Abstract

Procedeu de compensare a cîmpurilor magnetice ale firelor vecine de la cuvele de electroliza arsa, plasate transversal prin care se modifica repartitia curentului în conducatorii de alimentare ai anodului unei cuve amonte vecine astfel încît se suprapune peste o cuva o bucla electrica producînd un cîmp magnetic suplimentar sensibil egal cu cel creat prin firul vecin si de sens contrar caracterizat prin aceea ca bucla electrica produce efectul de compensare pe capul exterior al cuvei de electroliza. Dispozitivul de compensare a cîmpurilor magnetice ale firelor vecine de la cuvele de electroliza, caracterizat prin aceea ca bucla de compensare se formeaza facînd sa treaca printr-un conductor de compensare, o fractiune de curent care parcurge colectorul negativ exterior amonte, întîlnind apoi acelasi colector amonte mergînd de-a lungul laturii mari a cuvei.
