The invention discloses a power distribution network distributed feeder automation terminal and an adaptive detection method thereof. The terminal comprises a control module, a current acquisition module and a 4G wireless communication module. The adaptive method comprises the following steps: the current acquisition module acquires a current signal in real time; the control module judges whetherthe current is over-current or not; the control module generates a fault time synchronization signal; through the 4G communication module, fault time synchronization signals are distributed to adjacent distributed feeder automation terminals for synchronization time synchronization; and the 4G communication module is used for respectively adopting a communication quality control mechanism and a duplication name message discarding mechanism to carry out processing and judge the fault position in allusion to the problems of 4G communication delay, communication packet loss and communication multi-packet.
