Claims (6)
- 유황을 수용하는 양극용기와, 나트륨을 수용하는 음극용기, 양극용기와 음극용기 사이에 설치되고 나트륨 이온만을 선택적으로 이동시키는 전해질관, 음극용기와 양극용기 사이를 절연시키는 절연체, 상기 음극용기를 감싸 전해질관과 음극용기 사이에 설치되며 전해질관과 음극용기 사이를 선택적으로 차단하는 안전관을 포함하고, 상기 안전관은 외주면에 원주방향을 따라 돌출된 적어도 하나의 돌출부를 포함하며,
상기 안전관은 상단이 절연체 상부의 금속칼라까지 연장되고, 상기 돌출부는 상기 금속칼라를 향하여 안전관 상단에 형성된 구조의 나트륨 유황 전지. - 제 1 항에 있어서,
상기 돌출부는 안전관의 길이방향을 따라 복수개가 간격을 두고 배치된 구조의 나트륨 유황 전지. - 제 1 항 또는 제 2 항에 있어서,
상기 돌출부는 원호형태로 만곡형성된 구조의 나트륨 유황 전지. - 제 3 항에 있어서,
상기 돌출부는 안전관에 일체로 형성된 나트륨 유황 전지. - 삭제
- 제 1 항에 있어서,
상기 돌출부는 안전관 외주면에 설치되는 금속링으로 이루어진 나트륨 유황 전지.
