Description

Die Erfindung bezieht sich auf ein Schaltgerät mit einem Schaltschloß, das einen Schalthebel, eine Klinke und einen Klinkenhebel als Gegenlager für die Klinke aufweist, die sich bei Auslösung um ihre Lagerachse dreht und den Schalthebel zur Betätigung von Kontakten freigibt, und mit einer mit dem Schaltschloß in Wirkverbindung stehenden Handhabe.The invention relates to a switching device with a Switch lock that has a gear lever, a pawl and one Pawl lever as a counter bearing for the pawl, which is when triggered rotates around its bearing axis and the gear lever releases for the actuation of contacts, and with one with the Switch lock in operatively connected handle.

Ein gattungsgemäßes Schaltgerät wird von mehreren Elektrounternehmen vertrieben.A generic switchgear is used by several electrical companies expelled.

FIG 4 zeigt ein Schaltschloß 1 eines Leistungsschalters in EIN-Stellung. Das Schaltschloß 1 ist in dieser Stellung im verklinkten Zustand, in dem die Hauptkontakte des Leistungsschalters von denen hier lediglich ein Hauptkontakt 3 dargestellt ist, geschlossen sind. Erst bei Auslösung des Schaltschlosses 1 wirkt ein Schalthebel 2 auf einen Schieber und eine daran angekoppelte Wippe, durch die die Hauptkontakte 3 geöffnet werden. Zugleich wirkt die Schaltwelle 2 auf einen Kontaktbrückenträger 4 eines angekoppelten Hilfsschalters HS. Das Schaltschloß 1 ist im wesentlichen aus einem Hebelsystem mit einer Handhabe 5, einer Klinke 6 und einem Entklinkungshebel 7 zusammengesetzt. Die hier dargestellte EIN-Stellung wird ursächlich durch die Position der Handhabe 5 erreicht. Über eine mit der Handhabe 5 verbundene Stange 8 ist die Klinke 6 kulissengeführt in ihrer Stellung veränderbar. Sie wirkt auf die Stellung des Schalthebels 2 ein, der den oben beschriebenen Schaltzustand von Haupt- 3 und Hilfskontakten 9 bestimmt. Das durch eine Feder 10 bewirkte Drehmoment verstellt die Schaltwelle 2 nach Umlegen der Handhabe 5 in die AUS-Stellung derart, daß der Hauptkontakt geöffnet wird und die Einwirkung auf den Kontaktbrückenträger 4 des Hilfsschalters HS aufgehoben wird. Die Stange 8 bildet zusammen mit der Handhabe 5 ein Kniegelenk. Die Handhabe 5 ist ein fest gelagerter Hebel, der z.B. als Kipphebel oder Wippe ausgeführt sein kann.4 shows a switch lock 1 of a circuit breaker in Attitude. The switch lock 1 is in this position in the latched state in which the main contacts of the circuit breaker only one main contact 3 is shown here is closed. Only when the key switch is triggered 1 acts a shift lever 2 on a slide and a rocker connected to it, through which the main contacts 3 be opened. At the same time, the control shaft 2 acts on one Contact bridge carrier 4 of a coupled auxiliary switch HS. The switch lock 1 is essentially a lever system with a handle 5, a pawl 6 and a release lever 7 composed. The ON position shown here is caused by the position of the handle 5. About a connected to the handle 5 rod 8 is the The position of jack 6 can be changed in a guided manner. she acts on the position of the shift lever 2, the above Switching state of main 3 and auxiliary contacts 9 described certainly. The torque caused by a spring 10 is adjusted the control shaft 2 after moving the handle 5 in the OFF position so that the main contact is opened and the action on the contact bridge support 4 of the auxiliary switch HS is canceled. The rod 8 forms together with the Handle 5 a knee joint. The handle 5 is a fixed one Lever which e.g. designed as a rocker arm or rocker can be.

Bei einem solchen, mit einem Drehantrieb ausgeführten Leistungsschalter soll der Betreiber erkennen können, wenn das Schaltschloß durch den Überstromauslöser oder den Spannungsauslöser ausgelöst wird. Dies soll, wie in den FIG 5, 6 und 7 dargestellt, dadurch kenntlich gemacht werden, daß die Handhabe im ausgelösten Zustand in einer Zwischenstellung zwischen den Stellungen EIN und AUS stehen bleibt. Diese als Tripped-Stellung bezeichnete Zwischenstellung ist der FIG 6 zu entnehmen, während die Stellungen AUS bzw. EIN in den FIG 5 bzw. 7 abgebildet sind.In such a circuit breaker designed with a rotary actuator the operator should be able to recognize if that Switch lock through the overcurrent release or the voltage release is triggered. This should, as in FIGS. 5, 6 and 7 represented, identified by the fact that the handle in the released state in an intermediate position between remains in the ON and OFF positions. This as The intermediate position referred to as the tripped position is shown in FIG. 6 can be seen while the positions OFF and ON in FIG 5 and 7 are shown.

