摘要:
近年来,蒙东地区110 kV输电线路常由于鸟害而发生跳闸故障,其中鸟粪闪络是引起鸟害跳闸故障的主要原因。为探究鸟粪滴落通道对闪络的影响,本文通过自主设计试验平台,模拟了110 kV线路复合绝缘子鸟闪试验,试验利用鸟粪模拟液研究了不同鸟粪滴落通道下鸟粪电导率、粘度、均压环、对鸟闪概率的影响,试验发现电导率越大、粘度越高,鸟闪概率越严重,加装均压环会加剧闪络概率; 鸟粪通道与导线共面时闪络最严重,异面时闪络概率最小。目前防鸟罩、大盘径伞群等盘径设计多由异面闪络试验得出,其防护效果还有待进一步改善提高。
Abstract:
In recent years, 110 kV transmission lines in east Inner Mongolia area often have tripping faults due to bird damage. Among them, bird dropping caused flashover is the main cause of bird faults. In this paper, the bird-caused flashover test of 110 kV line composite insulator was simulated by self-designed test platform. The effect of bird manure conductivity, viscosity, pressure equalization ring on bird-caused flashover probability was studied by using bird droppings simulation fluid in different bird droppings position. The higher the rate and the higher the viscosity, the more serious the bird's flash probability. The addition of the equalizing ring will aggravate the probability of flashover. When the bird dropping channel is coplanar with the wire, the flashover is the most serious, and the probability of flashover is the smallest when the surface is different. At present, the design of the diameter of the anti-bird cover and the large-diameter umbrella group insulator is mostly determined by the different surface flashover test, and the protection effect needs to be further improved.
