The invention relates to a capacitance-resistance voltage-dividing type voltage transformer comprising a high-voltage electrode, of which an axis extends along an upward and downward direction. The inner side of the high-voltage electrode is provided with a low-voltage electrode. The inner side of the low-voltage electrode is provided with a grounding electrode coaxial with the high-voltage electrode. The grounding electrode, the low-voltage electrode and the high-voltage electrode are arranged in a coaxial mode from the interior to the exterior, so that the compactness of the structure of the product is facilitated, and moreover, distribution of electric fields is also facilitated.
