    摘要: A method for protection against overloads in mercury cathode electrolytic cells, consisting in detecting, in an indirect way, the average currents of the two semicells forming the cell to be protected by measuring the average of the anode potentials of the two semicells with respect to the two average potentials of the two semibottoms of the next cell, via a bridge circuit connecting said two average potentials of the semicells with said two average potentials of the semibottoms of the next cell, and in obtaining, with a balanced cell, two signals of bridge unbalance, by connecting in said bridge two double potentiometers having only one control, such as to actuate alarm devices when, because of overloaded anodes or of current unbalances, the value of one of said signals is zero. A device for carrying out this method consists of bridge electric circuits, with a double potentiometer for working out signals, as well as contact-connected alarm thresholds for setting in action alarm and/or anode-lifting devices.
