摘要

FIELD: construction. SUBSTANCE: novelty consists in that for establishment of complex of anticorrosive cathodic protection, anode earth, comparison and auxiliary electrodes are buries in ground near, at least, one part of metallic and/or metal-containing objects of protection; at least one converter substation is installed in places corresponding to operating conditions from the point of view of weather, geographic and geophysical factors. Converter substation is in the form of casing protected from weather effect and sun rays. Laid between converter substation and protected object are electrical power and measuring circuits. Introduced into the converter substation are limit switches of the indicated circuits, boards and panels where units and elements of electrical equipment of converter substation are mounted, which form generator of protective potentials and including power unit based on power source of direct current ensuring supply between protected object and anode earth electrode of difference of protective potentials, control system with functional units including unit for separation of controlled potentials and unit for control and protection, and input control unit with switch of, at least, three modes of protection. Ends of indication circuits with leads of generator of protective potentials of converter substation, and their other ends with protected object, anode earth, comparison and auxiliary electrodes. Units and elements of generator of protective potentials are connected with one another and with circuits to form depending on actual potentials on protected object and both electrodes, respective protective potential on protected object. Units of control and protection and, at least, one more unit of control system are mounted on one common panel, and all other units and elements of generator of protective potentials of converter substation are mounted on other panel. EFFECT: higher reliability of protection from corrosion with simultaneous reduction of volume of earth work, labor input and material consumption. 96 cl, 15 dwg electrode, ce
