 auftretende   Selbstinduktionsstrom schliesst sich   über die zur Erregerwicklung parallel liegende Wicklung g und   durchfliesst   dieselbe im umgekehrten Sinn als der vorher in dieser fliessende Strom, so dass die Magnetisierung des Kernes c wirksam geschwächt und der bewegliche Kontaktteil e durch die Feder rasch in die   Schliessstellung   zurückgezogen wird. Der Ohmsche Widerstand der Wicklung g kann dabei so klein gehalten werden, dass eine vorzügliche   Funkendämpfung   erzielt wird, ohne gleichzeitig die Betriebssicherheit der Regelvorrichtung zu beeinträchtigen.

 The self-induction current that occurs closes over the winding g, which is parallel to the excitation winding, and flows through it in the opposite direction than the current flowing in it before, so that the magnetization of the core c is effectively weakened and the movable contact part e is quickly pulled back into the closed position by the spring. The ohmic resistance of the winding g can be kept so small that excellent spark attenuation is achieved without impairing the operational reliability of the control device at the same time.

Claims

PATENT CLAIM: Voltage regulator for electrical power generators, in which the excitation circuit itself is alternately opened and closed by a vibration contact, characterized in that an inductive resistor is combined with the excitation winding of the power generator in a direct parallel connection to form a permanently closed circuit and as a winding on the core of the electromagnet of the Vibration controller is arranged that the current flowing in the inductive resistor when the vibration contact is opened acts in a demagnetizing sense on the core, for the purpose of a. to achieve effective damping of the opening spark and increase the vibration speed of the controller. which eliminates the need for special devices to prevent fluctuations in light, EMI2.1
