The invention discloses a high-voltage electrification sweeping machine for automatic power transformation equipment. The high-voltage electrification sweeping machine comprises a machine base, a track, a drive motor, an air cylinder fixed to the machine base, a support rod, an adjusting rod, a sweeping brush and a telescopic rod connected between the support rod and the adjusting rod. The air cylinder can adjust the height of the support rod so that different height positions of a high-voltage electrification part can be swept. The adjusting rod is obliquely hinged to the support rod, the oblique angle of the adjusting rod can be changed through stretching and contracting of the telescopic rod, the high-voltage electrification part at the special space position or with the special appearance can be swept as well, and meanwhile fine adjustment can be conducted at the vertical height. The sliding stability of the machine base on the track can be guaranteed through the arrangement of limiting clamping strips and limiting grooves, and rollover accidents are avoided; the track is an arc track or a straight track capable of being assembled and connected through connecting end plates, different arc tracks can be assembled according to the specification of high-voltage electrification parts of electrical equipment, and after assembling is finished, the sweeping machine is started and finishes automatic sweeping work according to the fixed track.
