ELECTRIC ANTICORROSION SYSTEM, AND ELECTRIC ANTICORROSION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electric anticorrosion system in which a supply voltage can be controlled without performing construction work on an object to be protected against corrosion and to provide an electric anticorrosion method using the electric anticorrosion system.SOLUTION: The electric anticorrosion system 1 includes: a piezoelectric element 3 for generating electricity when receiving an external load; an energizing electrode 4 for supplying an anticorrosive current to the object 2 to be protected against corrosion; a control unit 6 for controlling the anticorrosive current to be supplied to the energizing electrode; a reference electrode 7 for outputting a constant potential to the control unit; and an information display terminal 8 for displaying the potential to be outputted from/inputted into the control unit and the information on the anticorrosive current. The control unit has: a means 65 for determining a potential between the reference electrode and the ground; a menas 66 for determining an anticorrosive potential; a means 67 for acquiring a potential between the object to be protected against corrosion and the ground; a determination means 68 for determining whether a difference between the potential between the object to be protected against corrosion and the ground and the potential between the reference electrode and the ground is equal to a difference between a target anticorrosive potential and the potential between the reference electrode and the ground; and an anticorrosive current adjustment means 69 for adjusting the intensity of the anticorrosive current so that both of the differences become equal to each other when the determination means determines that both are not equal to each other.
