The invention provides an improved 1000KV column capacitor type voltage transformer which comprises a capacitor voltage divider and an electromagnetic unit. The lower voltage end of the capacitor voltage divider is connected with the electromagnetic unit while the higher end is connected with a damping device. The damping device comprises a resistor and a power inductor that are connected in parallel. According to the embodiments of the invention, the technical solutions effectively inhibit high frequency voltage and current imposed on a capacitor voltage divider of a 1000KV column capacitor type voltage transformer and improves the insulation performance of the transformer. Further, the capacitor type voltage transformer is cost-effective to manufacture, and has an increased general sealing performance; the connection reliability of coupling capacitors is increased, and the overall design height of a damping device is effectively reduced.
