Definitions

  • the invention relates to an electrical capacitor, in particular a stacked or layered capacitor, with an internal series connection and very low capacitance values, which consists of at least two plastic films arranged one above the other and provided with regenerable metal layers, in which the metal layers on the first plastic film up to both Edges extend and are separated from one another by a metal-free strip, in which the second plastic film has a smaller width than the first plastic film and is provided with separate metal layers which serve as a blind covering and cover the metal-free strip on the first plastic film and in which the end faces are contacted with flame-sprayed Schoop layers.
  • capacitors For extremely low capacitance values, capacitors have therefore hitherto been relied on, which consist of plastic foils and in which the electrodes are formed by aluminum foils.
  • regenerable capacitors cannot be regenerated and the entire capacitor is destroyed in the event of a short circuit. It is an object of the present invention to develop the regenerable capacitor mentioned at the outset in such a way that extremely low capacitance values are also obtained with regenerable capacitors.
  • the metal layers preferably have a circular or elliptical or a square or rectangular cross section.
  • capacitors with extremely low capacitance values can be produced by the embodiment according to the invention.
  • a regenerable capacitor with an internal series connection is already known, in which the blind covering consists of individual metal layers separated from one another, but these metal layers essentially cover the entire width of the plastic film.
  • the division of the blind covering in the known capacitor also does not serve to obtain particularly low capacitance values, but is intended to improve the insulation resistance, in particular at low voltages, and at the same time provide the possibility of being able to manufacture such capacitors with a small capacitance tolerance without any appreciable rejects.
  • metal layers 3, 4 for example made of aluminum, zinc or alloys with possibly other metals, are arranged in such a way that they reach the edges of the plastic film 1 are sufficient where they can be contacted with Schoop layers not shown in the figure.
  • the second plastic film 2 has a plurality of metal layers 5 which are separate from one another and which, according to the exemplary embodiment, have a circular cross section, but can also have other shapes, such as the cross section of an ellipse, a square or rectangle or other suitable cross-sectional shapes.
  • the metal layers 5 cover the metal-free strip 8, which is arranged on the film 1, only slightly.
  • a capacitor with an internal series connection is thus formed, which consists of two capacitor elements connected in series, namely between the metal layers 4 and 5 or 5 and 3.
  • a capacitor which consists of capacitors connected in pairs in series, which are connected in parallel in their entirety.
  • the size of the capacitance value is determined by the degree of coverage of the metal layers 3/5 or 4/5 and can therefore be made as small as desired.
  • the metal structuring on the foils 1 and 2 can be produced in a known manner, for example by passing the continuously metallized foils past the burn-out rollers, the structuring according to the invention being achieved in the desired manner by burning away the metal layers.

Abstract

L'invention concerne un condensateur électrique, en particulier un condensateur au plastique ou multicouche, comportant un montage en série intérieur. Ledit condensateur est constitué d'au moins deux feuilles de plastique (1, 2) qui sont pourvues de couches de métal (3, 4, 5). Les deux couches de métal (3, 4) se trouvant sur la première feuille de plastique (1) sont séparées l'une de l'autre par une bande (8) exempte de métal qui est recouverte de couches métalliques (5). Ces couches métalliques (5) présentent une section circulaire ou elliptique et définissent, par leur grandeur, la valeur de la capacité du condensateur.
