Abstract

This paper represents the results of study on Extra High Voltage Power Cable Connection System Development. The purpose is to evaluate structural safety by numerical analysis for the relaxation of electric field concentration and by structural analysis of Carrier Pipe for easy installation of High Insulating Rubber Sleeve in the field, which is core technique of connection system. According to the results, the thickness of Carrier Pipe needs at least 9mm by optimization analysis of deformation behavior and insulating design & relaxation of electric field concentration. The result of contraction behavior of the connection part can be demonstrated with the same result of electric field relaxation analysis at the boundary of the electrode inserted into the insulating rubber sleeve.

본 논문은 초고압 전력케이블의 접속재 개발을 위한 연구결과로써, 접속시스템의 핵심기술인 고절연 고무슬리브의 현장 접속 작업의 용이성을 위한 Carrier Pipe의 구조해석과 주요부의 전기적 특성과 전계의 집중을 완화하기 위한 수치해석 등을 실시하여 구조적 안정성을 평가하려 한다. 절연설계 및 전계완화 해석에 의한 검증과 접속재의 수축거동 해석에 의한 Carrier Pipe의 최적화된 형상으로 두께가 최소 9mm이상을 갖는 Carrier Pipe가 필요하며, 전기적 전계완화 해석결과 고절연 고무슬리브의 중앙매립전극 경계면으로써, 접속재 수축거동 해석 결과와도 일치함을 검증할 수 있었다.
