Why is it effective to continuously touch the human body electrostatic discharger?
Human body electrostatic dischargers are generally installed at the door of chemical warehouses and other places where flammable and explosive materials are stored. Before entering, you must touch the black sphere on the top with your palm until the alarm no longer sounds, then you can enter. But people often find that - every time the alarm stops, the alarm will sound again after a period of time after the palm is removed and then touched again.
This is not actually a problem with the human body electrostatic discharger, but it just shows that it is in normal operation. The human body itself will generate static electricity. The function of the human body electrostatic discharger is to ensure that the voltage of the body is safe when people enter inflammable and explosive places. level, does not mean that the human body no longer has static electricity.
