Inverted broadband voltage transformer

The invention provides an inverted broadband voltage transformer which is suitable for a power transmission line/high-voltage bus. The transformer comprises a measuring electrode (1), a shielding electrode (2) and a support rod (3), the shielding electrode (2) is in a hollow barrel shape, the measuring electrode (1) is fixed inside the shielding electrode (2) through the supporting rod (3), and the sum of the thickness of the measuring electrode (1) and the height of the supporting rod (3) is smaller than the height of the shielding electrode (2). The mutual inductor is used for realizing themeasurement of broadband voltage of the power electronic equipment based on respective stray capacitance to ground of the measuring electrode (1) and the shielding electrode (2), is high in environmental adaptability, and can realize the measurement of the broadband voltage; the voltage division ratio is stable, and the measurement precision is high; moreover, complex insulating and supporting structures are not needed, t
