Description

Die Erfindung betrifft einen selbstauslösenden Stromunterbrecher für Kurzschlussströme.The invention relates to a self-releasing circuit breaker for short-circuit currents.

Bei Auftreten einer Kurzschlussverbindung fließt ein hoher elektrischer Strom, der ein Mehrfaches eines normalen Betriebsstromes betragen kann. Kurzschlüsse können beispielsweise durch schadhaft gewordene Isolation oder durch einen Schaltfehler in elektrischen Anlagen verursacht werden. Derartige Kurzschlussströme können durch Schutzeinrichtungen erfasst werden und die stromführenden Leiter durch Leistungsschalter bzw. durch Sicherung ausgeschaltet werden. Kurzschlüsse können verschiedene Ursachen haben. Oft werden Kurzschlüsse durch einen Isolationsbruch oder durch Isolationsänderungen hervorgerufen. Auch Fehlschaltungen in elektrischen Schaltanlagen und Geräten sowie die Nichtbeachtung von Sicherheitsregeln können zu Kurzschlüssen führen. Durch eine fehlende Begrenzung eines Kurzschlussstromes kann es zu Schäden durch Überhitzung im Leitungsverlauf oder von elektrischen Schaltanlagenkomponenten kommen. Zur Verhinderung der Folgen von elektrischen Kurzschlüssen können beispielsweise in Niederspannungsnetzen Schutzschalter und Schmelzsicherungen eingesetzt werden. Je nach Anwendungsfall muss das Schalten des Stromunterbrechers mit ausreichender Geschwindigkeit erfolgen.When a short-circuit connection occurs, a high electric current flows, which can amount to a multiple of a normal operating current. Short circuits can be caused, for example, by faulty isolation or by a switching error in electrical systems. Such short-circuit currents can be detected by protective devices and the current-carrying conductors are switched off by circuit breakers or by fuse. Short circuits can have different causes. Often short circuits are caused by a broken insulation or by insulation changes. Faulty circuits in electrical switchgear and devices as well as non-compliance with safety regulations can lead to short-circuits. Failure to limit a short-circuit current can cause overheating in the line or electrical components. To prevent the consequences of electrical short circuits, for example, in low-voltage networks circuit breakers and fuses can be used. Depending on the application, the circuit breaker must be switched at a sufficient speed.

Fig. 1 zeigt eine Ansicht eines möglichen Ausführungsbeispiels eines erfindungsgemäßen Stromunterbrechers 1 gemäß einem ersten Aspekt der Erfindung. Man erkennt in Fig. 1 einen ersten Festkontakt 2 und einen zweiten Festkontakt 3. Die beiden Festkontakte 2, 3 werden in dem dargestellten Ausführungsbeispiel durch Enden von Spulenleiterbändern 4, 5 gebildet. Die Spulenleiterbänder 4, 5 sind jeweils um einen Wickel-Hohlraum 6, 7 gewickelt. In den beiden Wickel-Hohlräumen 6, 7 befindet sich jeweils ein Kontaktschenkel 8, 9 einer Kontaktwippe 10, wobei die beiden Kontaktschenkel 8, 9 der Kontaktwippe 10 über einen Verbindungssteg 11 miteinander verbunden sind, wie in Fig. 1 dargestellt. Bei dem dargestellten Ausführungsbeispiel ist somit die Kontaktwippe 10 U-förmig ausgebildet und weist zwei Kontaktschenkel 8, 9 auf, die sich in Wickel-Hohlräumen 6, 7 zweier Spulen 12, 13 befinden. Die erste Spule 12 wird durch das um den Wickel-Hohlraum 6 gewickelte erste Spulenleiterband 4 gebildet. Die zweite Spule 13 wird durch das um den Wickel-Hohlraum 7. herumgewickelte Spulenleiterband 5 gebildet. Die Spulenleiterbänder 4, 5 weisen eine Breite B auf, wie in Fig. 1 dargestellt. Bei einer möglichen Ausführungsform liegt die Breite B der Spulenleiterbänder 4, 5 in einem Bereich von 1 bis 2 cm, beispielsweise 1,5 bis 1,6 cm. Die Spulenleiterbänder 4, 5 sind mehrfach um den zugehörigen Wickel-Hohlraum 6, 7 herumgewickelt. Bei einer möglichen Ausführungsform sind die gewickelten Spulenleiterbänder 4, 5 der beiden Spulen 12, 13 jeweils 5 bis 10 Mal um den zugehörigen Wickel-Hohlraum 6, 7 der jeweiligen Spule 12, 13 herumgewickelt. Fig. 1 shows a view of a possible embodiment of a circuit breaker 1 according to the invention according to a first aspect of the invention. One recognizes in Fig. 1 a first fixed contact 2 and a second fixed contact 3. The two fixed contacts 2, 3 are formed in the illustrated embodiment by ends of coil conductor strips 4, 5. The coil conductor strips 4, 5 are each wound around