Analysis of influencing factors and suppression methods of metal sheath circulation in high voltage single core cable
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.
