FIELD: electric engineering. SUBSTANCE: device has support insulator 1, metal housing 2 which is located on insulator and has cylinder 3 which passes coils of primary winding 4. Internal and external ring secondary windings 5 and 6 are located inside housing 2 in coaxial about cylinder 3 and each other. Said secondary windings are mounted by means of insulation member 7. Ratio of total axial size of external secondary windings to total axial size of inner windings is in range of 0.5-0.7. This results in maximal (70-80%) fill of space which is cut but insulation gaps between secondary windings, which are connected to ground potential, and housing, which is connected to heavy voltage. This ratio holds for various sizes of insulation gaps and radial sizes of external and internal secondary windings. EFFECT: increased functional capabilities. 5 cl, 5 dwg |
