Description

Die Erfindung betrifft ein Schaltschütz, insbesondere Kondensatorschütz, welches einen Schutzschalter mit Hauptkontakten und mit einer Hauptschaltbrücke zum Öffnen und Schließen der Hauptkontakte, wobei die Hauptschaltbrücke zwischen einer Aus-Stellung, in der die Hauptkontakte geöffnet sind, und einer Ein-Stellung, in der die Hauptkontakte geschlossen sind, verstellbar ist, umfasst. Ferner umfasst das Schaltschütz einen Hilfsschalter mit Hilfskontakten und mit einer Hilfsschaltbrücke zum Öffnen und Schließen der Hilfskontakte, wobei die Hilfsschaltbrücke zwischen einer Aus-Stellung, in der die Hilfskontakte geöffnet sind, und einer Ein-Stellung, in der die Hilfskontakte geschlossen sind, verstellbar ist.The invention relates to a contactor, in particular capacitor contactor, which comprises a circuit breaker with main contacts and a main switching bridge for opening and closing the main contacts, the main switching bridge between an off position, in which the main contacts are open, and an on position, in which the Main contacts are closed, adjustable, includes. Furthermore, the contactor comprises an auxiliary switch with auxiliary contacts and with an auxiliary switching bridge for opening and closing the auxiliary contacts, wherein the auxiliary switching bridge between an off position, in which the auxiliary contacts are open, and an on position, in which the auxiliary contacts are closed, is adjustable ,

Ein solches Schaltschütz ist aus der DE 10 2004 018 252 B3 bekannt. Bei der dort beschriebenen Ausführung ist der Hilfsschalter fest mit dem Schaltschütz verbunden und entsprechend an das Schaltschütz angepasst. Ferner wird das Schaltschütz manuell über einen Betätigungsschieber betätigt, der nacheinander zunächst den Hilfsschalter und danach den Schutzschalter betätigt.Such a contactor is from the DE 10 2004 018 252 B3 known. In the embodiment described therein, the auxiliary switch is firmly connected to the contactor and adapted accordingly to the contactor. Furthermore, the contactor is operated manually via an actuating slide, which operates sequentially first the auxiliary switch and then the circuit breaker.

Bekannt sind ferner Hilfsschalter, die bei Bedarf lösbar auf einen Schutzschalter befestigt werden können. Die Hilfsschalter weisen Hilfsschaltbrücken auf, die derart mit der Hauptschaltbrücke des Schutzschalters lösbar verbunden werden können, dass durch Verstellen der Hauptschaltbrücke von ihrer Aus-Stellung in ihre Ein-Stellung die Hilfsschaltbrücke in ihre Ein-Stellung überführt wird. Dadurch lassen sich Schutzschalter bei Bedarf mit Hilfsschalter nachrüsten. Soll hierbei ein Voreilen des Schlie-ßens der Hilfskontakte des Hilfsschalters erzielt werden, müssen spezielle an den Anwendungsfall angepasste voreilende Hilfsschalter verwendet werden. Insbesondere bei Kondensatorschützen müssen demnach speziell angepasste Hilfsschalter verwendet werden. Beim Einschaltvorgang eines Schalters vor einem Kondensator ist ein sehr hoher temporärer Stormanstieg zu verzeichnen. Um diesen zu verringern, werden spezielle Kondensatorschütze mit voreilenden Hilfsschalter verwendet, wobei zeitlich vor den Hauptkontakten Hilfskontakte geschlossen werden. Die Hilfskontakte verbinden die Stromquelle über Widerstände mit dem Kondensator, so dass zunächst ein verringerter Stormanstieg zu verzeichnen ist. Daraufhin werden die Hauptkontakte ohne zwischengeschaltete Widerstände zeitlich verzögert, also wenn der Kondensator bereits teilweise aufgeladen ist, geschlossen. Der Stromanstieg beim Einschaltvorgang ist somit deutlich reduziert. Um eine ausreichende Reduktion des Stromanstiegs zu erzielen, müssen jedoch Hilfsschalter mit besonders großer Voreilung verwendet werden.Also known are auxiliary switches that can be releasably attached to a circuit breaker if necessary. The auxiliary switches have auxiliary switching bridges, which can be detachably connected to the main switching bridge of the circuit breaker in such a way that the auxiliary switching bridge is moved into its on position by adjusting the main switching bridge from its off position to its on position. As a result, circuit breakers can be retrofitted with auxiliary switches if required. If in this case it is intended to advance the closing of the auxiliary contacts of the auxiliary switch, then special auxiliary switches adapted to the application must be used. Especially with capacitor contactors therefore specially adapted auxiliary switches must be used. When a switch is switched on in front of a capacitor, a very high temporary rise in the current is recorded. To reduce this, special capacitor contactors with leading auxiliary switches are used, whereby temporally before the main contacts auxiliary contacts are closed. The auxiliary contacts connect the current source via resistors to the capacitor, so that initially a reduced rise in current is recorded. Thereafter, the main contacts without intervening resistors delayed in time, so when the capacitor is already partially charged, closed. The current increase during switch-on is thus significantly reduced. In order to achieve a sufficient reduction of the current increase, however, auxiliary switches with a particularly large overfeed must be used.

