STATIONARY INDUCTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a stationary induction apparatus capable of having excellent winding vibration damping performance and insulation performance between coils without thickening a coated insulating material all around the coils.SOLUTION: A stationary induction apparatus includes: an iron core; coils 2, 3 concentrically disposed around the iron core with insulation distances kept between; a plurality of insulation cylinders 22 disposed in insulation spaces formed on the inner and outer peripheries of the coils; a plurality of linear spacers 21 disposed between the insulation cylinders with prescribed intervals kept along a circumferential direction of the coils; inter-coil spacers 19 disposed between the coils in an axial direction thereof to support the coils; and an insulating material 24 disposed in at least one place between the linear spacer and the insulation cylinder in a radial direction thereof.
