Abstract

549,767. Transformers. AKT.-GES. BROWN, BOVERI & CIE. Jan. 20, 1942, No. 836. Convention date, Feb. 12, 1941. [Class 38 (ii)] In a high voltage transformer with sandwichtype windings, the stacks of high voltage coils b<SP>1</SP> are surrounded by insulation d between which and the core a is disposed an earthed electrode m. The latter is extended outwardly between the low voltage sections c<SP>1</SP>, c<SP>2</SP> and terminates in rounded edges m<SP>1</SP>, m<SP>2</SP>. Complementary screening rings g<SP>1</SP>, g<SP>2</SP> are provided on the inside of the insulation where it leaves the winding. Passages e are provided at diametrically opposite points on the insulation to permit circulation of cooling fluid through the high voltage winding.
