COMPLEX OF MODULAR EQUIPMENT FOR ELECTROCHEMICAL CORROSION PROTECTION OF UNDERGROUND AND STEEL STRUCTURES WITH AN INTEGRATED CORROSION MONITORING SYSTEM Russian patent published in 2022 - IPC C23F13/22 

FIELD: chemical processes.

SUBSTANCE: invention relates to the field of electrochemical protection and can be used for protecting underground steel structures from corrosion with simultaneous corrosion monitoring. Complex comprises a modular structure in a system of carrier structures and consists of the main and backup modular cathodic protection converters with power supply modules of the main modular cathodic protection converter and with a power supply module of the backup cathodic protection converter, respectively; an autimatic power voltage switch unit with main and backup electricity metering units; an accumulator battery module connected with the power supply modules of the main modular cathodic protection converter and with the power supply module of the backup cathodic protection converter; and a corrosion monitoring module, as well as a unit for surge overvoltage protection on the supply network side, connected with the power supply modules of the main modular cathodic protection converter; a unit for surge overvoltage protection on the control line side, connected with the corrosion monitoring module and with the main modular cathodic protection converter; and a unit for surge overvoltage protection on the interface line side, connected with the power supply module of the main modular cathodic protection converter, wherein the main and backup modular cathodic protection converters are made in the form of high-frequency pulse power modules with direct digital control.

EFFECT: higher noise resistance and reliability.
