Description

Durch Kraftspeicher betätigter elektrischer Schalter, der mit einer Sperrung gegen unberechtigtes Einschalten versehen ist Elektrische Schalter werden häufig mit Einrichtungen versehen, die ein Einschalten unter gewissen Bedingungen verhindern. -Man bringt zu dem Zweck z. B. auf der Schalterwelle eine Scheibe an, die mit einem Ausschnitt versehen ist, in den der als Riegel dienende Anker eines als Spannungsrückgangmagnet ausgebildeten Magneten einfällt. Ein Einschalten von Hand ist dadurch unmöglich gemacht. Die Sperrung genügt aber nicht bei Schaltern, die durch Einschaltmagnete oder Kraftspeicher betätigt werden, weil Gefahr besteht, daß diese mit großer Kraft arbeitenden Apparate die Sperrung oder den Schalter beschädigen. Bei Einschaltmagneten hat man sich dadurch geholfen, daß man durch den Sperrmagneten gleichzeitig einen Kontakt in dem Stromkreis des Einschaltmagneten öffnet und so die Betätigung dieses Magneten bei gesperrtem Schalterunmöglichmacht. Bei Kraftspeichern genügt es aber nicht, daß man in ähnlicher Weise mit dem den Kraftspeicher aufziehenden Motor verfährt, weil das Aufziehen und Auslösen des Kraftspeichers nicht unmittelbar aufeinanderfolgt, und weil außerdem der Kraftspeicher auch von Hand aufgezogen und ausgelöst werden kann.Electric switch operated by an energy store, which is connected to a Locking against unauthorized switching on is provided electrical switch often provided with devices that enable it to be switched on under certain conditions impede. - One brings for the purpose z. B. on a washer on the switch shaft, which is provided with a cutout in which the anchor serving as a bolt is inserted designed as a voltage drop magnet occurs. Switching on Hand is thereby made impossible. However, blocking is not sufficient for switches which are operated by solenoids or energy storage devices because there is a risk of that these devices, working with great force, damage the lock or the switch. With closing magnets you have helped yourself by going through the blocking magnet at the same time a contact in the circuit of the closing magnet opens and so makes it impossible to operate this magnet when the switch is locked. With lift mechanisms But it is not enough that one pulls up the energy storage device in a similar way The motor moves because the lift mechanism is not opened and released immediately one after the other, and because the energy storage mechanism is also pulled up by hand and can be triggered.

Erfindungsgemäß wird dieser Mangel dadurch behoben, daß man den Kraftspeicher selbst mit einer Sperreinrichtung versieht, die gleichzeitig mit der eigentlichen Schaltersperrung und unter Umständen durch den gleichen Sperrmagneten betätigt wird.According to the invention, this deficiency is remedied by the fact that the energy storage device Provides itself with a locking device, which is simultaneously with the actual Switch lock and may be operated by the same locking magnet.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Ein Ölschalter a kann vermittels des Handrades b oder vermittels des Kraftspeichers c eingeschaltet werden. Der Anker d wird gewöhnlich durch die Spule e hochgehalten. Wird diese Spule abgeschaltet, dann fällt der Anker in den Ausschnitt der auf der Schalterwelle f aufgekeilten Scheibe g, so daß das Einschalten vermittels des Handrades unmöglich wird. Der gespannt gezeichnete Kraftspeicher c wird durch die Klinke h in seiner Spannlage festgehalten. Wird diese Klinke von Hand oder durch eine nicht gezeichnete elektrische Vorrichtung in der Pfeilrichtung bewegt, so entlädt sich der Kraftspeicher auf den Ölschalter, den er dadurch einschaltet. Mit dem Anker d ist ein doppelarmiger Hebel i verbunden, der in der gezeichneten Stellung die Bewegung der Klinke nicht hindert, der aber nach Fallen des Sperrankers sich so vor die Klinke legt, daß sie nicht mehr bewegt werden kann.An exemplary embodiment is shown in the drawing. An oil switch a can be switched on by means of the handwheel b or by means of the energy store c will. The armature d is usually held up by the coil e. Will this coil switched off, then the armature falls into the cutout on the switch shaft f wedged washer g, so that switching on by means of the handwheel is impossible will. The tensioned energy storage mechanism c is by the pawl h in his Tension position held. Is this latch by hand or by a non-drawn one If the electrical device is moved in the direction of the arrow, the energy storage device is discharged on the oil switch, which it then switches on. With the anchor d is a double-armed Lever i connected, the movement of the pawl not in the position shown prevents it, but after the locking anchor has dropped, it lays down in front of the latch that it can no longer be moved.
