Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transposed conductor detection, in particular to a transposed conductor jumper detection device. Background Art
[0002] Transposition conductor is a special conductor structure, which is mainly used in the winding design of large power transformers. It consists of multiple enameled flat copper wires arranged in two rows, and the transposition is carried out in sequence and evenly according to the double spiral winding transposition method. There are two specific reasons for the jump of enameled flat copper wires: first, the wire jumps out from the transposition position and overlaps on the top of the two rows of enameled flat copper wires, or the transposition is two enameled flat copper wires at a time or one enameled flat copper wire is missed. In this case, the thickness of the transposition conductor exceeds the normal size range; second, when the enameled flat copper wire is transposed and deformed, the enameled flat copper wire is overturned, causing the enameled flat copper wire to be sandwiched between the two rows of wires or jump out of the two rows of wires. In this case, the width of the transposition conductor exceeds the normal size range. Since the transposition conductor with jump is not easy to detect during the production process, it is easy to cause serious quality accidents.
[0003] Most of the currently used transposed conductor mechanisms can generally only perform jumper detection on transposed conductors of a single size. When transposed conductors of different sizes are used, multiple detection mechanisms need to be equipped, which makes the versatility of the detection mechanisms poor and increases the cost of use.

[0021] like Figure 4As shown, the top of the mounting frame 12 is rotatably connected with an adjusting screw rod 21, one end of the adjusting screw rod 21 passes through the top of the detection box 11 and meshes with the inside of the detection box 11, and the top of the detection box 11 and near the two sides are slidably connected with positioning columns 20, and the bottom ends of the two positioning columns 20 are fixedly connected to the top of the mounting frame 12.

[0022] like Figure 4 As shown, positioning grooves 22 are provided on both side walls of the detection frame 13 , and both ends of the fixed frame 16 are slidably connected to the inside of the two positioning grooves 22 , so as to position the fixed frame 16 and prevent it from being skewed.
