Description
<Desc/Clms Page number 1>
Bi-Metallauslöser mit Shunt.
Als thermische Auslöser werden vielfach Bi-Metallstreifen angewandt, die sieh bei Erwärmung durch Stromdurehbiegen und dadurch eine mechanische oder elektrische Wirkung hervorrufen. Die Bi-MetalIstreifen können z. B. als Auslöseorgan bei Überstromschaltern Verwendung finden, wodurch eine verzögerte Abschaltung bei Überstrom erhalten wird. Zweckmässig werden die Bi-Metalle vom Hauptstrom durchflossen, weil dadurch eine stromabhängige, verzögerte Überstromauslösung erreicht wird.
Zur Bewältigung grosser Überstromstärken werden aber die vom Hauptstrom durchflossenen Bi-Metallauslöser verhältnismässig dick und breit, und es kommt noch die Gefahr des Durchschmelzens hinzu, da das Bi-Metall aus schlechten elektrischen Leitern besteht. Bisher hilft man sich dadurch, dass
EMI1.1
flossen werden.
Der Vorschlag der Erfindung geht nun dahin, die Bi-Metalle selbst leitfähiger zu machen, indem der Shunt in Gestalt von glltleitendem Metall galvanisch auf dem Bi-Metallstreifen niedergeschlagen wird. Man erhält dadurch für hohe Stromstärken einen billigen Bi-Metallauslöser von guter Elastizität und verhältnismässig geringer Dicke.

Bi-metal release with shunt.
Bi-metal strips are often used as thermal triggers, which when heated by current bending and thus cause a mechanical or electrical effect. The bi-metal strips can, for. B. can be used as a tripping device for overcurrent switches, whereby a delayed shutdown is obtained in the event of overcurrent. The bi-metals are expediently traversed by the main current, because this results in a current-dependent, delayed overcurrent release.
In order to cope with large overcurrent strengths, however, the bimetal triggers through which the main current flows are relatively thick and wide, and there is also the risk of melting through, since the bimetal consists of poor electrical conductors. So far you have helped yourself by
EMI1.1
will flow.
The proposal of the invention is now to make the bi-metals themselves more conductive by the shunt in the form of sliding metal is deposited galvanically on the bi-metal strip. This gives an inexpensive bimetal release with good elasticity and relatively small thickness for high currents.
