以城市建设区域变电站为核心的综合管廊方案探讨

Discussion on the Scheme of Utility Tunnel Centered Round the Substation in Municipal Construction Zone

城市建设区域变电站高压电力电缆进出线数量众多,传统敷设方式对土地空间利用、城市景观及交通影响较大,高压电力管线入廊是影响综合管廊技术方案的重要因素,需因地制宜确定变电站周边综合管廊系统布局。通过对某市含变电站建设区域内周边电力通道方位进行梳理,分析高压电力电缆入廊条件,提出了一种满足具体条件下变电站进出线通道入廊的综合管廊系统布置及高压电力舱节点方案,反馈优化早期的电力规划以分散电力通道潮流,借助BIM技术合理确定节点尺寸,为变电站高压电缆入廊提供技术思路和方法建议。

High voltage electric in and out cables of the municipal construction zone substation are numerous.Land development,city landscape and traffic trip are affected by traditional cable routing.High voltage electric cable into utility tunnel is the important factor which affects utility tunnel scheme.The utility tunnel should coordinate with local conditions.Hackling the electric in and out cables channel of one city zone substation,analyzing the condition of high voltage electric cable into tunnel,a utility tunnel layout system and high voltage electric cabin joint scheme was proposed to meet the requirement of substation high voltage electric cables into utility tunnel,the existing electric planning was approved to disperse electric channel flow.The joint size was determined reasonably by BIM,which could provide technical approaches and advises for substation high voltage cable into utility tunnel.
