Abstract

Power electronic capacitor for rail transit has such advantages as small size

high designed field strength

long prospective life and is suitable for application in complicated conditions and severe environment.To ensure safe and reliable operation of vehicles

the long time accelerated aging test is performed on the prototype capacitor and its life expectancy is deduced.The actually measured data of capacitor after operation of 4.8 million kilometers is studied and analyzed.It is proved throughout study that the capacitor for rail transit is safe and reliable and has long life.Moreover

the feasibility of improving maintenance interval is validated further.
