본 발명은 가스절연개폐기 도체 절연코팅 끝단의 삼중점 전계 완화 구조에 관한 것으로서, 일단부 이상에 전기적 연결로드가 삽입되는 개구부가 마련된 중공 형상의 도체; 도체에서 개구부에 인접하여 위치하며, 라운드 형상이 마련된 전계 완화 홈부; 및 도체의 개구부의 외벽부와 내벽부를 감싸도록 배치되며, 전계 완화 홈부까지 연장되어 전계 완화 홈부의 일부를 감싸는 절연코팅부재를 포함하여 구성된다. 이러한 본 발명은 절연코팅을 도체에 부분적으로 적용하기 위하여 절연코팅 끝단의 삼중점 전계를 완화는 도체 형상 구조를 적용하여 절연 성능에 위험 요인을 제거하는 장점이 있다. The present invention relates to a triple-point electric field relaxation structure of a conductor insulation coating end of a gas-insulated switchgear, the triple-point electric field relaxation structure comprising: a hollow conductor having an opening part formed at one or more ends into which an electrical connection rod is inserted; an electric field relaxation groove part which is located adjacent to the opening part in the conductor and has a round shape; and an insulation coating member that is disposed so as to surround the outer wall portion and the inner wall portion of the opening part of the conductor, and that extends to the electric field relaxation groove part and surrounds a portion of the electric field relaxation groove part. The present invention has the advantage of removing a risk factor for insulation performance by applying a conductor-shaped structure for relaxing a triple-point electric field of an insulation coating end in order to partially apply an insulation coating to the conductor.
