The invention relates to a transformer bushing having a multi-screen structure, comprises an insulating tube body and a conductive rod, wherein the insulating tube body is divided into a multi-sectionstructure connected in ascending and descending order, two sections of the insulating tube bodies are connected through a flange, the lower end of the lowest section of the insulating tube body is connected with a grounding cylinder through a grounding flange, and at least three shielding covers are uniformly distributed between the conductive rod and the grounding cylinder; From the innermost shielding cover to the upper end of the penultimate shielding cover, the flange is connected from the top to the bottom, and the upper end of the outermost shielding cover is suspended. From the innermost shielding cover to the lower end of the penultimate second shielding cover, the lower end of the penultimate second shielding cover is connected with the grounding flange through the basin insulator, the lower end of the penultimate second shielding cover is connected with the grounding flange through the basin insulator. The lower end of the outermost shield is connected to the ground flange.By adopting the structure, the invention can uniformly electric field strength, meet the requirements of high voltage level partial discharge, improve the reliability of power network operation and prolong the service life of the product.
