Abstract

In order to realize the quantitative calculation of large section cable’s thermal stress and thermal strain, the finite element calculation model of cable’s magnetic thermal mechanical coupling field is established, which takes a large cross-section cable fixed with hoops at both ends as a modeling object. The electromagnetic losses of cable are calculated, which are loaded on the finite element model as the excitation to calculate thermal stress and thermal strain of large section cable. Results show that thermal stress of large section cable is mainly distributed on the conductor and the metal sheath, but thermal stress of the other layers of cable is smaller. The relationship expression between thermal stress of the conductor and the metal sheath and load current is proposed by the method of data fitting, which provides a theoretical reference for formulating the scientific operation strategy of large section cable.
