The invention discloses a protective cover capable of bringing convenience to installation and movement of a power distribution cabinet. The protective cover comprises a protective cover unit, an installation and movement unit, limiting units, a cabinet placement cover unit and a cover door unit; the installation and movement unit is fixedly arranged on the bottom wall of an inner cavity of the protective cover unit; the limiting units are symmetrically arranged on the two sides of the installation and movement unit; the cabinet placement cover unit is fixedly mounted on the upper surface of the installation and movement unit; and openings are formed in both of the protective cover unit and the cabinet placement cover unit towards the same direction. A right trapezoid movement block used for directly assisting movement is provided for moving the power distribution cabinet; by virtue of pulleys, the cabinet can be moved in a more power-saving and convenient way; and in addition, when the right trapezoid movement block is moved out of the movement cavity, the included angle between the inclined waist surface of the block and the ground is maintained at 10-30 degrees, so that the power distribution cabinet can be directly moved to the right trapezoid movement block in a more power-saving and convenient way, thereby moving the cabinet to the cabinet placement cover and completing carrying.
