A damping hinge type power distribution cabinet comprises a cabinet body and a door plate. The door plate is arranged on one side of the cabinet body. The door plate and the cabinet body form a closed rectangular cabinet after the door plate is closed. The damping hinge type power distribution cabinet further comprises stand columns and hinge mechanisms. The stand columns are arranged at four corners of the cabinet body. The door plate and the adjacent stand columns are connected by a plurality of hinge mechanisms. Each hinge mechanism includes a hydraulic cylinder, a linkage mechanism, a spring, a mounting plate and a transmission component. One hydraulic cylinder is horizontally arranged on each stand column fixing plate. A movable hydraulic rod is arranged in each hydraulic cylinder in a penetrating mode. One end of each hydraulic rod near the door plate is connected to the corresponding linkage mechanism through the corresponding transmission component. One end of each linkage mechanism is a rotating shaft, and the other end of each linkage mechanism is connected with the corresponding mounting plate through the corresponding spring. A positioning cabinet is arranged on a door plate positioning plate, and the rotating shafts are disposed in the positioning cabinet. The damping hinge type power distribution cabinet has a compact structure. The open and closed states and the opening and closing speeds of the door plate can be stabilized, so that collision between the door plate and the cabinet body is avoided.
