An intelligent inspection system for electrical devices comprises the multiple electrical devices, an intelligent inspection mobile terminal, a remote data center management information system and an inquiring terminal, wherein each electrical device is provided with local data collecting sub-systems and positioning identification, and the local data collecting sub-systems are used for collecting running parameters of the electrical devices where the local data collecting sub-systems are located; the intelligent inspection mobile terminal is in communication connection with the local data collecting sub-systems and the positioning identifications through wireless communication, the corresponding local data collecting sub-system is started through the positioning identification to transmit the running parameters of the electrical device where the local data collecting sub-system is located to the intelligent inspection mobile terminal, and the running parameters serve as inspection data; the remote data center management information system is in communication connection with the intelligent inspection mobile terminal through wireless communication and receives, saves and manages the electrical device inspection data collected by the intelligent inspection mobile terminal; the inquiring terminal is in communication connection with the remote data center management information system through the Internet so that the historical inspection data of the electrical devices can be inquired. The intelligent inspection system can effectively improve the working efficiency, and overcome the problems that in a traditional inspection mode, manual entry of the inspection data is needed, the inspection data is input to the information management system not in time and efficiency is low.
