Description

technical field [0001] The invention relates to the field of epoxy resin dry-type transformer production equipment, in particular to an automatic assembly device and an assembly method for dry-type transformer insulation pads. Background technique [0002] Epoxy resin dry-type transformer is a dry-type transformer that uses epoxy resin as the insulating material to encapsulate the coil. And solidified to form high and low voltage coils with high strength FRP body structure. Epoxy resin dry-type transformers are more and more widely used in the transformer industry due to their good electrical performance, strong lightning impact resistance, strong short-circuit resistance, small size, light weight, and low cost. [0003] When the epoxy resin dry-type transformer is running, if the relative position between the low-voltage coil and the high-voltage coil is deviated, it will cause uneven force on the winding in the electromagnetic field, easy to generate noise, and even break...
