Description
Die
Erfindung betrifft eine Kontaktanordnung für einen Fehlerstromschutzschalter
nach dem Oberbegriff des Anspruchs 1. Ein solcher Fehlerstromschutzschalter
ist aus der
Handelsübliche Fehlerstromschutzschalter besitzen eine Kontaktstelle für den Hin- und Rückleiter, einen Summenstromwandler, durch den der Hin- und Rückleiter als Primärwicklung hindurchgeführt ist, sowie eine Sekundärwicklung, die entweder direkt oder über eine Elektronik mit der Wicklung eines Auslösers verbunden ist, der über einen Stößel ein Schaltschloss betätigt, mit dem die Kontaktstellen bleibend geöffnet werden.Commercially available residual current circuit breaker own a contact point for the forward and return ladder, a summation current transformer through which the forward and return conductors as a primary winding passed through, as well as a secondary winding, either directly or via an electronics is connected to the winding of a trigger, which has a Plunger a switch lock actuated, with which the contact points are permanently opened.
Aus bestimmten Gründen ist es notwendig, einen Fehlerstromschutzschalter regelmäßig auf seine Funktionssicherheit zu prüfen. Zu diesem Zweck besitzt er einen Prüfstromkreis zwischen dem Hin- und Rückleiter, in dem sich ein Prüfwiderstand sowie ein mittels einer Prüftaste betätigbarer Schalter befinden. Durch Schließen des Schalters wird ein Fehlerstrom simuliert, der über die Sekundärwicklung den Auslöser erregt, so dass dieser den Schalter abschaltet.Out certain reasons It is necessary to regularly install a residual current device to test its functional safety. For this purpose, he has a test circuit between the back and Return conductor, in which a test resistor as well as by means of a test button actuated Switch are located. By closing of the switch, a fault current is simulated over the secondary winding the trigger energized, so that this turns off the switch.
Hierdurch wird der nachgeordnete Stromkreis, in dem sich Verbraucher befinden, abgeschaltet. Befinden sich in diesem nachgeschalteten Stromkreis bestimmte Datenverarbeitungsanlagen, in denen Daten gespeichert sind, so kann es vorkommen, dass bei, wenn auch nur kurzzeitigen, Wegfall der Stromversorgung die Speicher gelöscht sind. Es ist daher erforderlich, den Fehlerstromschutzschalter so auszubilden, dass bei einer Prüfung eine Stromunterbrechung verhindert ist.hereby becomes the downstream circuit where consumers are located off. Are in this downstream circuit certain data processing equipment in which data is stored are, it may happen that, albeit briefly, Elimination of power supply the memory are cleared. It is therefore necessary the fault current circuit breaker in such a way that during a test a Power interruption is prevented.
Dies gilt um so mehr bei Fehlerstromschutzschaltern, bei denen die Prüfung automatisch erfolgt. In den Fällen einer automatischen Prüfung bliebe der Fehlerstromschutzschalter in der Ausschaltstellung, so dass nachgeschaltete Verbraucher, wie beispielsweise Kühlschränke oder Tiefkühltruhen und dgl., für längere Zeit nicht mehr mit Strom versorgt werden. Welche Probleme dies mit sich bringt, liegt auf der Hand.This This applies even more to residual current circuit breakers where the test is automatic he follows. In the cases an automatic test the fault current circuit breaker would remain in the off position, so that downstream consumers, such as refrigerators or Freezers and the like, for a long time no longer be supplied with electricity. What problems with this brings, is obvious.
Die
In
der Patentanmeldung
Der Hauptkontaktstelle, die den Strom normalerweise führt, ist ein Parallelzweig zugeordnet, in dem sich eine Nebenkontaktstelle befindet, die im Prüffall geschlossen wird, bevor die Hauptkontakte öffnen. Auf diese Weise fließt Strom durch den Parallelzweig und ein nachgeschalteter Verbraucher bezieht weiterhin Strom.Of the Main contact point, which carries the current normally, is assigned a parallel branch, in which a secondary contact point located in the test case is closed before the main contacts open. This is how electricity flows by the parallel branch and a downstream consumer relates continue electricity.
Diesem Verfahren haftet der Nachteil an, dass man den Prüfbypass nicht als Zusatzgerät parallel zu den Eingangs- und Ausgangsklemmen eines FI-Schalters schalten kann, da man damit den sich in seinem Inneren befindenden Summenstrom wandler, mit dem man den Fehlerstrom detektiert, kurzschließt.this Procedure adheres to the disadvantage that one the test bypass not as an accessory parallel to the input and output terminals of a residual current circuit breaker can switch, because you are with it inside him Summation current transformer, with which one detects the fault current short-circuits.
Aufgabe der Erfindung ist es, eine Kontaktanordnung für einen Fehlerstromschutzschalter anzugeben, mittels der eine unterbrechungsfreie Überprüfung des Fehlerstromschutzschalters auf vorteilhafte Art und Weise möglich ist.task The invention is a contact arrangement for a residual current circuit breaker indicate, by means of an uninterrupted check the residual current circuit breaker possible in an advantageous manner is.
Die Aufgabe wird durch eine Kontaktanordnung gemäß dem Patentanspruch 1 gelöst.The The object is achieved by a contact arrangement according to the patent claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Further developments of the invention are the subject of the dependent claims.
Die Sekundärwicklung des obengenannten Wandlers erhält zwei zusätzliche Anzapfungen bzw. Anschlüsse, eine am Eingang, die andere am Ausgang der Wicklung. Einen Anschluss verbindet man mit dem Nulleiter N, den anderen über einen Widerstand und einen Schalter (Taster) mit der Phase L.The secondary winding of the above converter two additional ones Taps or connections, one at the entrance, the other at the exit of the winding. A connection one connects with neutral N, the other with resistance and one Switch (button) with the phase L.
Den Bypass-Schalter, der sowohl den Nulleiter, als auch den Phasenleiter des FI-Schalters überbrückt, kann man nunmehr einfach an die Eingangs- und Ausgangsklemmen des FI-Schalters anschließen. Man benötigt lediglich noch eine zusätzliche Steckverbindung.The Bypass switch, which both the neutral conductor, and the phase conductor of the FI-switch can bypass one now simply to the input and output terminals of the FI-switch connect. You need only one additional connector.
Die in dem FI-Schalter üblicherweise angeordnete Prüftaste löst bei Betätigung den Schalter nicht mehr aus.The in the FI-switch usually arranged test button dissolves activity the switch no longer off.
Drückt man jedoch die Prüftaste des Bypass-Schalters, so fließt unabhängig von den Primärleitungen des Summenstromwandlers des FI-Schalters ein Strom durch die Sekundärwicklung des Wandlers und löst dadurch den Auslöser und das Schaltwerk des FI-Schalters aus.You press however, the test button of the bypass switch, so flows independently from the primary lines of the summation current transformer of the FI-switch, a current through the secondary winding of the converter and releases thereby the trigger and the rear derailleur of the FI-switch off.
Anschließend muß man das FI-Schaltwerk wieder ein- und das des Bypasses ausschalten.Then you have the Switch on the FI rear derailleur and switch off the bypass.
Selbstverständlich kann man mit herkömmlichen Mitteln diese Vorgänge automatisch ablaufen lassen.Of course you can one with conventional ones Means these operations run automatically.
An einem Ausführungsbeispiel sei die Erfindung näher erläutert.At an embodiment let the invention be closer explained.
