Description
Die Erfindung betrifft eine Betätigungseinrichtung für einen Leistungsschalter mit einer Verklinkeinrichtung zur Freigabe einer ersten Schaltstellung des Leistungsschalters und deren Überführung in eine zweite Schaltstellung, wobei die Freigabe wahlweise mechanisch oder elektrisch steuerbar ist. Dokument US-A-3 236 967 bildet die Gattung ab.The invention relates to an actuating device for a Circuit breaker with a latching device for release a first switch position of the circuit breaker and their Transfer to a second switching position, the release is either mechanically or electrically controllable. Document US-A-3 236 967 represents the genus.
Bei derartigen Leistungsschaltern sind also zwei voneinander
verschiedene Freigaben der Verklinkung vorgesehen, wobei die
mechanische Freigabe der Verklinkung mit dem Einwirken eines
Drucktasters direkt auf die Verklinkeinrichtung einwirkt,
während bei der elektrischen Freigabe der Verklinkung mit
einem Tastschalter ein Befehlsstromkreis für einen Betätigungsmagneten
geschlossen wird, der seinerseits die Verklinkeinrichtung
im Sinne der Freigabe steuert.
Beide Möglichkeiten der Freigabe der Verklinkung sind für
diese Leistungsschalter generell vorgesehen und werden entsprechend
den Vorstellungen des Kunden im Bedarfsfall vor Ort
wirksam geschaltet.In such circuit breakers, two different releases of the latch are provided, the mechanical release of the latch acting directly on the latching device with the action of a pushbutton, while when the latch is electrically released, a command circuit for an actuating magnet is closed, which in turn controls the latching device in terms of the release.
Both options for releasing the latch are generally provided for these circuit breakers and are activated on site according to the customer's requirements if necessary.
Im einfachsten Fall werden für die jeweiligen Freigaben verschiedene
mechanische Betätigungsstangen mit den jeweils
notwendigen Führungsorganen - Drehlager, Führungsschienen,
Halterungen, etc. - benötigt.
Die der Erfindung zugrundeliegende Aufgabe besteht darin, die
Teilevielfalt zur Realisierung derartiger Freigaben der
Verklinkeinrichtungen für die Leistungsschalter auf ein
Minimum zu reduzieren, ohne jedoch dabei auf die Wahlfreiheit
zwischen einer elektrischen oder einer mechanischen Freigabe
der Verklinkung bei einer späteren Montage der Leistungsschalter
bei den Kunden vor Ort hinnehmen zu müssen. Erfindungsgemäß
wird dies durch die Merkmale
The object on which the invention is based is to reduce the number of parts for realizing such releases of the latching devices for the circuit breakers to a minimum, without, however, giving the customer the freedom to choose between an electrical or a mechanical release of the latching when the circuit breakers are later installed To take place. According to the invention, this is due to the features
Mit dem Vorsehen einer für beide Betätigungsarten des Leistungsschalters - der mechanischen Freigabe und der elektrischen Freigabe der Verklinkung - gleichen Betätigungsstange ist erreicht, daß der Aufwand zur Realisierung der Freigabe des Leistungsschalters sich dahingehend reduziert, daß lediglich mit einer bestimmten axialen Winkelstellung des Tastkopfes der Betätigungsstange die mechanische oder die elektrische Freigabe des Leistungsschalters wahlfrei steuerbar ist. Bei der mechanischen Freigabe erreicht lediglich der längere Teil mit dem kleiner dem halben Querschnittsmaß der Betätigungsstange abgestuften Tastkopf den Entriegelungshebel zur Freigabe der Verklinkeinrichtung. Wird die Winkelstellung der Betätigungsstange um 180° um die Längsachse derselben gedreht, so wird mit der Betätigung der Betätigungsstange in Druckrichtung der Entriegelungshebel der Verklinkeinrichtung durch den Tastkopf nicht mehr erreicht, so daß auch keine mechanische Freigabe der Verklinkung erfolgt. Der für beide Freigaben grundsätzlich über den Kipphebel betätigte Druckschalter wird im Falle der elektrischen Freigabe so eingesetzt, daß mit einem freischaltbaren Kontakt, beispielsweise einem Arbeitskontakt, ein Auslösemagnet steuerbar ist, der auf den Entriegelungshebel im Sinne der elektrischen Steuerung zur Freigabe der Verklinkung einwirkt. Im Falle der mechanischen Betätigung können die Kontakte beispielsweise für eine optische Meldung der mechanischen Betätigung verwendet werden.With the provision of one for both types of operation of the circuit breaker - mechanical release and electrical Release of the latch - same actuation rod is achieved that the effort to realize the release the circuit breaker is reduced in that only with a certain axial angular position of the Probe of the actuating rod, the mechanical or the electrical release of the circuit breaker can be controlled optionally is. With the mechanical release, only the longer part with the smaller half the cross-sectional dimension of the Actuating rod graduated probe the release lever to release the latching device. Will the angular position the operating rod by 180 ° about the longitudinal axis of the same is rotated with the actuation of the actuation rod in Direction of pressure of the release lever of the latching device no longer reached by the probe, so that none mechanical release of the latch takes place. The one for both Approvals always operated via the rocker switch is used in the case of electrical release that with an unlockable contact, for example a make contact, a trigger magnet is controllable, the on the release lever in the sense of electrical control acts to release the latch. In case of The contacts can be operated mechanically, for example for a visual indication of the mechanical actuation be used.