Eine bereits bekannte Ausführung einer Tripped-Stellung ist prinzipiell in den FIG 8, 9 und 10 wiedergegeben. Die Lösung ist hier mit Hilfe von zwei Druckfedern, einem Schieber und einem Hebel realisiert. Die beim Auslösen durchschwingende, hier nicht dargestellte Klinke, betätigt den mit einer Druckfeder vorgespannten Hebel, der einen mit einer weiteren Druckfeder vorgespannten Schieber entklinkt. Der Schieber rutscht nach vorn und blockiert damit das Zurückdrehen des zum Drehantrieb gehörenden Gegenrads. Die Druckfeder des Schiebers wirkt also der Drehfeder in der Zahnwippe entgegen und verhindert somit das Zurückdrehen. Beim Zurücksetzen in die Stellung AUS mittels der Handhabe wird der Schieber zurückgeschoben und die dahinterliegende Druckfeder wieder gespannt. Gleichzeitig verklinkt die hier nicht dargestellte Klinke am Klinkenhebel und der Schalter kann wieder eingeschaltet werden.An already known version of a tripped position is shown in principle in FIGS. 8, 9 and 10. The solution is here with the help of two compression springs, a slide and realized a lever. The swinging when triggered, Jack not shown here, actuates the with a compression spring preloaded lever, one with another Pressure spring preloaded slide unlatched. The slider slides forward and blocks the turning back of the counter wheel belonging to the rotary drive. The compression spring of the Slider thus counteracts the torsion spring in the rocker and thus prevents turning back. When resetting in the OFF position is pushed back by the handle and the compression spring behind it tensioned again. At the same time, the one not shown here latches Pawl on the pawl lever and the switch can be switched on again become.

Die DE 92 06 137 U1 offenbart einen Leistungsschalter mit einem Schaltschloß, der der einleitend genannten Gattung entspricht. Das Schaltschloß weist hier ebenfalls einen Schalthebel, eine Klinke und einen Klinkenhebel als Gegenlager für die Klinke auf, die sich bei Auslösung um ihre Lagerachse dreht und den Schalthebel zur Betätigung von Kontakten freigibt. Die Handhabe des Leistungsschalters steht mit dem Schaltschloß in Wirkverbindung. Eine Tripped Stellung, durch die dem Betreiber die Auslösung des Schaltschlosses angezeigt wird, ist der DE 92 06 137 U1 allerdings nicht entnehmbar.DE 92 06 137 U1 discloses a circuit breaker with a Switch lock that corresponds to the type mentioned in the introduction. The key switch also has a gear lever here, a pawl and a pawl lever as a counter bearing for the pawl, which is triggered around its bearing axis rotates and releases the switch lever for actuating contacts. The circuit breaker is in contact with the Key switch in operative connection. A tripped position, through which indicates to the operator that the key switch has been triggered is, however, the DE 92 06 137 U1 is not removable.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Schaltgerät der obengenannten Art auf einfache Weise, d.h. mit geringem Kosten- und Teileaufwand eine Tripped-Stellung zu realisieren.The invention has for its object in a switching device of the above type in a simple manner, i.e. with little Realizing a tripped position in terms of costs and parts.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß im Schaltschloß eine Sperre angeordnet ist, die bei Auslösung das Durchschwingen der ausgelösten Klinke zuläßt, aber das Zurückschwingen der Klinke behindert und die Klinke in einer bestimmten Stellung festhält, in der die Handhabe aufgrund der Wirkverbindung in einer Zwischenstellung zwischen der EIN- und AUS-Stellung des Schaltgeräts gehalten wird. Der Betreiber des Schaltgeräts kann somit erkennen, ob eine Auslösung vorliegt.According to the invention the object is achieved in that Switch lock is arranged a lock when triggered allows the triggered jack to swing through, but that Swinging back of the pawl hinders and the pawl in one holds certain position in which the handle due the operative connection in an intermediate position between the ON and OFF position of the switching device is held. The operator of the switching device can thus recognize whether a trip is present.

