Description

Die vorliegende Erfindung betrifft einen Hochspannungs-Pulsgenerator für ein Elektrofilter,

  • mit einem Speicherkondensator, der über eine erste und eine zweite Zuleitung mit einer Hochspannungsquelle verbunden ist, wobei die zweite Zuleitung über einen ersten Knotenpunkt mit einem Bezugspotential verbunden ist,
  • mit einer Schalteinrichtung, die dem Speicherkondensator hochspannungsquellenseitig parallelgeschaltet ist,
  • und mit einer Ausgangsinduktivität, die über einen zweiten Knotenpunkt mit der zweiten Zuleitung verbunden ist, wobei der zweite Knotenpunkt zwischen dem Speicherkondensator und dem ersten Knotenpunkt angeordnet ist und wobei über die Ausgangsinduktivität ein Hochspannungs-Puls ausgebbar ist.
The present invention relates to a high-voltage pulse generator for an electrostatic filter,
  • with a storage capacitor which is connected to a high-voltage source via a first and a second feed line, the second feed line being connected to a reference potential via a first node,
  • with a switching device which is connected in parallel to the storage capacitor on the high voltage source side,
  • and with an output inductor which is connected to the second feed line via a second node, the second node being arranged between the storage capacitor and the first node and wherein a high-voltage pulse can be output via the output inductor.

Derartige Hochspannungs-Pulsgeneratoren sind allgemein bekannt. Sie werden beispielsweise dazu verwendet, bei elektrostatischen Staubabscheidern (Elektrofiltern) einer Gleichspannung zur Erhöhung der Abscheideleistung Spannungspulse zu überlagern.Such high-voltage pulse generators are generally known. They are used, for example, in electrostatic Dust collectors (electrostatic precipitators) of a DC voltage voltage pulses to increase the separation capacity overlap.

Auch aus der DE 199 46 786 A1 ist ein ähnlicher Hochspannungs-Pulsgenerator bekannt. Bei ihm ist zwischen den Knotenpunkten eine Induktivität angeordnet. Er weist aber keine Ausgangsinduktivität auf.A similar high-voltage pulse generator is also known from DE 199 46 786 A1 known. With him is between the nodes an inductor arranged. But he has none Output inductance.

Hochspannungs-Pulsgeneratoren werden durch Überschläge im Elektrofilter (Filterdurchschläge) oftmals stark belastet. Denn aufgrund der Filterdurchschläge werden große Spannungsund/oder Strompegel in den Pulsgenerator eingekoppelt. Die Einkopplung kann so stark sein, dass sie zur Zerstörung von Komponenten des Pulsgenerators, insbesondere der Schalteinrichtung, führt. Unter Umständen kann ein solcher Filterdurchschlag auch einen Anstieg der am Speicherkondensator anstehenden Spannung um mehrere 10 kV zur Folge haben, was zu einer Zerstörung des Speicherkondensators führen kann.High voltage pulse generators are caused by flashovers in the Electrostatic filters (filter breakthroughs) are often heavily loaded. Because of the filter breakdowns, large voltage and / or Current level coupled into the pulse generator. The Coupling can be so strong that it can destroy Components of the pulse generator, in particular the switching device, leads. Under certain circumstances, such a filter breakdown also an increase in the pending capacitor Result in voltage around several 10 kV, leading to can destroy the storage capacitor.

Wenn ein solcher Filterdurchschlag auftritt, während die Schalteinrichtung geschlossen ist, kann sogar ein hoher Kurzschlussstrom durch die Schalteinrichtung fließen. Hierdurch kann die Schalteinrichtung irreversibel geschädigt werden. Auch wird in einem solchen Fall die Lebensdauer des Speicherkondensators deutlich herabgesetzt.If such a filter breakdown occurs during the Switching device is closed, even a high short-circuit current flow through the switching device. hereby the switchgear can be irreversibly damaged. Also in such a case, the life of the storage capacitor significantly reduced.

