Abstract

The low-voltage power circuit breaker which has ON, OFF and TRIP positions is able to separate the contact pieces (1, 2) very quickly after tripping in response to an excess current. The excess current trip device in this case acts directly on a transmission lever (10) which on the one hand unlatches a switching-off latch (8) and on the other hand releases the support from two pivoting discs (14) which are spring-loaded in the switching-off direction. Thereafter, two mutually separated mechanical systems are accelerated. The first system, consisting only of the transmission lever (10), of the switching-off latch (8), of a switching-off lever (5) with an energy-storing switching-off spring (6) and of the moving contact piece (2) carries out the contact separation very quickly. The second system, which is now separated from the first system and contains all the other parts of the mechanical drive, is moved by the pivoting discs (14) which are spring-loaded in the switching-off direction. When the power circuit breaker is switched on and off by hand, the two systems are coupled to one another. Switching on by hand takes place independently of the operator's speed of operation, by releasing a switching-on latch (34) of the spring-loaded moving contact piece (2). <IMAGE>

Description

Die vorliegende Erfindung betrifft einen handbetätigbaren Niederspannungs-Leistungsschalter mit von aussen erkennbaren EIN-, AUS- und TRIP-Stellungen, mit einem durch eine Ausschaltfeder belasteten, während einer Ausschaltbewegung und in den AUS- und TRIP-Stellungen auf ein bewegliches Kontaktstück wirkenden Ausschalthebel, der sich in der EIN-Stellung des Schutzschalters auf einer ortsfest gelagerten, durch einen thermischen und/oder durch einen dynamischen Ueberstromauslöser lösbaren Ausschaltklinke abstützt.The present invention relates to a manually operable low-voltage circuit breaker with externally recognizable ON, OFF and TRIP positions, with an opening lever loaded by an opening spring, during an opening movement and in the OFF and TRIP positions acting on a movable contact piece is supported in the ON position of the circuit breaker on a stationary release pawl which can be released by a thermal and / or by a dynamic overcurrent release.

Aus der CH-A-662210 ist ein Niederspannungs-Leistungsschalter der eingangs erwähnten Art bekannt. Dieser Schalter wird als Motorschutzschalter eingesetzt. Die nach einer Kurzschlussauslösung stattfindende Trennung zwischen dem Festkontaktstück und dem beweglichen Kontaktstück erfolgt im allgemeinen bei Motorschutzschaltern verhältnismässig langsam, so dass ein Motorschutzschalter nicht als Kurzschlusstrombegrenzer verwendet werden kann. Bei einem Leistungsschalter mit kurzschlusstrombegrenzenden Eigenschaften ist eine sehr rasche Trennung der Kontaktstücke erforderlich, um den Schaltlichtbogen noch während dem ersten Anstieg des Kurzschlusstromes, vor Erreichen des ersten Maximalwertes zünden zu können.From CH-A-662210 a low-voltage circuit breaker of the type mentioned at the outset is known. This switch is used as a motor protection switch. The separation between the fixed contact piece and the movable contact piece, which takes place after a short-circuit release, generally takes place relatively slowly in the case of motor protection switches, so that a motor protection switch cannot be used as a short-circuit current limiter. In the case of a circuit breaker with short-circuit current-limiting properties, a very rapid disconnection of the contact pieces is required in order to be able to ignite the switching arc even during the first increase in the short-circuit current before the first maximum value is reached.

