Abstract

L'invention concerne un mécanisme de déclenchement destiné à être utilisé dans un dispositif de protection contre les surtensions et le dispositif de protection contre les surtensions comprenant le mécanisme de déclenchement. Le mécanisme de déclenchement (100) comprend un support de cadre (110) destiné à être utilisé dans le maintien d'au moins un rhéostat à oxyde métallique (200), une tige de déclenchement (120) agencée de manière pivotante sur le support de cadre et connectée à une électrode (210) du rhéostat à oxyde métallique par l'intermédiaire d'une soudure à basse température, et un bloc pouvant coulisser (120) agencé de manière coulissante sur le cadre de support entre une première position et une seconde position et pressé de manière sollicitée vers une position de déclenchement. Dans un état de fonctionnement normal, le bloc pouvant coulisser est maintenu à la première position par la tige de déclenchement bloquant la pression de sollicitation. Dans un état déclenché, le bloc pouvant coulisser coulisse vers la seconde position sous l'effet de la pression de sollicitation, amenant la tige de déclenchement à pivoter le long de la direction à distance de l'électrode du rhéostat à oxyde métallique. En raison du fait que le mécanisme de déclenchement pivote à distance de l'électrode du rhéostat à oxyde métallique lorsqu'il est dans l'état déclenché, la distance électrique entre la tige de déclenchement et l'électrode est ainsi accrue, et la fiabilité de l'isolation électrique entre les deux est ainsi améliorée.
