Abstract

It is constructed from three-terminal modules (13) which form highly varied devices which electrically have one or more terminals, if required with the addition of a neutral conductor path. A three-terminal module (13) has a main current path (1) having at least one contact point (2). Said contact point can be switched by means of a tripping device (3) or a remote-control device, if required also by means of a manual operating device and, if required, also via a latching mechanism (6). A branch (7) having a current-limiting device (8) is passed out of the module to an external connection, which may be internally connected in a switching device (10). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Schalteinrichtung zur Unterbrechung eines Stromkreises, die mit einem dreipoligen Modul arbeitet, das einen Hauptstrompfad mit zumindest einer Kontakteinrichtung aufweist, von dem ein Abzweig mit einer Strombegrenzungseinrichtung zu einem eigenen externen Anschluß herausgeführt ist. Ein derartiges Modul ist Gegenstand einer Anmeldung mit älterem Zeitrang (EP: 90 113 093.0). Dem Hauptstrompfad nachgeordnete Bauelemente oder Einrichtungen werden schon während des Abschaltvorgangs gegen zu hohe Stromquadrat-Zeit-Werte geschützt. Dieser Schutz gegen Überstrom kommt insbesondere im Kurzschlußfall zum Tragen. Die Überleitung zu hoher Ströme auf den Abzweig entlastet die dem Hauptstrompfad nachgeordneten Einrichtungen.The invention relates to a switching device for interrupting a circuit, which works with a three-pole module, which has a main current path with at least one contact device, from which a branch is led out with a current limiting device to its own external connection. Such a module is the subject of an application with an older seniority (EP: 90 113 093.0). Components or devices arranged downstream of the main current path are already protected against excessive current square time values during the switch-off process. This protection against overcurrent is particularly important in the event of a short circuit. The transfer of excessively high currents to the branch relieves the facilities downstream of the main current path.

Die Wirkung des Abzweigs im geschilderten dreipoligen Modul geht über die Wirkung von bekannten Limitern hinaus. So beruhen Limiter zwar auf dem Prinzip den Strom über eine Schaltstrecke im Abschaltfall zusätzlich dadurch zu begrenzen, daß weitere strombegrenzende Mittel eingeschaltet werden, es werden aber hinsichtlich dem Hauptstrompfad nachgeordneter Einrichtungen keine Ströme abgeleitet. Eine derartige Ableitung und nicht nur eine Strombegrenzung ermöglicht weitere Wirkungsweisen, beispielsweise die Entkopplung eines Eingangsstromkreises vom Ausgangsstromkreis, was bei einer größeren Induktivität im Ausgang besonders zum Tragen kommen kann. Limiter, die dagegen nur eine Strombegrenzung im Hauptstrompfad bewirken sollen, sind in den verschiedenartigsten Ausführungen bekannt (beispielsweise EP-A-0 350 825).The effect of the branch in the three-pole module described goes beyond the effect of known limiters. Thus, limiters are based on the principle of additionally limiting the current over a switching path in the event of a shutdown by switching on further current-limiting means, but no currents are derived with respect to the main current path of downstream devices. Such a derivation and not only a current limitation enables further modes of operation, for example the decoupling of an input circuit from the output circuit, which can be particularly important in the case of a larger inductance in the output. Limiters, on the other hand, which are only intended to limit the current in the main current path, are known in a wide variety of designs (for example EP-A-0 350 825).

Der Erfindung liegt die Aufgabe zugrunde, aus einem dreipoligen Modul der geschilderten Art unter Nutzung der besonderen Vorteile die verschiedenartigsten Schalteinrichtungen aufzubauen:The invention has for its object to build a variety of switching devices from a three-pole module of the type described using the special advantages:

