State Maintenance For The Electric Equipment Of Power Plant

Current power generation equipment maintenance system can be divided into troubleshooting and planned maintenance (including inspection of fixed equipment in operation) of two. The two ways to repair power plants brought a lot of drawbacks, the randomness of a large overhaul. and with the development of power market reform, power generation business efficiency and stability of the units have become increasingly demanding, this maintenance methods can not meet under the enterprise development, and this situation there is considerable room for improvement.For power generation companies of this maintenance in this current status, this paper from the "state maintenance" in terms of equipment maintenance and repair are discussed, the purpose of seeking such a change for that too passive, lack of maintenance mode, early detection of equipment defects, accidents to avoid the appearance of equipment to improve equipment reliability, but also thereby increasing the effectiveness of equipment maintenance and economy. To explore this maintenance mode is mainly dependent on installation, commissioning, operation and other information and data in each period for equipments, also parameters, on-line testing, off-line detection methods and means to calculate, predict the device may occur at a time failure, in the and make the targeted for repairs. In the study to "state maintenance" method, at the same time, the paper also attempts to explore at this new maintenance mode, the power companies how to adapt, change and improve their level of equipment management, and equipment management personnel how to improve the overall technical quality, also more better adapt to the new maintenance mode of production management.The power plants in selected representative devices, including large oil transformers, generator and motor, the status of these devices is relatively large impact on power production. The failure rate of them is high. And the failure of them in performance, form and cause are more typical.So they would be used as objects of state maintenance.