Aus der US-A-3935409 ist ein strombegrenzender Niederspannungs-Leistungsschalter bekannt. Bei diesem Schalter werden bei einer auf eine Ueberstromauslösung folgenden Kontakttrennung sowohl das bewegliche Kontaktstück, als auch alle zur Betätigung des beweglichen Kontaktstückes dienenden Teile des mechanischen Antriebes durch eine Ausschaltfeder beschleunigt. Die beträchtliche zu beschleunigende Masse und die Reibungswiderstände der bewegten Teile sind dabei für eine verhältnismässig langsame Kontakttrennung verantwortlich. Um im Falle eines Kurzschlusses eine ausreichend schnelle Kontaktöffnung zu erreichen, wird bei dieser Anordnung das Gegenkontaktstück zum beweglichen Kontaktstück auch beweglich gelagert und durch die durch einen Eisenring verstärkte elektromagnetische Wirkung des Kurzschlusstromes vom beweglichen Kontaktstück wegbewegt. Durch diese Massnahme ist die Kontaktöffnung dieses Leistungsschalters zwar beschleunigt aber stromabhängig. Eine stromabhängige Kontaktöffnungszeit ist für einen schnellschaltenden Leistungsschalter insbesondere bei der Unterbrechung relativ kleiner Kurzschlusströme nachteilig, weil die Lichtbogenzeit sich über den ersten Stromnulldurchgang erstrecken kann. Die nachgeschalteten, nicht für Kurzschlusstromunterbrechung ausgebildeten Unterbrecheröffnen und schliessen aberzeitabhängig und nicht stromabhängig. Somit sind in einer solchen Schaltanordnung Betriebsstörungen nicht auszuschliessen. Ausserden muss dieser Leistungsschalter gegen die Ausschaltfeder des beweglichen Kontaktstückes von Hand direkt eingeschaltet werden. Dabei nähern sich die getrennten Kontaktstücke von der Betätigungsgeschwindigkeit der Bedienungsperson abhängig, wobei am Ende der Einschaltbewegung noch die Verklinkungen der beiden federbelasteten Gegenkontaktstücke gelöst werden müssen. Es ist schwierig das gleichzeitige Schliessen der beiden Gegenkontaktstücke zu erreichen. Deshalb sind Vorzündungen mindestens zu einem der Gegenkontaktstücke kaum vermeidbar. Dies ist aber insbesondere dann nachteilig, wenn auf einen verhältnismässig hohen Strom eingeschaltet wird. Der Kontaktabbrand kann dabei bedeutend und auf die beiden Gegenkontaktstücke ungleichmässig verteilt sein. Ein übermässiger Kontaktabbrand verkürzt die Lebensdauer des Leistungsschalters. Ein ungleichmässiger Kontaktabbrand kann die Schalteigenschaften des Leistungsschalters unerwünschterweise verändern.A current-limiting low-voltage circuit breaker is known from US-A-3935409. With this switch, in the event of a contact separation following an overcurrent release, both the movable contact piece and all the parts of the mechanical drive used to actuate the movable contact piece are accelerated by a switch-off spring. The considerable mass to be accelerated and the frictional resistance of the moving parts are responsible for a relatively slow contact separation. In order to achieve a sufficiently quick contact opening in the event of a short circuit, in this arrangement the mating contact piece to the movable contact piece is also movably mounted and moved away from the movable contact piece by the electromagnetic effect of the short circuit current, which is increased by an iron ring. With this measure, the contact opening of this circuit breaker is accelerated but dependent on the current. A current-dependent contact opening time is disadvantageous for a fast-switching circuit breaker, in particular when relatively small short-circuit currents are interrupted, because the arcing time can extend over the first current zero crossing. The downstream interrupters, which are not designed for short-circuit current interruption, open and close depending on time and not on current. In such a switching arrangement, malfunctions cannot be ruled out. In addition, this circuit breaker must be switched on directly against the opening spring of the movable contact piece by hand. The separated contact pieces approach depending on the operating speed of the operator, the latches of the two spring-loaded counter-contact pieces still having to be released at the end of the switch-on movement. It is difficult to achieve the simultaneous closing of the two counter contact pieces. Therefore, preignitions to at least one of the mating contact pieces can hardly be avoided. However, this is particularly disadvantageous when switching to a relatively high current. The contact erosion can be significant and unevenly distributed over the two counter contact pieces. Excessive contact erosion shortens the life of the circuit breaker. Uneven contact erosion can undesirably change the switching properties of the circuit breaker.

Aufgabe der vorliegenden Erfindung ist es, einen Niederspannungs-Leistungsschalter der eingangs erwähnten Gattung vorzuschlagen, der bei jeder Grösse des zu unterbrechenden Stromes eine Kontakttrennung während dem ersten Anstieg des Kurzschlussstromes, vor Erreichen des ersten Maximalwertes und zwar jedesmal im wesentlichen im gleichen Zeitbereich durchführt und eine sprunghafte, von der Betätigungsgeschwindigkeit der Bedienungsperson unabhängige Einschaltung des Leistungsschalters ermöglicht.The object of the present invention is to propose a low-voltage circuit breaker of the type mentioned at the outset which, for each size of the current to be interrupted, carries out a contact separation during the first increase in the short-circuit current, before reaching the first maximum value, and in each case essentially in the same time range, and one allows the circuit breaker to be switched on suddenly, regardless of the operating speed of the operator.

  • f). on the actuating shaft a cam having a radially projecting extension is fastened in a rotationally fixed manner, the extension swiveling the arm of the rocker carrying the support pin radially inward during a switch-off movement carried out by hand until the other arm of the rocker swings the transmission lever away from the swivel plates and so on both the latching between the swivel plates and the transmission lever and the stripping pawl release,
  • G). the actuating shaft has a radial cam provided with an axially protruding driving pin, the cam being in towing connection with the engagement pawl and at the end of an engagement movement by swiveling the engagement pawl unlatching the movable contact piece loaded by an engagement spring and in the ON position the engagement pawl in the unlatched position stops, the cam tipping the rocker and the rocker locking member back into the latched position during a manual switch-off movement,
  • H). there is a driver pin between the two swivel plates, which takes the switch-off lever with it during a switch-on movement and thus tensions the switch-off spring.

Dieser Niederspannungs-Leistungsschalter ist in der Lage eine sehr schnelle Trennung zwischen dem beweglichen Kontaktstück und den Festkontaktstücken durchzuführen, weil der Ueberstromauslöser direkt auf den Uebertragungshebel wirkt, wobei der Uebertragungshebel einerseits die Ausschaltklinke entklinkt und anderseits die Abstützung der in Ausschaltrichtung federbelasteten Schwenkscheiben freigibt. Durch diese Massnahmen erreicht man, dass nach einer Ueberstromauslösung zwei voneinander entkoppelte mechanische Systeme voneinander getrennt beschleunigt werden. Das erste System besteht aus dem Uebertragungshebel, aus der Ausschaltklinke, aus dem Ausschalhebel mit der Ausschaltfeder. Dieses System wirkt sehr schnell auf das bewegliche Kontaktstück. Das zweite, alle anderen Teile des mechanischen Antriebes enthaltende System wird getrennt vom ersten System durch die in Ausschaltrichtung federbelasteten Schwenkscheiben beschleunigt. Dieser Leistungsschalter weist kurzschlusstrombegrenzende Eigenschaften auf. Die Einschaltung des Leistungsschalters erfolgt unabhängig von der Bedienungsgeschwindigkeit der Bedienungsperson durch Freigabe des beweglichen, durch die Einschaltfeder beaufschlagten Kontaktstückes mittels der Einschaltklinke.This low-voltage circuit breaker is able to perform a very quick separation between the movable contact piece and the fixed contact pieces because the overcurrent release acts directly on the transmission lever, the transmission lever on the one hand unlatching the release pawl and on the other hand releasing the support of the spring washers which are spring-loaded in the opening direction. These measures ensure that two mechanical systems decoupled from one another are accelerated separately after an overcurrent trip. The first system consists of the transmission lever, the release pawl, the release lever with the release spring. This system acts very quickly on the moving contact piece. The second system, which contains all the other parts of the mechanical drive, is accelerated separately from the first system by the swivel plates which are spring-loaded in the direction of switch-off. This circuit breaker has short-circuit current limiting properties. The circuit breaker is switched on independently of the operating speed of the operator by releasing the movable contact piece acted upon by the closing spring by means of the closing pawl.

