Description
Einrichtung nach Patent 359218 zur Bestimmung der Unterbrechungsfrequenz bei elektrischen Notorunterbrechern. Gegenstand' der Erfindung ist eine zur Wahrnehmbarmachung der Unterbrechungsfrequenz von elektrischen Motorunterbrechern dienende weitere Ausbildung der Einrichtung nach dem Hauptpatent. Die neue Einrichtung kann leicht an jedem bereits fertigen Motorunterbrecher nachträglich angebracht werden und bietet auch den Vorteil, unabhängig von dem Betriebsstrom sowohl des Unterbrechers als auch des ihn antreibenden Elektromotors zu sein.Device according to patent 359218 for determining the interruption frequency with electric notor breakers. The subject of the invention is one for making it perceptible the interruption frequency of electric motor breakers serving further Training of the facility according to the main patent. The new setup can be easy can be retrofitted to every already finished motor breaker and offers also the advantage regardless of the operating current of both the breaker and the also to be the driving electric motor.
Ein Ausführungsbeispiel der neuen Einrichtung ist zugleich mit ihrer Schaltungsanordnung in der Abbildung, in der Draufsicht auf dem Motorunterbrecher schematisch dargestellt. Der Stromunterbrecher a wird in der an sich bekannten Weise durch den Elektromotor b angetrieben, an dessen Achse nun gemäß der Erfindung der Kollektor c befestigt ist. Die Anzahl der -Kollektorlamellen d ist gleich der Anzahl der auf eine Umdrehung des Unterbrechers entfallenden, durch den Unterbrecher selbst herbeigeführten Stromunterbrechungen, also im allgemeinen gleich der Anzahl der vorhandenen Kontaktstücke .des Unterbrechers. Die auf dem Kollektor schleifenden Bürsten e sind unter Zwischenschaltung des Frequenzmessers f mit der (Gleichstrom-) Quelle, etwa dem Netz g, verbunden. Die Abzweigungsleitung zu dem Kollektor liegt vorteilhaft hinter dem Schalter la für den Elektromotor, so daß gleichzeitig mit dem Elektromotor auch der Frequenzmesser ein- und ausgeschaltet wird.One embodiment of the new facility is at the same time as theirs Circuit arrangement in the figure, in the top view of the motor breaker shown schematically. The circuit breaker a is in the manner known per se driven by the electric motor b, on whose axis now according to the invention of Collector c is attached. The number of collector lamellas d is equal to the number the one allotted to one revolution of the interrupter, by the interrupter itself caused current interruptions, so generally equal to the number of existing contact pieces. of the interrupter. The ones dragging on the collector Brushes e with the interposition of the frequency meter f with the (direct current) Source, such as the network g, connected. The branch line to the collector is located advantageous behind the switch la for the electric motor, so that at the same time with The frequency meter is switched on and off along with the electric motor.
Es ist so ermöglicht, die Unterbrechungsfrequenz an dem Frequenzmesser f abzulesen und beispielsweise mittels des für den Elektromotor dienenden regelbaren Widerstandes i einzustellen.It is thus possible to determine the interruption frequency on the frequency meter f can be read off and can be regulated, for example, by means of the one used for the electric motor Set resistance i.
In manchen Fällen kann es sich auch empfehlen, den Kollektor c und den Frequenzmesser f nicht an dieselbe Stromquelle wie den Unterbrecher anzuschließen, sondern durch eine besondere Stromquelle zu speisen.In some cases it can also be advisable to use collector c and not to connect the frequency meter f to the same power source as the breaker, but to be fed by a special power source.
