Analysis on Reliability of Main Connection of Traction Substation Considering Influence of Maintenance
摘要
Abstract
Reliability of traction substations directly relates to the security of railway transportation, and maintenance is one of important factors influencing reliability of traction substations. To analyze the influence of maintenance on reliability of traction substation, two reliability models for traction substation are built under un-maintainable and maintainable conditions respectively, and the methods to calculate the mean time between failures （MTBF） and mean time to first failure （MTTFF） of the two proposed models are given. Calculation results show that the MTBF of maintainable main connection of traction substation is evermore greater than its MTTFF; the MTBF of maintainable main connection of traction substation is evermore greater than its MTTFF under un-maintainable condition; the comparison results between the MTBF under maintainable condition and the MTBF under un-maintainable condition depend on the value of component maintenance rates.关键词
