| 摘 要： | 本文讨论氧化锌避雷器在基波PT铁磁谐振过电压下的工作状况。基波铁磁谐振持续存在的范围首先被确定,然后将三种具有不同起始动作电压的氧化锌避雷器引入这一存在范围,以考察它们对基波谐振过电压的耐受性和抑制效果。一种估算避雷器能量的新算法也被提出,该算法能够采用有限步的数字模拟结果计算出避雷器在持续谐振过程中所吸收的能量。

| Abstract: | The working circumstances of metal- oxide arresters under fundamental frequency PT ferroresonance are discussed in this paper. The existence range is determinded for the sustained fundamental frequency PT ferroresonance. Three types of metal- oxide arresters with different reference voltages are applied to the existence range.Their tolerance and their suppressive effectiveness to the ferroresonant overvoltages are investigated respectively. A new algorithm is also presented, by which the energy absorbed by the arrester during the sustained ferroresonance can be estimated easily based on the computer simulation in limited time steps. |
