Problems solved by technology
At present, the power cable fault detector is usually used to detect the fault point of the power cable. However, when using the fault detector for detection, the maintenance personnel need to hold the fault detector along the line to detect, which is not only time-consuming and laborious, but also often leads to detection errors. In some cases, there may even be personal danger accidents

The invention discloses a power cable fault detection method. The method comprises the following steps: collecting line data through a detection mechanism arranged on a high-voltage line and the detection mechanism arranged on a low-voltage line, and sending the line data to a remote monitoring center through a data collection device, wherein the remote monitoring center analyzes and processes theline data so as to discover the line fault in time; the overhauling processing is convenient, the overhauling efficiency is improved, and the personal safety is guaranteed. The conversion efficiencyof a transformer can be quickly detected through the detection mechanisms arranged at the incoming line and outgoing line of the transformer at the same time, the aged and faulted transformer can be changed in time, the electric energy waste is avoided, and an aim of energy conservation and emission reduction is reached.
Description
technical field [0001] The invention relates to the technical field of power transmission, in particular to a power cable fault detection method. Background technique [0002] After the power cable is installed and used, sometimes there will be a cable fault, resulting in the failure of normal power supply. Since the power cables are installed together in groups, when a power cable fails, it is necessary to find out the failed power cable from the group of power cables for processing. At present, the power cable fault detector is usually used to detect the fault point of the power cable. However, when using the fault detector for detection, the maintenance personnel need to carry the fault detector along the line to detect, which is not only time-consuming and laborious, but also often leads to detection errors. In some cases, even personal danger accidents may occur. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies o...
