Abstract Accurate monitoring of electrical equipment temperature can effectively ensure the safety of electrical equipment operation. It is worth further study to use limited temperature monitoring equipment to obtain a comprehensive temperature distribution of electrical equipment. Based on the study of nearest neighbor interpolation bilinear interpolation and bicubic interpolation these three methods are applied to image processing of temperature distribution in 10kV switchgear cabinets. Compared with the three methods, bilinear interpolation and bicubic interpolation can accurately reflect the non-measured temperature, and can be used in image processing of temperature distribution in high-voltage switchgear temperature measurement system.
