SMART DEVICE OF CATHODE PROTECTION WITH CONTROL OF THE CORROSION PROCESS OF A GROUP OF UNDERGROUND METAL STRUCTURES Russian patent published in 2022 - IPC C23F13/02 

FIELD: corrosion protection.

SUBSTANCE: invention relates to the field of corrosion protection and can be used to protect gas pipelines, oil pipelines and other underground metal structures when they run in the area of ​​movement of rail electric transport. The device contains a transformer, a rectifier, a filter, anode earthing switches of the main and additional metal structures, power switches, valves, filters, integrators, modulators, sensors and generators of protective potential, comparison units, correctors, scaling amplifiers, sensors of entry and exit of the protection zone by electric transport, blocks radio broadcasts, triggers, adder, memory blocks, correction registers, corrosion control elements, totalizers for calculating the action of corrosion, integral corrosion correctors for the potential of the main and additional protected structures.

EFFECT: increasing the efficiency of cathodic corrosion protection by monitoring the amount of corrosion in real time and correcting the values ​​of protective currents in the protected area of ​​underground metal structures from the amount of real corrosion and the nature of the movement of electric rail vehicles in the area of ​​their running.
