Title (EN) BUSHING FOR AN ELECTRICAL APPARATUS IN A METAL CASING AND ASSEMBLY FOR A GROUND ISOLATOR WITH IMPROVED MECHANICAL RETENTION
(FR) TRAVERSEE POUR APPAREILLAGE ELECTRIQUE SOUS ENVELOPPE METALLIQUE ET ENSEMBLE POUR SECTIONNEUR DE MISE À LA TERRE A MAINTIEN MECANIQUE AMELIORE
Abstract: front page image
(EN)Assembly for a ground isolator comprising a fixed contact (18) fixedly mounted in a bore (16) of a cap (6.2), the fixed contact (18) having a body of longitudinal axis (Y), a first longitudinal portion of which projects from the support and is connected to ground, the connection region between the first and second portions having a radial projection (26) comprising a first annular face (26.1) and a second annular face (26.2) that are inclined in relation to the longitudinal axis (Y). Electrical insulating means, for example in the form of two sleeves (38, 40), are mounted in the bore (16). The internal surface (42, 44) of the sleeves (38, 40) is shaped so as to bear flat against the first (26.1) and second (26.2) inclined faces, respectively, of the radial projection (26). A clamping plate (50) mounted on the cap (6.2) keeps the fixed contact (18) immobilized in the bore (16) via the sleeves (38, 40).
(FR)Ensemble pour sectionneur de mise à la terre comportant un contact fixe (18) monté fixe dans un alésage (16) d'un capot (6.2), le contact fixe (18) comportant un corps d'axe longitudinal (Y) dont une première portion longitudinale fait saillie du support et est raccordée à la terre, la zone de raccordement entre la première et la deuxième portion comportant un saillie radiale (26) comportant une première (26.1) et une deuxième (26.2) face annulaire inclinées par rapport à l'axe longitudinal (Y). Des moyens isolants électriques, par exemple sous la forme de deux manchons (38, 40), sont montés dans l'alésage (16). La surface intérieure (42, 44) des manchons (38, 40) est conformée pour venir en appui plan respectivement contre la première (26.1) et la deuxième (26.2) face inclinée de la saillie radiale (26). Une plaque de serrage (50) montée sur le capot (6.2) maintient immobile le contact fixe (18) dans l'alésage (16) via les manchons (38, 40).