a winding cavity 6, 7. In the two winding cavities 6, 7 are each a contact leg 8, 9 of a contact rocker 10, wherein the two contact legs 8, 9 of the contact rocker 10 are connected to each other via a connecting web 11, as in Fig. 1 shown. In the illustrated embodiment, thus, the contact rocker 10 is U-shaped and has two contact legs 8, 9, which are in winding cavities 6, 7 of two coils 12, 13. The first coil 12 is formed by the wound around the winding cavity 6 first coil conductor tape 4. The second coil 13 is formed by the wound around the winding cavity 7. coil conductor strip 5. The coil conductor strips 4, 5 have a width B, as in Fig. 1 shown. In one possible embodiment, the width B of the coil conductor strips 4, 5 is in a range of 1 to 2 cm, for example 1.5 to 1.6 cm. The coil conductor strips 4, 5 are wound around the associated winding cavity 6, 7 several times. In one possible embodiment, the wound coil conductor strips 4, 5 of the two coils 12, 13 are each wound 5 to 10 times around the associated winding cavity 6, 7 of the respective coil 12, 13.

Der erste Festkontakt 2, welcher durch das Ende des Spulenleiterbandes 4 gebildet wird, ist über das gewickelte Spulenleiterband 4 elektrisch mit einem Stromzugang des Stromunterbrechers 1 verbunden. Der zweite Festkontakt 3, welcher durch das Ende des zweiten Spulenleiterbandes 5 gebildet wird, ist über das gewickelte Spulenleiterband 5 mit einem Stromabgang des Stromunterbrechers 1 verbunden. Der Stromzugang leitet einen elektrischen Strom I über das erste gewickelte Spulenleiterband 4 der ersten Spule 12 an den ersten Festkontakt 2. Im normalen Betrieb, d.h. vor Auftreten eines hohen elektrischen Stromes bzw. Kurzschlussstromes, liegt das distale Ende 14 des ersten Kontaktschenkels 8 der U-förmigen Kontaktwippe 10 an dem ersten Festkontakt 2 an. In gleicher Weise liegt in dem normalen Betrieb das distale Ende 15 des zweiten Kontaktschenkels 9 der U-förmigen Kontaktwippe 10 an dem zweiten Festkontakt 3 an. In dieser Schaltstellung sind somit die beiden Festkontakte 2, 3 über die beiden Kontaktschenkel 8, 9 und den Verbindungssteg 11 der U-förmigen Kontaktwippe 10 miteinander elektrisch verbunden. Der Verbindungssteg 11 sowie die beiden Kontaktschenkel 8, 9 der U-förmigen Kontaktwippe 10 bestehen aus einem elektrisch leitenden Material. Der von dem Stromzugang über das erste Spulenleiterband 4 zu dem ersten Festkontakt 2 fließende elektrische Strom I fließt über die Kontaktschenkel 8, 9 und den dazwischenliegenden Verbindungssteg 11 zu dem zweiten Festkontakt 3 und von dort über den Stromabgang des Stromunterbrechers 1 ab. Der Stromunterbrecher 1 verbleibt in dieser normalen Schaltstellung, solange der hindurchfließende elektrische Strom I einen gewissen Stromschwellenwert nicht überschreitet.The first fixed contact 2, which is formed by the end of the coil conductor band 4, is electrically connected via the wound coil conductor band 4 to a current input of the circuit breaker 1. The second fixed contact 3, which is formed by the end of the second coil conductor strip 5, is connected via the wound coil conductor strip 5 to a current outlet of the circuit breaker 1. The power access passes During normal operation, ie before the occurrence of a high electric current or short-circuit current, the distal end 14 of the first contact leg 8 of the U-shaped contact rocker 10 is located on the first fixed contact 2. In the same way, in the normal operation, the distal end 15 of the second contact leg 9 of the U-shaped contact rocker 10 abuts against the second fixed contact 3. In this switching position thus the two fixed contacts 2, 3 are electrically connected to each other via the two contact legs 8, 9 and the connecting web 11 of the U-shaped contact rocker 10. The connecting web 11 and the two contact legs 8, 9 of the U-shaped contact rocker 10 are made of an electrically conductive material. The electrical current I flowing from the current access via the first coil conductor strip 4 to the first fixed contact 2 flows via the contact legs 8, 9 and the intermediate connecting web 11 to the second fixed contact 3 and from there via the current outlet of the circuit breaker 1. The circuit breaker 1 remains in this normal switching position, as long as the electrical current flowing through I does not exceed a certain current threshold.

