MOLDED TRANSFORMER Russian patent published in 1997 - IPC

FIELD: electrical engineering; epoxy-insulated high-voltage transformers. SUBSTANCE: transformer has magnetic cores placed in molded case, low- and high-voltage windings, low- and high- voltage conducting screens around low- and high-voltage windings, respectively, and additional screen; novelty is that additional screen is semiconducting and placed between case and low-voltage screen so that it embraced upper part of low-voltage screen and its lower end is on one fifth to two fifths level of transformer height from its base which is grounded. EFFECT: improved design. 1 dwg
