| 摘要 |
FIELD: machine building.SUBSTANCE: invention relates to protection of metal structures against corrosion. This protector comprises collapsible electrode, magnetic element built therein and insulating spacer. Material with one-way conductivity directed from magnetic element to electrode is arranged between them, or dielectric spacer partially isolating contact between electrode and magnetic element is arranged thereat. Note here that contact resistance between electrode and magnetic element does not exceed 10% of the protector impedance.EFFECT: higher protection properties.4 cl, 3 dwg |
