Abstract In order to achieve timely diagnosis of overheating faults of gas insulated bus bars (GIB), this paper established a GIB temperature rise thermal network model including contact structure based on thermoelectric analogy and heat transfer theory. The contact thermal resistances between the finger, the conductive rod and the substrate were calculated by the disk- contact single heat flow channel model (CMY model), and the nonlinear convective heat transfer resistance and the radiant heat transfer resistance of GIB were obtained by finite element numerical simulation. The physical tests of steady-state temperature rise of GIB under different test currents were carried out. The results show that: under different test currents, the calculation speed of thermal network method is about 34 times that of finite element method, the maximum temperature error between the calculated and measured values is 9.5%, and the minimum is 0.2%, which verifies the thermal network model of GIB. This model can be used to quickly estimate the finger and shell temperature of GIB, providing an effective analysis method for GIB thermal design and temperature rise monitoring.
