摘要
文章通过对干式电流互感器设计原理、产品结构、高海拔环境运行特点的分析,从设备的外绝缘、合成绝缘材料的抗紫外线老化、大温差环境下的密封、局部放电、运行中介损超标等方面突出问题进行了深入的阐述,得出了该类型产品适合在高海拔环境下运行的结论,并建议在海拔3500 m以上应谨慎使用。
The paper analyzes the dry- type current transformer's design principle, product structure and the operation features on high altitude, expounds the equipment's external insulation, synthesis- insulating material's anti - ultraviolet ageing, seal on large temperature difference environment, abnormal tan on operation etc. problems. It enduces the conclusion that the product fits operation on high altitude, and should be carefully utilized.