Aufgabe der vorliegenden Erfindung ist es, ein Schaltschütz mit Schutzschalter und Hilfsschalter bereitzustellen, bei dem ein herkömmlicher nicht speziell für Kondensatorschütze ausgebildeter Hilfsschalter verwendet werden kann, um eine ausreichende Voreilung der Hilfskontakte des Hilfsschalters zu erzielen.Object of the present invention is to provide a contactor with a circuit breaker and auxiliary switch, in which a conventional not specially trained for capacitor contactors auxiliary switch can be used to achieve a sufficient lead of the auxiliary contacts of the auxiliary switch.

Die Aufgabe wird erfindungsgemäß durch ein Schaltschütz, insbesondere Kondensatorschütz, umfassend
einen Schutzschalter mit Hauptkontakten und mit einer Hauptschaltbrücke zum Öffnen und Schließen der Hauptkontakte, wobei die Hauptschaltbrücke zwischen einer Aus-Stellung, in der die Hauptkontakte geöffnet sind, und einer Ein-Stellung, in der die Hauptkontakte geschlossen sind, verstellbar ist,
einen Hilfsschalter mit Hilfskontakten und mit einer Hilfsschaltbrücke zum Öffnen und Schließen der Hilfskontakte, wobei die Hilfsschaltbrücke zwischen einer Aus-Stellung, in der die Hilfskontakte geöffnet sind, und einer Ein-Stellung, in der die Hilfskontakte geschlossen sind, verstellbar ist,
ein Zwischenelement, das zwischen einer Betätigungsfläche der Hauptschaltbrücke und einer Haltefläche der Hilfsschaltbrücke abgestützt ist, wobei die Hilfsschaltbrücke in der Aus-Stellung der Hauptschaltbrücke in einer zwischen der Aus-Stellung und der Ein-Stellung liegenden Zwischenstellung, in der die Hilfskontakte geöffnet sind, gehalten ist und wobei durch Verstellen der Hauptschaltbrücke von ihrer Aus-Stellung in ihre Ein-Stellung die Hilfsschaltbrücke in ihre Ein-Stellung überführt wird, gelöst.The object is achieved by a contactor, in particular capacitor contactor, comprising
a circuit breaker with main contacts and with a main switching bridge for opening and closing the main contacts, wherein the main switching bridge between an off position, in which the main contacts are opened, and an on position, in which the main contacts are closed, is adjustable,
an auxiliary switch having auxiliary contacts and an auxiliary switching bridge for opening and closing the auxiliary contacts, the auxiliary switching bridge being adjustable between an off position in which the auxiliary contacts are open and an on position in which the auxiliary contacts are closed;
an intermediate element which is supported between an actuating surface of the main switching bridge and a holding surface of the auxiliary switching bridge, the auxiliary switching bridge being held in the off position of the main switching bridge in an intermediate position lying between the off position and the on position in which the auxiliary contacts are opened and is achieved by adjusting the main switching bridge from its off position to its on position, the auxiliary switching bridge in its on position, solved.

