The method comprises the following steps of: the step 1, material receiving; the step 2, laser marking of a shell; the step 3, primary winding; the step 4, secondary winding; the step 5, foot winding; the step 6,peeling of skin by a laser; the step 7, appearance inspection; the step 8, tin soldering; the step 9, appearance inspection; the step 10, assembling of a magnetic core; the step 11, electrical performance test of a semi-finished product; the step 12, assembling of a housing; the step 13, baking and drying; the step 14, automatic vacuum encapsulation; the step 15, inspection of glue surface; the step 16, appearance inspection of a finished product; the step 17, test of pressure resistance of the finished product; the step 18, electrical performance test of the finished product; and the step 19, package. The preparation process is reasonable in design, the prepared finished product is good in quality, long in service life and high in production efficiency of the product, the production process is reasonable in design, the product rejection rate is low, and the product cost input of raw materials is saved.

Description

technical field [0001] The invention belongs to the technical field of transformer application, and in particular relates to a production process of high-frequency and high-voltage potting and sealing vacuum transformers. 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.). ...
