Claims (2)

1. Статор высоковольтной электрической машины, содержащий сердечник магнитопровода, в пазах которого расположены секции обмотки, состоящие из проводников, покрытых корпусной изоляцией, подвергающейся пропитке, поверх которой нанесено полупроводящее покрытие, причем обмотки зафиксированы в пазу клином, отличающийся тем, что полупроводящее покрытие выполнено состоящим из двух частей: обертки и накладки, при этом обертка выполнена из материала, который имеет низкий коэффициент трения к стали сердечника, не проницаем для пропиточного состава и обладает антиадгезионными свойствами, обертка охватывает удаленную от расточки грань и боковые грани секции обмотки; а накладка выполнена из материала, проницаемого для пропиточного состава, и размещена на грани секции обмотки, обращенной к расточке, таким образом, что ее наружные края заходят за внутренние края обертки; поверх накладки установлена прокладка, имеющая размер в тангенциальном направлении меньше, чем ширина паза секции обмотки, а между прокладкой и клином установлена дополнительная прокладка, выполненная из антиадгезионного материала.1. The stator of a high-voltage electric machine, containing the core of the magnetic circuit, in the grooves of which are located winding sections, consisting of conductors coated with body insulation, subjected to impregnation, on top of which a semi-conductive coating is applied, and the windings are fixed in the groove with a wedge, characterized in that the semi-conductive coating is made consisting of two parts: wrappers and pads, while the wrapper is made of a material that has a low coefficient of friction against core steel, not permeable to impregnating co Av and possesses anti-adhesion properties, the wrapper covers the bore remote from the face and side faces of the winding section; and the patch is made of a material permeable to the impregnating composition, and is placed on the edge of the winding section facing the bore, so that its outer edges extend beyond the inner edges of the wrapper; a gasket is installed on top of the lining, having a tangential dimension smaller than the width of the groove of the winding section, and an additional gasket made of release material is installed between the lining and the wedge. 2. Статор по п.1, отличающийся тем, что паз магнитопровода выполнен с расширением в сторону расточки статора.2. The stator according to claim 1, characterized in that the groove of the magnetic circuit is made with an extension towards the stator bore.
