Schaltgerät mit einer Einrichtung zum sprunghaften Einschalten Switching device with a device for sudden switching
Die Erfindung betrifft ein Schaltgerät mit einer Einrichtung zum sprunghaften Einschalten mit einer Betätigungsmechanik, die ein Betätigungselement aufweist und über eine Übertragungsmechanik mit einem Schaltschloss in Wirkverbindung steht, welches über eine weitere Übertragungsmechanik einen Schalthebel bedient, und mit einer Kontaktanordnung, die ein festes Schaltstück mit Kontakten aufweist, welches gegenüber liegend zu einem beweglichen Schaltstück mit Kontakten angeordnet ist, welches in einem Kontaktschieber geführt ist. The invention relates to a switching device having a device for sudden switching with an actuating mechanism which has an actuating element and is operatively connected via a transmission mechanism with a switch lock, which operates a shift lever via a further transmission mechanism, and with a contact arrangement comprising a fixed contact piece with contacts has, which is opposite lying to a movable contact piece with contacts, which is guided in a contact slide.
Schaltgeräte, insbesondere Leistungsschalter, dienen unter Anderem dem sicheren Abschalten bei einem Kurzschluss und schützen dadurch Verbraucheranlagen. Ferner eignen sich elektrische oder mechanische Schalteinheiten für das betriebsmäßige manuelle Schalten von Verbrauchern sowie zur sicheren Trennung einer Anlage vom Stromnetz bei Wartungsarbeiten oder bei Änderungen an der Anlage. Elektrische Schalteinheiten werden häufig elektromagnetisch betrieben. Switching devices, in particular circuit breakers, serve, among other things, the safe switching off in the event of a short circuit and thereby protect consumer installations. Furthermore, electrical or mechanical switching units are suitable for the operational manual switching of consumers as well as for the safe disconnection of a system from the mains during maintenance work or when changing the system. Electrical switching units are often operated electromagnetically.
Das heißt, derartige Schalteinheiten sind technisch hochwertige elektrische Schaltgeräte mit integriertem Schutz für Motoren, Leitungen, Transformatoren und Generatoren. Näheren Einsatz finden sie an Funktionsstellen mit geringerer Schalthäufigkeit. Derartige Schalteinheiten sind neben dem Kurzschlussschutz auch für den Überlastschutz geeignet. That is, such switching units are high-quality electrical switching devices with integrated protection for motors, lines, transformers and generators. They are used more closely at workstations with a lower switching frequency. Such switching units are suitable in addition to the short circuit protection for overload protection.
Im Fall eines Kurzschlusses schaltet eine elektrische Schalteinheit eine elektrische Anlage sicher ab. Somit bietet diese einen Sicherungsschutz vor Überlastung. Jeder Leiter durch den Strom fließt, erwärmt sich mehr oder weniger stark. Die Erwärmung hängt dabei vom Verhältnis der Stromstärke zum Stromleiterquerschnitt ab, der so genannten Stromdichte. Die Stromdichte darf nicht zu groß werden, da sonst durch zu hohe Erwärmung die Leiterisolationen verschmoren oder möglicherweise ein Brand ausgelöst werden kann. Um elektrische Anlagen gegen diese schädigenden Auswirkungen zu schützen, werden Schalteinheiten als Überstrom-Schutzeinrichtungen verwendet. In the case of a short circuit, an electrical switching unit switches off an electrical system safely. Thus, this provides a protection against overload. Each conductor flows through the stream, heats up more or less strongly. The heating depends on the ratio of the current to the conductor cross-section, the so-called current density. The current density must not be too large, otherwise by too high Heating may contaminate the conductor insulation or possibly cause a fire. To protect electrical equipment against these damaging effects, switching units are used as overcurrent protective devices.
Leistungsschalter weisen zwei voneinander getrennt wirkende Auslösemechanismen für den Überlast- und Kurzschlussschutz auf. Beide Auslöser sind in Reihe geschaltet. Den Schutz beim Kurzschluss übernimmt ein zeitlich nahezu unverzögert wirkender elektrischer Auslöser. Bei einem Kurzschluss entklinkt der elektromagnetische Auslöser unverzögert ein Schaltschloss des Leistungsschalters. Ein Schaltanker trennt das Schaltstück, ehe der Kurzschlussstrom seinen Höchstwert erreichen kann . Circuit breakers have two separate release mechanisms for overload and short-circuit protection. Both triggers are connected in series. The short-circuit protection is provided by an electrical release that works almost instantaneously. In the event of a short circuit, the electromagnetic release unlocks without delay a circuit breaker of the circuit breaker. A switching armature disconnects the contactor before the short-circuit current can reach its maximum value.
