    Abstract: The major equipment hazards could be successfully discovered and interfered with the infrared imaging technology used in the nuclear power plant during the operation of multiple transformers.Introduction was made to the experience and method of infrared imaging technology in daily operation and maintenance of nuclear power transformer through some specific cases.This paper concretely analyzed that the application of infrared imaging technology could diagnose the overheating flange bolt in ascending flanged base of transformers lowvoltage drivepipe and the outside bin of transformers low-voltage drivepipe could be measured to discover the overheating electric connection of drivepipe, so as to diagnose that the oil level abnormity warning of transformers expansion tank was truth and to discover the circulation overheating ablation of transformers fire annihilator pipe etc cases.This paper proposes the attentive matters in the application process of
infrared imaging technology.
