Problems solved by technology

[0006] The main problem faced by the existing cable line partial discharge detection technology is: how to improve the partial discharge detection sensitivity when there are many interference sources such as corona in the environment of the measurement site
[0009] To sum up, the existing technologies all use a single detection method to propose a solution for a specific fault
In the underground cable field environment, the fault phenomenon caused by various reasons may be very compli

Description

technical field [0001] The invention relates to an underground cable fault detection device, in particular to a self-propelled underground cable fault detection intelligent instrument. Background technique [0002] In the past two decades, in order to ensure the safe operation of power cables, the on-line monitoring technology for the insulation status of power cables has been greatly developed. Foreign countries, especially developed countries such as Europe, America and Japan, are in a leading position in detection methods and technologies. The insulation detection devices researched and developed by them have good application effects, and long-term online operation also provides a large number of monitoring results, which enriches the cable inspection. Criterion for insulation defects and aging. The technical fields related to the invention mainly include underground cable thermal fault detection, cable partial discharge detection, and insulation aging state detection. ...
