Research of the Method to Generate Steep Impulse Current on 10～35kV Arrester

对10~35kV整只避雷器进行陡波冲击残压试验不仅可以避免避雷器陡波残压中感性压降计算的问题、客观反应其残压水平,同时也可以为用户抽检试验更全面的考核提供直接试验条件。分析了产生10~35 kV整只避雷器陡波冲击电流的回路结构和参数特点,并且采用冲击电压发生器调试出了10~35 kV避雷器标称电流下的陡波冲击电流,为10~35 kV避雷器陡波冲击残压试验的进行奠定了基础。

The steep impulse current residual voltage performed on 10 ~ 35kV complete arrester is not only a good way to reflect the residual voltage which is not necessary to calculate the inductive voltage drop,but also provides a test condition for the more comprehensive assessment for user sample test. Analyses has been made about the test circuit structure and parameters for generating steep impulse current on10 ~ 35kV arrester. The impulse voltage generator is adopted to generate the nominal steep impulse current on 10 ~ 35kV arrester,which is the basement for steep impulse current residual voltage test on10 ~ 35kV arrester.
