Description

technical field [0001] The invention relates to the technical field of high-voltage electronic circuits, in particular to an explosive static electricity tester for simulating human static spark discharge. Background technique [0002] Since explosives are mostly highly insulating substances, high-energy static electricity is easily generated and accumulated during production, transportation and use. When electrostatic discharge (ESD) occurs, the danger of ignition of explosives is extremely high. According to statistics, about 10%-20% of accidental explosive explosion accidents are caused by electrostatic discharge. Therefore, enough attention must be paid to the electrostatic safety in the production of explosives. The electrostatic sensitivity of explosives is an important index to evaluate the safety performance of explosives. It refers to the sensitivity of the tested sample to electrostatic discharge under certain conditions and under the action of a certain electrost...

Problems solved by technology

However, the current commonly used JGY-50 explosive electrostatic spark sensitivity instrument has a capacitor energy storage voltage range of 0-30kV. Obviously, this instrument does not meet the requirements for testing the electrostatic sensitivity of explosives to human electrostatic spark discharge.

And the explosive electrostatic tester that can fully simulate the static spark discharge of the human body has not been reported yet.