Vorteilhafterweise ist an der Kurvenscheibe ein nach einer Ueberstromauslösung bei der Rückstellbewegung der Betätigungswelle in die AUS-Stellung den Uebertragungshebel und einen daran anstehenden Auslösestössel zurückstossender Rückstellnocken angebracht. Mit Hilfe des Rückstellnockens kann der durch einen Ueberstromauslösung verschobene Auslösestössel über den Uebertragungshebel einfach in die Ruhelage zurückgestellt werden.Advantageously, on the cam plate, after an overcurrent release during the return movement of the actuating shaft into the OFF position, the transfer lever and a resetting cam resetting against it are attached. With the help of the reset cam, the trigger plunger, which has been displaced by an overcurrent release, can easily be returned to the rest position via the transmission lever.

In den Figuren 1 bis 12 ist insbesondere der mechanische Antrieb eines handbetätigbaren Niederspannungs-Leistungsschalters in verschiedenen Schaltstellungen und Zwischenstellungen schematisch dargestellt, wobei bestimmte Teile des Antriebes entweder schraffiert oder auffallend dick ausgezogen sind, um den Bewegungsablauf dieser Teile während den Schaltbewegungen besserveranschaulichen zu können. In diesen Figuren sind deshalb auch die Konturen mehrerer, in verschiedenen Ebenen hintereinander liegender Teile übereinander gezeichnet. Die Figuren 13 bis 23 zeigen einige Teile des Antriebes für sich allein in einem anderen Masstab, in Vergrösserung.In Figures 1 to 12 is in particular the mechanical drive of a manually operated low Voltage circuit breaker in different switching positions and intermediate positions shown schematically, with certain parts of the drive either hatched or strikingly thick, in order to better illustrate the movement of these parts during the switching movements. In these figures, therefore, the contours of several parts lying one behind the other in different planes are drawn one above the other. Figures 13 to 23 show some parts of the drive on their own on a different scale, on an enlarged scale.

Der handbetätigbare Niederspannungs-Leistungsschalter ist mit zwei Festkontaktstücken 1 und mit einem beweglichen Kontaktstück 2 ausgerüstet. Auf das bewegliche Kontaktstück 2 wirkt eine nur schematisch angedeutete Einschaltfeder 3. Dieses bewegliche Kontaktstück 2 ist mit einem durch den mechanischen Antrieb betätigbaren Schaltbalken 4 starr verbunden. Auf den Schaltbalken 4 wirkt während einer Ausschaltbewegung und in den AUS- und TRIP-Stellungen (Figuren 1, 5, 6, 7, 11, 12) ein um die Achse 41 schwenkbar gelagerter Ausschalthebel 5, der durch eine Ausschaltfeder 6 belastet ist. In der EIN-Stellung und am Beginn einer Ausschaltbewegung (Figuren 3, 4, 9, 10) des Leistungsschalters stützt sich der Ausschalthebel 5 auf eine im Gehäuse 7 um die Achse 42 schwenkbar gelagerte Ausschaltklinke 8. Ein nicht dargestellter, thermischer und dynamischer Ueberstromauslöser wirkt auf einen Ausschaltstössel 9, der bei einer durch einen Ueberstrom bedingten thermischen oder dynamischen Auslösung einen im Gehäuse 7 um die Achse 43 schwenkbargelagerten Uebertragungshebel 10 aus der Ruhelage schwenkt. Der andere Hebelarm dieses Uebertragungshebels 10 schwenkt seinerseits die Ausschaltklinke 8 aus der Ruhelage und entklinkt dadurch den Ausschalthebel 5.The manually operable low-voltage circuit breaker is equipped with two fixed contact pieces 1 and with a movable contact piece 2. An only schematically indicated closing spring 3 acts on the movable contact piece 2. This movable contact piece 2 is rigidly connected to a switching bar 4 which can be actuated by the mechanical drive. On the switching bar 4 acts during a switch-off movement and in the OFF and TRIP positions (Figures 1, 5, 6, 7, 11, 12) a switch lever 5 which is pivotally mounted about the axis 41 and which is loaded by a switch-off spring 6. In the ON position and at the start of an opening movement (FIGS. 3, 4, 9, 10) of the circuit breaker, the opening lever 5 is supported on an opening pawl 8 which is pivotably mounted in the housing 7 about the axis 42. A thermal and dynamic overcurrent release (not shown) acts to a switch-off plunger 9 which, in the event of thermal or dynamic triggering caused by an overcurrent, pivots a transmission lever 10 which is pivotably mounted in the housing 7 about the axis 43 from the rest position. The other lever arm of this transmission lever 10 in turn pivots the switch-off pawl 8 from the rest position and thereby unlatches the switch-off lever 5.

