低壓配電網(wǎng)接線方式

發(fā)布日期:2022-04-17 點擊率:111

  配電系統(tǒng)的接線形式與高壓配電系統(tǒng)基本相同。

  低壓配電網(wǎng)接線主要形式:放射式、樹干式、混合式、鏈式。

  1.放射式接線:主干線由變電所低壓側(cè)引出,接至主配電箱;再以支干線引到分配電箱或用電設(shè)備上;以支線接至用戶或其它設(shè)備。

  2.樹干式接線:配電方式簡單,電氣設(shè)備少。但靈活性差,檢修維護不方便!

  3.混合式接線:樹干式與放射式的混合。變壓器低壓側(cè)出線經(jīng)過低壓斷路器將干線引入某一供電區(qū),然后由支線引至用電設(shè)備。采用較多!

  4.鏈式接線:只用于相互之間距離很近,容量又很小的用電設(shè)備。可靠性差,在鏈中任何地方發(fā)生故障都會影響全鏈設(shè)備。
