Patent

CA 2454556

The invention relates to an overvoltage arrester comprising a central electrode (1) and at least one outer electrode (2), in which an electrically conductive spring band (3) is attached to the central electrode (1), and a spring force (F) is exerted onto the outer electrode (2). According to the invention, an electrical component (4) is placed between the spring band (3) and the outer electrode (2). Said component is non-conductive during the occurrence of the trigger voltage of the overvoltage arrester and generates heat during current conduction. The spring band (3) rests against an electrically conductive contact element (5), which is attached to a spacer element (7) by means of a meltable material (6) and located at distance from the outer electrode (2). When the material (6) is melted, the contact element (5) is pressed against the outer electrode (2) by the spring band (3). The triggering mechanism is advantageous in that it reacts quickly thereby reducing the formation of sparks and thus the fire hazard.

L'invention concerne un coupe-circuit de surtension comportant une électrode centrale (1) et au moins une électrode périphérique (2). Ce coupe-circuit comprend un étrier de ressort (3) électriquement conducteur, qui est fixé sur l'électrode centrale (1) et exerce une tension (F) sur l'électrode périphérique (2). Entre l'étrier de ressort (3) et l'électrode périphérique (2) se trouve un élément électrique (4) qui n'est pas conducteur lors d'une tension d'amorçage du coupe-circuit de surtension et qui génère de la chaleur lors de la conduction de courant. L'étrier de ressort (3) appuie contre un élément de contact (5) électriquement conducteur, lequel est fixé à un élément d'écartement (7) au moyen d'une masse (6) fusible, à une certaine distance de l'électrode périphérique (2), l'élément de contact (5) étant poussé par l'étrier de ressort (3) contre l'électrode périphérique (2) lorsque la masse (6) est fondue. Le mécanisme de déclenchement présente l'avantage de réagir très rapidement, diminuant ainsi le risque de formation d'étincelles et d'incendie.
