摘要
户外气体绝缘金属封闭开关设备根据使用环境的不同,需要具备良好的防腐性能。本文首先对户外气体绝缘金属封闭开关设备的黑色金属零件防腐情况进行了梳理,对腐蚀多发的焦点位置进行了原工艺的替代研究。经中性盐雾试验对比分析,优选了中性盐雾试验超过1000h的电镀锌镍合金工艺,并进一步进行了实际工况的模拟研究。电镀锌镍合金层经机械磨损、预置镀层缺陷的盐雾试验同样超过了1000h,说明在实际生产中,电镀锌镍合金能够满足多种复杂环境的防腐要求。通过跟踪使用电镀锌镍合金工艺的户外气体绝缘金属封闭开关设备2年,确认了电镀锌镍合金工艺的实际效果。
Outdoor gas insulated switchgear(GIS) need to have good corrosion resistance depending on the environment in which they are used. In this paper, the anticorrosion condition of ferrous metal parts of outdoor GIS is sorted out, and the original process alternative research is carried out on the focal position of corrosion. Through the comparison and analysis with neutral salt spray test, the electroplated zinc-nickel alloy process with neutral salt spray test for more than 1000 h is preferred, and the simulation of actual working conditions is further carried out. The salt spray test of the electroplated zinc-nickel alloy layer after mechanical wear and preset plating defects also exceeded 1000 h. It shows that in actual production, electroplated zinc-nickel alloy can meet the anti-corrosion requirements of many complicated environments. By tracking the outdoor GIS using the electroplated zinc-nickel alloy process for 2 years, the actual effect of the electroplated zinc-nickel alloy process was confirmed.
