摘要
采用计算机仿真计算与试验相结合的方法对500 kV紧凑型线路用复合相间间隔棒力学性能进行了分析研究,理论计算和试验结果表明:理论计算与试验结果基本吻合,复合相间间隔棒具有稳定的后屈曲性能,并且对于500 kV紧凑型输电线路选择芯棒直径为30 mm的相间复合相间间隔棒是合适的;通过对该复合相间间隔棒用0.1%NaCl水溶液浸泡48 h后进行陡波试验研究,结果表明,复合相间间隔棒的电气绝缘性能也是可靠的。
The mechanical properties of phase-to-phase composite spacer on 500 kV compact line were studied by means of computer simulation and experimental methods in this paper.The results show that the theoretical calculation results are consistent with the experimental ones.The composite spacer has a stable post-buckling performance and the composite spacers with core diameter of 30 mm,are appropriate for the 500 kV compact transmission line.Steep front impulse voltage test was carried out on composite spacer after immersing in 0.1% NaCl solution for 48 h.The results show that the electrical insulation performance of composite spacer is reliable.
