Description
Elektrische Wicklung mit Temperaturkompensation Die Erfindung bezieht sich auf eine elektrische Wicklung mit Temperaturkompensation durch Vorschaltung eines thermo-negativen Widerstandes. Die Vorschaltung eines solchen Widerstandes ist bei einem Hubmagnet bekannt. Hier sollen die Temperaturänderungen in dem thermo-negativen Widerstand die Widerstandsänderungen der Erregerwicklung zur Verminderung der Temperaturabhängigkeit der Zugkraft ausgleichen.Electrical winding with temperature compensation The invention relates on an electrical winding with temperature compensation through an upstream connection a thermo-negative resistor. The upstream connection of such a resistor is known from a lifting magnet. Here the temperature changes are supposed to be in the thermo-negative Resistance the changes in resistance of the field winding to reduce the temperature dependence compensate for the pulling force.
Die Erfindung hat die Aufgabe, die thermische Zeitkonstante des thermo-negativen Widerstandes an die der elektrischen Wicklung anzupassen und damit eine bessere Kompensation zu erzielen. Erfindungsgemäß dient als Widerstand ein Heißleiter, mit dem zur Erhöhung der Wärmekapazität vorzugsweise auswechselbare Mengen von Stoffen mit gutem Wärmeleitvermögen in wärmeleitenden Kontakt gebracht werden.The invention has the task of reducing the thermal time constant of the thermo-negative Resistance to adapt to that of the electrical winding and thus a better one To achieve compensation. According to the invention, a thermistor is used as a resistor to increase the heat capacity, preferably exchangeable quantities of substances be brought into thermally conductive contact with good thermal conductivity.
Die Erfindung soll an Hand der Zeichnung näher erläutert werden. Sie zeigt eine Wicklung mit der bekannten Temperaturkompensation.The invention will be explained in more detail with reference to the drawing. she shows a winding with the known temperature compensation.
Der Wicklung 1 ist ein Heißleiter 2 vorgeschaltet. Parallel zu dem Heißleiter liegt ein ohmscher Widerstand 3. Die Widerstandszunahme der Wicklung bei Erwärmung wird durch die Widerstandsabnahme des sich ebenfalls erwärmenden Heißleiters kompensiert, und der Strom bleibt konstant. Da einerseits der Temperaturkoeffizient des Heißleiters um eine Größenordnung größer als der von Kupfer oder Aluminium ist und andererseits die Temperatur im Heißleiter ein Vielfaches von der der Wicklung beträgt, braucht der Widerstand des Heißleiters nur ein entsprechend kleiner Teil des Wicklungswiderstandes zu sein, um die Widerstandsänderung auszukompensieren. Die durch den Heißleiter vernichtete Energie beträgt daher nur etwa 10 °/o der Nutzenergie der Wicklung.A thermistor 2 is connected upstream of the winding 1. In parallel with that NTC thermistor is an ohmic resistance 3. The resistance increase of the winding when heated, the resistance of the thermistor, which also warms up, decreases compensated and the current remains constant. Since on the one hand the temperature coefficient of the thermistor is an order of magnitude larger than that of copper or aluminum and on the other hand the temperature in the thermistor is a multiple of that of the winding the resistance of the thermistor only needs a correspondingly small part of the winding resistance to compensate for the change in resistance. The energy destroyed by the thermistor is therefore only about 10% of the useful energy the winding.
Die thermische Zeitkonstante der Heißleiter ist im allgemeinen wesentlich kleiner als die der zu kompensierenden Wicklung. Um den dadurch bedingten thermischen Einschwingvorgang bei Kombination mit der Wicklung zu dämpfen und die thermische Zeitkonstante des Heißleiters in sehr weiten Grenzen zu vergrößern, werden Mengen von Stoffen mit gutem Wärmeleitvermögen, die vorzugsweise auswechselbar sind, mit dem Heißleiter in wärmeleitenden Kontakt gebracht. Der Heißleiter und die aufgebrachten zusätzlichen Stoffe werden thermisch gut isoliert.The thermal time constant of the thermistors is generally important smaller than that of the winding to be compensated. To the resulting thermal Damping the transient process when combined with the winding and the thermal Increasing the time constant of the NTC thermistor within very wide limits will require quantities of substances with good thermal conductivity, which are preferably interchangeable, with brought the thermistor into thermally conductive contact. The thermistor and the applied additional materials are thermally well insulated.
