초록

초고압 GIS에서 도체를 지지하고 가스구획을 담당하고 있는 삼상일괄형 에폭시 절연 베리어의 최적형상을 얻기 위한 연구와 분석이 진행되어지고 있다. 초고압 GIS는 전력계통에서 상당한 신뢰성을 유지해야하는 제품이다. 본 논문에서는 GIS 베리어의 전기적인 절연성능과 기계적인 강도를 동시에 향상 시키면서 소형화 경량화가 될 수 있는 최적 형상의 베리어를 구하고자 하였으며, 주재료인 에폭시 소재와 충진 재료인 필러의 혼합비율을 변경함에 따라 SIO2의 초고압 분야의 적용 타당성 검토를 확인하고자 하였다.

Some insulating materials are organized and analyzed with variables to obtain the optimized profile of Some insulating materials are organized and analyzed with variables to obtain the optimized profile of encapsulated three phase of epoxy barrier which is applied to gas compartment and supporting conductors for high voltage GIS (gas insulated switchgear). The high voltage GIS is used in electrical power system and operating reliability. In this paper, optimization possibility of barrier shape including both electrical insulation performance and mechanical strength, premised on that condition minimizing volume and light weight should be kept for high voltage GIS, could be achieved by analysis simulation. As a result, filling material which is lower permittivity such as SiO2 instead of Al2O3 properly to the epoxy material, can be improved to increase the electrical insulation performance and mechanical strength for an optimized profile barrier of a high voltage GIS.three phase of epoxy barrier which is applied to gas compartment and supporting conductors for high voltage GIS (gas insulated switchgear).
