摘要
阐述采用大段长高压电缆敷设方式能够减小故障率,提高供电系统的可靠性。单芯高压电缆金属护套感应电压受到电缆参数、排列方式、接地方式等多种因素的影响,从而影响到最大可敷设长度。基于ANSYS Maxwell 16.0仿真分析软件,选取110kV高压单芯电缆,对高压电缆在不同排列方式,以及交叉互联接地方式下的金属护套感应电压进行分析计算,证明当感应电压允许值为300V时,电缆敷设段长可获大幅提升。
This paper expounds that the laying mode of large section and long high-voltage cable can reduce the failure rate and improve the reliability of power supply system.The induced voltage of metal sheath of single core high voltage cable is affected by cable parameters,arrangement mode,grounding mode and other factors,which affects the maximum laying length.Based on ANSYS Maxwell 16.0 simulation analysis software,110 kV high-voltage single core cable is selected to analyze and calculate the induced voltage of metal sheath of high-voltage cable under different arrangement modes and cross interconnection grounding modes.It is proved that when the allowable value of induced voltage is 300 V,the length of cable laying section can be greatly improved.
