Title:
METHOD FOR MANUFACTURING POLE-MOUNTED TRANSFORMER USING NO INSULATION OIL AND POLE-MOUNTED TRANSFORMER MANUFACTURED USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/225232
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a pole-mounted transformer using no insulation oil, and a pole-mounted transformer manufactured using same, wherein the transformer uses a solid insulation material and an insulation oil is removed from the transformer, and more specifically, to a method for manufacturing a pole-mounted transformer using no insulation oil and a pole-mounted transformer manufactured using same, the method comprising: a first coil part formation step of winding a low-voltage coil and high-voltage coil to produce a first coil part; a casting step of putting the first coil part into a mold and filling an empty space between the outer peripheral portion of the first coil part and a wound wire with a casting insulation material in a liquid or gel phase, followed by solidification, so as to produce a second coil part; a conductive material attachment step of coupling a conductive material to the outer peripheral surface of the second coil part to produce a third coil part; an iron core coupling step of coupling an iron core to the third coil part; and a transformer completion step of inserting, into an outer case, the third coil part having the iron core coupled thereto to complete a product.
