Description

Die bisher bekannten Schaltgeräte für Einphasenmotoren mit Hilfs- lind Hauptwicklung haben einen begrenzten Verwendungszweck oder sind kompliziert und teuer.The previously known switching devices for single-phase motors with auxiliary and main windings have limited uses or are complicated and expensive.

Es wird nun gemäß der Zeichnung ein Schaltgerät neuer Konstruktion vorgeschlagen, «-elches im Aufbau einfach, sicher und klein ist, und für Motoren mit Hilfs- und Hauptwicklung jederzeit Verwendung finden kann.It is now a switching device of new design according to the drawing suggested «-which is simple, safe and small in construction, and for engines with auxiliary and main winding can be used at any time.

Die Zeichnung stellt das Schaltbild des Schaltgerätes für einen Einphasenwechselstrommotor mit Hilfs- und Hauptwicklung dar. Die Umrandung deutet das Schaltgerät mit kombinierter Sicherung an.The drawing represents the circuit diagram of the switching device for a single-phase AC motor with auxiliary and main winding. The border indicates the switching device with combined Fuse on.

Die Arbeitsweise dieses Gerätes ist folgende: Wenn der Schalter g geschlossen wird, fließt über die Arbeitswicklung 6 des Motors und die Relaiswicklung 3, Kontakt z und Thermosicherung i das Zweieinhalb- bis Fünffache des Nennstromes der Hauptwicklung. Dieser hohe Strom tritt auch in der Relaiswicklung 3 auf und zieht dadurch den Anker e, welcher im Ruhezustand durch die Feder f am Anschlag ä gehalten wird, an. Die Kontakte .4 und 5 kommen zusammen und sind über den federnd gleitenden oder festen Kern b vor der Relaisspule 3 und über den Kontakt 2 zur Hilfswicklung 7 des Motors verbunden. Jetzt kann der Motor sein Drehfeld entwickeln und der Strom der Hauptwicklung6 fällt ab auf den Wert des Nennstromes. Die Feder f zwingt den Anker e, die Verbindung über die Kontakte 5 und 4. zur Hilfsphase zu lösen, und nun geht der Anker e in Grundstellung g zurück. Wird die nun laufende Maschine über das zulässige Maß des Nennstromes belastet, wobei die Drehzahl abnimmt, dann wird der Anker e wieder angezogen und schaltet die Hilfswicklung zu, damit die normale Drehzahl erreicht wird.This device works as follows: When switch g is closed, flows through the working winding 6 of the motor and the relay winding 3, contact z and thermal fuse i two and a half to five times the nominal current the main winding. This high current also occurs in the relay winding 3 and thereby pulls the armature e, which in the idle state by the spring f on the stop ä is held on. The contacts .4 and 5 come together and are resilient over the sliding or fixed core b in front of the relay coil 3 and via the contact 2 to the auxiliary winding 7 of the motor connected. Now the motor can develop its rotating field and the current the main winding6 drops to the value of the nominal current. The spring f forces the Anchor e to release the connection via contacts 5 and 4. to the auxiliary phase, and now the anchor e goes back to the basic position g. Will the now running machine over the permissible level of the rated current is loaded, with the speed decreasing, then becomes the armature e is attracted again and switches on the auxiliary winding, so that the normal Speed is reached.

Der in der Zeichnung gezeigte Anschlag c bringt den Anker e im Ruhezustand näher oder weiter an den Kern b, und es wird dadurch auch die Feder f gespannt. Dies bedeutet, daß dadurch das Relais für mehrere Motorenstärken verwendet werden kann und die Lagerhaltung reduziert wird. Auch läßt sich durch den Anschlag c die Empfindlichkeit des Relais weitgehend regulieren.The stop c shown in the drawing brings the armature e to rest closer or further to the core b, and the spring f is thereby also tensioned. This means that the relay can be used for several engine strengths can and storage is reduced. Also can by the stop c the Regulate the sensitivity of the relay as far as possible.

Die mit dem Relais kombinierte Merstromsicherung 1, 2 und a. schützt bei einer längeren überstrombelastung die Hilfs- und Hauptwicklung des Motors, da auch die Überstromsicherung dem Relais und der Hilfs- und Hauptwicklung des Motors vorgeschaltet ist.The Merstromsicherung 1, 2 and a combined with the relay. protects in the event of a longer overcurrent load, the auxiliary and main windings of the motor, there also the overcurrent protection of the relay and the auxiliary and main winding of the motor is upstream.

Das Neue der vorgeschlagenen Konstruktion besteht auch darin, daß die Kontakte zum Funkenschutz innerhalb der Relaisspule schalten. Ferner sind Schaltgerät und Sicherungselement zusammengebaut, und sie sind an dem Klemmbrett eines Motors angebaut.The novelty of the proposed construction is also that switch the contacts for spark protection within the relay coil. There are also switching devices and fuse element assembled, and they are on the terminal board of a motor cultivated.

Es wird noch erwähnt, daß zur Sicherung der Flilfsphase allein noch ein thermischer Auslöser zwischen Anker e und die Leitung zur Hilfswicklung 7 des Motors gelegt werden kann.It is also mentioned that only to secure the filling phase a thermal release between armature e and the line to the auxiliary winding 7 of the Motor can be placed.
