Title:
TRANSFORMER SILICON STEEL SHEET STACKING AND WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/196676
Kind Code:
A1
Abstract:
A transformer silicon steel sheet stacking and welding method, comprising the following steps: step 1, material preparation; 2, E sheet stacking; 3, E sheet assembly: loading stacked E-shaped silicon steel sheets into a middle hole of a transformer framework, wherein the loading direction cannot be offset or skewed so as to prevent the silicon steel sheets from wire breakage due to damage to enameled wires for winding a coil in the framework; step 4, I sheet stacking and assembly: stacking I-shaped silicon steel sheets according to the stacking thickness of the E-shaped silicon steel sheets, and then placing the stacked I-shaped silicon steel sheets on the E-shaped silicon steel sheets; step 5, silicon steel sheet welding; and step 6, weld inspection. The transformer silicon steel sheet stacking and welding method has the following beneficial effects: the preparation process therefor is reasonable in design, the stacking and welding production efficiency of silicon steel sheet products is high, and the protection process is reasonably designed, so that the product rejection rate is low, the raw material production cost input is reduced, and the manufactured products are excellent and stable in quality.
