高速鐵路用銅合金接觸網(wǎng)導(dǎo)線及銅扁線的產(chǎn)業(yè)化研究摘要

高速鐵路交流供電系統(tǒng)的核心是接觸網(wǎng)導(dǎo)線。傳統(tǒng)接觸網(wǎng)導(dǎo)線使用的是鍍鋅鋼絲，但由于鋼絲疲勞壽命短且易受環(huán)境影響，不能完全滿足高速鐵路對接觸網(wǎng)導(dǎo)線的要求。本文研究了銅合金接觸網(wǎng)導(dǎo)線及銅扁線在高速鐵路中的應(yīng)用。通過實(shí)驗(yàn)研究和現(xiàn)場測試，證明銅合金接觸網(wǎng)導(dǎo)線及銅扁線具有良好的導(dǎo)電性能和抗腐蝕性能，在高速鐵路中具有廣泛應(yīng)用前景。研究表明，銅合金接觸網(wǎng)導(dǎo)線的通過度和抗風(fēng)振性能優(yōu)于鍍鋅鋼絲，銅扁線的導(dǎo)電性能優(yōu)于銅圓線。研究結(jié)果為銅合金接觸網(wǎng)導(dǎo)線及銅扁線的產(chǎn)業(yè)化生產(chǎn)提供了理論依據(jù)和技術(shù)支持。