Für die Handbetätigung des Schutzschalters ist eine um 90° schwenkbar gelagerte, mit einem nicht dargestellten Betätigungshandgriff versehene Betätigungswelle 11 vorgesehen. In den Figuren 1 bis 12 befindet sich die AUS-Stellung der Betätigungswelle 11 (Fig.1, 7) in ihrerin Gegenuhrzeigersinn liegenden Endstellung und die EIN-Stellung (Fig.3, 9) in ihrer Endstellung in Uhrzeigersinn. In der TRIP-Stellung (Fig.5, 11) liegt die Betätigungswelle 11 zwischen diesen beiden Endstellungen. Die Lage des Betätigungshandgriffes lässt dabei von aussen erkennen, in welcher Stellung sich der Schutzschalter befindet. Die Betätigungswelle 11 ist in den Figuren 13 und 14 von der Seite und in Achsrichtung, allein dargestellt. Auf dieser Betätigungswelle 11 sind an den Stellen 12 und 13 zwei Schwenkscheiben 14 schwenkbar gelagert. Die an der Stelle 13 gelagerte Schwenkscheibe 14 ist in der Figur 15 allein dargestellt. Die an der Stelle 12 gelagerte Schwenkscheibe weist die gleichen Konturen auf wie die Schwenkscheibe 14 in Fig.15. Diese beiden, an den Stellen 12 und 13 auf der Betätigungswelle 11 gelagerten Schwenkscheiben 14 sind durch in die Bohrungen 16, 17, 16 eingesetzte, nicht näher dargestellte Querbolzen miteinander starr verbunden und zugleich beabstandet. Die miteinander verbundenen Schwenkscheiben 14 sind in Ausschaltrichtung, in den Figuren 1 bis 12 in Gegenuhrzeigersinn federbelastet. Die beiden Schwenkscheiben 14 weisen Rastnasen 19 auf, auf welchen sich der Uebertragungshebel 10 in der EIN-Stellung des Schutzschalters (Fig.3, 9) abstützt. Nach einer thermischen oder dynamischen Auslösung des Schutzschalters wird der Uebertragungshebel 10 von den Schwenkscheiben 14 weggeschwenkt, worauf sich die Schwenkscheiben 14 aufgrund der Federwirkung in Ausschaltrichtung, in Gegenuhrzeigersinn bewegen.For the manual operation of the circuit breaker, an actuating shaft 11 is provided which is pivotable through 90 ° and is provided with an actuating handle, not shown. In Figures 1 to 12, the OFF position of the actuating shaft 11 (Fig. 1, 7) is in its counterclockwise end position and the ON position (Fig. 3, 9) is in its end position in a clockwise direction. In the TRIP position (Fig. 5, 11), the actuating shaft 11 lies between these two end positions. The position of the operating handle reveals the position of the circuit breaker from the outside. The actuating shaft 11 is shown in Figures 13 and 14 from the side and in the axial direction, alone. On this actuating shaft 11, two swivel plates 14 are pivotably mounted at points 12 and 13. The swivel disk 14 mounted at point 13 is shown in FIG. 15 alone. The swivel disk mounted at point 12 has the same contours as the swivel disk 14 in FIG. 15. These two, at the points 12 and 13 mounted on the actuating shaft 11 swivel plates 14 are rigidly connected to one another and at the same time spaced by transverse bolts, not shown, inserted into the bores 16, 17, 16. The interconnected swivel plates 14 are spring-loaded in the switch-off direction, counterclockwise in FIGS. 1 to 12. The two swivel plates 14 have locking lugs 19 on which the transmission lever 10 is supported in the ON position of the circuit breaker (FIGS. 3, 9). After a thermal or dynamic triggering of the circuit breaker, the transmission lever 10 is pivoted away from the swivel plates 14, whereupon the swivel plates 14 move counterclockwise due to the spring action in the switch-off direction.

