[0003] The existing cabinet body is assembled by assembling sheet metal parts, which are of many types and are complicated to assemble. In addition, since the processing methods of various sheet metal parts are different, when assembling the cabinet body of the ring network cabinet, it is necessary to wait for all sheet metal parts to be processed before assembly can proceed, which takes too long.

[0004] There is a ring network cabinet with a common box base, which includes a first side plate, a second side plate and a transverse plate. The first side plate and the second side plate are connected to the two ends of the transverse plate, and the transverse plate is respectively located in the middle of the first side plate and the second side plate. A plurality of cable chambers are arranged side by side on the front side of the transverse plate, and adjacent cable chambers are separated by partitions. The transverse plate is respectively provided with a pressure relief port at the position of each cable chamber, and the pressure relief port is located on the side of the storage chamber and an isolation plate is provided. In the storage chamber on the rear side of the transverse plate, the pressure relief port is connected between the cable chamber and the storage chamber, and a high-voltage circuit breaker and an operating mechanism are arranged on a cable chamber.

[0005] A supporting column is also provided on the partition of the base of the ring network cabinet, and parts for the supporting column need to be provided separately.

When installing the base, the staff does not need to install the supporting column separately, which reduces the assembly time of the staff and simplifies the assembly of the base. In addition, since the supporting component is formed by bending the side panel twice, its supporting strength is stronger than that of a single bend.

[0009] In a further solution, the first side of the second isolation plate is further bent to form a third supporting component, and the third supporting component is provided with a fifth bending portion and a sixth bending portion, and the fifth bending portion is perpendicular to the sixth bending portion.

[0010] It can be seen that the second isolation plate has two bent parts to enhance the supporting strength. In addition, it reduces the parts of the supporting column and reduces the assembly time of the staff.

[0020] It can be seen that the first side plate and the lifting part are integrally formed, so that the bottom plate of the cable room does not touch the ground, and the use of parts is reduced, which is convenient for workers to assemble. The bottom plate of the cable room does not touch the ground, preventing the high-voltage circuit breaker and operating mechanism inside the cable room from getting wet.

[0021] In a further solution, the first isolation plate is provided with a pressure relief port at the location of each cable chamber.

[0022] It can be seen that when an explosion occurs in the cable chamber, the explosion pressure can be discharged from the pressure relief port. BRIEF DESCRIPTION OF THE DRAWINGS
