10 kV地下电缆出变电站后与配网衔接方案研究

Research on Connection Schemes for 10 kV Underground Cable Between Main Grid and Distribution Network

摘要:
目的为了避免10 kV地下电缆在主网与配网交界面受边坡影响造成电缆连接不畅的情况。
方法针对南方电网常用的1.2 m×1.2 m电缆沟，设定明确的对比原则，通过多方案分析及对比。
结果制定出一套适用于不同地形及支护条件下的10 kV地下电缆出变电站后与配网衔接的解决方案。
结论该解决方案使配网工程的电缆能通过电缆沟顺畅地接驳进入变电站，解决了10 kV地下电缆在主网与配网交界面连接不畅的问题。该方案可在标准化工作中加以固化形成标准设计方案中的一部分。

Abstract:
Introduction In order to avoid poor connection of 10 kV underground cable between main grid and distribution network because of the influence of slope.
Method Aiming at the 1.2 m × 1.2 m cable trench commonly used in the South China Power Grid， this article set a clear principle of comparison， and through analysis and comparison of various schemes.
Result A set of solution schemes were formulated for different topography and supporting conditions.
Conclusion The solution schemes enables the cable of distribution network project to connect smoothly into substation through cable trench， and solves the problem of poor connection between the main grid and distribution network of 10 kV underground cable.This schemes can be solidified in the standardization work to form part of the standard design scheme.
