A capacitor element (20) for a power capacitor with a dielectric film layer (3) and an electrode layer arranged on each flat side of the film layer, which electrode layers are divided into at least three metallized areas (4, 9, 10), separated from each other, in order to form an inner series connection arranged to conduct a load current, of which three areas at least one is divided into segments (5) separated by non-metallized sections (6), and at least one bridge (7) arranged to electrically connect two of the segments together. In accordance with the invention the bridge is so arranged that, in the area divided into segments, the load current appears substantially only in the segments. The invention also relates to a power capacitor with such a capacitor element and also a metallized tape for such a power capacitor. Image

L'invention concerne un élément de condensateur (20) pour un condensateur de puissance doté d'une membrane diélectrique (3) et d'une couche d'électrodes disposées sur chaque côté plan de la membrane, les couches d'électrodes étant divisées en au moins trois zones métallisées (4, 9, 10), séparées les unes des autres, de manière à former un montage en série intérieur disposé de façon à conduire un courant de charge, parmi les trois zones au moins une d'elle est divisée en segments (5) séparés par des sections non métallisées (6), et au moins un pont (7) est disposé de manière à connecter électriquement deux segments. Selon l'invention, le pont est disposé de manière que, dans la zone divisée en segments, le courant de charge apparaisse presqu'uniquement dans les segments. L'invention concerne également un condensateur de puissance doté d'un tel élément de condensateur ainsi que d'une bande métallisée pour un tel condensateur.
