The electrical link to the connection point comprises at lease the section of the electrical connection to the test button.

Description

BeschreibungDescription

Fehlerstromschutz-Schalter zur Aufnahme von AnschlüssenResidual current circuit breaker for connection

Jeder Fehlerstrom-Schutzschalter üblicher Bauart weist eine Prüftaste auf, mit der sich die Einsatzbereitschaft kontrollieren lässt. Beim drücken der Prüftaste muss der Fehlerstrom-Schutzschalter auslösen, da ein Fehlerstrom erzeugt wird. Die Fehlerstromerzeugung, mittels Prüftaste, ist in dem Fehlerstrom-Schutzschalter integriert und Bestandteil eines in sich geschlossenen Systems.Every residual current circuit breaker of a standard design has a test button that can be used to check whether it is ready for use. When the test button is pressed, the residual current circuit breaker must trip because a residual current is generated. The generation of the residual current, using the test button, is integrated into the residual current circuit breaker and is part of a self-contained system.

In regelmässigen Abständen bzw. bei Inbetriebnahme einer E.-Anlage empfiehlt es sich, die Funktionsfahigkeit zu überprüfen. Die in den Bestimmungen bzw. Vorschriften enthaltenen Prüflristen sind daher zu beachten.It is advisable to check the functionality of an electrical system at regular intervals or when it is put into operation. The test schedules contained in the regulations and rules must therefore be observed.

Wird der Fehlerstrom-Schutzschalter durch die Prüftaste ausgelöst, ist die Prüfung abgeschlossen und diese Baugruppe für Einsatzbereit und Funktionsfähig erklärt.If the residual current circuit breaker is triggered by the test button, the test is completed and this assembly is declared ready for use and functional.

Somit wird die Fehlerstromerzeugung mittels Prüftaste, nur für diesen Zweck genutzt.Thus, the fault current generation via test button is used only for this purpose.

Die zunehmende Bedeutung, Gefahren so früh wie möglich zu erkennen und bei Gefahr einen schnellen Abschaltvorgang einzuleiten, um Schäden so gering wie möglich zu halten, erfordert insbesondere von der Fehlerstromerzeugung mittels Prüftaste des Fehlerstrom-Schutzschalters, externe Anwendungsmöglichkeiten der Benutzung.The increasing importance of detecting dangers as early as possible and initiating a rapid shutdown process in the event of danger in order to keep damage as low as possible requires external application options, particularly for the generation of residual current by means of the test button of the residual current circuit breaker.

Zur Abhilfe lässt sich nicht ohne weiteres ein üblicher Fehlerstrom-Schutzschalter verwenden, denn die Fehlerstromerzeugung mittels Prüftaste ist nicht zugänglich für andereAnwendungen.A conventional residual current circuit breaker cannot simply be used to remedy this, because the residual current generation using the test button is not accessible for other applications.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, einen Fehlerstrom-Schutzschalter zu schaffen, dessen Fehlerstromerzeugung mittels Prüftaste, für externe Anwendungsmöglichkeiten der Benutzung zugänglich gemacht wird, in dem parallel zur Prüftaste Anschlussmöglichkeiten geschaffen werden.The invention specified in claim 1 is based on the problem of creating a residual current circuit breaker whose residual current generation is made accessible for external application possibilities by means of a test button, in which connection possibilities are created parallel to the test button.

Dieses Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.

Mit der Erfindung wird erreicht, dass mit den Anschlüssen parallel zur Prüftaste extern beschaltbare Anwendungsmöglichkeiten geschaffen werden, die ebenfalls durch die Fehlerstromerzeugung, bei angeschlossener geschlossener Verwendung eines potentialfreien Kontaktes den Fehlerstrom-Schutzschalter auslösen.The invention achieves the creation of externally connectable application options with the connections parallel to the test button, which also trigger the residual current circuit breaker through the generation of residual current when a potential-free contact is connected and closed.

Eine vorteilhafte Ausgestaltung der Erfindung ist in Schutzanspruch 2 angegeben.An advantageous embodiment of the invention is specified in claim 2.

Die Weiterbildung nach Schutzanspruch 2 für externe Anwendungen ermöglicht Benutzern eine von extern ausgelöste Abschaltung der Stromkreise des Fehlerstrom-Schutzschalters für den Gefahrenfall bzw. für Prüfzwecke.The further development according to protection claim 2 for external applications enables users to externally switch off the circuits of the residual current circuit breaker in the event of danger or for testing purposes.

Ausführungsbeispiele der Erfindung werden wie folgt erläutert:Embodiments of the invention are explained as follows:

Parallel zur Prüftaste, des Fehlerstromschutz-Schalters, sind die beiden Anschlüsse integriert, die zugänglich angeordnet sind und für externe Anwendungen zur Verfügung stehen. Werden beide Anschlüsse miteinander verbunden löst der Fehlerstrom-Schutzschalter aus bzw. lässt sich nicht einschalten, da ein Fehlerstrom produziert wird. Sind die Anschlüsse nicht miteinander verbunden lässt sich der Fehlerstrom-Schutzschalter einschalteaDie Prüflünktion durch die Prüftaste wird nicht beeinträchtigt.Drückt man diese erfolgt wie gehabt eine Auslösung, vorausgesetzt er ist Funktionsfähig.Parallel to the test button on the residual current device, the two connections are integrated, which are arranged in an accessible manner and are available for external applications. If both connections are connected to each other, the residual current device is triggered or cannot be switched on because a fault current is produced. If the connections are not connected to each other, the residual current device can be switched on. The test function is not affected by the test button. If you press this, the device is triggered as usual, provided it is functional.

Ein breites Anwendungsfeld lässt sich im Bereich der Sensoren, mit potentialfreiem Kontakt, erschliessen. Diese können bei Anschluss Gefahren rechtzeitiger erkennen und entsprechend einen Abschaltvorgang einleiten. Beispiele:A wide range of applications can be opened up in the area of sensors with potential-free contact. When connected, these can detect dangers in good time and initiate a shutdown process accordingly. Examples:

Eine Abdeckung einer Verteilung,die mit einem Näherungsschalter gesichert ist, wird von einem Nichtfachmann entfernt.Der potentialfeie Kontakt schliesst und es erfolgt eine Abschaltimg.A cover of a distribution board that is secured with a proximity switch is removed by a non-expert. The potential-free contact closes and the system is switched off.

Anschluss der Sicherung nicht entsprechend angezogen. Der Anschluss wird zum Verbraucher und es fangt an zu schmoren bzw. Rauchentwicklung.Der Rauchmelder mit potentialfreiem Kontakt spricht an und es erfolgt eine Abschaltung mit gleichzeitiger Ursachenbekämpfung.The fuse connection is not tightened properly. The connection becomes a consumer and it starts to smolder or develop smoke. The smoke detector with potential-free contact responds and the system is switched off while the cause is eliminated at the same time.

Die Gasleitung hat ein Leck. Entsprechender Sensor mit potentialfreiem Kontakt spricht an, Strom wird abgeschalten und es kommt zu keiner Explosion wenn jemand versucht zu klingeln.The gas line has a leak. The corresponding sensor with a potential-free contact is activated, the power is switched off and there is no explosion when someone tries to ring the bell.
