1、畢業(yè)設(shè)計(jì)[論文]題目:220kv雙回路新型鋼管塔設(shè)計(jì)學(xué)院:電氣與信息工程學(xué)院專業(yè):電氣工程及其自動(dòng)化姓名:學(xué)號(hào):指導(dǎo)老師:完成時(shí)間:河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文)摘要河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文)摘要摘要隨著我國(guó)國(guó)民經(jīng)濟(jì)的持續(xù)發(fā)展,城市用電量每年遞增,城市用電負(fù)荷逐步增大,高壓輸電線路進(jìn)入城市已成為發(fā)展趨勢(shì)。因此,在城市建設(shè)的220kV高壓輸電線路將越來越多。由于電纜線路造價(jià)昂貴,我國(guó)目前還不能普遍采用,所以必然以架空線路為主,鋼管桿具有結(jié)構(gòu)簡(jiǎn)單、強(qiáng)度高、造型美觀、加工周期短、占地面積少、運(yùn)輸和安裝方便省時(shí)等優(yōu)點(diǎn),適用于多回路不同電壓等級(jí)同桿架設(shè),與現(xiàn)代化城市發(fā)展相協(xié)調(diào),被廣泛應(yīng)用
2、于10~220kV輸電線路的建設(shè)。根據(jù)架空線路導(dǎo)線截面大,多種電壓,多回路共桿,造價(jià)低的特點(diǎn)。與傳統(tǒng)的鋼筋混凝土電桿、角鋼塔相比可以知道鋼管桿具施工維護(hù)方便、強(qiáng)度高,為安全運(yùn)行提供了有力保證;并且也可以設(shè)計(jì)較高的鐵塔,以滿足跨越人行道、樹木的要求;易實(shí)現(xiàn)多回路,從而大大減少城市走廊的擁擠程度;不用打拉線,占地面積小,減少占用城市走廊;鋼管塔可以實(shí)現(xiàn)全鍍鋅,防銹性能大大提高同時(shí)也使鋼管桿造型美觀,與周圍環(huán)境比較協(xié)調(diào)的優(yōu)點(diǎn),本著重介紹設(shè)計(jì)?220kv雙回路新型鋼管塔設(shè)計(jì)。關(guān)鍵詞:高壓輸電線,角鋼塔,電力塔,雙回路,架空線路I河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文)AbstractABSTRACTA
