Gas-insulating electronic voltage transformer

The utility model relates to a gas-insulating electronic voltage transformer, which comprises a capacitive voltage divider, a shielding box and a signal acquirer. The capacitive voltage divider is arranged at the head of the gas-insulating electronic voltage transformer, the shielding box is disposed at a base arranged at the bottom of the gas-insulating electronic voltage transformer, a signal outlet end of the capacitive voltage divider is connected with a signal inlet end of the signal acquire by a shielding cable, and the capacitive voltage divider is a coaxial capacitive voltage divider. The gas-insulating electronic voltage transformer adopts the coaxial capacitive voltage divider as a primary and secondary voltage converter and uses SF6 (sulfur hexafluoride 6) gas for main insulation, an extremely thin flexible circuit board is arranged inside the coaxial capacitive voltage divider, a slightly uneven concentric electric field is formed by the flexible circuit board, which is attached to the inner wall of a metal barrel, and a primary conducting rod, the slightly uneven concentric electric field does not affect main wave transmission on the primary conducting rod or distort tested waveforms, the coaxial capacitive voltage divider is positioned at the head of the transformer, so that the structure is compact, and influence of inconsistent temperature is smaller.
