Abstract

The invention relates to the field of cable fault detection, in particular to a movable cable fault tracing device. The movable cable fault tracing device comprises a signal probe, earth current EC, a compound power amplification circuit, a voltage amplification circuit, a feedback circuit, a voltage regulator circuit and an alarm circuit. The movable cable fault tracing device has the advantages of finding breakage fault points because of frequent buckling and crimping in a movable cable quickly and effectively, protecting the whole movable cable well, and prolonging service life of the movable cable, and the breakage fault points do not need to be found by splitting the movable cable section by section. In addition, the movable cable fault tracing device has the advantages of being simple in structure, easy to operate, extremely safe, and suitable for wide application.

Description

technical field [0001] The invention relates to the field of cable fault detection, in particular to a mobile cable fault finder. Background technique [0002] In the work of electric power test, maintenance, lighting, agricultural power water pump, etc., due to the variation and change of the environment and site, it is necessary to move the construction. In this way, the required cables of tens or hundreds of meters must also be moved. In the process of shrinking and shrinking, the cables are frequently bent and curled, and the number of times of bending and curling is too many or excessive, which often causes the line to break and fail to work. However, the results obtained by testing with tools such as test pens and multimeters It's just that the power is interrupted, the transmission is not in place, and these inspections can only be carried out from the terminal interface or exposed places, and the middle is mostly plastic or rubber shielding, so it is impossible to de...
