Study On Power Transmission Line Condition Based Maintenance

Performing the preventive experiment and preventive maintenance periodically is the traditional approach in maintaining power transmission lines, making the unnecessary waste of manpower and resources. While performing preventive maintenance in accordance with the condition of the equipment instead of the periodical time is the advanced method of explore in maintaining power transmission lines.Along with the development of power industry and the improvement of the level of the equipment automation and reliability, we propose the strategy of status maintenance, a scientific maintenance management method which is based on diagnosis forecasting. Besides, it is also a standing-out approach of affirmable maintenance period and project which is under the guidance of advanced maintenance and test technology and systemic analysis in operation experience and data of in maintaining power transmission lines.First it introduces what status maintenance is as well as some other standing-out online monitoring systems. Then it talks about how to integrate the method with practice of PingDingShan Power Supply Company in HeNan, how to utilize the current available resources to find ways of how to perform status maintenance in practice uses. In the last part of the file the prospect of status maintenance is forecasted and online monitoring technology and the relationship of status and preventive maintenance is also presented.Firstly,It introduces the concept of status maintenance and process of status maintenance.Then, the principal and content of status maintenance, the ways of online monitoring technology, the test technology of status maintenance,the problems of practical status maintenance, and the information system of status maintenance are studied.Finally, it talks about how to perform status maintenance for power transmitting lines in accord with the rules for implementation of Electric Power of HeNan and with practice of PingDingShan Power Supply Company and discusses.In the last part of the file the conception of the system of status maintenance for power transmitting lines and the direction for further improvement are presented.
