Description

Technical Field

[0001] This invention relates to the field of leakage current detection technology, and in particular to a distributed leakage current detection system and method. Background Technology

[0002] Currently, in modern power systems, leakage problems not only lead to the waste of electricity, but may also cause serious consequences such as damage to electrical equipment and electric shock injuries or deaths. Therefore, it is particularly important to conduct comprehensive leakage detection on power supply lines, and leakage detection of street light power supply lines is one of them.

[0003] However, in the traditional leakage detection of street light power supply lines, leakage protection switches are generally installed in cabinets to quickly determine whether there is leakage in a certain branch and to conduct preliminary screening of leakage faults. However, because street light lines are exposed to the outside for a long time, they are susceptible to aging and external damage. Multiple lights or multiple cable segments in the same branch may leak at the same time. The leakage detector installed in the box can only detect leakage in a certain branch. For complex and distributed power networks, this centralized detection method has many limitations. It cannot locate which specific street light or which line segment is leaking. When troubleshooting, each light needs to be tested, which is time-consuming and labor-intensive.

[0004] Therefore, in order to overcome the above-mentioned defects, the present invention provides a distributed leakage current detection system and method. Summary of the Invention

Secondly, the collected electrical-related data is analyzed to quickly and accurately locate existing leakage areas. Simultaneously, the leakage status of these areas can be assessed to understand the specific leakage situation. Finally, based on the location results and leakage status assessment results, alarm and data recording operations are performed.
