TRIANGULATED HIGH-CURRENT LEAD Russian patent published in 2015 - IPC H05B7/11 

FIELD: electricity.

SUBSTANCE: invention relates to electrometallurgy. Triangulated high-current lead contains a transformer, three electric holders with electric contact electrode clamps and copper current-carrying and water-cooled tubes fixed rigidly, without electric insulation, in fixtures to sleeves of low-magnetic steel, directly at the outermost phases and brackets at medium phase and placed at peaks of equilateral triangular with sides of optimal dimensions, which are connected by electric contact shoes, parallel strings of flexible water-cooled cable with similar stationary electric contact shoes fixed together with water-cooled bus tubes through damping compensators to transformer terminal leads. Sleeves of the electric holders are fixed at upper ends of vertical posts movable together with reversely movable electrodes, and strings of the flexible cable of outermost phases are equipped with additional cable lines placed in the strings with the main lines equally in circumferential or ellipsoidal direction, similar to placement of lines in the middle phase string; at that quantity of additional cable lines is defined on condition of reduced resistance for strings of outermost phases within the range of 25-65% proportionally to impedance value of the middle phase.

EFFECT: invention reduces costs of electric energy, increases resistivity of lining and ensures high quality of the received product.