Im Randbereich der Schwenkscheiben 14 ist auf einem in die Bohrungen 18 eingesetzten ersten Verbindungsbolzen eine in den Figuren 17 und 18 aus der Richtung der Schwenkachse und von der Seite her dargestellte Wippe 20 schwenkbar gelagert. Am einen von diesem Verbindungsbolzen in Ausschaltrichtung oder in Gegenuhrzeigersinn liegenden Arm der Wippe 20 ist eine Stützfläche 27 vorgesehen. Am anderen, von der Lagerung der Wippe 20 in Einschaltrichtung oder in Uhrzeigersinn liegenden Arm der Wippe 20 ist ein seitlich der Wippe 20 vorstehender Stützstift 23 angeordnet. Auf einem zweiten, in die Bohrungen 17 der Schwenkscheiben 14 eingesetzten Verbindungsbolzen ist ein in Uhrzeigersinn federbelastetes Wippen-Sperrglied 24 schwenkbar gelagert. Dieses Wippen-Sperrglied 24 ist in den Figuren 19 und 20 von der Seite her und in der Achsrichtung seiner Lagerung dargestellt. Die auf das Wippen-Sperrglied 24 wirkende Feder ist aus Gründen der besseren Uebersichtlichkeit nicht dargestellt, es handelt sich um eine auf den Fortsatz 25 aufgewickelten, auf dem Wippen-Sperrglied 24 und auf der Schwenkscheibe 14 abgestützte Schenkelfeder. Die Sperrfläche 26 des Wippen-Sperrgliedes 24 liegt in der AUS-Stellung des Schutzschalters (Fig.1, 7) an der Stützfläche 27 der Wippe 20. Der seitlich vorstehende Fortsatz 29 des Wippen-Sperrgliedes 24 stösst bei einer in Fig.2 und 8 gezeigten Einschaltbewegung des Schutzschalters an einem ortsfesten Anschlag 30 an, wonach das Wippen-Sperrglied 24 in Gegenuhrzeigersinn gekippt wird und die Sperrungen freigegeben werden.In the edge region of the swivel plates 14, a rocker 20, which is shown in FIGS. 17 and 18 from the direction of the swivel axis and from the side, is pivotably mounted on a first connecting bolt inserted into the bores 18. A support surface 27 is provided on one arm of the rocker 20 lying in the switch-off direction or in the counterclockwise direction of this connecting bolt. On the other, from the mounting of the rocker 20 in the switch-on direction or clockwise arm of the rocker 20, a support pin 23 projecting to the side of the rocker 20 is arranged. A clockwise spring-loaded rocker locking element 24 is pivotably mounted on a second connecting bolt inserted into the bores 17 of the swivel plates 14. This rocker locking member 24 is shown in Figures 19 and 20 from the side and in the axial direction of its storage. The spring acting on the rocker locking element 24 is not shown for reasons of better clarity, it is a leg spring which is wound onto the extension 25, supported on the rocker locking element 24 and on the swivel plate 14. The blocking surface 26 of the rocker blocking element 24 lies in the OFF position of the circuit breaker (FIGS. 1, 7) on the supporting surface 27 of the rocker 20. The laterally projecting extension 29 of the rocking blocking element 24 abuts one in FIGS. 2 and 8 Switching-on movement of the circuit breaker shown on a stationary stop 30, after which the rocker locking member 24 is tilted counterclockwise and the locks are released.

Auf der Betätigungswelle 11 ist eine einen radial vorstehenden Fortsatz 22 aufweisende Kurvenscheibe 21 verdrehungsfest befestigt. Diese Kurvenscheibe 21 ist in den Figuren 21, 22 und 23 von drei Seiten in einem anderen Masstab dargestellt. Der Fortsatz 22 kommt bei einer von Hand durchgeführten Ausschaltbewegung mit dem Stützstift 23 in Eingriff und schwenkt den den Stützstift 23 tragenden Arm der Wippe 20 so weit radial nach innen, bis der andere Arm der Wippe 20 den Uebertragungshebel 10 von den Rastnasen 19 der Schwenkscheiben 14 wegdrückt. Auf dieser Weise wird einerseits die Verrastung zwischen den Schwenkscheiben 14 und dem Uebertragungshebel 10 und anderseits die Ausschaltklinke 8 gelöst.On the actuating shaft 11 has a radially projecting extension 22 cam 21 is fixed against rotation. This cam disk 21 is shown in another scale on three sides in FIGS. 21, 22 and 23. The extension 22 comes into engagement with the support pin 23 during a switch-off movement carried out by hand and pivots the arm of the rocker 20 carrying the support pin 23 radially inwards until the other arm of the rocker 20 pushes the transmission lever 10 away from the locking lugs 19 of the swivel plates 14. In this way, on the one hand, the latching between the swivel plates 14 and the transmission lever 10 and, on the other hand, the switch-off pawl 8 is released.

Die Betätigungswelle 11 ist mit einem radialen Nocken 31 versehen, der einen axial vorstehenden Mitnehmerstift 32 trägt. Der Mitnehmerstift 32 ragt im zusammengebauten Schutzschalter durch den kreisbogenförmigen Durchbruch 15 der an der Stelle 13 der Betätigungswelle 11 gelagerten Schwenkscheibe 14 hindurch und steht unter der Wirkung einer nicht dargestellten Feder. Ueber den Anschlag 33 wird die in Fig.16 allein gezeichnete Einschaltklinke 34 mit dem Nocken 31 in Schleppverbindung gesetzt. Die Einschaltklinke 34 ist nämlich mit ihrer Bohrung 35 auf die Betätigungswelle 11 im Bereich 12 zwischen der Schwenkscheibe 14 und dem Nocken 31 schwenkbaraufgeschoben. Die Einschaltklinke 34 ist in den in Figuren 1 bis 12 gezeigten Anordnungen in Gegenuhrzeigersinn durch eine nicht dargestellte Feder belastet.The actuating shaft 11 is provided with a radial cam 31 which carries an axially protruding driving pin 32. The driver pin 32 protrudes in the assembled circuit breaker through the arcuate opening 15 of the swivel plate 14 mounted at the point 13 of the actuating shaft 11 and is under the action of a spring, not shown. Via the stop 33, the switch pawl 34, which is drawn only in FIG. 16, is set in drag connection with the cam 31. The engaging pawl 34 is namely pushed with its bore 35 onto the actuating shaft 11 in the area 12 between the swivel plate 14 and the cam 31. In the arrangements shown in FIGS. 1 to 12, the switch pawl 34 is loaded counterclockwise by a spring, not shown.

Zwischen den beiden Schwenkscheiben 14 ist ein in den Bohrungen 16 der Schwenkscheiben 14 befestigter Mitnehmerbolzen 37 vorhanden, der bei einer Einschaltbewegung des Schutzschalters den Ausschalthebel 5 an der Fläche 38 mitnimmt und so die Ausschaltfeder 6 spannt.Between the two swivel plates 14 there is a driver pin 37 which is fastened in the bores 16 of the swivel plates 14 and which, when the circuit breaker is switched on, picks up the switch-off lever 5 on the surface 38 and thus tensions the switch-off spring 6.

