Description

Technical Field

[0001] The utility model relates to the technical field of transposed conductor detection, in particular to a transposed conductor shape dimension detection device. Background Art

[0002] As an important winding material in power equipment such as power transformers and reactors, transposed conductors have broad application prospects. Through a specific transposition weaving process, transposed conductors closely arrange multiple enameled flat wires to form a winding with a compact structure and excellent electrical performance. This winding material can not only effectively reduce the size of the equipment and improve space utilization, but also significantly reduce eddy current loss and circulating current loss in the winding, improve the operating efficiency of the equipment, and is widely used in high-end power equipment such as high-voltage and large-capacity power transformers. However, the electrical performance and operating stability of the transposed conductor are often affected by its dimensional accuracy. Therefore, during the manufacturing and use process, it is very important to detect the external dimensions of the transposed conductor.

[0003] The surface of the transposed conductor is not flat due to the transposition pitch, and there are gaps between the transposed wire cores, which brings great difficulties to the measurement of the conductor's external dimensions. The measurement results will be affected by the measurement personnel and equipment. Due to the uneven measurement levels of different personnel or the different accuracy of the measurement equipment, the measurement results of the transposed conductor's external dimensions will also have large deviations. Later, with the development and maturity of measurement technology, the measurement force was unified. However, the measurement must be carried out after the pressure is adjusted using special equipment with air pressure. The preparation time for the measurement is long, and the measuring chuck is short, which cannot cover the two transposition pitches of the transposed conductor, and cannot detect the maximum external dimensions of the transposed conductor, which makes it difficult to meet the use requirements of the transposed conductor in the transformer.
