Description

Beschreibungdescription
Modulares SchaltgerätModular switching device
Die Erfindung bezieht sich auf ein modulares Schaltgerät nach dem Oberbegriff des Anspruchs 1.The invention relates to a modular switching device according to the preamble of claim 1.
Die Einsatzfähigkeit eines (Niederspannungs-) Schaltgeräts wird allgemein von der so genannten elektrischen Lebensdauer begrenzt. Das Ende der elektrischen Lebensdauer ist erreicht, wenn das Kontaktmaterial an den Schaltstücken des Schaltgeräts vollständig verbraucht ist oder wenn feste und bewegliche Schaltstücke miteinander verschweißen. Der Verbrauch an Kontaktmaterial richtet sich bei einem Schütz nach der ge- schalteten Last. Bei einem Leistungsschalter wird die elektrische Lebensdauer vor allem durch die Höhe des abgeschalteten Kurzschlussstroms bestimmt.The operational capability of a (low-voltage) switching device is generally limited by the so-called electrical life. The end of the electrical life is reached when the contact material is completely consumed at the switching pieces of the switching device or when solid and movable contact pieces weld together. The consumption of contact material depends on a contactor after the switched load. For a circuit breaker, the electrical life is mainly determined by the level of the short-circuit current cut off.
Zumal die mechanische Lebensdauer bei einem Schaltgerät übli- cherweise weit über der elektrischen Lebensdauer liegt, können bei Schützen großer Baugrößen die beweglichen und die festen Schaltstücke häufig einzeln ausgetauscht werden, so dass die restlichen Bestandteile des Schaltgeräts über den Zeitraum der elektrischen Lebensdauer hinaus weiterverwendet werden können. Der Austausch der Schaltstücke ist aber vergleichsweise aufwändig. Bei klein dimensionierten Schaltgeräten ist daher in der Regel keine Austauschmöglichkeit vorgesehen. Diese Schaltgeräte müssen nach Ablauf der elektrischen Lebensdauer im Ganzen ausgetauscht werden.In addition, since the mechanical life of a switching device is usually much higher than the electrical life, in the case of large-size contactors, the moving and fixed contact pieces can often be replaced individually, so that the remaining components of the switching device can continue to be used beyond the period of electrical life , The replacement of the switching pieces but is relatively expensive. For small sized switching devices therefore no exchange option is usually provided. These switchgear must be replaced at the end of the electrical life as a whole.
Andererseits sind, z.B. aus der DE 35 31 710 C2, der EP 0 179 677 Al sowie der DE 198 36 549 Al, modular aufgebaute Schaltgeräte bekannt. Durch den modularen Aufbau soll bei diesen Schaltgeräten ein hoher Vorfertigungsgrad erreicht werden, d.h. die Möglichkeit geschaffen werden, durch variable Kombination einer Schaltkammer mit unterschiedlichen Funktionsmodulen eine Vielzahl von Gerätevarianten unterschiedlicher Funktionalität zusammensetzen zu können. Eine abnehmbare Be- festigung der Funktionsmodule an der Schaltkammer ist aus den letztgenannten Dokumenten nicht zu entnehmen.On the other hand, for example, from DE 35 31 710 C2, EP 0 179 677 Al and DE 198 36 549 Al, modular switchgear known. Due to the modular structure, a high degree of prefabrication is to be achieved in these switching devices, ie the possibility is created to be able to assemble a variety of device variants of different functionality by a variable combination of a switching chamber with different functional modules. A removable cover consolidation of the functional modules at the switching chamber is not apparent from the latter documents.
