Description

Die Erfindung bezieht sich' auf Reglerrel'ais od. dgl., z. B. auf Relais zur Spannungsregelung von Kleinanlagen. Solche Relais haben die Auf- gabe, den Stromerzeuger bei Überschreiten des-Sollwertes der Anlagenspannung' 'entsprechend .herabzuregeln und bei Unterschreiten des Wertes hinaufzuregeln. Es ist meist notwendig, daß die Spannungsgrienzen, bei denen die Reglerrelais ansprechen, ein für allemal eindeutig festliegen. Sie sollen auch nicht durch Schwankungen der Raumtemperatur oder der Temperatur des Reglers selbst verlagert werden. Bei bekannten Temperaturkompensationsvorrichtungen für Relais, die beispielsweise mit sog. Heißleitern arbeiten, muß wegen der Ungleichmäßigkeit der Heißleiter jedes Relais individuell abgeglichen werden. Oft streuen die Heißleiter in ihren Eigenschaften so stark,. daß eine solche Abgleichung kaum durchführbar ist.The invention relates to 'on regulator relay or the like. B. on relays for voltage regulation of small systems. Such relays have the up display, '.herabzuregeln the generator when exceeding the target value of the system voltage' corresponding hinaufzuregeln and when falling below the value. It is usually necessary that the voltage limits at which the controller relays respond are clearly defined once and for all. Nor should they be shifted by fluctuations in room temperature or the temperature of the controller itself. In known temperature compensation devices for relays, which work with so-called thermistors, for example, each relay must be adjusted individually because of the unevenness of the thermistors. Often the thermistors vary so widely in their properties. that such a comparison is hardly feasible.

Die Erfindung hat die Aufgabe,' eine' für die Massenfertigung vorteilhafte einfache und möglichßt betriebssichere Temperaturkompensation, zu. schaffen, bei der eine individuelle Abgleichung nicht erforderlich ist. Erfindungsgemäß hat das Reglerrelais od. dgl. außer einer mit einem nicht oder wenig temperaturabhängigenVorwiderstanditiRei#e liegenden Haup#erregerwicklung noch eine mit temperaturabhängigemVorwiderstandinReihe liegende Gegenerregerwicklung solcher Abgleichung, daß die resultierenden Amperewindungen der-beiden Wicklungen im Arbeitsbereich von Raumtemperaturschwankungen praktisch unabhängig sind.The invention has the object of providing "a" temperature compensation which is advantageous for mass production, which is simple and reliable in operation . that do not require individual adjustment. According to the invention, the controller relay or the like has, in addition to a main exciter winding with a temperature-dependent series resistor, with a non-temperature-dependent series resistor or a counter-exciter winding in series such that the resulting ampere turns of the two windings are practically independent of room temperature fluctuations in the operating range.

Die Erfindung wird an Hand des in der Zeichnung dargestellten Ausführungsbeispiels erläutert. An den Kleminm 1; 2 liegt die zu regelnde Spannung. Das Spannungsreglerreläis, 'däs beispielsweise einen Widerstand im Erregerkreis ehlüs Generators st&uürt;' -hat#* -eine :Haupterregerwicklung 3 und #iiie (iege'n'w'-icklun'9-4. Der Haupt'-erregerwicklung 3 istein prakfischvonTemperatur# schwankungen unabhängiger - Widerstand: 5;, # der Gegenwicklung 4 ein Widerstand 6 aus Kupfer od. dgl. vorgeschaltet.The invention is explained using the exemplary embodiment shown in the drawing. To the Kleminm 1; 2 is the voltage to be regulated. The voltage regulator relay, 'that, for example, disturbs a resistor in the excitation circuit ehlüs the generator' -has # * -eine: main excitation winding 3 and #iiie (iege'n'w'-icklun'9-4. The main'-excitation winding 3 is practically independent of temperature # fluctuations - resistance: 5 ;, # of the reverse winding 4 a resistance 6 made of copper or the like.

Bei Temperatursteigerung würde, wenn das Reglerrelais nur die Wicklung 3- hätte, infolge Zunahme des Widerstandes der Wicklung der Erregerstrom zurückgehen. Dadurch würden sich die Ansprechgrenzen in das Gebiet höherer Spannungen verlagern. Dadurch, daß der Erregerwicklung ä clieWicklung 4 entgegenwirkt und wegen der Temperaturabhängigkeit des Widerstandes 6 der Strom in der Wicklung 4 mit Temperaturzunahme stärker prozentual abnimmt als der der Wicklung 3, kann man es leicht dahin bringen, daß die resultierendenAmperewindungen praktisch von Schwankungen der Raumtemperatur unabhängig sind. Hat die Reglereinrichtung mehrere Reglerrelais, dann kann der Vorwiderstand 6 durch die Gegenerregerwicklungen' der übrigen Relais ersetzt werden, so daß also jedes Relais einen Haupterregerkreis, aber alle Relais zusammen einen gemeinsamen Gegenerregerkreis haben.With an increase in temperature, if the controller relay only had winding 3 , the excitation current would decrease due to an increase in the resistance of the winding. This would shift the response limits to the area of higher voltages. Characterized in that the excitation winding ä clieWicklung 4 counteracts and the current in the coil 4 decreases more as a percentage for the temperature dependence of the resistor 6 with increase in temperature than that of the winding 3, it can be easily bring meaning that the resultierendenAmperewindungen are practically independent of fluctuations of the room temperature . If the control device has several control relays, then the series resistor 6 can be replaced by the opposing excitation windings of the remaining relays, so that each relay has a main excitation circuit, but all relays together have a common opposing excitation circuit.

Die Erfindung bietet den Vorteil, daß sich in der Serienfertigung ohne individuelle Einregelung leicht eine Temperaturabhängigkeit der Relais erzielen-läßt, ohne daß dazu besondere Mittel, wie Heißleiter, Wärmelegierungen od. dgl., erforderlich sind.The invention offers the advantage that it can be used in series production A temperature dependency of the relay can easily be achieved without individual adjustment, without the need for special means such as thermistors, heat alloys or the like are.