Vorteilhafte Weiterbildung der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention are the subclaims refer to.

Gemäß Anspruch 2 ist es vorteilhaft, wenn nach Auslösung die Handhabe in Richtung AUS betätigt werden muß, wobei die Klinke aufgrund der Wirkverbindung am Sperrenkopf der Sperre vorbeigezogen und am Klinkenhebel verklinkt wird, bevor das Schaltgerät die Stellung EIN einnimmt.According to claim 2, it is advantageous if after triggering the Handle must be pressed in the OFF direction, the Pawl due to the active connection on the lock head of the lock pulled past and latched on the ratchet lever before that Switching device assumes the ON position.

Weiterhin ist es vorteilhaft, wenn die Sperre als Federarm mit dem Sperrenkopf ausgeführt ist, der derart einerseits mit Gleitflächen und andererseits mit Sperrflächen versehen ist, daß die Klinke beim Durchschwingen an den Gleitflächen entlanggleitet und beim Zurückschwingen von den Sperrflächen festgehalten wird.It is also advantageous if the lock as a spring arm is designed with the locking head, the one hand with Sliding surfaces and on the other hand is provided with locking surfaces, that the pawl slides along the sliding surfaces as it swings and when swinging back from the restricted areas is held.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:

FIG 1
ein Schaltschloß in EIN-Stellung,
FIG 2
ein Schaltschloß in Tripped-Stellung und
FIG 3
eine im Schaltschloß realisierte Sperre in Verbindung mit einer Klinke.
An embodiment of the invention is explained below with reference to a drawing. Show it:
FIG. 1
a key switch in the ON position,
FIG 2
a key switch in the tripped position and
FIG 3
a lock realized in the switch lock in connection with a latch.

FIG 1 zeigt ein Schaltschloß 1 eines Schaltgeräts mit Drehantrieb. Von dem Drehantrieb ist hier lediglich ein Gegenrad 2 dargestellt, das in Verbindung mit einem U-Bügel 3 ein Kniegelenk bildet. Das Kniegelenk ist in einer Kulisse 4 in einer Schaltplatine 5 geführt. Weitere an der Schaltplatine 5 befestigte Komponenten des Schaltschlosses 1 sind ein Klinkenhebel 6, eine Klinke 7, ein Schalthebel 8, eine Ausschaltfeder 9 und eine Sperre 10. Das hier gezeigte Schaltschloß 1 befindet sich in der EIN-Stellung, in der die Klinke 7 an dem als Gegenlager wirkenden Klinkenhebel 6 verklinkt ist und die an der Schaltwelle 8 angreifende Ausschaltfeder 9 durch den Drehantrieb, d.h. über das Gegenrad 2, vorgespannt ist. Wird der Klinkenhebel 6 bei einer Auslösung betätigt, dreht er sich um seine Lagerachse. Dabei rutscht die Klinke 7 vom Klinkenhebel 6 ab und beschreibt unter dem Klinkenhebel 6 eine Drehbewegung um ihre durch den Schenkel des U-Bügels 3 gebildete Lagerachse 17. Die unter dem Klinkenhebel 6 angeordnete Sperre 10 weist einen Sperrenkopf 11 auf, der derart einerseits mit Gleitflächen 12 und andererseits mit Sperrflächen 13 versehen ist, daß die Klinke 7 beim Durchschwingen an den Gleitflächen 12 entlanggleitet und beim Zurückschwingen von den Sperrflächen 13 festgehalten wird. Beim Durchschwingen der ausgelösten Klinke 7 gemäß der durch den Pfeil 14 angegebenen Richtung ist die Bewegung durch den Sperrenkopf 11 nahezu ungehindert. Das Zurückschwingen der Klinke 7 wird jedoch so stark behindert, daß die Klinke 7 in einer bestimmten Stellung vor dem Wiederverklinken festgehalten wird. Die Teilekette bis zur hier nicht dargestellten Handhabe über das Gegenrad 2 wird in ihrer Bewegung angehalten und kommt in der sogenannten "Tripped-Stellung" zwischen den Stellungen EIN und AUS gemäß FIG 2 zum Stehen. Außer den bereits beschriebenen Komponenten ist in FIG 2 zusätzlich die als Drehknopf 15 ausgebildete Handhabe des Drehantriebs eingezeichnet. Die Klinke 7 ist hier durch die Sperrfläche 13 am Sperrenkopf 11 gefangen.1 shows a switch lock 1 of a switching device with a rotary drive. There is only one counter wheel 2 of the rotary drive here shown that in connection with a U-bracket 3 a knee joint forms. The knee joint is in a backdrop 4 in one Circuit board 5 out. More attached to the circuit board 5 Components of the key switch 1 are a ratchet lever 6, a pawl 7, a shift lever 8, an opening spring 9 and a lock 10. The switch lock 1 shown here is located in the ON position, in which the pawl 7 on the as Counter bearing acting latch lever 6 is latched and on the switching shaft 8 attacking switch-off spring 9 by the Rotary drive, i.e. is biased via the counter gear 2. Becomes the pawl lever 6 actuates when triggered, it rotates around its bearing axis. The pawl 7 slips from Pawl lever 6 off and describes under the pawl lever 6 a rotary movement around her through the leg of the U-bracket 3 formed bearing axis 17. The arranged under the ratchet lever 6 Lock 10 has a locking head 11, which is such on the one hand with sliding surfaces 12 and on the other hand with locking surfaces 13 is provided that the pawl 7 when swinging through slides along the sliding surfaces 12 and when swinging back is held by the blocking surfaces 13. When swinging through the triggered pawl 7 according to the arrow 14 direction indicated is the movement through the lock head 11 almost unhindered. The swing back of the pawl 7 will however, so severely hampered that the pawl 7 in a certain Position is held before relinking. The Parts chain up to the handle, not shown here, over the Counter gear 2 is stopped in its movement and comes in the so-called "tripped position" between the positions ON and OFF according to FIG 2 for standing. Except for those already described The component in FIG. 2 is additionally that of a rotary knob 15 trained handle of the rotary actuator. The Pawl 7 is here through the locking surface 13 on the locking head 11 captured.

