The invention discloses a conductor resistance measuring device which is used for performing dynamic on-line detection on cable conductor resistance. The conductor resistance measuring device comprises a base, a first light touch mechanism, a second light touch mechanism and a resistance detection device which can exert a specific voltage to generate a current and measure the current, wherein the first light touch mechanism, the second light touch mechanism and the resistance detection device are all installed on the base. The first light touch mechanism comprises a conductive first connecting piece, one end of the first connecting piece is connected with the resistance detection device in a conductive mode, and the other end of the first connecting piece makes contact with a cable conductor to be detected. The second light touch mechanism comprises a conductive second connecting piece, one end of the second connecting piece is connected with the resistance detection device in a conductive mode, and the other end of the second connecting piece makes contact with the cable conductor to be detected. The distance between the contact point of the first connecting piece and the cable conductor to be detected and the contact point of the second connecting piece and the cable conductor to be detected is not less than the diameter of the cable conductor to be detected by two times.
Description
technical field [0001] The invention relates to the technical field of conductor resistance detection, in particular to a wire resistance measuring device for dynamic on-line detection of cable wire resistance. Background technique [0002] Resistance is a very important index in the cable electrical performance inspection project. According to Ohm's law, resistance can be measured by applying a certain voltage to the element to be detected and obtaining the magnitude of the current formed under the voltage. The ratio of the voltage value to the current value is the resistance value of the element. The detection of general cable conductors is carried out by intercepting a section of cable conductors and taking them to the laboratory, which is not only inconvenient, but also causes waste of materials. At the same time, the cable will also be affected by many factors such as air humidity and air temperature during detection, making the measurement results inaccurate. Conten...
