Description

Hydraulischer Regler, insbesondere zur Regelung elektrischer Größen Die Erfindung bezieht sich auf elektrische Regler; ihr liegt die Aufgabe zugrunde, die Fehler zu vermeiden, die durch Widerstandsänderung einer Meßspule infolge von Temperaturänderungen entstehen, und bezieht sich insbesondere auf elektrische Spannungsregler, bei denen eine Flüssigkeit, z. S. Öl, zur Steuerung des Regelorgans verwendet wird.Hydraulic regulator, in particular for regulating electrical quantities The invention relates to electrical regulators; it is based on the task to avoid the errors caused by the change in resistance of a measuring coil as a result of Temperature changes arise, and relates in particular to electrical voltage regulators, where a liquid, e.g. S. Oil, is used to control the regulating device.

Man hat bereits vorgeschlagen, eine Spule mit gleichbleibendem, von der Temperatur unabhängigem Widerstand dadurch zu schaffen, daß man sowohl Leitermaterial mit positivem als auch mit negativem Temperaturkoeffizienten benutzte. Bei den bisherigen `.'ersuchen, eine Temperaturl>omp--nsati-)n durch Einschaltung von Materialien mit entgegengesetzten Temperaturkoeffizienten zu erreichen, hat man bisher einen wesentlichen Gesichtspunkt außer acht gelassen. Man hat nicht beachtet, an welcher Stelle die betreffenden kompensierenden Materialien eingeschaltet wurden; man berücksichtigte die Materialien wohl in der Schaltung, aber nicht bezüglich der Art, in der diese Materialien und der zu kompensierende Teil erwärmt wurden. So wurde vorgeschlagen, zur Kompensation des Temperaturkoeffizienten einer Spule einen Vorschaltwiderstand zu verwenden, der an ganz anderer Stelle angebracht war, so daß keine Gewähr dafür bestand, daß bei einer Erhöhung der Temperatur der Spule gleichzeitig auch die Temperatur dieses Vorschaltwiderstandes erhöht würde. Da von einem derartigen Vorschaltwiderstand jeweils, während er für Regulierzwecke benutzt wird, ein veränderlicher Teil eingeschaltet ist, ist auch au"s diesem Grunde der Einfiuß der Kompensationswirkung eines derartigen Widerstandes auf die zu kompensierende Spule un einheitlich.It has already been proposed to use a coil with a constant, of to create resistance independent of temperature by using both conductor material used with both positive and negative temperature coefficients. With the previous ones `. 'seek a temperature l> omp - nsati-) n by including materials with To achieve opposite temperature coefficients, one has up to now an essential one Point of view disregarded. No one paid attention to where the relevant compensating materials have been switched on; one considered the materials probably in the circuit, but not in terms of the way in which they are Materials and the part to be compensated have been heated. So it was proposed a series resistor to compensate for the temperature coefficient of a coil to use, which was attached in a completely different place, so that no guarantee for it insisted that if the temperature of the coil increased, the temperature would also increase at the same time this ballast resistance would be increased. Because of such a series resistor while it is being used for regulating purposes, a variable part is switched on is, for this reason, too, is the in fl uence of the compensatory effect of such Resistance to the coil to be compensated uneven.

Erfindungsgemäß wird der Widerstand mit negativem Temperaturkoeffizienten in dem Flüssigkeitsstrom des Reglers gelagert. Auf diese Weise wird erreicht, daß stets dieselbe Temperaturbeziehung zwischen der zu kompensierenden Spule und dem kompensierenden Widerstand besteht, eine Temperaturbeziehung, die lediglich von der Außentemperatur abhängt, also von einer einzigen Größe, so daß die Kompensation so gewählt werden kann, daß gerade die Schwankungen dieser Größe kompensiert werden.According to the invention, the resistor has a negative temperature coefficient stored in the liquid flow of the regulator. In this way it is achieved that always the same temperature relationship between the coil to be compensated and the compensating resistance exists, a temperature relationship that is merely of the outside temperature depends, so on a single variable, so that the compensation can be chosen so that precisely the fluctuations of this size are compensated.

Dies wird besonders vorteilhaft dadurch erreicht, daß man den Kompensationswiderstand mit der zu kompensierenden Meßspule in Reihe schaltet, wobei man nach dem weiteren Gegenstand der Erfindung einen solchen Kompensationswiderstand verwendet, der nicht irgendwelchen Nebenzwecken, wie Verstellung zwecks Regulierung, dient, da durch Nebenaufgaben das Temperaturgleichgewicht zwischen der Spule urid dem Kompensationswiderstand eine Störung erleiden würde.This is achieved particularly advantageously in that the compensation resistor connected in series with the measuring coil to be compensated, whereby one after the other The invention uses such a compensation resistor that does not any secondary purposes, such as adjustment for the purpose of regulation, serves as a result Side tasks the temperature equilibrium between the coil urid the compensation resistor would suffer a disturbance.

Wenn auch beim Betrieb des Reglers jeder einzelne stromdurchflossene Widerstand Temperaturschwankungen erfährt, wenn ferner die Druckflüssigkeit zum Betriebe eines hydraulischen Reglers Temperaturschwankungen erfährt, so besteht bei einer erfindungsgemäßen Ausbildung des Reglers trotzdem die Gewähr, daß der Druckflüssigkeitsstromeinen Temperaturausgleich zwischen der Spule und dem kompensierenden Widerstand hembieiführt, so daß auf diese Weise die- Kompensationswirkung wirklich erst erzielt werden kann.Even if every single current-carrying one is in operation of the controller Resistance experiences temperature fluctuations, if furthermore the hydraulic fluid to the Operation of a hydraulic controller experiences temperature fluctuations, so there is in a design of the controller according to the invention, the guarantee that the Pressure fluid flow a temperature compensation between the coil and the compensating Resistance hembie leads, so that in this way the compensation effect really can only be achieved.

Als geeignetes Material für den Widerstand mit negativem Temperaturkoeffizienten kann z. B. Kohle verwendet werden.As a suitable material for the resistor with a negative temperature coefficient can e.g. B. coal can be used.

Damit der in Reihe geschaltete Widerstand mit negativem Temperaturkoeffizienten tatsächlich den Temperatureinfluß zu beseitigen imstande ist, wird im Gegensatz zu bekannten Anordnungen die Einrichtung so getroffen, daß der Widerstand mit negativem Temperaturkoeffizienten ständig der Meßspule vorgeschaltet ist, solange diese überhaupt eingeschaltet ist, und daß er ausgeschaltet wird, sobald die Meßspule ausgeschaltet wird.So that the resistor connected in series with a negative temperature coefficient is actually able to eliminate the influence of temperature is in contrast to known arrangements made the device so that the resistance with negative Temperature coefficient is constantly connected upstream of the measuring coil, as long as it is at all is switched on, and that it is switched off as soon as the measuring coil is switched off will.
