Description

Thermische Relais mit einem aus Bimetall od. dgl. bestehenden Schaltorgan in Form einer Kippfeder sind bekannt. Die vorliegende Erfindung hat sich die Aufgabe gestellt, derartige Relais so auszubilden, daß sie die Hilfsphase eines Einphaseninotors in einer vorgeschriebenen Zeit sicher ausschalten und dabei möglichst wenig von der Stromstärke des 'Motors hinsichtlich der Schaltzeit heeinfluß werden.Thermal relay with a bimetal or the like. Existing switching element in the form of a toggle spring are known. The present invention has the task made to train such relays so that they the auxiliary phase of a Einphaseninotors Switch off safely in a prescribed time and at the same time as little as possible of the amperage of the 'motor with regard to the switching time will be influenced.

Gemäß der Erfindung wird dies dadurch erzielt, (Maß da: Relais mit einer Zusatzheizung versehen ist, die gleichzeitig mit der Hilfsphasenwicklung des Motors abgeschaltet wird. Außerdem ist eine vom Strom der Hauptphasenwicklung durchflossene Hauptheizwicklung vorgesehen, die durch entsprechend geringe Wärmezufuhr dafür sorgt, daß (las Schaltorgan während des Betriebes des Motors ausgeschaltet bleibt. Ein derartiges Relais eignet sich besonders für die Schaltung von Motoren zum -Antrieb von Kältemaschinen.According to the invention, this is achieved by (measure there: relay with an additional heater is provided, which simultaneously with the auxiliary phase winding of the Motor is switched off. In addition, there is one through which the current from the main phase winding flows Main heating winding is provided, which ensures, through a correspondingly low heat input, that (read switching element remains switched off during operation of the engine. On Such a relay is particularly suitable for switching motors to drive of chillers.

In der Figur ist die Erfindung an einem Ausführungsbeispiel erläutert. Das Schaltorgan des Relais besteht aus einer Blattfeder i, die in der 'litte durch die Schraube a eingespannt ist und die beiden Kontakte 3 und .I, trägt. Im Gehäuse 5 des Relais ist eine "Zusatzheizung 6 vorgesehen, die so angeordnet ist, daß sie gleichzeitig mit der Hil'fsp'hasenwick@ung 7 des 'Motors abgeschaltet wird. Wird also der 'Motor eingeschaltet, so sind durch die Kontakte 3 uttd 4 des Schaltotrgarts i die Kontakte 8 und 9 überbrückt, und der Motor kann anlaufen. Nach eitler vorgeschriebenen Zeit, entsprechend welcher der Zusatzwiderstand 6 bemessen ist, wird durch die Wärmeeinwirkung dieses Widerstandes 6 das Schaltorgan t von den Kontakten und 9 abgehoben und hierdurch die Hilfsphase abgeschaltet. Gleichzeitig mit der Abschaltung der Hilfsphase wird auch der Widerstand 6 stromlos.In the figure, the invention is explained using an exemplary embodiment. The switching element of the relay consists of a leaf spring i, which is in the 'litte through the screw a is clamped and the two contacts 3 and .I carries. In the case 5 of the relay is an "auxiliary heater 6 is provided, which is arranged so that it is switched off at the same time as the auxiliary phase winding 7 of the motor. Will So the 'motor is switched on, so are through the contacts 3 uttd 4 of the switchgear i bridged contacts 8 and 9 and the motor can start. According to vain prescribed The time, according to which the additional resistor 6 is dimensioned, is determined by the action of heat this resistor 6, the switching element t lifted from the contacts and 9 and thereby the auxiliary phase is switched off. Simultaneously with the shutdown of the auxiliary phase also the resistor 6 is de-energized.

Außerdem ist in dem Gehäuse > die Hauptheizwicklung io vorgesehen, die int Stromkreis der Hauptphasenwicklung i t liegt ttnd durch entsprechend geringere Wärmezufuhr dafür sorgt, daß (las Schaltorgan i während de: 1)etriel)es des Motors ausgeschaltet '>leiht.In addition, the main heating winding io is provided in the housing, the int circuit of the main phase winding i t lies ttnd through correspondingly lower ones Heat supply ensures that (las switching element i during de: 1) etriel) it of the motor turned off '> borrows.
