摘　　要：随着社会经济飞速发展,人们用电需求持续增长,使得同一隧道中的电缆输电线路不断增加,各线路之间相互影响,导致金属护套环流问题日益严重。一旦出现环流,不仅会影响电缆运行安全,而且可能会造成严重的电力事故,因此研究高压单芯电缆金属护套环流影响因素及有效的抑制方法具有重要的现实意义。分析了高压单芯电缆金属护套环流的产生机理及影响因素,提出有效抑制电缆金属护套环流的方法,以期为相关行业工作人员提供参考和借鉴。With the rapid development of the social economy,the demand for electricity continues to grow.As a result,the num-ber of cable transmission lines in the same tunnel is increasing,leading to interactions between the lines.This interaction has re-sulted in increasingly serious issues with metal sheath circulating currents.Once these currents occur,they not only affect the safety of cable operations but may also result in serious power accidents.Therefore,studying the influencing factors of metal sheath circulating currents in high-voltage single-core cables and developing effective suppression methods is of significant practi-cal importance.Based on this,the article analyzes the generation mechanism of metal sheath circulating currents in high-voltage single-core cables,identifies the factors affecting these currents,and proposes methods to effectively suppress them,in order to provide references for professionals in the relevant industry.
