Title
(EN) EXTRACTOR OF A BUSHING CONDUCTOR FROM A BUSHING INSULATOR FOR A DEAD TANK CIRCUIT BREAKER
(FR) EXTRACTEUR DE CONDUCTEUR DE TRAVERSÉE D'UN ISOLATEUR DE TRAVERSÉE POUR DISJONCTEUR DE RÉSERVOIR HORS TENSION
Abstract
(EN) An extractor (7) for at least partially extracting a bushing central conductor from a bushing insulator. The extractor (7) comprises a supporting member (92, 96), a movable member (110) and lifting means. The supporting member (92, 96) is configured to be rigidly secured to the bushing insulator. The movable member (110) is configured to be rigidly secured to the bushing central conductor. The lifting means are configured to move the movable member (110) along the supporting member (92, 96).
(FR) L'invention concerne un extracteur (7) permettant d'extraire au moins partiellement un conducteur central de traversée d'un isolateur de traversée. L'extracteur (7) comprend un élément de support (92, 96), un élément mobile (110) et des moyens de levage. L'élément de support (92, 96) est conçu pour être solidement fixé à l'isolateur de traversée. L'élément mobile (110) est conçu pour être solidement fixé au conducteur central de traversée. Les moyens de levage sont configurés pour déplacer l'élément mobile (110) le long de l'élément de support (92, 96).
