Claims

[Scope of utility model registration request]

A magnetic shield is installed in the vertical direction of the tank at the location corresponding to the phase center on the inner surface of the tank where the windings are stored.
Corresponding to the interphase part is a magnetic shield tank that is divided into multiple pieces and installed in the longitudinal direction.
An induction electric shielding device characterized in that one or more closed magnetic paths are formed in an interphase portion so as to wrap around the upper and lower sides of a winding.
