Abstract

The invention discloses a high voltage wire leading method for a stereoscopic wound core open ventilated dry-type transformer, which comprises the steps of fixing stereoscopic wound cores arranged in a triangular shape between an upper clamp and a lower clamp, winding A, B and C three phase coils on the stereoscopic wound cores and arranging a high voltage wire leading bracket on the upper clamp, wherein the high voltage wire leading bracket is provided with connecting terminals which respectively correspond to the A, B and C three phase coils; and each phase coil is respectively provided with a wire inlet terminal and a wire outlet terminal. In the high voltage wire leading method, each of the three A, B, and C phase coils is provided with two wire outlet terminals and the numbers of turns of the three phase coils are still equal, so that under the condition of not changing the numbers of the turns of the coils, the added wire outlet terminals make leading more conveniently and the lead structure simpler.
