AI Technical Summary

Technical Problem

Existing arc fault protection monitoring devices have low monitoring sensitivity, making it difficult to accurately locate the fault location. Furthermore, the monitoring response of temperature sensing cables is delayed and easily affected by ambient temperature, which may lead to the spread of fire.

Method used

A multi-dimensional monitoring method is adopted, using ultraviolet and ultrasonic sensors to detect ultraviolet radiation and ultrasonic signals generated by electric arcs. A bandpass filter is used to remove noise, and the signal is quantified and analyzed through a communication component. The circuit breaker automatically cuts off the power supply, and fire extinguishing and alarm components are used for timely processing.

Benefits of technology

It enables precise location and timely response to arc faults, preventing fires, ensuring electrical safety, and enhancing the practical value of the device.
