Abstract

The invention provides a charge quantity measuring device which comprises an electrostatic simulation mechanism. The electrostatic simulation mechanism comprises a direct current high voltage power supply, an energy storage capacitor, a metal ball and an electrostatic conductive plastic sheet. The direct current high voltage power supply and the energy storage capacitor are connected in parallel. The positive pole of the energy storage capacitor is connected with the metal ball through a switch. The electrostatic conductive plastic sheet is adhered on the surface of the metal ball through an electrostatic conductive adhesive. The electrostatic simulation mechanism is provided with a sampling circuit and a measuring mechanism. The sampling circuit is connected in parallel with the measuring mechanism. The sampling circuit is composed of an input wire, a value set resistor and an output wire, wherein the input wire, the value set resistor and the output wire are connected in series. The measuring mechanism is a digital oscilloscope. Voltage waveforms in the sampling circuit during an electrostatic discharging process are measured by the measuring mechanism. The voltage waveforms are integrated. The quantity of charges, which flow to the ground during the process of electrostatic discharging to the ground, of an object is acquired.

Description

technical field [0001] The invention relates to the field of electrostatic measurement, in particular to a charge measurement device. Background technique [0002] In flammable and explosive places, human body static electricity is an important source of danger for fires and explosions. Grounding is one of the important ways to eliminate static electricity. Therefore, workers in flammable and explosive places must release human body static electricity in time. The main way to release static electricity from the human body is to use a human body static discharge device. An important indicator for evaluating the safety of the human body electrostatic discharge device is the amount of charge flowing to the ground during the process of the human body electrostatic discharge device discharging static electricity to the ground, which is called the amount of transferred charge, expressed by Δq. According to the law of electrostatic discharge, the larger Δq is, the greater the disc...