Wird der Drehknopf 15 in Richtung AUS gedreht, so wird die Klinke 7 aufgrund der über das Kniegelenk übertragenen Kraft zunächst am Sperrenkopf 11 und anschließend unter dem Klinkenhebel 6 vorbeigezogen, bis sie am Klinkenhebel 6 verklinkt. Erst nach dieser Verklinkung ist das Schaltgerät einschaltbar, wobei die Ausschaltfeder 9 (siehe FIG 1) vorgespannt wird und damit die zur Auslösung erforderliche Energie aufnimmt.If the rotary knob 15 is turned in the OFF direction, the Jack 7 due to the force transmitted through the knee joint first on the locking head 11 and then under the ratchet lever 6 passed until it latches on the ratchet lever 6. The switching device can only be switched on after this latching, the opening spring 9 (see FIG 1) biased and thus the energy required to trigger it records.

Der Drehknopf 15 darf aus der Tripped-Stellung nicht sofort in Richtung EIN gedreht werden, da in diesem Fall die Klinke 7 noch nicht verklinkt ist und somit das Gegenlager zur Vorspannung der Ausschaltfeder 9 fehlt. Das Schaltgerät wäre in diesem Fall nicht eingeschaltet.The rotary knob 15 must not move out of the tripped position immediately be turned towards ON because in this case the jack 7 is not yet latched and thus the counter bearing for preloading the switch-off spring 9 is missing. The switching device would be in not turned on in this case.

FIG 3 zeigt die Sperre 10 mit einem Federarm 16 und einem Sperrenkopf 11. Dieser weist optimierte Gleitflächen 12 und Sperrflächen 13 auf, die die ebenfalls dargestellte Klinke 7 einerseits beim Durchschwingen kaum behindern und beim Zurückschwingen festhalten. 3 shows the lock 10 with a spring arm 16 and a Locking head 11. This has optimized sliding surfaces 12 and Locking surfaces 13 on the pawl 7 also shown on the one hand hardly hinder when swinging and when Hold back swinging.

Obwohl die vorliegende Erfindung unter Bezugnahme auf die in der beigefügten Zeichnung dargestellte Ausführungsform erläutert ist, sollte berücksichtigt werden, daß damit nicht beabsichtigt ist, die Erfindung nur auf die dargestellte Ausführungsform zu beschränken, sondern alle möglichen Änderungen, Modifizierungen und äquivalente Anordnungen, soweit sie vom Inhalt der Patentansprüche gedeckt sind, einzuschließen.Although the present invention with reference to the in of the accompanying drawing illustrated embodiment is, it should be borne in mind that this is not intended is, the invention only to the illustrated embodiment to limit, but all possible changes, Modifications and equivalent arrangements insofar as they are from Contents of the claims are covered.
