| 交流无间隙金属氧化物避雷器具有优异的非线性伏·安特性，响应特性好、无续流、通流容量大、残压低、抑制过电压能力强、耐污秽、抗老化、不受海拔约束、结构简单、无间隙、密封严、寿命长等特点。 AC gapless metal oxide arrester has excellent non-linear volt-ampere characteristics, good response characteristics, non-continuous current, large current capacity, low residual voltage, strong ability to suppress overvoltage, pollution resistance, anti-aging, not subject to altitude constraints, simple structure, no gaps, tight sealing, long service life and so on. 本避雷器在正常系统工作电压下，呈现高电阻状态，仅有微安级电流通过。在过电压大电流作用下它便呈现低电阻，从而限制了避雷器两端的残压 Under the normal operating voltage of the system, the arrester presents a high resistance state, and only the micro-ampere current passes through. Under the action of overvoltage and high current, the arrester exhibits low resistance, which limits the residual voltage at both ends of the arrester. |
