Mounting method of grounding wire of extra-high-voltage transformer

[0017] Embodiment: A method for installing a ground wire of an UHV transformer, including an UHV transformer, a first electric pole, a second electric pole, a first copper rod, a second copper rod, and a horizontal support frame; The second telegraph pole is kept at a certain distance, the lower ends of the first telegraph pole and the second telegraph pole are deeply buried in the soil; the upper port of the first telegraph pole is closed; the upper port of the second telegraph pole is closed The horizontal support frame is fixed between the first and second telephone poles, and the UHV transformer is installed on the horizontal support frame; the lower end of the first copper rod is buried in the soil, but the first The copper rod is located inside the first electric pole, and the upper end of the first copper rod is connected to the metal shell of the UHV transformer through a high-voltage cable; the lower end of the second copper rod is buried in the soil, but the second copper rod is located Inside the second telegraph pole, the upper end of the second copper rod is connected to the metal shell of the UHV transformer through a high-voltage cable.

[0018] Principle description: The present invention cleverly arranges the grounding copper rod inside the electric pole, so that thieves cannot steal the copper rod, and the upper ports of the first electric pole and the second electric pole are both closed, and rainwater cannot enter, which also prevents the copper rod from entering. It is easily oxidized, so that the grounding conductivity of the copper rod will not decrease for a long time.
