| titleOfInvention | Method for preparing epoxy PET insulating cylinder suitable for casting dry-type transformer |
| abstract | The invention discloses a method for preparing an epoxy PET insulating cylinder suitable for casting a dry-type transformer, which comprises the following steps: 1) crushing and crushing PET non-woven fabric to obtain crushed PET short fibers with the length less than 10 mm; 2) baking the PET short fibers; 3) mixing inorganic filler and dispersant to prepare white slurry; 4) mixing epoxy resin, a curing agent, a curing accelerator, white pulp and PET short fibers, wherein the weight percentage of the PET short fibers is controlled to be 9-20%, and preparing an epoxy resin pre-curing system; 5) injecting an epoxy resin pre-curing system into a mold coated with a release agent; 6) putting the processed mould into an oven, solidifying, taking out, cooling and taking down; the insulation cylinder meeting the requirements of the cast dry-type transformer is prepared by a simple process, has excellent mechanical property, electrical property, heat-conducting property and the like at the same time of low cost and low weight, and is energy-saving and environment-friendly. |
