Problems solved by technology

However, there are still defects in the application of ZPD-1 and EST405 in the operation process of dangerous goods with high potential electrostatic hazards.
For example, during the manual handling of dangerous goods, and during the transportation of railways, highways, ships, etc., due to various vibrations and friction, static electricity is easy to accumulate to a dangerous high level, and there are reports of spontaneous combustion accidents on the way of transportation vehicles. , How high is the static electricity accumulated in the above operation process, what is the polarity, due to the limitation of cost and technical implementation, it is still impossible to realize the real-time monitoring of the whole process; in addition, both ZPD-1 and EST405 are passive real-time measurements on the site. Failure to give advance warning of a hazardous situation

Description

technical field [0001] The invention relates to the technical field of electrostatic testing, in particular to an electrostatic dynamic potential measuring device. Background technique [0002] Electrostatic discharge (ESD for short) refers to the phenomenon that when the field strength around the charged body exceeds the insulation breakdown field strength of the surrounding medium, the electrostatic charge on the charged body partially or completely disappears due to the ionization of the medium. The internal cause depends on the conductivity of the substance, and the volume resistivity is at 10 11 ~10 15 Substances in the range of Ω.cm are most likely to generate static electricity; external causes are various, such as friction between objects, electric field induction, medium polarization, and adhesion of charged particles, etc. [0003] The faults and hazards caused by ESD are commonly known as electrostatic disasters. Compared with convention...