Bei diesem Schaltschütz kann ein herkömmlicher nicht-voreilender oder geringfügig voreilender Hilfsschalter verwendet werden, der nicht speziell für die Verwendung in einem Kondensatorschütz konstruiert ist. Dadurch, dass ein Zwischenelement zwischen der Hauptschaltbrücke und der Hilfsschaltbrücke vorgesehen ist, befindet sich die Hilfsschaltbrücke in der Aus-Stellung der Hauptschaltbrücke nicht in ihrer konstruktiv vorgegebenen Aus-Stellung, sondern ist bereits in Richtung zur Ein-Stellung vorgezogen. Sie befindet sich in einer Zwischenstellung zwischen der konstruktiv vorgegebenen Aus-Stellung und ihrer Ein-Stellung, wobei die Hilfskontakte noch nicht geschlossen sind. Der Verstellweg von der Zwischenstellung zur Ein-Stellung ist geringer als der Verstellweg von der Aus-Stellung zur Ein-Stellung. Somit werden beim Überführen der Hauptschaltbrücke von der Aus-Stellung in die Ein-Stellung die Hilfskontakte früher geschlossen als bei einer Verwendung ohne Zwischenelement. Es können demnach entweder nicht-voreilende oder geringfügig voreilende Hilfsschalter, die normalerweise nicht für Kondensatorschütze ausreichend wären, verwendet werde. Hierdurch müssen nicht speziell für Kondensatorschütze konstruierte Hilfsschalter verwendet werden.In this contactor can be a conventional non-leading or slightly leading auxiliary switch not specifically designed for use in a capacitor contactor. Because an intermediate element is provided between the main switching bridge and the auxiliary switching bridge, the auxiliary switching bridge is not in the off position of the main switching bridge in its structurally predetermined off position, but is already preferred in the direction of the on position. It is located in an intermediate position between the structurally predetermined off position and its on position, wherein the auxiliary contacts are not yet closed. The adjustment path from the intermediate position to the on position is less than the adjustment path from the off position to the on position. Thus, when transferring the main switching bridge from the off position to the on position, the auxiliary contacts are closed earlier than when used without an intermediate element. Accordingly, either non-leading or slightly leading auxiliary switches, which would normally not be sufficient for capacitor contactors, may be used. As a result, not specially designed for capacitor contactors auxiliary switch must be used.

Durch die Verwendung des Zwischenelements werden die Betätigungsfläche und die Haltefläche in der Aus-Stellung der Hauptschaltbrücke beabstandet zueinander gehalten.By the use of the intermediate element, the actuating surface and the holding surface in the off position of the main switching bridge are kept spaced from each other.

Besonders vorteilhaft ist es, wenn das Zwischenelement in Form eines Federelements gestaltet ist. Somit erlaubt bereits das Zwischenelement eine Ausgleichsbewegung zwischen der Hauptschaltbrücke und der Hilfsschaltbrücke zu dem Zeitpunkt, wenn die Hilfsschaltbrücke bereits ihre Ein-Stellung erreicht hat und die Hauptschaltbrücke noch einen Verstellweg bis zum Erreichen ihrer Ein-Stellung vollziehen muss. Dabei wird das Zwischenelement beim weiteren Verstellen der Hauptschaltbrücke ausgehend von der Stellung, in der die Hilfsschaltbrücke bereits ihre Ein-Stellung erreicht hat, bis zur Ein-Stellung komprimiert. Es müssen daher keine separaten Ausgleichsmittel vorgesehen werden.
Das Zwischenelement kann eine Befestigungsabschnitt, mit dem es fest mit einer der Schaltbrücken verbunden ist, und zumindest einen Federarm, mit dem es federn gegen die andere Schaltbrücke abgestützt ist, aufweisen. Insbesondere, wenn das Zwischenelement aus Blech gefertigt ist, nimmt es im komprimierten Zustand eine sehr geringe Höhe ein. Somit ist aufgrund von Fertigungstoleranzen und eines üblich vorgesehenen Spiels zwischen der Hauptschaltbrücke und der Hilfsschaltbrücke kein weiteres Ausgleichselement erforderlich.It is particularly advantageous if the intermediate element is designed in the form of a spring element. Thus, even the intermediate element allows a compensating movement between the main switching bridge and the auxiliary switching bridge at the time when the auxiliary switching bridge has already reached its on position and the main switching bridge still has to perform an adjustment to reach their on position. In this case, the intermediate element is compressed on further adjustment of the main switching bridge starting from the position in which the auxiliary switching bridge has already reached its on position to the on position. Therefore, no separate compensation means must be provided.
The intermediate element may have a fastening portion, with which it is fixedly connected to one of the switching bridges, and at least one spring arm with which it is supported against the other switching bridge springs. In particular, when the intermediate element is made of sheet metal, it takes a very compressed state low altitude. Thus, no further compensation element is required due to manufacturing tolerances and a customary game between the main switching bridge and the auxiliary switching bridge.

