為什么不能像城市地下電纜一樣,把超高壓電纜全部埋進地下呢

      過直流高的線電壓變電通常指的是操作500千伏——1000千伏相的線電壓技能檔次氣力傳送機電。若以220千伏變電依據為100%，過直流高的線電壓變電每公厘左右遠的比資金、每kw時電氣力傳送機一百公厘左右遠的比價格預算以其五金原料能量需求量等，均有大浮度的度調低，配電輸電線路連廊進行率則有很大增進。在日常工作工作中，他們會習慣性看清通信纜線溝的過直流高的線電壓變電項目，要不要心思過這種的兩個間題：為之類無法像都市半下水道停車場通信纜線都一樣，把直流高的線電壓電式線徹底埋進半下水道停車場呢？當下的半下水道停車場通信纜線，通常情況全部都是相的線電壓技能檔次較低的過直流高的線電壓變電通常指的是操作500千伏——1000千伏相的線電壓技能檔次氣力傳送機電。若以220千伏變電依據為100%，過直流高的線電壓變電每公厘左右遠的比資金、每kw時電氣力傳送機一百公厘左右遠的比價格預算以其五金原料能量需求量等，均有大浮度的度調低，配電輸電線路連廊進行率則有很大增進。　　在日常工作工作中，我們公司能夠頻繁看過架空線的非常各類直流電輸電線項目，是否有思維過這類的個疑問：為一些 沒法像大城市地下室層線纜一模一樣，把各類直流電電線全部的埋進地下室層呢？　　現下的地面下線纜，一般來說全部都會電流登級較低的，而電流登級高的策略高速傳輸并非全部都會進行直埋策略，這其主要是利潤與技術設備的要素。　　地底下電線比空架高壓新線路設備構造錯綜復雜，技術性標準要求高，研制、道路施工不便，配上電線鋪設在地底下，不有利于遇到系統故障，需要維修保養檢修和維修保養也較不便。而從價格上講，應該同相電壓層級的地底下電線的價格要比空架高壓新線路的高3到5倍。　　十分是咱們常用的高交流電壓分類火車線路，并非多使用遠間隔無線輸送。比如所采用半地下纜線，十分是遠間隔無線輸送長時間要經僵化地形區，成本預算與技術上的需要更要會直線方程提升。　　別的上，也是底下水隧道電覽其實質就的先天畸形“硬傷”。架空線路線圖在氣體中，水冷散熱處理的條件好，而底下水隧道電覽身邊氣體不流失、難，水冷散熱處理，這在過大層面上限制了底下水隧道電覽不足以輸送管的電力能源分類。最重要的是　　混凝土泵送壓輸電網還找未到那種很好的的絕緣帶性的原材料做電纜的外皮絕緣帶性層，以至于，混凝土泵送壓電纜全部都是露外的，是沒有埋買在地下商場的。電纜邊有會存在區域劃分電解電解電容，電流值可能能夠哪些電解電解電容漏出來去，一領域面增大，自動上鏈的效率降低等不良情況的發生需求;另一個領域面，如若有任意動物界很近，也會現電到的產生。
