Device for attachment of coil ends in generator stator high-voltage winding
First Claim
1. A device for attachment of generator stator high-voltage winding coil ends, comprising insulation spacers disposed on external surfaces of the coil end bars, extra spacers disposed between the coil end bars, characterized in that it also comprises a case (1) made of two coaxial truncated cone members (2 and 3) and a part of a torus member (4) made integral therewith and provided with a joint (5) with a sealing (6), said case (1) accommodating insulation spacers (13), extra spacers (18), spring stops (15) secured inside the case (1) to the side surface thereof and located opposite each insulation spacer (13), and platens (14), each said platen (14) being disposed between two insulation spacers (13) and attached to one of them, the insulation spacers (13) being disposed between the winding coil end bars (16) and spring stops (15), each surface part of the insulation spacers (13), platens (14) and spring stops (15) and an inner side surface of the case (1) being used as cooling passages.

Abstract
A device for attachment of coil ends in a generator stator high-voltage winding includes insulation spacers (13) disposed on external surfaces of the coil end bars (16), auxiliary spacers disposed between coil end bars (16), a case (1), spring stops (15) anchored inside the case (1), and planks (14). The case (1) is made of two coaxial truncated-cone members (2 and 3) and a part of a torus member (4) made integral therewith and incorporating a joint (5) with a seal (6). Each plank (14) is arranged between two insulation spacers (13), and the insulation spacers (13) are arranged between the coil end bars (16) and the spring stops (15). The insulation spacers (13), the planks (14), the spring (15) and a side surface of the case (1) form cooling passages.
