配电型支柱式复合外套氧化锌避雷器运行经验

Operation Experience of Zinc Oxide Surge Arrester Used in Distribution as Post Insulator

分析配电型支柱式复合外套无间隙氧化锌避雷器(MOA)技术性能和运行状况 ,认为该类型避雷器不仅能可靠地耐受弧光接地过电压、PT谐振过电压及各种操作过电压 ,有效地限制异常操作过电压 。

A new type polymeric housed zine oxide surge arrester had been designed and operated several years ago. The operation experiences of this type MOA, such as anti arc grounding over voltage, anti lightning impulse over voltage and effectively restricting various switching over voltage were emphasized in this paper. It is not only used as surge arrester, but also used as post insulator.
