Research And Application Of The Electrical Equipment On-line Monitor And Condition-based Maintenance Technology In Canton Fair Exhibition

Currently,along with the trend development of exhibition industry, the exhibition also gradually move toward large-scale, modern, in case of power off will result in significant impact and the loss, the major exhibition venues of power system reliability requirements have been increased.Preventive tests failed to completely reflect the true condition of the equipment, equipment maintenance should be a gradual transition of PM(preventive maintenance) and CBM(condition-based maintenance) combined. In order to achieve maximum economy ,through DGA(dissolved gas analysis), PD(partial discharge), infrared radiation monitoring of economic, practical on-line monitoring technology, according to data obtained from monitoring techniques, using appropriate diagnostic techniques for data analysis, grasp the equipment status, revise the test cycle of PM(preventive maintenance)or the number of test equipment .This dissertation that starts from the technology and management optimization and improvement of on-line monitor and CBM(condition-base maintenance),combining with Canton Fair Exhibition actual operation and maintenance experience, analyses and make researches on the principles, technology characters, and applications of DGA(Dissolved Gas Analysis)of transformer oil, PD(Partial Discharge)of GIS, infrared monitor and diagnosis. Through large transformers, GIS switching and other important equipment on-line monitoring and diagnosis for case study. Basing on CBM(condition-based maintenance) strategy combined with RCAM(Reliability Centered Enterprise Asset Maintenance Management), to further improve equipment management system and platform, and following the application of analysis and research.Through this topic we optimize the power equipment maintenance management model of Canton Fair Exhibition, enhance equipments operation security and reliability, reduce the maintenance expenses. This research achievements could as the CBM(Condition-Base Maintenance)reference of large venues,it also provide some technology and experience reference for other Power Stations and Electric Power Supply Bureaus on high voltage electrical equipments in practical operation and maintenance.
