A graded type voltage transformer

The invention relates to a graded type voltage transformer comprising an inner insulation dielectric layer and an external insulation dielectric layer which are arranged in a coaxial mode; the interior surface of the inner insulation dielectric layer is bonded with a first metal layer; the external surface of the insulation dielectric layer is bonded with a second metal layer; the interior surface of the external insulation dielectric layer is bonded with a third metal layer positioned on the outer side of the second metal layer; the external surface of the external insulation dielectric layer is bonded with a fourth metal layer; the second metal layer comprises at least one inner side low-voltage electrode; the third metal layer comprises an outer side low-voltage electrode which is the same with the inner side low-voltage electrode in terms of quantity; and the inner side low-voltage electrode is in short circuit with the outer side low-voltage electrode. According to the invention, problems that a continuous arranged structure of a metal layer, an insulation dielectric layer, a metal layer, an insulation dielectric layer and a metal layer has relatively high requirements for processing technology in the prior art are solved.
