Kombinierter Fehlerstromschutz- und LeitungsschutzschalterCombined residual current circuit breaker and line circuit breaker

Die Erfindung betrifft einen kombinierten Fehlerstromschutz- und Leitungsschutzschalter, dessen einzelnen Polen Magnetauslöser für Kurzschlußauslösung zugeordnet sind und der mit einer elektronischen Verstärkung zum Auslösen im Fehlerstromfall arbeitet.The invention relates to a combined residual current device and line circuit breaker, its individual Poles are assigned to magnetic release for short-circuit release and to the with an electronic amplification Tripping in the event of a fault current works.

Bei einem solchen auf dem Markt befindlichen Schutzschalter ist zur Auslösung im Fehlerstromfall ein zusätzliches Relais erforderlich, das über einen elektronischen Verstärker angesteuert wird. Allgemein kann man bei einem solchen Schutzschalter dann entweder über ein Schaltschloß alle Schaltkontakte öffnen oder auf ein Schaltkontaktpaar einwirken und die Schaltkontaktpaare der weiteren Pole über eine mechanische Kopplung öffnen. Hierbei werden außer dem gesonderten Relais weitere Bauteile für die Einwirkung auf das Schaltschloß bzw. für die Kopplung benötigt. Solche Maßnahmen benötigen außerdem zusätzlichen Raum, was sich in aufwendigeren Gehäusen niederschlägt.In such a circuit breaker on the market an additional relay is required for tripping in the event of a fault current, via an electronic Amplifier is controlled. In general, one can then either use a switch lock with such a circuit breaker open all switching contacts or act on one switching contact pair and the switching contact pairs of the others Open the pole via a mechanical coupling. In addition to the separate relay, additional components for the action on the switch lock or required for the coupling. Such measures also require additional Space, which is reflected in more complex housings.

Der Erfindung liegt die Aufgabe zugrunde, einen kombinierten Schutzschalter der eingangs geschilderten Art so weiter zuentwickeln, daß man-mit weniger Bauteilen und mit geringerem Raum auskommt.The invention is based on the object of providing a combined circuit breaker of the type described above to develop that one-with fewer components and with requires less space.

Die Lösung der geschilderten Aufgabe besteht darin, daß der Magnetauslöser mit zwei Wicklungen versehen ist: einer ersten Wicklung, die in den Leitungszug der zu über-The solution to the problem described is that the magnetic release is provided with two windings: one first winding, which is in the cable run of the

wachenden Leiter eingeschaltet ist und einer zweiten Wicklung, die an den Verstärkerausgang angeschlossen ist. Dadurch wird der ohnehin erforderliche Magnetauslöser doppelt genutzt und es erübrigt sich ein zusätzliches Relais zum Auslösen im Fehlerstromfall. Ein solcher Schutzschalter läßt sich wegen des eingesparten zusätzlichen Relais füf die Fehlerstromauslösung in einem geringeren Gehäusevolumen unterbringen.guarding conductor is switched on and a second winding that is connected to the amplifier output. Through this the magnetic release, which is required anyway, is used twice and an additional relay is not required for tripping in the event of a fault current. Such a circuit breaker can be saved because of the additional relay For the residual current release, place it in a smaller housing volume.

TO Die Erfindung soll anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden:TO The invention is intended to be based on an exemplary embodiment shown roughly schematically in the drawing explained:

Der kombinierte Schutzschalter 1 nach der Zeichnung weist einen Magnetauslöser 2 für Kurzschlußauslösung und einen elektronischen Verstärker 8 zum Auslösen im Fehlerstromfall auf. Die zu überwachenden Leiter, ein Außenleiter 3 und ein Neutralleiter 4 sind durch einen Summenstromwandler .5 durchgeführt. Im Ausführungsbeispiel ist also ein einpoliger Schutzschalter veranschaulicht.The combined circuit breaker 1 according to the drawing has a magnetic release 2 for short-circuit tripping and a electronic amplifier 8 for triggering in the event of a fault current. The conductors to be monitored, an outer conductor 3 and a neutral conductor 4 are carried out by a summation current transformer .5. In the exemplary embodiment is therefore a single pole circuit breaker illustrated.

Der Magnetauslöser 2 ist mit zwei Wicklungen versehen, einer ersten Wicklung 6, die in den Leitungszug der zu überwachenden Leiter, des Außenleiters 3 und des Neutralleiters 4, eingeschaltet ist. Eine zweite Wicklung 7 des Magnetauslösers 2 ist an den Verstärkerausgang 18 angeschlossen. The magnetic release 2 is provided with two windings, a first winding 6, which is in the cable run to monitoring conductor, the outer conductor 3 and the neutral conductor 4, is switched on. A second winding 7 of the Magnetic release 2 is connected to the amplifier output 18.

Der Anker 9 des Magnetauslösers 2 steht mit einem Schaltschloß 10 über Verbindungsmittel 11 in Eingriffverbindung. Wenn das Schaltschloß 10 entklinkt wird, werden die Schaltkontaktvorrichtungen 12 und 13 über die Verbindung 11 geöffnet. Jede der Schaltkontaktvorrichtungen kann ein Festkontaktstück und ein bewegliches Kontaktstück aufweisen. Im Ausführungsbeispiel ist mit einemThe armature 9 of the magnetic release 2 is in engagement connection with a switch lock 10 via connecting means 11. When the switch lock 10 is unlocked, the switch contact devices 12 and 13 are connected via the connection 11 open. Each of the switching contact devices can have a fixed contact piece and a movable contact piece exhibit. In the exemplary embodiment is with a
