摘要
利用数值分析,研究了SF_6断路器在无载开断条件下触头堵塞对灭弧室内气流场的影响,讨论了触头堵塞效应与介质强度恢复的关系。
Based on the numerical analysis, the interrupting process of gas-blast SF6 circuit breaker is emulated, and the effects of contact blockage with no-load on the gas flow field in the arc extinguish chamber and the recoery of dielectric strength are studied.
