摘要
研究了不同浪涌电流条件下继电器电寿命试验过程中的闭合燃弧时间变化规律,分析了闭合燃弧时间与操作次数之间的关系,指出在通断操作过程中每次的燃弧时间值具有随机性,随操作次数的增加,燃弧时间没有表现出明显的变化规律,可能逐渐延长也可能逐渐缩短,或者出现反复波动。
The experiment was carried out to understand how the operation cycle affect the make arc duration in the electrical endurance test under the different surge current con- ditions. It is showed that the arcing duration is with the characteristic of randomness in each operation and does not have definite correlation with the operation cycle, and can get higher or lower or fluctuated in the test period.
