Application of human body electrostatic discharge ball
In the working environment of many flammable and explosive hazardous areas and anti-static places, a small amount of static electricity can cause great damage, so how do we choose some effective equipment to safely discharge the electrostatic charge accumulated by the human body itself To avoid fire and explosion accidents caused by human body static electricity, human body electric shock and reduce the occurrence of electrostatic damage to electronic components?
Static elimination ball, also known as electrostatic discharge instrument, electrostatic ball. It is a human body electrostatic discharge product suitable for flammable, explosive and anti-static places. The product is suitable for computer rooms, dust-free workshops, power stations, gas stations, oil refineries, thermal power plants and other fields.
Its working principle is: adopt a kind of passive circuit, use the static electricity on the human body to make the circuit work, and finally achieve the effect of eliminating static electricity. The characteristics of the static elimination ball are: small size and light weight. No power is required. Easy to install. No feeling when eliminating static electricity. Just touch the stainless steel ball 0.1S with your finger to eliminate the static electricity of the human body.
