HIGH-VOLTAGE INSULATING SYSTEM AND HIGH-VOLTAGE INDUCTION DEVICE CONTAINING SUCH INSULATING SYSTEM Russian patent published in 2016 - IPC H01F27/32 H01F27/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. Insulating system (1-1) contains outermost inner pair (3) of barriers, arranged to cover largest part of windings structure (11) in axial direction (A) inside and outside relative to its turns curvature. At least one barrier of outermost inner pair (3) of barriers sets first flow path (3-1), enabling dielectric fluid (F) to flow, mainly, in first axial direction between windings structure (11) and, at least, one barrier, when insulating system (1-1) is in assembled state. First outer barrier (5) is arranged radially inside or outside relative to each barrier of outermost inner pair of barriers and sets second flow path (5-1) parallel to first flow path (3-1), enabling dielectric fluid (F) flow, mainly, in second axial direction, opposite to first axial direction. Insulating system (1-1) is arranged so, that dielectric medium (F) can flow from second flow path and enter first flow path (3-1) on one axial end section of one of barriers of outermost inner pair (3) of barriers, and at other axial end section of one of barriers of outermost inner pair (3) of barriers exit from corresponding first flow path (3-1). Each barrier of outermost inner pair (3) of barriers has continuous enveloping surface, extending between one axial end section and other axial end section of each barrier of outermost inner pair (3) of barriers.

EFFECT: technical result consists in improvement of insulating property on both ends of winding.
