摘要

实验研究了电压下降时避雷针后阵真空灭弧击穿(延时击穿)的发生规律，并提出了其性质的假设。研究表明，真空灭弧器的击穿原因是绝缘壳内表面的高压放电。

Breakdowns of vacuum interrupters behind front of a lightning impulse

Laws of occurrence of breakdowns of vacuum interrupters behind front of a lightning impulse at recession of voltage (overdue delayed breakdowns) are experimentally investigated and the hypothesis of their nature is developed. It is shown, that the reason of breakdowns is the high-voltage discharge on an internal surface of insulating cases of vacuum interrupter.
