Electrodeposition is an electrochemical process by which it is possible to cover a piece with a thin layer of a certain metal. To achieve this, the piece to be covered is immersed in an electrolytic solution that contains the ions of the metal that will form the layer.
The piece is placed in contact with a source of direct current and with an electrode that will fulfill the function of anode, yielding electrons so that the metal ions in the solution are reduced and deposited on the piece, which fulfills the function of cathode, this way you get the metallic coating on the piece.
To carry out the electrodeposition process, specialized facilities called electrolytic cells are required, equipped with an electrical circuit system that circulates a continuous and low intensity electric current.
Normally, the electrical connections of the electrolytic cells are very simple, since it is intended to reduce the paths, in direct current and high voltage, from the rectifiers of current to the banks of cells.
In general, the connection is made with copper bars, which are fixed and have spacers to allow internal circulation of air and thus improve cooling, these bars are also known by their English name: bus-bars.
When placing the cells in series, only one connection is required at the ends of the bank of cells, if at the end of the first bank, they are connected with a single conductor to the bank in parallel to cells in the side, the path from the rectifier is shorter.
In ecn we have developed a short-circuit detection system in electrolysis cells since this process demands a large amount of electrical energy and its main cause of inefficiency is due to the short circuits that occur between anode and cathode.
This system is based on thermovision for the detection of hot spots by continuous monitoring in the electrolytic cells, and provides an effective solution for the early detection of short circuits, for a better use of energy, increasing the quality of the product and reducing thetimes of maintenance.
