Abstract
The invention discloses a resin-insulation coil of a dry type transformer, which is simple in structure and fine in electric insulation performance and comprises an electromagnetic wire turn. High-performance polyester film layers are arranged on the inner side and the outer side of the electromagnetic turn, and epoxy resin layers are arranged on the upper side and the lower side of the electromagnetic turn respectively. The resin-insulation coil has the advantages that the resin-insulation coil is simple in structure and fine in electric insulation performance, usage of epoxy resin is reduced, production process is simplified, production cycle is shortened, only inner dies are needed on the investment of moulds, and production cost is reduced.
Description
Technical field
The present invention relates to a kind of parts of transformer, relate in particular to a kind of resin insulating dry type transformer coil.
