technical field [0001] The invention belongs to the technical field of electrostatic field detection, and in particular relates to an electrostatic field detection device adopting reverse electric field compensation technology. Background technique [0002] At present, the detection instrument that can continuously measure the electrostatic field is a mechanical electric field meter, which can detect small changes in the electrostatic field. The detection principle of this type of detection equipment is based on a mechanical electric field meter device that converts the value of the electrostatic field into a substitute signal through a continuously rotating motor, making it easier to measure. The disadvantage of using a rotating electric machine is that there are problems with mechanical failure and wear due to the use of moving parts.

The disadvantage of using a rotating motor is that there are problems with mechanical failure and wear due to the use of moving parts

[0003] In order to solve the above-mentioned technical problems, those skilled in the art use a micro-current amplifying circuit to detect the environmental electrostatic field. The existing technical problem of using a micro-current amplifying circuit to detect the environmental electrostatic field is that the leakage current phenomenon of electronic components cannot be truly detected. Avoid, so ordinary micro-current amplification circuits will have varying degrees of linear drift and distortion when measuring electrostatic fields, resulting in inaccurate measurement values
