摘　　要：分析相地间隔棒的不同布置方式对特高压八分裂导线静态张力的影响,结果表明:安装相地间隔棒后整档导线张力显著增大;相地间隔棒在同一档导线中的不同布置方式对导线张力影响较大;安装相地间隔棒处,导线的张力有明显的跳跃现象;静载荷下相地间隔棒不会引起导线损伤。This paper analysed the influence of different configurations of phase-to-ground inter-spacer on the ultra high voltage eight bundled conductor static tension. Results showed that the tension of conductor between two towers was significantly increased with the installation of the phase-to-ground inter-spacer; it had a greater influence of different configurations of phase-to-ground inter-spacer on the conductor tension; on the conductor where installed phase-to-ground inter-spacer, the conductor tension had obvious jump phenomena; under static tension, phase-toground inter-spacer did not cause conductor damage.
