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

FIELD: electrical engineering, in particular, power supply units. SUBSTANCE: device has toroidal core, low-voltage winding, which occupies part of toroidal core sector, and high-voltage winding, which is located in sector of toroidal core. Both windings are separated from one another by means of inter-winding insulation. In addition device has electrostatic screen, which is located between windings and is connected to core and ground. Goal of invention is achieved by design of high-voltage winding, which has two members, each of which is located in part of toroidal sector, which is occupied by high-voltage winding. Its terminals are brought out from external side of winding to opposite sides. In addition, transformer has additional electrostatic screen, which is located under high-voltage winding, is connected to its middle tap and is brought out high-voltage winding. Both ends of screen have rounded corners. EFFECT: increased reliability, decreased size. 1 dwg
