Residual voltage disappear when, if forward voltage disappears simultaneously, be latched it is reversed obtain electric combined floodgate, otherwise forward voltage does not disappear simultaneously
It loses, positive to obtain electric combined floodgate, unlock is reversed to obtain electric combined floodgate；
Step SS523: block switch has reversed closing locking and automatically terminates logic, when the switch in reversed closing locking is examined
Measure former electric side again it is electric, voltage-duration is greater than X runing time and residual voltage is not detected, then switch forward obtains
Electricity closes a floodgate, and unlock is reversed to obtain electric combined floodgate.
9. the adaptive type feeder automation fault handling method on the spot according to claim 1 based on region serial number,
It is characterized in that, the non-faulting region in the step SS6, which restores electricity, to be specifically included: failure upstream region restores electricity and failure
Downstream area restores electricity.
10. the adaptive type feeder automation fault handling method on the spot according to claim 1 based on region serial number,
It is characterized in that, the step SS6 is specifically included: for short trouble or high current ground fault, after Fault Isolation, failure upstream
It restores electricity and is realized by second of reclosing of substation exit breaker；If it is small current grounding fault, after Fault Isolation
The non-power loss in failure upstream is not necessarily to recovery operation；Fault down stream region restores electricity through interconnection switch unilateral side decompression time-delay closing
It realizes, the unilateral decompression time-delay closing time is the XL runing time in the step SS4；Non-faulting area segmentation switch successively obtains
Electricity closes a floodgate, and obtaining electric combined floodgate delay time is the X runing time in the step SS4.
