Description
ersten geradzahligen Stufenkontakt 2 bleibt hingegen frei, da zwischen diesen Stufenkontakten eine erhöhte Spannungsbeanspruchung vorliegt Der andere Teilring 51 liegt in der Ebene Vl und reicht vom ersten ungeradzahligen Stufenkontakt 1 bis zum letzten ungeradzahligen Stufenkontakt 17. Auch dieser Teilring 51 ist zusammen mit diesen Stufenkontakten 1, 3, ..., 17 an den entsprechenden Isolierstäben befestigt Der Bereich zwischen dem letzten und dem ersten ungeradzahligen Stufenkontakt 17 bzw. 1 bleibt hingegen wieder frei, da auch hier eine erhöhte Spannungsbeanspruchung vorliegt Wie aus den Figuren ersichtlich, überschneiden sich die beiden Teilringe 51 und 52, so daß mit ihnen insgesamt die Wirkung eines geschlossenen Stützringes erzielt wird. So sind beide Teilringe 51 und 52 gleichzeitig an den Isolierstäben der Stufenkontakte 1,3,5,7 und 13, 15, 17 befestigt Einerseits ist dann nur der obere Teilring 51 an den beiden Isolierstäben der Stufenkontakte 9 und 11 befestigt, die ja in dem von dem unteren Teilring 52 freigelassenen Bereich liegen, und andererseits ist nur der unteren Teilring 52 an dem Isolierstab des Stufenkontaktes 8 befestigt der seinerseits in dem von dem oberen Teilring 51 freigelassenen Bereich angeordnet istfirst even-numbered step contact 2 remains free, however, since between these step contacts an increased The other partial ring 51 lies in the plane Vl and extends from the first odd-numbered one Step contact 1 to the last odd-numbered step contact 17. This partial ring 51 is also together with these step contacts 1, 3, ..., 17 attached to the corresponding insulating rods The area between the last and the first odd-numbered step contact 17 or 1, however, remains free again, there Here, too, there is an increased stress load. As can be seen from the figures, overlap the two partial rings 51 and 52, so that with them overall the effect of a closed support ring is achieved. So both partial rings 51 and 52 are at the same time on the insulating rods of the step contacts 1,3,5,7 and 13, 15, 17 attached. On the one hand, only the upper partial ring 51 is then attached to the two insulating rods of the step contacts 9 and 11 attached, yes in that of the lower one Part of the ring 52 are exposed area, and on the other hand, only the lower part of ring 52 is on the insulating rod of the step contact 8, which in turn is arranged in the area left free by the upper partial ring 51 is

Because depending on the level in which such a step contact and the insulating rod of the first lower support ring is attached, at least one step contact with a number of wheels and the insulating rod of the penultimate one of these critical points would be bridged by the support ring over-wheel step contact with respect to all the others It must be assumed here that the distances between the insulating rods are enlarged. the even-numbered or odd-numbered step contacts would have to be arranged opposite the level of the odd-numbered level, since it is rotated by about 180 ° with the numbered step contacts. 30 individual insulating rods would have to be attached. Invented odd-numbered step contact-bearing insulation, this deficiency is avoided, since two lierstäbchen et * a opposite to the insulating rod of the last open partial rings, which are in their effect to an even-numbered step ^ ontak ^ s, and complement closed support ring, are used, further between the insulating rod of the first odd-numbered as a result of the twisting of the even-numbered and the innumerable step contacts and * there are no odd even-numbered contact levels, these partial-numbered step contacts are rotated against each other by just one straight ring, so that the exposed number of step contacts per phase carrying insulation - Area of one partial ring of the one level is about the rod and between the insulating rod of the last straight-free area of the partial ring of the other level contact and the insulating rod of the ne is opposite stress critical parts as pure oil stretch an odd numbered step contact per phase between the respective step contacts bearing insulating rod is arranged, after which hold, and nevertheless the effect of a closed main patent (P 27 49 852.8), thereby discarded support ring can be achieved,
