T pattern metallized safety film capacitor not only has self-healing performance of general selfhealing capacitor

the secondary protection action provided by its modular electrode prevents further development of self-healing failure

and the temperature variation caused by structure change in electrode greatly affects the operation performance and lifetime of capacitor.In this paper

on the basis of introducing the internal heat generation and dissipation

the temperature field of T pattern metallized safety film capacitor with ANSYS Workbench 15.0 is simulated so to explore the ratio of fuse width and segment width

influence of ambient temperature on the highest temperature of the capacitor

deduce the corresponding relationship between various influence factors and the highest temperature and provide calibration method for the key dimension designation of T pattern metalized safety film capacitor.
