Title (EN) FIXING OF A MEDIUM- OR HIGH-VOLTAGE ELECTRICAL APPARATUS ON A BASE BY FORCE FITTING
(FR) FIXATION D'UN APPAREIL ELECTRIQUE DE MOYENNE OU HAUTE TENSION SUR UNE BASE PAR EMMANCHEMENT A FORCE
Abstract: front page image
(EN)The assembly system used makes it possible to obtain a general external surface of a wide part of a medium- or high-voltage circuit breaker, and which is perfectly smooth and has no protruding element. A gas guidance tube (20) is fixed to a base (10) by means of a snap fastening consisting mainly of two respective projections (13) and (23) that are required to be housed in respective grooves (12) and (24). The nominal diameters before mounting of the projections with respect to their corresponding grooves are very slightly greater so as to obtain a very tight fit by force fitting so as to obtain an assembly of maximum reliability. Application to medium- and high-voltage circuit breakers.
(FR)Le système d'assemblage utilisé permet d'obtenir une surface externe générale d'une partie large d'un disjoncteur de moyenne ou haute tension parfaitement lisse et sans élément protubérant. Un tube de guidage de gaz (20) est fixé à une base (10) au moyen d'un encliquetage constitué principalement de deux saillies respectives (13) et (23) devant se loger dans des rainures respectives (12) et (24). Les diamètres nominaux avant montage des saillies par rapport à leurs rainures correspondantes sont très légèrement supérieurs de manière à obtenir un ajustement très serré par emmanchement à force pour obtenir un assemblage de fiabilité maximale. Application aux disjoncteurs de moyenne et haute tension.
