Patent

CA 2625108

In an earthing switch a release mechanism releases pressure stored in a puffer type arc cancelling chamber by releasing the chamber at a predetermined area toward a stationary contact unit during a full stroke extent of a movable contact unit so that the puffering operation can be deterred from execution.

Il s'agit d'un sectionneur de terre. Il comprend un mécanisme de libération qui libère la pression emmagasinée dans une chambre de suppression d'arc du type à soufflage. Pour ce faire, cette libération dans la chambre est effectuée à une zone prédéterminée vers une unité de contact fixe, lors de toute l'étendue de la frappe de l'unité de contact mobile. Ainsi, il est possible d'empêcher l'exécution du soufflage.