Ein Schaltgerät gemäß dem Oberbegriff des Anspruchs 1 ist aus der DE 689 06 238 T2 bekannt. Das dortige Schaltgerät umfasst eine Schaltkammer mit einem mehrpoligen Leistungsschalter zum Schalten der Stromleitungen einer Hauptstrombahn. Das bekannte Schaltgerät umfasst weiterhin zwei Betätigungsmodule, die - zum Auswechseln dieser Module, insbesondere bei schaltungs- technisch montierter Schaltkammer - abnehmbar sind, und die elektro-mechanische Komponenten zur direkten Betätigung bzw. indirekten Betätigung des Leistungsschalters enthalten. Dem indirekten Betätigungsmodul sind hierbei Schutzvorrichtungen zugeordnet, die bei Nachweis einer Anomalie des in der Haupt- strombahn fließenden Stroms ein Schaltschloss betätigen, welches wiederum zur Unterbrechung der Hauptstrombahn auf den Leistungsschalter wirkt. Die Schutzvorrichtungen sind über Kontaktstifte und korrespondierende Kontakthülsen elektrisch mit den Stromleitungen der Hauptstrombahn kontaktiert, so dass die Hauptstrombahn aus der Schaltkammer in zumindest eines der Betätigungsmodule hineingeführt ist.A switching device according to the preamble of claim 1 is known from DE 689 06 238 T2. The local switching device comprises a switching chamber with a multi-pole circuit breaker for switching the power lines of a main flow path. The known switching device further comprises two actuation modules, which are removable for exchanging these modules, in particular in switching-technically mounted switching chamber, and which contain electro-mechanical components for direct actuation or indirect actuation of the circuit breaker. In this case, protective devices are associated with the indirect actuation module which, upon detection of an anomaly of the current flowing in the main flow path, actuate a switch lock, which in turn acts to interrupt the main flow path to the circuit breaker. The protective devices are electrically contacted via contact pins and corresponding contact sleeves with the power lines of the main flow path, so that the main flow path from the switching chamber is guided into at least one of the actuation modules.
Der Erfindung liegt die Aufgabe zugrunde, ein Schaltgerät anzugeben, das auf einfache Weise zumindestens teilweise über die gewöhnliche elektrische Lebensdauer hinaus einsetzbar ist.The invention has for its object to provide a switching device that can be used in a simple manner at least partially beyond the usual electrical life out.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Danach ist das Schaltgerät modular aufgebaut und umfasst eine Schaltkammer, die neben einer Schalteinheit alle Komponenten einer dieser Schalteinheit zugeordneten Hauptstrombahn enthält. Das Schaltgerät umfasst weiterhin ein Basismodul, das eine mechanisch und/oder elektrisch (und damit optional auch elektro-mechanisch oder elektronisch) an- steuerbare Auslösemechanik zur Betätigung der Schalteinheit umfasst. Die Schaltkammer und das Basismodul sind hierbei (zerstörungsfrei) abnehmbar aneinander befestigt, so dass nach Ende der elektrischen Lebensdauer die verbrauchte Schaltkammer mit geringem Aufwand gegen eine neue Schaltkammer ausgetauscht werden kann, und somit das verbleibende Basismodul über den Zeitraum der elektrischen Lebensdauer hinaus weiterverwendbar ist.This object is achieved by the features of claim 1. Thereafter, the switching device is modular and includes a switching chamber containing all the components of a switching unit associated with this main circuit in addition to a switching unit. The switching device further comprises a base module which comprises a mechanically and / or electrically (and thus optionally also electro-mechanically or electronically) controllable triggering mechanism for actuating the switching unit. The switching chamber and the base module are in this case (non-destructive) removably attached to each other, so that after the end of the electrical life of the consumed Switching chamber can be replaced with little effort against a new switching chamber, and thus the remaining base module over the period of electrical life is also reusable.
Die Erfindung greift hiermit das Konzept eines modular aufgebauten Schaltgeräts wieder auf. Der Einsatz der modularen Bauweise erfolgt hier aber vor einem anderen Hintergrund als im Stand der Technik, insbesondere zur Lösung einer Aufgabe, die bei der Konzeption der vorbekannten modularen Schaltgeräte keine Rolle spielte. Im Stand der Technik erfolgt der Einsatz der modularen Bauweise zur Erzielung einer variablen Funktionalität durch Kombination der Schaltkammer mit verschiedenartigen Funktionsmodulen.The invention again takes up the concept of a modular switching device. However, the use of the modular construction takes place here before a different background than in the prior art, in particular for solving a task that played no role in the design of the prior art modular switching devices. In the prior art, the use of the modular design to achieve a variable functionality by combining the switching chamber with different types of functional modules.
