Hazards of Static Electricity
In the electrical industry, with the accelerating pace of globalization, large enterprises, especially those with international backgrounds, are increasingly clarifying and deepening their requirements for static electricity prevention. Static electricity in this field can cause explosions and fires, electric shocks, and production disruptions.
1. Explosions and Fires: Although the amount of static electricity is small, its high voltage makes it prone to discharge, generating static sparks. In workplaces with flammable liquids (such as oil transportation sites), static sparks can cause fires; in workplaces with explosive dust or explosive gases and vapors (such as coal powder, flour, aluminum powder, hydrogen, etc.), static sparks can cause explosions.
2. Electric Shocks: When a human body approaches a charged object, the static charge on the human body (which can reach tens of thousands of volts) can cause an electric shock when it approaches a grounded object. Because the energy of static electricity is very small, an electric shock is not usually fatal, but it can cause secondary accidents due to falls.
3. Production Disruptions: In some production processes, failure to eliminate static electricity can hinder production or reduce product quality. For example, in the manufacturing of low-voltage electronic products, static electricity remaining on high-precision manufacturing equipment may affect manufacturing accuracy, increase scrap rate, and cause malfunctions; static electricity on components may cause signal instability in the entire electrical switching device after packaging, causing direct or indirect harm.
"Static ball" mainly refer to two types of products: static eliminators (human body static dischargers) used in industry and security, and glow spheres (plasma lamps) used for science education and decoration. Both play key roles in safety protection and science education displays, respectively.
Industrial and Explosion-Proof Safety: Static eliminators are commonly installed at entrances to flammable and explosive areas such as gas stations, chemical plants, oil depots, and machine rooms.
Safe Release: When a person touches the metal sphere, it safely conducts the accumulated static charge to the ground.
Accident Prevention: Prevents sparks generated by static discharge from the human body, thereby preventing fires or explosions.
