AI Technical Summary

Technical Problem

In the prior art, the detection efficiency of leakage switches is low and cannot meet the large-scale and efficient detection needs, resulting in an increase in the risk of false movements, refusals and safety accidents.

Method used

A safety detection method for leakage switch is provided. After receiving the preliminary detection signal through the detector, it is determined whether the initial leakage current exceeds the safety threshold. If it does not exceed, multiple analog leakage operations are performed until the leakage switch is turned off or the number of analog times is reached, and whether the reason for the disconnection is analog leakage.

Benefits of technology

It improves the safety detection efficiency of leakage switches, reduces misjudgment, ensures the accuracy of detection results, and enhances the safety and stability of the circuit.

Abstract

The invention relates to the technical field of electric leakage detection, in particular to an electric leakage switch safety detection method and an intelligent detector. The method comprises the following steps: after receiving a preparation detection signal of a detector, acquiring an initial leakage current detected by the detector, and judging whether the initial leakage current exceeds a safe leakage current threshold value or not; if the initial leakage current does not exceed the safe leakage current threshold value, the detector is controlled to execute multiple simulation leakage operations until the leakage switch is switched off, or the simulation leakage operation times reach the simulation times; when the electric leakage switch is switched off, judging whether the reason for switching off the electric leakage switch is simulated electric leakage; if the reason for the disconnection of the electric leakage switch is simulation electric leakage, a display interface of the detector is controlled to send out a first prompt signal, and the first prompt signal is used for displaying simulation electric leakage current in simulation electric leakage operation corresponding to the disconnection of the electric leakage switch. The safety detection efficiency of the electric leakage switch can be improved.
