METHOD AND DEVICE FOR TRANSFERRING ELECTRIC ENERGY (VARIANTS) Russian patent published in 2006 - IPC H02J17/00 

FIELD: electric engineering, possible use for transferring electric energy.

SUBSTANCE: transferring of electric energy is performed below ground or below water in resonance mode at resonance frequency 50 Hz - 50 KHz and voltage 1-1000 kV, current density 1-500 A/mm² along one-wire electric-insulated cable, in particular, multi-wired, with length 1-20000 km with section 0,01-1000 cm², cable diameter of which exceeds wire diameter in 5-100 times. In accordance to another variant electric energy is transferred below ground or below water in resonance mode along axial-symmetric one-wire wave duct inside hermetic hollow dielectric cylinder-shaped channel in insulating gas atmosphere, in particular, electronic gas under pressure 1-10 kg/cm². In accordance to yet another variant of method electric energy is transferred along single electro-statically screened and electric-insulated wave duct of surface wave inside the hollow-bodied cylinder-shaped screen and hermetic dielectric channel in atmosphere of insulated gas. High-voltage line may be made below ground or below water in form of one-conductor wave guide with length 1-20000 km, section 0,1-1000 cm, mounted in axial-symmetric manner inside the pipeline with diameter 0,02-10 m made of dielectric material. To increase transferred voltage and power wave guide is made of electric-insulated cable with insulation thickness 3-300 mm, and space between wave guide and pipeline is filled with electric-insulating gas under pressure, for example, electronic gas. High-voltage line is made in form of one-wire wave duct with length 1-20000 km, section 0,01-1000 cm², mounted in axial-symmetric manner inside the pipeline with diameter 0,02-10 m of dielectric material, and contains electric screen, made in form of multiple electric-insulated from each other non-closed conductive cylinder-shaped covers, total length of which is equal to length of wave guide, and length of each conducting cover is 1-1000 meters.

EFFECT: improved efficiency, decreased losses and improved reliability of transferring of electric energy along underground or underwater cable.
