Latest Patents
One of Hoshi's latest patents involves a winding for static induction apparatus, such as transformers and reactors. This innovative winding comprises a plurality of interleaved coils, each formed by winding an electrically insulated strand conductor in a radial spiral. The coils are stacked axially and electrically connected in series between a line terminal and another terminal, such as a neutral terminal. The winding is divided into several blocks, each containing multiple interleaved coils. Notably, the number of turns of each coil belonging to the block on the other terminal side is decreased compared to that of each coil in the block closer to the line terminal. This design reduces the series electrostatic capacitance of the coils stepwise from one block to another, starting from the one located on the line terminal side. As a result, the distribution constant is decreased, leading to favorable surge withstanding characteristics, reliable insulation, and a reduced size for the winding.
