To achieve the above object, the utility model provides a kind of self-healing metallic film capacitor, including capacitor
Fuse and lead positioned at the capacitor body both ends, the capacitor body is by A film and B film is noninductive rolls, institute
State the coat of metal one that A film includes substrate one and is arranged on the substrate one, the coat of metal one is from centre to both sides
It is gradually thinning, and one both sides of the coat of metal are provided with Bian Liubian, the B film includes substrate two and is arranged in the base
The coat of metal two on material two, the coat of metal two is gradually thinning from both sides to centre, and sets among the coat of metal two
It is equipped with an intermediately remained border.
Preferably, the width of the Bian Liubian is set as 2.5-3mm, and the width of the intermediately remained border is set as 4-6mm.
Preferably, the intermediate position of the coat of metal one is parallel to each other with the substrate one, and the intermediate position
Width is less than the width of the intermediately remained border, and the end face on the intermediate position both sides is disposed as convex arch, the coat of metal
Two end face is set as concave arc shape.
Preferably, the width of the A film is less than the width of the B film.
Preferably, the material of the substrate one and the substrate two is polypropylene, the coat of metal one and the gold
Belonging to coating two is zinc-aluminium complex metal layer.
Therefore, the self-healing metallic film capacitor of the utility model using the above structure, the coat of metal one and metal
The thickness of coating two is gradual change, improves the overcurrent capability of capacitor, the capacitor body after the completion of rolling, the film side A
Low region is hindered, B film sheet resistance is high, and the high region of A film sheet resistance, B film sheet resistance is low, guarantees the self-healing property of metallic film capacitor.

Specific embodiment
Embodiment
Fig. 1 is the schematic diagram of the utility model self-healing metallic film capacitor embodiment, Fig. 2 be the utility model from
More the schematic diagram of the A film of formula metallic film capacitor embodiment, Fig. 3 are the utility model self-healing metallic film capacitors
The schematic diagram of the B film of embodiment.As shown, the utility model provides a kind of self-healing metallic film capacitor, including
Capacitor body and lead positioned at the capacitor body both ends, the capacitor body by A film and noninductive roll of B film and
It include substrate 1 and the coat of metal being arranged on substrate 11 at, the A film, the coat of metal 1 is from centre to both sides
Gradually thinning, it is big to show as both sides sheet resistance, is gradually reduced from both sides to intermediate sheet resistance, one 2 both sides of the coat of metal are provided with side
Side 3 is stayed to prevent metallic particles from entering the A film, with institute when the later period carries out metal spraying processing to the both ends of the A film and the B film
One 2 adhesion of the coat of metal for stating A film, causes short circuit, and 3 width is set as 2.5-3mm when staying, and increases creepage distance, mentions
High partial discharge performance；The B film includes substrate 24 and the coat of metal being arranged on substrate 2425, the coat of metal 25