Grundsätzliche ist es sowohl möglich, dass das Zwischenelement fest mit der Hauptschaltbrücke fest verbunden ist, als auch dass es mit der Hilfsschaltbrücke fest verbunden ist.In principle, it is both possible that the intermediate element is firmly connected to the main switching bridge, as well as that it is firmly connected to the auxiliary switching bridge.

Der Mitnehmer 24 weist einen entlang der Stellachse X verlaufenden Basissteg 25 und an dem Ende des Basisstegs 25 einen ersten Mitnehmervorsprung 26 und einen von diesem abgewandten zweiten Mitnehmervorsprung 27 auf. Der erste Mitnehmervorsprung 26 bildet eine erste Betätigungsfläche 28 und der zweite Mitnehmervorsprung 27 bildet eine zweite Betätigungsfläche 29. Der Mitnehmer 24 ist somit im Schnitt betrachtet T-förmig. An dem Basissteg 25 ist das Zwischenelement 5 befestigt und stützt sich gegen die Betätigungsflächen 28, 29 ab. FIG. 2 shows the main switching bridge 2 in a perspective view. The driver 24 has a base web 25 running along the control axis X and a first driver projection 26 and a second driver projection 27 remote from the base web 25 at the end of the base web 25. The first driver projection 26 forms a first actuating surface 28 and the second driver projection 27 forms a second actuating surface 29. The driver 24 is thus viewed in section T-shaped. At the base web 25, the intermediate element 5 is fixed and is supported against the actuating surfaces 28, 29 from.

Figur 3 zeigt die Verbindung zwischen der Hauptschaltbrücke 2 und einer Hilfsschaltbrücke 30. Die Hilfsschaltbrücke 30 weist zwei zur Hauptschaltbrücke 2 weisende Haltearme 31, 32, nämlich einen ersten Haltearm 31 und einen zweiten Haltearm 32, auf. An dem ersten Haltearm 31 ist ein erster Haltevorsprung 33 und an dem zweiten Haltearm 32 ein zweiter Haltevorsprung 34 vorgesehen, die sich gegenüberliegend angeordnet sind. Der erste Haltevorsprung 33 bildet eine erste Haltefläche 35, die mittelbar über das Zwischenelement 5, wie nachfolgend noch beschrieben wird, gegen die erste Betätigungsfläche 28 abgestützt ist. Der zweite Haltevorsprung 34 bildet eine zweite Haltefläche 36, die mittelbar über das Zwischenelement 5 gegen die zweite Betätigungsfläche 29 abgestützt ist. FIG. 3 shows the connection between the main switching bridge 2 and an auxiliary switching bridge 30. The auxiliary switching bridge 30 has two to the main switching bridge 2 facing holding arms 31, 32, namely a first arm 31 and a second arm 32, on. On the first holding arm 31, a first holding projection 33 and on the second holding arm 32, a second holding projection 34 are provided, which are arranged opposite one another. The first holding projection 33 forms a first holding surface 35, which is indirectly supported via the intermediate element 5, as will be described below, against the first actuating surface 28. The second holding projection 34 forms a second holding surface 36, which is indirectly supported via the intermediate element 5 against the second actuating surface 29.

