The invention discloses an alternating-current voltage-withstand high-voltage test device used for an insulation rope and capable of automatically winding the rope. Each of two brackets comprises insulation rods; the brackets are arranged at two ends of an angle iron framework respectively; a rotary column is arranged between the brackets; the rotary column is connected with the brackets through bearings; insulation plates are arranged at two ends and in the middle of the rotary column; the rotary column penetrates through the center of each insulation plate; the insulation plate is square; solid copper rods are arranged on four corners of the insulation plate; both a motor and a speed reducer are arranged in the angle iron framework; the motor, the speed reducer and the rotary column are connected through a conveying belt; the rotary column is driven by the motor to rotate; a base is arranged on one side of the angle iron framework; a travel column is arranged on the base and parallel to the rotary column; a wire arrangement device is arranged on the travel column and slides on the travel column. The alternating-current voltage-withstand high-voltage test device has the advantages that manpower and material resources are saved, an alternating-current voltage-withstand test of batches of insulation ropes is finished, and the working efficiency is improved.
