Cathode protection shielding effect testing device and method

The invention discloses a cathode protection shielding effect testing device and method, and belongs to the field of pipeline corrosion protection. The cathode protection shielding effect testing device comprises a measuring assembly, a power supply assembly and a pipeline simulation assembly located in an electrolyte solution. The pipeline simulation assembly comprises a substrate, a plurality of electrodes arranged on the substrate in an array mode and an anti-corrosion layer laid on the electrodes. By means of the device, the relation between the anti-corrosion layer stripping parameters of the pipeline and the shielding effect of the cathode protection current can be obtained through testing, and then the cathode protection shielding problem of the pipeline can be evaluated and solved conveniently according to the relation. And the device can be used for measuring and analyzing the cathode protection shielding effect of the pipeline, so that the problem that the cathode protection shielding effect cannot
