摘要三相导线垂直排列布置方式的500kV紧凑型输电线路杆塔空气间隙的放电特性较传统紧凑型线路有很大的不同,有必要通过试验对其空气间隙距离进行校核。本文首先分析了500kV垂直排列紧凑型线路塔头的初步设计依据,然后开展了模拟塔头的冲击放电特性试验及带电作业操作冲击放电试验研究。结果表明按传统500kV紧凑型线路的绝缘配合原则初步设计的垂直排列紧凑型线路杆塔的空气间隙距离可以满足安全可靠性要求。文章最后给出了带电作业时应保持的头顶-上横担和头顶-上方导线最小安全距离。研究成果可为500kV垂直排列紧凑型线路工程的设计提供参考,为相关人员带电作业的安全提供保证。

Abstract：For 500kV vertically aligned compacttypetransmission linestowers,theairgapdischarge characteristicsare very different withtraditional compact lines, therefore, it is necessary to check its air gap distancebytest.In this paper, firstly, basis for the preliminary design of 500kVvertically aligned compact tower head is analyzed, and then, on simulation tower head, test research ofimpulse discharge characteristics and switching impulse discharge for live working is carried out. Results show that theair gap distance of 500kV vertically aligned compacttype transmission linestowers, which is selected according to traditional compact lines insulation coordination principle, is reliable. At last, the paper recommended the live working minimum safety distance of head to cross arm and head to the aboveconductor. Results can supply reference for the design and ensure the safety of live working of relevant personnel.
