The high-voltage ground wire is used for line and substation construction to prevent electrostatic induction electric shock or false closing of nearby electrified body. Precautions to be taken when operating the high-voltage grounding wire of the operation rack, including:

1. Check the high-voltage grounding wire before work. Whether the soft copper wire is damaged, whether there is or is not loose elastic steel wire hook bolt connection is normal, and if it does not meet the requirements, it should be exchanged or repaired in time before use.

2. When driving the grounding pile, it is necessary to select the field surface with strong cohesiveness, more organic matter and humidity, and avoid the loose, hard weathering, backfill and dry surface layer. The purpose is to reduce the soil of the grounding circuit resistance and contact resistance, and quickly remove the accident current to ensure the ground quality.

3. Prior to hanging the high-voltage ground wire, the power must be tested first. The high-voltage ground wire that is not encountered is often seen in the Habitual Violation of the grass-roots level. The purpose of the high-voltage ground wire and power supply inspection is to confirm whether the website has the power to cut off the power. The human error of stopping the wrong power supply can be eliminated and the power can not be cut off, so as to prevent hanging the high-voltage ground wire on site.

4. Protect the high-voltage grounding wire. Flowers shall not be used during the high-voltage ground wire. When removing unsoft copper plates, the high-voltage ground wire shall be twisted and shall not descend from the air or any disorder in autumn. The wire shall be transmitted by ropes. Pay attention to the high-voltage cleaning of the ground wire to prevent sediment and sundries from entering the pores of the grounding device, so as to affect the normal use of the parts.

5. Select the corresponding specifications of high-voltage grounding wire by different voltage levels. It is also the diameter of the earth that matches the rated voltage of electrical equipment that can be easily violated by accident at present.
