Sealing device for overhead ground wire online electrochemical testing and testing method thereof

Abstract

The invention discloses a sealing device for overhead ground wire online electrochemical testing. The device comprises a hollow groove body and a groove body which can be vertically combined oppositely, an elastic sealing piece arranged in a through hole and used for being matched with an overhead ground wire to be tested, and a clamping mechanism for clamping opposite combination of the hollow groove body and the groove body, wherein the through hole for being matched with the overhead ground wire to be tested is formed between the hollow groove body and the groove body. According to the scheme, due to the through hole between the hollow groove body and the groove body, through type installation of the overhead ground wire to be tested is achieved to achieve the purpose of online testingof the overhead ground wire to be tested. By arranging the elastic sealing piece, a testing cavity between the hollow groove body and the groove body is isolated from the outside world. Due to the clamping effect of the clamping mechanism, the obstruction effect of the testing cavity and the outside world is further enhanced, the water sealing performance of the testing cavity is greatly ensured,and the overhead ground wire testing reliability is improved. The invention discloses an overhead ground wire online electrochemical testing method applying the sealing device.

Description

technical field [0001] The invention relates to the technical field of electrochemical detection of overhead ground wire corrosion, in particular to a sealing device for on-line electrochemical testing of overhead ground wires and a testing method thereof. Background technique [0002] Electrochemical testing is commonly used in pre-prediction or post-assessment techniques for the corrosion resistance of samples to be tested, such as electrochemical impedance, potentiostatic polarization, and potentiodynamic polarization, etc. detection. [0003] At present, most of the corrosion detection devices for electric power overhead ground wires are suitable for decommissioned overhead ground wires, and the detection work of in-service overhead ground wires is cumbersome and inefficient. In the overhead ground wire corrosion test, the device is rarely used to test the middle part of the overhead ground wire, because in the actual test process, especially for the overhead ground wir...
