10kV cable network feed line power distribution station fault automatic detection system

The invention discloses a 10kV cable network feed line power distribution station fault automatic detection system. By performing automatic configuration on a main distribution node consistent with a main distribution wiring mode, a cable-type fault indicator is configured on a wire-outlet cabinet on main line in order to achieve fast positioning of a main line fault. A kit-switchgear intelligent boundary breaker is configured on a branch line of a main-distribution power distribution station so as to achieve an automatic tripping-out function when a fault (such as over-current and zero sequence) happens at a user side and achieve an automatic reclosing function when the fault is removed, thereby achieving an automatic isolation and protection effect.
