Description
Bei Flachleiterwicklungen für elektrische Hochspannungsmaschinen wurde vorgeschlagen, die Ober- und Unterleiter der Wicklung in der Nut, also die am Nutengrund und an der Ständerbohrung lagernden Leiter, sehr stark, z. B. halbkreisförmig, abzurunden, um dadurch die Verteilung des elektrischen Feldes in der Nut zu viergleichmäßigen und Glimmentladungen zu begegnen. Der Spulenquerschnitt erhält dann den in Abb. 1 dargestellten Aufbau mit dem stark abgerundeten Rückenleiter 1, beispielsweise drei Flachleitem 2, 3 und 4, und den wie 1 stark abgerundeten Bohrungsstab 5.In the case of flat conductor windings for electrical high-voltage machines, it was proposed that the upper and lower conductors of the winding in the slot, i.e. the one at the base of the slot and on the stator bore superimposed conductor, very strong, z. B. semicircular, round to thereby the distribution of the electric field in the groove to four uniform and To counter corona discharges. The coil cross-section then has that shown in Fig. 1 Structure with the strongly rounded back conductor 1, for example three flat conductors 2, 3 and 4, and the drill rod 5, which is strongly rounded like 1.
Nun ist es aber erforderlich, eine Kompensation der vom Nutenquerfeld in verschiedenen Nutentiefen induzierten elektromotorischen Kräfte durch den üblichen Lagenwechsel der Leiter vorzunehmen. Diese an sich bekannte Vertauschung kann man zufolge des halbkreisförmigen Querschnittes nicht ohne weiteres durch eine Verschränkung der so profilierten Ober- und Unterleiter 1 und 5 mit den flachen Leitern 2, 3 und 4 in der Nut bewerkstelligen.But it is now necessary to compensate for the cross-field of the groove in different Groove depths induced electromotive forces through the usual change of position the ladder make. This exchange, known per se, can be made due to the semicircular cross-section not simply by entangling the top and bottom ladder 1 so profiled and accomplish 5 with the flat conductors 2, 3 and 4 in the groove.
Um die abgerundeten Ober- und Unterleiter ι und 5 nichtsdestoweniger in den Lagenwechsel einzubeziehen und sie als vollwertige Wicklungsteile auszunutzen, sind sie erfindungsgemäß außerhalb der Nut, wie Abb. 2 veranschaulicht, als abgeflachte Leiter 1' bzw. 5' über den Wickelkopf weitergeführt und dort bei c nach dem bekannten Prinzip der cyclischen Vertauschung der Teilleiter mit den übrigen Flachleitern 2, 3 und 4 verschränkt, so daß ein Lagenwechsel aller Leiter beim Übergang von einer Nut zur nächsten stattfindet. Es ist zweckmäßig, die Übergangsstellen α und b von der halbrunden zur flachen Querschnittsform erst in einem angemessenen Abstand vom wirksamen Eisen anzuordnen und allmählich verlaufend zu gestalten, damit im Bereich des Eisens auch außerhalb der Nut eine Glättung des elektrischen Feldes erreicht wird.In order to nonetheless include the rounded upper and lower conductors ι and 5 in the change of position and to use them as fully-fledged winding parts, according to the invention they are continued outside the groove, as illustrated in Fig. 2, as flattened conductors 1 'and 5' over the winding head and there at c according to the known principle of cyclic interchanging of the sub-conductors with the remaining flat conductors 2, 3 and 4, so that a change in position of all conductors takes place at the transition from one slot to the next. It is advisable to arrange the transition points α and b from the semicircular to the flat cross-sectional shape at an appropriate distance from the effective iron and to make them gradual so that the electric field is smoothed outside the groove in the area of the iron.
