| 摘 要： | 500 k V伊穆直流输电系统接地极线路导线发生绝缘子炸裂、导线落地事故,由于接地极线路招弧角放电间隙过小,导致直流系统在操作过电压作用下产生燃弧现象。直流系统无法熄弧是造成事故的主要原因,对此提出了加大招弧角放电间隙、调整接地极线路绝缘配置等防范措施。 |
| 关 键 词： | 直流输电系统 接地极线路导线 燃弧 招弧角 放电间隙 绝缘配置 |

| Abstract: | According to the 500 kV Gimo HVDC ground electrode insulator, conductor ground crack fault, analysis of grounding line arcing horn discharge gap which was too small in the operating over voltage under the effect of arc, DC system couldn＇t extinguish the arc, which was the main cause of the ground wire insulator crack, then put forward preventive measures to increase the arcing horn discharge gap, adjusting the ends of the earth line insulation configuration and other means. |
| Keywords: | DC transmission system grounding line conductor arcing trick arc angle discharge gap insulation configuration |
