Abstract
The safe film technology is widely used in metalized film capacitor to provide protection for the metalized film capacitor and
to a certain extent
prevent occurrence of self-healing failure.For metalized film capacitor used in the field of AC or pulse discharge
the thermal effect can not be ignored because of the extremely thin metal electrode and large electrode resistance.At present
the safe film in wide application is roughly classified into such two types as T pattern and grid pattern.As for above two kinds of metalized film structure
their ESR(equivalent series resistance)is calculated and they are compared with general metalized film
which provides a definite reference for the operation feature analysis of capacitor adopting safe film structure.
