摘要
此文介绍了红外热像检测中,某110 kV油浸式电流互感器顶部膨胀器外壳因材质辐射率影响的案例,分析了不同金属材质影响下的红外测温结果,并提出了相应处理的措施。
This paper has introduced a typical case,of which the top extender shell of a 110 kV oil immersed current transformer is influenced by material emissivity when giver test of infrared thermography. Also analyzed is infrared temperature measured result under the influence of different metals. And measures to prevent erroneous .judgment are proposed.
