| SF6 circuit breaker is a technically mature high-voltage electrical equipment, and many of its performance are significantly better than the original oil circuit breaker, the recent 10 years in the country to obtain a large area applications. SF6 circuit breaker Interrupter performance is good, high insulation fracture. SF6 decomposition after compound does not break down the harmful carbon and other insulating materials, strict control of moisture in the circumstances, the resultant non-corrosive. SF6 Gas Insulated not fall, so many times to allow SF6 breaking, overhaul a long cycle. No matter the size of current interrupting, SF6 interrupter effects are good. SF6 high thermal conductivity, allowing current big. SF6 gas due to the interrupter and insulation with excellent performance, the 20th century, has been successfully applied to high-voltage electrical appliances, thus causing high-voltage electrical equipment in a major innovation. SF6 range of applications in virtually through pressure, high pressure and ultra high voltage electrical equipment. There is no media in the near future is expected to be comparable with, especially in high-voltage and extra high voltage range, SF6 is still the only choice of the medium; medium pressure range, vacuum circuit breaker to be the rapid development of partial replacement of the SF6 circuit breakers, SF6 circuit, but device because of its open-off over-voltage is low, it is still the choice of species, and SF6 load switch, ring main unit, inflatable cabinet rapid development of SF6 in the pressure field is also room for consolidation and development.Currently in Daqing Oil Field as well as domestic, SF6 circuit breakers have been widely used, but because there is no uniform technical standards, in the application, there are some problems such as the specific parts needed lubrication, due to North-South climate and environment caused by differences in Lubrication cycles are different; as well as the circuit breaker overhaul cycle, what and when to overhaul; maintenance test items and standards; common treatment failures and so on. In this paper, full study of the domestic manufacturers on their production of SF6 circuit breaker performance and structure of the introduction, operation and maintenance requirements, and in the light of foreign experience in the same industry after the repair and maintenance is proposed for domestic characteristics of SF6 circuit breaker maintenance process standards, the major domestic manufacturers of SF6 circuit breaker structure and performance of a comprehensive comparison and analysis of the overall structure of SF6 circuit breaker and interrupter theory, action theory are set forth on the transfer of SF6 circuit breaker items and standards of acceptance , SF6 circuit breaker maintenance of test equipment required, SF6 circuit breakers and standards for the transfer of pilot projects, SF6 circuit breaker maintenance overhaul cycles, Maintenance and Repair of technology and quality standards and methods commonly used replacement parts and so gives a perfect standard, At the same time, combined with my many years of experience in maintenance of SF6 circuit breakers, SF6 switch to the alpine region had experience in repair and maintenance summary of the typical defects of the SF6 circuit breakers, and how to deal with the judgments made in detail, the last of the SF6 gas hazard and prevention are described. In this paper, to guide the domestic repair and maintenance...
