Abstract
Methods for replacing a Wye-ring of a wind turbine generator preferably, but not necessarily, in-situ are described along with a combination of three arcuate Wye-ring sections that when assembled comprise a Wye-ring. The method after gaining access to the Wye-ring typically comprises: removing all or most of the damaged Wye-ring; installing the replacement sections typically by welding or brazing them in place; insulating the new ring; installing new blocking; and adhesively securing the new blocking in place.
Claims11
A method of replacing a Wye-ring of a generator with a replacement Wye-ring, the method comprising:
- providing the replacement Wye-ring comprising in combination
- (1) a first arcuate section having an effective radius comprised of one or more strips electrically conductive ribbon, the first arcuate section including first and second ends with the respective ends including radially outwardly extending first and second arms,
- (2) a second arcuate section, having the effective radius comprised of one or more strips electrically conductive ribbon, the second arcuate section including third and fourth ends with the respective ends including radially outwardly extending third and fourth arms, and
- (3) a third arcuate section having the effective radius comprised of one or more strips electrically conductive ribbon, the third arcuate section including fifth and sixth ends with the respective ends including radially outwardly extending fifth and sixth arms;
- dismantling the generator to gain access to the Wye ring,
- removing the annular ring of the Wye-ring while leaving most to substantially all of three radially extending cups in place,
- attaching each of the first, second, third, fourth, fifth and sixth arms to one of the three radially extending cups;
- and
- reassembling the generator.
A method of replacing a Wye-ring of a generator with a replacement Wye-ring, the method comprising:
- providing the replacement Wye-ring comprising in combination
- (1) a first arcuate section having an effective radius comprised of one or more strips electrically conductive ribbon, the first arcuate section including first and second ends with the respective ends including radially outwardly extending first and second arms,
- (2) a second arcuate section, having the effective radius comprised of one or more strips electrically conductive ribbon, the second arcuate section including third and fourth ends with the respective ends including radially outwardly extending third and fourth arms, and
- (3) a third arcuate section having the effective radius comprised of one or more strips electrically conductive ribbon, the third arcuate section including fifth and sixth ends with the respective ends including radially outwardly extending fifth and sixth arms,
- wherein the first, second, third, fourth, fifth and sixth arms each extend about 2.80″ and include an outward jog about half to three-quarters of the distance up the arm to form one half of a cup;
- dismantling the generator to gain access to the Wye ring;
- substantially removing the Wye-ring;
- both attaching each of the first, second, third, fourth, fifth and sixth arms to a coil of the generator and attaching adjacent arms of the first, second, third, fourth, fifth and sixth arms to form a Wye ring cups;
- and
- reassembling the generator.
