1, the role of the grounding wire
a, the protection of personal safety
As a result of electrostatic discharge is prone to generate a large number of charges, if the electrical equipment does not get proper isolation, it will be very easy to electrical appliances and human body caused by a great deal of damage, and the role of the grounding wire is just to become a high-voltage equipment and the earth between the conductor, to play a role in avoiding us to be damaged by the purpose of the electric charge.
b, lightning
Placed in the past, once the occurrence of thunder and rain, utility poles and other equipment are often damaged because of lightning strikes, sometimes even days can not be used, so the role of the grounding wire in the role of lightning can be a very good protection, effectively extend the service life of electrical equipment.
c, to ensure normal operation
For some must have electricity to work, such as medical work, the role of the grounding wire is to avoid power outages encountered when the unexpected situation, not to be affected, still be able to operate normally a small load reference potential.
2, how to ground themselves
a, standardized operation
Purchase good quality flat iron (preferably up to 1M, thickness of more than 30MM and corrosion-resistant iron and steel materials) or similar materials as grounding stakes, so that the role of the grounding wire to get a better play to, in addition, it should be noted that the choice of staking the area, to choose the surroundings of the lesser people and animals walking around the place, it is recommended that the grounding wire is not used for the purpose of the grounding wire. and animals walking around the place, it is recommended to weld the way of operation, welding carefully check whether there is no loose or poor contact, if any, it is necessary to repair immediately, otherwise, once caused by leakage, the consequences are unimaginable.
b, add shell
Shell in the role of the grounding line plays a role can not be underestimated, so if you want to achieve a more secure electricity, you may wish to consider a high-quality, tight plastic pipe to add a shell for the appliance and then grounded, but do not use the gas pipeline or other people have access to the material to act as a grounding stake.
c, qualified plugs and sockets
To achieve strong protection of the power supply function, qualified quality plugs and sockets in the home on the cable can create a complete grounding protection system.
