Schutzschaltgerät mit Fernauslösung 5Circuit breaker with remote release 5
Die Erfindung betrifft ein Schutzschaltgerät mit einem Prüfstromkreis, der in EIN-Stellung durch eine Prüftaste betätigbar ist, deren Anschlußpunkte in EIN-Stellung mit Anschlußklemmen zur Fernauslösung elektrisch leitend verbunden sind.The invention relates to a protective switching device with a test circuit, which can be actuated in the ON position by a test button, the connection points of which in the ON position are electrically connected to connection terminals for remote triggering.
Von derartigen bekannten Schutzschaltgeräten - z.B. Fehlerstromschutzschaltern (Fl) Differenzstromschutzschaltern DI) oder kombinierten Geräten, z.B. Fehlerstrom-/Leitungsschutzschaltern (FI/LS) - fordern die Anwender im Zuge einer fortschrittlichen Elektroinstallation immer mehr Zusatzfunktionen, wie z.B. Hilfsschalter und/oder Fernauslösung. Die Zusatzfunktion "Fernauslösung" arbeitet bei diesen Geräten auf die Prüfeinrichtung des Schalters, wobei für die Fernauslösung parallel die Anschlußpunkte A, 5 der Prüftaste 3 an zwei Anschlußklemmen 6, 7 geführt sind, wie in FIG 2 dargestellt. Diese Ausführung hat jedoch den schwerwiegenden Nachteil, daß die Anschlußklemmen 6, 7 für die Fernauslösung nur in Verbindung mit dem vorgesehenen Anschluß des Netzes und der Last an die Netzklemme 1-N bzw. an die Lastklemme 2-N am Schutzschaltgerät spannungsfrei geschaltet werden können.In the course of advanced electrical installations, users are increasingly demanding more additional functions from such known protective switching devices - e.g. residual current circuit breakers (Fl) differential current circuit breakers DI) or combined devices, e.g. residual current/circuit breakers (FI/LS) - such as auxiliary switches and/or remote tripping. The additional function "remote tripping" in these devices works on the test device of the switch, whereby the connection points A, 5 of the test button 3 are connected in parallel to two connection terminals 6, 7 for remote tripping, as shown in FIG 2. However, this design has the serious disadvantage that the connection terminals 6, 7 for remote tripping can only be switched off in conjunction with the intended connection of the network and the load to the network terminal 1-N or to the load terminal 2-N on the protective switching device.
Zur Sicherheit ist daher die Kennzeichnung von "Netz" bzw. "Lastseite" am Schaltgerät erforderlich oder es wird im Bereich der Anschlußklemmen für die Fernauslösung am Schaltgerät ein Hinweis angebracht, der diesen Mangel aufzeigt. Die Gefährdung von Personen, die das Schutzschaltgerät handhaben und bedienen, ist auf diese Weise zumindest etwas vermindert.For safety reasons, it is therefore necessary to mark the "mains" or "load side" on the switching device or to attach a note to the switching device in the area of the connection terminals for remote release to indicate this defect. The risk to people handling and operating the protective switching device is at least somewhat reduced in this way.
92 G 3 5 3 3 DE92 G 3 5 3 3 EN
Ein weiteres, hiervon getrenntes Problem ist dadurch gegeben, daß bei Schaltgeräten in kleiner Bauweise z.B. die Zusatzfunktion Fernauslösung nicht mehr im Gerät untergebracht werden kann.A further, separate problem is that in switching devices with a small design, the additional function of remote triggering, for example, can no longer be accommodated in the device.
In den meisten Fällen wird bei bisher auf dem Markt befindlichen FI-, DI- bzw. kombinierten Geräten im Bereich der Anschlußklemmen für die Fernauslösung ein Hinweis angebracht.In most cases, a notice is placed in the area of the connection terminals for remote release on FI, DI or combined devices currently on the market.
Der Erfindung liegt die Aufgabe zugrunde, ein Schutzschaltgerät der obengenannten Art zu schaffen, bei dem die für die Fernauslösung vorgesehenen Anschlußklemmen in AUS-Stellung des Gerätes spannungsfrei sind. Dies läßt sich erreichen mit den Merkmalen nach Anspruch 1. Bei dieser Lösung sind die Anschlußklemmen für die Auslösung unabhängig von der Anschlußrichtung des Schutzschaltgerätes in AUS-Stellung spannungsfrei geschaltet und es kann jeglicher zusätzlicher Hinweis entfallen. Eine besonders einfache Ausführungsform der Erfindung besteht, wenn die Schaltstellung des Hilfskontakts von der Mechanik des Schutzschaltgeräts für die Schaltkontakte steuerbar ist.The invention is based on the object of creating a protective switching device of the above-mentioned type in which the connection terminals provided for remote triggering are de-energized when the device is in the OFF position. This can be achieved with the features according to claim 1. In this solution, the connection terminals for triggering are de-energized in the OFF position regardless of the connection direction of the protective switching device and any additional information can be omitted. A particularly simple embodiment of the invention exists when the switching position of the auxiliary contact can be controlled by the mechanics of the protective switching device for the switching contacts.
Vorteilhafterweise wird bei Schaltgeräten, bei denen die Anschlußklemmen für die Fernauslösung wegen kleiner Bauweise im Schaltgerät selbst nicht untergebracht werden können, sowohl der Hilfskontakt und die Anschlußklemmen für die Fernauslösung in einem meist schon vorhandenen Schaltergehäuse untergebracht (z.B. im Hilfsschaltergehäuse).Advantageously, in the case of switching devices in which the connection terminals for remote release cannot be accommodated in the switching device itself due to their small size, both the auxiliary contact and the connection terminals for remote release are accommodated in a switch housing that is usually already present (e.g. in the auxiliary switch housing).
