Abstract

PURPOSE: To increase the mechanical strength of wave-form side plate, by providing a projected part by bending a side plate in a wave-form and placing metal spacers in the projected chamber.
CONSTITUTION: In order to dissipate the heat produced by the electric apparatus from the tank surface using an insulating oil as medium, wave-form projection 11 is provided on the side surface of the tank and it is fixed by suitable reinforcing member 12. The inside of each projected part 11 is made a projected oil chamber. As heat discharge 13, hollow, rectangular, rod-form metal spacers 16 are placed inside the projected oil chamber. Circular flat spacers 17 may be used instead of rod- form spacers 16. By this, spacers 16, 17 function as supports for the projected parts and prevents the deformation to be caused by the internal pressure of the tank. Hence, it is possible to increase the mechanical strength of the side plates without increasing their thickness.
