Abstract

The invention discloses a method and system for rapidly detecting a cathode short circuit. The method comprises the following steps: continuously measuring cathode current; judging whether an added value of the cathode current in pre-set time is in a pre-set added value range or not; if so, establishing a linear model according to changes of the cathode current along time and calculating a slope and a determination coefficient according to the linear model; if not, judging that the cathode is not short-circuited; judging whether the slope is in a pre-set slope threshold value range; if so, judging whether the determination coefficient is greater than a pre-set determination coefficient threshold value or not; if not, judging that the cathode is not short-circuited; if the determination coefficient is greater than or equal to the pre-set determination coefficient threshold value, judging that the cathode is short-circuited; if the determination coefficient is less than the pre-set determination coefficient threshold value, judging that the cathode is not short-circuited. By adopting the method and the system, disclosed by the invention, lasting short-circuit current loss can be avoided and the electrolytic current efficiency is improved.

Description

technical field [0001] The invention relates to the field of short circuit detection, in particular to a method and system for quickly detecting cathode short circuit. Background technique [0002] In the industrial production process of electrolytic refining and electrolytic deposition of copper, lead, zinc, nickel, manganese and other metals in aqueous solution, generally a single electrolytic cell contains dozens of anodes and a corresponding number of cathodes, and the anode plates and cathode plates are arranged side by side. The anode and cathode of the electrolytic cell are both plate-shaped, called anode plate and cathode plate, with a single surface area of ​​1m 2 Above, a single electrode can pass a current of more than 500A. Due to the narrow space between the cathode and the anode on the electrolytic cell, and the distance between the electrodes is tens of millimeters, local deformation on the electrode surface may cause uneven distribution of current on the ele...
