Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline maintenance equipment, in particular to a device for facilitating pipeline potential testing. Background Art
[0002] The existing test pile lines have stray current interference and the pipeline is protected by multiple power supplies at the same time. All power supplies need to be turned on and off synchronously, which is difficult to operate, and the power-off potential cannot be accurately detected, resulting in meaningless power-off potential measurement and inconvenience in testing. The traditional pipeline potential test device does not clearly mark the line, resulting in the inability to clearly determine the test line. During the test, the red and black test pens need to touch the test points at the same time and read the data. It is difficult for one person to complete the test task, and because the test points are prone to rust, the measurement data will be inaccurate. Utility Model Content
