Abstract

The invention is applied to the technical field of fault detection, and provides a power equipment fault diagnosis method and device, and terminal equipment. The power equipment fault diagnosis methodcomprises the following steps: obtaining initial fault information of the power equipment sent by the terminal equipment, and searching for a corresponding initial predicted diagnosis result in a pre-stored fault information database according to the initial fault information; judging whether the initial predicted diagnosis result satisfies a first preset rule or not; and if the initial predicteddiagnosis result satisfies the first preset rule, obtaining fault detection prompt information according to the initial predicted diagnosis result, obtaining fault detection supplemental informationsent by the terminal equipment, and determining the final fault diagnosis result of the power equipment according to the fault detection supplemental information and the initial fault information. According to the invention, through inputting the initial fault information, the diagnosis result can be obtained automatically, and the efficiency of fault diagnosis can be improved; meanwhile, the first preset rule is used for screening the initial predicted diagnosis result, which improves the accuracy of the fault diagnosis method, and avoid the phenomenon that too many diagnosis results are obtained and the maintenance idea of the maintenance personnel is disturbed.