Bekannte Schalteinheiten weisen eine Kontaktschiebereinheit mit einem Kontaktschieber und einem beweglichen Schaltstück auf. Das bewegliche Schaltstück weist ferner elektrische Kontakte auf. Ferner weisen derartige Schalteinheiten erste Kontakte zu einer Stromleitung auf. In einem eingeschalteten Zustand kontaktieren die elektrischen Kontakte des beweglichen Schaltstücks die festen Kontakte der Schalteinheit. Im Kurzschlussfall werden die elektrischen Kontakte des beweglichen Schaltstücks von den festen Kontakten gelöst, so dass der Stromfluss unterbrochen wird. Hierbei wird das bewegliche Schaltstück von den festen Kontakten gelöst. Known switching units have a contact slide unit with a contact slide and a movable contact piece. The movable contact piece also has electrical contacts. Furthermore, such switching units have first contacts to a power line. In an on state, the electrical contacts of the movable contact piece contact the fixed contacts of the switching unit. In the event of a short circuit, the electrical contacts of the movable contact piece are released from the fixed contacts, so that the flow of current is interrupted. Here, the movable contact is released from the fixed contacts.
Leistungsschalter erfüllen neben ihren Schutzfunktionen als Überlast- und Kurzschlussauslöser, wie oben schon erwähnt, auch das normative Ein- und Ausschalten von Motoren. Zum Nachweis dieser Funktion müssen die Leistungsschalter nach der Produktnorm den zehnfachen Motornennstrom einschalten können. Um diese Grenzbelastung gewährleisten zu können ist es notwendig, dass der Leistungsschalter die Doppelunterbrechung der drei Strombahnen in Form jeweils einer beweglichen Brücke mit zwei Kontaktstellen und zwei festen Kontaktstellen, nahezu gleichzeitig und in einer Sprungfunktion In addition to their protective functions as overload and short-circuit releases, as already mentioned above, circuit breakers also fulfill the normative switching on and off of motors. To prove this function, the circuit-breakers must be able to switch on ten times the rated motor current according to the product standard. In order to ensure this limit load, it is necessary that the circuit breaker the double interruption of the three current paths in the form of a movable bridge with two contact points and two fixed contact points, almost simultaneously and in a jump function
schließt . Zur Realisierung dieser Funktion wird über eine Hand betätigte Mechanik in Form eines Betätigungselements, eines Schaltschlosses und einer Betätigungskette, der Kontaktapparat aus Kontaktschieber und einer beweglichen Brücke freigegeben. Die Freigabe erfolgt durch eine so genannte Schnelleinschaltung, die präzisiert formuliert eine spontane oder sprunghafte Einschaltung ist. Dabei werden die drei Kontaktsysteme durch eine Mechanik erst dann freigegeben, nachdem das Schaltschloss bereits eingeschaltet wurde. Nun bestimmt der Federspeicher in Form einer Kontaktlastfeder die Kinematik des Kontaktsystems beim Einschalten. closes. To realize this function is released via a hand-operated mechanism in the form of an actuating element, a switching mechanism and an actuating chain, the contact mechanism of contact slide and a movable bridge. The release takes place by means of a so-called quick turn-on, which, more precisely stated, is a spontaneous or erratic activation. The three contact systems are released by a mechanism only after the switch lock has already been turned on. Now, the spring-loaded in the form of a contact load spring determines the kinematics of the contact system when switching.
Nach dem Auftreffen der Brücken auf den Festschaltstücken beschleunigt der Kontaktschieber, bis er an einem Anschlag reflektiert wird. Durch die Reflexion und der daraus resultierenden kinetischen Energie des Kontaktschiebers kommt es zu einem erneuten Öffnen des Kontaktsystems. Dies kann bei einem gleichzeitig erhöhten Strom in dieser Strombahn zu Verschweißungen führen . After striking the bridges on the Festschaltstücken the contact slide accelerates until it is reflected at a stop. The reflection and the resulting kinetic energy of the contact slide reopen the contact system. This can lead to welds with a simultaneously increased current in this current path.
Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, ein Schaltgerät mit einer Einrichtung zum sprunghaften Einschalten zu schaffen, die ein Kontaktabheben mit möglicher Kontaktverschweißung vermeidet. Accordingly, the object of the present invention is to provide a switching device with a device for sudden switching, which avoids a contact lift with possible contact welding.
