Description

Es ist bereits vorgeschlagen «-orden, bei elektrischen Wechselstromschaltern Synchronsteuerungen zu verwenden, die aus einem vom Abschaltstrom beeinflußten Haltemagneten bestehen, der so ausgebildet ist. daß er eine große Haltekraft, aber eine geringe Fernwirkung aufweist. Infolgedessen wird der Anker bis zum Auslösezeitpunkt von der Haltemagnetisierting sicher festgehalten und erst beim Nulldurchgang des Stromes losgelassen, ohne daß der Anker von der dann wieder anwachsendenMagnetisierung zurückgeholt wird.It has already been suggested for AC electrical switches To use synchronous controls that consist of a holding magnet influenced by the cut-off current exist, which is so designed. that he has a great holding power, but a low one Has a long-range effect. As a result, the armature is until the tripping time of the holding magnetization is securely held and only when the current crosses zero released without the armature being brought back from the magnetization which then increases again will.

Da die Haltemagnetisierung durch den Abschaltstrom beeinflußt wird, so würde die Synchronsteuereinrichtung fortwährend ansprechen, was natürlich unerwünscht ist. Aus diesem Grunde wird bei den bereits vorgeschlagenen Anordnungen eine Sperrung für den Anker im Schaltermechanismus vorgesehen, durch welche der Anker arretiert und erst im Ansprechfalle freigegeben wird. Hiermit ist aber eine Komp:lizierung der Schalterausbildung an sich verbunden. Außerdem läßt sich diese Art der Arretierung nicht immer anwenden.Since the holding magnetization is influenced by the switch-off current, so the synchronous control device would respond continuously, which of course is undesirable is. For this reason, the arrangements already proposed are blocked provided for the armature in the switch mechanism through which the armature is locked and is only released in the event of a response. But this is a complication connected to the switch training itself. This type of locking can also be used do not always apply.

Die Erfindung vermeidet diesen 'Nachteil. Sie betrifft eine Synchronsteuereinrichtung mit einem Haltemagneten gr01"#er Haltekraft. aber geringer Fernwirkung und besteht darin. daß mit der Erregerwicklung des Haltemagneten die Spule eines Auslösemagneten in Reihe geschaltet ist, der der Betätigung einer Verklinlzung dient, durch welche der Anker des: Haltemagneten im angezogenen Zustand fest an die Halteflächen des Magneten angedrückt und in dieser Lage festgehalten wird. Beide Spulen werden vorzugsweise vorn Laststrom durchflossen. Die erfindungsgemäße Ausbildung ist von der Ausführung des gesteuerten Schaltermechanismus völlig unabhängig und bedingt außerdem ein genaues Arbeiten der Einrichtung.The invention avoids this disadvantage. It relates to a synchronous control device with a holding magnet greater holding power. but little effect from a distance and exists in this. that with the excitation winding of the holding magnet, the coil of a release magnet is connected in series, which is used to actuate a latching through which the armature of the: holding magnet firmly attached to the holding surfaces of the Magnet is pressed and held in this position. Both coils are preferred load current flowing through the front. The training according to the invention is of the execution of the controlled switch mechanism completely independent and also requires an accurate Works of establishment.

In der Zeichnung ist ein Ausfiihrungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

i ist ein Elektromagnet, dessen Erregerspulen z, die insbesondere als Scheibenspulen ausgebildet sind, vom Laststrom, beispielsweise über einen Stromwandler, durchflossen ,werden. Die Pole des 'Magneten i sind voneinander nur durch einen schmalen Spalt getrennt. so daß nach dem Abhelfen des Ankers 3 der größte Teil der Kraftlinien durch den Spalt hindurchtritt. Der Anker 3 besteht vorzugsweise aus nichtrostendem Eisen und liegt im angezogenen Zustand fest an die durch besondere Bearbeittin; möglichst glatt geschliffenen Halteflächen; des Haltema.gneten.i is an electromagnet whose excitation coils z, in particular are designed as disc coils, from the load current, for example via a current transformer, flowed through. The poles of the 'magnet i are separated from each other only by one separated by a narrow gap. so that after remedying the anchor 3 most of the Lines of force passing through the gap. The anchor 3 is preferably made of stainless iron and, when tightened, lies firmly on the special Processor; holding surfaces ground as smoothly as possible; of the holding device.

Der Ankerfortsatz .4 steht unter der Wirkung einer in dem Gehäuse C) untergebrachten Iiraftspeicherfeder 5. Unterhalb des Ankers 3 befindet sich eine besondere Haltevorrichtung B. Klinke us«-., die in der Zeichnung nur schematisch dargestellt ist. deren Auslösespule 9 gemäß der Erfindung mit den Erregerspulen des Haltemagneten in Reihe geschaltet ist. Sobald der Auslöseniagnet 9 die Verklinkung S des Ankers 3 freigegeben hat, läßt der Haltemagnet den =Imker im -Nulldurchgang des Stromes durch. Der Anker bewegt sich unter Federwirkung nach unten und leitet beispielsweise die Trennring von Schaltkontakten ein.The anchor extension .4 is under the action of a in the housing C) housed Iiraft storage spring 5. Below the armature 3 is a special holding device B. latch us «-., which in the drawing only schematically is shown. their trip coil 9 according to the invention with the excitation coils of the holding magnet is connected in series. As soon as the triggering device 9 the latching S of the armature 3 has released, the holding magnet leaves the beekeeper in -zero of the current through. The armature moves downwards under the action of a spring and conducts for example the separating ring of switch contacts.

In Abb. 2 ist die Reihenschaltung der Erregerspule 2 des Haltemagneten r mit der Erregerspule 9 des Auslösemagnetengezeigt, wobei der Anker 3 und die Auslösevorriclituntiur schematisch dargestellt sind.In Fig. 2 is the series connection of the excitation coil 2 of the holding magnet r shown with the excitation coil 9 of the tripping magnet, the armature 3 and the tripping device are shown schematically.
