Winding for static induction apparatus

摘要: A winding for a static induction apparatus such as transformer, reactor and the like comprises plurality of interleaved coils each formed by an electrically insulated strand conductor in radial spiral. The are stacked axially connected series between line terminal another neutral terminal. is divided into blocks including ones coils. number turns coil belonging to block on other side decreased compared with that located closer terminal, thereby reduce electrostatic capacitance stepwise from one starting side. distribution constant thus decreased. Favorable surge withstanding characteristics attained, reliable insulation assured can be realized reduced size.
