Leakage principle of cordless anti-static wrist strap
CordlessAnti-static wrist strapIt has the function of eliminating static electricity without a grounding wire. Compared with the corded anti-static wrist strap, the cordless anti-static wrist strap only retains the conductive bracelet on the inner side, while other parts are removed (such as wiring buttons, grounding wires, etc.), and the main body for leakage is added. part. At present, there are not many applications of cordless anti-static wrist straps, but in factories that need electrostatic protection, relevant production managers will use it, because it solves the problem of managers needing to move around and supervise production. Here is a brief introduction to the working principle of the cordless anti-static wrist strap.
The working principle of the cordless anti-static wrist strap: Set the main body of the wrist strap as the transmission area, and inject ion exchanger into it, and add 1MQ resistance between the transmission area and the release point. When the static electricity in the human body passes through the collection area, that is, the inner loop wire yarn and the stainless steel sheet enter the cordless anti-static wrist strap, and react with the ion exchanger placed in it to produce a neutralizing effect, thereby completing the elimination of static electricity. the goal of.
The leakage principle of the cordless anti-static wrist strap: The leakage principle actually uses the corona discharge principle to discharge electricity, which is a gas self-excited conduction phenomenon. It usually occurs in areas with high voltage. Because of the high voltage of air in this area, the radius of curvature of the charged body will be small, which promotes the collision ionization of gas molecules like avalanche, thus forming self-excited conduction. . During corona discharge, the ionization and luminescence of gas are confined to the thin layer of atmosphere near the electrode surface, which is called the "corona layer". In the outer space of the electric layer, due to the weak electric field, collision ionization does not occur, and the use of corona discharge can make the charge accumulated on the cordless anti-static wrist strap gradually leak.