Diese Aufgabe wird erfindungsgemäß durch ein Schaltgerät mit den Merkmalen des Patentanspruchs 1 gelöst. Weitere Ausführungsbeispiele der Erfindung ergeben sich aus den Unteransprüchen, der Beschreibung sowie der Zeichnung. This object is achieved by a switching device with the features of claim 1. Further embodiments of the invention will become apparent from the dependent claims, the description and the drawings.
Erfindungsgemäß wird diese Aufgabe durch ein Schaltgerät mit einer Einrichtung zum sprunghaften Einschalten gelöst, die eine Betätigungsmechanik aufweist, die ein Betätigungselement aufweist und über eine Übertragungsmechanik mit einem Schaltschloss in Wirkverbindung steht, welches über eine weitere Übertragungsmechanik einen Schalthebel bedient, und eine Kontaktanordnung aufweist, die ein festes Schaltstück mit Kon- takten aufweist, welches gegenüber liegend zu einem beweglichen Schaltstück mit Kontakten angeordnet ist, welches in ei nem Kontaktschieber geführt ist. Die Erfindung zeichnet sich dabei dadurch aus, dass die Einrichtung zum sprunghaften Ein schalten einen im Schaltschloss angeordneten Hebel aufweist, der in Wirkverbindung zu einem Sperrteil angeordnet ist, das in Wirkverbindung zu einem Übertragungsglied steht, das auf das bewegliche Schaltstück der Kontaktanordnung wirkt. According to the invention, this object is achieved by a switching device with a device for sudden switching, which has an actuating mechanism which has an actuating element and is operatively connected via a transmission mechanism with a switch lock, which operates a shift lever via a further transmission mechanism, and has a contact arrangement which a fixed contact piece with con- has clocks, which is arranged opposite to a movable contact piece with contacts, which is guided in egg NEM contact slide. The invention is characterized in that the means for jumping A switch has arranged in a switch lock lever which is arranged in operative connection to a blocking part, which is in operative connection to a transmission member which acts on the movable contact piece of the contact arrangement.
Bei einem dreipoligen Schaltgerät, insbesondere bei einem Leistungsschalter, werden die drei Kontaktapparate aus beweg liehen und festen Schaltstücken über einen fingerförmigen Schalthebel in die ausgeschaltete Stellung gedrückt. Damit verbunden ist ein definierter Abstand a der beweglichen und festen Schaltstücke voneinander. Beim Betätigen des Bedienelements beginnt das Schaltschloss über dessen Hebel, welche eine Drehbewegung erfährt, das Übertragungsglied und somit den Kontaktapparat freizugeben. Nach einem Vorlauf zwingt de Hebel das Sperrteil seiner Drehbewegung zu folgen, da beide Teile den gleichen Lagerpunkt besitzen. Nach dem Durchlaufen des Drehwinkels blockiert das Sperrteil das Übertragungsglied, so dass der Kontaktabstand zwischen beweglichem In a three-pole switching device, in particular at a circuit breaker, the three contact devices from moving lent and fixed contact pieces are pressed via a finger-shaped lever in the off position. This is associated with a defined distance a of the movable and fixed contact pieces from each other. When the operating element is actuated, the switch lock begins to release the transmission element and thus the contact apparatus via its lever, which undergoes a rotational movement. After a forward de lever forces the locking part to follow its rotational movement, since both parts have the same bearing point. After passing through the rotation angle, the locking member blocks the transmission member, so that the contact distance between movable
Schaltstück und festem Schaltstück nun den Abstand b einhält Der Abstand b wird so lange konstant gehalten, bis das Sperr teil den Abstand c am Übertragungsglied durchlaufen hat. Wäh rend das Übertragungsglied den Kontaktapparat blockiert, führt der Hebel seine Drehbewegung fort. Nach Durchlauf des Abstands c wird das Übertragungsglied freigegeben, so dass der Kontaktapparat unabhängig von der Drehbewegung des Bedienteils die Strombahn schließen kann. Durch die Zwangsführung des Sperrteils am Schalthebel erfolgt eine konstante Freigabe des Übertragungsglieds. Switching piece and fixed contact now the distance b complies with the distance b is kept constant until the blocking part has passed through the distance c on the transmission member. While the transmission member blocks the contactor, the lever continues to rotate. After passage of the distance c, the transmission member is released, so that the contact apparatus can close the current path independently of the rotational movement of the operating part. Due to the positive guidance of the locking part on the shift lever is a constant release of the transmission element.
