Gaoya dianqi, 2012 在实际应用中,电压互感器二次回路中性点除规程要求的在控制室一点接地外,常另在开关场经氧化锌阀片接地。笔者就一起阀片击穿形成CVT二次侧两点接地造成的保护不正确动作事故出发,经波形分析得出氧化锌阀片被击穿,造成两点接地,保护装置将接受到不正确的电压量,从而导致保护的误动或拒动的结论,并提出了消除该项隐患的建议。

Dianci bileiqi, 1988 日本富士公司发展了一种氧化锌阀片,其中的添加剂用氧化镨代替氧化铋。显微结构中没有引入锑而形成的尖晶石,呈现二相结构。这种结构提高了阀片的有效截面,使伏安特性、通流能力及寿命得以提高。硼掺杂使阀片边缘晶粒减小,使边缘电流密度减小 ...
