Abstract:
The methods and results of the modeling of explosions and the kinetics of the stress-strain state of high-voltage, oil-filled electrical equipment are presented on the example of the destruction of high-voltage, oil-filled transformers in the event of a short circuit. The theory, methods, and developed modules in the Flow Vision and Gas Dynamic Tool (GDT) packages and the pairing of the ANSYS and LS DYNA packages are described. The physical and mathematical models underlying the developed approaches, computational schemes, and packet interfaces are described. A comparison with the experimental results is made.