Ein hoher elektrischer Strom I, insbesondere ein Kurzschlussstrom, welcher durch die gewickelten Spulenleiterbände 4, 5 der beiden Spulen 12, 13 sowie durch die beiden Kontaktschenkel 8, 9 der Kontaktwippe 10 hindurchfließt, ruft ein Magnetfeld B hervor, das unmittelbar eine Schaltkraft F erzeugt, welche die Kontaktwippe 10 mit einer hohen Schaltgeschwindigkeit von der ersten Schaltstellung, bei der die beiden Festkontakte 2, 3 über die Kontaktwippe 10 miteinander verbunden sind, in eine zweite Schaltstellung bewegt, in welcher die beiden Festkontakte 2, 3 elektrisch getrennt und der elektrische Strom I unterbrochen ist. Bei einer möglichen Ausführungsform beträgt die Schaltdauer, mit welcher die Kontaktwippe 10 bei Auftreten eines hohen Stromes, insbesondere eines Kurzschlussstromes, von der ersten Schaltstellung in die zweite Schaltstellung bewegt wird, weniger als 0,1 msec.A high electric current I, in particular a short-circuit current, which flows through the wound Spulenleiterbände 4, 5 of the two coils 12, 13 and through the two contact legs 8, 9 of the contact rocker 10, causes a magnetic field B, which directly generates a switching force F, which the contact rocker 10 with a high switching speed of the first switching position, in which the two fixed contacts 2, 3 are connected to each other via the contact rocker 10 moves to a second switching position, in which the two fixed contacts 2, 3 electrically separated and the electric current I. is interrupted. In one possible embodiment, the switching duration with which the contact rocker 10 when a high current, in particular a Short circuit current is moved from the first switching position to the second switching position, less than 0.1 msec.

Bei der in Fig. 1 dargestellten Ausführungsform sind die gewickelten Spulenleiterbänder 4, 5 der beiden Spulen 12, 13 jeweils um den langgezogenen Wickel-Hohlraum 6, 7 gewickelt, wobei jede Wicklung zwei einander gegenüberliegende längliche Spulenleiterabschnitte aufweist, nämlich einen oberen Spulenleiterbandabschnitt und einen unteren Spulenleiterbandabschnitt, die im Wesentlichen parallel zu dem in dem Wickel-hohlraum angeordneten Kontaktschenkel 8, 9 der U-förmigen Kontaktwippe 10 verlaufen. Ein elektrischer Strom I, welcher durch das gewickelte Spulenleiterband 4, 5 einer der beiden Spulen 12, 13 und durch den in dem Wickel-Hohlraum 6, 7 der jeweiligen Spule 12, 13 angeordneten Kontaktschenkel 8, 9 der Kontaktwippe 10 hindurchfließt, ruft aufgrund der gleichen Stromflussrichtung eine Anziehungskraft F1 zwischen dem Kontaktschenkel 8, 9 und einem ersten Spulenleiterbandabschnitt des jeweiligen gewickelten Spulenleiterbandes 4, 5 der jeweiligen Spule 12, 13 und aufgrund der entgegengesetzten Stromflussrichtung eine Abstoßungskraft F2 zwischen dem Kontaktschenkel 8, 9 und einem zweiten gegenüberliegenden Spulenleiterbandabschnitt des gewickelten Spulenleiterbandes der jeweiligen Spule 12, 13 hervor. Wie man in Fig. 1 erkennen kann, fließt der elektrische Strom I in der ersten normalen Schaltstellung des Stromunterbrechers 1 von dem ersten Festkontakt 2 über den Kontaktschenkel 8 in Richtung hin zu dem Verbindungssteg 11 und somit parallel zu dem elektrischen Strom, der durch den oberen Spulenleiterbandabschnitt des gewickelten Spulenleiterbandes 4 der ersten Spule 12 fließt. Der Kontaktschenkel 8 wird aufgrund des gebildeten Magnetfeldes demzufolge durch den oberen Spulenleiterbandabschnitt der ersten Spule 12 nach oben mit einer Anziehungskraft F1 angezogen. In gleicher Weise ist aus Fig. 1 erkennbar, dass der durch den unteren Spulenleiterbandabschnitt des Spulenleiterbandes 4 der ersten Spule 12 hindurchfließende Strom I antiparallel bzw. entgegengesetzt zu dem über den ersten Kontaktschenkel 8 fließenden Strom I fließt und somit aufgrund des Magnetfeldes eine Abstoßungskraft F2 hervorruft. Der Kontaktschenkel 8 wird somit einerseits durch den parallel fließenden Strom I durch den oberen Spulenleiterbandabschnitt der ersten Spule 12 angezogen und gleichzeitig von dem unteren Spulenleiterbandabschnitt der ersten Spule 12 abgestoßen. Die Anziehungskraft F1 und die Abstoßungskraft F2 haben somit die gleiche