A grounding wire leakage detection system based on RFID

technical field

The utility model relates to the field of electronic technology, in particular to an RFID-based grounding wire leakage detection system.

Background technique

Ensuring the safety of electric power production is the most basic work requirement of electric power companies. During the construction of high and low voltage line equipment, abnormal currents from the power grid or client terminals are often connected to the power grid, posing a threat to the health of power workers. In this special case, the grounding wire can discharge unknown currents and charges to the ground, causing instantaneous short-circuit tripping of the line, ensuring the personal safety of construction workers. Therefore, the integrity of the ground wire is particularly important.

At present, the leakage of grounding wires in my country's electric power construction process mainly relies on manual inspections by inspectors. Due to the constraints of various factors such as climate conditions, environmental factors, personnel quality and sense of responsibility, the quality and availability of inspections cannot be guaranteed. Moreover, sometimes there will be overlapping grounding lines between construction units, between operation groups, or between the jurisdiction of dispatching, and it is impossible to perform their respective safety responsibilities and implement safety measures separately. At the same time, the reflected information cannot be timely fed back and counted, resulting in defects that cannot be processed in time, hidden dangers that cannot be discovered in time, and resulting in equipment failure or the safety of personnel on the construction site. In addition, it is difficult to effectively supervise inspectors using traditional inspection management methods, and equipment accidents caused by inadequate inspections are not uncommon.
