Title:
NON-GROUNDING ELECTRIC LEAKAGE PREVENTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/009634
Kind Code:
A1
Abstract:
A non-grounding electric leakage prevention device is disclosed. The present non-grounding electric leakage prevention device comprises: an input terminal unit including a first input terminal and a second input terminal; an output terminal unit including a first output terminal and a second output terminal; an electromagnetic wave receiving unit, which is arranged so as to be adjacent to the input terminal unit and receives electromagnetic waves emitted from an input terminal, between the first input terminal and the second input terminal, electrically connected with a phase voltage terminal; a terminal polarity fixing unit, which is arranged between the input terminal unit and the output terminal unit, and determines a connection relation between the first input terminal and the second input terminal and between the first output terminal and the second output terminal according to a control signal received from the electromagnetic wave receiving unit, such that the first output terminal is electrically connected with a neutral terminal and the second output terminal is electrically connected with the phase voltage terminal; a connection terminal unit including a body unit made of an insulator, and a first connection terminal and a second connection terminal, which are arranged to be electrically insulated by being spaced from each other exposed to an upper surface of the body unit and allow the first output terminal and the second output terminal to be respectively and electrically connected to a load; and an electric leakage prevention conductor which is not electrically connected to the second connection terminal electrically connected with the phase voltage terminal but is electrically connected to the first connection terminal electrically connected with the neutral terminal, and which is arranged near the second connection terminal. Therefore, when an electric device is submerged, a flowing leakage current is reduced so as to prevent electrical shock and, furthermore, the generation of a leakage current between a phase voltage terminal and a ground terminal is prevented, and a phenomenon in which a circuit of the electric leakage prevention device is tripped can be prevented.
