PROBLEM TO BE SOLVED: To provide a technique capable of detecting the accident current due to the high-resistance ground fault by targeting a plurality of structures by one feeding protection device.SOLUTION: A feeding circuit protection system includes a trolley wire 21, a rail 22, a structure 23, a feeding protection device 24 and a linkage wire 25. The linkage wire 25 is provided along the trolley wire 21 and electrically connects the plurality of structures 23 with each other. The feeding protection device 24 has one end which is electrically connected to the linkage wire 25 and the other end which is electrically connected to the rail 22. The accident current which occurs when the trolley wire 21 is brought into contact with the structure 23 is made to flow to the rail 22. One feeding protection device 24 is provided for each of the plurality of structures 23.SELECTED DRAWING: Figure 1

    【課題】1つのき電保護装置により複数の構造物を対象として、高抵抗地絡による事故電流を検出することができる技術を提供する。【解決手段】 き電回路保護システムは、電車線21と、レール22と、構造物23と、き電保護装置24と、連係線25とを備える。連係線25は電車線21に沿って設けられ、複数の構造物23を電気的に接続する。き電保護装置24は一端が連係線25に電気的に接続され、他端がレール22に電気的に接続されている。電車線21が構造物23に接触したときに発生する事故電流をレール22に流す。1つのき電保護装置24は、複数の構造物23毎に設けられている。【選択図】図1