Der Kern der Erfindung besteht darin, dass der Einschaltvorgang unabhängig von der Drehbewegung am Bedienteil erfolgt. Der Abstand c bestimmt die Zeit, für welche der Kontaktabstand b gehalten wird. Während dieser Zeitspanne wird das Be dienteil in die eingeschaltete Position gebracht, so dass di Schließung der Strombahn nicht durch die Drehbewegung am Bedienteil, sondern durch die Dynamik des Kontaktapparats und dessen Kontaktlastfeder bestimmt wird. Dies führt im Weiteren dazu, dass es keine zeitliche Abweichung beim Schließen der einzelnen Strombahnen untereinander gibt. Durch die spontane bzw. sprunghafte Einschaltung bestimmen die Kontaktlastfedern die Dynamik der beweglichen Schaltstücke und nicht die Drehbewegung des Bedienteils. Durch das enge Toleranzband der Kontaktlastfeder, dem annähernd konstanten Gewicht der Brücken sowie des Kontaktschiebers, erfolgt ein nahezu gleichzeitiges Schließen der Strombahn. Dadurch können Lichtbögen und Verschweißungen vermieden werden. Daraus resultiert eine Erhöhung des Einschaltbemessungsstroms . Die Zwangsführung zwischen Hebel und Sperrteil führt zu einem konstanten zeitlichen Ablauf des Einschaltvorgangs und zu einer kleinen Toleranzkette und somit zu einer hohen Genauigkeit für den Abstand b. Das jeweilige Schaltgerät kann gerätespezifisch mit einem entsprechenden Sperrteil bestückt werden. The essence of the invention is that the switch-on takes place independently of the rotational movement on the control panel. The distance c determines the time for which the contact distance b is maintained. During this period, the loading is beeileil in the on position, so that the di Closure of the current path is not determined by the rotational movement on the control panel, but by the dynamics of the contact apparatus and its contact load spring. This leads to the fact that there is no time difference when closing the individual current paths with each other. Due to the spontaneous or sudden activation, the contact load springs determine the dynamics of the movable contact pieces and not the rotary movement of the operating unit. Due to the close tolerance band of the contact load spring, the approximately constant weight of the bridges and the contact slide, there is an almost simultaneous closing of the flow path. As a result, arcing and welding can be avoided. This results in an increase of the switch-on rated current. The positive guidance between lever and locking part leads to a constant timing of the switch-on and to a small tolerance chain and thus to a high accuracy for the distance b. The respective switching device can be equipped device-specific with a corresponding locking part.

Das erfindungsgemäße Sperrteil weist ein keilförmiges Bauteil auf, aus welchem vorzugsweise zur gleichen Seite vorzugsweise zwei Schenkel herausragen, wobei der eine Schenkel eine The blocking part according to the invention has a wedge-shaped component, from which preferably two limbs preferably protrude to the same side, wherein one limb forms a limb
Durchbohrung aufweist und leicht gerundet ausgebildet ist, und der andere Schenkel vollflächig und leicht keilförmig ausgebildet ist. An der Spitze des vollflächigen Schenkels ist ein vorzugsweise halbkonzentrischer Vorsprung angeordnet. Das Sperrteil wird am Hebel positioniert, in dem die Durchbohrung des Schenkels vom Sperrteil auf der Durchbohrung des kleinen Schenkels des Hebels positioniert wird, so dass Hebel und Sperrteil im gleichen Lagerpunkt gelagert sind. Durch diese gleiche Lagerung ist der vollflächige Schenkel des Sperrteils unterhalb des vollflächigen Schenkels des Hebels positioniert . Having perforated and slightly rounded is formed, and the other leg is formed over its entire surface and slightly wedge-shaped.

By this same storage of the full-surface leg of the locking member is positioned below the full-surface leg of the lever.
Das erfindungsgemäße Übertragungsglied weist eine vorzugsweise nahezu ebene Rückwandfläche auf, aus welcher zur gleichen Seite zwei Seitenwandungen herausragen. Die Seitenwandungen weisen jeweils einen parallel zueinander und voneinander be- abstandeten Bereich auf und einen zulaufenden Bereich, in welchem die Seitenwandungen aufeinander zulaufend ausgebildet sind. Am Übergang zwischen dem parallel ausgebildeten Bereich der Seitenwandung und dem zulaufenden Bereich der Seitenwandung ist ein Verbindungssteg ausgebildet. Der zulaufende Bereich der Seitenwandung mündet in zwei kürzere, parallel zueinander angeordnete Schenkel und zwei längere, parallel zueinander angeordnete Schenkel, die jeweils voneinander beabstandet sind und unterhalb vom Verbindungssteg angeordnet sind und im Schaltgerät zur Kontaktanordnung hin ausgebildet sind . The transmission element according to the invention has a preferably almost flat rear wall surface, from which two side walls protrude to the same side.

