Low-voltage draw-out switch cabinet

The utility model discloses a low-voltage draw-out switch cabinet comprising a cabinet body. A pedestal is disposed on the bottom of the cabinet and is provided with a plurality of blind holes. Bottom damping blocks are inlaid in the blind holes and correspond to top damping blocks connected with the bottom of the cabinet body. A top cover is arranged on the top of the cabinet body and is composed of a top plate and a bottom plate. An airflow channel is arranged between the top plate and the bottom plate. The top plate and the bottom plate are in an inverted V shape. A fan penetrates the center of the bottom plate. Two-stage damping is performed on the cabinet body by the bottom damping blocks and the top damping blocks. The airflow channel is formed by the top plate and the bottom plate which are in the inverted V shape and which are disposed in the top cover. The fan enables internal air circulation so as to prevent heat accumulation and effectively protect internal electronic elements. The interior of the switch cabinet is divided into a bus region, an electrical equipment region, and a cable region which are separated by steel plates such that normal operation of a line is guaranteed and that a fault range can be effectively prevented from expanding.
