交流海底电缆载流量影响因素分析

Analysis of Influencing Factors of AC Submarine Cable Carrier Flow

本文根据工程设计的敷设方式和500 kV海底电缆的结构参数,核算了交流海底电缆登陆段载流量,并针对登陆段采用的沟道直埋敷设方式,计算分析了环境温度、敷设深度、土壤热阻系数等典型的环境参数取值对登陆段载流量的影响.计算结果可以为载流量提升方案提供技术依据.

According to the laying mode of engineering design and the structural parameters of 500 kV true submarine cable,the carrying capacity of AC submarine cable landing section is calculated,and the influence of typical environmental parameters such as ambient temperature,laying depth and soil thermal resistance coefficient on the carrying capacity of landing section is calculated and analyzed according to the directly buried channel laying mode adopted in landing section.The calculation results can provide technical basis for the scheme of carrying capacity lifting.
