Problems solved by technology
[0002] At present, it is very easy to roughly measure the distance in the cable fault test. If the DZY tracker host is used for rough measurement, it usually only takes a few minutes to measure the rough distance from the fault point to the test end, and the rough measurement error generally does not exceed 10. meters, therefore, rough measuring distance is no longer the main contradiction in finding faults, and the problem of precise point determination has become the main contradiction in fast fault finding, that is, specific pointing is the most critical step in cable testing, and now more and more Most of them use cross-linked cables, and most of the faults of cross-linked cables are closed faults. The discharge sound at the fault point is often almost the same loudness at a distance of more than ten meters or even tens of meters, which brings great difficulties to the fixed point. , relying on the traditional listening method and the swing of the mechanical meter to judge the fault point obviously cannot meet the test requirements.
Moreover, the components of the existing detection device are mostly connected by wires, which is not easy to recycle and easily causes equipment damage
