ADAPTIVE STATION OF CATHODE CORROSION PROTECTION OF PIPELINES Russian patent published in 2012 - IPC C23F13/02 

FIELD: electrical engeneering.

SUBSTANCE: invention refers to the area of corrosion protection of underground metallic constructions. The station includes valve-type arresters, automatic shutdown device, power unit, shunt, indicator of protective polarization potential, current sensor, voltage sensor, first and second current reference-input elements, voltage reference-input element, divider, first and second resistance reference-input elements, first, second and third potential reference-input element, first and second current comparison units, voltage comparison unit, first and second resistance comparison units, first, second and third potential comparison units, high-resistivity amplifier, multiinput element OR with Schmitt trigger logic on each input, univibrator, first and second keys, direct-current converter, memory module, solid-state relay, cellular communication module with a set of information inputs and outputs.

EFFECT: use of the invention provides for increased effectiveness of pipelines corrosion protection by constant control of technologic parameters being in accessible range and producing of emergency signal in case of its violation with information being transferred to control center using cellular communication.
