Abstract

The invention discloses a multifunctional catholic protection test probe and a test method. The probe comprises an insulation shell, a test sample, a reference electrode and multiple cables, wherein the insulation shell is hollow and is internally provided with a sealed cavity, which is divided into an upper closed cavity and a lower closed cavity, the reference electrode is arranged in the lower cavity, and the insulation shell is manufactured by an insulation material; the test sample is arranged outside the insulation shell, and the test sample adopts a material, which is the same as a measured metal component; each of the multiple cables comprises a test sample cable and a reference electrode cable, one end of the corresponding cable is respectively electrically connected with the corresponding test sample and the reference electrode, and the other end of each corresponding cable is extended from the insulation shell. The test method is a test method, which is capable of testing a catholic protection effect and alternating current / direct current disturbance degree of underground or underwater metal structure by adopting the multifunctional catholic protection test probe.

Description

technical field [0001] The invention relates to the technical field of cathodic protection detection, in particular to a multifunctional cathodic protection test probe and a test method, which are mainly used for measuring the natural corrosion potential, cathodic protection polarization potential, alternating current density and direct current density of buried or underwater metal components and other parameters. Background technique [0002] Cathodic protection has been widely used as a cost-effective method to prevent corrosion of buried or underwater metal components. Polarization potential is a key parameter of cathodic protection, which marks the degree of cathodic polarization. An important indicator of protection effectiveness. At present, the indicators for evaluating the effectiveness of cathodic protection both at home and abroad use polarization potential or polarization value (the offset value of polarization potential relative to natural corrosion potential). ...