Die Funktionsweise des handbetätigbaren Schutzschalters wird im folgenden anhand der einzelnen Schaltzustandsänderungen beschrieben.The mode of operation of the manually operated circuit breaker is described below on the basis of the individual switching state changes.

VON HAND EINSCHALTEN - (AUS - EIN)SWITCH ON BY HAND - (OFF - ON)

In den Figuren 1 und 7 ist der Schutzschalter in derAUS-Stellung dargestellt. In Fig.1 sind die Wippe 20 mit gestrichelten Linien, das Wippen-Sperrglied 24 mit Zweipunkt-Strich Linien und die Betätigungswelle 11 mit Einpunkt-Strich Linien schraffiert. In den weiteren Figuren 2 bis 6 bleibt diese Schraffur erhalten. In Fig.7 sind die Konturen der Schwenkscheibe 14 mit durchgehender, dicker Linie gezeichnet. Die Kurvenscheibe 21 wurde dabei schraffiert und die Konturen eines damit einteiligen Rückstellnockens 39 mit gestrichelter Linie auffallend dick ausgezogen. In den Figuren 8 bis 12 ist diese Darstellung gleichbleibend. In der in den Figuren 1 und 7 dargestellten AUS-Stellung ist die Ausschaltfeder 6 entspannt und der Ausschalthebel 5 steht am Schaltbalken 4 an. Die Einschaltklinke 34 verrastet den Schaltbalken 4 in der AUS-Stellung. Die Betätigungswelle 11 befindet sich in ihrer in Gegenuhrzeigersinn liegenden Endstellung, was von aussen an der Lage des an der Betätigungswelle 11 befestigten Betätigungshandgriffes als AUS-Stellung erkannt werden kann.Figures 1 and 7 show the circuit breaker in the OFF position. In Figure 1, the rocker 20 are hatched with dashed lines, the rocker locking member 24 with two-dot chain lines and the actuating shaft 11 with one-dot chain lines. This hatching is retained in the further FIGS. 2 to 6. In Figure 7, the contours of the swash plate 14 are drawn with a continuous, thick line. The cam disc 21 was hatched and the contours of a one-piece reset cam 39 with a dashed line drawn out strikingly thick. This representation is constant in FIGS. 8 to 12. In the OFF position shown in FIGS. 1 and 7, the switch-off spring 6 is relaxed and the switch-off lever 5 is in contact with the switching bar 4. The switch pawl 34 locks the switch bar 4 in the OFF position. The actuating shaft 11 is in its counterclockwise end position, which can be recognized from the outside by the position of the actuating handle attached to the actuating shaft 11 as an OFF position.

Jetzt wird die Betätigungswelle 11 mittels des Betätigungshandgriffes in Uhrzeigersinn gedreht, bis der mechanische Antrieb die in den Figuren 2 und 8 dargestellte Stellung erreicht. Die Betätigungswelle steht in dieser Stellung an der Grenze des Kippens der Teile der Wippe 20 und des Wippensperrgliedes 24, wonach es kein Zurück mehr gibt. Wie man aus dem Vergleich der Figuren 1 und 2 sowie 7 und 8 feststellen kann, hat der Nocken 31 der Betätigungswelle 11 die Wippe 20 und somit auch die beiden Schwenkscheiben 14 in Uhrzeigersinn mitgenommen. Derzwischen den Schwenkscheiben 14 befestigte Mitnehmerbolzen 37 hat den Ausschalthebel 5 an der Fläche 38 angegriffen und auch mitgenommen, wodurch die Ausschaltfeder 6 gespannt wurde. Die in Gegenuhrzeigersinn federbelastete Ausschaltklinke 8 steht bereits unter dem Ausschalthebel 5 und der Uebertragungshebel 10 bereits vor der Rastnase 19. Der Fortsatz 29 des Wippen-Sperrgliedes 24 steht gerade am ortsfesten Anschlag 30 an. Beim Weiterdrehen der Betätigungswelle 11 in Uhrzeigersinn wird das Wippen-Sperrglied 24 in Gegenuhrzeigersinn gekippt, wodurch die Sperrung der Wippe 20 aufgehoben wird. Nach Aufhebung der Sperrung der Wippe 20 kann die Betätigungswelle 11 weitergedreht werden, wobei die Wippe 20 die in den Figuren 3 und 9 dargestellte Stellung annimmt. Der radiale Nocken 31 stösst am Anschlag 33 der Einschaltklinke 34 an und schwenkt diese in Uhrzeigersinn vom Schaltbalken 4 weg. In diesem Moment kann die Einschaltfeder 3 wirksam werden und bringt das nicht mehr verklinkte bewegliche Kontaktstück 2 mit den Festkontaktstücken 1 in Eingriff. Die Figuren 3 und 9 zeigen diesen eingeschalteten Zustand des Schutzschalters.Now the actuating shaft 11 is rotated clockwise by means of the actuating handle until the mechanical drive reaches the position shown in FIGS. 2 and 8. The actuating shaft is in this position on the limit of the tilting of the parts of the rocker 20 and the rocker locking member 24, after which there is no turning back. As can be seen from the comparison of FIGS. 1 and 2 and 7 and 8, the cam 31 of the actuating shaft 11 has taken the rocker 20 and thus also the two swivel plates 14 in a clockwise direction. The driver pin 37 fastened between the swivel plates 14 has attacked the take-off lever 5 on the surface 38 and has also taken it along, as a result of which the turn-off spring 6 has been tensioned. The counterclockwise spring-loaded shut-off pawl 8 is already under the shut-off lever 5 and the transmission lever 10 is already in front of the locking lug 19. The extension 29 of the rocker locking member 24 is just against the fixed stop 30. When the actuating shaft 11 continues to rotate clockwise, the rocker locking member 24 is tilted counterclockwise, whereby the locking of the rocker 20 is released. After the blocking of the rocker 20 has been released, the actuating shaft 11 can be rotated further, the rocker 20 assuming the position shown in FIGS. 3 and 9. The radial cam 31 abuts the stop 33 of the switch pawl 34 and swivels it clockwise away from the switching beam 4. At this moment, the closing spring 3 can take effect and brings the no longer pinned movable contact piece 2 into engagement with the fixed contact pieces 1. Figures 3 and 9 show this switched-on state of the circuit breaker.