Zur Vermeidung derartiger Schäden sind im Stand der Technik Schutzbeschaltungen, z. B. mit Varistoren, vorgesehen. Ferner werden die einzelnen Elemente des Pulsgenerators entsprechend dimensioniert, so dass sie auch derartige Filterdurchschläge verkraften. In der Folge sind die Pulsgeneratoren des Standes der Technik teuer.To avoid such damage are in the prior art Protection circuits, e.g. B. with varistors. Further the individual elements of the pulse generator are corresponding dimensioned so that they also have such filter breaks handle. As a result, the pulse generators of the stand technology expensive.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Hochspannungs-Pulsgenerator für ein Elektrofilter zu schaffen, der erheblich kostengünstiger herstellbar ist als Hochspannungs-Pulsgeneratoren des Standes der Technik.The object of the present invention is a To create high voltage pulse generator for an electrostatic precipitator which is much cheaper to produce than high-voltage pulse generators the state of the art.

Die Aufgabe wird dadurch gelöst, dass zwischen dem ersten und dem zweiten Knotenpunkt eine Diode angeordnet ist, die bezüglich eines von der Hochspannungsquelle in den Speicherkondensator fließenden Ladestromes in Durchlassrichtung angeordnet ist.The task is solved in that between the first and a diode is arranged at the second node, which is related to one from the high voltage source into the storage capacitor flowing charging currents arranged in the forward direction is.

Denn dadurch wird bei einem Filterdurchschlag ein Kurzschlusspfad niedriger Impedanz zur Verfügung gestellt, so dass ein Kurzschlussstrom von den übrigen Elementen des Hochspannungs-Pulsgenerators abgehalten wird. Gleichzeitig wird eine auf die übrigen Komponenten des Hochspannungs-Pulsgenerators wirkende Spannung auf die Durchlassspannung der Diode begrenzt. Gleichzeitig wird ein durch die Diode fließender Kurzschlussstrom durch die Ausgangsinduktivität begrenzt. Because this creates a short circuit path in the event of a filter breakdown low impedance provided so that a short circuit current from the other elements of the high voltage pulse generator is held. At the same time one on the other components of the high voltage pulse generator voltage acting on the forward voltage of the diode limited. At the same time, one flows through the diode Short-circuit current limited by the output inductance.

Wenn zwischen dem Speicherkondensator und dem zweiten Knotenpunkt ein Rückladestrombegrenzungselement angeordnet ist, werden Ströme von den übrigen Komponenten des Hochspannungs-Pulsgenerators besonders zuverlässig abgehalten. Das Rückladestrombegrenzungselement ist vorzugsweise als Induktivität ausgebildet.If between the storage capacitor and the second node a recharge current limiting element is arranged, currents from the other components of the high voltage pulse generator held particularly reliably. The recharge current limiting element is preferably as an inductor educated.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit der Zeichnungen und den weiteren Ansprüchen. Dabei zeigt die einzige

FIG 1
einen Hochspannungs-Pulsgenerator mit nachgeordnetem Elektrofilter.
Further advantages and details emerge from the following description of an exemplary embodiment in conjunction with the drawings and the further claims. The only one shows
FIG. 1
a high-voltage pulse generator with a downstream electrostatic filter.

Gemäß FIG 1 weist ein Hochspannungs-Pulsgenerator einen Speicherkondensator 1 auf, der über eine erste und eine zweite Zuleitung 2, 3 mit einer Hochspannungsquelle 4 verbunden ist. Dem Speicherkondensator 1 ist hochspannungsquellenseitig eine Schalteinrichtung 5 mit einer Freilaufdiodeneinrichtung 5' parallelgeschaltet.According to FIG. 1, a high-voltage pulse generator has a storage capacitor 1 on the first and second Lead 2, 3 is connected to a high voltage source 4. The storage capacitor 1 is a high voltage source Switching device 5 with a free-wheeling diode device 5 ' connected in parallel.