Figur 4 zeigt das Zwischenelement 5 in perspektivischer Darstellung. Das Zwischenelement 5 ist als Federelement aus Blech, vorzugsweise aus Federstahl, gestaltet. Es umfasst einen Befestigungsabschnitt 37, mit dem es am Mitnehmer der Hauptschaltbrücke befestigt wird. Ferner umfasst es einen ersten Federarm 38 und einen zweiten Federarm 39, die zusammen mit dem Befestigungsabschnitt 37 in einer Richtung von einem Basisabschnitt 40 des Zwischenelements 5 vorstehen. Die beiden Federarme 38, 39 sind beidseitig des Basisabschnitts 40 angeordnet. Der Befestigungsabschnitt 37 und der Basisabschnitt 40 bilden eine Hauptebene, von der sich die Federarme 38, 39 ausgehend vom Basisabschnitt 40 zu freien Enden 52, 53 der Federarme 38, 39 kontinuierlich entfernen. FIG. 4 shows the intermediate element 5 in a perspective view. The intermediate element 5 is designed as a spring element made of sheet metal, preferably spring steel. It comprises a fastening portion 37, with which it is fastened to the driver of the main switching bridge. Further, it includes a first spring arm 38 and a second spring arm 39 which, together with the attachment portion 37, project in a direction from a base portion 40 of the intermediate member 5. The two spring arms 38, 39 are arranged on both sides of the base portion 40. The attachment section 37 and the base portion 40 form a main plane from which the spring arms 38, 39, starting from the base portion 40 to free ends 52, 53 of the spring arms 38, 39 continuously remove.

Anhand der Figur 5 soll erläutert werden, wie das Zwischenelement 5 an dem Mitnehmer 24 befestigt ist. Figur 5 zeigt hierfür einen Schnitt entlang der Schnittlinie V-V gemäß Figur 3. Der Basissteg 25 weist zwei Seitenwände 41, 42 auf, die beabstandet zueinander angeordnet sind und mit einem Verbindungssteg 43 miteinander verbunden sind. In dem Verbindungssteg 43 ist ein Befestigungsdurchbruch 44 vorgesehen, in den der Befestigungsabschnitt 40 des Zwischenelements 5 hindurch gesteckt ist. Der Befestigungsabschnitt 40 weist einen Schlitz 45 auf, so dass zwei elastisch federnde Rastarme 46, 47 gebildet sind. Die Rastarme 46, 47 weisen voneinander weg gerichtete Rastvorsprünge 48, 49 mit Rastflächen 50, 51 auf. Das Zwischenelement 5 kann mit dem Befestigungsabschnitt 25 in Einschubrichtung S in den Befestigungsdurchbruch 44 gesteckt werden, wobei die Breite des Befestigungsdurchbruchs 44 der Breite des Befestigungsabschnitts 25 entspricht. Wenn die Rastvorsprünge 48, 49 den Verbindungssteg 43 passieren, werden die Rastarme 46, 47 zueinander elastisch verformt. Im vollständig eingesteckten Zustand haben die Rastvorsprünge 48, 49 den Verbindungssteg 43 vollständig passiert, so dass die Rastarme 46, 47 wieder ihre ursprüngliche Position einnehmen und die Rastflächen 50, 51 gegen den Verbindungssteg 43 abgestützt sind. Somit ist das Zwischenelement 5 gegen Herausziehen gesichert.Based on FIG. 5 should be explained how the intermediate element 5 is fixed to the driver 24. FIG. 5 shows for this purpose a section along the section line VV according to FIG. 3 , The base web 25 has two side walls 41, 42, which are arranged at a distance from one another and are connected to one another by a connecting web 43. In the connecting web 43, a fastening opening 44 is provided, into which the fastening portion 40 of the intermediate element 5 is inserted. The attachment portion 40 has a slot 45, so that two elastically resilient latching arms 46, 47 are formed. The latching arms 46, 47 have latching projections 48, 49 directed away from one another with latching surfaces 50, 51. The intermediate element 5 can be inserted into the fastening opening 44 with the fastening section 25 in the insertion direction S, wherein the width of the fastening opening 44 corresponds to the width of the fastening section 25. When the latching projections 48, 49 pass through the connecting web 43, the latching arms 46, 47 are elastically deformed relative to one another. In the completely inserted state, the latching projections 48, 49 have completely passed the connecting web 43, so that the latching arms 46, 47 again assume their original position and the latching surfaces 50, 51 are supported against the connecting web 43. Thus, the intermediate element 5 is secured against pulling out.

