Abstract
On-board transformer is one of the important components in vehicle-mounted mobile substations for power supply. The features of electromagnetic vibrations of on-board transformer are closely related to the mechanical condition monitoring and the mechanical structure optimization. In this paper, the electromagnetic vibration of the OSFP11-120000/230 type on-board transformer is calculated with a 3D model through the finite element method. The magnetic flux density and electromagnetic forces of winding and core of on-board transformer are analyzed by a field circuit finite coupling element. Through the direct electromagnetic-structure coupling method, the winding vibration and core vibration of on-board are calculated. It is that the distribution of magnetostrictive force is basically similar to the magnetic flux of on-board transformer. The axial vibrations of transformer winding reach the largest at 1/4 and 3/4 positions with a main frequency spectrum of 100Hz. The radial vibration of transformer winding reaches the largest at the 1/2 position and the whole vibration strength is smaller than those of axial vibration. The core vibrations in each part are different with relatively rich frequency spectrum components.
