摘要
介绍500kV紧凑型拉V塔.其三相导线采用等腰倒三角形排列方式,并组装手杆塔塔窗之中,打破了传统的杆塔相间有接地构架的结构形式,使杆塔和线路十分紧凑,达到了降低线路综合造价之目的.重点介绍了国内首次进行的相间绝缘子串及线路相间操作冲击叠加放电特性试验和相间边缘子串的电压分布测量,并将所得结果与国外试验结果进行了比较.为我国进一步开展大功率紧凑型输电线路的研究和设计提供了经验和基础数据.
500kV compact guyed V tower, thrce phases conductor arrangcd in invcrt-les triangle and installed among the tower winndow, is presented. It has been changed that traditional tower Structure form cxisti grounding pole-body between phase and phase, to make the tower and line very compact. Therefor, the aim of rcduced line comprehensive price is achived. The switching impulse flashovcr test on the inaulator strings and bctwccn phase and phase, voltage distrubition mcasurcmcnt of thc phase to phase insulators strings are introduced cmphatically. The obtained results related to line phase-to-phase insulation is first timc in out country. The experience and cssential data is provided for further dcvclopment of high natural power compact transmission line in the future.
