Problems solved by technology

However, the existing test equipment can generally only perform one-dimensional electric field test calibration, and cannot continuously complete three-dimensional test calibration; the environmental parameters such as temperature, humidity, air pressure, and space charge inside the test equipment cannot be adjusted, and the temperature, humidity, air pressure, and Factors such as space charge affect the performance of the electric field sensor, so it is impossible to study, test and calibrate the performance of the electric field sensor in different application environments; it is impossible to conduct dynamic experiments on the space charge effect, and it is difficult to study the mechanism of the surface charge accumulation of the electric field sensor It is not conducive to the exploration of methods and technical approaches for anti-static interference and suppression of surface charge accumulation in electric field sensors

[0005] The current dynamic test and calibration device for electric field sensors is difficult to meet the experimental research and test calibration for the performance of electric field sensors in different application fields and application environments during the development of electric field sensors, and it cannot be used for new structures, new materials, and new packaging methods of electric field sensors. The experimental research and exploration of various physical problems involved restrict the development of high-performance new electric field sensors
