The invention discloses an active protection system and method for overhead transmission line crossing construction, and belongs to the technical field of overhead transmission line crossing construction. The overhead transmission line crossing construction active protection system comprises active protection mechanisms installed on adjacent iron towers, the outer sides of the adjacent iron towers are provided with tension pay-off machines used for releasing constant tension of wires and traction machines used for pulling traction ropes, and the movable ends of the traction ropes and the movable ends of the wires movably penetrate through the active protection mechanisms and are connected through connectors; the active protection mechanism comprises a mounting seat mounted on the iron tower, and through the arrangement of the active protection mechanism, the occurrence of a pull-off fault at the connector is avoided, the situation that a spanned object is damaged due to impact on the spanned object caused by
