Enhancing Corrosion Resistance of Copper for C <sub>4</sub> F <sub>7</sub> N Based Eco‐Friendly Gas‐Insulated Equipment
ABSTRACT Perfluoroisobutyronitrile (C 4 F 7 N) is recognised as the next‐generation dielectric medium for eco‐friendly gas‐insulated equipment (GIE). However, there is gas metal incompatibility in strong electromagnetic environments and environmentally friendly insulating gas atmospheres that endangers the operational safety and service life of GIE. Here, a solvent‐induced grain boundary reconstruction method was proposed to prepare corrosion‐resistant copper rapidly. Accordingly, the partial discharge‐induced gas–metal interaction was simulated and the corrosion resistance properties of copper were evaluated. Additionally, the gas–solid interaction mechanism was investigated and the improvement mechanism of the proposed method on the stability of the gas–solid interface was discussed. Related results provide a reference for the development and application reliability of C 4 F 7 N‐based eco‐friendly GIE.
