Title:
LEAKAGE CURRENT CUTOFF SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/204332
Kind Code:
A1
Abstract:
A leakage current cutoff system according to the present invention comprises: a first cable and a second cable which are connected between a connection part to which electronic equipment is connected and a power distribution part, and which act as a neutral line and a phase power line; a ground line mutually connecting an auxiliary ground portion provided at the connection part and a main ground portion provided at the power distribution part; a first connection line having one side connected to the first cable, and having the other side connected to the ground line so that the first cable is connected to the ground line; and a second connection line having one side connected to the second cable, and having the other side connected to the ground line so that the second cable is connected to the ground line, wherein, if a leakage current occurs in the connection part, the leakage current flows in the direction from the auxiliary ground portion to the main ground portion along the ground line, the leakage current flowing along the ground line is introduced to the first cable and the second cable through the first connection line and the second connection line so as to be reused as driving power for the electronic equipment, and only the leakage current remaining after being introduced to the first cable and the second cable is safely discharged through the main ground portion.