Die erfindungsgemäß erreichte Austauschbarkeit der Schaltkammer wird demgegenüber insbesondere durch die Kombination zweier Merkmale erzielt, die erst vor dem anmeldungsgemäßen Hintergrund synergetisch zusammenwirken, nämlich einerseits die abnehmbare Befestigung der Schaltkammer an dem Basisgerät, die einen Austausch der ersteren erst ermöglicht, und andererseits die ausschließliche Anordnung der Hauptstrombahn innerhalb der Schaltkammer, ohne die ein Austausch der letzteren im Hinblick auf die Verwendbarkeit des Schaltgeräts letztlich wirkungslos wäre.The interchangeability of the switching chamber achieved according to the invention is achieved in particular by the combination of two features that synergize only before the background according to the application, namely on the one hand, the removable attachment of the switching chamber to the base unit, which allows an exchange of the former, and on the other hand, the exclusive arrangement of Main flow path within the switching chamber without which an exchange of the latter in terms of the usability of the switching device would ultimately be ineffective.

Dieses Messsignal ist der Auswerteelektronik über einen elektrischen Signal- kreis, d.h. über einen von der Hauptstrombahn getrennten Sekundärstromkreis, zugeführt. Durch die Auslöseelektronik wird das Messsignal im Hinblick auf eine Auslösebedingung analysiert, wobei die Auswerteelektronik den Antrieb ansteuert, wenn die Auslösebedingung erfüllt ist. Je nach Art des zuge- führten Messsignals und Vorgabe der Auslösebedingung kann die elektronische Schutzschalteinheit zur Erkennung von Überlast, Kurzschluss, Leitungsbruch, Unter- oder Überspannung oder anderen Anomalien des in der Hauptstrombahn fließenden Stroms ausgebildet sein.

To ensure easy interchangeability of the switching chamber, the measuring unit is in the

Weiterhin sind zweckmäßigerweise der Wandler und der Lastdetektor - sofern vorgesehen - mehrpolig ausgeführt oder in einer der Polzahl entsprechenden Anzahl mehrfach vorhanden.In a preferred embodiment, the switching device is multi-pole, designed in particular three-pole. In this embodiment, the main flow path comprises a number of individual lines corresponding to the number of poles. Likewise, the switching unit comprises a number of individual switches corresponding to the number of poles, one of which is assigned to a single line. Furthermore, expediently, the converter and the load detector - if provided - designed to be multi-pole or multiply in a number corresponding to the number of poles.
Zur Aufnahme jeweils einer Einzelleitung und des zugehörigen Einzelschalters ist die Schaltkammer in eine der Polzahl entsprechende Anzahl von Polkammern aufgeteilt, die insbesondere durch Längswände voneinander getrennt sind. Die Einzelschalter der Schalteinheit können innerhalb der Schaltkammer mechanisch miteinander verbunden sein. Vorzugweise ist aber der Bewegkontakt eines jeden Einzelschalters mechanisch für sich isoliert gelagert. Die Auslösemechanik ist hierbei derart ausgebildet, dass im bestimmungsgemäßen Betrieb alle Einzelschalter simultan betätigt werden.For receiving in each case a single line and the associated individual switch, the switching chamber is divided into a number of poles corresponding number of Polkammern, which are separated from each other in particular by longitudinal walls. The individual switches of the switching unit can be mechanically connected to each other within the switching chamber. Preferably, however, the moving contact of each individual switch is mechanically isolated for itself. The release mechanism is in this case designed such that all individual switches are operated simultaneously during normal operation.
Die Schaltkammer und das Basismodul sind insbesondere miteinander verschraubt oder lösbar miteinander verrastet. Im Hinblick auf die Austauschbarkeit der Schaltkammer ist es hierbei von Vorteil, wenn die hierzu vorgesehenen Befestigungsmittel in Fügerichtung wirken, so dass zum Verbinden und Trennen der Schaltkammer und des Basismoduls incl. deren gegenseitiger Befestigung lediglich eine unidirektionaler Steckbewegung erforderlich ist. Vorzugsweise sind die Befestigungsmittel (z.B. also die Schrauben oder Rasthaken) zum Lösen der Verbindung zwischen der Sehaltkämmer und dem Basisgerät nur von dem Boden der Schaltkammer her zugänglich. Dies erhöht die Betriebssicherheit des Schaltgerätes, zumal der Boden der Schaltkammer bei eingebautem Schaltgerät üblicher- weise nicht zugänglich ist. Die Verbindung zwischen dem Basismodul und der Schaltkammer kann daher nur bei abmontiertem Schaltgerät gelöst werden.The switching chamber and the base module are in particular screwed together or releasably locked together. With regard to the interchangeability of the switching chamber, it is advantageous in this case if the fastening means provided for this purpose act in the joining direction, so that only a unidirectional plugging movement is required for connecting and disconnecting the switching chamber and the base module, including their mutual fastening. Preferably, the fastening means (eg, the screws or latching hooks) for Release the connection between the Sehaltkämmer and the base unit accessible only from the bottom of the switching chamber ago. This increases the reliability of the switching device, especially since the bottom of the switching chamber is usually not accessible when the switching device is installed. The connection between the base module and the switching chamber can therefore be solved only when dismantled switching device.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Darin zeigen:An embodiment of the invention will be explained in more detail with reference to a drawing. Show:

Einander entsprechende Teile und Größen sind in allen Figuren stets mit den gleichen Bezugszeichen versehen.Corresponding parts and sizes are always provided with the same reference numerals in all figures.
