Description

technical field [0001] The invention relates to the field of communication cable detection, in particular to a mine communication cable tester. Background technique [0002] In the current industrial and mining fields, multi-core communication cables are often used for short-distance transmission of electrical energy and control signals. The on-off of the wire core in the communication cable and the insulation resistance between the wire cores are the two most important factors to evaluate whether it meets the index. At present, most of the multimeters are used to measure the on-off of the wire cores, and the high-voltage megohmmeter is used to detect the insulation resistance between the wire cores one by one. Depending on the technical level and work experience of the inspectors, detection errors often occur, which brings potential hidden dangers to the personal safety of underground workers and the development of enterprises. Contents of the invention [0003] The tec...
