Information × Registration Number 0221U100900, 0119U101786 , R & D reports Title Development of the energy-efficient system of contour shielding of the magnetic field of high-voltage cable lines for the zones of the coupling joints. popup.stage_title Head Rozov Volodymyr Yu., Registration Date 11-01-2021 Organization State Institution "Institute technical problems magnetism of the National academy of sciences of Ukraine" popup.description2  Experimental studies of the laboratory model of the contour shielding system (CSS) were carried out, the results of which confirmed the high efficiency of shielding of the magnetic field (MP) of cable lines (CL) (about 7 units at a normalization height of 2 m) and correspond to the basic theoretical positions obtained in research topic "Improving the efficiency of contour shielding of the magnetic field of three-phase cable lines in the areas of couplings" ("SUPERCAB"), performed by the Institute in 2019 according to KPKVK 6541230. Distancing from the CL of the screen circuit with its asymmetric magnetic connection with CL cables with a ferromagnetic core with adjustable magnetic parameters allowed to reduce the current in the screen circuit to 30-50% of the rated current of the CL, thereby significantly reducing energy losses in the screen and virtually eliminate its thermal effect on the current capacity of the CL. According to the research results, technical requirements have been developed for the prototype of CSS MP of high energy efficiency, at which at the final stage of the project it is planned to work out the main practical aspects of implementation of energy efficient CSS, including methods of regulating magnetic parameters of the core.
