Manufacturing method of balance transformer compensation coil

Abstract

The invention discloses a manufacturing method of a balance transformer compensation coil. The method comprises a process I, a process II, a process III, a process IV and a process V. In the process I, an upper half part of an inner coil, a lower half part of the inner coil, an upper half part of an outer coil and a lower half part of the outer coil are simultaneously wound into a whole body; in the process II, the upper half part and the lower half part of the inner coil complete sleeving work, and outgoing lines of the upper half part and the lower half part of the inner coil are in S-bend transition to a middle position of the outer coil; in the process III, the outgoing lines of the upper half part of the inner coil and the lower half part of the outer coil are welded and bound; in theprocess IV, the upper half portion of the outer coil and the lower half portion of the inner coil are welded and bound; and in the process V, integral sleeving of the upper half part of the inner coil, the lower half part of the inner coil, the upper half part of the outer coil and the lower half part of the outer coil is completed. According to the manufacturing method of the balance transformercompensation coil, under a condition that mechanical performance and electrical performance of a transformer product are guaranteed, barrier-free operation of all procedures is ensured.

Description

technical field [0001] The invention belongs to the technical field of balancing transformer compensation coil winding technology application, and in particular relates to a manufacturing method of a balance transformer compensation coil. Background technique [0002] The balance transformer compensation coil is composed of four coils, which are the upper half of the inner coil, the lower half of the inner coil, the upper half of the outer coil and the lower half of the outer coil; the manufacturing process is divided into two steps: winding process and packaging process . The specific operation is as follows: The first step is the coil winding process: respectively wind the upper half of the inner coil, the lower half of the inner coil, the upper half of the outer coil and the lower half of the outer coil, a total of 4 sets. Due to the small margin of the inner and outer coils, it is necessary to ensure that the dimensions of the inner coils and outer coils are the same, a...

AI Technical Summary

Problems solved by technology

[0003] The current production process has the following problems: the four coils are wound separately and then assembled, because the external dimensions of the inner and outer coils cannot be guaranteed to be the same, which makes it difficult to operate the inner and outer coils as a whole; Left and right, the lead wires are too close to each other, the space is narrow, it is difficult to weld the lead wires, and it is easy to damage the insulation parts of other parts during welding; and because the unilateral wrapping of the lead wires requires about 4mm, the wrapping thickness is thick and awl-shaped, resulting in It is difficult to operate the lead wire binding process
