摘要
结合重载铁路27.5 kV电缆施工介入及运营管理实践,从设备管理单位的角度分析了27.5 kV电缆构造及运行特性,重点阐述了27.5 kV电缆金属屏蔽层接地方式及电缆敷设2项应关键卡控的施工项点,同时对运营管理中27.5 kV高压电缆应注意的问题进行了探讨。
With connection to the construction input and operational management practice for 27.5 kV cables for heavy haul railway,the paper analyzes the configuration and operation characteristics of 27.5 kV cables from the view of equipment managing department,illustrates with emphasis on the metal shield layer earthing mode for 27.5 kV cables and the two construction items which require critical control during laying of cables,and discusses at the same time the precautions required for operation and management of the high voltage cables.
