Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings: the present invention aims to solve the problem that the main transformer gap protection malfunctions due to the mismatch between the main transformer gap protection and the line automatic reclosing. On the basis of the original gap protection configuration, the gap overvoltage protection and gap overcurrent protection are classified and considered. For those that meet the gap overvoltage action conditions, the outlet will be directly protected after a time delay. For those that meet the gap overcurrent action condition, the automatic reclosing signal is introduced to make a matching judgment on the relationship between the two; the present invention uses the gap protection device 5 to realize the matching of gap protection and automatic reclosing, and designs different action logics respectively.
