The invention relates to a wireless intelligent sensor network system for monitoring states of intelligent substation devices. The system is overall divided into a transformer substation level state monitoring system and a dispatching center level state monitoring system, the transformer substation level state monitoring system is divided into a sensing layer, an accessing layer and an application layer, an intelligent sensor on the sensing layer is responsible for collecting image and scalar data, and transmitting information to a monitoring center platform on the application layer through the accessing layer, and key information is transmitted to a dispatching center monitor integration platform through an electric power data communication network. A self-organization and self-recovery wireless substation device monitoring network is established to replace traditional wired ways, so that hierarchical distribution co-processing of data is achieved, communication load balancing capacity of the monitoring network is improved, wiring difficulties of installation are reduced, installation costs of transformation and upgrade of the substation devices are reduced, flexibility and use ratio of the monitoring network system are enhanced, overall assessment of operation conditions of the substation devices is enhanced, and fault hidden dangers of the devices can be timely found and eliminated.
