1. A scroll compressor comprising:
a housing;
a partition plate, wherein the partition plate is provided in an interior of the housing and divides the interior of the housing into a suction space and a discharge space, wherein the partition plate is provided with a first through hole to communicate the suction space with the discharge space;
a rack located in the suction space in the interior of the housing, the rack and the partition plate being spaced apart;
a movable scroll plate movably provided on the rack;
a stationary scroll plate, wherein the stationary scroll plate is provided on the rack and cooperates with the movable scroll plate, wherein the stationary scroll plate is provided with a second through hole communicating with the discharge space; and
a pressure relief low-speed rotation structure, wherein the pressure relief low-speed rotation structure is provided on the stationary scroll plate and is configured to be capable of, in a shut down state of the scroll compressor, balance pressure in the discharge space with pressure in the suction space by allowing the second through hole to communicate with the discharge space.