Richtung und führen bei einem ausreichend hohen elektrischen Strom bzw. einem Strom mit einer genügend hohen Stromamplitude dazu, dass der Kontaktschenkel 8 aufgrund der erzeugten summierten Schaltkraft F(F=F1+F2) mit einer sehr hohen Schaltgeschwindigkeit von der ersten Schaltstellung in eine zweite Schaltstellung bewegt wird, in welcher der Kontaktschenkel 8 von dem ersten Festkontakt 2 getrennt ist und somit der elektrische Strom I unterbrochen ist. Das Öffnen des zweiten Kontaktschenkels 9 erfolgt aufgrund der durch die Spulenleiterbandabschnitte der zweiten Spule 13 parallel bzw. antiparallel fließenden Ströme in gleicher Weise, d.h., der obere Spulenleiterbandabschnitt des zweiten Spulenleiterbandes 5 der zweiten Spule 13 übt eine Anziehungskraft F1 auf den Kontaktschenkel 9 aus, während der untere Spulenleiterbandabschnitt des zweiten Spulenleiterbandes 5 der zweiten Spule 13 eine Abstoßungskraft F2 auf den Kontaktschenkel 9 aufgrund des gebildeten Magnetfeldes erzeugt.At the in Fig. 1 In the illustrated embodiment, the wound coil conductors 4, 5 of the two coils 12, 13 are respectively wound around the elongated winding cavity 6, 7, each winding having two opposing elongated coil conductor sections, namely an upper coil conductor section and a lower coil conductor section substantially parallel to the arranged in the winding cavity contact legs 8, 9 of the U-shaped contact rocker 10 extend. An electric current I, which flows through the wound coil conductor strip 4, 5 of one of the two coils 12, 13 and through the arranged in the winding cavity 6, 7 of the respective coil 12, 13 contact legs 8, 9 of the contact rocker 10, calls due to same current flow direction, an attractive force F 1 between the contact leg 8, 9 and a first Spulenleiterbandabschnitt the respective wound coil conductor tape 4, 5 of the respective coil 12, 13 and due to the opposite direction of current flow repulsive force F 2 between the contact legs 8, 9 and a second opposing coil conductor portion of the wound Spulenleiterbandes the respective coil 12, 13. How to get in Fig. 1 can recognize the electric current I flows in the first normal switching position of the circuit breaker 1 of the first fixed contact 2 via the contact leg 8 toward the connecting web 11 and thus parallel to the electric current through the upper coil conductor tape portion of the wound coil conductor tape 4 of first coil 12 flows. The contact leg 8 is therefore attracted by the magnetic field formed by the upper Spulenleiterbandabschnitt the first coil 12 up with an attractive force F 1 . In the same way is off Fig. 1 it can be seen that the current I flowing through the lower coil conductor strip section of the coil conductor strip 4 of the first coil 12 is antiparallel or opposite to that via the first contact leg 8 flowing current I flows and thus causes a repulsive force F 2 due to the magnetic field. The contact leg 8 is thus attracted on the one hand by the parallel current I flowing through the upper coil conductor band portion of the first coil 12 and repelled simultaneously from the lower coil conductor band portion of the first coil 12. The attractive force F 1 and the repulsive force F 2 thus have the same direction and, given a sufficiently high electric current or a current with a sufficiently high current amplitude, causes the contact leg 8 to become due to the summed switching force F (F = F 1 + F 2 ) is moved with a very high switching speed of the first switching position in a second switching position, in which the contact leg 8 is separated from the first fixed contact 2 and thus the electric current I is interrupted. The opening of the second contact leg 9 takes place in the same way due to the currents flowing parallel or antiparallel through the coil conductor strip sections of the second coil 13, ie, the upper coil conductor strip section of the second coil conductor strip 5 of the second coil 13 exerts an attractive force F 1 on the contact leg 9, while the lower coil conductor band portion of the second coil conductor band 5 of the second coil 13 generates a repulsive force F 2 on the contact leg 9 due to the generated magnetic field.

