Definitions

  • the invention relates to a switch lock for multi-pole electrical switching devices, such as circuit breakers and disconnectors, according to the preamble of the independent claims.
  • the key switch consists of a U-shaped drive lever with its outer legs tiltably mounted in fixed side panels and an operating handle, a toggle mechanism with an upper toggle lever, a lower toggle lever and a spring mechanism, and a support lever which is pivoted between the side panels ,
  • the toggle levers are articulated to one another via a toggle lever axis.
  • the spring-loaded mechanism engages between the toggle axis and the drive lever.
  • the lower toggle is articulated to a selector shaft.
  • the switching shaft carries movable contact arrangements with one-armed movable contacts which can be pivoted against the action of contact pressure springs within the so-called stroke.
  • the support lever is articulated to the upper toggle lever.
  • the switching lock can be reset by bringing the support lever beyond its off position into a supporting connection under the action of the spring force accumulator by transferring the drive lever to a latching mechanism that is operatively connected to the release means.

  • the latching mechanism is omitted on the one hand and the support lever is fixed on the other hand.
  • the disadvantage here is that additional components are required to fix the support lever. Presentation of the invention
  • the invention is therefore based on the object of being able to carry out a conversion from a switch lock with triggering into a switch lock without triggering without additional parts.
  • the solution is that one and the same physical axis performing a certain function in a triggerable switch lock in a first position serves for fixing the support lever in a second position that is not capable of triggering in a trigger lock that is different from the first position.
  • the proposed solution eliminates the previous need to use additional parts when installing a trigger lock that is not capable of triggering, which is used in particular for a disconnector.
  • Another axle positioned in the side panels fixes the support lever in a second position between the side panels.
  • the displaceable axis is expediently used as a bearing axis within the latching mechanism, as a stop axis relative to the support lever or as a distance axis designed for the side panels.

Abstract

L'invention concerne un verrou de connexion destiné à des appareils de commutation électriques multipolaires tels que des disjoncteurs et des sectionneurs. Un axe exerçant une première fonction dans une première position d'un verrou de connexion déclenchable sert à fixer le levier d'appui sur un verrou de connexion non déclenchable dans une deuxième position différente de la première. Ainsi, un premier axe (42) du verrou de connexion déclenchable (72a) est disposé dans une première position entre les branches extérieures (18). Par ailleurs, le mouvement de pivotement du levier d'entraînement (28) est limité par rapport au levier d'appui (58) libéré par le mécanisme d'encliquetage (54). Sur le verrou de connexion non déclenchable (72b), le premier axe (42) est en revanche disposé dans une deuxième position entre les panneaux latéraux (19) et relié mécaniquement au levier d'appui (58).