Dabei ist eine der beiden parallelen Seitenwandungen kleiner als die andere ausgeführt und weist eine abgeschrägte Fläche auf, die im Schaltgerät in Wirkverbindung mit dem keilförmigen Bauteil des Sperrteils steht. Die Spitze des keilförmigen Bauteils des Sperrteils zieht über die abgeschrägte Fläche der Seitenwandung des Übertragungsglieds hinweg, bis sie in der eingeschalteten Position des Schaltgeräts mit der Rückseite des vollflächigen Schenkels des Sperrteils auf der abgeschrägten Fläche der Seitenwandung des Übertragungsglieds zu liegen kommt. The mutually parallel regions of the side wall are arranged above the connecting web in the direction of the switching mechanism. In this case, one of the two parallel side walls is smaller than the other and has a bevelled surface, which is in the switching device in operative connection with the wedge-shaped component of the blocking part.

In Fig. 19 ist das Schaltschloss 32 dargestellt, welches auf den Schalthebel 36 wirkt und zwar in der Art, dass der In Fig. 18, the switching mechanism 32 of the switching device, which is operatively connected to the device according to the invention for sudden switching, and a contact arrangement in the on position shown. In the switched-on position, the movable contact piece 34 is now on the fixed contact piece 33. It can be seen from Fig. 18 further that the lever 1 has completed a further rotational movement, by which the locking member 12 has been rotated further. By the rotational movement of the locking member 12 is now the back of the leg 15 of the locking member 12 on the chamfered surface 31 of the transmission member 18th In Fig. 19, the switching mechanism 32 is shown, which acts on the shift lever 36 in such a way that the
Schalthebel 36 nun keinen Schalthebelberührungspunkt mehr mit dem Kontaktschieber aufweist. Das bewegliche Schaltstück 34 liegt nun auf dem festen Schaltstück 33 auf. Shift lever 36 now has no Schalthebelberührungspunkt more with the contact slide. The movable contact piece 34 is now on the fixed contact 33.
Fig. 20 zeigt die erfindungsgemäße Einrichtung zum sprunghaften Einschalten mit Kontaktanordnung in einer schematischen Darstellung. Aus dieser Fig. 20 kann entnommen werden, dass die weitere Drehbewegung des Sperrteils 12 nun dazu führt, dass das Sperrteil 12 in der eingeschalteten Position hinter der abgeschrägten Fläche 31 angeordnet ist. Fig. 20 shows the inventive device for sudden switching with contact arrangement in a schematic representation. From this Fig. 20 it can be seen that the further rotational movement of the locking member 12 now causes the locking member 12 is disposed in the on position behind the chamfered surface 31.
Die Erfindung zeichnet sich dadurch aus, dass der Einschaltvorgang unabhängig von der Drehbewegung am Bedienteil erfolgt. Durch die sprunghafte Einschaltung bestimmen die Kontaktlastfedern die Dynamik der beweglichen Schaltstücke und nicht die Drehbewegung des Bedienteils. Durch das enge Toleranzband der Kontaktlastfeder , dem annähernd konstanten Gewicht der Brücken sowie des Kontaktschiebers, erfolgt ein nahezu gleichzeitiges Schließen der Strombahnen. Dadurch können Lichtbögen und Verschweißungen vermieden werden. Die erfindungsgemäße Zwangsführung zwischen Hebel und Sperrteil führt zu einem konstanten zeitlichen Ablauf des Einschaltvorgangs und zu einer kleinen Toleranzkette. Das erfindungsgemäße Sperrteil kann gerätespezifisch ausgelegt werden. The invention is characterized in that the switch-on takes place independently of the rotational movement on the control panel. Due to the sudden start, the contact load springs determine the dynamics of the moving contact pieces and not the rotation of the operating unit. Due to the close tolerance band of the contact load spring, the approximately constant weight of the bridges and the contact slide, there is an almost simultaneous closing of the current paths. As a result, arcing and welding can be avoided. The positive guidance according to the invention between lever and locking part leads to a constant time sequence of the switch-on process and to a small tolerance chain. The blocking part according to the invention can be designed device-specific.
