Description
Die Erfindung betrifft eine stromkompensierte Funk entstördrossel mit einem weichmagnetischen Kern zur Einschaltung in die Einspeiseleitungen eines Gerätes der LeistungselektronikThe invention relates to a current-compensated radio Suppressor choke with a soft magnetic core Activation in the feed lines of a device from Power electronics
Eine stromkompensierte Funkentstördrossel ist beispiels weise in DE-A 35 26 047 beschrieben. Die Wicklungen dieser Drossel sind so geschaltet, daß sich die magnetischen Flüsse, die aufgrund des Betriebsstromes induziert werden, gegenseitig aufheben, während Störströme, die gleichphasig durch beide Wicklungen fließen, eine Magnetisierung des weichmagnetischen Kerns zur Folge haben. Hierdurch wirkt die somit entstandene stromkompensierte Funkentstördrossel als sehr kleiner induktiver Widerstand in Bezug auf die Betriebsströme, während Störströme, die beispielsweise von angeschlossenen Geräten ausgehen und sich über Erde schließen, auf eine sehr hohe Induktivität treffen.A current-compensated radio interference suppression choke is an example as described in DE-A 35 26 047. The windings of this Chokes are switched so that the magnetic Rivers induced by the operating current cancel each other out while interference currents are in phase flow through both windings, a magnetization of the result in soft magnetic core. This works the resulting current-compensated radio interference suppression choke as a very small inductive resistor in relation to the Operating currents, while interference currents, for example, from connected devices go out and down over earth close, encounter a very high inductance.
Der Kern der bekannten stromkompensierten Funkentstör drossel ist beispielsweise aus einem amorphen Band gewickelt. Hierdurch erreicht man eine sehr hohe Permea bilität, die es gestattet, bei kleinem Bauvolumen der Funkentstördrossel eine hohe Dämpfungswirkung zu erzielen. Dies liegt vor allem daran, daß die Induktivität der Drossel neben Windungszahl und Kernquerschnitt im wesent lichen von der relativen Permeabilität des weichmagneti schen Materials des Magnetkerns abhängt. The core of the well-known current-compensated radio interference suppression throttle is made of an amorphous band, for example wrapped. This gives a very high permeate bility, which allows the small size of the Interference suppressor to achieve a high damping effect. This is mainly because the inductance of the Mainly choke in addition to number of turns and core cross-section Lichen from the relative permeability of the soft magnetic depends on the material of the magnetic core.
Setzt man derartige stromkompensierte Funkentstördrosseln ein für Verbraucher, die über gesteuerte Gleich- und Wechselrichter oder eine entsprechende gesteuerte Leistungselektronik an das Netz angeschlossen sind, so stellt man - insbesondere bei langen Leitungen zwischen Leistungselektronik und Verbraucher - fest, daß beim Erproben verschiedener Drosseln mit unterschiedlicher Bewicklung, Kerngröße und Kernmaterial eine Erhöhung der Permeabilität des eingesetzten Kernmaterials in manchen Fällen zu einer deutlichen Verschlechterung der Entstörwirkung führt.If you set such current-compensated radio interference suppression chokes one for consumers who have controlled equality and Inverters or a corresponding controlled Power electronics are connected to the network, so you put between - especially with long lines Power electronics and consumers - firmly that at Testing different chokes with different ones Wrapping, core size and core material increase the Permeability of the core material used in some Cases to a significant deterioration of the Interference suppresses.
Um diesen Effekt zu vermeiden, kann man auf Kernmaterial mit niedriger Permeabilität zurückgreifen. Dies hat aller dings zur Folge, daß man zur Einhaltung einer bestimmten Mindestinduktivität entweder die Windungszahl erhöhen und/oder den Kernquerschnitt vergrößern muß, so daß zur Gewährleistung der Entstörwirkung für derartige, über eine Leistungselektronik gesteuerte oder geregelte Verbraucher wesentlich größere und teurere Entstördrosseln erforderlich werden.To avoid this effect, one can use core material with low permeability. Everyone has this the consequence that one has to adhere to a certain Minimum inductance either increase the number of turns and / or the core cross section must enlarge, so that for Guarantee of interference suppression for such, via a Power electronics controlled or regulated consumers much larger and more expensive suppressor chokes required will.
Aufgabe der vorliegenden Erfindung ist es nun, eine Funkentstördrossel anzugeben, die auch bei derartigen Verbrauchern eine gute Entstörwirkung hat, ohne daß besonders große Abmessungen, bedingt durch Erhöhung von Windungszahl und/oder Kernquerschnitt erforderlich werden.The object of the present invention is now a Radio interference suppression indicate that also in such Has a good interference suppression effect without particularly large dimensions, due to the increase of Number of turns and / or core cross section may be required.
Die Lösung dieser Aufgabe besteht erfindungsgemäß in der Wahl eines Kernwerkstoffes für den weichmagnetischen Kern einer stromkompensierten Drossel mit den Merkmalen, wie sie im Kennzeichen des Patentanspruchs 1 aufgeführt sind. Besonders vorteilhaft ist es, wenn der Kernwerkstoff aus bestimmten, in den Unteransprüchen angegebenen Legierungen besteht und wenn die magnetische Kennlinie dieses Werk stoffes durch die dort genannten Maßnahmen entsprechend eingestellt ist. The solution to this problem consists in the Choice of a core material for the soft magnetic core a current-compensated choke with the features as they are listed in the characterizing part of claim 1. It is particularly advantageous if the core material is made of certain alloys specified in the subclaims exists and if the magnetic characteristic of this work accordingly by the measures mentioned there is set.
