Title:
CATHODE PROTECTION TEST PROBE
Document Type and Number:
WIPO Patent Application WO/2020/244107
Kind Code:
A1
Abstract:
Disclosed is a cathode protection test probe, comprising an outer cavity, a polarized test piece, an inner cavity, an alternating-current test piece, a copper electrode and a test cable, wherein the polarized test piece is of a hollow cylinder shape; the polarized test piece wraps an outer wall of the outer cavity; the polarized test piece, the outer cavity and the inner cavity are coaxially arranged; the polarized test piece is fixed on the outer wall of the outer cavity; the alternating-current test piece is embedded into an inner side of the top of the outer cavity; the copper electrode is inserted into a lumen of the inner cavity from the center of the bottom of the outer cavity and is fixed to the outer cavity and the inner cavity in a sealed manner; a copper sulfate crystal is filled between the copper electrode and an inner wall of the inner cavity; and three wires of a three-core test cable are respectively connected to the polarized test piece, the alternating-current test piece and the copper electrode. The cathode protection test probe uses the polarized test piece of a hollow cylinder shape to surround a test electrode so as to eliminate impurity current interference, and uses an all-solid-state structure involving no leakage and no pollution of the test piece for a test, making a test result more reliable.
