Charges inductives
Lors de la commutation d’électrovannes et d'autres charges inductives, des arcs avec des pics de tension allant jusqu'à plusieurs milliers de volts peuvent se produire. Il sont générés, pendant la commutation, par l'énergie accumulée dans la bobine et peuvent détruire le contact par l'évaporation et la migration du matériau. Un arc intense se produit lors de la commutation des charges inductives DC. Par conséquent, les contacts de relais sont soumis à une contrainte élevée et s'usent rapidement. L'utilisation de relais d'alimentation peut supprimer de manière fiable l'apparition de tels arcs. En outre, un circuit d'atténuation externe est recommandée. Les arcs se produisent également lors de la commutation des charges inductives AC, mais ils s'éteignent généralement automatiquement au passage par zéro suivant du courant de charge. Plus les charges inductives commutées sont grandes, plus les arcs qui se produisent sont forts. Dans les applications avec des charges inductives supérieures à 2 A, il convient donc d'utiliser des relais de puissance à la place des relais de signaux classiques. Sinon, il faut s'attendre à une réduction importante de la durée de vie des contacts. Dans les pages qui suivent, vous trouverez des produits spéciaux pour les charges inductives de commutation au-dessus de 2 A.
