摘要
为了提升配网线路的绝缘水平,通过ATP-EMTP仿真软件,研究了10 kV配网系统中普通直线杆和终端杆线路分别混入复合材料直线杆及复合材料终端杆后,线路的绝缘水平及雷击闪络变化状况。研究结果表明,混合杆线路的耐雷水平比全普通杆线路的耐雷水平有较大提升,无论雷击点是否发生在复合材料杆上,闪络点都会发生在复合材料杆临近的普通杆或被击的普通杆上,突出了聚氨酯复合材料杆的绝缘优势,间接提升了该线路的耐雷水平。
In order to improve the insulation level of distribution network lines,this paper studies the insulation level and lightning flashover of ordinary straight pole and terminal pole lines mixed with composite material straight pole and composite material terminal pole respectively in 10 kV distribution network system through ATP-EMTP simulation software.The research results show that the lightning resistance level of the mixed pole line is much higher than that of the whole ordinary pole line.No matter whether the lightning point occurs on the composite pole or not,the flashover point will occur on the ordinary pole adjacent to the composite pole or the struck ordinary pole,which highlights the insulation advantage of the polyurethane composite pole and indirectly improves the lightning resistance level of the line.
