Abstract

FIELD: electrical and radio engineering.
SUBSTANCE: proposed high-voltage conductor designed for erecting dc and ac power transmission lines and also for use as conductor of heavy-power low-frequency radio transmitting antennas has concentrically disposed weight carrying member, radius R1 conductor, internal semiconductor insulating layer, external semiconductor insulating layer, and radius Re main insulating layer. Internal semiconductor insulating layer is required for fashioning current-carrying conductor in the form of round cylinder and for smoothing down irregularities capable of enhancing electric field strength and liable to cause partial discharges. External semiconductor insulating layer is used for fast equalization of potential throughout entire external surface of conductor. Operating voltage across conductor may exceed corona firing potential Vc in vicinity of insulator-air boundary by 1.4 to 3 times at specified corona power loss. Novelty is that relative radius x = Re/R1 and volume resistivity ρ of main insulating layer in high-voltage conductor with known corona-discharge current-voltage characteristic I(V1) and at specified corona power loss are interrelated by definite equations for frequencies f > fb and f < fb, where fb is value reverse to charge time constant of circuit set up of corona discharge resistance and total capacitance of system.
EFFECT: ability of conductor operation at voltage exceeding corona firing voltage near certain boundary.
