Description

Bi-Metallauslöser mit Shunt Als thermische Auslöser werden vielfach Bi-Metallstreifen verwendet, die sich bei Erwärmung durch Strom durchbiegen und dadurch eine mechanische oder elektrische Wirkung hervorrufen. Die Bi-Metallstreifen können beispielsweise als Auslöseorgan bei überstromschaltern Verwendung finden, wodurch eine verzögerte Abschaltung bei Überstrom erhalten wird. Zweckmäßig werden die Bi-Metallstreifen vom Hauptstrom durchflossen, weil dadurch eine stromabhängige verzögerte überstromauslösung erreicht wird.Bi-metal releases with shunt As thermal releases are often Bi-metal strips used, which bend when heated by electricity and thereby cause a mechanical or electrical effect. The bi-metal strips can be used, for example, as a tripping device for overcurrent switches, whereby a delayed shutdown is obtained in the event of overcurrent. Become useful the bi-metal strips flowed through by the main stream, because it is a current-dependent one delayed overcurrent release is achieved.

Zur Bewältigung großer Überstromstärken werden die vom Hauptstrom durchflossenen Bi-Metallstreifen verhältnismäßig dick und breit. Außerdem besteht noch die Gefahr des Durchschmelzens, da das Bi-Metall aus schlechten elektrischen Leitern besteht. In solchen Fällen werden vielfach parallel zu den Bi - Metallstreifen Nebenwiderstände (Shunts) geschaltet, so daß die Bi-Metallstreifen nur noch von: einem Teilstrom durchflossen werden.In order to cope with large excess currents, the are from the main current traversed bi-metal strips relatively thick and wide. In addition, there is nor the risk of melting through, since the bi-metal is made from bad electrical Ladders. In such cases, they are often parallel to the bi-metal strips Shunt resistors are switched so that the bi-metal strips only come from: flow through a partial stream.

Der Vorschlag der Erfindung geht nun dahin, das Bi-Metall selbst leitfähiger zu machen, indem das Shunt galvanisch auf dem Bi-Metallstreifen niedergeschlagen wird. Es wird dadurch der große Vorteil erzielt, daß der Auslöser bedeutend einfacher und kleiner und vor allen Dingen billiger wird als alle bekannten Ausführungen.The proposal of the invention is now to make the bi-metal itself more conductive to make by electroplating the shunt on the bi-metal strip will. This has the great advantage that the shutter release is much easier and becomes smaller and, above all, cheaper than all known designs.