Die Lösung der geschilderten Aufgabe erfolgt durch eine Schalteinrichtung nach Patentanspruch 1. Aus dem dreipoligen Modul werden danach die verschiedenartigsten elektrisch einpoligen oder mehrpoligen Einrichtungen gebildet, gegebenenfalls unter Hinzufügung eines Neutralleiterpfades. Wenn hier von einem dreipoligen Modul gesprochen wird, so ist dabei ein Gebilde mit drei Anschlüssen gemeint, entsprechend der Vierpol-Theorie der Nachrichtentechnik. Hiervon zu unterscheiden sind elektrische Pole womit Außenleiter, früher Phasenleiter genannt, bezeichnet werden. Elektrische Pole können, wie in Verbrauchernetzen üblich, in Verbindung mit Neutralleitern durch Schalteinrichtungen hinsichtlich nachgeordneter Einrichtungen unterbrochen werden.The described task is solved by a switching device according to claim 1. The most diverse electrical single-pole or multi-pole devices are then formed from the three-pole module, optionally with the addition of a neutral conductor path. When we speak of a three-pole module, we mean a structure with three connections, according to the four-pole theory of telecommunications. Electrical poles are to be distinguished from this, which are used to denote outer conductors, formerly called phase conductors. As is common in consumer networks, electrical poles can be interrupted in connection with neutral conductors by switching devices with regard to downstream devices.

Ein dreipoliges Modul weist einen Hauptstrompfad mit mindestens einer Kontaktstelle auf. Diese kann mittels eines oder mehrerer Auslöseorgane und bzw. oder durch Fernwirkeinrichtungen und bzw. oder durch ein Handbetätigungsorgan geschaltet werden. Gegebenenfalls kann zwischen Auslöseorganen und Kontaktstelle ein Schaltschloß zwischengeschaltet werden. Der Abzweig vom Hauptstrompfad weist eine Strombegrenzungseinrichtung auf und führt im Modul zu einem eigenen externen Anschluß.A three-pole module has a main current path with at least one contact point. This can be switched by means of one or more trigger elements and / or by remote control devices and / or by a manual control element. If necessary, a switch lock can be interposed between the release elements and the contact point. The branch from the main current path has a current limiting device and leads to its own external connection in the module.

Über den Abzweig können Ströme abgeleitet werden, die wiederum durch die Strombegrenzungseinrichtung begrenzt werden können.Currents can be derived via the branch, which in turn can be limited by the current limiting device.

Es sind Anwendungsfälle ersichtlich, bei denen es vorteilhaft ist, die Auslöseorgane bzw. Erfassungselemente und bzw. oder Schaltschlösser bzw. Auslöseelemente der einzelnen elektrischen Pole untereinander oder auch zwischen Dreipolen zusammenarbeiten zu lassen.Applications can be seen in which it is advantageous to have the tripping elements or detection elements and / or switch locks or tripping elements of the individual electrical poles cooperate with one another or also between tripoles.

Der Abzweig bzw. die Abzweige bei mehreren Dreipolen, können zu elektrisch gleichpoligen Anschlüssen herausgeführt werden. So können die Abzweige insbesondere mit einem Neutralleiter verbunden werden.The branch or the branches in the case of several three-pole connections can be led out to electrically equipolar connections. In this way, the branches can be connected in particular to a neutral conductor.

Man erhält einen elektrischen Zweipol, wenn man zwei Dreipole mit ihren Abzweigen verbindet und mit ihren anderen beiden Polen jeweils zwei elektrische Anschlüsse auf jeder Anschlußseite bilden läßt.You get an electrical two-pole if you connect two three-pole with their branches and with their other two poles each have two electrical connections on each connection side.

Mehrere Dreipole können jeweils mit ihrem Abzweig zu einem gemeinsamen Anschlußzweig für einen Neutralleiter zusammengeführt werden und die Hauptstrompfade der einzelnen Dreipole können Anschlüsse für einzelne Außenleiter, beispielsweise eines Dreiphasennetzes bilden.Several triple poles can each be merged with their branch to form a common connection branch for a neutral conductor, and the main current paths of the individual triple poles can form connections for individual external conductors, for example a three-phase network.

Der oben geschilderte Zweipol eignet sich bei entsprechenden Kontaktstellen auch zur Unterbrechung eines zweipoligen Gleichstromnetzes, wobei jeder Hauptstrompfad in einen elektrischen Polleiter eingeschaltet ist.The two-pole connector described above is also suitable for interrupting a two-pole direct current network with corresponding contact points, each main current path being connected to an electrical pole conductor.

