Distributed tapped transformer winding and method of winding same

Claim 1

A distributed tapped transformer winding comprising a plurality of tap sections each comprising winding turns distributed along a substantial part of the axial length of the tapped winding, at least one of said tap sections having one more winding turn than other tap sections, each tap section being wound from a corresponding conductor, the plurality of conductors corresponding to the plurality of tap sections being arranged in a winding bundle, said winding bundle being wound from one end of said tapped winding toward the opposite end of said tapped winding to form a single layer winding in which the conductor turns within the winding bundle are arranged in accordance with a predetermined sequence which differs from the sequence in the distributed tapped winding of the tap sections to which the respective conductors correspond, all of the conductor turns of the bundle starting at substantially the same angular position at said one end and progressing toward an opposite end at which the said at least one conductor corresponding to said at least one of said tap sections is wound through one more winding turn than the remaining conductors, the at least one conductor corresponding to the at least one tap section have one more winding turn being positioned at the ''''lagging'''' position in the bundle relative to said direction of winding, the remaining conductors corresponding to the remaining tap sections being positioned at the ''''leading'''' end of the bundle, whereby the ends of said remaining conductors may be brought out at said opposite end for connection to a terminal board or the like without crossing over the said at least one conductor corresponding to said at least one tap section having one more winding turn.

Claim 7

The method of winding a single layer distributed tapped transformer winding of thE type having a plurality of tap sections and in which at least one of said tap sections has n+1 winding turns while the remainder of said tap sections each respectively have n winding turns, comprising the steps of: a. arranging a plurality of electrical conductors in a winding bundle, with each of said conductors corresponding to and forming when wound a particular one of said tap sections; said conductors being positioned in a sequence in said bundle which differs from the sequence in the distributed tapped winding of the tap sections to which the respective conductors correspond; b. positioning the at least one of said conductors corresponding to the at least one of said tap sections having n+1 winding turns at the most lagging part of the winding bundle relative to the direction of winding; c. positioning the conductors corresponding to the remainder of said tap sections which have n winding turns at the leading part of the winding bundle relative to the direction of winding; d. winding said bundle helically from one end of said distributed winding at which the ends of said plurality of tap sections all start at substantially the same angular position toward an opposite end at which the said at least one conductor corresponding to the said at least one tap section having n+1 winding turns is wound through one more winding turn than the said remaining conductors; e. at the end of n winding turns from said one end ''''peeling'''' off from said winding bundle for connection to the terminal board of the transformer the conductors corresponding to the remainder of said tap sections which have n winding turns; f. at the end of n winding turns from said one end, continue to wind through one additional winding turn the said at least one conductor corresponding to the said at least one tap section having n+1 winding turns.

Claim 8

The method of winding a single layer distributed tapped transformer winding of thE type having a plurality of tap sections and in which at least one of said tap sections has n+1 winding turns while the remainder of said tap sections each respectively have n winding turns, comprising the steps of: a. arranging a plurality of electrical conductors in a winding bundle, with each of said conductors corresponding to and forming when wound a particular one of said tap sections; said conductors being positioned in a sequence in said bundle which differs from the sequence in the distributed tapped winding of the tap sections to which the respective conductors correspond; b. positioning the at least one of said conductors corresponding to the at least one of said tap sections having n+1 winding turns at the most lagging part of the winding bundle relative to the direction of winding; c. positioning the conductors corresponding to the remainder of said tap sections which have n winding turns at the leading part of the winding bundle relative to the direction of winding; d. winding said bundle helically from one end of said distributed winding at which the ends of said plurality of tap sections all start at substantially the same angular position toward an opposite end at which the said at least one conductor corresponding to the said at least one tap section having n+1 winding turns is wound through one more winding turn than the said remaining conductors; e. at the end of n winding turns from said one end ''''peeling'''' off from said winding bundle for connection to the terminal board of the transformer the conductors corresponding to the remainder of said tap sections which have n winding turns; f. at the end of n winding turns from said one end, continue to wind through one additional winding turn the said at least one conductor corresponding to the said at least one tap section having n+1 winding turns.
