APPARATUS FOR SEARCHING A ELECTRIC LEAKAGE POINT ON BURIED CABLE AND THE METHOD

摘要

The present invention is buried in the ground, but the ground leakage line is generated by the break point of the cable; A transmitter having a pulse generator for generating a high voltage pulse signal and applying the same to the earth leakage line, a pulse emission line connecting the pulse generator and the earth leakage line, and a ground rod connecting the pulse generator and the earth; And a detection frame having a shape of a substantially '∩' shape having a plurality of probes directly contacting the ground in order to sense an electric current emitted from the pulse generating device to the ground through an earth leakage point of an earth leakage line, and from the ground In order to facilitate the capture of the leakage current is installed on the lower end of the probe, the conduction member is moistened with the accelerating solution in contact with the ground, the earth leakage detection device is installed in the center of the upper end of the detection frame for detecting and amplifying the leakage current, and the Installed in the ground fault detecting device, the slope of the guideline is changed according to the direction and intensity of the current flowing through the probe, and has a measuring system for indicating the direction of the ground fault point. In this case, force the high-voltage pulse current to flow into the earth leakage line, and then detect the current leaking to earth through the earth leakage point to correct the earth leakage point. As identified by finding the exact leakage position without rip and replace a cable short circuit is suspected to repair only the leakage site provides a short circuit that underground exploration apparatus and method by which to reduce the physical, temporal loss.
