摘　　要：我国变电站电缆具有分布广、易燃等特点,发生燃烧或绝缘损坏,严重时可能引发极其严重的后果,造成财产损失。基于此,对变电站电缆防火分隔技术进行研究,对目前变电站电缆防火分隔方案进行总结和整理,并在此基础上提出2种新型变电站电缆防火分隔方案,经过综合评估,确定最优分隔方案。所设计的分隔方案能够为变电站电缆防火技术提供参考。The cables of substations have the characteristics of wide distribution and flammability.The burning or insulation damage of substation cables may cause serious consequences including property losses.Therefore this paper focuses on the fire-proof separation technology of substation cables,summarizes and clarifies the currently adopted fire-proof separation schemes,and proposes two new types of fire-proof separation schemes for substations.The better scheme is determined through comprehensive estimation,and the proposed schemes may contain useful information for relevant practices.
