1、I摘要隨著社會(huì)和經(jīng)濟(jì)技術(shù)的發(fā)展，電氣化鐵路的發(fā)展也越來越迅速。我國(guó)對(duì)能夠適用于電氣化鐵路的接觸網(wǎng)也提出了相關(guān)的要求。本設(shè)計(jì)的目的是完成嘉峪關(guān)車站接觸網(wǎng)平面設(shè)計(jì)，同時(shí)按要求繪制接觸網(wǎng)設(shè)備裝配圖和平面圖。首先對(duì)設(shè)計(jì)地區(qū)的氣象條件資料進(jìn)行收集，根據(jù)鐵路目標(biāo)速度對(duì)線索材料進(jìn)行了選擇，再確定其懸掛類型。根據(jù)氣象條件及線索材料計(jì)算負(fù)載。其次，根據(jù)最大受風(fēng)偏移計(jì)算得到最大跨距；根據(jù)規(guī)程規(guī)定的錨段長(zhǎng)度選擇錨段，使其張力差要滿足要求。然后，對(duì)硬橫跨進(jìn)行分

2、析選擇。考慮到接觸網(wǎng)將來可能的改進(jìn)及預(yù)留，根據(jù)計(jì)算結(jié)果對(duì)接觸網(wǎng)進(jìn)行了相應(yīng)的調(diào)整，以使本設(shè)計(jì)滿足電氣化鐵路的技術(shù)要求。最后在上述原理的基礎(chǔ)上，對(duì)嘉峪關(guān)車站接觸網(wǎng)進(jìn)行CAD平面設(shè)計(jì)，并對(duì)具有代表性的支柱進(jìn)行了容量的校驗(yàn)計(jì)算。在接觸網(wǎng)平面圖的表格欄里對(duì)地質(zhì)情況、支柱類型、安裝圖號(hào)、側(cè)面限界等進(jìn)行相應(yīng)的說明。本論文以接觸網(wǎng)的基本技術(shù)原理為核心，以實(shí)際線路狀況為依據(jù)，對(duì)嘉峪關(guān)車站的接觸網(wǎng)布置進(jìn)行了平面設(shè)計(jì)，基本滿足電氣化鐵路的技術(shù)要求。關(guān)鍵詞：接
