Abstract
The utility model discloses a gas-insulated type voltage transformer, comprising a barrel body which is internally provided with an iron core; the iron core are externally sheathed with a three-phase coil and a grounding coil in sequence; the outer side of the barrel body is provided with a secondary wiring flange; insulating gas is filled between the three-phase coil and the barrel body; the barrel body is provided with a ceramic tile sleeve which is internally provided with a conducting rod; and one end of the conducting rod is electrically connected with the three-phase coil, and the other end thereof is connected with a primary wiring flange. The gas-insulated type voltage transformer changes oil insulation into insulating gas insulation, solves the problem of medium loss when the oil insulation is adopted, is free of maintenance, is grounded at the neutral point by a zero-sequence transformer, and improves over-voltage resistance; in addition, the gas-insulated type voltage transformer changes the traditional single-phase structure into three-phase common body structure, has compact structure for the product and reduces the occupied area.
