DISTRIBUTION SYSTEM AND FAULT SEARCH/DIVIDING METHOD

摘要

A distribution system (100) is characterized by comprising a distribution transformer (110), a high voltage power distribution line network (120), and a plurality of sensor-contained switches (130) having a sensor which is located on a line of the high voltage power distribution line network and detects the line state, a plurality of remote terminal units (140) including a detected result acquiring section (142) and a switching control section (144), an information collecting section (168) which is connected to the remote terminal units through a communication network and collects the result of the detection acquired by the remote terminal units, a fault zone identifying section (170) for identifying a fault zone according to the result of the detection, and a management server (150) including a zone dividing section (172) which opens the sensor-contained switches on the power source side and load side of the fault zone to divide the fault zone.
