| Abstract: |
| 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. |