Das in FIG 1 dargestellte Schaltgerät 1 umfasst eine Schaltkammer 2 sowie ein auf dieses aufsetzbares Basismodul 3. Die Schaltkammer 2 und das Basismodul 3 sind hierbei über Befestigungsschrauben 4, die von der von dem Basismodul 3 abge- wandten Unterseite 5 der Schaltkammer 2 her betätigbar sind, aneinander zu befestigen, wobei diese Schraubverbindung zum Auswechseln der Schaltkammer 2 zerstörungsfrei lösbar ist, um das Basismodul 3 mit ausgetauschter Schaltkammer 2 erneut zu verwenden.The switching device 1 illustrated in FIG. 1 comprises a switching chamber 2 and a base module 3 which can be placed thereon. The switching chamber 2 and the base module 3 are in this case via fastening screws 4, which can be actuated by the underside 5 of the switching chamber 2 facing away from the base module 3 to attach to each other, this screw for replacing the switching chamber 2 is non-destructive solvable to reuse the base module 3 with exchanged switching chamber 2.
Das Schaltgerät 1 ist dreipolig ausgeführt und umfasst eine Hauptstrombahn 6, die entsprechend der Polzahl in drei Einzelleitungen 7 aufgeteilt ist. Jede Einzelleitung 7 dient zur Leitung eines Stroms zwischen einer ersten Anschlussklemme 8 und einer zweiten Anschlussklemme 9. Die Hauptstrombahn 6 enthält innerhalb einer jeder ihrer Einzelleitungen 7 jeweils einen elektro-mechanischen Lastdetektor 10 und jeweils einen als Strom- oder Spannungsmesseinheit ausgebildeten Wandler 11. Die Hauptstrombahn 6 umfasst weiterhin eine Schalteinheit 12 mit drei Einzelschaltern 13, von denen jeweils einer in eine jede Einzelleitung 7 geschaltet ist.The switching device 1 is designed in three poles and comprises a main current path 6, which is divided into three individual lines 7 according to the number of poles. Each individual line 7 serves to conduct a current between a first terminal 8 and a second terminal 9. The main current path 6 contains within each of its individual lines 7 each an electro-mechanical load detector 10 and each designed as a current or voltage measuring unit converter 11. The main flow path 6 further comprises a switching unit 12 with three individual switches 13, one of which is connected in each individual line 7 in each case.
Die Hauptstrombahn 6 ist einschließlich aller ihrer Komponenten in der Schaltkammer 2 angeordnet. Hierbei ist jeder Einzelleitung 7 innerhalb der Schaltkammer 2 eine eigene Polkammer 14 zugeordnet, wobei angrenzende Polkammern 14 durch Längswände 15 der Schaltkammer 2 voneinander abgetrennt sind.The main flow path 6 is arranged including all its components in the switching chamber 2. Here, each individual line 7 within the switching chamber 2 is associated with its own pole chamber 14, wherein adjacent pole chambers 14 are separated by longitudinal walls 15 of the switching chamber 2 from each other.
