TLDR
In this article, a high-power pulse transformer for short, highvoltage and/or high-current pulses is described, where a base plate in a container, an insulating, cooling dielectric liquid with a given heat transfer coefficient in the container, at least one magnet core on the base plate with self-enclosed magnet legs around a central window and wide sides with axes normal to the axis of the window.Abstract:
A high-power pulse transformer for short, high-voltage and/or high-current pulses includes: a base plate in a container, an insulating, cooling dielectric liquid with a given heat transfer coefficient in the container; at least one magnet core on the base plate with self-enclosed magnet legs around a central window and wide sides with axes normal to the axis of the window; at least an undervoltage and an overvoltage winding in the liquid wrapped in each other around parts of the magnet core immersed in the liquid and linked to the magnet core and to each other, the windings including turns of substantially mutually doubly-wound electrically insulated metallic conductors having winding ends disposed in leadthroughs in the container walls, the conductors having surfaces with a heat transfer coefficient higher than that of the dielectric liquid; the turns of each winding being self-supported and spaced apart from the turns of the other winding by a first minimum spacing and spaced from the magnet core by a second minimum spacing; support insulators partly disposed in the liquid and adjacent and spaced from at least one side of the magnet core by a third minimum spacing being greater than the sum of the second minimum spacing and the thickness of the turns, at least the ends of the windings being secured in recesses formed in the support insulators; and a device for retaining the magnet core and the support insulators on the base plate.read more
