The principle of operation of IPKZ in the cathodic protection system
The IPKZ-MS-RA® cathodic protection converter is based on high-frequency pulse converters.
Converts alternating current into direct current and supplies the desired potential to the protected elements, suppressing corrosion processes.
They are operated in the electrochemical protection circuit (ECZ) according to the principle of operation of the cathodic protection system by the superimposed current method. The method is based on shifting the potential of the steel casing of the hull of a marine structure in the negative direction until the chemical non-reactivity of the metal or its thermodynamic stability is achieved. → Anodes are installed on the underwater part of the metal structure, to which a constant electric current is supplied from external power sources, going to the cathodic polarization of the metal surface → The underwater part of the housing becomes one large cathode and under the influence of polarization, the potential of the metal surface shifts in the negative direction to protective values.
The key characteristic of the system is the possibility of automatic fixation of the electric potential on the surface of the protected object and a corresponding increase or decrease in the output current from the anode. Thus, the object receives a constant optimal level of protection.
The electric potential is fixed by control silver chloride electrodes located between the anodes, where the lowest potential should be.
The data is captured by the reference electrodes and transmitted back to the IPKZ control panel. The converter, in turn, automatically adjusts the output current from the anode.
Thus, the cathode system suppresses and neutralizes corrosion processes on a submerged object.
All parameters of the converter │ SKZ are determined during the development of the cathodic protection project.