FIG 2 zeigt den Aufbau der Hauptstrombahn 6 am Beispiel einer Einzelleitung 7 in schematischer Darstellung. Wie aus dieser Darstellung insbesondere erkennbar ist, umfasst jeder Einzelschalter 13 (in an sich herkömmlicher Art und Weise) zwei einander beabstandet gegenüberliegende Festschaltstücke 16, von denen einer mit der Anschlussklemme 8 und der andere mit der Anschlussklemme 9 verbunden ist, und die mittels einer Kontaktbrücke 17 leitend überbrückbar sind. Die Kontaktbrücke 17 umfasst hierzu zwei leitend verbundene Gegenschaltstücke 18, von denen jedes mit einem Festschaltstück 16 korrespondiert und die an einem gemeinsamen Mittelblock 19 befestigt sind. Der Mittelblock 19 ist derart gegen Federdruck auslenkbar, dass in einer Ruhestellung des Mittelbl'ocks 19 die Festschaltstücke 16 mit den jeweiligen Gegenschaltstücken 18 kon- taktieren, und dass bei Auslenkung des Mittelblocks 19 aus der Ruhestellung beide Gegenschaltstücke 18 gleichzeitig von den Festschaltstücken 16 getrennt werden.2 shows the structure of the main flow path 6 using the example of a single line 7 in a schematic representation. As can be seen in particular from this illustration, each individual switch 13 comprises (in a conventional manner) two spaced-apart fixed switching pieces 16, one of which is connected to the terminal 8 and the other to the terminal 9, and by means of a contact bridge 17 are conductible bridged. For this purpose, the contact bridge 17 comprises two oppositely connected counter-switching pieces 18, each of which corresponds to a fixed switching piece 16 and which are fastened to a common middle block 19. The center block 19 is such against spring pressure deflectable, that the fixed contact pieces 16 taktieren in a rest position of Mittelbl 'ocks 19 with the respective counter-contact pieces 18 con-, and that separated upon deflection of the center block 19 from the rest position to both contact pieces 18 at the same time from the fixed contact members 16 ,
Um einen bei diesem Schaltvorgang entstehenden Schaltlicht- bogen schnell zum Erlöschen zu bringen, ist jedem Festschaltstück 16 ein Löschblechpaket 20 beigeordnet.In order to rapidly cancel a shift arc resulting in this shift operation, each firing piece 16 is assigned a splitter stack 20.
Das Basismodul 3 enthält, wie ebenfalls aus FIG 2 ersichtlich ist, eine Schaltmechanik 21 zur simultanen Betätigung der Einzelschalter 13 der Schalteinheit 12. Die Schaltmechanik 21 umfasst ein Schaltschloss 22, das über einen Stößel 23 auf die Schalteinheit 12 wirkt. Das Schaltschloss 22 ist einerseits mittels eines Betätigungsknopfes 24, der an einer von der Schaltkammer 2 abgewandten Oberseite 25 aus dem Gehäuse des Basismoduls 3 herausragt, manuell betätigbar.The base module 3 includes, as also shown in FIG 2, a switching mechanism 21 for simultaneous operation of the individual switch 13 of the switching unit 12. The switching mechanism 21 comprises a switching mechanism 22 which acts on the switching unit 12 via a plunger 23. The switching mechanism 22 is on the one hand by means of an actuating knob 24 which is connected to one of the switching chamber 2 facing away from the upper side 25 protrudes from the housing of the base module 3, manually operable.
Die Schaltmechanik 21 umfasst weiterhin einen elektromagneti- sehen Antrieb 26, der über ein Umlenkglied 27 und einen Stößel 28 auf die Schalteinheit 12 wirkt. Der Antrieb 26 ist ü- ber eine elektrische Steuerleitung 29 von außen ansteuerbar. Insbesondere ist der Antrieb 26 dabei derart ausgeführt, dass er die Schalteinheit 12 freigibt, solange über die Steuerlei- tung 29 eine von Null verschiedene Steuerspannung U zugeführt wird, und dass er die Schalteinheit 12 betätigt (und damit die Hauptstrombahn 6 unterbricht) , sobald die über die Steuerleitung 29 zugeführte Steuerspannung U zusammenbricht.The switching mechanism 21 further comprises an electromagnetic drive 26, which acts on the switching unit 12 via a deflecting member 27 and a plunger 28. The drive 26 can be controlled via an electrical control line 29 from the outside. In particular, the drive 26 is designed such that it releases the switching unit 12 as long as a non-zero control voltage U is supplied via the control line 29, and that it actuates the switching unit 12 (and thus interrupts the main flow path 6) as soon as the via the control line 29 supplied control voltage U collapses.
