中文摘要:
      目的 电气设备铜材因遭受含硫化氢环境腐蚀的影响,致使其性能下降,并给电气设备的安全运行埋下安全隐患。为保证电气设备在现场服役环境中的安全可靠性,需对铜材在该环境中的寿命进行预测。方法 利用失重法研究电气设备用铜材在现场环境和室内外硫化氢加速环境下的腐蚀动力学规律,通过灰色关联度分析方法探讨两种环境条件下的关联性,并建立铜材在现场服役环境中的寿命预测模型。结果 在现场和室内硫化氢环境下,铜材腐蚀动力规律遵循幂函数定律;两种环境的灰色关联系数为0.72,相关性良好;铜材的腐蚀寿命模型为T现场=0.74T加速2.16。结论 利用室内硫化氢加速腐蚀试验可以对电气设备用铜材在现场环境中的腐蚀状态和腐蚀寿命进行预测。
英文摘要:
      The corrosive effects on copper of electrical equipment in the hydrogen sulfide environment may lead to the performance degradation of electrical equipment and cause hidden danger for the safe operation of electrical equipment. The work aims to predict the life of copper in the hydrogen sulfide environment to ensure the safety and reliability of electrical equipment working in field service. The corrosion kinetics of copper for electrical equipment in field environment and outdoor hydrogen sulfide environment was investigated by weight loss measurement. The correlation of two environments was studied with Grey correlation method, and the life prediction model of copper in field service was established. The corrosion kinetics of copper in field and hydrogen sulfide environments followed power function law. The gray correlation of two environments was 0.72, so the correlation was good. The corrosion life model of copper was T field = 0.74Tacceleration2.16. The indoor hydrogen sulfide accelerated corrosion test can be used to predict the corrosion status and the corrosion life of copper for electrical equipment in the field service environment.