Die Erfindung soll nun anhand von in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispielen näher erläutert werden:

In FIG 1
ist ein Beispiel für einen Dreipol veranschaulicht.
In FIG 2
ist ein Ausführungsbeispiel für einen elektrischen Zweipol, aufgebaut aus drei Polen nach Figur 1, wiedergegeben.

ist ein weiteres Ausführungsbeispiel für einen symmetrischen elektrischen Zweipol bzw. für einen Außenleiter und für einen Neutralleiter veranschaulicht.
In FIG 8
ist ein weiteres Ausführungsbeispiel für einen vollsymmetrischen elektrischen Zweipol, also beispielsweise für zwei Außenleiter, veranschaulicht.
The invention will now be explained in greater detail on the basis of exemplary embodiments shown roughly schematically in the drawing:
In FIG. 1
is an example of a three pole illustrated.
In FIG. 2
is an embodiment of an electrical two-pole, made up of three poles according to Figure 1, shown.

is a further embodiment of a fully symmetrical electrical two-pole, so for example for two outer conductors illustrated.

Das dreipolige Modul nach Figur 1 weist einen Hauptstrompfad 1 auf, in dem zumindest eine Kontaktstelle 2 angeordnet ist. Im Ausführungsbeispiel kann diese mittels Auslöseorgan 3 unter Zwischenschaltung eines Schaltschlosses 4 geöffnet und geschlossen werden. Im Ausführungsbeispiel weist das Schaltschloß 4 ein Handbetätigungsorgan 5 auf. Die Komponente mit dem Auslöseorgan 3 kann auch als Fernwirkeinrichtung ausgeführt sein, die an einem äußeren Anschluß 6 extern angeschlossen werden kann. In einem Abzweig 7, der im Ausführungsbeispiel hinter dem Auslöseorgan 3 vom Hauptstrompfad 1 abzweigt, ist eine Strombegrenzungseinrichtung 8 eingeschaltet. Diese kann ein linearer Widerstand, auch ein komplexer Widerstand - Impedanz -, ein nichtlinearer Widerstand, eine Lichtbogenlöscheinrichtung oder allgemein eine Einrichtung zum Aufbau einer Gegenspannung bzw. einer gegenelektromotorischen Kraft, EMK, sein.The three-pole module according to FIG. 1 has a main current path 1, in which at least one contact point 2 is arranged. In the exemplary embodiment, this can be opened and closed by means of a trigger element 3 with the interposition of a switch lock 4. In the exemplary embodiment, the switching lock 4 has a manual actuating element 5. The component with the trigger element 3 can also be designed as a remote control device which can be connected externally to an external connection 6. A current limiting device 8 is switched on in a branch 7, which branches off from the main current path 1 in the exemplary embodiment behind the triggering element 3. This can be a linear resistor, also a complex resistor - impedance -, a non-linear resistor, an arc quenching device or generally a device for building a counter voltage or a counter electromotive force, EMF.

Der Abzweig 7 ist zu einem eigenen externen Anschluß 9 des dreipoligen Moduls 13 herausgeführt. Der Hauptstrompfad 1 weist Anschlüsse 11 und 12 auf. Insbesondere kann der Anschluß 12 als Eingang des Moduls 13 und der Anschluß 11 als Ausgang beschaltet werden. Es ist vorteilhaft, wenn der Anschluß 11 zusammen mit dem Anschluß 9 für den Abzweig 7 auf der Seite in einem zu unterbrechenden Netz verwandt wird, auf der die größere Induktivität besteht.The branch 7 is led out to its own external connection 9 of the three-pole module 13. The main current path 1 has connections 11 and 12. In particular, connection 12 can be connected as the input of module 13 and connection 11 as output. It is advantageous if the connection 11 together with the connection 9 for the branch 7 on the side in one interrupting network is used, on which the greater inductance exists.