Einzelheiten der Schalteinrichtung 5 sind im Rahmen der vorliegenden Erfindung von untergeordneter Bedeutung. Bezüglich der Einzelheiten der Schalteinrichtung 5 wird auf die eingangs genannte DE 199 46 786 A1 verwiesen.Details of the switching device 5 are within the scope of the present Invention of minor importance. In terms of the details of the switching device 5 is based on the referred to DE 199 46 786 A1.

Die zweite Zuleitung 3 weist zwei Knotenpunkte 6, 7 auf. Über den ersten Knotenpunkt 6 ist die zweite Zuleitung 3 mit einem Bezugspotential verbunden. An den zweiten Knotenpunkt 7 ist eine Ausgangsinduktivität 8 angeschlossen. Zwischen den Knotenpunkten 6, 7 ist eine Diode 9 angeordnet.The second feed line 3 has two nodes 6, 7. about the first node 6 is the second feed line 3 with a Reference potential connected. At the second node 7 an output inductor 8 connected. Between the nodes 6, 7, a diode 9 is arranged.

In der ersten Zuleitung 2 ist zwischen der Hochspannungsquelle 4 und der Schalteinrichtung 5 ein Ladestrombegrenzungselement 10 angeordnet. Das Ladestrombegrenzungselement 10 ist gemäß FIG 1 als Kombination (hier Reihenschaltung) eines Widerstands mit einer Induktivität ausgebildet. Das Ladestrombegrenzungselement 10 könnte aber auch als reiner Widerstand oder als reine Induktivität ausgebildet sein.In the first lead 2 is between the high voltage source 4 and the switching device 5 a charging current limiting element 10 arranged. The charging current limiting element 10 is 1 as a combination (here series connection) of a resistor formed with an inductor. The charging current limiting element 10 could also be a pure resistance or be designed as a pure inductor.

Vom Hochspannungs-Pulsgenerator ist über die Ausgangsinduktivität 8 und einen dieser nachgeschalteten Entkoppelkondensator 11 ein Hochspannungspuls an ein nur schematisch dargestelltes Elektrofilter 12 ausgebbar. Das Elektrofilter 12 ist dabei über eine eigene Hochspannungsquelle 13 mit einer Gleichspannung im Bereich von mehreren 10 kV vorgeladen. Der Gleichspannungspegel des Elektrofilters 12 ist über den Entkoppelkondensator 11 von dem Hochspannungs-Pulsgenerator abgekoppelt.From the high voltage pulse generator is about the output inductance 8 and one of these decoupling capacitors 11 a high-voltage pulse to a only schematically shown Electrofilter 12 can be output. The electrostatic filter 12 is thereby via its own high-voltage source 13 with a DC voltage pre-charged in the range of several 10 kV. The DC voltage level of the electrostatic filter 12 is via the decoupling capacitor 11 decoupled from the high-voltage pulse generator.

Wenn die Schalteinrichtung 5 geöffnet ist, wird der Speicherkondensator 1 über die Zuleitungen 2, 3 mit einem Ladestrom I geladen. Hierfür ist die Diode 9 in Durchlassrichtung gepolt. Wenn die Schalteinrichtung 5 geschlossen wird, wird der Speicherkondensator 1 entladen, wodurch die am Elektrofilter 12 anstehende Spannung erhöht wird.When the switching device 5 is open, the storage capacitor 1 via the supply lines 2, 3 with a charging current I loaded. For this purpose, the diode 9 is polarized in the forward direction. When the switching device 5 is closed, the storage capacitor 1 discharged, whereby the on the electrostatic filter 12th applied voltage is increased.

