摘要:
Die Erfindung betrifft einen Schalter (1), insbesondere Lasttrennschalter, mit Anschlusselementen (3, 5), die über einen Schaltkontakt (12) verbindbar sind, dessen bewegliche Kontaktfläche (27) an einem beweglichen Kontaktelement (7) ausgebildet ist, die in der Schließstellung an der feststehenden Kontaktfläche (27, 28) anliegt. Um einen Aufbau mit besseren Positionsgenauigkeiten zu erzielen, wird vorgeschlagen, dass die beiden Anschlusselemente (3, 5) und das bewegliche Kontaktelement (7) jeweils eine ebene Flachseite (21, 22, 25) aufweisen und alle Flachseiten (21, 22, 25) in einer gemeinsamen Ebene (E) liegen, wobei die Anschlusselemente (3, 5) auf der einen Seite der gemeinsamen Ebene (E) und das bewegliche Kontaktelement (7) auf der anderen Seite angeordnet sind, dass eine Teilfläche der Flachseite (22) des einen Anschlusselements (5) die feststehende Kontaktfläche (28) bildet, dass eine Teilfläche der Flachseite (21) des anderen Anschlusselements (3) eine ebene Lagerfläche bildet, und dass das bewegliche Kontaktelement (7) mit seiner Flachseite (25) beweglich an der Lagerfläche anliegt.
摘要:
The invention relates to a medium voltage switchgear with an assembled pole part with integrated three-position switch, with pole part frames made of insulating material, between which a vacuum-interrupter is mounted, wherein the vacuum interrupter is provided with a fixed contact and a moving contact, so that one end of the frame is provided with a first support in order to fix the vacuum interrupter at the moving contact side, and fixation means for the fixed contact side at the other end of the frame. In order to to implement high technical functionality during reduction of the number of separate parts at same time, and additionally to implement a lower transmission resistance into the interconnection, the electrical connection between the movable part of the vacuum interrupter and the movable part of the two- or three-position switch is a mechanically flexible conductor element, and that the insulating pole part frames are provided with guiding means for the linear movable contact part of the two- or three- position switch, which are integrated into the pole part frames or the pole part frame arrangement.

La présente invention concerne un dispositif anti-rebond destiné à contrôler le rebond d'au moins un contact mobile (1,2,3) dans un appareil de protection électrique, ledit contact mobile étant apte à être déplacé entre une position dite de fermeture dans laquelle ledit contact mobile est en contact électrique avec un contact fixe (4,5,6) de l'appareil de manière à permettre le passage du courant entre ces deux contacts, et une seconde position dans laquelle ces deux contacts sont séparés, ledit dispositif comportant des moyens d'amortissement aptes à limiter le rebond du contact mobile à la fin de la manoeuvre de fermeture du contact mobile. Ce dispositif est caractérisé en ce qu'il comporte un ressort (13) monté sur l'un (1,2,3), dit premier, des deux contacts et apte à coopérer avec l'autre (4,5,6), dit second, de ces deux contacts, à la fin de la manoeuvre de fermeture, de manière à assurer l'amortissement du déplacement du contact mobile et l'indexation du contact mobile par rapport au contact fixe.

The invention relates to a conductor (2) for an electric apparatus that comprises a first electrically conductive bearing element (14) with a longitudinal axis and at least two electric contact elements (16.1, 16.2) to be brought into contact, the bearing element (14) having an recessed cylindrical shape with, on the outer periphery thereof, at least two housings (20, 21) for receiving said contact elements (16.1, 16.2), said housings (20, 21) being substantially symmetrically arranged, wherein the contact elements (16.1, 16.2) are retained in the housings (20, 21) by clamping. The conductor may form a mobile contact for a circuit-breaker.

Un dispositif inverseur de phase (100) est présenté dans lequel le nombre de pièces est minimisé. L'inversion est réalisée par des pinces de serrage (105) raccordées aux entrées et sorties du dispositif inverseur (100) et placées autour d'éléments (115) sur lesquels alternent les plages isolantes et conductrices (160). L'élément rotatif (150) comprend des plages de raccordement conductrices (160) pouvant être enserrées par les pinces (105) et reliées deux à deux par des circuits conducteurs. Lors de la rotation, les circuits conducteurs relient entre elles différentes pinces (105), c'est-à-dire des phases d'entrée et sortie différentes. Alternativement, les pinces de serrage (205) sont placées sur des barreaux (220) rotatifs par rapport à un support isolant comprenant des plages conductrices qui sont reliées aux bornes.
摘要:
A fixed contact (20) includes a pair of conduction members (31) that are arranged opposedly and in parallel to each other such that tip ends of the conduction members are oriented toward an opening, a support frame (pedestal member) (33) that tiltably supports bases of the conduction members, a leaf spring (pressurizing member) (43) that biases the conduction members (31) in a direction in which the tip ends of the conduction members approach each other, and an outer frame (shielding member) (45) that covers peripheries of the conduction members (31) and the leaf spring (43) and shields them from an outside electric filed, the leaf spring (43) is arranged on an outer side of the opposed conduction members (31), and the outer frame (45) is engages with the tip end of the conduction member (31), thereby maintaining an opening width between the tip ends of the conduction members (31) at a predetermined width.

A Medium Voltage line switch contact arrangement 1 comprising a fixed contact 2 and a movable contact assembly 3 operatively connectable to said fixed contact 2; the movable contact assembly 3 comprising a first 31 and a second 32 substantially flat blades parallel to each other, pivotally mounted on a support and rotationally connectable to said fixed contact 2; the fixed contact 2 comprises a contact element having a substantially flat body 20 with a first 21 and a second 22 contact surfaces delimited by a base 23 connected to a contact holder 24 and by a first 25, a second 26, a third 27 and a fourth 28 segments. The first segment 25 is substantially perpendicular to the third segment 27, with the first 25 and second 26 segments facing said movable contact assembly 3; the second segment 26 connects said first segment 25 to said third segment 26 and is inclined toward said fourth segment 28 so that the length 1 of the third segment 27 is shorter than the width L of said substantially flat body 20 as measured in correspondence of the connection point between said first 25 and second 26 segment.
