1、摘 要10kv贯通线是电气化铁道十分重要的组成部分，它担负着向铁道沿途的车站信号、通信、电气集中连锁、照明、检修设备等供电的责任，因此确保它的安全运行，对整条电气化铁道的安全运行有着十分重要的意义。铁道供电属于高压电范畴，供电线路及设施始终伴随铁道延伸，设备多、里程长，地理和气候环境影响大，工作条件恶劣。根据铁道部有关规程的规定：变配电所、自闭线、贯通线等供电设施，是重要的行车装备。铁道供电的负荷属于一级负荷，如果发生供电中断，将导致铁道运输秩序混乱或运输中断，甚至发生运输设备损坏、人身伤亡事故，造成重大的经济损失和社会影响。因此为了保证铁道运输
2、的安全正点，要求铁道电网的供电必须安全可靠。所以电气化铁道电力供电必须为铁道行车的装置和设施提供质量合格的电能，保证不间断的可靠供电。本文从10kv贯通线施工设计的特点出发，结合当前电气化铁路贯通线施工设计的新材料、新工艺、新技术完成了贯通线的施工设计，其整个设计能够满足各项要求。关键词：电气化铁路；贯通线；施工设计Abstract10kvlineiselectrifiedrailwaythroughaveryimportantpartofitbearsalongthewaytotherailroadstationsignals,communica
