HIGH-VOLTAGE HIGH-FREQUENCY TRANSFORMER Russian patent published in 2000 - IPC

FIELD: electrical engineering. SUBSTANCE: invention refers specifically to high-voltage high- frequency transformers with solid insulation and intensive cooling, predominantly, liquid, that can be used in the capacity of high-voltage power supply sources of various assignment Proposed high-voltage high-frequency transformer has at least one toroidal magnetic core encapsulated in hollow coolers forming magnetic system that carries windings with solid insulation and sector not occupied by one winding where leads of one winding and branch pipes for inlet and outlet of cooling agent are located. Hollow coolers are manufactured in the form of diamagnetic hollow rings put on external butts of toroidal magnetic core, their spaces having baffles and holes. In this case holes are located on both sides of baffle on external generatrix of ring. Spaces of rings intercommunicate in sequence. EFFECT: enhanced operational reliability, reduced dimensions and simplified manufacturing process. 1 cl, 7 dwg