Bei der Zusammenschaltung zweier Module 13 nach Figur 2 entsteht eine Schalteinrichtung 10 für zwei elektrische Pole. Die Module können einen Aufbau haben, wie er in Figur 1 dargestellt ist. Es kann auch ein in beschriebener Weise entsprechender anderer Aufbau zugrundegelegt werden. Der Anschluß 11 des ersten Moduls und der entsprechende Anschluß des zweiten Moduls, der mit 111 bezeichnet ist, dienen als entsprechende Anschlüsse der Schalteinrichtung 10. Entsprechend sind die Anschlüsse 12 und der als Anschluß 112 bezeichnete entsprechende Anschluß des zweiten Moduls zugleich die entsprechenden Anschlüsse der Schalteinrichtung 10, beispielsweise die Eingangsanschlüsse, wobei dann die Anschlüsse 11 und 111 als Ausgangsanschlüsse dienen. Der Anschluß 9 des Abzweigs des ersten Moduls 13 und der Anschluß des Abzweigs des zweiten Moduls, der mit 109 bezeichnet ist, sind miteinander elektrisch verbunden.When two modules 13 according to FIG. 2 are interconnected, a switching device 10 is created for two electrical poles. The modules can have a structure as shown in FIG. 1. A different structure corresponding to that described can also be used as a basis. The connection 11 of the first module and the corresponding connection of the second module, designated 111, serve as corresponding connections of the switching device 10. Accordingly, the connections 12 and the corresponding connection designated as connection 112 of the second module are at the same time the corresponding connections of the switching device 10, for example the input connections, the connections 11 and 111 then serving as output connections. The connection 9 of the branch of the first module 13 and the connection of the branch of the second module, which is designated by 109, are electrically connected to one another.

Die Schalteinrichtung 10 nach Figur 3 entspricht in der Beschaltung im wesentlichen dem Ausführungsbeispiel nach Figur 2, wobei zwischen den Anschlüssen der Abzweige der Module, den Anschlüssen 9 und 109 ein zusätzliches Strombegrenzungselement 14 eingeschaltet ist. Dieses kann ein linearer Widerstand, auch ein komplexer Widerstand - Impedanz -, ein nichtlinearer Widerstand, eine Lichtbogenlöscheinrichtung oder allgemein eine Einrichtung zum Aufbau einer Gegenspannung bzw. einer gegenelektromotorischen Kraft, EMK, sein. Es kann auch ein anderes unter der gegebenen Aufgabenstellung die Strombegrenzungseinrichtung 8 der dreipoligen Module 13 unterstützendes Element sein. An den Anschlüssen 12 und 112 kann beispielsweise ein Speisenetz angeschlossen werden und an den Anschlüssen 11 und 111 ein abgangsseitiges Netz für zwei elektrische Pole, beispielsweise zwei Außenleiter.The switching device 10 according to FIG. 3 corresponds essentially to the exemplary embodiment according to FIG. 2, with an additional current limiting element 14 being connected between the connections of the branches of the modules, the connections 9 and 109. This can be a linear resistor, also a complex resistor - impedance -, a non-linear resistor, an arc quenching device or generally a device for building a counter voltage or a counter electromotive force, EMF. It can also be another element supporting the current limiting device 8 of the three-pole modules 13 under the given task. For example, a feed network can be connected to the connections 12 and 112 and a network on the output side for two electrical poles, for example two outer conductors, can be connected to the connections 11 and 111.

Die Schalteinrichtung 10 nach Figur 4 ist wiederum aus zwei dreipoligen Modulen 13 aufgebaut, wobei das zweite Modul, das in der Zeichnung unten angeordnete, spiegelbildlich zum oberen Modul angeordnet ist. Die innere und äußere Beschaltung ist aus der Anschlußbezeichnung im Vergleich zu dem Ausführungsbeispiel nach den Figuren 2 und 3, bzw. nach Figur 1 zu ersehen. Eine derartige elektrisch zweipolige Schalteinrichtung ist hinsichtlich ihrer Anschlußseiten 11, 112 und 12, 111 in ihrem Verhalten symmetrisch. Ein zusätzliches Strombegrenzungselement 14 kann wahlweise eingeschaltet sein, wie es durch die gestrichelte Linie veranschaulicht ist.The switching device 10 according to FIG. 4 is in turn made up of two three-pole modules 13, the second module, which is arranged at the bottom in the drawing, being arranged in mirror image to the upper module. The internal and external wiring can be seen from the connection designation in comparison to the exemplary embodiment according to FIGS. 2 and 3 or according to FIG. 1. Such an electrical two-pole switching device is symmetrical in terms of its connection sides 11, 112 and 12, 111 in its behavior. An additional current limiting element 14 can optionally be switched on, as illustrated by the dashed line.

