Wrench special for wire transposition

Abstract

The invention discloses a wrench special for wire transposition. The wrench is used in wire transposition winding of transformer windings and comprises a handle, wherein two groups of wire transposition locking devices used in a matching mode are fixed on the same side of the handle, each wire transposition locking device comprises a wire clamping board fixed on the surface of the handle, the thickness of the wire clamping board is no less than that of the wire, a wire locking board is arranged on the outer side of the wire clamping board, and the area of the wire clamping board is less than that of the wire locking board. Wires are clamped and fixed by the two wire clamping boards and the two wire locking boards when the wrench is used for performing wire transposition, transposition can be performed conveniently, the time for 'S'-shaped bending transposition of the wires of the windings can be shortened, wire abrasion can be reduced, diameter clearance among the wires is reduced, manufacturing can be finished in one step, manufacturing efficiency is improved by three to four times, technological requirements of production can be met, and quality of the transformer windings can be ensured.

Description

technical field [0001] The invention relates to a transformer manufacturing auxiliary tool, in particular to a special wrench for transposition of transformer winding wires. Background technique [0002] At present, in the production field of transformers, the transformer winding wires are wound and transposed by simple manual wire "S" bending. Using the above method for wire transposition mainly has the following disadvantages: First, the time for wire winding and transposition is too long, Seriously reduces the production efficiency of the transformer winding; second, after the wires are transposed and wound, the gap between the wires is large, so the insulation part is easily damaged, which seriously affects the safety of the transformer, and the quality of the transformer product cannot be guaranteed. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special wrench for wire transposition with simple struct...
