Description
Anordnung zur Verringerung der Funkstörspannung eines Syrichrongenerators mit Uhyristorabsetzregler Die Erfindung bezieht sich auf eine Anordnung zur Verringerung der Funkstörspamlung eines über Gleichrichter erregten Synchrongenerators mit einem von einem Thyristorabsetzregler beeinflußten Absetzwiderstandskreis.Arrangement for reducing the radio interference voltage of a Syrichron generator with uhyristor reduction regulator The invention relates to an arrangement for reducing the radio interference signal of a synchronous generator excited by a rectifier with a withdrawal resistor circuit influenced by a thyristor withdrawal regulator.
Es ist bei Thyristorstromkreisen zur Funkentstörung bekannt, dem Thyristor einen LC-Tiefpass oder eine Reiheninduktivität zuzuordnen, wobei die Forderung erfüllt werden muß, daß sie für den Betriebsstrom bemessen sein muß, den Betrieb nicht nachteilig beeinflussen darf und im Betrieb im sättigungsfreien Bereich arbeiten muß, damit der Frequenzbereich für die Funkentstörung ausreichend groß bleibt. Außerdem muß die Eigenresonanz eier solchen Induktivität möglichst hoch sein, damit sie nicht als Kapazität wirken kann, was bei Frequenzen oberhalb der Eigenresonanzfrequenz der Fall ist. Diese Bedingungen können nur mit aufwendigen, großen einlagigen Stabkerndrosseln erfüllt werden.It is known for radio interference suppression in thyristor circuits, the thyristor to assign an LC low-pass or a series inductance, the requirement being met must be that it must be dimensioned for the operating current, the operation is not disadvantageous may influence and must work in the saturation-free range during operation so that the frequency range for radio interference suppression remains sufficiently large. Also must the natural resonance of such an inductance should be as high as possible so that it does not can act as a capacitance, which at frequencies above the natural resonance frequency the case is. These conditions can only be met with complex, large, single-layer rod core chokes to be fulfilled.
Der Erfindung liegt die Erkenntnis zugrunde, daß die absetzgeregelten Synchrongeneratoren einer solch aufwendigen Drosselausführung zur Funkentstörurlg nicht bedürfen.The invention is based on the knowledge that the withdrawal-regulated Synchronous generators of such a complex throttle design for radio interference suppression not need.
gemäß der Erfindung wird auf besonders einfache Weise bei absetzgeregelten Synchrongeneratoren der genannten Art eine Funkentstörung dadurch erreicht, daß im Absetzwiderstandskreis an Stelle des Absetzw.ideI.standes je eine gleiche, aus um einen isolierten Blechkern gewickelten Widerstandsdraht bestehende eigenschwingungsfreie Drossel vor und hinter dem Thyristor eingefügt ist.according to the invention is in a particularly simple manner in the case of settling controlled Synchronous generators of the type mentioned achieve radio interference suppression in that In the dropping resistance circuit, instead of the dropping point, there was an identical one each around an isolated Sheet metal core wound resistance wire existing Self-oscillation-free choke is inserted in front of and behind the thyristor.
Durch die symmetrische Anordnung der beiden Drosseln zum Thyristor wird eine besonders gute Unterdrückung von Störspannungen und auch eine Schonung des Thyristors erreicht.Due to the symmetrical arrangement of the two chokes to the thyristor becomes a particularly good suppression of interference voltages and also a protection of the thyristor reached.
Die Drosseln unterscheiden sich von den i;.blichen Absetzwiderständen im wesentlichen dadurch, daß der Widerstandsdraht statt auf Porzellankörpern auf einem isolierten Blechkern gewickelt ist. Vorzugsweise besteht der Blechkern aus geschichteten I-Blechschnitten.The chokes differ from the usual settling resistors essentially in that the resistance wire instead of on porcelain bodies is wrapped in an insulated sheet metal core. The sheet metal core preferably consists of layered I-sheet metal cuts.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.
Dem Brregerkreis des Synchrongenerators 1 wird von einer Gleichrichterbrücke 2 der Erregertrom zugeführt. Die Gleichrichterbrücke 2 wird dreiphasig von einem Stromtransformator 3 gespeist.The Brregerkreis of the synchronous generator 1 is from a rectifier bridge 2 is supplied with the excitation current. The rectifier bridge 2 is three-phase from one Current transformer 3 fed.
Zwischen dem Minuspol der Gleichrichterbrücke 2 und einer Phase des Stromtransformators 3 ist der Absetzwiderstandskreis 4 geschaltet. Er enthält einen vom Absetzregler 5 angesteuerten Thyristor 5a und beiderseits des Thyristors 5a je eine widerstandsbehaftete Drossel 6 mit einem ohmschen Anteil 6a und einem induktiven Anteil 6b.Between the negative pole of the rectifier bridge 2 and a phase of the Current transformer 3, the withdrawal resistor circuit 4 is connected. It contains one the thyristor 5a controlled by the settling regulator 5 and on both sides of the thyristor 5a a resistive choke 6 with an ohmic part 6a and an inductive part Share 6b.
Der ohmsche Anteil der aus um einen isolierten 1-Blechkern gewickelten Widerstandsdraht bestehenden Drossel unterbindet praktisch Eigenschwingungen der Drossel und wirkt wie ein üblicher Absetzwiderstand, wogegen der induktive Anteil die Anstiegsflanken des Stromes im Absetzwiderstandskreis so abflacht, daß Störspannnngen praktisch nicht entstehen können beim Schalten des Thyristors.The ohmic part of the wound around an insulated 1 sheet metal core Resistance wire prevents the existing choke practically natural vibrations Choke and acts like a normal withdrawal resistor, whereas the inductive component flattens the rising edges of the current in the settling resistor circuit so that interference voltages practically cannot arise when switching the thyristor.
