The principle of anti-static double-hole grounding wire protection is that after the object is grounded, the electrostatic charge generated on the surface of the object will be discharged into the ground, so that it will not gather to the high voltage that can endanger the safety of the human body.
The function of the wire connection is to connect the conductive part of the metal shell of the electrical equipment or the electric cabinet and the electric equipment with the earth to form an equipotential body. In this way, even if the electrical equipment enclosure leaks accidentally, the current will flow to the ground through the connection wires, which is the same as the ground potential. Therefore, people standing on the ground touching the electrical cabinets and electrical equipment enclosures will not have voltage applied to the human body.
The anti-static double-hole grounding wire is connected to the ground to form an equipotential body. Doesn't the current flow to a low potential? Therefore, if people stand on the ground and touch the electrical cabinets and electrical equipment shells, there will be no voltage applied to the human body, and the current can not flow to the ground through people?
The resistance of the anti-static double-hole grounding wire is very small. When the current flows from the electrical box shell to the ground through the connecting wire, the voltage drop of the line is very small, that is to say, the voltage between the electrical box shell and the ground is very low and can be ignored. Therefore, even if the human body touches the shell of the electric box, even if there is voltage applied to the human body, because the voltage is very low, the current passing through the human body is much smaller than the current of the human body for electric shock (usually 15mA), and the human body will not get an electric shock.
An anti-static double-hole grounding wire is a supporting part of the chemical storage cabinet. According to relevant regulations, electrostatic grounding measures should be taken for equipment and pipes in explosion and fire hazardous locations that may generate electrostatic hazards. Solid storage facilities should also have electrostatic grounding facilities. The container for storing flammable liquids and the accumulation of electrostatic charges on the human body are the origin of electrostatic sparks. Electrostatic sparks may cause flammability during the storage, transmission or distribution of flammable liquids. Liquid deflagration. Therefore, in accordance with OSHA's standards and safety practices for flammable liquids, when flammable liquids are transferred from drums to containers, as well as the safety cabinets that store flammable liquids, the standing grounding device must be connected to the drum through an anti-static grounding wire clamp. And the safety cabinet is reliably grounded, and the static charge is led into the ground to prevent fire accidents caused by static sparks.
