The working principle and characteristics of electrostatic discharge ball
The human body static discharge alarm is an instrument suitable for flammable, explosive and anti-static places. It is characterized by a reasonable design of human body electrostatic discharge resistance, reasonable and effective control of human body electrostatic discharge, prolonging human body electrostatic discharge time, reducing the instantaneous human body electrostatic discharge energy, and enabling human body static electricity to be safely discharged. At the same time, it can detect whether the human body is in reliable contact with the electrostatic touch ball, and the sound and light alarm prompts whether the static electricity is completely eliminated.
The device used to discharge the static electricity of the human body is usually placed before performing some static-sensitive equipment operations, and touch this thing to eliminate the human body from being charged. The principle is very simple, the static electricity is eliminated, they are all discharged to the ground, in order not to make the human body feel tingling when the static electricity is discharged [The tingling is because there is a relatively large current flowing through the body, although the time is short, but the current There are dozens of amps or even hundreds of them. The conductor ball and the ground are connected by a large resistance. At this time, the current amplitude is limited, so that it is safe to discharge and it is not the human body to understand the current.
