- wobei der Kontakt bei Beaufschlagen der elektromagnetischen Antriebsvorrichtung mit einem Anzugsstrom von der elektromagnetischen Antriebsvorrichtung mittels eines Kontaktbrückenträgers von einer Trennstellung in eine Überbrückungsstellung überführbar ist,

Derartige Schaltgeräte sind allgemein bekannt. Lediglich beispielhaft wird auf die
Zur Sicherstellung der Spannungsfreiheit von elektrischen Anlagen bei Arbeiten an bzw. in diesen Anlagen sind Hauptschalter bzw. Schaltgeräte mit Trennereigenschaften vorgeschrieben. Diese müssen zum einen entweder durch eine sichtbare Trennstrecke oder durch eine Anzeige, die den Schaltzustand des Geräts sicher anzeigt, die Abtrennung der Anlage von der Versorgung sicher signalisieren. Vor allem aber müssen sie eine Absperrung ermöglichen, die ein versehentliches Einschalten sicher verhindert. Außerdem muss eine erhöhte Spannungsfestigkeit über die Schaltstelle sicher gestellt sein. Auch dürfen vorbestimmte Kriechströme nicht überschritten werden.To ensure the absence of voltage from electrical systems when working on or in these systems, main switches or switching devices with isolating properties are required. On the one hand, these must reliably signal the disconnection of the system from the supply either by means of a visible isolating distance or by a display which reliably indicates the switching state of the device. Above all, they must allow a barrier that prevents accidental switching on safely. In addition, an increased dielectric strength must be ensured via the switching point. Also, predetermined leakage currents must not be exceeded.
Geräte dieser Art sind beispielsweise in der IEC 60947-2 und der IEC 60947-3 beschrieben. Realisiert sind diese Normen in elektrischen Geräten wie beispielsweise Trennern, Lasttrennern, Sicherungslasttrennern und Leistungsschaltern mit Trennfunktion und ähnlichen Geräten.Devices of this type are described, for example, in IEC 60947-2 and IEC 60947-3. These standards are implemented in electrical equipment such as disconnectors, load disconnectors, fuse disconnectors and circuit breakers with disconnecting function and similar devices.
Elektromagnetische Schaltgeräte gemäß dem oben genannten Stand der Technik erfüllen diese Anforderungen.Electromagnetic switching devices according to the above-mentioned prior art meet these requirements.
Die
Die Aufgabe der vorliegenden Erfindung besteht darin, ein weiteres gattungsgemäßes elektromagnetisches Schaltgerät zu schaffen.The object of the present invention is to provide a further generic electromagnetic switching device.
Die Aufgabe wird durch Merkmale des Anspruch 1 gelöst, so dass das Zusatzgerät an das Grundgerät an einer Geräteseite angrenzt, die senkrecht zu einer Verschieberichtung des Kontaktbrückenträgers verläuft.The object is solved by features of claim 1, so that the additional device is adjacent to the base unit on a side of the device, which is perpendicular to a direction of displacement of the contact bridge carrier.
Wenn der Kontakt durch Einführen des Arretierelements in eine Arretierelementaufnahme blockierbar ist, ist das Schaltgerät konstruktiv besonders einfach ausgebildet. Die Arretierelementaufnahme kann dabei alternativ beidseitig oder nur einseitig offen sein.If the contact can be blocked by inserting the locking element into a locking element receptacle, the switching device is structurally particularly simple. The locking element receptacle can alternatively be open on both sides or only on one side.
Wenn das Arretierelement unverlierbar im Zusatzgerät gehalten ist, ist zum Blockieren des Kontakts kein separates Element erforderlich. Darüber hinaus kann in diesem Fall das Arretierelement an das Zusatzgerät, insbesondere an eine etwaige Arretierelementaufnahme, angepasst sein. Toleranzen sind daher vorbekannt bzw. können minimiert werden.If the locking element is held captive in the auxiliary device, no separate element is required to block the contact. In addition, in this case, the locking element to the attachment, in particular to a possible locking element, be adapted. Tolerances are therefore previously known or can be minimized.
Wenn das Zusatzgerät einen Zusatzschalter aufweist, der in einen Stromkreis einschleifbar ist, über den die elektromagnetische Antriebsvorrichtung mit dem Anzugsstrom beaufschlagbar ist, ist eine Energieversorgung der elektromagnetischen Antriebsvorrichtung am Schaltgerät unterbrechbar,If the auxiliary device has an additional switch which can be looped into a circuit via which the electromagnetic drive device can be acted upon by the starting current, a power supply of the electromagnetic drive device to the switching device can be interrupted,
Wenn der Zusatzschalter derart angeordnet und ausgebildet ist, dass er beim mechanischen Blockieren des Kontakts geöffnet wird, kann es nicht geschehen, dass versehentlich ein Öffnen des Spulenstromkreises unterbleibt.When the auxiliary switch is arranged and configured to open when mechanically blocking the contact it can not happen that accidentally opening the coil circuit is omitted.
