Background
The flexible-direct transformer coil winding is close to the upper and lower outlet ends, the impact gradient is large, and a shielding wire is often required to be added at the position to enable the impact distribution of the end part of the winding to be uniform. The winding of the flexible-direct transformer coil in the prior art mostly adopts a structure of welding shielding wires at two adjacent ends, the routing of the shielding wires in the structure has great limitation, the shielding wires need to be welded at two adjacent sections of windings at a great distance in the radial direction, the operation is complex, and the radial tolerance of the windings is easily caused.
Disclosure of Invention
The invention aims to provide a winding method of a span-type inserted shielding wire continuous winding of a flexible-direct transformer, which adopts span-type welding of shielding wires, welds the shielding wires together at adjacent and close positions at intervals of a wire cake, enhances the shielding effect at the head of a coil winding, has simple operation and enhances the operation safety of the flexible-direct transformer
The technical scheme of the invention is as follows:
a winding method for a span type inserted shielding wire continuous winding of a flexible-direct transformer is characterized in that a span type inserted shielding wire is adopted at the wire cakes close to the upper and lower head ends of a coil, and the shielding wires are welded together at intervals of one wire cake.
Compared with the conventional welding mode, the welding method is simple to operate, easy to control the radial tolerance of the winding, more effective in optimizing the winding structure and improving the running reliability of the flexible-direct-current transformer. Because the upper and lower outlet ends of the coil winding of the flexible-direct transformer have larger impact gradient, the shielding wires are welded together in a span-type manner by adopting shielding wire welding and separated by a wire cake. The shielding mode enhances the shielding effect of the coil winding at the outlet, so that the impact distribution of the end part of the winding is uniform, the operation is simple, and the running safety of the flexible-direct transformer is enhanced.
The invention has the beneficial effects that: the shielded wire is welded in a small span, so that the space is saved, the operation is simple, the tolerance is easy to control, and the installation is convenient. The shielding of the upper and lower outlet parts of the coil winding can be more effectively optimized, the impact gradient of the coil is reduced, and the running reliability of the flexible-direct transformer is improved.
