PROTECTOR Russian patent published in 1995 - IPC

FIELD: corrosion protection. SUBSTANCE: protector has electrode 1 with core 2. Electrode 1 is made from electrochemically active material with electronic conductance, electrolytic activator 3 in contact with electrode 1, electroconductive enclosure 4 and current input 5 connected with core 3. Electrode, activator and enclosure are composed of n number of parts. Parts of electrode have no direct electric contact. Direct contact is provided between respective parts of electrode-activator and activator- enclosure. Enclosure is manufactured from material different from that of electrode 1. At least one current lead is connected to core of first part of electrode 1. Each 1st (1-1,2,3.) part of enclosure is electrically connected with 1-1 part of electrode by conductor 6 or it is in contact with the whole inner surface of 1-1 part of electrode. Respective parts of electrode, activator and enclosure may be separated by dielectric layer 7 in the form of walls, disks, removable end members 9, which prevent short-circuiting of separate parts of protector through ground. End part of enclosure may be provided with high-conductance flexible cable Protector may be formed as flexible cable. Terminating part of enclosure may be covered from outside by housing manufactured from material with electronic conductance, whose potential value is such that generation of counter-electromotive force in galvanic pair with construction metal is prevented. EFFECT: stable electromotive force in wide range of values (4-6 V), reduced dimensions, simplified construction, availability of material. 7 cl, 7 dwg
