Problems solved by technology

However, on-line detection requires in-situ testing of metal components under almost non-destructive conditions. The process cannot cause adverse effects on transmission lines, and it is even more impossible to cut off grid equipment components to prepare working electrodes. Therefore, under existing conditions The described online measurement is difficult to achieve

Embodiment 1

[0031] Refer to attached figure 1 , an electrolytic cell device based on the online electrochemical measurement of the transmission line, including an electrolytic cell and a fixing clip, etc., wherein the electrolytic cell includes an electrolyte container 1 with an upward opening, a workpiece connection part 2 and a square partition 3, and the electrolyte container 1 It is a square columnar structure, which is surrounded by four plates with a certain thickness. The bottom end surface and the square partition 3 are fixedly connected by glue, thus forming a square container with the square partition as the bottom. At this time, the square partition The area of ​​the plate 3 is larger than the cross-sectional area of ​​the electrolyte container 1 , and its periphery protrudes to form a square ring-shaped boss 5 . The workpiece connection part 2 is a columnar member, which can be a square columnar member or a cylindrical member. A cylindrical through hole 4 is opened along the c...

Embodiment 2

[0035] Refer to attached figure 2, the electrolyte container 1 is a square columnar structure, which is surrounded by four thick plates and square partitions. At this time, the square partition 3 is used as the side panel of the electrolyte container 1, and the remaining four thick plates are the other three Side panels and a bottom plate, the workpiece connection part 2 is located on the outer surface of the square partition 3, and its axis is perpendicular to the axis of the electrolyte container 1. Such a structure is suitable for electrochemical measurement when the measured surface of the metal component is a vertical surface. The workpiece connecting portion is transversely perpendicular to the surface of the workpiece, and its cylindrical through hole also passes through the square partition and communicates with the inner cavity of the electrolyte container. The parts not described in this embodiment are the same as those in Embodiment 1.

Description

technical field [0001] The invention relates to an electrochemical measurement device, in particular to an electrolytic cell device based on the on-line electrochemical measurement of a power transmission line. Background technique [0002] The metal components (workpieces) of transmission lines are in the atmospheric environment. Due to the environmental effects of wind, sun, rain erosion and other environmental effects for many years, steel structure transmission poles and other metal parts generally suffer from severe corrosion, which constitutes a major threat to the safe operation of transmission lines. Hidden danger. Power grid transmission accidents caused by corrosion of power transmission equipment occur from time to time, causing huge economic losses, seriously restricting the development of power grids, and affecting the safety and stability of power production. Therefore, monitoring the metal equipment of transmission lines is of great significance to ensure the...
