GALVANIC CORROSION SUPPRESSION METHOD, GROUNDING WIRE APPARATUS AND GROUNDING SYSTEM

摘要

Embodiments of the present invention provide a galvanic corrosion inhibition method, a ground cable apparatus, and a grounding system, and relate to the field of electronic technologies, resolving a problem that existing galvanic corrosion inhibition solutions have excessively high costs or a poor effect. The ground cable apparatus includes: an isolation and protection module and a first metallic device made of a first metal or a second metallic device made of a second metal, where one end of the isolation and protection module is equipotentially connected to the first metallic device, and the other end of the isolation and protection module is equipotentially connected to the second metallic device; when a potential difference between the first metallic device and the second metallic device is less than a preset switching voltage, the isolation and protection module is in an open-circuit state or in a high-impedance state; and when a potential difference between the first metallic device and the second metallic device is greater than or equal to the switching voltage, the isolation and protection module is in a conducting state or in a low-impedance state. The embodiments of the present invention are applied to galvanic corrosion inhibition.
