| 摘 要： | 对快速接地开关（ＨＳＧＳ）熄灭潜供电弧的机理进行了分析。采用ＨＳＧＳ后，弧道中的潜供电流和灭弧后的恢复电压，都有不同程度的降低，缩短了潜供电弧的燃烧时间，进而确保单相自动重合闸的成功。暂态网络分析仪（ＴＮＡ）实验和利用电磁暂态程序ＥＭＴＰ进行的仿真计算证明了上述论点。

| Abstract: | The mechanism of secondary arc extinction by high speed grounding switches (HSGS) is analyzed.The magnitude of the secondary arc current in arc path and that of recovery voltage is differectly reduced by HSGS,that in turn reduces the extinction time of the secondary arc and assures successful single pole autoreclosure. The approach is also verified by the transient network analyzer(TNA) test and the calculation of electro magnetic transient program(EMTP). |
