TRANSFORMER AND TRANSFORMER MACHINING PROCESS
Document Type and Number:
WIPO Patent Application WO/2021/098181
Kind Code:
A1
Abstract:
Disclosed in the present invention are a transformer and a transformer machining process, comprising two coil units arranged side-by-side, each unit comprising an inner coil and an outer coil sleeved on the outside of the inner coil, an outer coil semi-conductive layer being wrapped on the outside of the outer coil and an inner coil semi-conductive layer being wrapped on the outside of the inner coil, and an insulating layer being integrally cast with the coil unit. In the transformer provided by the present application, the arrangement of the outer coil semi-conductive layer and the inner coil semi-conductive layer can effectively improve the problem of excessive local field strength caused by an irregular coil structure and solve the issue of wire package cracking caused by steel material generating heat in a pouring body; thus, the transformer provided by the present invention has improved safety.
