Hybrid insulators that have the advantages of both porcelain (high mechanical strength and chemical stability) as well as polymer (light weight and high resistance to pollution) insulators, can be used in place of individual porcelain and polymer insulators that are used for both mechanical support as well as electrical insulation of overhead power transmission lines. The most significant feature of hybrid insulators is the presence of porcelain/polymer interfaces where the porcelain and polymer are physically bonded. Individual porcelain and polymer insulators do not have such porcelain/polymer interfaces. Although the interface is expected to affect the mechanical/electrical properties of the hybrid insulator, systematic studies of the adhesion properties at the porcelain/polymer interface and the effect of the interface on the insulation characteristics and electric field distribution of the hybrid insulator have not been reported. In this study, we fabricated small hybrid insulator specimens with various types of interfaces and investigated the effect of the porcelain/polymer interface on the microstructure, insulating characteristics, and electric field distribution of the hybrid insulators. It was observed that the porcelain/polymer interface of the hybrid insulator does not have a significant effect on the insulating characteristics and electric field distribution, and the hybrid insulator can exhibit electrical insulating properties that are similar or superior to those of individual porcelain and polymer insulators.

본 논문에서는 2회선 지중송전선로(관로)의 회선별 부하량에 따른 최적의 상배치 도출을 위한 수치해석을 진행하였다. 수치해석을 위해 선로의 매설 심도, 상간 거리는 고정하였고, 케이블 시스 및 접지는 고려하지 않은 상태에서 2회선의 부하 크기를 각각 변화시켰을 때 계산되는 자계값 저감이 가장 큰 상배치를 도출하였다. 계산 결과 전류의 크기와 상관없이 2회선이 ㄴ-ㄱ구조로 배열될 경우 CBA-ABC의 역상배열이 ABC-ABC의 기본 배열 대비 약 83%의 저감을 보였다. 향후 2회선 이상의 다회선에 대한 최적 상배치, 조류 방향, 회선별 전류값이 상이할 경우 등에 대한 추가적인 해석이 필요하다.
