The invention relates to a power box, in particular to a movable multifunctional maintenance power box, belonging to the field of power distribution equipment. The movable multifunctional maintenance power box comprises a box body (2), wherein pulleys (4) are arranged at the bottom of the box body (2); an incoming cabinet door (7) and an outgoing cabinet door (9) are arranged at the front and back ends of the box body (2) respectively; an incoming panel (5) is arranged close to the incoming cabinet door (7) end inside the box body (2); an outgoing panel (8) is arranged close to the outgoing cabinet door (9) end inside the box body (2); ground terminals (6) are arranged on the incoming cabinet door (7) and the outgoing cabinet door (9). The movable multifunctional maintenance power box can be operated safely even under the severe weathers of rain and snow, and the incoming cabinet door and the outgoing cabinet door can be closed to prevent dust and rain water from entering after power supply wiring is completed. Meanwhile, any naked conductor and conductive tip cannot be seen under the condition that the incoming cabinet door and the outgoing cabinet door of the maintenance power box are opened and closed, so that safety and reliability are ensured, and the structure is simple and reasonable.
