世界最长最高电压等级输电工程顺利跨越黄河

2017-12-27


  昌吉—古泉±1100千(qian)伏特高压(ya)直(zhi)流输电(dian)(dian)工(gong)程西起新疆(jiang)准东(dong)昌吉换(huan)流站(zhan),东(dong)到安徽(hui)淮南(nan)古泉换(huan)流站(zhan),途经新疆(jiang)、甘肃(su)(su)、宁夏、陕(shan)西、河南(nan)、安徽(hui)六省区,线路(lu)全(quan)长(zhang)3319.3公(gong)里,其中甘肃(su)(su)段(duan)全(quan)长(zhang)1264公(gong)里,占线路(lu)总长(zhang)三分之一(yi)以(yi)上。据国家电(dian)(dian)网甘肃(su)(su)省电(dian)(dian)力(li)公(gong)司(si)介绍,这是目前(qian)世界上输电(dian)(dian)距离最(zui)(zui)长(zhang)、输电(dian)(dian)量(liang)最(zui)(zui)大、电(dian)(dian)压(ya)等级最(zui)(zui)高的(de)输电(dian)(dian)工(gong)程。

  国家电网(wang)甘(gan)肃省电力公司建设(she)部高级工程师(shi)吕旭东介绍(shao),跨(kua)越(yue)黄河(he)施工地(di)(di)位于黄土高坡(po)地(di)(di)形区,生态环境(jing)脆弱,加(jia)上受河(he)谷地(di)(di)形影响,经常(chang)会遭(zao)遇河(he)谷阵(zhen)风,对搭建铁塔(ta)、牵(qian)引导线等工程进(jin)展都造成(cheng)很大的(de)不利影响。

  为(wei)了减(jian)少输(shu)电线(xian)对途经地(di)区造(zao)成的噪音、占地(di)影响,该工程还在局部走(zou)(zou)廊(lang)紧张路段将铁塔设计较(jiao)一般输(shu)电铁塔高出20多米,并将导线(xian)由(you)传统(tong)的平(ping)行走(zou)(zou)线(xian)改为(wei)垂直走(zou)(zou)线(xian),以此来节省空(kong)间,远离村庄。
