Influence of Plateau Environment on Performance of Electric and Electronic Products of Roiling-stock

The authors introduce the characteristics of plateau environment and the altitude-based classification of electric and electronic products used on rolling stock. The paper focuses on the influence of altitude on insulation performance, temperature rise of those products and the corresponding methods used for modification, the measure that should taken in high altitude localities to deal with thunder, lightening and pollution. The authors also discuss the influence of high altitude on arc quenching performan...