Nachdem zur Spannungsfreischaltung der Anschlußklemmen für die Fernauslösung meist nur ein einziger Hilfskontakt benötigt wird und in einem Hilfsschaltergehäuse im Regelfall zwei Kontaktebenen vorhanden sind, wird zweckmäßigerweiseSince only a single auxiliary contact is usually required to de-energize the connection terminals for remote release and there are usually two contact levels in an auxiliary switch housing, it is advisable
92 G 3 5 3 3 DE92 G 3 5 3 3 EN
die zweite Kontaktebene mit einem zweiten Hilfskontakt für die Schaltstellungsmeldung verwendet.the second contact level with a second auxiliary contact is used for the switch position signal.
Im folgenden wird eine Ausführungsform der Erfindung im einzelnen anhand einer Zeichnung erläutert.In the following, an embodiment of the invention is explained in detail with reference to a drawing.
Die FIG 1 zeigt ein Schutzschaltgerät mit einem Prüfstromkreis P, einer Netzklemme 1, einer Lastklemme 2, zwei Nullleiterklemmen N und mechanisch gekoppelten SchaltkontaktenFIG 1 shows a protective switching device with a test circuit P, a mains terminal 1, a load terminal 2, two neutral conductor terminals N and mechanically coupled switching contacts
8. Die elektrische Verbindung zwischen der Netzklemme 1 und der Lastklemme 2 einerseits sowie zwischen den beiden Nullleiterklemmen N andererseits wird durch die darin liegenden Schaltkontakte 8 im Fehlerfall aufgetrennt. Der dritte, im Prüfstromkreis P liegende Schaltkontakt ist mit den anderen beiden genannten Schaltkontakten 8 mechanisch gekoppelt und weist somit dieselbe Schaltstellung auf. Zu Prüfzwecken kann über eine Prüftaste 3 im Prüfstromkreis P ein Differenzstrom simuliert werden, durch den bei einwandfreier Funktion des Schutzschaltgerätes die Schaltkontakte 8 sämtlich in AUS-Stellung wechseln.8. The electrical connection between the mains terminal 1 and the load terminal 2 on the one hand and between the two neutral conductor terminals N on the other hand is broken by the switching contacts 8 located therein in the event of a fault. The third switching contact located in the test circuit P is mechanically coupled to the other two switching contacts 8 mentioned and therefore has the same switching position. For testing purposes, a test button 3 in the test circuit P can be used to simulate a differential current, which causes all switching contacts 8 to switch to the OFF position if the protective switching device is functioning properly.
In einem getrennten Hilfsschaltergehäuse 10 sind zwei Hilfskontakte 9, 11 untergebracht, die durch die Mechanik für die Schaltkontakte 8 gesteuert sind und somit dieselbe Schaltstellung einnehmen. Davon ist der Schaltkontakt 8 an den netzseitigen Anschlußpunkt 4 der Prüftaste 3 angeschlossen und andererseits an eine Anschlußklemme 7 zur Fernauslösung des Schutzschaltgeräts geführt. Die andere Anschlußklemme 6 zur Fernauslösung geht von dem weiteren Anschlußpunkt 5 der Prüftaste 3 ab.Two auxiliary contacts 9, 11 are housed in a separate auxiliary switch housing 10, which are controlled by the mechanism for the switching contacts 8 and thus assume the same switching position. The switching contact 8 is connected to the mains-side connection point 4 of the test button 3 and on the other hand to a connection terminal 7 for remote triggering of the protective switching device. The other connection terminal 6 for remote triggering goes off from the other connection point 5 of the test button 3.
Somit ist sichergestellt,, daß zwar in der EIN-Stellung des Schutzschaltgerätes an der Anschlußklemme 7 Netzspannungspotential ansteht und die Fernauslösung durchgeführt werdenThis ensures that, although the circuit breaker is in the ON position, mains voltage potential is present at terminal 7 and remote tripping can be carried out
G 3 5 3 3 DEG 3 5 3 3 EN
kann, daß aber bei AUS-Stellung des Schutzschaltgeräts die Anschlußklemme 7 durch den Hilfsschalter 9 spannungsfrei geschaltet ist.can, but that when the protective switching device is in the OFF position, the connecting terminal 7 is de-energized by the auxiliary switch 9.
Der weitere im Hilfsschaltergehäuse 10 vorhandene Hilfskontakt 11 wird vorteilhafterweise zur Schaltstellungsmeldung des Schaltgerätes verwendet.The additional auxiliary contact 11 in the auxiliary switch housing 10 is advantageously used to signal the switching position of the switching device.
Sofern im Gehäuse des Schutzschaltgeräts genügend Raum vorhanden ist, kann selbstverständlich auf ein zusätzliches Hilfsschaltergehäuse verzichtet werden und der Hilfskontakt 9 sowie die beiden Anschlußklemmen 6 und 7 für die Fernauslösung in diesem Gehäuse vorgesehen werden.If there is sufficient space in the housing of the protective switching device, an additional auxiliary switch housing can of course be dispensed with and the auxiliary contact 9 and the two connection terminals 6 and 7 for remote tripping can be provided in this housing.
Ein derartiges Schutzschaltgerät mit Fernauslösung und Schaltzustandsmeldung ist für einen Einsatz bei der Gebäudesystemtechnik gut geeignet.Such a protective switching device with remote triggering and switching status reporting is well suited for use in building system technology.
