PERFECCIONAMIENTOS EN UN DEVANADO DE BARRAS CON ELEMENTOS DE CONDUCTOR RETORCIDOS ESPECIALMENTE PARA UNA MAQUINA ELEC- TRICA CON UNA TENSION NOMINAL SUPERIOR A 3,3KV

摘要

1. Barwinding comprising twisted conductor elements, for an electric machine with rated voltages of over 3.3 kVolt, uneven places on the narrow sides of the group of conductors being filled and the group of conductors being provided with inner corona shielding which has a maximum thickness of 0.15 mm and which is locally coupled to the conductor elements of the group of conductors by means of discharge channels forming when a voltage is applied which is excessive with respect to the rated voltage, characterized in that the inner corona shielding is constructed as inner corona shielding strips (6) which are applied only to the narrow side of the group of conductors and which are interrupted in the longitudinal direction of the bar.
