Definitions

  • Fuse strips or disconnectors are usually equipped with fuses. However, more and more frequently, especially for feed-in systems, devices are used that are not equipped with fuses but with separating knives. This is particularly true in terms of lower power loss and short-circuit protection on the primary side of the feed-in transformer. Here, a dynamic short-circuit strength is often expected from the switching device. It is understood that in case of short circuit, the bar deliberately unresponsive.

    le dispositif de blocage (23) empêche le couteau de sectionnement (4) de quitter l'agencement des contacts (2, 3) par projection en cas de court-circuit et présente un élément (24) pour transférer une force de blocage, en cas de court-circuit, directement de l'agencement des contacts (2, 3) au couteau de sectionnement (4), caractérisé en ce que l'élément (24) est mobile essentiellement dans un plan perpendiculaire à l'axe longitudinal (39) du couteau de sectionnement (4).
  2. Dispositif selon la revendication 1, caractérisé en ce que l'élément (24) est à même de pivoter.
  3. Dispositif selon la revendication 1 ou 2, caractérisé en ce que l'élément peut être actionné d'une manière protégée contre les contacts accidentels, via une pièce de manoeuvre (36).
  4. Dispositif selon l'une quelconque des revendications 1 à 3, caractérisé en ce que l'élément (24) est constitué d'un matériau à résistance mécanique élevée, en particulier de fil métallique.
  5. Dispositif selon l'une quelconque des revendications 1 à 4, caractérisé en ce que l'élément (24) vient enserrer le couteau de sectionnement (4) par l'arrière, du côté se détournant d'un contact (3) de l'agencement des contacts (2, 3), et/ou l'élément (24) vient enserrer le contact (3) par l'arrière, du côté se détournant du couteau de sectionnement (4), ou bien vient s'insérer dans le contact en question.
  6. Dispositif selon la revendication 5, caractérisé en ce que l'élément (24) présente un premier tronçon (25, 27, 37), qui est disposé essentiellement dans le plan perpendiculairement à l'axe longitudinal du couteau de sectionnement (4), ainsi qu'un deuxième tronçon (28), qui est disposé essentiellement perpendiculairement au premier tronçon (25, 27, 37) et essentiellement parallèlement à l'axe longitudinal du couteau de sectionnement (4), et le premier tronçon (25, 27, 37) vient enserrer le couteau de sectionnement (4) par l'arrière et le deuxième tronçon (28) vient enserrer un contact (3) de l'agencement des contacts (2, 3) par l'arrière.
  7. Dispositif selon la revendication 5 ou 6, caractérisé en ce que l'élément (24) est inséré dans au moins une ouverture (21) du contact (3), qui est délimitée par une traverse (18) sur le côté tourné vers le couteau de sectionnement (4).
  8. Dispositif selon l'une quelconque des revendications 5 à 7, caractérisé en ce que l'élément (24) est réalisé en étant replié en U (25) dans la zone de son extrémité se détournant du contact (3), à des fins de coopération de la branche libre (37) du U (25) avec le couteau de sectionnement (couteau 20).
  9. Dispositif selon l'une quelconque des revendications 1 à 8, caractérisé en ce que l'élément (24) est guidé en pivotement dans un élément stationnaire faisant office de boîtier ou dans une plaque de recouvrement stationnaire (30).
  10. Dispositif selon la revendication 9, caractérisé en ce que l'élément (24) est à même de s'encliqueter dans deux positions (positions d'encliquetage 32, 33) dans l'élément faisant office de boîtier, respectivement dans la plaque de recouvrement (30).
  11. Dispositif selon l'une quelconque des revendications 3 à 10, caractérisé en ce que la pièce de manoeuvre (36) est montée dans un couvercle (6) pour le recouvrement du couteau (1), en particulier est montée en mobilité, et la pièce de manoeuvre (36) coopère avec l'élément ou avec un recouvrement (35) en forme de capuchon, relié à l'élément (24).
