Definitions

  • This Invention relates to the control of an electrical arc as occurs for example In an electric switch when the switch 1s opened.
  • An electrical arc is a plasma produced by a current flowing in a gaseous conductor such as ionised air. Such a current flow can interact with a magnetic field and be diverted to bring about extinction.
  • the plasma can be cooled and the ionisation reduced by being directed into thermally and/or electrically conductive elements.
  • a blast of air or other gas can also be used to "blow-out" the arc.
  • a method of controlling an electrical arc occurring between separating electrical contacts, at least one contact having a respective current flow conductor including positioning adjacent said contacts conductive arc accepting elements diverging from adjacent said contacts, positioning said at least one conductor outwardly of said contacts and around said diverging elements, causing or permitting said arc to occur at said contactsas arc segments for entry between said diverging elements, and causing said segments to move along said elements by electromagnetic action with arc current flow 1n said at least one conductor for self-extinguishing extension by said divergence.
  • the arc length is increased much more rapidly in a switch according the present invention than in the prior art.
  • the arc in the present invention can be substantially the whole of the periphery of the contact zone and is preferably as complete a circle as possible, subject to constructional needs.

Abstract

Un interrupteur de courant électrique comprend une zone de contact et une zone d'extinction d'arc entourant la zone de contact. La zone de contact comprend au moins deux contacts séparables pour fournir une pluralité d'intervalles de coupure autour de la zone de contact, la zone d'extinction d'arc comportant des éléments d'extinction d'arc espacés autour de la zone de contact et s'étendant depuis celle-ci vers l'extérieur. Les éléments d'extinction d'arc espacés coopèrent avec les intervalles de contact pour recevoir des arcs qui se forment sur les intervalles de contact dès la séparation des contacts en vue de l'interruption du courant traversant les contacts fermés. Un conducteur de l'interrupteur peut s'étendre sur au moins une partie de la périphérie de la zone d'extinction d'arc.
