Abstract
This study presents the calculation method for short-circuit electrodynamic force of power transformer winding and development of electrodynamic force analysis software package. Finite element method is used to achieve the leakage magnetic field of transformer winding under short circuit operation. Electromagnetic force is calculated by using Lorentz force formula. Based on mechanical properties of kraft-manila paper and press-board, which are used as insulation and reinforcement materials, considering the elastic force and friction of the various insulating materials, the equivalent mass spring model of winding is established and axial dynamic force and displacement is calculated. Using client/server mode, short-circuit electrodynamic force analysis software for power transformer winding is developed, which consists of several sub-system, such as parameter input and calculation and result analysis. The client/server structure facilitates the expansion of the software features. This software package has been applied in the power transformer manufacture enterprise.
