Large range long distance cathodic protection system and working method thereof

Abstract

The invention relates to a large range long distance cathodic protection system which comprises a control center, constant potential rectifiers and intelligent potential collectors. A plurality of constant potential rectifiers and intelligent potential collectors are arranged. The control center is internally provided with a potential regulating system and a memory. The large range long distance cathodic protection system is provided with the constant potential rectifiers and an output unit connected with the constant potential rectifiers. The constant potential rectifiers are arranged along a protective line pipe. Output number of the constant potential rectifiers is great so that the cathodic protection is long in distance and uniform in protection. According to the large range long distance cathodic protection system provided by the invention, the output potential can be automatically adjusted, and the adjusting error is small. Automatic adjustment is realized, so that the cathodic protection at each monitoring point on the whole line pipe meets the standard or most monitoring points meet the standard.

Description

technical field [0001] The invention relates to a cathodic protection system, specifically, a large-scale and long-distance cathodic protection system and its working method. Background technique [0002] With the development of the economy, the number of buried metal pipes and metal equipment continues to increase, and these metal pipes and metal equipment buried underground for a long time are prone to corrosion. Cathodic protection is one of the main methods of corrosion prevention at present. For large areas, Buried metal pipelines and metal equipment with long distribution distances require long-distance cathodic protection. However, the current long-distance cathodic protection systems have fewer output channels, fewer potential detection points, and short protection distances. They can only rely on manual detection and manual protection. Adjust the cathodic protection of all objects in the area to meet the standard, the adjustment error is large, it cannot automatical...
