Description

Mit magnetfeldabhängigen Elementen, wie Feldplatten, Hallgeneratoren, Magnetdioden und dargleichen ausgerüstetes Strommeßglied Erfindung bezieht sich auf ein mit magnetfeldabhängigen Elementen, Feldplatten, Hallogeneratoren, Magnetdioden und dergleichen ausgeetes Strommeßglied zur Strommessung in einer Stromschiene. With magnetic field-dependent elements such as field plates, Hall generators, Magnetic diodes and similarly equipped current measuring element invention relates on one with magnetic field-dependent elements, field plates, hello generators, magnetic diodes and the like current measuring element for measuring current in a busbar.

st bekannt, magnetfeldabhängige Elemente zu verwenden, um eine Meß-Se zu erzeugen, die hinsichtlich ihrer Größe und eventuellen Polariin fasten, gesetzmäßigen Seziehungen zu einem Strom steht, der einen netfluß Ennerhalb eines magnetischen Meßkreises bewirkt. Sofern der ichstrom, dessen Größe gemessen werden soll, durch Umformung aus einem hstromg@tz beispielsweise über Transformatoren in Verbindung mit Sechssen-Gleichrichtern erzeugt wird, besitzt dieser Gleichstrom einen erlichen Sechselstromanteil bzw. eine Welligkeit, die sich störend auf Meßgenauigkeit des Strommeßgliedes auswirkt. Es ist bekannt, diese igkeit durch Anordnung von Siebgliedern zu unterdrücken. Diese Methode aber nicht nur aufwending, sondern beeiflußt auch die Größe des Meßdes infolge des Raumbedarfs für die Siebglieder. st known to use magnetic field dependent elements to measure a Se to produce that fast, lawful with regard to their size and eventual polarity There is a connection to a current that has a net flux within a magnetic one Measuring circle causes. Provided that the ichstrom, the size of which is to be measured, goes through Conversion from a hstromg @ tz, for example via transformers in connection is generated with six rectifiers, this direct current has a substantial AC component or a ripple that interferes with the measurement accuracy of the Current measuring element affects. It is known that this igkeit through the arrangement of sieve members to suppress. This method is not only expensive, but also influential the size of the measurement as a result of the space required for the sieve members.

Enf@@@@@ liegt die Aufgabe zugrunde, ein in seinem Aufbau einfaches @@@@@@@nzugeben, welches es ermöglicht, den Wechselstromanteil des den Magnetfluß erzeugenden Gleichstromes ohne zusätzlichen Raumbedarf zu unterdrücken. The underlying task of Enf @@@@@ is to create a simple structure @@@@@@@ which enables the alternating current component of to suppress the direct current generating magnetic flux without requiring additional space.

Die Erfindung löst diese Aufgabe dadurch, daß ein Magnetjoch angewer wird, durch welches die zu messende Stromachiene hindurchgeführt ist und daß das Magnetjoch mit der durch dieses hindurchgeführten Seromschiene und den im Luftspalt befindlichen magnetfeldabhängigen leni ten durch eine Kurzenchlußwicklung derart gedämpft wird, daß das Magn feld, welches die magnetfeldabhängigen Elements durchsetzt, ric-' den Augenblickswerten des Stromflusses in der Stromachiinen folgen In der Zeichnung ist ein Ausführungsbeispiel der Anordnung nach de Erfindung dargestellt0 mit 1 ist die den zu messenden Strom führunde Stromschiene Oszeichle welche vorzugsweise aus Kupfer besteht und durch das Magnetjoch 2 hi durchgeführt ist. Teil 3 stellt ein bzw. mehrere im Luftspalt des Magnetjochs angeordnete mangetfeldabhängige Widerstände, vorzugsweise F platten oder Hallgeneratoren dar. Mit 4 ist eine Kurzschlußwindung b ein Kurzschlußring bezeichnet, welcher vorzugsweise aus Kupfer besteThe invention solves this problem in that a magnet yoke is used through which the Stromachiene to be measured is passed and that the Magnetic yoke with the seroma rail passed through it and the one in the air gap located magnetic field-dependent leni th through a short-circuit winding in such a way is damped that the Magn field, which penetrates the magnetic field-dependent element, ric- 'follow the instantaneous values of the current flow in the Stromachiinen The drawing shows an embodiment of the arrangement according to the invention with 1 is the current to be measured leading conductor Oszeichle which preferably consists of copper and is passed through the magnet yoke 2 hi. Part 3 represents one or more magnetic field-dependent resistors arranged in the air gap of the magnet yoke, preferably F plates or Hall generators. With 4 is a short-circuit turn b denotes a short-circuit ring, which is preferably made of copper
