Abstract

The invention relates to a cable conductor DC resistance on-line detection device and a method thereof, aiming at solving the problems of the prior art that detection to a cable conductor needs to cut a section of the cable conductor, which brings inconvenience to operation and causes material waste; the detection is apt to be influenced by air humidity, air temperature and sample temperature and other factors; and the accuracy of detection results is low. The cable conductor DC resistance on-line detection device comprises a resistance tester, a mobile trolley, a potential clamp and a current clamp, wherein the resistance tester is arranged on the mobile trolley; a water tank for containing cables is arranged on the top end of the mobile trolley; the potential clamp and the current clamp are used for clamping cables and connected on the resistance tester through wires. The invention has the advantages of optional movement, convenient use, waster reduction and high detection structure accuracy.

Description

technical field [0001] The invention relates to a cable conductor detection device, in particular to a cable conductor DC resistance online detection device and method. Background technique [0002] DC resistance is a very important index in the cable electrical performance inspection project. General cable conductor testing instruments are placed in the laboratory, which is inconvenient to move. If you want to test the cable conductor, you need to intercept one end of the cable conductor and take it to the laboratory. This is not only inconvenient, but also causes waste of materials, because this This method requires 1.5x2 meters to test each cable. For example, if the production of 240mm2 conductors is cut by 3 meters, a total of 6kg of copper will be wasted, and the cable conductor will be loose due to the cut-off, resulting in poor contact and affecting the accuracy of the measurement. In addition, the cable conductors are heated during twisting, and the temperature nee...
