Pipeline cathodic protection and interference comprehensive console

Abstract

The invention provides a pipeline cathodic protection and interference comprehensive console. According to the structure of the console, an industrial personal computer is used for controlling connection and disconnection of electronic switches of a potentiostat output switching unit and an interference state switching unit so as to control the signal output state of the potentiostat, a rectifier and a voltage regulator; the signal output end of the potentiostat is connected with a cathodic protection external circuit; the signal output end of the rectifier is connected with a direct current interference external circuit; the signal output end of the voltage regulator is connected with an alternate current interference external circuit; and information of external circuits is transmitted to the industrial personal computer by a data collection module, and is displayed by output equipment on the industrial personal computer. By adopting the structure and method, the technical problems that the true environment of a pipeline is difficult to reappear and the requirements for verifying accuracy of detection equipment and detection process cannot be met in the prior art can be solved.

Description

technical field [0001] The invention belongs to the technical field of oil and gas pipeline detection, and in particular provides an integrated analog control device for pipeline cathodic protection and interference working conditions. Background technique [0002] Cathodic protection is an important part of maintaining the integrity of buried pipelines. The national standard [GB / T Technical Specifications for Cathodic Protection of Buried Steel Pipelines] requires new or existing pipelines to adopt or add cathodic protection measures. With the construction of public corridors, AC and DC interference has become more common and has become an important factor jeopardizing the integrity of pipelines. Periodic detection of cathodic protection system operation status and AC / DC interference has been included in a number of national and industry standards [GB32167 Oil and Gas Transmission Pipeline Integrity Management Specifications] [SY / T0087.1 Direct Evaluation of External Corros...
