Die Erfindung betrifft eine Schaltung zur Stabilisierung des Stromes des wechselstromerregten Elektromagneten eines Betatrons oder Synchrotrons, bei der zwischen der Wicklung des Elektromagneten und der Speisespannungsquelle mindestens eine lineare Impedanz angeordnet ist, und die Strom-Spannungs-Charakteristik der Magnetwicklung nichtlinear ist.The invention relates to a circuit for stabilizing the current of the alternating current excited electromagnet a betatron or synchrotron, in which between the winding of the electromagnet and the supply voltage source is arranged at least one linear impedance, and the current-voltage characteristic the magnet winding is non-linear.
Die Magneten eines Betatrons oder Synchrotrons werden in der Regel von einem Strom mit Netzfrequenz gespeist, der entweder direkt oder über einen Transformator dem Netz entnommen wird. Der induktive Blindstrom, den die Betatron- oder Synchrotronmagneten dem Netz entnehmen, pflegt beträchtlich zu sein und wird in bekannten Schaltungen üblicherweise durch eine mit dem Magneten in Parallel- oder Serienresonanz bezüglich der Netzfrequenz verbundene Kondensatorbatterie kompensiert, so daß dem Netz lediglich der Wirkstrom zum Ausgleich der Verluste entnommen wird.The magnets of a betatron or synchrotron are usually powered by a current with mains frequency which is taken from the network either directly or via a transformer. The inductive reactive current that the betatron or synchrotron magnets draw from the network is maintained to be considerable and is in known circuits usually by one with the magnet capacitor bank connected in parallel or series resonance with respect to the mains frequency compensated, so that only the active current is taken from the network to compensate for the losses.
Bei einer sparsamen Ausführung des Magneten mit möglichst großer Eisensättigung wird die Charakteristik des Magneten nichtlinear; dies bedeutet, daß die Impedanz nicht mehr unabhängig vom durchfließenden Strom ist und demgemäß sich mit der angelegten Netzspannung ändert. Eine Schwankung der Netzspannung bewirkt dann auf Grund dieser nichtlinearen Charakteristik eine Verstimmung des Resonanzkreises, so daß ein erheblicher Blindstrom zu fließen beginnt, der die Speisevorrichtungen oder auch die Magnetwicklung überlasten kann.With an economical design of the magnet with the greatest possible iron saturation, the characteristic of the magnet non-linear; this means that the impedance is no longer independent of the flowing through Current and accordingly changes with the applied mains voltage. A fluctuation in the Mains voltage then causes a detuning of the resonance circuit due to this non-linear characteristic, so that a considerable reactive current begins to flow, which the feed devices or can also overload the magnet winding.
Um diese Gefahr zu vermeiden, werden bei bekannten Schaltungen die Netzspannungsschwankungen dadurch abgeschwächt, daß der Magnet aus dem Netz über einen Regeltransformator gespeist wird, mit welchem das die Vorrichtung bedienende Personal eine konstante Spannung am Magneten einregelt. Eine andere Möglichkeit besteht darin, die Kapazität der Kondensatorbatterie nachzuregeln und damit den Resonanzkreis nachzustimmen.In order to avoid this risk, the mains voltage fluctuations are used in known circuits weakened by the fact that the magnet is fed from the mains via a regulating transformer with which the personnel operating the device regulates a constant voltage on the magnet. Another possibility is to readjust the capacity of the capacitor bank and so to re-tune the resonance circuit.
Nachteilig bei diesen bekannten Vorrichtungen und Verfahren ist eine erhebliche Verkomplizierung der Vorrichtung durch die Regelelemente sowie der durch die notwendigen Eingriffe des Bedienungspersonals schwerfällige Betrieb.A disadvantage of these known devices and methods is a considerable complication of the Device by the control elements as well as by the necessary interventions by the operating personnel cumbersome operation.
Die Verwendung bekannter ferromagnetischer Stabilisatoren, bei denen die stabilisierte Spannung von einer mit einer linearen Induktivität in Reihe liegenden nichtlinearen Induktivität, der eine Kapazität parallel liegt, abgenommen wird, würde bei der Anwendung zur Stabilisierung des Magnetstroms eines Betratrons oder Synchrotrons Vorrichtungen von großem Ausmaß erfordern. Außerdem ergeben Schaltung zur Stabilisierung des Stromes des wechselstromerregten Elektromagneten eines Betatrons oder SynchrotronsThe use of known ferromagnetic stabilizers, in which the stabilized voltage of a non-linear inductance in series with a linear inductance, which is a capacitance parallel is removed, would be used to stabilize the magnetic current of an Betratron or Synchrotron require large scale devices. Also surrendered Circuit for stabilizing the current of the alternating current excited electromagnet of a Betatrons or Synchrotrons

Die erwähnten Nachteile werden durch die Erfindung mittels einer Schaltung der eingangs genannten Art in überraschender Weise dadurch gelöst, daß entweder die durch die Magnetwicklung gebildete nichtlineare Impedanz in Reihe mit mindestens einer linearen Kapazität an die Quelle der Speisespannung geschaltet ist, wobei parallel zu der aus nichtlinearer Impedanz und linearer Kapazität gebildeten Serienschaltung eine lineare Induktivität geschaltet ist, oder daß die nichtlineare Impedanz in Reihe mit mindestens einer linearen Induktivität an die Quelle der Speisespannung geschaltet ist, wobei parallel zur nichtlinearen Impedanz eine lineare Kapazität geschaltet ist, derart, daß durch die Parallelschaltung der linearen Induktivität bzw. der linearen Kapazität eine gegenüber der Wirkung der übrigen Impedanzen entgegengesetzte Phasendrehung bewirkt wird und der Blindstrom der Serienschaltung der linearen und nichtlinearen Impedanzen kompensiert wird.The disadvantages mentioned are alleviated by the invention by means of a circuit of the type mentioned at the beginning Art solved in a surprising manner in that either the one formed by the magnet winding non-linear impedance in series with at least one linear capacitance at the source of the supply voltage is connected, in parallel with the series circuit formed from non-linear impedance and linear capacitance a linear inductance is connected, or that the nonlinear impedance is in series with at least a linear inductance is connected to the source of the supply voltage, being parallel to the non-linear impedance a linear capacitance is connected in such a way that through the parallel connection the linear inductance or the linear capacitance compared to the effect of the other impedances opposite phase rotation is caused and the reactive current of the series connection of the linear and non-linear impedances is compensated.
Diese erfindungsgemäße Schaltungsanordnung stabilisiert den Magnetstrom in engen Grenzen, erfordert keinerlei Bedienung und vergrößert weder die Ausmaße noch die Kosten der Vorrichtung.This circuit arrangement according to the invention stabilizes the magnet current within narrow limits, which is required no operation and neither increases the size nor the cost of the device.
