Abstract

The present invention discloses a method and system for quickly detecting a cathode short circuit. The method includes: continuously measuring a cathode current; determining whether an increased value of the cathode current in a set time is within a set range of the increased value; if the increased value is within the set range of the increased value, establishing a linear model according to a change of the cathode current with time, and calculating a slope and a determining coefficient according to the linear model; if the increased value is not within the set range of the increased value, determining that the cathode does not have a short circuit; determining whether the slope is within a set slope threshold range; if the slope is within the set slope threshold range, determining whether the determining coefficient is greater than a set determining coefficient threshold; if the slope is not within the set slope threshold range, determining that the cathode does not have a short circuit; if the determining coefficient is greater than or equal to the set determining coefficient threshold, determining that the cathode has a short circuit; and if the determining coefficient is smaller than the set determining coefficient threshold, determining that the cathode does not have a short circuit. The present invention can avoid a sustained short-circuit current loss and improve the electrolysis current efficiency.
