Description
Technical field
The utility model is related to a kind of metallic film capacitors of withstanding current capability, belong to power electronics field.
Background technology
Metallized film capacitor is to replace metal foil as electrode in the surface of polyester film vapor deposition layer of metal film, because
For layer of metallized film thickness be much smaller than metal foil thickness, therefore wind after volume also it is more small than type metal foil type capacitance very
It is more.The great advantage of metalized film capacitance is " self-healing " characteristic.If so-called self-healing feature is exactly thin film dielectrics due in certain point
Existing defects and there is puncture short under overvoltage effect, and the metal layer of breakdown point can be melted in moment under arcing
Change evaporation and formed very little without metal area, make two pole pieces of capacitance again mutually insulated and remain to work on, because
This greatly improves the reliability of capacitor work.Existing tolerance high current ability is poor, influences the normal work of capacitor, makes
Use short life.
