ARRANGEMENT FOR CATHODIC PROTECTION AGAINST ATMOSPHERIC CORROSION OF METALLIC STRUCTURES Russian patent published in 1997 - IPC

FIELD: corrosion protection. SUBSTANCE: arrangement designed to protect metallic structures having no contact with ground (e.g., vehicles) consists of one main and auxiliary containers with electrolyte and mounted therein anodes made as elbow of a metal having more negative potential than that of metallic structure and directly linked up to the latter, which has no contact with electrolyte. Arrangement further contains a power source linked up to anodes, their surface area constituting 0.5% that of metallic structure; voltage sensor; control device; commutation switch; and circuit switch. Voltage sensor is inked up successively with metallic structure, and control device is linked up to voltage sensor, power source, and commutation switch, the latter being mechanically connected with circuit switches, each linking up a certain container with electrolyte and anode to power source. EFFECT: improved design. 1 dwg
