Abstract

The invention relates to a circuit breaker (1) that is designed to be added to an auxiliary device with auxiliary functions, such as a residual current operated device or an undervoltage circuit breaker. Said auxiliary device brings about a switch-off coupling by means of a catch (2). Said circuit breaker comprises a zone of latching between a latch (3) and a trip lever (4). According to the invention, the catch (2), in a switch-off position of the auxiliary device, directly or indirectly displaces a spacer element (5) that spaces the latch (3) apart from the trip lever (4) and prevents the latching.

Description

Die Erfindung bezieht sich auf eine Schutzschalteinrichtunggemäß dem Oberbegriff des Anspruchs 1 (US 3,973,230).The invention relates to a protective switching device according to the preamble of claim 1 (US 3,973,230).

Bei einer Anreihung eines Fehlerstromschutzschalters an einer Schutzschalteinrichtung, beispielsweise in der Ausprägung als Leitungsschutzschalter, ist sicherzustellen, daß die Schutzschalteinrichtung nicht eingeschaltet werden kann, wenn der Fehlerstromschutzschalter nicht eingeschaltet und somit aktiviert ist. Bei vielen auf dem Markt befindlichen Geräten erlaubt man eine gewisse Annäherung der Kontakte der Schutzschalteinrichtung, bevor sie dann bei einem angekoppelten Fehlerstromschutzschalter in Ausschaltstellung durch ein entklinkendes Schaltschloß wieder auseinanderlaufen.If a residual current circuit breaker is connected to one Protective switching device, for example in the form of Miniature circuit breaker, make sure that the circuit breaker cannot be switched on if the Residual current circuit breaker not switched on and therefore activated is. Allowed for many devices on the market a certain approximation of the contacts of the protective switching device, before being coupled to one Residual current circuit breaker in the off position by a unlatching Switch lock diverge again.

Der Erfindung liegt die Aufgabe zugrunde, eine koppelbare Schutzschalteinrichtung zu entwickeln, bei der bei einem angereihten Fehlerstromschutzschalter in Ausschaltstellung bei einem Einschaltversuch der Schutzschalteinrichtung eine Annäherung der Kontakte unterbleibt.The invention has for its object a couplable To develop protective switching device in the case of a Residual current circuit breaker in the off position at an attempt to switch on the protective switching device the contacts are omitted.

Die Lösung der geschilderten Aufgabe erfolgt durch eine Schutzschalteinrichtung nach Anspruch 1.The described task is solved by a Protective switching device according to claim 1.

Bei einem angereihten Fehlerstromschutzschalter in Ausschaltstellung und dem Versuch, die Schutzschalteinrichtung einzuschalten, wird eine Annäherung der Kontakte verhindert. Dadurch vermeidet man eine mögliche Gefährdung durch einen Kontaktüberschlag. Die Schutzschalteinrichtung soll verständlicherweise bei einem angereihten Fehlerstromschutzschalter, der ausgelöst hat und in die Ausschaltstellung überführt wurde, verhindern, daß über die gekoppelte Schutzschalteinrichtung eine Wiedereinschaltung möglich ist. Bei einem Wiedereinschaltversuch unterbleibt eine Annäherung der Kontakte. With a connected residual current circuit breaker in the off position and trying to switch on the protective switching device, an approach of the contacts is prevented. Thereby one avoids a possible danger from a contact rollover. The protective switching device should understandably with a connected residual current circuit breaker, which has tripped and been switched to the off position, prevent over the coupled circuit breaker reactivation is possible. When trying to restart the contacts do not approach each other.

Ein günstiger Aufbau der Schutzschalteinrichtung mit einem Mitnehmer, der ein gesondertes Distanzelement in seiner Bewegung führt, wird durch ein Schaltschloß mit folgendem Aufbau gefördert: Seine Klinke führt in einem ortsveränderlichen Lager einen beweglichen Kontaktarm mittelbar oder unmittelbar. Der Auslösehebel ist in einem ortsfesten Lager angeordnet und stützt den beweglichen Kontaktarm in der Offenstellung des Handbedienorgans ab. Mit der Klinke ist eine Koppelstange zu einem verschwenkbaren Handbedienorgan in einem weiteren ortsveränderlichen Lager verbunden.An inexpensive construction of the protective switching device with one Driver, which is a separate spacer in its movement leads through a key switch with the following structure Funded: His jack leads in a portable warehouse a movable contact arm, directly or indirectly. The trigger lever is arranged in a fixed bearing and supports the movable contact arm in the open position of the Manual control unit. A coupling rod is closed with the jack a swiveling hand control in another portable one Warehouse connected.

