【摘要】：采用"部件-故障原因-溫升現(xiàn)象"的3層結(jié)構(gòu)對油浸式電力變壓器故障進(jìn)行了分類,總結(jié)了各類故障產(chǎn)生的原因,分析了各類故障對變壓器外表面溫度變化的影響。結(jié)果表明:鐵芯及夾件、繞組及引線、分接開關(guān)、絕緣系統(tǒng)和油箱及底座等故障都會引起變壓器外表面溫度升高;冷卻系統(tǒng)故障必然導(dǎo)致變壓器外表面溫度升高;一部分進(jìn)出線套管故障會引起變壓器外表面溫度升高;大多數(shù)保護(hù)和測量裝置故障會引起變壓器溫度升高。從而得出了油浸式電力變壓器故障與其本體外表面溫度的初步關(guān)系,即變壓器故障大多會導(dǎo)致變壓器外表面溫度升高。
[Abstract]:The 3 layer structure by reason "part of fault - temperature rise phenomenon" the classification of oil immersed power transformer fault, summarizes the reasons of fault, analyzes the influence of all kinds of faults on the surface of the transformer temperature changes. The results show that the iron core and clamps, and winding wire, switch, insulation system and the fuel tank and the base fault will cause the surface of the transformer temperature; cooling system failure will inevitably lead to the surface of the transformer temperature rise; a part of inlet casing fault will cause the surface of the transformer temperature rise; most of the protection and measurement device failure will cause the temperature of the transformer is obtained. Preliminary oil immersed power transformer fault and its relationship the outer surface temperature, the transformer fault mostly leads to the surface of the transformer temperature rise.
