| Abstract |
A underground electrical switch is a medium voltage switch used in the distribution network system for stable power supply. Until now, SF6 gas insulated switch has been mainly applied, but many researches are underway to expand and distribute eco-friendly gas insulated switch using dry-air instead of SF6 gas to reduce greenhouse gas. Design process for components such as insulation and shield parts in order to secure the optimized insulation performance of eco-friendly gas insulated switchgear was studied in this paper. An orthogonal table with S/N (Signal to Noise) ratio values was obtained using the Taguchi method and electric field analysis. In relation to the data of the orthogonal table, the combination of design element parameters corresponding to the optimal condition was obtained. Based on this methodology, the improvements in the optimized model are compared and analyzed. |
