Explosion-proof human body electrostatic discharger:
Explosion-proof human body electrostatic discharge device is a kind of human body electrostatic discharge product suitable for anti-static and other anti-static places. This product is mainly used to safely discharge the electrostatic charge of people to avoid human body electric shock or fire and explosion. occur. Compared with the general human body electrostatic discharge device, the explosion-proof human body electrostatic discharge device can reduce the venting time and greatly reduce the instantaneous electrostatic energy, so that in the process of human body static discharge, the shock can be effectively avoided or The occurrence of fire and explosion, etc., to protect the safe production of industry, is an indispensable part of modern enterprise safety management. Here, we take the FJDEx series of explosion-proof human body electrostatic discharger as an example to analyze the application of explosion-proof human body electrostatic discharge device in industrial electrostatic explosion-proof.
The working principle of the explosion-proof human body electrostatic discharge device.
In general, the explosion of human body static electricity requires four conditions at the same time. First, it must have the conditions for the generation of static electricity; secondly, it must have the level of static electricity accumulated in the human body and reach the discharge voltage; again, there must be a certain amount of explosive mixture; finally, the energy of the electrostatic discharge should reach the ignition point of the explosive mixture, only An explosion will occur only if all conditions are met. Under normal circumstances, the human body electrostatic voltage is between 1000V-10000V. According to the survey, if the human body's electrostatic voltage reaches 2000V, the discharge energy between the human body and the electrostatic conductor will reach 0.4mJ, which will cause explosion or fire.
Therefore, any human body electrostatic discharge device made of metal material does not have explosion-proof performance, and cannot be designed to safely release human body static electricity. The FJDEx series of explosion-proof human body electrostatic discharge device and human body contact parts are made of semiconductor composite material, which greatly prolongs the release time of static electricity in human body compared with human body electrostatic discharge device with metal conductor directly grounded and discharged. It makes up for the shortcomings of the general electrostatic discharge device, avoids the electric shock caused by the human body, thus greatly reducing the incidence of explosion fire, and can better meet the practical needs of modern industrial development.