Dem Schaltgerät 1 sind weiterhin zwei Schutzschalteinheiten 30,31 zugeordnet. Die erste Schutzschalteinheit 30 umfasst den Wandler 11 sowie eine in dem Basismodul 3 angeordnete Auswerteelektronik 32. Der Wandler 11 und die Auswerteelektronik 32 sind über einen von der Hauptstrombahn 6 galvanisch getrennten Signalkreis 33 verbunden, der an der Schnittstelle zwischen der Schaltkammer 2 und dem Basismodul 3 über einen Steckkontakt 34 geschlossen ist. Im Betrieb des Schaltgeräts 1 liefert der Wandler 11 über den Signalkreis 33 ein Messsignal M in Form einer Kleinspannung an die Auswerteelektro- nik 32, das den durch die Einzelleitung 7 fließenden Strom oder die zugehörige Spannung wiederspiegelt. Die Auswerteelektronik 32 analysiert das Messsignal M auf das Vorliegen einer vorgegebenen Auslösebedingung (z.B. Kurzschluss, Überlast, Unterspannung, Überspannung, etc.) und steuert den An- trieb 26 bei Vorliegen dieser Auslösebedingung derart an, dass dieser die Schalteinheit 12 betätigt und die Hauptstrombahn 6 unterbricht.The switching device 1 are further assigned two protection switching units 30,31. The first protective switching unit 30 comprises the converter 11 and an evaluation electronics 32 arranged in the base module 3. The converter 11 and the evaluation electronics 32 are connected via a signal circuit 33 which is galvanically isolated from the main current path 6 and which is connected to the interface between the switching chamber 2 and the base module 3 is closed via a plug contact 34. During operation of the switching device 1, the converter 11 supplies via the signal circuit 33 a measurement signal M in the form of a low voltage to the evaluation electronics 32, which reflects the current flowing through the individual line 7 or the associated voltage. The evaluation electronics 32 analyzes the measurement signal M for the presence of a predetermined triggering condition (eg short circuit, overload, undervoltage, overvoltage, etc.) and controls the drive 26 in the presence of this triggering condition such that it actuates the switching unit 12 and the main current path 6 interrupts.
Diese Funktionalität ist schaltungstechnisch besonders ein- fach realisiert, indem die Auswerteelektronik 32 nach Art eines Schalters in die Steuerleitung 29 geschaltet ist und diese bei Vorliegen der Auslösebedingung unterbricht, wodurch die Steuerspannung U zwangsweise zum Erliegen kommt und der Antrieb 26 auslöst.This functionality is realized in a particularly simple manner in terms of circuitry, in that the evaluation electronics 32 are connected in the manner of a switch in the control line 29 and interrupts them in the presence of the triggering condition, whereby the control voltage U forcibly comes to a halt and the drive 26 triggers.
Die zweite Schutzschalteinheit 31 umfasst den Wandler 10 so- wie ein nach Art einer schwenkbaren Wippe ausgebildetes mechanisches Übermittlungsglied 35. Das Übermittlungsglied 35 ist hierbei derart in dem Basismodul 35 schwenkbar gelagert, dass ein Freiende 36 des Übermittlungsglieds 35 im Montagezustand des Schaltgeräts 1 mit einem Auslösestift 37 des Wandlers 10 lose verklinkt ist, so dass das Übermittlungsglied 35 im Montagezustand mit dem Wandler 10 bewegungsmäßig gekoppelt ist. Das entgegengesetzte Freiende 38 des Betätigungsglieds 35 wirkt mit dem Schaltschloss 22 zusammen.The second protection switching unit 31 comprises the transducer 10 and a mechanical transmission element 35 designed in the manner of a pivotable rocker. The transmission element 35 is pivotably mounted in the base module 35 such that a free end 36 of the transmission element 35 in the assembled state of the switching device 1 with a release pin 37 of the transducer 10 is loosely latched, so that the transmission member 35 is coupled in the assembled state with the transducer 10 in terms of movement. The opposite free end 38 of the actuator 35 cooperates with the switching mechanism 22.
