DEVICE FOR CATHODE PROTECTION OF EXTENDED SECTION OF UNDERGROUND STRUCTURE Russian patent published in 2014 - IPC C23F13/02 

FIELD: electricity.

SUBSTANCE: invention refers to the sphere of electrochemical protection for underground metal structures from corrosion, in particular to protection of pipelines. Device contains cathodic protection station is equipped with output voltage sensor and anode bed and the station can be connected to the protected facility through output current sensor; tracking station that can be connected to output voltage sensor and output current sensor and cathodic protection station; test station located close to cathodic protection station; the test station includes potential probe and potential metre connected to the probe, facility and tracking station; at that device contains additionally at least two test points connected to the power supply source which are remote from cathodic protection station and located at the protection zone boundary of cathodic protection station at its both sides along the protected facility; at that tracking station is equipped with central transceiver and each remote test station is equipped with resident transceiver connected to the central transceiver though communication channel.

EFFECT: improving efficiency of anticorrosion protection with reduction of power expenditures.
