750kV交流金属氧化物避雷器均压环结构对避雷器电位分布的影响研究

Dianci bileiqi, 2015
750 kV交流系统用复合外套无间隙金属氧化物避雷器在杂散电容的影响下电阻片轴向电位分布极不均匀,承担电压负荷过高的电阻片会加速劣化、导致避雷器损坏;通常采用在避雷器高压端安装均压环的方式改善其电位分布。采用有限元计算方法,对避雷器采用不同罩入深度、环径、管径的均压环时的电位分布补偿效果进行了研究,分析了电阻片的最大荷电率和沿避雷器电阻片轴向的电位分布,得到优化的750 kV交流金属氧化物避雷器的均压环结构参数,并总结了结构参数对避雷器电位分布的影响,为避雷器均压环的设计提供了参考依据。

用于防护陡波头过电压的阀片

Dianci bileiqi, 1991
为了保护电器和电机的线圈免受陡波过电压的危害,采用由多个氧化锌阀片组装成的阀体。但是由于众所周知的原因（寄生电容的存在、表面污秽）,沿阀片电压分布是很不均匀的,使阀片慢慢地转入导电状态和降低其可靠性。提出了在由n个阀片组成的阀体上从高压端起n—1个阀片用电容器并接 ...
