Transformer silicon steel sheet stacking and welding method

Abstract

The invention belongs to the technical field of transformer silicon steel sheet application, and particularly discloses a transformer silicon steel sheet stacking and welding method. The method comprises the steps 1, preparing materials; 2, stacking E-shaped sheets; 3, assembling the E-shaped sheets, specifically, putting the stacked E-shaped silicon steel sheets into a middle hole of a transformer framework, and paying attention to that the loading direction cannot deviate or incline so as to prevent the silicon steel sheets from damaging enameled wires for winding a coil in the framework andbreaking the wires; 4, stacking and assembling I-shaped sheets, stacking the I-shaped silicon steel sheets according to the stacking thickness of the E-shaped silicon steel sheets, and then placing the I-shaped silicon steel sheets on the E-shaped silicon steel sheets; 5, welding the silicon steel sheets; and 6, conducting weld joint inspection. The transformer silicon steel sheet stacking and welding method has the beneficial effects that the preparation process is reasonable in design, the stacking and welding production efficiency of silicon steel sheet products is high, the protection process is reasonably designed at the same time, product rejection rate is low, the raw material production cost input is also saved, and the manufactured products are excellent and stable in quality.

Description

technical field [0001] The invention belongs to the technical field of application of transformer silicon steel sheets, and in particular relates to a method for stacking and welding transformer silicon steel sheets. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc., and can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators) , mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, transformers, etc.).