Der Verbindungssteg 11 der U-förmigen Kontaktwippe 10 ist vorzugsweise zum Bereitstellen von stabilen Endlagen der Kontaktwippe 10 in beiden Schaltstellungen mechanisch gelagert, wie in Fig. 1 dargestellt. An dem Verbindungssteg 11 der U-förmigen Kontaktwippe 10 ist eine Halterung 16 vorgesehen, die mittels Federn stabile Endlagen der U-förmigen Kontaktwippe 10 in beiden Schaltstellungen bereitstellt. Im Normalbetrieb ist die Amplitude des über den Stromunterbrecher 1 fließenden elektrischen Stromes I so gering, dass sich die U-förmige Kontaktwippe 10 in der unteren stabilen Endlage befindet und die beiden Festkontakte 2, 3 miteinander elektrisch verbindet. Bei Auftreten eines hohen elektrischen Stromes bzw. Kurzschlussstromes wird die U-förmige Kontaktwippe 10 durch die hervorgerufenen Magnetfeldkräfte mit hoher Schaltgeschwindigkeit in die andere stabile Endlage verbracht, in der die beiden Festkontakte 2, 3 voneinander elektrisch getrennt sind. Die Anzahl der Wicklungen der beiden Spulenleiterbänder 4, 5 der beiden Spulen 12, 13 kann je nach Anwendungsfall für unterschiedliche Stromstärken unterschiedlich ausgelegt sein. Je mehr Wicklungen die beiden Spulen 12, 13 aufweisen, desto höher sind die durch den hindurchfließenden Strom I hervorgerufenen Anziehungs- bzw. Abstoßungskräfte, die auf die Kontaktschenkel 8, 9 der Kontaktwippe 10 wirken, sodass der Stromunterbrecher 1 bereits bei geringeren Stromstärken auslöst. Bei Auftreten eines Kurzschlussstromes wird eine Freiauslösung des Stromunterbrechers 1 bewirkt. Unter Freiauslösung versteht man den Mechanismus, welcher das Wiedereinschalten einer Anlage oder eines Gerätes verhindert, solange die Ursache der Abschaltung noch besteht. Der erfindungsgemäße Stromunterbrecher 1, wie er in Fig. 1 dargestellt ist, ist vorzugsweise symmetrisch aufgebaut und weist zwei Spulen 12, 13 auf, die jeweils einen Kontaktschenkel 8, 9 der U-förmigen Kontaktwippe 10 umschließen. Bei alternativen Ausführungsformen kann die Kontaktwippe auch eine größere Anzahl von Kontaktschenkeln aufweisen, die jeweils durch eine zugehörige Spule umschlossen werden.The connecting web 11 of the U-shaped contact rocker 10 is preferably mechanically mounted for providing stable end positions of the contact rocker 10 in both switching positions, as in Fig. 1 shown. At the connecting web 11 of the U-shaped contact rocker 10, a holder 16 is provided which provides stable end positions of the U-shaped contact rocker 10 in both switching positions by means of springs. In normal operation, the amplitude of the current interruptor 1 flowing through the electric current I is so low that the U-shaped contact rocker 10 is in the lower stable end position and the two fixed contacts 2, 3 electrically connected together. When a high electrical Current or short-circuit current, the U-shaped contact rocker 10 is spent by the induced magnetic forces at high switching speed in the other stable end position in which the two fixed contacts 2, 3 are electrically isolated from each other. The number of windings of the two Spulenleiterbänder 4, 5 of the two coils 12, 13 may be designed differently depending on the application for different currents. The more windings the two coils 12, 13 have, the higher are the attraction or repulsion forces caused by the current I flowing through which act on the contact legs 8, 9 of the contact rocker 10, so that the circuit breaker 1 already triggers at lower current intensities. When a short-circuit current occurs, a free trip of the circuit breaker 1 is effected. Free release is the mechanism that prevents the reconnection of a system or a device as long as the cause of the shutdown still exists. The circuit breaker 1 according to the invention, as in Fig. 1 is shown, is preferably constructed symmetrically and has two coils 12, 13, each enclosing a contact legs 8, 9 of the U-shaped contact rocker 10. In alternative embodiments, the contact rocker may also have a larger number of contact legs, each enclosed by an associated coil.

