    Abstract: In order to solve the calculation of the temperature field of the multi-loop cable group, 220 kV high-voltage cable is taken as the research object, and a finite element method is used to establish a magnetic-thermal coupling calculation model of the multi-loop cable group. The electromagnetic loss and temperature distribution of the multi-loop cable group are calculated. Compared with the calculation results of the IEC 60287 standard, the validity of the model is verified. Combined with the simulation model, the effects of various factors such as air temperature and soil thermal resistance coefficient on the temperature field distribution of the multi-loop cable group are discussed, which provides a reference for the operation and maintenance of the cable group.
    Key words: high-voltage cables; multi-circuit; finite element method; steady temperature field; magnetic-thermal coupling
