摘要
本文对SF_6断路器喷口耐电弧烧蚀性能进行了试验研究,拟合出喷口烧蚀与开断电流,燃弧时间和电弧能量的关系曲线,分析了开断电流和燃弧时间对喷口烧蚀的影响,试验结果表明国产喷口取代法国喷口是可行的。
The ablation endurance is investigated on SF6 circuit breaker nozzle, the relations between the ablation and interrupter parameters such as current, arcing time and arc energy are obtained. The influences from current and arcing tine on nozzle ablation are analysed in this paper.