Fig. 2 zeigt ein Blockschaltbild einer möglichen Ausführungsform einer erfindungsgemäßen Schaltvorrichtung 17, die einen selbstauslösenden Stromunterbrecher 1 enthält. Der Stromunterbrecher 1 ist ein selbstauslösender mechanischer Schalter, der mit hoher Schaltgeschwindigkeit schaltet. Bei der erfindungsgemäßen Schaltvorrichtung 17 ist zur Unterdrückung eines Lichtbogens beim Öffnen des Stromunterbrechers 1 parallel zu dem Stromunterbrecher 1 ein steuerbarer Halbleiterschalter 18 vorgesehen. Der steuerbare Halbleiterschalter 18 ist beispielsweise ein Thyristor oder dergleichen. Der Stromzugang 19 des Stromunterbrechers 1 und der Stromabgang 20 des Stromunterbrechers 1 ist jeweils mit zugehörigen Anschlüssen 21, 22 der Schaltvorrichtung 17 verbunden, wie in Fig. 2 dargestellt. Wie in Fig. 2 dargestellt, ist der Halbleiterschalter 18, beispielsweise ein Thyristor, parallel zu dem Stromunterbrecher 1 verschaltet. Der steuerbare Halbleiterschalter 18 wird bei Auftreten eines hohen Stromes I, insbesondere eines Kurzschlussstromes, durchgeschaltet. Der parallel verschaltete Halbleiterschalter 18 wird nach einer vorbestimmten Zeit gesperrt. Bei der in Fig. 2 dargestellten Ausführungsform enthält die Schaltvorrichtung 17 eine integrierte Steuerschaltung 23, die das Auftreten eines hohen Stromes, insbesondere eines Kurzschlussstromes, sensorisch erfasst. Fig. 2 shows a block diagram of a possible embodiment of a switching device 17 according to the invention, which contains a self-triggering circuit breaker 1. The circuit breaker 1 is a self-triggering mechanical switch that switches at a high switching speed. In the case of the switching device 17 according to the invention, a controllable semiconductor switch 18 is provided parallel to the circuit breaker 1 for suppressing an arc when the circuit breaker 1 is opened. The controllable semiconductor switch 18 is, for example, a thyristor or the like. The current access 19 of the circuit breaker 1 and the current outlet 20 of the circuit breaker 1 is in each case with associated terminals 21, 22 of the switching device 17, as in Fig. 2 shown. As in Fig. 2 1, the semiconductor switch 18, for example a thyristor, is connected in parallel to the circuit breaker 1. The controllable semiconductor switch 18 is switched on occurrence of a high current I, in particular a short-circuit current. The parallel-connected semiconductor switch 18 is disabled after a predetermined time. At the in Fig. 2 In the illustrated embodiment, the switching device 17 includes an integrated control circuit 23, which senses the occurrence of a high current, in particular a short-circuit current.

Die Funktionsweise der in Fig. 2 dargestellten Schaltvorrichtung 17 mit dem darin enthaltenen Stromunterbrecher 1 und dem dazu parallel verschalteten Halbleiterschalter 18 wird anhand des Spannungsverlaufs gemäß Fig. 3 näher erläutert. Zunächst fließt im Normalbetrieb ein elektrischer Strom I über den geschlossenen Stromunterbrecher 1 von einem Stromeingang 21 direkt zu einem Stromausgang 22 der Schaltvorrichtung 17. Die Schaltvorrichtung 17 ist symmetrisch aufgebaut, d.h. Stromeingang 21 und Stromausgang 22 sind austauschbar. Im Normalbetrieb fließt der Strom über den mechanischen Stromunterbrecher 1, wobei dort nur eine geringe Spannung U1 abfällt, wie in Fig. 3 dargestellt. Die Spannung U1 kann beispielsweise 0,1 Volt betragen. Zu einem Zeitpunkt t1 tritt ein Kurzschlussstrom auf, welcher aufgrund der erzeugten Magnetfeldkräfte mit einer hohen Schaltkraft die Kontaktwippe 10 des Stromunterbrechers 1 in die andere Schaltstellung bewegt und somit zu einem Öffnen des Stromunterbrechers 1 führt. Die aufgetretenen Kräfte wirken hierbei direkt auf die beweglichen Schaltkontakte bzw. die Kontaktschenkel der Kontaktwippe 10. Beim Öffnen des Stromunterbrechers 1 steigt die Spannung 11 schnell auf einen höheren Spannungswert U2, beispielsweise 20 Volt, an. Die ansteigende Spannung wird durch die Steuerschaltung 23 der Schaltvorrichtung 17 erkannt, wobei die Steuervorrichtung 23 ab einem gewissen Schwellenwert den parallel geschalteten Halbleiterschalter 18 mit einer gewissen Zeitverzögerung zu einem Zeitpunkt t2 an- bzw. durchschaltet. Hierdurch sinkt die Spannung 11 auf einen geringeren Spannungswert U3, beispielsweise eine Spannung von 2 Volt, ab. Das Durchschalten des Halbleiterschalters 18 unterdrückt das Auftreten eines Lichtbogens bei dem mechanischen Stromunterbrecher 1 und führt somit zu einer deutlichen Schonung des Stromunterbrechers 1 bzw. zu einem geringeren Verschleiß. Zu einem Zeitpunkt t3 wird der steuerbare