PROCEDE DE REGLAGE DE LA COURSE D'ECRASEMENT DES CONTACTS ELECTRIQUES D'UN BLOC DE COUPURE, BLOC POUR LA MISE EN OEUVRE DUDIT PROCEDE ET DISPOSITIF DE COMMUTATION COMPORTANT UN TEL BLOC.

摘要

The invention concerns a method for adjusting the compression course of electrical contacts (32, 33) in a unitary cut-off block (80). On the inside, the unitary cut-off block comprises a casing (31), a fixed contact (32) and a movable contact (33) mounted slidingly on a movable contact-holder (38), the contact-holder being connected to an attachment head (51). The method comprises the following steps: placing the movable contact-holder (38) such that the movable contact (33) is in contact with the fixed contact (32); positioning an adjustment jig (600) between a reference surface of the casing (31) and a bearing surface of the attachment head (51); and adjusting a length of a transmission pin (52) connecting the attachment head (51) to the movable contact-holder (38).
