Description
Elektrothermischer Schalter Bei elektrothermischen Schalbern, welche mit Bimetall arbeiten, hat es sich #I als wichtig gezeigt, die Bewegung des Binietallstreifens unter Vermittlung von Federn auf die Kontaktstelle zu übertragen. Nun haben aber die Bimetallstreifen die Eigenart, daß ihre Bewegung nicht mit der Erwärmung ver-' hältnisgleich -verläuft. Andererseits ist es wünschenswert, das Arbeiten des Kontaktes den jeweils vorliegenden Anforderungen anzupassen, d. h. daß man z. B. bei höheren Spannungen und kleineren Stromstärken einen großen Schaltweg wünscht, wobei man auch mit einem kleineren Kontaktdruck auskommt, während man umgekehrt hei geringen Spannungen und größeren' Stromstärken einen höheren Kontaktdruck auf Kosten des Schaltweges anstrebt.Electrothermal switch For electrothermal scarfs, which When working with bimetal, it has been shown to be important, the movement of the bimetal strip to be transferred to the contact point with the help of springs. Well have but the bimetallic strips have the peculiarity that their movement does not proportionally -progresses. On the other hand, it is desirable to have working contact adapt to the respective requirements, d. H. that one z. B. at higher Voltages and smaller currents a large switching path desires, whereby one A smaller contact pressure can also be used, while conversely it is called low Voltages and larger currents result in higher contact pressure at the expense of the Aiming for switching travel.
Gegenstand der Erfindung ist nun ein Thermoschalter, dessen Fortschritt den bisherigen gegenüber darin besteht, daß zur Verbesserung sowohl des erstmaligen Einsteilens wie auch des späteren Arbeitens in obengenannter Richtung zwischen dem Bimetallstreifen und dem beweglichen Kontaktträger ein oder zwei Zwischenfedern angeordnet sind. In der Zeichnung ist ein Ausführungsbeispiel dargestellt, und zwar zeigt Abb. i die für kleineren Schaltweg und größeren Kontaktdruck und. Abb. z die für größeren Schaltweg und kleineren Kontaktdruck bevorzugte Anordnung.The invention now relates to a thermal switch, its progress compared to the previous is that to improve both the first Set up as well as the later work in the above-mentioned direction between the Bimetal strips and the movable contact carrier one or two intermediate springs are arranged. In the drawing, an embodiment is shown, namely Fig. i shows the for smaller switching travel and larger contact pressure and. Fig.z the Preferred arrangement for longer switching travel and lower contact pressure.
Beide Anordnungen sind Grenzfälle; durch Verwendung beider Federn und durch passende Wahl ihrer Abmessungen lassen sich alle Zwischenfälle erreichen.Both arrangements are borderline cases; by using both springs and by choosing their dimensions appropriately, all incidents can be achieved.
In beiden Abbildungen sind i der Bimetallstreifen, 2 der bewegliche Kontaktträger., 3 und q. die Zwischenfedern bzw. die Zwischenfeder.In both figures i is the bimetallic strip, 2 the movable one Contact carrier., 3 and q. the intermediate springs or the intermediate spring.
