摘要:
A tripping device for switches (1) is equipped with a magnet yoke (16), an armature element (18) that works herewith to actuate a tripping shaft (14), and a lever element (23) that can be tilted about the axis (15) of the tripping shaft for adjusting the distance (L) between the magnet yoke and the armature element. This tripping device finds application in a switch contact arrangement with a plurality of switch contacts (1) arranged adjacent to one another wherein the lever element (23) consists of an adjusting shaft that extends parallel to the axis (15) of the tripping shaft (14) and on which are arranged a plurality of adjusting arms (24) corresponding to the number of switch contacts.
摘要:
A switching chamber housing is disclosed for a power switch with a double turning contact breaker. The switching chamber housing (1) is composed of two housing modules (2, 3) and an extinguishing chamber (19) is arranged in the area of the fixed contact pieces (6, 7) to extinguish the arcs which are formed between the contact pieces of the double turning contact breaker. In order to obtain a switching chamber housing (1) which is easy and economical to produce, with extinguishing chambers (19) which have a reproducible extinguishing behaviour once the switching chamber is assembled, the two housing modules (2, 3) are substantially L-shaped parts whose inner marginal surfaces (4, 5) face each other. The first parts (17, 18) of the housing, which correspond to the first branches of the L-shaped housing modules (2, 3), are designed as extinguishing chambers (19). Also disclosed are the housing modules (2, 3) used to produce such a switching chamber housing.
摘要:
Une chambre d'extinction d'arc pour appareil électrique, notamment un disjoncteur ou un bloc limiteur de courant comporte un boîtier (12) quasi étanche en matériau isolant gazogène pour le logement de contacts séparables (14,16,18) à répulsion électrodynamique. Le contact mobile (18), en forme de pont épouse sensiblement la configuration interne du boîtier (12) en jouant le rôle d'un piston disposé de part et d'autre d'un premier compartiment (32) générateur de pression sous l'action de l'arc, et un deuxième compartiment (34) communiquant avec le premier à travers un jeu J minimal. La pression dans le deuxième compartiment (34) est inférieure à celle règnant dans le premier compartiment. Des circuits magnétiques (42,44) peuvent être agencés pour accélérer le contact mobile (18) vers la position d'ouverture.
摘要:
Combiné sectionneur-interrupteur comprenant au moins un élément de contact fixe de coupure (7), un élément de contact fixe de sectionnement (8) et au moins un équipage mobile (1) comportant un élément de contact mobile de coupure (4) électriquement relié à un élément de contact mobile de sectionnement (5). La disposition des éléments de contact mobiles (4, 5) par rapport aux éléments de contact fixes (7, 8) est conçue de telle manière que lors de la fermeture du combiné, le contact fixe de sectionnement soit fermé avant que ne s'établisse le contact électrique entre l'élément fixe de coupure (7) et l'élément de contact mobile de coupure (4) et, inversement, l'ouverture du contact de coupure soit réalisée avant que ne se produise l'ouverture du contact de sectionnement.
摘要:
A switch assembly includes first and second contact members which are operatively provided to take one of two positions, a break-position in which the first and second contact members are separated from each other, and a make-position in which the first and second contact members are electrically connected with each other. Magnetic members are provided operatively in association with the first and second contact members to define a closed magnetic loop with a current path extending through the loop, when the first and second contact members are turned to the make-position. The magnetic members attract each other by the magnetic flux through the closed loop to maintain the first and second contacts in the make-position when the current flowing through the current path is not zero. Thus, the first and second contact members are permitted to return to the break-position at a zero crossing point of a.c. current flowing through the contacts.
摘要:
An electric switch comprising a frame (2), a first stationary contact (41) stationarily fixed to the frame (2), a contact support element (6) adapted to move relative to the frame (2) between a first position and second position, a movable contact (8) stationarily fixed relative to the contact support element (6) and having a longitudinal direction, a first arc shutter (91), and an actuation system for moving and guiding the first arc shutter (91) during an opening event. The actuation system comprises a first actuator member (711) stationarily fixed relative to the frame (2), and a second actuator member (721) stationarily fixed relative to the first arc shutter (91). The first arc shutter (91) is adapted to move in an outward direction during the opening event, wherein the outward direction is parallel to the longitudinal direction of the movable contact (8).
摘要:
A low passive intermodulation (PIM) RF rotary switch comprises a plurality of center conductors connected to stationary pads, at least two rotatable pads connected by a rotatable pad bridge. Depending on the switching state at least two stationary pads are in close proximity to at least two rotatable pads, thus generating a RF signal connection between the center conductors via the stationary and rotatable pads.