Die Verbindung zwischen Zusatzgerät und Grundgerät kann alternativ lösbar oder unlösbar sein. Zumindest bei in der Trennstellung mechanisch blockiertem Kontakt sollte das Zusatzgerät aber unlösbar mit dem Grundgerät verbunden sein.The connection between additional device and basic device can alternatively be solvable or insoluble. At least when mechanically blocked in the disconnected position contact the accessory should be inextricably linked to the basic unit.
Die Verbindung zwischen Grundgerät und Zusatzgerät gestaltet sich besonders einfach, wenn das Zusatzgerät mit dem Grundgerät verrastet ist.The connection between the basic device and the additional device is particularly easy if the auxiliary device is locked to the basic device.
Wenn mit dem Schaltgerät ein Hilfsschaltergehäuse verbindbar ist, in dem ein Hilfsschalter angeordnet ist, der vom Kontaktbrückenträger zusammen mit dem Kontakt betätigbar ist, ist das Schaltgerät noch flexibler einsetzbar. Der Hilfsschalter ist dabei mit dem Kontaktbrückenträger vorzugsweise spielfrei verbunden. Die Verbindung kann aber alternativ direkt oder indirekt sein.If an auxiliary switch housing is connectable to the switching device, in which an auxiliary switch is arranged, which can be actuated by the contact bridge carrier together with the contact, the switching device is even more flexible. The auxiliary switch is connected to the contact bridge carrier preferably without play. Alternatively, the connection may be direct or indirect.

Gemäß den FIG 1 und 2 ist ein Grundgerät 1 eines elektromagnetischen Schaltgeräts beispielhaft als Schütz ausgebildet. Das Schütz weist unter anderem eine elektromagnetische Antriebsvorrichtung 2, einen Anker 3, einen Kontaktbrückenträger 4 und - in der Regel mehrere - elektrische Kontakte 5 auf. Der Übersichtlichkeit halber ist dabei in den FIG 1 und 2 nur ein Kontakt 5 dargestellt. Jeder Kontakt 5 besteht in der Regel aus zwei feststehenden Kontaktstellen 5' und einer beweglichen Kontaktbrücke 5".According to Figures 1 and 2, a basic unit 1 of an electromagnetic switching device is exemplified as a contactor. The contactor has, among other things, an
Die elektromagnetische Antriebsvorrichtung 2 weist eine Spule 2' und einen Spulenkern 2" auf. Die Spule 2' ist über eine Ansteuereinheit 6 mit einem Anzugsstrom I beaufschlagbar. In diesem Fall wird der Anker 3 angezogen und dadurch der Kontaktbrückenträger 4 und mit ihm die Kontaktbrücke 5" in eine Überbrückungsstellung überführt, in welcher der Kontakt 5 geschlossen ist. Dieser Zustand ist in FIG 1 dargestellt.The
Wenn die Spule 2" hingegen nicht mit dem Anzugsstrom I beaufschlagt wird, werden der Kontaktbrückenträger 4 und mit ihm die Kontaktbrücke 5" mittels einer Rückstellfeder in eine Trennstellung überführt, in welcher der Kontakt 5 geöffnet ist. Diese Stellung ist in FIG 2 dargestellt. Die Rückstellfeder ist dabei der Übersichtlichkeit halber nicht mit dargestellt.If the
Der Kontaktbrückenträger 4 wird beim Überführen von der Trennstellung in die Überbrückungsstellung und umgekehrt in einer Verschieberichtung x verschoben. Gemäß den FIG 1 und 2 grenzt an das Grundgerät 1 ein Zusatzgerät 7 an. Das Zusatzgerät 7 grenzt dabei an einer Geräteseite an das Grundgerät 1 an, die senkrecht zur Verschieberichtung x verläuft.The
Das Zusatzgerät 7 ist ebenfalls Bestandteil des elektromagnetischen Schaltgeräts. Es ist mit dem Grundgerät 1 verbunden, z. B, verrastet. Das Zusatzgerät 7 weist eine Verlängerung 8 für den Kontaktbrückenträger 4 auf. Die Verlängerung 8 ist mit dem Kontaktbrückenträger 4 - vorzugsweise spielfrei - verbunden, so dass die Verlängerung 8 vom Kontaktbrückenträger 4 zwangsgeführt wird.The