Der Lastdetektor 10 ist durch eine Spulenwicklung der Einzelleitung 7 gebildet, in der der Auslösestift 37 axialbeweglich geführt ist. Der Lastdetektor 10 ist dabei zur Erkennung einer Überlast oder eines Kurzschlusses in der Einzelleitung 7 ausgebildet, indem bei Überlast bzw. Kurzschluss der Auslöse- stift 37 in die Spulenwicklung des Lastdetektors 10 hineingezogen wird. Hierdurch erzeugt der Lastdetektor 10 einen mechanischen Auslöseimpuls, der durch Verschwenkung des Betätigungsglieds 35 auf das Schaltschloss 22 übertragen wird.The load detector 10 is formed by a coil winding of the individual line 7, in which the release pin 37 is guided axially movable. The load detector 10 is designed to detect an overload or a short circuit in the individual line 7 by being pulled in overload or short circuit of the trigger pin 37 in the coil winding of the load detector 10. As a result, the load detector 10 generates a mechanical trigger pulse, which is transmitted by pivoting of the actuator 35 to the switch lock 22.
Durch diesen mechanischen Auslöseimpuls wird das Schaltschloss 22 ausgelöst und die Schalteinheit 12 zur Unterbrechung des Stromflusses in der Hauptstrombahn 6 betätigt.By this mechanical trigger pulse, the switching mechanism 22 is triggered and the switching unit 12 is actuated to interrupt the flow of current in the main flow path 6.
Zumal alle Komponenten der Hauptstrombahn 6, insbesondere die Einzelleitungen 7 mit jeweils zugeordnetem Lastdetektor 10, Wandler 11 und Einzelschalter 12 vollständig in der Schalt- kammer 2 angeordnet sind, kann das Schaltgerät 1 nach Ablauf der elektrischen Lebensdauer durch einfachen Austausch der Schaltkammer 2 wieder einsatzfähig gemacht werden. Die ver- brauchte Schaltkammer 2 ist zu diesem Zweck von dem weiterverwendbaren Basismodul 3 nach Lösen der Befestigungsschrauben 4 einfach abziehbar. Insbesondere wird dabei der Signalkreis 33 durch Dekontaktieren des Steckkontakts 34 automa- 0Especially since all components of the main current path 6, in particular the individual lines 7, each with assigned load detector 10, converter 11 and individual switch 12 are arranged completely in the switching chamber 2, the switching device 1 can be made operational again by simply replacing the switching chamber 2 after the end of the electrical life become. The used switching chamber 2 is for this purpose easily removable from the reusable base module 3 after loosening the mounting screws 4. In particular, the signal circuit 33 is automatically reset by decontacting the plug-in contact 34. 0
tisch getrennt. Ebenso entklinkt das Betätigungsglied 35 dabei automatisch von dem Auslösestift 37. Beim Aufstecken einer neuen Schaltkammer 2 werden diese Wirkverbindungen selbsttätig wiederhergestellt, so dass beide Schutzschalt- einheiten 30 und 31 nach dem Zusammenstecken der Schaltkammer 2 und des Basismoduls 3 sofort wieder einsatzfähig sind.separated table. When activating a new switching chamber 2, these active compounds are automatically restored, so that both Schutzschalt- units 30 and 31 after mating the switching chamber 2 and the base module 3 are immediately ready for use again.
Die Wiederverwendbarkeit des Schaltgeräts 1 ist optional noch weiter gesteigert, indem die Anschlussklemmen 8 und 9 jeweils in einem separaten Klemmenblock 39 bzw. 40 angeordnet sind, der auf die Schaltkammer 2 aufsteckbar ist. Zumal die An- schlussklemmen 8,9 im ordnungsgemäßen Betrieb des Schaltgeräts 1 keinem nennenswerten elektrischen Verschleiß unterliegen, können die Klemmenblöcke 39,40 bei einem Austausch der Schaltkammer 2 von derselben abgezogen und ebenfalls weiterverwendet werden. The reusability of the switching device 1 is optionally further increased by the terminals 8 and 9 are each arranged in a separate terminal block 39 and 40, which can be plugged onto the switching chamber 2. Especially since the terminals 8.9 are not subject to any significant electrical wear in the proper operation of the switching device 1, the terminal blocks 39,40 can be deducted from the same in an exchange of the switching chamber 2 and also be used.
