| 接觸網(wǎng)導(dǎo)線斷線分析及改進(jìn)措施(38 卷) |
| 英文標(biāo)題 |
| Causes of Broken Contact Wire of Catenary and the Improvement Measures |
| 摘要 |
| 依據(jù)TB/T 2809—2005《電氣化鐵道用銅及銅合金接觸線》，對合武線接觸網(wǎng)斷線進(jìn)行常規(guī)項目試驗，含氧量、含錫量測試，以及斷口金相組織分析，認(rèn)為接觸導(dǎo)線受到較大拉力和卡緊力是接觸網(wǎng)導(dǎo)線斷裂的根本原因，通過試驗驗證了結(jié)論的可靠性，并提出相應(yīng)改進(jìn)措施。 |
