Description

Gleichstromerregtes Relais für veränderliche Betätigungsspannung, insbesondere für Regelzwecke Bei gleichstromerregten Relais, insbesondere bei Relais für Regelzwecke, besteht vielfach die Aufgabe, daß sie auch bei veränderlicher Betätigungsspannung eine gleichbleibende Kraftwirkung besitzen. Um dies zu erreichen, hat man bereits vorgeschlagen, an dem Relaiseisenkern zwischen der Hauptwicklung und einer an die gleiche Spannung wie die Hauptwicklung angeschlossenen Zusatzwicklung, deren Magnetfluß dem der Hauptwicklung entgegengerichtet ist, einen magnetischen Nebenschluß vorzusehen, welcher sich mit zunehmender Spannung schneller sättigt als die übrigen Teile des Eisenweges. Bei diesem Relais hat es sich nun gezeigt, daß die Zusatzwicklung bei geringer Spannung, also bei einem Teil des Arbeitsbereiches, die Zugkraft des Hauptmagneten in unerwünschter Weise schwächt, daß also die Vorteile, die durch die. Anordnung der Zusatzwicklung erzielt werden, in der Hauptsache nur bei höheren Spannungen bestehen.DC-excited relay for variable actuation voltage, especially for control purposes with DC-excited relays, especially with relays for control purposes, there is often the task of ensuring that it can also be used with a variable actuation voltage have a constant force. To do this, one already has proposed to the relay iron core between the main winding and one to the same voltage as the main winding connected auxiliary winding, its magnetic flux which is opposite to the main winding, to provide a magnetic shunt, which saturates faster with increasing voltage than the other parts of the Iron way. In this relay it has now been shown that the additional winding at low voltage, i.e. for part of the working area, the pulling force of the main magnet undesirably weakens, so that the advantages created by the. arrangement the additional winding can be achieved, mainly only at higher voltages exist.

Um nun die nachteilige Wirkung der Zusatzwicklung in Fortfall zu bringen, schlägt die Erfindung vor, die Zusatzwicklung bei geringer Spannung ganz oder teilweise unwirksam zu machen, d. h. den die Zusatzwicklung durchfließenden Strom zu schwächen oder zu unterbrechen. Dies kann beispielsweise durch ein Relais geschehen, das bei geringer Spannung Widerstände in den Stromkreis der Zusatzwicklung einschaltet oder den Strom ganz unterbricht. Um die plötzliche Änderung der magnetischen Verhältnisse zu vermeiden, wie sie bei dem Schalten eines Relais auftreten, kann man die gewünschte Stromschwächung auch durch die Verwendung spannungsabhängiger Widerstände, z. B. durch Glimmlampen, welche in den Stromkreis der Zusatzwicklung eingeschaltet werden, erreichen.In order to eliminate the adverse effect of the additional winding, the invention proposes the additional winding at low voltage in whole or in part render ineffective, d. H. to weaken the current flowing through the auxiliary winding or interrupt. This can be done, for example, by a relay that is used at low voltage switches on resistors in the circuit of the additional winding or completely interrupts the electricity. The sudden change in magnetic conditions to avoid, as they occur when switching a relay, one can use the desired Current weakening also through the use of voltage-dependent resistors, e.g. B. by glow lamps, which are switched on in the circuit of the additional winding, reach.