Halbleiterschalter 18 durch die integrierte Steuerschaltung 23 aus- bzw. abgeschaltet und die Spannung steigt auf einen hohen Spannungswert U4 an. Zu dem Zeitpunkt t3 sind sowohl der Halbleiterschalter 18 als auch der Stromunterbrecher 1 geöffnet bzw. getrennt, sodass kein Strom I mehr zwischen den Stromanschlüssen 21, 22 der Schaltvorrichtung 17 fließt. Die Schaltflanke zum Zeitpunkt t1 ist aufgrund des besonderen Aufbaus des in Fig. 1 dargestellten Stromunterbrechers 1 besonders steil, d.h., die Schaltdauer zum mechanischen Schalten ist sehr gering und liegt vorzugsweise unter 0,1 msec. Die Reaktionszeit zum Durchschalten des Halbleiterschalters 18 zum Zeitpunkt t2 wird vorzugsweise ebenfalls minimiert, um das Auftreten eines Lichtbogens an dem mechanischen Schalter 1 zu verhindern. Bei einer möglichen Ausführungsform spricht der selbstauslösende Stromunterbrecher 1 an, wenn das Verhältnis des momentan fließenden Stromes I, insbesondere Kurzschlussstromes IK, zu einem Normalstrom INORM ein gewisses Verhältnis überschreitet. Bei einer möglichen Ausführungsform spricht der selbstauslösende Stromunterbrecher 1 an, wenn das Verhältnis zwischen Kurzschlussstrom IK und einem Normalstrom INORM ≥ 20 ist. Dieses Verhältnis kann in Abhängigkeit von der besonderen Geometrie der Spulen 12, 13 und der Anzahl der Spulenwicklungen sowie der Ausgestaltung der Schalt- bzw. Kontaktwippe 10 für unterschiedliche Anwendungsfälle unterschiedlich ausgelegt werden.The functioning of in Fig. 2 illustrated switching device 17 with the circuit breaker 1 contained therein and the semiconductor switch 18 connected in parallel thereto is determined by the voltage curve according to Fig. 3 explained in more detail. First, in normal operation, an electric current I flows via the closed circuit breaker 1 from a current input 21 directly to a current output 22 of the switching device 17. The switching device 17 is constructed symmetrically, ie current input 21 and current output 22 are interchangeable. In normal operation, the current flows through the mechanical circuit breaker 1, where only a low voltage U1 drops there, as in Fig. 3 shown. The voltage U1 can be for example 0.1 volts. At a time t1 occurs a short-circuit current, which moves the contact rocker 10 of the circuit breaker 1 in the other switching position due to the magnetic field forces generated with a high switching force and thus leads to an opening of the circuit breaker 1. The forces that occur act directly on the movable switching contacts or the contact legs of the contact rocker 10. When opening the circuit breaker 1, the voltage 11 rises rapidly to a higher voltage value U2, for example, 20 volts to. The rising voltage is detected by the control circuit 23 of the switching device 17, wherein the control device 23 from a certain threshold, the parallel-connected semiconductor switch 18 with a certain Time delay at a time t2 on or turns on. As a result, the voltage 11 drops to a lower voltage value U3, for example, a voltage of 2 volts from. Switching through the semiconductor switch 18 suppresses the occurrence of an arc in the mechanical circuit breaker 1 and thus leads to a significant protection of the circuit breaker 1 and to a lower wear. At a time t3, the controllable semiconductor switch 18 is switched off or switched off by the integrated control circuit 23 and the voltage rises to a high voltage value U4. At the time t3, both the semiconductor switch 18 and the circuit breaker 1 are opened and disconnected, so that no more current I flows between the power terminals 21, 22 of the switching device 17. The switching edge at time t1 is due to the special structure of in Fig. 1 illustrated circuit breaker 1 particularly steep, ie, the switching time for mechanical switching is very low and is preferably less than 0.1 msec. The response time for turning on the semiconductor switch 18 at time t2 is also preferably minimized to prevent the occurrence of an arc on the mechanical switch 1. In one possible embodiment, the self-triggering circuit breaker 1 responds when the ratio of the instantaneously flowing current I, in particular short-circuit current I K , to a normal current I NORM exceeds a certain ratio. In one possible embodiment, the self-triggering circuit breaker 1 responds when the ratio between the short-circuit current I K and a normal current I NORM ≥ 20. This ratio can be designed differently depending on the particular geometry of the coils 12, 13 and the number of coil windings and the design of the switching or contact pad 10 for different applications.

