APPARATUS FOR CONNECTING ANODE BUSBAR OF ELECTROLYZER WITH CURRENT LEADING STRUTS Russian patent published in 1995 - IPC

FIELD: non-ferrous metallurgy. SUBSTANCE: apparatus includes a connection assembly of busbars 1,2 with bolts 3, modified by application on one of its ends of weld seam 4, whose length l_w is minimum one and being determined according to expression , where p_w- specific electric resistance of a material of the welded seam; μ torque value at tightening of n bolts with a diameter d of each bolt; l_c, B_c - a length and a width of the contact joint; R₁ and R ₂ electric resistance of busbars, being connected, in contact portions; R_max the most of these resistance values; R₁ and R ₂, K,a,b values, depending upon the material of busbars; C_i coefficient, defining a change of busbar resistance in dependance upon a ratio of a length of the busbar contact portion to its thickness. The apparatus provides a lowering of contact resistance practically by an order in comparison with the apparatus, using a bolt joint. EFFECT: lowered labor consumption and decreased electric energy losses due to lowered voltage drop of the contact joint. 1 cl, 3 dwg
