A complete set of device and method for preventing grid overcurrent from entering the ground for buried oil and gas pipeline network

Abstract

The invention discloses a complete set of device and method for preventing grid overcurrent from entering the ground of a buried oil and gas pipeline network. The device includes an oil and gas pipeline, and a plurality of drain needles are installed on the surface of the oil and gas pipeline on the side of the oil and gas pipeline facing the grounding device of a transmission tower through an insulating base. , and a first copper bar is arranged along the axial direction of the pipeline, and the drain needle is electrically connected through the first copper bar. The row is connected to the first copper row. In the invention, a drain needle is arranged on the oil and gas pipeline, and a copper bar and a drain net are arranged to drain and discharge the overcurrent into the deeper soil far away from the oil and gas pipeline, so as to avoid the potential rise and direct damage caused by the overcurrent to the oil and gas pipeline. Reasonably restrict the flow of ground overcurrent to buried oil and gas pipelines, and play a role in reducing the soil potential near the oil and gas pipelines, which can greatly avoid the damage of buried oil and gas pipelines caused by ground overcurrent. powerful.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a complete set of devices and methods for preventing grid overcurrent from entering the ground for a buried oil and gas pipeline network. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for fossil primary energy such as oil and natural gas and electric energy in social production and residents' life has been increasing. energy delivery becomes necessary. Under this background, my country has built many power transmission lines and oil and gas transmission and oil and gas pipelines. Due to the effective use of land resources, there must be shared public corridors between these transmission lines and oil and gas pipelines, and a large number of power transmission channels and oil and gas pipelines are parallel. even transcendence. [0003] When the transmission tower is struck by lightning ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a buried oil and gas pipeline network anti-grid overcurrent complete set, which can solve the problem in the prior art that buried oil and gas pipelines are damaged due to lightning strikes on transmission towers or ground faults on transmission lines
