The present invention relates to a coil structure of an open type stereoscopic wound-core dry-type transformer which comprises: coil plates wound by conducting wires and fixing units. Insertion grooves are formed in the fixing units to fix the coil plates. The coil plates are fixed and surrounded by the fixing units to form a coil structure. External layers of the conducting wires are surrounded by insulation paper having insulation paint. By the insulation paint, the coil structure is bonded between the conducting wires and between the coil plates and the fixing units to form an integrated structure. The coil structure does not pass a paint dipping and fixing process to simplify processes. By the insulation paint of the insulation paper, the coil structure is bonded between the conducting wires and between the coil plates and the fixing units to make the structure solid. The coil structure meets requirements for an electric performance, a mechanical performance, and an insulating performance. |
