RESISTIVE LEAKAGE CURRENT DETECTION AND DIPLAY APPARATUS, LIGHTING APPLIANCE BUILT-IN RESISTIVE LEAKAGE CURRENT DETECTION AND DISPLAY APPARATUS, AND RESISTIVE LEAKAGE CURRENT MANAGEMENT SYSTEM FOR LIGHTING APPLIANCE}

The present invention detects and displays a resistance leakage current of a wiring circuit integrated fluorescent lamp, a metal duct and trunking to inform the outside, and a light luminaire, a metal duct or a trunking to have an earth leakage alarm function to alert and cut off a short circuit. The present invention relates to a resistive leakage current detection and display device installed in a circuit, an integrated lighting circuit having a wiring circuit having a resistance leakage current detection, a display and an earth leakage alarm function, and a resistive leakage current management system to which the lighting light fixture is applied.

Electricity is a clean energy that is easy to use and manage. It is an essential energy source in modern society.

However, a large part of the source of fire in the city is electricity, and the cause of such electric fire is leakage current.

Circuit breakers that detect leakage current and control the current according to the leakage current have been installed and used for a long time.

In general circuits of electrical equipment, the leakage circuit breaker protects the general wiring circuit when the leakage current exceeds 30mA, and in the power circuit, the leakage circuit breaker protects the power wiring circuit when the leakage current exceeds 50mA.

Leakage current is the cause of fire, but more accurately resistive leakage current.

The leakage current causes the resistive leakage current Igr and the capacitive leakage current Igc to flow in the wiring circuit as the sum of the electrical vectors. In fact, the leakage current leading to the fire is the resistive leakage current Igr.

In general, the interrupting circuits cut off only the leakage current, and thus, the electric interruption management by the accurate leakage current determination is often not performed.

Capacitive leakage current (Igc) is inevitably generated in devices such as fluorescent lamps, computers, refrigerators, and washing machines, and the circuit breaker is frequently switched off even though there is no particular abnormality in the circuit. As a result, the user may remove or bypass the ground fault breaker, and in the event of a fire, loss of life and property may occur.
