(1)电源屏至送电端轨道变压器I次侧的电缆允许压降为30V。
计算干线供电的电缆芯线时,每段轨道道路所需电流应分别按下列给出值考虑:电化区段 0.10A;非电化区段 0.14A,电缆电阻为23.5欧/km。主要在非电码化区段考虑,电码化区段送电端均要发码,没有送电电缆合用现象,一根送电电缆最长为L=30/(23.5*2*0.1)=6.38km。非电码化区段有送电电缆合用时,计算公式为:30=23.5*2*(N1*L1*0.1+N2*L2*0.1+……)注:N为每段所含区段数,L为每段长度,去线回线均考虑电阻,所以乘以2,Nx一般为送电合用径路上的最远送电端。
(2)受电端轨道变压器至继电器室的电缆电阻应不大于150欧。
单拉公式:L=150欧/(23.5欧/km *2)=3.19km(即受电端去、回线均单拉时能满足的最大长度)。