Bezüglich des Entladens des Speicherkondensators 1 ist die Diode 9 in Sperrrichtung gepolt. Der Speicherkondensator 1 entlädt sich daher ausschließlich über die Induktivität 14 und die Ausgangsinduktivität 8. Die Induktivität 14 dient als Rückladestrombegrenzungselement 14 und ist zwischen dem Speicherkondensator 1 und dem zweiten Knotenpunkt 7 angeordnet.Regarding the discharge of the storage capacitor 1, the Diode 9 polarized in the reverse direction. The storage capacitor 1 therefore discharges exclusively via the inductor 14 and the output inductance 8. The inductance 14 serves as Recharge current limiting element 14 and is between the storage capacitor 1 and the second node 7 arranged.

Nach dem Aufladen des Elektrofilters 12 fließt ein Teil der Ladung über die Ausgangsinduktivität 8 zurück. Der Strom fließt dann aber nicht über das Rückladestrombegrenzungselement 14, sondern im wesentlichen über die Diode 9 und die Freilaufdiodeneinrichtung 5'. Auch hierfür ist die Diode 9 in Durchlassrichtung gepolt.After charging the electrostatic filter 12, part of the flows Charge back through the output inductor 8. The current but then does not flow through the reverse current limiting element 14, but essentially via the diode 9 and the Free-wheeling diode device 5 '. The diode 9 in is also for this Polarized forward direction.

Auch bei einem Filterdurchschlag fließt ein Kurzschlussstrom im wesentlichen lediglich über die Ausgangsinduktivität 8 und die Diode 9. Auf die übrigen Komponenten des Pulsgenerators wird lediglich eine Spannung durchgelassen, die der Durchlassspannung der Diode 9 entspricht. Die Spannungsbegrenzung gilt dabei unabhängig davon, ob die Schalteinrichtung 5 geöffnet oder geschlossen ist. Auch ein etwaiger über die Schalteinrichtung 5 fließender Kurzschlussstrom wird daher durch die Durchlassspannung auf einem niedrigen Niveau gehalten und darüber hinaus durch das Rückladestrombegrenzungselement 14 noch weiter gedämpft.A short-circuit current also flows in the event of a filter breakdown essentially only via the output inductance 8 and the diode 9. On the other components of the pulse generator only a voltage is let through that of the forward voltage corresponds to the diode 9. The voltage limitation applies regardless of whether the switching device 5 is open or is closed. Any about the Switching device 5 flowing short circuit current is therefore kept at a low level by the forward voltage and furthermore by the recharge current limiting element 14 dampened even further.

Der erfindungsgemäße Hochspannungs-Pulsgenerator ist somit unter Verwendung lediglich einer Hochspannungsdiode 9 zwischen den beiden Knotenpunkten 6, 7 hochspannungsfest ausgebildet. Der Speicherkondensator 1 und die Schalteinrichtung 5 können daher erheblich kostengünstiger dimensioniert werden als bei einem vergleichbaren Hochspannungs-Pulsgenerator des Standes der Technik. Die Verlustleistung des erfindungsgmäßen Hochspannungs-Pulsgenerators ist erheblich geringer als die Verlustleistung eines vergleichbaren Pulsgenerators, bei dem zwischen den Knotenpunkten 6, 7 ein Widerstand oder eine Induktivität angeordnet ist. Darüber hinaus können bei dem erfindungsgemäßen Pulsgenerator keine parasitären Schwingungen mit Hochspannungsamplituden von mehr als 10 kV entstehen, was bei Pulsgeneratoren, bei denen zwischen den beiden Knotenpunkten 6, 7 eine Induktivität angeordnet ist, der Fall ist.The high-voltage pulse generator according to the invention is thus using only a high voltage diode 9 between the two nodes 6, 7 are designed to withstand high voltages. The storage capacitor 1 and the switching device 5 can therefore be dimensioned significantly cheaper than in a comparable high-voltage pulse generator State of the art. The power loss of the Invention High voltage pulse generator is considerably less than that Power loss of a comparable pulse generator, in which a resistance or an inductance between the nodes 6, 7 is arranged. In addition, the inventive Pulse generator no parasitic vibrations with high voltage amplitudes of more than 10 kV arise what for pulse generators, in which between the two nodes 6, 7 an inductor is arranged, the case is.
