Abstract
The utility model discloses a metallized film power capacitor which comprises a shell body, a wiring terminal and a capacitor core, the dielectric material of the capacitor core is a polypropylene film, wherein a layer of zinc-aluminum composite metal film is formed on one surface of the polypropylene film by a method of vacuum evaporation. By adopting the embodiment of the utility model, as the zinc-aluminum composite metal film with smaller volume resistance is used, only the self-healing property of the metallized film power capacitor is ensured, but sufficient current carrying capacity of a polar plate is also ensured, simultaneously the resistance of the polar plate is decreased and the heating value of the capacitor is reduced.
Description
Technical field
The utility model relates to electric elements, relates in particular to a kind of metallized film power capacitor.
Background technology.
The metallized film power capacitor has had the history of decades, and is domestic since the seventies and eighties in last century introducing production equipment and technology, because metallic film capacitor has self-healing function, therefore obtains rapidly promoting.Plate material has experienced from pure zinc-fine aluminium--the process that zinc-aluminium is compound.The zinc-aluminium composite membrane obtains owing to having taken into account self-healing property and non-oxidizability using gradually.
Metalized film power capacitor in the market adopts side's resistance span R=6～10 Ω/ of zinc-aluminium composite membrane.The metalized film of above-mentioned side's resistance has self-healing function, but because square resistance is big, the metalized film layer thickness is little, pole plate resistance is big, thereby make that the live stream ability of metalized film is relatively poor, the pole plate caloric value is big, temperature rise during the capacitor operation, thereby influenced life of capacitors, the miniaturization of capacitor volume also is restricted.
Side's resistance is exactly a square resistance, refer to a foursquare thin film of conductive material while arriving the resistance between " it ", square resistance has a characteristic, promptly the square resistance while arriving of size all is the same arbitrarily, no matter the length of side is 1 meter or 0.1 meter, their side's resistance all is the same, and this sample prescription resistance is only relevant with the factors such as thickness of conducting film.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model embodiment provides a kind of metallized film power capacitor, can reduce pole plate resistance, has reduced the caloric value of capacitor.
The utility model embodiment provides a kind of metallized film power capacitor, it comprises housing, binding post and capacitor body, the dielectric material of described capacitor body is a polypropylene film, and the wherein one side of polypropylene film has the zinc-aluminium composite metal membrane of one deck by the method formation of vacuum evaporation.
Further, the one end margin zone of described zinc-aluminium composite metal membrane is the metallic diaphragm thicker region, and the width of thicker region is 4～6mm, and other end fringe region is for staying edge regions, staying the edge regions width is 2～2.5mm, and the zone line of described zinc-aluminium composite metal membrane is the zone of action.
Further, the square resistance in the margo zone of described zinc-aluminium composite metal membrane is 2～4, and the square resistance in intermediate active zone is 5～7.
Adopt the utility model embodiment, owing to used the less zinc-aluminium composite metal membrane of square resistance, so both guaranteed that metallic film capacitor had good self-healing performance, guaranteed that again pole plate has enough current capacities, reduce pole plate resistance simultaneously, reduced the caloric value of capacitor.
