The present invention relates to a no-load tap reversing machine for an extra-high voltage transformer which comprises: a driving part which uni-directionally transmits driving force while normally and reversely rotates; a driving transmission part which is coupled to the driving part and bi-directionally transmits the driving force from both sides of the driving part; a transmission shaft unit which is respectively connected to the driving transmission part at both sides of the driving part and normally and reversely rotates at the same time in different direction; and a multi-points connecting module which is equipped with rotary contact which can rotate clockwise and counterclockwise at the same time while being interlocked with the rotation of the transmission shaft unit to each of multiple fixed contacts installed to a supporting plate disposed in multiples along the direction of forming the transmission shaft unit, therefore the no-load tap reversing machine for an extra-high voltage transformer can easily move electrical connecting tap points with a small resistance and moreover, can move further more electrical connecting tap points at the same time. |