In Figur 5 ist ein anderes Ausführungsbeispiel für eine elektrisch zweipolige Schalteinrichtung dargestellt, im engeren Sinn für einen am Modul 13 an den Anschlüssen 12 und 11 anzuschließenden elektrischen Pol und für einen Neutralleiter dargestellt, der an den unteren Anschlüssen 15 anzuschließen ist. Im Ausführungsbeispiel ist im Neutralleiterpfad eine weitere Kontaktstelle 16 ausgebildet. Diese weitere Kontaktstelle 16 kann auch entfallen, sie ist von Vorteil, wenn die jeweiligen Landesvorschriften eine Neutralleitertrennung vorschreiben.FIG. 5 shows another exemplary embodiment for an electrically two-pole switching device, in the narrower sense for an electrical pole to be connected to the module 13 at the connections 12 and 11 and for a neutral conductor which is to be connected to the lower connections 15. In the exemplary embodiment, a further contact point 16 is formed in the neutral conductor path. This further contact point 16 can also be omitted; it is advantageous if the respective national regulations prescribe a neutral conductor separation.

In Figur 6 ist eine andere Ausführung einer Schalteinrichtung 10 wiedergegeben, wonach drei Module 13 und ein Neutralleiterpfad mit den Anschlüssen 15 eine dreipolige elektrische Schalteinrichtung mit zusätzlichem Neutralleiter bilden. Die den Anschlüssen 109, 111 und 112 des mittleren Moduls 13 entsprechenden Anschlüsse beim unteren Modul 13 sind mit 209, 211 und 212 bezeichnet. Strombegrenzungselemente 14 können im Bedarfsfall, wie veranschaulicht, eingeschaltet werden. Eine weitere Kontaktstelle 16 kann wahlweise vorgesehen werden.FIG. 6 shows another embodiment of a switching device 10, according to which three modules 13 and a neutral conductor path with the connections 15 form a three-pole electrical switching device with an additional neutral conductor. The connections corresponding to the connections 109, 111 and 112 of the middle module 13 in the lower module 13 are designated 209, 211 and 212. Current limiting elements 14 can be switched on as illustrated, if necessary. Another contact point 16 can optionally be provided.

Die Schalteinrichtung 10 nach Figur 7 ist in der ersichtlichen Weise hinsichtlich ihrer äußeren Anschlüsse symmetrisch ausgebildet, anders jedoch als im Ausführungsbeispiel nach Figur 4.The switching device 10 according to FIG. 7 is of a symmetrical design with regard to its external connections, but differently than in the exemplary embodiment according to FIG. 4.

Die Schalteinrichtung 10 nach Figur 7 veranschaulicht im weiteren Sinn eine elektrisch zweipolige Schalteinrichtung, im engeren Sinn eine einpolige elektrische Schalteinrichtung mit den Anschlüssen 12 und 112 und den Anschlüssen 15 für einen Neutralleiter.The switching device 10 according to FIG. 7 illustrates in a broader sense an electrically two-pole switching device, in the narrower sense a single-pole electrical switching device with the connections 12 and 112 and the connections 15 for a neutral conductor.

Zu einem Aufbau nach Art der Schalteinrichtung nach Figur 7 ist in Figur 8 eine Schalteinrichtung 10 für zwei elektrische Pole im engeren Sinn dargestellt. Auf den beiden Anschlußseiten sind jeweils die Anschlüsse 12 und 212 bzw. 112 und 312 verfügbar.For a construction in the manner of the switching device according to FIG. 7, a switching device 10 for two electrical poles in the narrower sense is shown in FIG.
