Abstract

A transformer comprises a tank containing insulating liquid, and within the liquid there is an amorphous-alloy laminated core that comprises 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. Box-like enclosures primarily of electrical insulating material respectively enclose the yokes in positions outside the coil structure. The enclosure about the lower yoke is positioned to capture therein chips of amorphous alloy which might become detached from said core and fall toward the bottom of the tank.
