摘　　要：根据两起变压器油色谱在线监测装置发现的异常数据案例,通过离线油色谱取样分析、铁心夹件接地电流监测和停电解体检查等手段,发现变压器内部过热和局部放电等缺陷,变压器油色谱在线监测装置在主变缺陷预警和监测方面具有积极作用。According to two cases of abnormal data found by transformer oil chromatography online monitoring device,the defects of transformer internal overheating and partial discharge are found through analysis of offline oil chromatography sampling,groundingcurrent monitoring of transformer core and clamping,disassembly inspection in power outage condition,etc.,which show that transformer oil chromatography online monitoring device plaied an extremely important role in the early warning and monitoring of main transformer defects.
