Description

technical field [0001] The invention belongs to the technical field of power cable operation test, and in particular relates to a real-type test system and application method of distribution cables based on multi-dimensional digital fault inversion. Background technique [0002] During the long-term operation of the distribution cable, its insulation performance will gradually deteriorate due to the influence of its own product quality, installation and manufacturing process, and various pollutants, harmful substances, wind, sun, and other media in the environment. With the extension of the service life of distribution cables and the existence of various potential defects and problems, the problem of distribution cable failure is becoming more and more serious. Detecting and diagnosing various faults and defects that may exist in the actual operating conditions of distribution cables is of great significance for accurate discovery and timely troubleshooting to restore power ...

AI Technical Summary

Problems solved by technology

[0003] For the detection and diagnosis technology of distribution cable faults, there has been no reliable test system and evaluation method for a long time. The traditional methods generally verify the detection and diagnosis technology of distribution cable faults through theoretical calculation or simulation. Only through Theoretical analysis and computer simulation cannot consider the influence of various environmental factors in the actual operating conditions on the practical application of fault detection and diagnosis technology. At the same time, there is a huge difference between the real fault data and the data under ideal conditions, resulting in actual application results and ideal conditions. There is a huge difference in the effect under different conditions, which will eventually cause missed diagnosis and misdiagnosis and substantial economic losses.
