摘要

电缆作为高效、高可靠性的输电、供电方式

随着其应用范围的扩大

在实际运行中存在的问题也越发突出。文中就高速铁路牵引电流在电缆金属护套中产生的感应电压进行了分析计算

首先介绍了接触网计算理论

包括静电感应电压计算、电磁感应电压计算以及耦合感应电压计算。其次利用CDEGS软件对牵引电流在电力贯通电缆金属护套中产生的感应电压进行了仿真分析。最后根据计算结果说明在进行高速铁路电力贯通电缆线路设计、维护时

应充分考虑牵引电流对电力贯通电缆的影响

并采取措施把危害降低到最低程度。

Abstract

With the wide application of cable

which is an efficient and highly reliable method of power transmission and power supply mode

the problems in actual operation is also more prominent.In this paper

the induced voltage generated in the metal sheath of the cable by the traction current of high-speed railway is analyzed and calculated.Firstly

the calculation theory of contact network is introduced

including the calculation of electrostatic induced voltage

electromagnetic induced voltage and coupled induced voltage.Secondly

the CDEGS software is used to simulate and analyze the induced voltage generated by the traction current in the metal sheath of the power through cable.Finally

it is stated in accordance with the calculation results that in case of design and maintenance of highspeed railway power through cable lines

the influence of the traction current on power through cables shall be fully considered and measures shall be taken to minimize the harm as much as possible.
