A transformer spiral winding cable arrangement

Abstract

The invention discloses a spiral winding arranging device of a transformer. Equal internal threading grooves symmetrically distributed relative to the central vertical axis and four installation long-strip holes for a wire baffle are formed in the two ends of a threading plate, wherein the number of the equal internal threading grooves is multiples of four. The long-strip holes are located in the upper edge and the lower edge of the threading plate, and four installation holes for an adjusting plate are formed in the upper ends and the lower ends of the left and right middle positions of the threading plate. An adjusting plate is fixed to a support and provided with two vertical twos of fixing holes. The wire baffle is fixed to the threading plate in a left-right position adjustable mode. The lower end of the support is fixed to a base, or a hanging plate is fixed to the upper end of the support. By means of the spiral winding arranging device, a wire can be neatly wound in parallel, the tension force of the wire wound in parallel is consistent, the probability of burning of the transformer is reduced, and the safety performance of the transformer is improved; besides, both a single-spiral structure and a dual-spiral structure can be used, and thus university is high.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing, and relates to a transformer spiral winding cable puller. Background technique [0002] At present, the low-voltage windings of medium and large-capacity transformers mostly adopt spiral type due to the large current winding structure, and the number of winding coils is an integer multiple of 4, and the number does not exceed 48 at most. The spiral coil has a simple structure and a wide range of applications. However, during the winding process, due to the large number of windings in parallel, the force on individual coils is uneven. Bending or buckling instability, this kind of deformation can easily lead to the burning of the transformer. Once the transformer is burned, it will not only have a huge impact on the power supply network, but also endanger the safety of personal property and cause huge losses to the power supply company and users.
