Analysis of relationship between faults and outer surface temperature of oil-immersed power transformer

  • 摘要: 采用“部件-故障原因-温升现象”的3层结构对油浸式电力变压器故障进行了分类,总结了各类故障产生的原因,分析了各类故障对变压器外表面温度变化的影响。结果表明:铁芯及夹件、绕组及引线、分接开关、绝缘系统和油箱及底座等故障都会引起变压器外表面温度升高;冷却系统故障必然导致变压器外表面温度升高;一部分进出线套管故障会引起变压器外表面温度升高;大多数保护和测量装置故障会引起变压器温度升高。从而得出了油浸式电力变压器故障与其本体外表面温度的初步关系,即变压器故障大多会导致变压器外表面温度升高。
    Abstract: Different faults of oil-immersed power transformers were classified with three-layer structure of 'parts-fault causes-temperature rising phenomeno' and the fault causes were summarized, impacts of the different faults on outer surface temperature of transformer were briefly analyzed. The results show that fault will lead to outer surface temperature rising which including iron core and clamping pieces, winding and leading wires, tapping switch, insulation system, tank and base of the transformer; the faults of cooling system inevitably lead to outer surface temperature rising; part of bushing failures of outlet and inlet line will cause outer surface temperature rising of the transformer; most of failures of protection and measurement device will cause temperature rising of the transformer. Thus the preliminary relations between faults and its outer surface temperatures of the oil-immersed power transformer were obtained, namely most faults of the transformer will lead to outer surface temperature rising.
