Abstract :
The 3-D substantial model is built for the bushing end of an ultra-high voltage transformer high-voltage coil and the surrounding of the equipotential shielding. This model is properly simplified according to the symmetrical structure of the coil. The electric field intensity nearby the transformer´s high-intense coil and the surrounding of the equipotential shielding are calculated on the basis of the finite element method. The distribution of the electric field is determined, and the maximum electric field intensity at top and bottom are 8.02×106 V/m and 6.67×106 V/m, respectively. The calculated results can provide basis for coil and equipotential shielding design of an ultra-high voltage transformer.
