Referring to fig. 3, the utility model provides a cubical switchboard generating line room top cap, generating line room top cap 7 includes first apron 71, and one of them looks remote site of first apron 71 sets up to the bending end 711 of bending towards generating line room 6, and bending end 711 sets up to the groove structure of inwards bending. Compared with the bus bar room top cover structure of the conventional switch cabinet shown in fig. 2, in this embodiment, the first cover plate of the original planar structure is modified, wherein one opposite end is a groove-shaped bent end bent to face the inside of the bus bar room 6, and when the bus bar room top cover 7 covers the bus bar room 6, the groove-shaped bent end 711 of the first cover plate 71 is directly clamped in the bus bar room 6, so that the installation of the bus bar room top cover is facilitated, and the rigidity of the bus bar room top cover 7 after installation is ensured.

Referring further to fig. 3, in the present embodiment, a second cover plate 72 is movably hinged to the upper surface of the first cover plate 71, and the second cover plate 72 is connected to the first cover plate 71 through four elastic columns 722; an upper vent 712 is arranged on the first cover plate, and a filter screen is arranged on one side of the upper vent 712 facing the bus chamber 6; the second cover plate 72 is sized to match the upper vent 712, and the end of the second cover plate 72 facing the upper vent 712 is correspondingly provided with louvers 7211, forming a louver opening 721.

Under normal conditions, heat generated by the components and the bus bar in the cabinet body is dissipated through the upper vent 712 and then through the louver opening 721 on the second cover plate 72. Meanwhile, a nylon fiber synthetic resin filter screen is arranged above the upper ventilation opening 712, so that dust is effectively prevented from entering the electric control cabinet. When the impact pressure of heat generated by a fault is too high, the pressure cannot be quickly released in a short time only by the louver opening 721, therefore, in the embodiment, the second cover plate 72 is further configured to move up and down along the four elastic posts 722, the second cover plate 72 can be lifted upwards by a large impact force generated by the fault, and the airflow further passes through the gap between the upper vent 712 on the first cover plate 71 and the second cover plate 72 to be released outside effectively. The pressure relief mode improves the efficiency and avoids the condition that the cabinet body cannot be outwardly relieved to cause the diffusion of faults into the cabinet. Meanwhile, the bus chamber top cover 7 can be effectively prevented from popping up due to overlarge bus chamber air pressure, personnel damage is caused, and the safety and reliability of the switch cabinet are further improved.

Referring to fig. 4, the utility model also provides a GGD low-voltage switchgear, including generating line room top cap 7 and cabinet body frame, its generating line room top cap 7 adopts foretell generating line room top cap structure. The cabinet frame comprises longitudinal beams 1 arranged on two sides, a first side cross beam 2 used for installing a bus frame 61, an inner upright post 3 and a second side cross beam 4 which is connected with the inner upright post 3 and transversely arranged. The two ends of the first side cross beam 2 are respectively welded on the longitudinal beams 1 at the two sides, so that the rigidity of the whole cabinet body structure is ensured. Two ends of the second side cross beam 4 are fixedly connected to the longitudinal beams 1 on two sides through self-locking screws 5, and the second side cross beam 4 is arranged to be multiple. The first side cross member 2 partitions the upper space of the cabinet frame into a bus bar room 6, and the inner column 3 and the second side cross member 4 partition the lower space of the cabinet frame into a cable room, a switch room, a circuit protection room, and the like.

The GGD low-voltage switch cabinet of the embodiment sets the traditional bus installation mode of the cabinet body from a penetration type to an embedded type, and the arrangement of the bus chamber top cover is convenient for the installation of the bus chamber top cover, so that the GGD low-voltage switch cabinet is suitable for the embedded type installation of the bus; and the condition that faults spread into the cabinet when the bus chamber has faults can be effectively prevented. After the cabinet body and the cabinet body are assembled, an installer only needs to open the top covers of the bus chambers of all the cabinet bodies and can embed the buses into the bus chambers in the cabinet body, and the defects that the buses are punched in the cabinet body and penetrate into the cabinet body one by one in the traditional installation mode are overcome. It is worth noting, the utility model provides a bus-bar room top cap not only is applicable to GGD low-voltage switchgear, still is applicable to low-voltage switchgear such as GCK, GBD, medium-voltage switchgear and high tension switchgear etc. and other relevant cabinet body structures.
