摘要

电力电缆固定金具安装在电缆线路上

是对电缆起固定和支撑作用的重要附件设备

而目前工程中对于大截面电力电缆固定金具的选型仍缺乏相关规范。文中通过建立大截面电力电缆与固定金具的三维有限元涡流场模型

仿真计算出不同固定金具参数下金具的涡流损耗值

并以仿真数据为基准分析了电缆固定金具参数与涡流损耗之间的数值关系。通过曲线拟合、非线性回归分析以及误差校验得出固定金具涡流损耗与金具厚度、长度、气隙大小以及金具材料电导率之间的计算公式。为实际工程中电力电缆固定金具的安装提供了参考

对电力电缆固定金具的设计和选型具有一定的指导意义

可供电缆固定金具生产和研究的应用。

Abstract

To provide a selection basis for the metal cleat of large cross-section power cable

a three-dimensional finite element model of eddy current field is built for large cross-section power cable and metal cleat. Simulation is performed with the model to calculate the eddy current loss of cleat with different cleat parameters. And the numerical relationship between cleat parameters and eddy current loss is analyzed based on the simulation data. By fitting curve

nonlinear regression analysis and error checking

a formula of cleat’s eddy current loss versus cleat’s thickness

length

size of air gap

and conductivity is deduced. This research may provide a reference for design

manufacture

selection

and installation of metal cleat of power cable.
