The thermal field Analysis of GIS bus bar and its Application in the Temperature on-line monitoring
In light of an 110KV indoor GIS substation of certain power supply company,two kinds of three-dimensional solid model (straight Tube-Shaped and T-Shaped) of the GIS bus-bar cylinder are established.The magnetic field,eddy current field of the established GIS bus-bar model is calculated under different conditions such as symmetry currents,asymmetric currents based on ANSYS/EMAG.By the simulation,we get the magnetic intensity distribution of the GIS bus-bar,the eddy current distribution of the GIS bus tube distribution and the power losses on different situations.According to the calculation result of the power losses,the SF6 fluid,temperature field of the GIS bus-bar is analyzed and calculated by the FLUID142 element of ANSYS.In order to verify the accuracy of the calculation results,the simulation of the GIS tube temperature is compared with the actual temperature measured during the GIS operation under different situations according the simulation.The simulation results are proved to have a good agreement with the measured data..
