As the name suggests, the wire grounding line is actually a line that connects with the earth. It can also be called a safety circuit line when it is said. When there is an emergency danger, the existing high voltage is directly converted to the earth. It can be said to be a safety line.
Regarding the specification of the grounding wire of the electric wire, the national electric power industry has strict requirements. In order to avoid the accidental high-voltage danger in the equipment and the line of the power outage, the wire grounding wire specification should be more than 25mm2, and the product made of bare copper wire. .
First, the wire grounding line
1. In many home appliances, because the performance of the product is not superior, it is easy to let the shell of the home appliance produce a certain electrostatic effect for a long time in a humid environment. If the situation is serious, it is easy to have electric shock. In order to solve this problem, a ground wire is usually connected to the outer casing of these home appliances, and the other end is connected to the ground. In the event of leakage, the ground wire will immediately discharge static electricity to the ground, effectively avoiding the occurrence of safety hazards.
2. The wire grounding wire also has a very good effect on the soldering iron soldering circuit. Because the electric soldering iron is easy to damage the circuit in the electrical appliance, the electrical maintenance personnel will connect the ground wire. In addition, many people engaged in the computer industry often ignore the connection of the ground wire for the host. In fact, accessing a ground wire can prevent the occurrence of the crash problem to a certain extent.
3. For the communication industry, the wire grounding wire is also frequently used, because the communication line voltage is not high, it is easy to have electromagnetic interference affecting transmission. Although all the shielding layers of the communication line can block electromagnetic interference, if the ground wire is connected, the generated voltage will be released to the ground to make the communication more normal, and the signal in the communication is prevented from being interfered by the outside. However, after the work is completed, the ground wire should be removed in time to avoid damage to the equipment and affect the use.
Second, the wire grounding line color
The ground wire is connected to one end of the line to the outer casing of the electric appliance, and the other end is connected with the earth to effectively reduce the occurrence of electric shock. In the circuit used in the decoration space, the fire line is usually represented by yellow, the zero line uses the blue line, and the yellow-green line is the ground line.
