Abstract
The utility model relates to a small-sized high-voltage foil-type film capacitor. According to the utility model, the core of the capacitor comprises two parallel aluminium foils, a polypropylene light film and a single-surface metallized polypropylene film; and the distance between leading pins of the capacitor is 7.5 mm. The capacitor has the characteristics of small size, high-voltage resistance, and high-current shock resistance, can be used in impulse and starting circuits, and can be particularly used as a small-sized high-voltage lamp capacitor.
Description
Technical field
The utility model relates to film capacitor.
Background technology
The capacitor plate of common minitype high voltage metallization film capacitor is the metal layer of vapor deposition on the polypropylene basement membrane; Because of the thickness of metal layer has only tens nanometer; Though this capacitor can be high pressure resistant, anti-rush of current is indifferent, on impulse circuit, needs control to use.
High its volume of blocking formula film capacitor is bigger, and the spacing of capacitor leading foot has limited use occasion more than 15mm.
The utility model content
The purpose of the utility model is to the deficiency of existing two kinds of capacitors, and a kind of minitype high voltage paper tinsel formula film capacitor is provided, capacitor has high pressure resistant, anti-heavy current impact, the characteristics that volume is little.
The technical scheme that the utility model adopts is: a kind of minitype high voltage paper tinsel formula film capacitor; Comprise capacitor body and leading foot; Leading foot is connected on the pole plate of capacitor body, it is characterized in that: said capacitor body is laminated to reel and is constituted by two aluminium foils that are arranged in parallel, a polypropylene light film, a single face metallized polypropylene film.
As the further improvement of the utility model, the thickness of above-mentioned aluminium foil I and aluminium foil II is 5 ~ 7 μ m, and width is 3mm; Aluminium foil I and aluminium foil II are arranged in parallel, and distance is 2mm.
Above-mentioned polypropylene light film thickness is 5 ~ 7 μ m, and width is 7mm, has better effect.
Above-mentioned single face metallized polypropylene film thickness is 5 ~ 7 μ m, and width is 7mm; The metal layer width of vapor deposition on the single face metallized polypropylene film is 5mm, and the film both sides of the edge respectively have the wide no metal level of 1mm to stay the border area.
The utlity model has following advantage:
1, the internal series-connection structure of capacitor makes capacitor can obtain very high proof voltage ability.Utilize fuse series connection capacity tolerance complementarity principle simultaneously, make that the capacity tolerance fluctuation reduces in the production process of capacitor, improved the yields that capacitor is made, reduced the manufacturing cost of capacitor.
2, aluminium foil can guarantee that as extraction electrode the anti-high current impulse withstanding capability of capacitor is strong, makes capacitor application in the circuit of pulse, Fraquent start.
3, current complete machine, particularly compact high-pressure discharge lamps have been satisfied, for capacitor small size, little spacing, high-tension specification requirement.
