The present invention discloses an intelligent state identification system for extra-high-voltage (EHV) electric transmission and transformation equipment. The system is characterized by comprising a super capacitor for charging a storage battery and powering on a camera; and a solar cell panel connected with the super capacitor and used for charging the super capacitor. The camera is in communication with a server through a communication module. The server is in communication with a client through a network line. The camera and the storage battery are electrically connected with the communication module. The communication module is in communication with the server through a wireless signal. By means of the super capacitor and the solar cell panel, the camera is powered on. During the fault of a power transmission line, the electric energy stored in the storage battery is used for monitoring and sending a video signal. Therefore, the reliability of a monitoring system is ensured.
