power system.Owing to some insufficiencies existing in conventional chromatographic analysis of oil in laboratory,an on-line monitoring method effectiveness of time for chromatographic analysis of dissolved gases in transformer oil has been put forward.The necessity and effect of on-line monitoring facility for transformer oil,as well as basic technology and evaluation method have been expounded,pointing out that the multi-functional on-line monitoring for dissolved gases in oil and intelligent diagnosis facility will finally replace the conventional off-line chromatographic analysis of gases in oil.更多还原
