Production process of power-frequency encapsulated transformer

Abstract

The invention belongs to the technical field of transformer application, and particularly discloses a production process of a power-frequency encapsulated transformer. The process comprises the following steps: 1, material taking; 2, primary winding; 3, secondary winding; 4, tin soldering; 5, appearance inspection; 6, turn-to-turn voltage withstand test; 7, silicon steel sheet assembling; 8, argonarc welding; 9, voltage withstanding test on a semi-finished product; 10, testing of the electrical performance of the semi-finished product; 11, assembling of a shell; 12, baking and drying; 13, automatic vacuum filling and sealing; 14, glue surface inspection; 15, inspecting of the appearance of a finished product; 16, frequency doubling and voltage doubling test of the finished product; 17, voltage withstanding test on the finished product; 18, testing of the electrical performance of the finished product; 19, packaging. The invention has the beneficial effects that the preparation processis reasonable in design; the prepared product is excellent in quality, long in service life and high in production efficiency; meanwhile, the rejection rate of the product is low, and the productioncost 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 a power frequency potting and sealing transformer. 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.). [0003] The fundamental...
