Title:
METHOD OF MANUFACTURING GROUND-BURIAL TYPE SOLID INSULATED TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2010/024617
Kind Code:
A2
Abstract:
The present invention relates to a manufacturing method for a ground-burial-type solid insulated transformer. More specifically, the method produces a transformer which avoids shocking humans and livestock that come into contact with its external casing. Shocks are avoided through use of a shell made of a polymeric compound which easily cools the transformer and which does not corrode even after long-term under ground. The invention comprises a first process wherein a coil form is prepared to form an inner window; a second process wherein a low-voltage coil and high-voltage coil are wound on said coil form creating a first coil part; a third process wherein glass fiber is wound on said first coil part creating a second coil part, and a mold formed to correspond to said inner window and inserted therein before said second coil part is heated; a fourth process wherein the second coil part into which said mold has been inserted is placed in the mold, and an epoxy resin and a curing agent are injected thereby forming a third coil part under vacuum, pressure, and temperature; a fifth process wherein said third coil part undergoes automatic mold-curing, and said mold is separated from said inner window before said third coil part is subjected to post-treatment curing; a sixth process wherein said third coil part is cooled, sanded and washed, and a semiconducting coating agent is applied creating a fourth coil part; a seventh process wherein a core is assembled at said fourth coil part to creating a fifth coil part, and said fifth coil part is tested; an eighth process wherein a conductive mesh is combined with said fifth coil part, a shell assembled and a silicone or polymer compound is filled between said fifth coil part and said shell; and a ninth process wherein the completed transformer is tested.
