Abstract:
This paper proposes an approach for the design of transformer winding with voltage regulation and interrupting capacity of switch gear. Different from the symmetric winding structure of traditional transformer designs, the proposed method can provide a suitable leakage inductance for voltage regulation and short-circuit current in the transformer. To estimate a satisfactory structural for the winding configuration before manufacture, the leakage inductance is derived from the structural parameters of the transformer. Through the theoretical analyses, the leakage inductance is estimated in the multi-layered structure and a desirable winding configuration is presented that allows the appropriate voltage regulation and short-circuit current. Moreover, the inferential results are successfully obtained substantiation from the experiments.