Eine vorteilhafte Ausgestaltung der Erfindung sieht in diesem
Zusammenhang das Merkmal
Die Erfindung wird durch ein figürlich dargestelltes Ausführungsbeispiel in zwei Figuren näher erläutert, wobei die
- Figur 1
- neben den auf die Betätigungseinrichtung einwirkenden Teile die Schaltstellung der Betätigungsstange zur elektrischen Freigabe zeigt, während in der
Figur 2- die Schaltstellung der Betätigungsstange zur mechanischen Freigabe angedeutet ist.
- Figure 1
- in addition to the parts acting on the actuating device shows the switching position of the actuating rod for electrical release, while in the
- Figure 2
- the switching position of the actuating rod for mechanical release is indicated.
In der Figur 1 ist die Betätigungseinrichtung BE auszugsweise dargestellt, die die Verklinkeinrichtung VE mit dem Entriegelungshebel EH enthält. Auf diesen Entriegelungshebel EH kann in der Schaltstellung S2 (Figur 2) die Betätigungsstange BS durch Druck auf den Taster TA in Druckrichtung DR zur mechanischen Freigabe der Verriegelungseinrichtung VE benutzt werden. Außerdem enthält die Betätigungsstange BS den Querstift QS, der in der Verdrehschutzeinrichtung VS durch einen nicht bezeichneten Längsschlitz geführt ist. Mit dieser Verdrehschutzeinrichtung VS ist erreicht, daß sich die Betätigungsstange BS lediglich in zwei um 180° versetzte Schaltstellungen S1 und S2 betätigen läßt, wobei die Schaltstellung S1 die elektrische Freigabe der Verklinkeinrichtung VE andeutet. Wird die Betätigungsstange BS in Druckrichtung DR betätigt, so wird mit dem Querstift QS der Kipphebel KH in Pfeilrichtung bewegt, und damit der Druckschalter DS betätigt. Innerhalb des Druckschalters DS sind frei beschaltbare Kontakte vorgesehen, mit deren Hilfe ein nicht dargestellter Elektromagnet geschaltet werden kann, der in ähnlicher Weise wie der Tastkopf TK der Betätigungsstange BS in der Schaltstellung S2 (Figur 2), auf den Entriegelungshebel EH der Verklinkeinrichtung VE einwirkt.In Figure 1, the actuator BE is excerpt shown that the latching device VE with the unlocking lever EH contains. On this release lever EH can in the switch position S2 (Figure 2) the actuating rod BS by pressing the TA button in the DR direction towards the mechanical one Release of the locking device VE used become. In addition, the actuating rod BS contains the cross pin QS in the anti-rotation device VS by a not designated longitudinal slot is performed. With this Anti-rotation device VS is reached that the operating rod BS only in two switching positions offset by 180 ° S1 and S2 can be operated, the switching position S1 indicates the electrical release of the latching device VE. If the actuating rod BS is actuated in the pressure direction DR, so with the cross pin QS the rocker arm KH in the direction of the arrow moved, and thus the pressure switch DS operated. There are freely switchable contacts within the pressure switch DS provided with the help of a not shown Electromagnet can be switched in a similar way like the probe TK of the actuating rod BS in the switch position S2 (Figure 2), on the release lever EH Latching device VE acts.
Der Wechsel zwischen der elektrischen und der mechanischen Freigabe erfolgt lediglich durch eine um 180° um die Längsachse LA der Betätigungsstange BS gegenüber seiner ersten Schaltstellung S1 veränderten Schaltstellung S2.The change between the electrical and the mechanical Release only takes place by a 180 ° around the longitudinal axis LA the operating rod BS compared to its first Switch position S1 changed switch position S2.
In der Figur 2 ist die Betätigungsstange BS dargestellt, deren Tastkopf TK gegenüber der elektrischen Freigabe in Schaltstellung S1 (Figur 1) um 180° um die Längsachse LA gedreht ist, so daß mit der Schaltstellung S2 die mechanische Freigabe der Verklinkeinrichtung VE (Figur 1) steuerbar ist.The actuating rod BS is shown in FIG. 2, whose probe TK compared to the electrical release in Switch position S1 (Figure 1) by 180 ° around the longitudinal axis LA is rotated so that the mechanical position S2 Release of the latching device VE (Figure 1) is controllable.