Der erfindungsgemäße Stromunterbrecher 1 sowie die in Fig. 2 dargestellte Schaltvorrichtung 17 sind für verschiedenste Anwendungen einsetzbar, beispielsweise für Elektrofahrzeuge, Batterien sowie Photovoltaikanlagen. Bei einer möglichen Ausführungsform ist der Querschnitt der Spulenleiterbänder 4, 5 der beiden Spulen 12, 13 für Stromstärken von mehr als 100 Ampere ausgelegt. Die gewickelten Spulenleiterbänder 4, 5 der beiden Spulen 12, 13 sind voneinander elektrisch isoliert. Die durch die Spulen 12, 13 hindurchfließenden Ströme I erzeugen Magnetkräfte F, die unmittelbar auf die beweglichen Kontaktschenkel 8, 9 der Kontaktwippe wirken, sodass die Schaltgeschwindigkeit sehr hoch bzw. die Schaltdauer sehr gering ist. Die erfindungsgemäße Schaltvorrichtung 17 enthält eine Hybridschaltanordnung, die aus dem mechanischen Stromunterbrecher 1 und dem Halbleiterschalter 18 besteht. Diese Hybridschaltung schaltet einerseits besonders schnell und ist andererseits auch besonders robust gegenüber Umwelteinflüssen. Zudem hat die in der Schaltvorrichtung 17 vorgesehene Hybridschaltanordnung eine besonders hohe Lebensdauer und ermöglicht eine hohe Anzahl von Schaltzyklen bzw. Schaltvorgängen. Der erfindungsgemäße Stromunterbrecher 1 ist in relativ einfacher Weise mit geringem Aufwand herstellbar. Je nach Auslegung der Spulenleiterbänder 4, 5 und der Geometrie der beiden Spulen 12, 13 kann der Stromunterbrecher 1 auch für hohe Stromstärken von mehr als 100 Ampere, beispielsweise 400 oder sogar 800 Ampere, ausgelegt werden. Der selbstauslösende Stromunterbrecher 1 zeichnet sich durch eine sehr hohe Schaltgeschwindigkeit aus, wobei der Halbleiterschalter 18 ein Auftreten von Lichtbögen verhindert. Im normalen Dauerbetrieb ist der Stromunterbrecher 1 geschlossen. Da der Stromunterbrecher 1 bei normalem Dauerbetrieb einen sehr geringen Spannungsabfall aufweist, ist die Verlustleistung bei Verwendung der erfindungsgemäßen Schaltvorrichtung 17 im Normalbetrieb sehr gering. Bei der in Fig. 2 dargestellten Ausführungsform ist die Steuerschaltung 23 in der Schaltvorrichtung 17 integriert. Bei einer alternativen Ausführungsform kann der Halbleiterschalter 18 auch durch eine externe Steuerschaltung eines Geräts oder einer Anlage angesteuert werden.The circuit breaker 1 according to the invention and the in Fig. 2 shown switching device 17 can be used for a variety of applications, such as electric vehicles, Batteries and photovoltaic systems. In one possible embodiment, the cross section of the coil conductors 4, 5 of the two coils 12, 13 is designed for currents of more than 100 amperes. The wound coil conductors 4, 5 of the two coils 12, 13 are electrically insulated from each other. The currents I flowing through the coils 12, 13 generate magnetic forces F, which act directly on the movable contact legs 8, 9 of the contact rocker, so that the switching speed is very high or the switching duration is very low. The inventive switching device 17 includes a hybrid switching arrangement consisting of the mechanical circuit breaker 1 and the semiconductor switch 18. On the one hand, this hybrid circuit switches particularly quickly and, on the other hand, is also particularly robust against environmental influences. In addition, the hybrid switching arrangement provided in the switching device 17 has a particularly long service life and allows a large number of switching cycles or switching operations. The circuit breaker 1 according to the invention can be produced in a relatively simple manner with little effort. Depending on the design of the coil conductor strips 4, 5 and the geometry of the two coils 12, 13, the circuit breaker 1 can also be designed for high currents of more than 100 amperes, for example 400 or even 800 amps. The self-triggering circuit breaker 1 is characterized by a very high switching speed, wherein the semiconductor switch 18 prevents the occurrence of arcing. In normal continuous operation, the circuit breaker 1 is closed. Since the circuit breaker 1 has a very low voltage drop during normal continuous operation, the power loss when using the switching device 17 according to the invention in normal operation is very low. At the in Fig. 2 illustrated embodiment, the control circuit 23 is integrated in the switching device 17. In an alternative embodiment, the semiconductor switch 18 may also be controlled by an external control circuit of a device or a system.
