Abstract

High-voltage power cable design has always been an important part of power design.With the improvement of the power grid construction

the problem of eddy current loss in cable trenches leading to wasted electrical energy and influencing cable life becomes more and more serious

therefore

in order to reduce the eddy current loss of the metal pipe trench

a new cable trench design is proposed.For the three-phase multi-circuit metal pipe cable trench

through analysis and research

it is found that the main factors affecting the eddy current loss

including cable phase arrangement

pipe thickness and cable distance.Through Ansoft Maxwell’s simulation test

the eddy current loss of the top tube is simulated under different conditions of cable phase arrangement

top tube thickness

and cable distance.Then

the cable trench structure is optimized using the finite element method to obtain a new cable trench design.Tests have shown that the design can effectively reduce eddy current losses.
