ABSTRACT:
This transformer comprises a tank containing insulating liquid and an amorphous alloy core within the liquid comprising spaced-apart upper and lower yokes and two spaced-apart legs at opposite ends of the yokes. Coil structure surrounds the legs, locating the yokes outside the coil structure and locating the legs within two windows of the coil structure. A box-like enclosure primarily of electrical insulating material encloses the lower yoke and is positioned to capture therein chips of amorphous alloy that might become detached from the core and fall toward the bottom of the tank.
A first portion of the box-like enclosure extends between the two windows of the coil structure and is held against the bottom of the coil structure. This first portion includes flaps that are folded upwardly into the two coil windows to form liners for these windows, but still leaving clearance space within the windows around the core legs through which detached chips may fall past the liners into the box portion of the enclosure. The box-like enclosure also includes portions which are folded about the lower yoke to form a box that includes said first portion of the enclosure as a lid.
