Abstract
Description
Die Erfindung betrifft eine Prüfeinrichtung für Fehlerstromschutzschalter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a test device for residual current circuit breakers according to the preamble of claim 1.
Eine derartige Prüfeinrichtung, die aus der DE-PS 26 18 295 bekannt geworden ist, wird bei Fehlerstromschutzschaltern benötigt, um die Funktionssicherheit und -bereitschaft des Fehlerstromauslösers zu prüfen. Dies wird dadurch erreicht, daß über einen Prüfwiderstand von einer Phase zur anderen, unter Umgehung des Summenstromwandlers, ein Strompfad, nämlich der Hilfsstromkreis, beim Drücken der Prüftaste geschlossen wird. Es handelt sich hierbei um einen nachgeahmten Fehlerstrom, der den Auslöser des Fehlerstromschutzschalters zum Ansprechen bringt und damit den Mechanismus des Fehlerstromschutzschalters entklinkt.Such a test device, which has become known from DE-PS 26 18 295, is required in the case of residual current circuit breakers in order to test the functional reliability and readiness of the residual current release. This is achieved by closing a current path, namely the auxiliary circuit, via a test resistor from one phase to another, bypassing the summation current transformer, when the test button is pressed. This is an imitated fault current that triggers the release of the residual current circuit breaker and thus unlatches the mechanism of the residual current circuit breaker.
Ein Fehlerstromschutzschalter, der zum Schließen eines Prüfstromkreises eine Prüftaste aufweist, mit deren Hilfe ein den Auslöser des Fehlerstromschutzschalters zum Ansprechen bringender nachgeahmter Fehlerstrom einschaltbar ist, ist aus der DE-PS 27 33 837 bekannt. Hierbei wird das Gegenkontaktstück des Schalters für den Prüfstromkreis durch ein Teil des Schaltschlosses gebildet, das beim Auslösen des Schaltschlosses aus dem Wirkbereich eines Schenkels der Schenkelfeder heraus schwenkt.A residual current circuit breaker which has a test button for closing a test circuit, with the aid of which a mimicked fault current triggering the trigger of the residual current circuit breaker can be switched on, is known from DE-PS 27 33 837. Here, the counter contact piece of the switch for the test circuit is formed by a part of the switch lock, which pivots out of the effective range of a leg of the leg spring when the switch lock is triggered.
Bei den zuvor genannten Fehlerstromschutzschaltern ist es nicht eindeutig erkennbar, welche Stellung die Hauptkontakte jeweils haben. Aus der Stellung des Einschalthebels läßt sich nur die angenäherte Stellung erkennen.With the aforementioned residual current circuit breakers, it is not clearly recognizable which position the main contacts have. Only the approximate position can be seen from the position of the switch lever.
In der EP 0 231 732 wird ein Fehlerstrom- und Leitungsschutzschalter mit einem Schalter für einen Mittelleiter beschrieben, bei dem die bewegliche Schaltbrücke (Schaltelement) des in einem Gehäuseteil angeordneten Leitungsschutzschalters mit dem beweglichen Kontaktarm des in einem weiteren Gehäuseteil aufgenommenen Schalters für den Mitteleiter über einen an einer Gehäusezwischenwand geführten Schieber gekoppelt ist. Der Schalter weist eine Kontaktstellungsanzeigevorrichtung und eine Prüfeinrichtung auf, die beide durch diesen Schieber betätigbar sind. Der Schieber bewegt die Kontaktstellungsanzeigevorrichtung so, daß die jeweilige Schaltstellung des FI/ LS-Schalters durch ein Fenster im Gehäuse angezeigt wird. Zur Betätigung der Prüfeinrichtung ist der Schieber mit dem einem Schenkel einer zu dieser gehörenden Prüfkontaktfeder gekoppelt, der einem Prüfkontakt zugeordnet ist, derart, daß der Schenkel in der "Aus"-Schaltstellung vom Prüfkontakt abgehoben und der Prüfstromkreis unterbrochen und auch bei Betätigung einer auf den zweiten Schenkel wirkenden Prüftaste nicht schließbar ist, und in der "Ein"-Schaltstellung am Prüfkontakt anliegend angeordnet und der Prüfstromkreis durch Betätigung der Prüftaste schließbar ist.EP 0 231 732 describes a residual current and line circuit breaker with a switch for a center conductor, in which the movable switching bridge (switching element) of the line circuit breaker arranged in one housing part with the movable contact arm of the switch for the center conductor accommodated in another housing part via a is coupled to a partition wall guided slide. The switch has a contact position indicator and a test device, both of which can be actuated by this slide. The slide moves the contact position display device so that the respective switching position of the FI / LS switch is indicated by a window in the housing. To actuate the test device, the slide is coupled to the one leg of a test contact spring belonging to it, which is assigned to a test contact, such that the leg is lifted from the test contact in the "off" switch position and the test circuit is interrupted and also when one is actuated on the second leg acting test button is not closable, and arranged in the "on" switch position adjacent to the test contact and the test circuit can be closed by pressing the test button.
Der Erfindung liegt nun die Aufgabe zugrunde, eine Prüfeinrichtung für Fehlerstromschutzschalter der zuvor geschilderten Art zu entwickeln, die sich mit einer Kontaktstellungsanzeigevorrichtung auf kleinem Raum kombinieren läßt, und daß Teile sowohl der Prüfeinrichtung als auch der Kontaktstellungsanzeigevorrichtung für beide Funktionen ausgebildet sind.The invention is based on the object of a test device to develop for residual current circuit breakers of the type described above, which can be combined with a contact position indicator in a small space, and that parts of both the test device and the contact position indicator are designed for both functions.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebene Kombination von Merkmalen gelöst.This object is achieved according to the invention by the combination of features specified in the characterizing part of claim 1.
Die mit der Erfindung erzielten Vorteile bestehen darin, daß der Aufwand an Teilen für die Funktionen "Hilfsstromkreis" und "Kontaktstellungsanzeige" vermindert werden konnte, womit der Einsatz mit diesen Funktionseinheiten in Fehlerstromschutzschaltern in Schmalbauweise ermöglicht wird. Vorteilhafterweise wird bei der Kombination der Prüfeinrichtung mit einer Kontaktstellungsanzeigevorrichtung eine Biegefeder, welche die Kontaktstellungsanzeigevorrichtung betätigt, gleichzeitig als schaltstellungsabhängiges Kontaktelement genutzt.The advantages achieved by the invention consist in the fact that the expense of parts for the functions "auxiliary circuit" and "contact position indicator" could be reduced, which enables the use with these functional units in residual current circuit breakers in a narrow construction. Advantageously, when the test device is combined with a contact position display device, a spiral spring which actuates the contact position display device is simultaneously used as a switch position-dependent contact element.
Vorteilhafte Weiterbildungen des Gegenstandes nach Anspruch 1 sind den Unteransprüchen zu entnehmen.Advantageous developments of the subject matter according to claim 1 can be found in the subclaims.
