High-voltage static voltage measurement device

The invention provides a high-voltage static voltage measurement device which comprises an induction pole plate, a partial voltage capacitor and a measuring circuit. The output of the induction pole plate is divided into two branch circuits, one branch circuit is grounded through the partial voltage capacitor, and the other branch circuit is connected with the measuring circuit; the measuring circuit comprises a low-bias input amplifier, an in-phase proportional amplifier, a low-pass filter, a measurement display module, an equipotential shielding ring, a follower amplifier and a switch; an input pin on the low-bias input amplifier is surrounded by the equipotential shielding ring; each output branch circuit of the induction pole plate is connected with the low-bias input amplifier, the in-phase proportional amplifier, the low-pass filter and the measurement display module in sequence through the switch; the reverse input end of the low-bias input amplifier is connected with the input end of the follower amplifier, and the output end of the follower amplifier is connected with the equipotential shielding ring. The high-voltage static voltage measurement device can well solve the electric leakage problem of electric charges in the high-voltage static voltage measurement process.
