    Abstract: In the application of Gas-Insulated Switchgear (GIS) in the power system, there are lots of problems such as difficult detection of heat loss, high current density, and large eddy current loss. Therefore, in this study, the electromagnetic and temperature field distribution characteristics of GIS are explored and their distribution rules are revealed through the multi-physics field coupling simulation of electromagnet-flow-thermal fields. At the same time, the influence of light radiation, rated current and ambient temperature on GIS temperature distribution is analyzed. The simulation results show that in the cross section of GIS, the temperature distribution is bilaterally symmetrical, and the upper part is higher than the lower part; light radiation has a significant effect on the temperature rise of GIS; the value of the operating current has the greatest influence on the temperature rise of GIS; the effect of external ambient temperature on GIS temperature rise is not obvious.
    Key words: gas-insulated switchgear; electromagnetic distribution; temperature distribution; influencing factor
