交流輸(shu)電線(xian)(xian)路的電暈(yun)損失主要與導(dao)(dao)線(xian)(xian)表(biao)(biao)面場強和(he)天氣有(you)關，根(gen)據絕緣(yuan)水平要求確定了相間距(ju)離后，導(dao)(dao)線(xian)(xian)表(biao)(biao)面場強主要與導(dao)(dao)線(xian)(xian)分裂數、分裂間距(ju)和(he)子導(dao)(dao)線(xian)(xian)直徑有(you)關，分裂數越(yue)多，子導(dao)(dao)線(xian)(xian)直徑越(yue)大，表(biao)(biao)面場強越(yue)小(xiao)。擴(kuo)徑導(dao)(dao)線(xian)(xian)通過(guo)支撐鋁線(xian)(xian)疏繞(rao)的方式(shi)擴(kuo)大了導(dao)(dao)線(xian)(xian)外(wai)徑，這樣可減小(xiao)...

  分(fen)(fen)裂(lie)導(dao)(dao)(dao)(dao)線(xian)是由三根或四根單(dan)芯導(dao)(dao)(dao)(dao)線(xian)經過某種(zhong)工藝制造在(zai)一起的一種(zhong)可分(fen)(fen)裂(lie)的導(dao)(dao)(dao)(dao)線(xian),或者稱導(dao)(dao)(dao)(dao)線(xian)束,這種(zhong)分(fen)(fen)裂(lie)導(dao)(dao)(dao)(dao)線(xian)不僅(jin)僅(jin)是形(xing)式上與常規導(dao)(dao)(dao)(dao)線(xian)不同(tong)(tong),由于分(fen)(fen)裂(lie)導(dao)(dao)(dao)(dao)線(xian)可使導(dao)(dao)(dao)(dao)線(xian)周圍磁場(chang)分(fen)(fen)布改變,從而等效地增(zeng)大了導(dao)(dao)(dao)(dao)線(xian)半徑,減(jian)小(xiao)了導(dao)(dao)(dao)(dao)線(xian)電抗；同(tong)(tong)...
