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. La présente invention concerne un système de coupure de courant de fuite comprenant : un premier câble et un second câble qui sont connectés entre une partie de connexion à laquelle un équipement électronique est connecté et une partie de distribution d'énergie, et qui agissent comme une ligne neutre et une ligne d'alimentation de phase ; une ligne de masse connectant mutuellement une partie de masse auxiliaire disposée au niveau de la partie de connexion et une partie de masse principale disposée au niveau de la partie de distribution d'énergie ; une première ligne de connexion ayant un côté connecté au premier câble, et ayant l'autre côté connecté à la ligne de masse de telle sorte que le premier câble est connecté à la ligne de masse ; et une seconde ligne de connexion ayant un côté connecté au second câble, et ayant l'autre côté connecté à la ligne de masse de telle sorte que le second câble est connecté à la ligne de masse, où, si un courant de fuite se produit dans la partie de connexion, le courant de fuite circule dans la direction allant de la partie de masse auxiliaire à la partie de masse principale le long de la ligne de masse, le courant de fuite circulant le long de la ligne de masse est introduit dans le premier câble et le second câble à travers la première ligne de connexion et la seconde ligne de connexion de façon à être réutilisé en tant que puissance d'entraînement pour l'équipement électronique, et seul le courant de fuite restant après avoir été introduit dans le premier câble et le second câble est déchargé en toute sécurité à travers la partie de masse principale. 본 발명에 따른 누설전류 차단 시스템은, 전자설비가 연결되는 연결부 및 배전부 사이에 연결되어 중성선 및 상전원선의 역할을 수행하는 제1전선 및 제2전선과, 상기 연결부에 구비되는 보조접지부와 상기 배전부에 구비되는 메인접지부가 상호 연결되도록 하는 접지선과, 일측이 상기 제1전선에 연결되고, 타측이 상기 접지선에 연결되어 상기 제1전선과 상기 접지선을 연결시키는 제1연결선 및 일측이 상기 제2전선에 연결되고, 타측이 상기 접지선에 연결되어 상기 제2전선과 상기 접지선을 연결시키는 제2연결선을 포함하며, 상기 연결부에서 누설전류가 발생될 경우, 상기 접지선을 따라 상기 보조접지부에서 상기 메인접지부 방향으로 누설전류가 흐르게 되며, 상기 접지선을 따라 흐르는 누설전류는 상기 제1연결선 및 제2연결선을 통해 상기 제1전선 및 제2전선으로 유입되어 상기 전자설비의 구동 전력으로 재활용되고, 상기 제1전선 및 제2전선으로 유입되고 남은 누설전류만이 상기 메인접지부를 통해 안전하게 배출되도록 한다.
