Winding equipment for transformer iron core

Abstract

The invention discloses winding equipment for a transformer iron core. The winding equipment comprises a winding base, tapping rods, a top plate, a bottom frame and a fixation support. The fixation support is arranged on the bottom frame; the fixation support is vertically fixed to the bottom frame; the tapping rods are arranged at two horizontal ends of the top plate; the tapping rods are vertically welded to the top plate; the winding base is arranged between the two tapping rods; the fixation support is movably mounted at the top end of the winding base; the fixation support is provided with an armature block and a bottom groove; the bottom groove is of a horizontal square structure; the bottom groove and the armature block are horizontally fixed; the armature block is located in the middle of one side face of the bottom groove; and the armature block of the bottom groove is movably clamped to the winding base. Steel sheets are placed in arc-shaped notches in the bottom groove in aone-to-one correspondence mode; through the design of the arc-shaped notches, the positions are more targeted, the phenomenon of horizontal slipping and toppling is not likely to happen, and alignmentcan be conducted; and the tightness of connection between the two is enhanced through the magnetic blocks between every two arc-shaped notches and through attraction of the soft magnetic materials and the magnetic fields of the magnetic blocks.

Description

technical field [0001] The invention relates to the field of transformers, in particular to winding equipment for transformer iron cores. Background technique [0002] Winding cores are commonly used in small and medium-sized transformers (below 1000kVA), transformers, magnetic amplifiers, and zero-sequence current transformers for leakage protectors. The material used for winding cores is ultra-thin cold-rolled silicon steel with high magnetic permeability. Soft tape materials such as sheet and permalloy. The thickness of the silicon steel sheet is 0.18-0.30mm; the thickness of the permalloy strip is 0.03-0.10mm. The winding iron core is suitable for small and medium-sized transformers, but in the winding process, the ultra-thin cold-rolled silicon steel sheet with high magnetic permeability, the material It is prone to horizontal deviation, inaccurate positioning, prone to position deviation, inaccurate alignment of steel sheets, deviation in winding, and easy burning of ...
