AI Technical Summary

Technical Problem

Existing electrical safety devices cannot effectively detect the risk of electrical fires caused by line deterioration. In particular, they cannot prevent fires caused by poor line connections or poor contact within the allowable tripping current of overcurrent circuit breakers, and they cannot distinguish between hard short circuits and normal loads, resulting in insufficient detection of fire and electric shock hazards.

Method used

By using IoT technology to measure physical quantities such as voltage and current in a line in real time, Kirchhoff's current law and voltage law are used to analyze the electrical characteristics of the line, detect line power loss and resistance, monitor abnormal signs on the line in real time, and prevent electrical fires.

Benefits of technology

It enables the early detection of line defects before electrical fires occur, reducing losses, preventing electrical fires and electric shock accidents, and improving the safety and reliability of the power system.

Abstract

The present invention relates to a technology for preventing electrical disasters by detecting abnormal signs of a power grid in advance by measuring characteristics of a line such as electric power loss and line resistance of the line. The present invention detects abnormal signs of a fire that can occur in a distribution power network by using a communication technology such as Internet of Things (IoT) technology to measure physical quantities of a line at all times in a live state at a power supply end and a load end, thereby indirectly measuring electric power loss on the line and line resistance that is a cause thereof, detecting defects of the line, and thereby detecting a fire sign.
