摘要
绝缘子式限压器作为一种新型配电线路防雷产品,在配网防雷工作中受到越来越广范的关注。对复合外套及瓷外套两种形式的绝缘子式限压器,在不同污秽条件下的电压分布进行了理论分析及试验验证。试验结果发现复合外套绝缘子式限压器在实际使用时,在无污秽和Ⅳ级污秽状态下,限压单元部分仅承受较小的系统电压,且数值稳定。而瓷外套绝缘子式限压器随着外套的污秽情况变化,其限压单元和串联间隙部分电压分布会发生明改变。
As a new lightning protection product for distribution lines,the insulator type voltage limiter has attracted more and more attention in the lightning protection work of distribution network. In this paper,the voltage distribution of two types of insulator type voltage limiter,polymer-housed insulator and porcelain-housed insulater,under the different pollution conditions is analyzed theoretically and verified experimentally. The test results show that in the actual use of the polymer-housed insulators,under the condition of no pollution and grade IV pollution,the limit voltage unit only bears the smaller system voltage,and the numerical value is stable. The voltage distribution of the voltage limiting unit and the series gap will change obviously with the change of the pollution condition of the porcelain-housed insulator.
