摘要
笔者对用于青藏工程直流场电容器的关键技术问题进行分析研究,研究了高海拔的绝缘修正问题,验证了高海拔地区低气压对电容器外壳变形的影响,分析了高海拔对电容器局部放电的影响,研究解决了小容量直流滤波电容器的内熔丝问题,通过试验研究确定了电容器的表面抗风沙油漆。
In this article, combining with the special requirements of DC project, the key technical problems of the DC filter capacitors for the project is studied and analyzed. The high altitude insulation coordination problems are studied; the deformation of the capacitor case under the depression of high altitude is verified; the influence on the partial discharge of the capacitor under high altitude is analyzed; the problems of the internal fuse of small capacity DC filter capacitor are studied and solved; through the experimental study, the paint which has the resistance on sand blown by wind is determined.
