HIGH VOLTAGE IMPULSE TRANSFORMER Russian patent published in 2006 - IPC H01F19/08 H01F27/32 

FIELD: electric engineering, in particular, impulse engineering, possible use in input separating circuits of grid high voltage impulse modulators.

SUBSTANCE: high voltage transformer contains ring-shaped magnetic duct, positioned in the pressurized body, ends of which are made with shelves in form of radial segments, between which primary windings are positioned. Inter-winding isolation is made of epoxide compound of toroidal shape with radial shelves on its end surfaces. Between shelves, secondary windings are positioned. Through shelves of one end surface of inter-winding isolation, outputs of primary windings are passed. In shelves of another end surface, outputs of secondary windings are held. Primary and secondary windings are positioned inside the body of high voltage isolator coaxially with the latter. Outputs of primary windings are made of lengths of circular conductor, one ends of which are electrically connected to ends of primary windings are held on the pressurized body. Other ends of outputs are bent in radial direction at an angle of 90° and mechanically and electrically connected to ends of current-conductive pins, positioned inside the body of high-voltage isolator. Adjacent outputs of secondary windings having different potentials are bent similarly to current-conductive pins of high-voltage isolator. On the inner surface of inter-winding isolation between secondary windings having different potentials, one groove is made, parallel to axis of the transformer. On its external surface, another groove is made, positioned diametrically oppositely to the first one. Internal gaps between body of high-voltage isolator, transformer, pins and outputs are filled with aforementioned epoxide compound.

EFFECT: expanded range of frequencies of transformed signals, facilitated operation conditions due to abolishment of liquid dielectric.