VON HAND AUSSCHALTEN - (EIN - AUS)SWITCH OFF BY HAND - (ON - OFF)

Um den Schutzschalter von Hand auszuschalten, wird die Betätigungswelle 11 in Gegenuhrzeigersinn gedreht. Der radiale Nocken 31 wird dabei bis zum Erreichen der in den Figuren 4 und 10 dargestellten Zwischenstellung unter der Wippe 20 gedreht. Die Einschaltklinke 34 dreht sich auf Wirkung der sie belastenden Feder in Gegenuhrzeigersinn, sobald der Nocken 31 und der Anschlag 33 der Einschaltklinke 34 geschwenkt werden. Die Einschaltklinke 34 steht am Schaltbalken 4 an, wie es in den Figuren 4 und 10 gezeigt ist. Beim Weiterdrehen der Betätigungswelle 11 schwenkt der radiale Nocken 31 die Wippe 20 in Uhrzeigersinn. Der an der Kurvenscheibe 21 angeformte Fortsatz 22 greift dabei am Stützstift 23 an und schwenkt die Wippe 20 in Uhrzeigersinn so weit, bis der andere Arm der Wippe 20 den Uebertragungshebel 10 von den Rastnasen 19 der Schwenkscheiben 14 wegdrückt, wodurch einerseits die federbelasteten Schwenkscheiben 14 freigegeben werden und anderseits aber zur gleichen Zeit auch die Ausschaltklinke 8 geschwenkt und somit die Verklinkung des Ausschalthebels 5 entklinkt wird. DerAusschalthebel 5 stösst den Schaltbalken 4 und das bewegliche Kontaktstück 2 in die AUS-Stellung. Das federbelastete Wippen-Sperrglied 24 kann, nachdem die Ecken der Wippe 20 und des Wippen-Sperrgliedes 24 am Ende der Schwenkbewegung der Wippe 20 ausser Eingriff gekommen sind, in Gegenuhrzeigersinn in die Ruhestellung kippen. Die beiden Schwenkscheiben 14 erreichen die in den Figuren 1 und 7 gezeigte AUS-Stellung auf Wirkung einer sie in Gegenuhrzeigersinn belastenden Feder. Die Einschaltklinke 34 sperrt in der AUS-Stellung den Schaltbalken 4 und hält das bewegliche Kontaktstück in der AUS-Stellung. Die Figuren 1 und 7 zeigen den Schutzschalter in der AUS-Stellung.In order to switch off the circuit breaker by hand, the actuating shaft 11 is rotated counterclockwise. The radial cam 31 is rotated under the rocker 20 until the intermediate position shown in FIGS. 4 and 10 is reached. The pawl 34 rotates counterclockwise on the action of the spring loading it as soon as the cam 31 and the stop 33 of the pawl 34 are pivoted. The switch pawl 34 is on the switching bar 4, as shown in Figures 4 and 10. As the actuating shaft 11 continues to rotate, the radial cam 31 pivots the rocker 20 in a clockwise direction. The extension 22 formed on the cam plate 21 engages the support pin 23 and pivots the rocker 20 clockwise until the other arm of the rocker 20 presses the transmission lever 10 away from the locking lugs 19 of the swivel plates 14, whereby on the one hand the spring-loaded swivel plates 14 are released are and on the other hand at the same time the switch pawl 8 is pivoted and thus the latch of the switch lever 5 is unlatched. The switch-off lever 5 pushes the switch bar 4 and the movable cone clock 2 in the OFF position. The spring-loaded rocker locking element 24 can, after the corners of the rocker 20 and the rocker locking element 24 have come out of engagement at the end of the pivoting movement of the rocker 20, tilt counterclockwise into the rest position. The two swivel plates 14 reach the OFF position shown in FIGS. 1 and 7 on the action of a spring which loads them in the counterclockwise direction. The latch 34 locks the switching bar 4 in the OFF position and holds the movable contact piece in the OFF position. Figures 1 and 7 show the circuit breaker in the OFF position.

