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

Abstract

The invention discloses a mounting method of a grounding wire of an extra-high-voltage transformer. According to the mounting method, the extra-high-voltage transformer, a first telegraph pole, a second telegraph pole, a first copper rod, a second copper rod and a horizontal supporting frame are included; the lower end part of the first copper rod is embedded in soil while the first copper rod is positioned in the first telegraph pole; the upper end part of the first copper rod is connected with the metal shell of the extra-high-voltage transformer through a high-voltage cable; the lower end part of the second copper rod is embedded in soil while the second copper rod is positioned in the second telegraph pole; and the upper end part of the second copper rod is connected with the metal shell of the extra-high-voltage transformer through a high-voltage cable

Description

technical field [0001] The invention relates to a method for installing a ground wire of an extra-high voltage transformer. Background technique [0002] In my country, UHV generally refers to the voltage level of 1000 kV and above AC. The requirements for the grounding wire of UHV transformers are much higher than those of ordinary transformers. The grounding wires of UHV transformers require higher conductivity, especially for embedded It is better to make the metal block in the soil with copper material, but a common problem with the existing transformer grounding wire is that the long metal block of the grounding wire exposed above the ground is easy to be stolen by thieves, which brings safety problems to the transformer. A big hidden danger. Contents of the invention [0003] The object of the present invention is a method for installing the ground wire of an ultra-high voltage transformer. [0004] In order to achieve the above objectives, the technical solution ado...
