DOUBLE-GROUND SAFETY SYSTEM CAPABLE OF IMPROVING RELIABILITY

WIPO Patent Application WO/2020/215527

A1

A double-ground safety system capable of improving the power utilization reliability. In order to avoid accidents caused by the failure of a grounding system and electric leakage of an electrical appliance, a real-time monitoring circuit is connected in a double-ground closed series loop in series, so as to control a power transmission system. Once a ground closed series loop system has an open circuit fault, an electric shock risk may occur, and the real-time monitoring circuit is deenergized, thereby resulting in an immediate automatic power supply cutoff. Therefore, a prompt of the occurrence of an imperceptible safety fault is given by the processing method of a power failure, and a reminder can be given that the safety fault has to be actively removed. The system aims to avoid causing an electric shock risk in the case that a secondary ground fault occurs again, so as to ensure the personal safety of an electricity user, and same changes a passive protection manner for a traditional electric shock protector that can only achieve a protective effect in the case where an electric shock actually needs to occur, so as to achieve de-electrification, and same also overcomes the defect that the electric shock protector has a blind protection region.
