| 摘 要： | 建立了计算SF_6断路器灭弧室压力特性的数学模型。利用它对国产OFPI—220型SF_6断路器进行的计算结果表明,改变动触头排气孔位置及电弧对动触头内腔中气体的热效应可明显提高开断电流时灭弧室压力上升速度。

| Abstract: | Based on the calculations of the OFPI-220 circuit breaker a math model to compute the pressure characteristic in the arc-extinguishing chamber of the SF6 circuit breaker is derived. The results show that the position of the exhausting gas hole and the arc heat effects on the gas inside the hollow moving contact have obviously raised the pressure rising speed. |
