Transformer coil short-circuit mechanical force test system and test method thereof

The invention belongs to the technical field of transmission equipment, and relates to a transformer coil short-circuit mechanical force test system and a test method thereof, especially a method for calculating and testing the insulation compression stress of flat wires, combined lines, common transposed conductors and self-adhesive transposed conductors of different turn insulation thickness of transformers. According to the test system, a beam is mounted and vertically fixed on stand columns of a base; beam lifting hydraulic cylinders are mounted on the two sides of the base; the top ends of beam lifting piston rods in the beam lifting hydraulic cylinders are connected to the bottom of the beam; a workbench is mounted on the stand columns, and the workbench is disposed below the beam; a working hydraulic cylinder is mounted on the workbench, and a lower pressing plate is mounted on the top end of a working hydraulic piston rod in the working hydraulic cylinder; and an upper pressing plate corresponding to
