SF6 가스절연 스페이서의 접지부 전계 완화에 대한 실험연구

A Experimental Study to Control Local Electric Field Intensification at Grounded Part of the Spacer in SF6 Gas Insulating System

This study is to develope a spacer having almost uniform field distribution along the profile by controlling the high electric field in tensification at earthed part, especially triple junction in the spacer-electrode-gas boundary interface. Based on the extensive field calculation using CSM, a model spacer has been manufactured and tested. The test results show that the breakdown strength of the spacer is almost same as that of SF6 gas itself without spacer.
