Outdoor single-phase compound insulation grounded voltage transformer

An outdoor single-phase compound insulation grounded voltage transformer comprises a voltage transformer body, an insulating shell, a silicone rubber jacket, a secondary terminal chamber and groove-shaped bases. The voltage transformer body comprises a wound iron core, a low voltage secondary coil, a high voltage primary coil and a high voltage conducting rod, wherein the high voltage primary coil and the low voltage primary coil are of a concentric cylinder structure, the high voltage primary coil is located outside the low voltage secondary coil, and the high voltage conducting rod is provided with a high voltage electric field grading ring. The silicone rubber jacket is combined with the outer surface of the insulating shell in an insulated bonding mode, and five big umbrella skirts and four small umbrella skirts are arranged on the upper portion of the silicone rubber jacket. Four big umbrella skirts are arranged on the lower portion of the silicone rubber jacket. The outdoor single-phase compound insulat
