How much do you know about the principle of explosion-proof human body static eliminator
The human body static eliminator is mainly used to eliminate the static charge carried by the human body to avoid damage to the human body or objects. It is mostly used in industries, especially petrochemical, oil and gas, gas stations and other industries. These industries are prone to explosions due to static electricity. , Fire, etc., so there are special explosion-proof human body static eliminators.
When the electrostatic voltage of the human body reaches 2000V, the discharge energy between the human body and the electrostatic conductor can reach 0.4mJ, which is much higher than the ignition point of oil vapor 0.2mJ, which is very likely to cause a fire and explosion accident, so it must be discharged in time Discharge the static charge generated and accumulated by the human body. Touching the grounded metal is an effective way to eliminate static electricity. Therefore, there is a metal human body static eliminator, but touching a metal grounded human body static eliminator is an extremely fast process to eliminate static electricity. , Will cause current breakdown.
In order to improve this shortcoming, the explosion-proof human body static eliminator deliberately extends the static discharge time, thereby greatly reducing the instantaneous static energy, and also prevents the human body from causing a shock to the human body during the discharge of static electricity, and also avoids causing fire and explosion. The danger of accidents.
