Document Type and Number:

WIPO Patent Application WO/2023/173454

Kind Code:

A1

Abstract:

Disclosed in the present invention is a power line electronic leak detection and electronic leak protection circuit, comprising a live wire, a neutral wire, and a trip coil. The live wire and the neutral wire are respectively provided with controlled switch controlled by the trip coil; the outer sides of the live wire and the neutral wire are respectively provided with shielded cables; tail ends of two shielded cables are connected to each other; shielded cable detection circuits which are respectively connected to the front ends of the two shielded cables and are used for detecting whether the shielded cables are broken are provided between the live wire and the neutral wire; and a control circuit which controls the trip coil to turn off the controlled switch when it is detected that the shielded cables are broken is connected to the shielded cable detection circuits, so as to prevent a cable core from being exposed after the shielded cables are broken, resulting in short circuit between the live wire and the neutral wire to cause a fire accident.
