Abstract:
A plug-in-type high-voltage bushing assembly having a body portion formed of a cast resin insulation system, and a conductor assembly. The conductor assembly includes a conductor, a pressure type terminal disposed on one end of the conductor, and resilient, compressible means disposed about the pressure terminal. The conductor assembly is embedded in the cast resin system of the body portion, with the conductor and resilient compressible means being in contact with the cast resin system. The resilient means surrounds and protects the pressure terminal from the cast resin, enabling the pressure terminal to retain its ability to provide tight electrical joints with a mating plug-in connector, while being surrounded by the cast solid insulation system of the body portion of the bushing.
Abstract:
A transformer coil comprising a low voltage winding and an inner concentric high voltage winding. The windings being provided by winding on itself a plurality of layers of sheet conductor having a thin insulation coating thereon. Leads for the high voltage winding are brought out of the coil through an opening in the low voltage winding or closely adjacent the low voltage winding and the windings are cast into a resin housing so that the resin housing surrounds the windings and the high voltage leads. The cast resin braces the high voltage leads against the low voltage windings and provides a long leakage path from the voltage leads to points of a different ground potential.
