FIELD: electrochemical protection of underground facilities. SUBSTANCE: aggregate has cathode protection station, that has a row of identical channels 1 with input rectifiers 10, storage devices 16, converters 12, summing transformer 13 and output rectifiers 15 and output storing devices 16. Station has prefabricated bars 5, 6, 7, 8, 9, that provide transversal galvanic connections. Signals from current measuring transformers 14 outputs and from comparison electrode 18 output are fed to input of control unit 3. Control unit 3 controls operation of converters 12. EFFECT: increased reliability of aggregate work and quality of protection. 4 cl, 1 dwg |
