摘要

环网柜在与三芯电缆连接时其穿墙套管经常受到较大的作用力而受损

原因是电缆具有很大的抗弯刚度

其屈曲产生了较大的作用力于套管上。文中基于有限元分析建立了电缆芯线屈曲分析模型和电缆屈曲试验

探究了标准安装时、T型套管偏斜时和电缆芯线截取过长时3种情况下套管高度、套管间距、电缆型号和芯线弯曲形态对套管受力的影响规律

并提出合理建议来改善套管受力。为环网柜的设计和标准安装提供了理论依据。

Abstract

The wall bushing is often subjected to great force to be damaged or temperature rise when it connected with the three core cable. The reason is that the cable has large flexural rigidity

the force from cable buckling impact on the casing when the bushing connected to the split cable. In this paper

single-phase and three-phase model of cable cores is established based on finite element analysis

then the influence of case bushing height

bushing spacing

cable type and core wire bending shape on bushing stress are analyzed under the three kinds of conditions of standard installation

T type bushing deflection and cable core line intercept over-length. Last

cable buckling tests are designed to validate the result

the result shows that the error in a reasonable range. It provides a theoretical basis for the production design and standard installation of the ring main unit.
