High power pulse transformer for short high-voltage and/or high-current pulses

摘要

High-power pulse transformer for short pulses of high voltage and / or high currents, preferably for circuits of high-power lasers (L). The winding conductors (l1, l2; l10, l20) of the low and high voltage winding (w1, w2) have with their surfaces a high heat transfer coefficient (α) with respect to a liquid dielectric. The turns (w01, w02) of the low and high voltage winding (w1, w2) are self-supporting with a first minimum distance (a) between the turns and with a second minimum distance (b) to the magnetic core (M1) wrapped around them and nested bifilar , and immerse in an insulating, cooling dielectric liquid. Post insulators (1.1, 1.2) are arranged adjacent to at least one of the sides of the magnetic core at a third minimum distance (c) (b + d), with (b) the second minimum distance and (d) the conductor thickness of the turns (w1, w2) means and wherein at least the winding ends (a11 to a26) of the low and high voltage winding are trapped in recesses (2) of the support insulators (1.1, 1.2). Furthermore, means (4, 6, 7, 8, 9) for holding the magnetic core (M1) and the support insulators (1.1, 1.2) on a base plate (3) within a container containing the dielectric liquid and high-voltage bushings for the connection ends of the winding conductors provided the container walls.
