ABSTRACT:
The system is foreseen to cathodically protect the submerged metal structure of ships by using the printed current technique, that is to say, applying a negative potential to the steel structure until placing it at a potential of -800 mv. A photovoltaic cell (1) connected to the battery (3) of the ship (Z) with the insertion of a charge regulator (5) is used as an energy source, the system including an automatic current regulator (6) applicable to the respective anode (7.) The negative output (4') of said regulator is connected to the metal parts such as the propeller (8), and rudder (9), while the positive output (4") or cable is connected to the anode itself (7), the latter consisting of an airproof box in which the cable itself (4") connects to the titanium band that comprises the anode itself, by means of a Faston type terminal, complemented with double insulation, a thermoretractile sleeve and some end covers that ensure the total sealing of the connection. The automatic regulator (6) provides a voltage of 2 volts at the output and an increase of amperage, regarding the input, in order to attain the correct cathodic protection of the metal parts to which the system is applied.
