The invention discloses a voltage divider applied to a high voltage energy metering device. The voltage divider comprises a left polar plate (2), a right polar plate (3), a high voltage arm resistor (4), a low voltage arm resistor (11), a horizontal slide rail (7), a rotating bracket (5) and a strut (6). According to the invention, the distance between the left polar plate (2) and the right polar plate (3) can be adjusted; the rotating bracket (5) and the strut (6) form an isosceles triangular mechanism to ensure that lower and upper ends of the high voltage arm resistor (4) are always close to the left polar plate (2) and the right polar plate (3) in the moving process of the right polar plate (3); the gradient of electric field distribution between electrodes is always consistent with the gradient of voltage distribution on the high voltage arm resistor (4); the voltage divider can be adjusted according to the position of other components with large calorific value relative to the voltage divider; the influence of temperature on the linearly uniform distribution of potential is reduced; and the measurement accuracy is improved. The voltage divider provided by the invention can be used as the voltage divider of various high voltage metering devices.
