Abstract

The results of the reliability testing of Littelfuse and EPCOS gas-filled surge arresters for different overvoltages under DC discharge will be presented in this paper. The static breakdown voltage of these gas components was estimated using voltage increase rates ranging from 1 to 10 V/s. A detailed statistical analysis of experimental data has also been done. The delay time of these components for different nominal overvoltages has been investigated as an additional aspect important for component reliability. In addition, the delay time method was used as a statistical method which can give neither ion nor neutral active states number density in the glow and afterglow. It can be employed for qualitative observation of ions and neutral active states decay in the afterglow to such low concentrations where the other methods cannot be applied. Finally, a comparison has been done between the characteristics of two gas-filled surge arresters which have the same nominal overvoltage (Littelfuse and EPCOS) from different manufacturers.

不同类型避雷器在高过电压下击穿电压和延迟时间的演变

本文将介绍Littelfuse和EPCOS充气避雷器在直流放电下不同过电压下的可靠性测试结果。这些气体组分的静态击穿电压是用1到10 V/s的电压增长速率来估计的。并对实验数据进行了详细的统计分析。这些元件对不同标称过电压的延迟时间作为元件可靠性的另一个重要方面进行了研究。此外，延迟时间法作为一种统计方法，不能给出辉光和余辉中的离子和中性活性态数密度。它可以用于定性观察离子和中性活性态在余辉中衰减到如此低的浓度，而其他方法无法应用。最后，比较了不同厂家具有相同标称过电压的两种充气避雷器(Littelfuse和EPCOS)的特性。
