Abstract
How to ensure the safe and stable operation of power system is one of the key tasks that need to be solved urgently in power department at present, and the fault factors such as normal operation and condition maintenance of power transmission and transformation equipment determine the safety of power system. In order to solve the fault diagnosis method of transmission and transformation equipment, improving the efficiency of equipment condition maintenance and improving the ability of fault discrimination is one of the main solutions. In this paper, through the equipment state evaluation and fault early warning based on-line monitoring, a variety of inspection measures are fully considered through the model, so as to predict the equipment with hidden trouble and put forward the fault early warning.
