摘要

全氟异丁腈（C4F7N）被认为是环保气体绝缘设备（GIE）的下一代介电介质。然而，在强电磁环境和环保绝缘气体环境中存在气体金属不相容性，危及GIE的运行安全和使用寿命。本文提出了一种溶剂诱导晶界重建方法来快速制备耐腐蚀铜。在此基础上，模拟了局部放电诱发的气-金属相互作用，并对铜的耐腐蚀性能进行了评价。研究了气固相互作用机理，探讨了该方法提高气固界面稳定性的机理。相关研究结果为基于c4f7n的生态GIE的发展和应用可靠性提供了参考。

Enhancing Corrosion Resistance of Copper for C4F7N Based Eco-Friendly Gas-Insulated Equipment

Perfluoroisobutyronitrile (C₄F₇N) 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 C₄F₇N-based eco-friendly GIE.
