Description
Nullspannungs-Zeitauslöser für.Ölschalter Zum Auslösen von Ölschaltern bei Hochspannungsrückgang oder beim Ausbleiben der Spannung wurden bisher Nullspannungsmagnete mit Zeitauslösung verwendet, deren Verzögerung durch ein besonders getrennt vom Auslöser arbeitendes Relais bewirkt worden ist. , Man ist dann dazu übergegangen, nur einen Nullspannungsmagneten zu verwenden, mit dem gleichzeitig das Uhrwerk für die Zeitverzögerung verbunden ist. Bei einer solchen Anordnung muß@te aber der Anker einen verhältnismäßig langen Weg zurücklegen, ehe dieser die Klinkvorrichtung zur Betätigung der Freilaufkupplung am Schalter berührt hatte. In der Praxis sind diese Nullspannungsauslöser nur für leichte Schalter mit verhältnismäßig geringem Klinkendruck verwendbar.Zero-voltage time release for oil switch For triggering oil switches in the event of a drop in high voltage or if there was no voltage, zero-voltage magnets were previously used used with time release, the delay of which is separated by a special from Trigger working relay has been effected. 'You then went over to to use only one zero-voltage magnet, with which the clockwork for the time delay is connected. With such an arrangement, however, the anchor Cover a relatively long way before this the ratchet device to Had touched actuation of the overrunning clutch on the switch. In practice, these are Zero voltage release only for light switches with relatively low latch pressure usable.
Gemäß der Erfindung, welche im Ausführungsbeispiel dargestellt ist, werden nun die Nullspannungsauslöser derart ausgebildet, daß der Auslösehebel sowohl mit dem Winkelhebel eines regelbaren Zeitwerkes als auch mit dem Nullspannungsanker über eine Klinke mechanisch gekuppelt ist. Infolge der Schlagbewegung des Auslösehebels e, welche durch den Federkraftspeicher d bewirkt wird, kann auch der größte Klinkendruck überwunden werden. Der Nullspannungsmagnet läßt bei Spannungsrückgang den Anker a, der um den festen Punkt h drehbar ist, los und gibt die Klinke b und damit den Auslösehebel e frei. Die Kraftspeicherfederd versucht den Auslösehebel C nach unten zu ziehen, wird jedoch durch die Klinke" welche auf den Winkelhebel f wirkt, so lange daran gehindert, bis der Hebel f nach Ablauf des Uhrwerks g die Klinkee freigibt.According to the invention, which is shown in the exemplary embodiment, the zero voltage release are now designed in such a way that the release lever both with the angle lever of an adjustable timer as well as with the zero-voltage anchor is mechanically coupled via a pawl. As a result of the flapping movement of the release lever e, which is effected by the spring force accumulator d, can also use the greatest pawl pressure to be overcome. The zero-voltage magnet leaves the armature when the voltage drops a, which can be rotated around the fixed point h, and releases the pawl b and thus the Release lever e free. The energy storage spring tries the release lever C down to pull, however, by the pawl "which acts on the angle lever f, so prevented from doing so for a long time until the lever f releases the latch after the clockwork g has expired.
Erreicht innerhalb -einer bestimmten Zeit die Spannung ihre normale Höhe und liegt diese Zeit innerhalb der auf dem Uhrwerk eingestellten Grenze, so wird der Anker a wieder eingezogen und damit der Auslösehebel c durch die Klinke b in seine ursprüngliche Lage gebracht, ohne daß,eine Auslösung erfolgt ist.If the voltage reaches normal within a certain time Height and this time is within the limit set on the movement, see above the armature a is retracted and thus the release lever c by the pawl b brought into its original position without triggering.