Insbesondere kann das Distanzelement um das Lager für die Koppelstange drehbeweglich auf der Klinke angeordnet sein, wobei das Distanzelement in der Ausschaltstellung des Mitnehmers und in der Ausschaltstellung der Schutzschalteinrichtung gegen den Auslösehebel ansteht und eine Verklinkung verhindert.In particular, the spacer element around the bearing for the Coupling rod can be rotatably arranged on the pawl, the spacer element in the off position of the driver and in the off position of the protective switching device is against the release lever and prevents latching.

Nach einer Weiterbildung ist der Mitnehmer bei dem zuvor geschilderten Schaltschloß außerhalb der geometrischen Orte von Koppelstange und Klinkenlagerung angeordnet.After further training, the driver is with the previously described Switch lock outside the geometric locations of Coupling rod and pawl bearing arranged.

Vorteilhaft kann der Mitnehmer einen Exzenter bilden, der das Distanzelement auslenkt, wobei dieses als zweiarmiger Hebel ausgebildet sein kann, dessen einer Arm gegen den Auslösehebel distanzgebend anstehen kann, und auf dessen anderen Arm in der Ausschaltstellung eines Fehlerstromschutzschalters der Mitnehmer auslenkend einwirkt.The driver can advantageously form an eccentric that Spacer deflects, this as a two-armed lever can be formed, one arm against the trigger lever can stand in line, and on his other arm in the off position of a residual current circuit breaker Driver acts deflecting.

Für eine hochmechanisierte Fertigung ist es vorteilhaft, die bei einer Schutzschalteinrichtung erforderlichen und üblichen Fehlerelemente als Blattfedern auszubilden. Derartige Blattfedern lassen sich gut mit hoher Geschwindigkeit in einer Fertigungslinie herstellen und auch montieren. Die beschriebene Schutzschalteinrichtung hat den weiteren Vorteil, daß sie zu auf dem Markt befindlichen Baureihen kompatibel ist.For a highly mechanized production, it is advantageous that with a protective switching device required and usual Form fault elements as leaf springs. Such leaf springs can be done well at high speed in one Establish and also assemble the production line. The one described Protective switching device has the further advantage that it is compatible with the series on the market.

    Nach einer Weiterbildung, wie sie in FIG 1 veranschaulicht ist, führt die Klinke 3 in einem ortsveränderlichen Lager 8 einen beweglichen Kontaktarm 9, und zwar im Ausführungsbeispiel unmittelbar. Der Auslösehebel 4 ist in einem ortsfesten Lager 10 angeordnet. Die Achse 10 des Auslösehebels 4 stützt den beweglichen Kontaktarm 9 in einer Teilausnehmung 11 nach FIG 4 in der Offenstellung des Handbedienorgans 13 ab. Die Klinke 3 ist über eine Koppelstange 12 zu einem verschwenkbaren Handbedienorgan 13 in einem weiteren ortsveränderlichen Lager der Klinke verbunden. Der Mitnehmer 2 führt im Ausführungsbeispiel nach FIG 1 ein gesondertes Distanzelement 5 hinsichtlich seiner Bewegung. Der bewegliche Kontaktarm 9 und ein feststehender Kontakt 15 bilden ein Kontaktpaar, das in der Praxis Kontaktstücke 16 aufweist.After further training, as illustrated in FIG 1 is, the pawl 3 in a portable bearing 8th a movable contact arm 9, in the exemplary embodiment right away. The trigger lever 4 is in a fixed position Bearing 10 arranged. The axis 10 of the trigger lever 4 is supported the movable contact arm 9 in a partial recess 11 4 from the open position of the manual control element 13. The Pawl 3 is pivotable via a coupling rod 12 Hand control 13 in another portable Bearing connected to the jack. The driver 2 leads in the embodiment 1, a separate spacer element 5 regarding his movement.