Nanokristalline Legierungen, die zum Einsatz als Kern werkstoff für eine erfindungsgemäße Funkentstördrossel vorteilhafterweise eingesetzt werden können, werden so hergestellt, daß man zunächst eine Legierung mit der Formel:Nanocrystalline alloys that are used as a core Material for a radio interference suppression choke according to the invention can be used advantageously, so manufactured that you first an alloy with the Formula:
Fe100-a-b-c-x-y-zCuaRbMcSixByXz Fe 100-abcxyz Cu a R b M c Si x B y X z
herstellt,
wobei mit
R = eines oder mehrere der Elemente Nb, Ta, Mo, Zr und/oder
anderer Übergangsmetalle der Nebengruppen IVb, Vb und VIb
bezeichnet ist,
M = Co und/oder Ni bedeutet und mit
X = C, Ge und/oder andere Elemente der Hauptgruppen IIIa
IVa Va bezeichnet ist. In der Formel gelten für die
prozentualen Anteile der Elemente in at%:
a = 0-2; b = 2-10; c = 0-20; x = 0-18; y = 2-14;
z = 0-5 und 7 < b+x+y+z < 30. Diese Legierung wird in
einem Tiegel verflüssigt. Aus dem Tiegel wird die Legierung
auf eine sich drehende Kühltrommel aufgebracht, wo sie zu
einem amorphen Band erstarrt. Dieses amorphe Band ist
duktil und kann leicht zu Ringbandkernen gewickelt werden.
Die nanokristalline Struktur im Kernwerkstoff wird dann
durch eine Wärmebehandlung eingestellt, die abhängig von
der Kristallisationstemperatur des Werkstoffes ist und
mindestens 5 min bis max. etwa 8 h dauern kann. Je nach
Kristallisationstemperatur der betreffenden angewendeten
Legierung findet die Wärmebehandlung in einem Temperatur
bereich von 470 bis 680°C statt. Um die angestrebten
relativen Permeabilitätswerte zwischen 10 000 und 60 000 zu
erreichen, wird mindestens während eines Teils der Wärme
behandlungszeit ein magnetisches Feld angelegt.manufactures,
being with
R = one or more of the elements Nb, Ta, Mo, Zr and / or other transition metals of the subgroups IVb, Vb and VIb is designated,
M = Co and / or Ni and with
X = C, Ge and / or other elements of the main groups IIIa IVa Va. In the formula, the following applies to the percentage of elements in at%:
a = 0-2; b = 2-10; c = 0-20; x = 0-18; y = 2-14; z = 0-5 and 7 <b + x + y + z <30. This alloy is liquefied in a crucible. The alloy is applied from the crucible to a rotating cooling drum, where it solidifies into an amorphous band. This amorphous band is ductile and can be easily wound into ring band cores. The nanocrystalline structure in the core material is then set by a heat treatment, which is dependent on the crystallization temperature of the material and at least 5 minutes to max. can take about 8 hours. Depending on the crystallization temperature of the alloy used, the heat treatment takes place in a temperature range from 470 to 680 ° C. In order to achieve the desired relative permeability values between 10,000 and 60,000, a magnetic field is applied for at least part of the heat treatment time.
Zur Verminderung der Permeabilität wird das Feld dann so angelegt, daß es als Querfeld wirkt, also die Magneti sierungsrichtung des angelegten Feldes quer zur späteren Magnetisierungsrichtung des gewickelten Ringbandkerns verläuft. Die beschriebenen nanokristallinen Legierungen haben einen relativ hohen spezifischen elektrischen Widerstand R < 90 µΩcm. Dadurch werden die durch Störströme entstehenden Wirbelstromverluste im Kern begrenzt und damit auch im Hinblick auf die Erwärmung relativ kleine Baugrößen einsetzbar.The field then becomes so to reduce permeability created that it acts as a transverse field, i.e. the magneti direction of the created field across to the later Magnetization direction of the wound toroid runs. The described nanocrystalline alloys have a relatively high specific electrical Resistance R <90 µΩcm. This will cause interference currents resulting eddy current losses are limited in the core and thus also relatively small sizes in terms of heating applicable.
Durch Teilluftspalte, unterschiedliche Behandlung von Teilen des Ringbandkerns oder ähnliche Maßnahmen kann man mit besonderem Vorteil erreichen, daß sich eine magnetische Kennlinie für den weichmagnetischen Kern ergibt, die bei kleiner Vormagnetisierung zunächst eine hohe relative Permeabilität im Bereich von 20 000 bis 60 000 aufweist, die dann bis zum Erreichen der Sättigung bei höherer Vormagnetisierung um mindestens 30% bezogen auf den Ausgangswert abfällt, so daß diese Permeabilität sich auf einen Wert zwischen 10 000 und 40 000 einstellt.Through partial air gaps, different treatment of Parts of the toroidal core or similar measures can be taken achieve with particular advantage that a magnetic Characteristic curve for the soft magnetic core results in small bias first a high relative Has permeability in the range from 20,000 to 60,000, which then until saturation is reached at higher Premagnetization by at least 30% based on the Initial value drops, so that this permeability increases sets a value between 10,000 and 40,000.
