Insulation grounding shielding device

The invention belongs to the technical field of transformer manufacturing, and particularly relates to an insulation grounding shielding device which can be applied to a high-frequency converter transformer. Comprising an insulating ground screen, an upper end electrostatic ring and a lower end electrostatic ring, the upper end electrostatic ring and the lower end electrostatic ring are arranged at the upper end and the lower end of the periphery of the insulating ground screen in a sleeving mode, the insulating ground screen is installed between a network side winding and a valve side winding of the converter transformer, and an insulating end ring C is fixedly installed below the lower end electrostatic ring. An insulating end ring B is fixedly installed below the upper end electrostatic ring, and an insulating end ring A is fixedly installed above the upper end electrostatic ring. The upper end electrostatic ring and the lower end electrostatic ring comprise insulating rings, the section of each insulating
