Títol:: 3D thermal model and experimental validation of a low voltage three-phase busduct
Tema:: Busbar Trunking System (BTS); Busway; Busduct; 3D Thermal modelling; Numerical simulation; Experimental validation
Descripció:: The thermal behavior of an industrial Low Voltage non-segregated three-phase busduct was analyzed by means of the comparison of a 3D numerical model with experimental results. This model has been carried out using COMSOL Multiphysics, software based on finite element method. The numerical model replicates the short-circuit test, using the same geometry configuration and the boundary conditions of the laboratory in which this assay was carried out. The standard IEC 61439 was applied, both in test and model, in order to obtain the steady state temperatures in several parts of the busbar system. As a result of the data comparison can be concluded that the experimental test was replicated by the numerical model with sufficient accuracy. The temperature differences between simulation results and those of the heating tests were in a narrow range. On the other hand, a sensitivity analysis was carried out with the intention to study the influence of sensors positioning on the temperature measurement in the laboratory test, thus concluding no high precision was needed in the location of the temperature meters. As a final conclusion of this study, it is needed to point out that the numerical model has the enough exactness to be used in the first steps of the busbar design.; The authors of this research wish to acknowledge to the Spanish Ministry of Science for the financial support to the National Research Project: Performance of the insulating systems in transformers: alternative dielectrics. thermal-fluid modelling and post-mortem analysis (DPI2013-43897-P).
