Background technology
Grounded screen is the indispensable facility that guarantees generating, power transformation and transmission system equipment safety operation and personal safety, and is generally buried in the 50-80cm soil of underground by downlead.The grounded screen zinc-plated carbon steel of mainly drawing materials, be in complicated soil environment for a long time.Water in soil, negative ion, kation, microorganism all can be deepened the corrosion of zinc-plated carbon steel.In case the fracture of grounded screen corrosion, when running into thunderbolt, short trouble, electric current just can not import the earth by grounded screen, so, will be easy to make power transmission and transforming equipment burn, and causes huge economic loss.Therefore, the corrosion condition of research grounded screen, the extent of corrosion of assessment grounded screen is the major tasks of electric system always.Yet grounded screen is buried underground, is difficult to check intuitively its corrosion condition.Only expend a large amount of manpower and materials, dig out soil, just can check, can bring very large difficulty to real work like this.Estimate at present the mode of soil to the corrosion of grounded screen, a kind of is to bury sheet by scene, through after a while its taking-up being weighed, so as to calculating corrosion rate.Make in this way the corrosion rate of calculating more credible, but test 1-2 at least of required time, more than 10 years at most, excessive cycle; Another kind method is to extract the soil liquid, and at the electrochemical method soil erosion researching of use for laboratory three-electrode system, the cycle is short, but experimental data is often larger with actual difference.Therefore have the people to imagine, if utilize at the scene electrochemical method to measure soil corrosion rate, not only the cycle can be short, and data are credible.But the laboratory three-electrode system is respectively working electrode, platinum electrode, saturated calomel electrode, and they can't use in soil environment at the scene, thereby have limited the application of electrochemical method.
The utility model content
The technical problems to be solved in the utility model is, backward situation for prior art, for solving the technical barrier of the electrode assembly of measuring soil corrosion rate, a kind of electrode assembly of measuring soil corrosion rate is provided, measure soil corrosion rate, the extent of corrosion of rapid evaluation soil to grounded screen in order to use at the scene electrochemical method.
Technical solution of the present utility model is, a kind of electrode assembly of measuring soil corrosion rate that provides, and referring to Fig. 1～2, it has a cartridge type sleeve pipe 2 as shown in Figure 1.As shown in Figure 2, radially be radial at least three cylindrical electrodes 1 that are evenly distributed with in this sleeve pipe 2.The axis of described electrode 1 is parallel with the axis of described sleeve pipe 2.The axial bottom face of described electrode 1 and described sleeve pipe 2 one bottom faces are with in one plane.The axial other end bottom surface of described electrode 1 in sleeve pipe 2 and through solder joint 4 welding one wires 5, these wire 5 other ends namely outwardly an end stretch out sleeve pipe 2.In addition, filling has epoxy resin 3 between the inwall of described electrode 1 and described sleeve pipe 2.
While by the above of the present utility model a kind of electrode assembly of measuring soil corrosion rate that forms, being used, can coordinate with the peripheral hardware electrochemical workstation.For example three electrodes 1 of this device can be connected respectively the working electrode, contrast electrode of electrochemical workstation, to electrode connection to form three-electrode system, and these three electrodes are inserted in soil, utilize electrochemical workstation to carry out conventional Tafel polarization curve and measure, then use commercially available special-purpose soil corrosion rate to calculate software and calculate the soil corrosion rate of soil to be measured.Above-mentioned three electrodes 1 are drawn materials unanimously, therefore can further measure as required the corrosion rate of metal material in soil of making these three electrodes 1.
The beneficial effects of the utility model are:
1), electrode uses material of the same race to make, distribute spacing equates, therefore make polarizing voltage be evenly distributed, measuring speed is fast, accuracy is high;
2) but in-site measurement various metals material soil corrosion rate is applied widely;
3), simple in structure, with low cost, easy to operate, safeguard easily.
