Abstract

Ein induktives Element mit einer Messvorrichtung zum Bestimmen der magnetischen Flussdichte oder einer magnetischen Sättigung im induktiven Element weist einen Hauptkern (1) mit mindestens einer Hauptwicklung (2) zum Erzeugen eines Magnetfeldes im Hauptkern (1) auf. Dabei weist die Messvorrichtung einen vom Hauptkern (1) verschiedenen Messkern (3) mit einer Messwicklung (4) zum Erzeugen eines Magnetfeldes im Messkern (3) auf. Ein von der Hauptwicklung (2) erzeugter Hauptfluss und ein von der Messwicklung (4) erzeugter Messfluss überlagern sich in mindestens einem Teilbereich der beiden Kerne (1, 3). Die Messvorrichtung zur Messung der magnetischen Flussdichte im Hauptkern (1) weist eine Messeinheit (7) auf, welche dazu ausgebildet ist, die Messwicklung (4) zu speisen und Messsignale an der Messwicklung (4) zu erfassen und daraus einen Absolutwert der magnetischen Flussdichte des Hauptflusses zu bestimmen und/oder ein Signal zur Detektion einer Sättigung zu entnehmen.An inductive element with a measuring device for determining the magnetic flux density or a magnetic saturation in the inductive element has a main core (1) with at least one main winding (2) for generating a magnetic field in the main core (1). In this case, the measuring device has a measuring core (3) which is different from the main core (1) and has a measuring winding (4) for generating a magnetic field in the measuring core (3). A main flow generated by the main winding (2) and a measuring flow generated by the measuring winding (4) are superimposed in at least one subregion of the two cores (1, 3). The measuring device for measuring the magnetic flux density in the main core (1) has a measuring unit (7) which is designed to feed the measuring winding (4) and to detect measuring signals on the measuring winding (4) and from this an absolute value of the magnetic flux density of the Main flow to determine and / or to take a signal to detect a saturation.