UEBERSTROMAUSLOESUNG - (EIN - TRIP)OVERCURRENT RELEASE - (ON - TRIP)

Der eingeschaltete Schutzschalter ist in den Figuren 3 und 9 dargestellt. Bei einer thermischen oder dynamischen Ueberstromauslösung stösst der Auslösestössel 9 auf den Uebertragungshebel 10. Durch Schwenkung des Uebertragungshebels 10 in Gegenuhrzeigersinn wird einerseits die Ausschaltklinke 8 geschwenkt und die durch die Ausschaltklinke 8 bewirkte Verklinkung des Ausschalhebels 5 aufgehoben und anderseits die Verklinkung der Schwenkscheiben 14 freigegeben, weil der Uebertragungshebel 10 von den Rastnasen 19 der Schwenkscheiben 14 weggeschwenkt wird. Die Aufhebung derVerklinkung des Ausschalthebels 5 über ein verhältnismässig wenig Verzögerung verursachendes Zweihebelsystem erlaubt eine sehr schnelle Trennung zwischen dem beweglichen Kontaktstück 2 und den Festkontaktstücken 1. Nach Freigabe der Verklinkung der Schwenkscheiben 14 bewegen sich die Schwenkscheiben 14 in die in den Figuren 5 und 11 dargestellte Stellung. Bei dieser Bewegung werden die durch das Wippen-Sperrglied 24 gesperrte Wippe 20 und das Wippen-Sperrglied 24 selbst in Gegenuhrzeigersinn durch die auf die Schwenkscheiben 14 wirkende Feder mitgenommen, bis das Wippen-Sperrglied 24 am Ausschalthebel 5 ansteht. In dieser Stellung hält der Stützstift 23 der Wippe 20 die Ausschaltklinke 8 in der entklinkten Stellung. Der radiale Nocken 31 der Betätigungswelle 11 hat mit der Wippe 20 keine kraft-oder formschlüssige Verbindung. Deshalb wird die Betätigungswelle 11 und der daran befestigte Betätigungshandgriff über den Mitnehmerstift 32 durch das Ende des Durchbruchs 15 in der Schwenkscheibe 14 in die zwischen den EIN- und AUS-Stellungen liegende TRIP- Stellung mitgenommen. Die Figuren 5 und 11 zeigen den Schutzschalter in der TRIP-Stellung.The activated circuit breaker is shown in Figures 3 and 9. In the event of a thermal or dynamic overcurrent release, the trigger plunger 9 hits the transmission lever 10. By pivoting the transmission lever 10 counterclockwise, the opening pawl 8 is pivoted on the one hand and the latching of the opening lever 5 caused by the opening pawl 8 is released and, on the other hand, the latching of the swivel plates 14 is released because it is released the transmission lever 10 is pivoted away from the locking lugs 19 of the swivel plates 14. The release of the latching of the switch-off lever 5 by means of a two-lever system causing relatively little delay allows a very quick separation between the movable contact piece 2 and the fixed contact pieces 1. After the latching of the swivel plates 14 has been released, the swivel plates 14 move into the position shown in FIGS. 5 and 11 . During this movement, the rocker 20, which is locked by the rocker locking member 24, and the rocker locking member 24 are themselves taken in a counterclockwise direction by the spring acting on the swivel plates 14 until the rocker locking member 24 is in contact with the switch-off lever 5. In this position, the support pin 23 of the rocker 20 holds the switch-off pawl 8 in the unlatched position. The radial cam 31 of the actuating shaft 11 has no non-positive or positive connection with the rocker 20. Therefore, the actuating shaft 11 and the actuating handle attached to it are carried via the driving pin 32 through the end of the opening 15 in the swivel plate 14 into the TRIP position lying between the ON and OFF positions. Figures 5 and 11 show the circuit breaker in the TRIP position.

RUECKSTELLEN - (TRIP -AUS)RESET - (TRIP-OFF)

Um den Schutzschalter nach einer Ueberstromauslösung wieder einschalten zu können, muss der Schutzschalter zuerst aus der TRIP-Stellung in die AUS-Stellung geführt werden. Die TRIP-Stellung ist in den Figuren 5 und 11 dargestellt. Aus dieser Stellung wird die Betätigungswelle 11 in Gegenuhrzeigersinn gedreht, bis die in den Figuren 6 und 12 gezeigte Stellung erreicht ist. Der Rückstellnocken 39 drückt den horizontalen Arm des Uebertragungshebels 10 und damit den Auslösestössel 9 nach oben. Der Auslösestössel 9 kann nur dann nach oben gestossen werden, wenn der thermische und dynamische Ueberstromauslöser sich seinerseits bereits in der unausgelösten Stellung befindet. Wenn der Auslösestössel 9 durch Schwenken des Uebertragungshebels 10 in Uhrzeigersinn nach oben geschoben wird, wird zugleich auch die Wippe 20 über die Ausschaltklinke 8 und über den Stützstift 23 in Uhrzeigersinn zurückgekippt. Durch diese Bewegung der Wippe 20 wird die durch das Wippen-Sperrglied 24 ausgeübte Sperrung aufgehoben und das Wippen-Sperrglied 24 kippt auf Wirkung der ihn belastenden Feder in Uhrzeigersinn in die Ruhestellung. Somit ist die in den Figuren 1 und 7 gezeigte AUS-Stellung erreicht.To be able to switch the circuit breaker back on after an overcurrent trip, the circuit breaker must first be moved from the TRIP position to the OFF position. The TRIP position is shown in Figures 5 and 11. From this position, the actuating shaft 11 is rotated counterclockwise until the position shown in FIGS. 6 and 12 is reached. The reset cam 39 presses the horizontal arm of the transmission lever 10 and thus the trigger plunger 9 upwards. The trigger plunger 9 can only be pushed upwards if the thermal and dynamic overcurrent release is itself already in the untripped position. If the trigger plunger 9 is pushed upwards by swiveling the transmission lever 10 in a clockwise direction, the rocker 20 is also tilted back in a clockwise direction via the release pawl 8 and the support pin 23. As a result of this movement of the rocker 20, the lock exerted by the rocker locking member 24 is released and the rocker locking member 24 tilts clockwise into the rest position due to the spring loading it. The OFF position shown in FIGS. 1 and 7 has thus been reached.
