(II) background of the invention
In an oil-immersed power transformer with a low-voltage winding of more than 35kV, a large-sized lead or a transposed conductor is generally adopted due to large current, in the initial calculation design, in order to meet the short-circuit resistance of the winding, more grades are often designed to meet the calculation margin of the winding inclination force, the spacing between winding grades is smaller due to the design of more grades, and for the lead with higher yield strength, especially for the transposed conductor, the existing equipment can only enable the lead to be bent and changed by a smaller degree due to higher mechanical strength of the lead. The transverse space required by the wire for transposition in the adjacent cake is limited, so that the wire transposition needs to be carried out in two grades, namely the trans-grade transposition, the trans-grade transposition needs to cross the cushion block, the upper part and the lower part of the wire need to be added with the transposition ox horn to fill the gap in the height direction and the radial direction, the filling rate of the coil is reduced, the product economy is reduced, when the filling ox horn cushion block is suitable for different wire gauges and coil diameters, the size drawn by a drawing is easy to have larger deviation with the actually required size, the condition of material waste is easy to cause due to mismatching of the ox horn cushion block, and the high price of the filling laminated paper board further restricts the economy of a power transformer product.

(V) detailed description of the preferred embodiments
The attached drawing is an embodiment of the invention. This embodiment includes left operation arm 1 and right operation arm 2, and left operation arm 1 includes two left operation boards 3, welds left dead lever 4 between two left operation boards 3, and right operation arm 2 includes right operation board 5, welds right dead lever 6 respectively and revolves to twist screw 7 above the right operation board 5, and left operation board 3 tip is seted up notch 8, and the notch 8 card is gone into to twist and is twisted screw 7, revolves to twist and install on the screw 7 and twist nut 9. The bearing wheel 10 is sleeved on the left fixed rod 4. The bottom of the left operating plate 3 is provided with a left steel pipe 11. The bottom of the right operation plate 5 is provided with a right steel pipe 12.
By adopting the large-angle bending equipment for the winding wire of the transformer coil, the left fixing rod 4 penetrates through the bearing wheel 10 and is welded with the two left operating plates 3 at the opening positions of the two left operating plates 3, the two left operating plates 3 are kept parallel, and the tail part of the left operating plate is welded with the left steel pipe 11 for fixing and operating use, so that the left operating arm 1 is formed. In the left operation arm 1, the notch that the upper end of left operation board 3 was opened needs to be greater than the diameter of revolving screw 7, and the both sides width of the opening of left operation board 3 is great simultaneously to guarantee left operation board 3's intensity, the welding trompil position of fixed left dead lever 4 on the left operation board 3, and the centre-to-centre spacing with the notch 8 department that the upside was opened is suitable, and the width of bearing wheel 10 should not be too narrow. Welding a right fixing rod 6 on one side above a right operating plate 5, turning an external thread at one third of a turning screw 7 to one end of the turning screw 7, welding the end, which is not turned with the thread, of the turning screw 7 at the opening of the right operating plate 5, ensuring that the turning screw 7 is exposed out of the lower part of the right operating plate 5 at a proper distance, brazing during welding, reducing the size of a weld beading on the lower surface, preventing the weld beading on the upper surface, keeping a proper distance between the position of the right fixing rod 6 of the right operating plate 5 and the opening of the turning screw 7, welding a right steel pipe 12 at the tail part of the right operating plate 5, and fixing and operating the right operating arm 2 to form the right operating arm.
