Abstract

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.
