Abstract

PURPOSE: To reduce loss due to leakage flux of lower core clamp only having the function of supporting the winding by reducing the width of upper plate on the clamp.
CONSTITUTION: A lower insulated ring 5 supporting windings 2 and 3 wound on the core 1 is provided on an upper plate 7A of a lower core clamp with a reduced width. an insulated plate 16 is inserted into a groove 19 provided thereoutside. The outside of the insulated plate 16 is fixed to a mount plate 27 extended on the lower inner wall of an oil tank with a bolt 18. The insulated plate 16 divides the oil tank 13 into the upper and lower parts. an insulating oil enters the windings 2 and 3 from a lower piping 11 via an oil inlet 8 for cooling. With such an arrangement, it is possible to reduce loss due to leakage flux caused in the lower core clamp.
