摘　　要：对宿迁闻涛220 kV变电站半地下电缆层内电缆敷设方式及电缆层层高确定过程进行了分析,通过对半地下电缆层功能分区及一、二次电缆吊支架优化布置,提出了一种同时满足电缆防火分区、电缆层巡检无死角、逃生通道畅通需求的新型半地下电缆层设计方案。该方案在宿迁闻涛220 kV变电站顺利实施,效果显著,为后续实施的220 kV变电站半地下电缆层方案设计提供了借鉴。This paper analyzes the cable laying method and the process of determining height of semi underground cable layer in the Wentao 220 kV substation in Suqian.By optimizing functional zoning of the semi underground cable layer and layout of the primary and secondary cable suspension brackets,a new semi underground cable layer design scheme that meets the requirements of cable fire zoning,non-dead corner cable layer inspection,and smooth escape routes,is proposed.This scheme has been successfully implemented in the Wentao 220 kV substation in Suqian,achieving significant utility and is helpful in subsequent implementation of the semi underground cable layer design of 220 kV substation.
