Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and in particular to a cable broken core detection device. Background Art

[0002] During cable use, core breakage is unavoidable. This refers to the partial breakage of the cable's internal core, which can affect the cable's transmission performance. For already installed cables, when a core breakage occurs, it is usually necessary to first locate the breakage, then cut the cable at that location and replace it with a new cable segment for repair. Therefore, quickly determining the location of the breakage is key to quickly resolving the issue. A core breakage, when the conductor inside a cable breaks or separates from the insulation, can cause serious consequences in power systems, including equipment damage, circuit failures, and even fires.

[0041] The working principle of the present invention is as follows: before testing, first use force to bend the two guide rollers 54, pass one end of the cable 3 between the two guide rollers 54, then push the cable 3 through the middle of the upper and lower groups of support rollers 49, so that the bottom of the cable 3 passes between the upper and lower pinch rollers 24, then start the electric telescopic rod 22 to push the pinch roller frame 23 downward, so that the outer sides of the two pinch rollers 24 clamp the outer wall of the cable 3, then use the tool to rotate the adjusting screw 44, so as to adjust the height of the slider 2 46, so that the bottom of the outer walls of the two support rollers 49 at the top contact the top of the outer wall of the cable 3, and then rotate the adjusting screw sleeve 59 as needed, so that the screw 5 is tightened under the action of the threaded connection. 10 is controlled, thereby adjusting the height of the two guide rollers 1 54 on the bracket three 51, so that the cable 3 is at the same height on the two pinch rollers 24, the two groups of support rollers 49 and the two guide rollers 1 54, and the detection device can be started to make the motor 26 rotate the hexagonal rod 27, drive the worm sleeve 29 and the worm 211 to rotate, and drive the pinch rollers 24 on the upper and lower worm wheels 212 to rotate in opposite directions, so that the cable 3 in the middle of the two pinch rollers 24 can be pinched and sent. While the cable 3 is being pinched and sent, the cooperation between the detection probe 42 and the detector body 41 is adopted to detect the cable 3 passing through the part between the two support rollers 49 at the bottom to detect whether there is a broken core inside the cable 3.