Das Zusatzgerät 7 weist eine durchgehende, also beidseitig offene, Arretierelementaufnahme 9 auf, die Verlängerung 8 eine korrespondierende Ausnehmung 10. Wenn sich der Kontaktbrückenträger 4 - und mit ihm der Kontakt 5 - in der Trennstellung befindet, kann daher gemäß FIG 2 ein Arretierelement 11 - hier z. B. der Bügel 11 eines Vorhängeschlosses 12 - manuell durch die Arretierelementaufnahme 9 hindurch geführt werden. Durch Betätigen eines Absperrelements 13, hier des Schließelements 13 des Vorhängeschlosses 12, ist somit das Arretierelement 11 in der Trennstellung des Kontaktbrückenträgers 4 abgesperrt mit dem Zusatzgerät 7 (bzw. dem Schaltgerät) verbunden. Wenn sich das Arretierelement 11 in der Arretierelementaufnahme 9 befindet, sind somit die Verlängerung 8 und mit ihr auch der Kontaktbrückenträger 4 und der Kontakt 5 in der Trennstellung mechanisch blockiert. Diese Elemente 4, 5, 8 verharren somit auch dann in der Trennstellung, wenn die elektromechanische Antriebsvorrichtung 2 mit dem Anzugsstrom I beaufschlagt wird. Das Einführen des Arretierelements 11 in die Arretierelementaufnahme 9 kann dabei ersichtlich bei vollständig montiertem Schaltgerät erfolgen.The
Es ist möglich, dass die Verbindung des Zusatzgeräts 7 mit dem Grundgerät 1 lösbar ist. Vorzugsweise aber ist sie unlösbar, zumindest dann, wenn der Kontakt 5 in der Trennstellung mechanisch blockiert ist. Meist ist es sogar von Vorteil, wenn das Zusatzgerät 7 mit dem Grundgerät 1 dauerhaft unlösbar verbunden ist.It is possible that the connection of the
Gemäß den FIG 1 und 2 weist das Schaltgerät einen Zusatzschalter 14 auf, der im Zusatzgerät 7 angeordnet ist. Der Zusatzschalter 14 ist gemäß den FIG 1 und 2 in einen Stromkreis eingeschleift, über den die elektromagnetische Antriebsvorrichtung 2 mit dem Anzugsstrom I beaufschlagbar ist. Er ist ferner ersichtlich derart angeordnet und ausgebildet, dass er den Stromkreis beim Einführen des Arretierelements 11 in die Arretierelementaufnahme 9, also beim mechanischen Blockieren des Kontakts 5, unterbricht. Ein versehentliches Einschalten der elektromagnetischen Antriebsvorrichtung 2 bei blockiertem Kontaktbrückenträger 4 ist somit nicht möglich. Etwaige mögliche Schäden durch eine zu lange andauernde hohe Strombelastung der Spule 2' werden somit vermieden.According to FIGS. 1 and 2, the switching device has an
Die Ausführungsformen gemäß den FIG 3 und 4 entsprechen im Wesentlichen der Ausführungsform gemäß den FIG 1 und 2. Gemäß FIG 3 ist auf das Zusatzgerät 7 an einer dem Grundgerät 1 gegenüberliegenden Seite aber ein Hilfsschaltergehäuse 15 aufgesetzt und mit dem Zusatzgerät 7 verbunden. Das Hilfsschaltergehäuse 15 kann mit dem Zusatzgerät 7 beispielsweise verrastet sein. Im Hilfsschaltergehäuse 15 ist ein Hilfsschalter 16 angeordnet. Der Hilfsschalter 16 wird vom Kontaktbrückenträger 4 zusammen mit dem Kontakt 5 betätigt.The embodiments according to FIGS. 3 and 4 essentially correspond to the embodiment according to FIGS. 1 and 2. According to FIG. 3, an
Wegen der Aufteilung des Schaltgeräts in das Grundgerät 1 und das Zusatzgerät 7 ist der Hilfsschalter 16 vom Kontaktbrückenträger 4 nur über die verlängerung 8 und damit indirekt betätigbar. Bei entsprechender einteiliger Ausgestaltung des Schaltgeräts wäre aber auch eine direkte Betätigung möglich. In jedem Fall sollte der Hilfsschalter 16 aber vom Kontaktbrückenträger 4 spielfrei betätigbar sein.Because of the distribution of the switching device in the base unit 1 and the
Bei der Ausgestaltung gemäß FIG 4 ist - im Unterschied zu den FIG 1 und 3 - die Arretierelementaufnahme 9 nur einseitig offen. Ferner ist das Arretierelement 11 bei der Ausführungsform gemäß FIG 4 mit dem Zusatzgerät 7 permanent verbunden. Hierzu weisen das Arretierelement 11 und die Arretierelementaufnahme 9 zusammenwirkende Halte- und Rastelemente 17, 18 auf, mittels derer das Arretierelement 11 unverlierbar im Zusatzgerät 7 gehalten ist. Gemäß FIG 4 entspricht das eine der Halte- und Rastelemente 17, 18 einem Betätigungsorgan für den Zusatzschalter 14. Das Betätigungsorgan für den Zusatzschalter 14 könnte aber auch ein separates Element sein.In the embodiment according to FIG. 4, in contrast to FIGS. 1 and 3, the locking
Mittels der erfindungsgemäßen Ausgestaltung des elektromagnetischen Schaltgeräts kann somit das elektromagnetische Schaltgerät auf einfache Weise um Trennereigenschaften erweitert werden.By means of the embodiment of the electromagnetic switching device according to the invention, the electromagnetic switching device can thus be easily extended by separator properties.
