Description
Technical Field
The invention relates to the technical field of high ends of extra-high voltage equipment, in particular to a six-direction adjustable twisting transposition device for transposed conductors.
Background
The winding is a core component of the reactor, and is directly related to the quality of core parameters of the reactor and the stability and safety of operation, and is used for a high-voltage and high-capacity reactor matched with ultra-high voltage and ultra-high voltage transmission, as the application requirements are higher and higher, a round single-wire stranded transposed conductor is gradually adopted as the winding, so that the strength of the winding can be remarkably improved, the compactness of the structure is improved, the eddy current loss is reduced, and the cost performance of a product is optimized.
The core part of the transposed conductor manufacturing equipment is a stranded transposition device. In the strand transposition process of the transposed conductor, a plurality of single wires are required to be gradually changed from circular ring arrangement to flat ring arrangement until being bundled together, and finally the single wires are stranded and transposed according to the same pitch, the same stranded direction and the same angle to form a rectangular transposition strand with double-layer arrangement. The main function of the twisting transposition device is to ensure the uniformity and the accuracy of the transposition wire structure, wherein the uniformity is represented by the deformation consistency and the pitch length consistency of each single wire, and the accuracy is represented by whether the single wire arrangement sequence is changed. The transposed conductor belongs to a customized product, the number and specification of monofilaments and the distribution range of the structural dimension (such as the width-to-thickness ratio) of the conductor are larger, and the technical requirements of the transposed conductors with different specifications on the transposition device are also different to a certain extent. For example, the thicker the filament gauge, the higher the stiffness requirement for the displacement device; the larger the width-to-thickness ratio of the wire is, the higher the probability of occurrence of the jumper wire is, the gap size of the transposition channel needs to be reduced to reduce the jumper wire probability, but reducing the gap size of the transposition channel can increase transposition resistance, so that abnormal extrusion deformation of a single wire and even wire breakage accidents are caused, and the flexible characteristic of the transposition channel can well balance the contradiction between the two; the wires with different specifications have larger difference in pitch length, size thickness and the like, and the transposition device is required to have a certain displacement adjustment space in the up, down, front, back, left and right directions, so that the requirements of the wires with different specifications on the differentiation in the doubling angle, stranded wire pitch and the like are met.
The existing transposition device is basically a fixing device, the rigidity of the device is excessive, but the flexibility is insufficient, and few cases have single-direction adjustment, such as adjustment of the advance and retreat of a die assembly to adapt to the requirements of different doubling angles, but the technological requirements of uniform transposition and accurate transposition of a transposition wire cannot be met.
