摘要

在架空输电线路上

绝缘子能够将杆塔和带电导线隔离开来

因此

使绝缘子保持良好的绝缘强度有助于提高输电可靠性。但是

随着电网雷击概率的不断增大和各类污染的日益严重

绝缘子闪络事故仍是严重威胁电网安全稳定运行的因素之一。为杜绝绝缘子闪络事故

课题组在前人研究基础上

研制出一种带有主动灭弧装置的新型招弧角。通过大量试验证明

该新型招弧角对工频续流电弧抑制作用极强

即便空气间隙中流经巨大短路电流

新型招弧角也能将其可靠熄灭

确保绝缘子不因闪络而损坏。

Abstract

I ncreasing probability of lightning strike and serious pollution induce more insulator flashovers to harm the safety and stable operation of power systems.To prevent insulator flashover accident

our research group developed a new type of arcing horn with an active arc-extinguishing device.A large number of tests show that the arcing horn can significantly restrain power frequency current to reliably extinguish arc for protecting insulators from damage due to flashover even if short circuit current flows through the air gap.
