Anti-rotation nesting sleeve, three-phase copper bar assembly and motor equipment

The invention provides an anti-rotation nesting sleeve, a three-phase copper bar assembly and motor equipment, the anti-rotation nesting sleeve comprises a cylindrical nesting sleeve body and a protruding body arranged on one axial end face of the nesting sleeve body in a protruding manner, and the nesting sleeve body of the anti-rotation nesting sleeve can be connected in a first connecting hole of a first three-phase copper bar in a sleeving manner; the protruding body of the anti-rotation nesting sleeve can protrude out of the first three-phase copper bar and abut against the second three-phase copper bar, in the process that the first three-phase copper bar and the second three-phase copper bar are fastened through the bolt, the pressure of the bolt can drive the protruding body to be embedded into the second three-phase copper bar, the anti-rotation resistance is increased, and the anti-rotation effect is improved. Therefore, the first three-phase copper bar is prevented from rotating relative to the sec
