摘要
根据城市轨道交通直流电缆的特性、具体结构和参数,按照传输直流和交流电能的不同特点,分别建立了电缆连续载流量的数学模型,对主要的城市轨道交通直流电缆品种及规格进行计算,分析电缆载流量影响因素,并对直流和交流传输下的载流量进行对比,以期对城市轨道交通直流电缆的选型提供有效参考。
Based on the characteriati,structure and parameters of DC cable for urban rail transit,a mathematic model has been set up for the cable to calculate the current rating of cables,according to the difference between DC and AC transmissions,The varieties and specifications of the main cables are also calculated,the influencing factors to the current rating of cables are analyzed,the ampacities of DC and AC transmissions are contrasted here. it is a reference to the selection of DC cable for urban rail transit.
