Stationary induction apparatus
Abstract:
A stationary induction apparatus includes a main body tank and a stationary induction apparatus main body. The main body is accommodated in the tank. An electrostatic shield ring is placed on the upper and lower end parts of a winding. An electrostatic shield ring has a magnetic ring and two insulating rings vertically fixing the magnetic ring for a spool. A conductive tape is laid on an insulating tape. These tapes are wound around the spool. An insulating tape is wound around the wound tapes. The width of the insulating tape is equal to or greater than the width of the conductive tape. One end of the conductive tape is connected to one end part of the winding and to the magnetic ring. A gap is provided at at least one place on the magnetic ring. The winding direction of the conductive tape is inverted at at least one place.
