【 摘 要 】

Temperature measurement is critical for fault detection in electrical equipment. Non-contact infrared temperature measurement, with its fast, accurate, convenient, long life, and other advantages, has been widely used in the power grid. With the development of the times, infrared detection technology mature and increasingly sophisticated. Infrared detection technology not only has long-distance, non-contact, real-time and accurate features, but also in the non-power failure, no sampling, not disintegration of the case to achieve fault diagnosis and online testing. Here, examples of the use of infrared thermal imaging to detect abnormal heat generation method, which found that the defect and give the reasons for treatment recommendations and measures.
