Abstract
The present disclosure discloses a coil structure for a dry-type transformer and a winding method therefor. The coil structure for a dry-type transformer comprises multiple coil layers and a supporting framework, which is provided with multiple supporting layers. The spacer blocks of each intermediate supporting layer comprise a rising spacer block for rising and supporting spacer blocks in addition to the rising spacer block, a thickness of the rising spacer block being greater than a thickness of the supporting spacer block, and the rising spacer blocks of several intermediate supporting layers being staggered along the circumferential direction. The present disclosure decreases the height of the entire coil efficiently, meanwhile abates the problem that the wire is centralized in a single area, inhibits the temperature rise phenomenon of transformers efficiently, and prolongs the lifetime of transformers.
