Description

technical field [0001] The invention relates to the field of circuit protection devices, in particular to a current supplementary device for cathodic protection of solar gas pipelines. Background technique [0002] Cathodic protection current is a kind of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes a cathode, so that the electron migration of metal corrosion is inhibited, and the corrosion is avoided or weakened. Cathodic protection has been developed for many years, and the industry has summed up the current density required by cathodic protection systems in various environments, which can be used as a reference in actual construction in the future. However, the current density recommended in the past was too conservative, resulting in a lot of material energy. Therefore, when carrying out a project, investigate the structure in the local similar envi...
