摘要
我国西部山区高铁具有线路坡度大、桥隧比高等明显特点,由此带来的变电所亭选址、供电单元划分及设备维护等方面难题均与27.5kV高压电缆安装方式密切相关。本文针对高桥、深路堑及隧道结构的不同特点,从设计方案合理性、施工难易程度及运营安全性方面着手,研究了山区高铁27.5kV高压电缆典型安装方式。
The high-speed railway in the western mountainous area of China has obvious characteristics such as high slope,high ratio of bridge and tunnel,and so on. The difficulties in locating substations,dividing power supply units,and the maintenance of equipment are all closely related to the installation schemes of 27. 5 kV HV cable.The typical installation schemes of 27. 5 kV HV cable for high-speed railway in mountains area was studied,according to the different characteristics of high bridge,deep cutting and tunnel structure,starting with the rationality of design scheme,construction difficulty and operation safety.
