[Abstract]:With the rapid development of power system automation, the requirement of power supply reliability is increasing day by day. The requirements of safety, economic benefit and reliability of important electrical equipment in power transformer-power system are also higher and higher. In order to meet the requirements of the current situation for the power system, it is necessary to develop intelligent on-line detection methods and fault diagnosis strategies. The application of on-line detection technology and mature fault diagnosis technology can greatly improve the safety and reliability of substation primary equipment, prolong the safe service life of substation equipment, and improve the utilization ratio of substation equipment. Therefore, the old-fashioned preventive maintenance system has been gradually replaced by the condition-based maintenance system based on on-line detection and fault diagnosis research technology. This paper analyzes the faults and monitoring principles of substation main transformer, high voltage circuit breaker, capacitive equipment and zinc oxide arrester, studies the application scope of various monitoring principles, and emphasizes on understanding several online monitoring techniques which are widely used at present. Compare and analyze the on-line monitoring technology of transformer, circuit breaker, capacitive equipment and zinc oxide arrester, and study the engineering application of on-line monitoring technology. The advantages and disadvantages of online monitoring technology and the practical application of the points of attention are analyzed in detail. The state evaluation method and fault diagnosis technology of primary substation equipment are analyzed and studied. The research on the status assessment method, fault diagnosis technology and the key technology of condition-based maintenance lays a solid foundation for the subsequent development of condition based maintenance. In this paper, the theoretical and practical application of on-line monitoring and fault diagnosis is studied. Through the analysis and discussion of the difficulties in the theory and practice of condition-based maintenance, the working methods of condition-based maintenance suitable for substation equipment are summarized.
