an 710049, China) Abstract: As more information technologies have been utilized in power equipment and power system,intelligent electrical equipment came into being and have been developing rapidly. The intelligent electrical apparatus has the function of digitalizing and monitoring the electrical parameters to implement judgement and then control and protect the supervised objects in a smart way, besides self?monitoring, self?diagnosing and protection. It is more reasonable to analyze and determine the condition of in?service power equipment and take a predictive maintenance by using the life?cycle management method, so as to improve the reliability and safety of the whole electrical system. It becomes an unreversed tendency to implement the life?cycle management of power equipment, through processing the online monitoring parameters of power equipment with the big data related technologies. In the future, the manufactures of power equipment should provide overall and profound services for their customers, that is, to become service provid? ers,not just provide the physical products of power equipment,with acquiring the running parameters of power equipment by internet of things and analyzing the lifetime state of them based on big data technologies.
