Abstract

The invention belongs to the technical field of nuclear power maintenance and particularly relates to a nuclear power plant buried pipeline cathode protection effectiveness monitoring system. According to the nuclear power plant buried pipeline cathode protection effectiveness monitoring system, the difference between the on-potential and the off-potential of a test block can comprise the ohmic drop generated by an impressed current cathode protection system in the testing process and can further comprise the ohmic drop generated by a sacrificial anode system and disturbance of other stray currents, and therefore, by means of the difference between the on-potential and the off-potential of the test block, the ohmic drop generated in the testing process can be determined in a more-comprehensive manner under the circumstance that a to-be-tested pipeline cannot be disconnected from a sacrificial anode; and furthermore, the cathode protection potential of the determined to-be-tested pipeline can reflect the actual state of cathode protection of the to-be-tested pipeline more precisely.

Description

technical field [0001] The invention belongs to the technical field of nuclear power maintenance, and in particular relates to a cathodic protection effectiveness monitoring system for buried pipelines of nuclear power plants. Background technique [0002] The buried steel pipelines of nuclear power plants are laid underground, and the combination of anti-corrosion layer and regional cathodic protection is usually used to slow down the soil corrosion. However, with the increase of the service life of buried pipelines, the corrosion protection layer will inevitably degrade; in addition, corrosion layer defects will inevitably occur during processing, installation and maintenance, and the cathodic protection system will be the last important Barrier to slow down the soil corrosion of the pipe body at the defect of the anti-corrosion coating. [0003] The evaluation of the cathodic protection potential at the defect of the anticorrosion layer of the buried pipeline is one of t...
