Intelligent feeder terminal device for power distribution network fault detection

The invention provides an intelligent feeder terminal device for power distribution network fault detection. The intelligent feeder terminal device is characterized by comprising a communication module, a fault detection module, a main control module, a data processing module and a power module; the working method of the intelligent feeder terminal device comprises detecting, acquiring, comparing, processing and analyzing, and judging faults; the intelligent feeder terminal device for power distribution network fault detection has the advantages that the outlet of a transformer substation does not need to be tripped or reclosed, instantaneous faults can be processed quickly, fault isolation and non-fault region recovery do not relay on communications, and the whole fault processing time is close to and even shorter than that of a current type fault detection mode.
