Description

Einrichtung zum Anlassen von Einphasen-Induktionsmotoren mit Hilfswicklung und Drosselspule Es ist bekannt, Einphasen - Induktionsmotoren mittels Hilfswicklung und einer dieser Wicklung vorgeschalteten Drosselspule anzulassen.Device for starting single-phase induction motors with auxiliary winding and choke coil It is known to use single-phase induction motors by means of auxiliary winding and to start a choke coil upstream of this winding.

In Abb. i ist a die Arbeitswicklung des Primärteils des Einphasen-Induktionsmotors, lt die um 9o elektrische Grade verschobene Hilfswicklung, d eine Drosselspule, s die) Sekundärwicklung gnd Y :dier Anlaßwiderstand.In Fig. IA, the working winding of the primary part of the single-phase induction motor, according to the shifted 9o electrical degrees auxiliary winding, i.e., a choke coil, s the) secondary winding gnd Y: commanding starting resistor.

Bei hohen Netzspannungen macht die Isolierung der Wicklung h Schwierigkeiten. Man verwendet nämlich für die Wicklung h etwa 1/3 ioder weniger ;der gesamten Nuten des Primärteils, macht dann aber zur Erzielung eines besseren Anlaufs die Zahl der Leiber je Nut für die Hilfswicklung wesentlich größer als für die Hauptwicklung.At high mains voltages, the insulation of the winding h causes difficulties. About 1/3 i or less of the total slots of the primary part are used for the winding h, but then, in order to achieve a better start-up, the number of bodies per slot for the auxiliary winding is significantly greater than for the main winding.

Erfindungsgemäß soll nun die Hilfswicklung h durch die Anlaßdrosselspule d vor den beim Einschalten auftretenden Wanderwellen geschützt werden. Hierzu wird die Anlaßdrossel in zwei Teile unterteilt, die vor und hinter die Wicklung h gelegt werden (s. Abb. z).According to the invention, the auxiliary winding h is now to be protected from the traveling waves occurring when switching on by the starting choke coil d. For this purpose, the starting choke is divided into two parts, which are placed in front of and behind the winding h (see Fig. Z).

Zum Unterschied der Anordnung nach Abb. i ist in Abb. z die Anlaßdrossel in zwei Teile dl und d2 unterteilt, .die seinen gemeinsamen Eisenkern besitzen können.In contrast to the arrangement according to Fig. I, Fig. Z shows the starter throttle divided into two parts dl and d2, .which can have its common iron core.
