The fully enclosed feature of the GIS bus makes it impossible to directly measure the temperature of its internal conductor.To solve this problem

a GIS bus temperature deduction method based on finite element analysis is proposed

this method uses directly measurable GIS bus shell temperature

load current

ambient temperature and other parameters to derive conductor temperature.First

combined with GIS bus parameters

thermal parameters and boundary conditions

the COMSOL finite element analysis software is used to conduct electromagnetic-fluid-temperature field coupling simulation to solve the GIS bus temperature under different ambient temperature and load current conditions to obtain sample data.Finally

use sample data for training to establish a GIS bus temperature deduction model.The analysis results show that the temperature of the GIS bus conductor can be quickly obtained through the proposed temperature deduction method

which is of great significance for the safe operation of the GIS bus and the prevention of accidents.
