Reactance formula switching transformer

The utility model belongs to the technical field of the power equipment technique and specifically relates to reactance formula switching transformer, including a main coil, a secondary coil and the first iron core of setting between a main coil, a secondary coil, a main coil goes up and connects adjustable reactor through the wire, adjustable reactor includes the 2nd main coil, the 2nd main coil,be provided with the second iron core between the 2nd main coil, the 2nd secondary coil, the 2nd secondary coil goes up through wire parallel connection multiple coils, connect electromagnetic relaythrough wire series on the coil, this reactance formula switching transformer has realized the mesh of a regulating transformer main coil reactance to a transformer main coil is absolute constructionwith adjustable reactor, makes whole transformer structurally relatively disperse, has reduced the design degree of difficulty, has reduced manufacturing cost, has adopted adjustable reactor switch simultaneously, and the use a
