Transformer excitation device based on second harmonic component attenuation characteristic

The utility model discloses a transformer excitation device based on secondary harmonic component attenuation characteristics, which relates to the field of transformer excitation and comprises an exciter and a terminal accommodating mechanism arranged on the back of the exciter. The terminal storage mechanism comprises a miniature electric push rod, a wiring terminal, a main transmission frame, a main pulley, a main sliding rail, an auxiliary sliding rail, an auxiliary pulley, an auxiliary rotating frame, a transmission plate, a protection plate and a movable shaft. A miniature electric push rod is started to pull a wiring terminal, a main pulley is driven by a main transmission frame to slide and contract on a main sliding rail, while the wiring terminal contracts and slides, a protection plate back transfer plate drives an auxiliary pulley to slide on an auxiliary sliding rail below the wiring terminal through an auxiliary rotating frame, and after the auxiliary pulley slides to one end of the auxiliary sl