Aus Figur 6, welche einen Schnitt entlang der Schnittlinie VI-VI gemäß Figur 3 zeigt, ist ersichtlich, wie sich die Federarme 38 gegen die Halteflächen 36 abstützen. In Figur 6 ist die Hauptschaltbrücke 2 in der Aus-Stellung gezeigt. Durch die Federarme 38 werden die Betätigungsflächen 29 und die Halteflächen 36 beabstandet zueinander gehalten. Hierbei wird die Hilfsschaltbrücke 30 in einer Zwischenstellung zwischen ihrer Aus-Stellung und ihrer Ein-Stellung mit Vorspannung der Federarme 38 gehalten. Wenn die Hauptschaltbrücke 2 in Richtung zu ihrer Ein-Stellung verstellt wird, wird zunächst bis zu einer Zwischenstellung der Hauptschaltbrücke 2 die Hilfsschaltbrücke 30 in ihre Ein-Stellung überführt. In diesen Stellungen der Hauptschaltbrücke 2 und der Hilfsschaltbrücke 30 ist das Zwischenelement 5 wie in Figur 6 gezeigt angeordnet und hält die Betätigungsflächen 29 und die Halteflächen 36 auf Abstand. Beim weiteren Verstellen der Hauptschaltbrücke 2 in ihre Ein-Stellung bewegt sich die Hilfsschaltbrücke 30 nicht mehr, so dass eine Ausgleichsbewegung zwischen der Hauptschaltbrücke 2 und der Hilfsschaltbrücke 30 erfolgen muss. Dies wird dadurch erzielt, dass das Zwischenelement 5 komprimiert wird. Die Federarme 38 werden elastisch verformt, bis sie in der Ebene des Basisabschnitts 40 und des Befestigungsabschnitts 37 liegen. Da die Federarme 38 an ihren freien Enden 52 in Richtung zur Ebene des Basisabschnitts 40 und des Befestigungsabschnitts 37 gebogen sind, weist der Mitnehmer 24 eine Ausnehmung 54 auf, in die die freien Enden 52 eintauchen können.Out FIG. 6 , which is a section along the section line VI-VI according to FIG. 3 shows, it can be seen how the spring arms 38 are supported against the support surfaces 36. In FIG. 6 the main switching bridge 2 is shown in the off position. By the spring arms 38, the actuating surfaces 29 and the holding surfaces 36 are spaced from each other. Here, the auxiliary switching bridge 30 is held in an intermediate position between its off position and its on position with bias of the spring arms 38. When the main switching bridge 2 is adjusted in the direction of its on position, the auxiliary switching bridge 30 is first transferred to its on position up to an intermediate position of the main switching bridge 2. In these positions of the main switching bridge 2 and the auxiliary switching bridge 30, the intermediate element 5 is as in FIG. 6 shown arranged and holds the actuating surfaces 29 and the support surfaces 36 at a distance. Upon further adjustment of the main switching bridge 2 in its on position, the auxiliary switching bridge 30 no longer moves, so that a compensating movement between the main switching bridge 2 and the auxiliary switching bridge 30 must be made. This is achieved by compressing the intermediate element 5. The spring arms 38 are elastically deformed until they lie in the plane of the base portion 40 and the attachment portion 37. Since the spring arms 38 are bent at their free ends 52 in the direction of the plane of the base portion 40 and the mounting portion 37, the driver 24 has a recess 54 into which the free ends 52 can dip.
