Abstract:

A high pressure, high voltage entrance bushing member using taper-sealing between an insulating plastic plug and a metal barrel. Spring loading, as by means of a spring lock washer, is used to urge the taper connections into precompression for proper high pressure fluid-tight seal. Dimensional changes due to temperature variations are accommodated by the taper connections. The high pressure bushing member is used in conjunction with a high temperature, high voltage bushing member, being connected by a conductor extending axially through a high pressure conduit containing a dielectric liquid. The overall entrance bushing assembly is employed in a system for electrically resolving emulsions. In such systems, the dielectric liquid is maintained at the same pressure as the emulsion being treated by means of a dynamic fluid barrier which prevents the intermingling of these liquids.
