The invention relates to a transformer dead-zone fault relay protection method based on rapid removal and sealed TAs. According to the method, in trip control of certain-side dead-zone faults of a transformer, three conditions are set, wherein as for the first condition, a certain-side backup protection trip outlet relay of the transformer is in an action state, and alternatively other electrical quality trip outlet relays are in action states; as for the second condition, when the first condition is met, single-pulse open protection is started for time T; as for the third condition, a certain-side A-phase or B-phase or C-phase current of the transformer reaches a starting value, and alternatively a zero-sequence current Io or a negative-sequence current I2 reaches the starting value; when the conditions are met, the certain-side transformer differential protection TA of the transformer is quitted after time delay; when any one condition is not met and alternatively after open protection lasts for the time T, the certain-side transformer differential TA of the transformer is accessed by 0s. According to the transformer dead-zone fault relay protection method, action principles are simple, reliability is high, and various voltage class dead-zone faults on all sides of the transformer can be removed rapidly.
