The present invention relates to a method for repairing a break strand of an overhead ground wire, belonging to the field of overhead ground wire repairing technologies. The method includes the steps that an operator carries a passing rope and climbs to the top of a tower and unties a wire clip of the overhead ground wire, disassembles the overhead ground wire, descends and places the overhead ground wire on a cross arm below the overhead ground wire; the operator on the tower lands the overhead ground wire from the cross arm to a wire at the same side, and firmly suspends the overhead ground wire with a connecting fitting connected on the cross arm; and the operator on the tower and an operator on a wire cooperate to suspend a hanging ladder pulley on the wire, then the operator on the wire rides the hanging ladder pulley and cooperates with a ground controller so as to slide to the break strand of the overhead ground wire to repair the break strand, meanwhile, and a person on the ground controls the overhead ground wire and the wire by using a rope, so as to keep a proper operation distance between the overhead ground wire and the wire. The method for repairing the break strand of the overhead ground wire is applicable to any complex external environment, and can shorten repair time, reduce laborers, and lower labor intensity.
