110千伏SF6全封闭组合电器中的SF6磁吹避雷器研制成功

Gaoya dianqi, 1972
西安高压电器研究所和西安高压电瓷研究所共同合作研制成功了一种供110千伏SF6全封闭组合电器用的SF6磁吹避雷器。这种避雷器的特点是本体放在一个充有一个表压的SF6气体的密闭的金属容器内。本体由串联间隙、阀片和保证串联间隙电压分布均匀的电阻、电容组合而成。单个火花间隙的灭弧电压为6千伏,主间隙由一对铜钨电极组成 ...

空气断路器領域內的最新成就

Gaoya dianqi, 1959
近年來,不論在国内外,空氣断路器已趋向于大容量。本报导將介紹BBC决速空气断路器的最新型式。在以压縮生氣作为灭弧介质的断路器中,主要有下列提高断流能力的措施:提高压力、增大噴嘴和氣管(包括貯气筒)的截面积、串联灭弧室(在使用控制电容器使电压均匀分布的情况下),应用小的有效电阻来減衰振盪 ...
