Cathode protection test device and test method thereof

Abstract

The invention provides a cathode protection test device and a test method thereof. The cathode protection test device comprises a cathode protection tester and a cathode protection test pile; aviationplugs are arranged on the cathode protection tester and the cathode protection test pile correspondingly; the device further comprises a cable connecting the two aviation plugs, the cathode protection test pile comprises a column body, a hollow panel placement hole is formed in the column body, a wiring board is arranged in the panel placement hole, a binding post is arranged on the wiring board,and the aviation plug of the cathode protection test pile is located on the wiring board, and is connected with the binding post; a threading hole penetrates from the bottom end of the column body and straightly penetrates to the position of the panel placement hole, one end of a test cable is connected with the binding post after passing through the threading hole, and the other end of the testcable is connected with a test piece, a reference electrode, a pipeline and a sacrificial anode correspondingly; and the cathode protection tester realizes the parameter measurement through a manual switching switch, a universal meter, a positive electrode jack and a negative electrode jack, wherein the positive electrode jack and the negative electrode jack are externally connected with the universal meter. According to the device and the method, the rapid measurement of the cathode protection parameters is realized, and the working efficiency of field workers is improved.

Description

technical field [0001] The invention relates to the field of cathodic protection and cathodic protection data collection, in particular to a cathodic protection testing device and a testing method thereof. Background technique [0002] As the most effective anti-corrosion measure for pipelines, cathodic protection technology has been paid more and more attention by domestic pipeline companies and oil companies, but there is still a certain gap compared with foreign developments. This is mainly reflected in the pipeline cathodic protection status testing, evaluation methods, Means and equipment are backward. [0003] At present, using -850mV natural potential as the effective potential criterion of cathodic protection has been difficult to deal with the corrosion caused by complex external conditions. Pipeline cathodic protection potential test is carried out in the energized state. There is cathodic protection current in the soil. The pipe-to-ground potential measured by th...

Problems solved by technology

However, cathodic protection testing methods basically use manual testing. The cathodic protection parameters are directly measured through a digital multimeter, which requires on-site personnel to manually connect and restore after measurement. This method has poor operability and high labor intensity. High professional knowledge, the most important thing is that it is easy to cause inaccurate measurement data and waste of financial resources

Except for a few pipeline companies that have adopted automatic data collection devices, after collecting data, they will be processed and sent to the dispatching center through GPRS (General Packet Radio Service) equipment, and then through the control software program. In some cases, there is no cathodic protection equipped with automatic data acquisition devices, and there is a lack of reasonable testing methods and tools
