Problems solved by technology

Because the cabinet is a welded structure, not only the production cycle is long, the structural error is large, and the welding stress cannot be avoided, but also the overall size of the cabinet is large, the feudal investment of the power distribution room is large, and the installation, maintenance and repair of the main components in the cabinet are very inconvenient.
In addition, the protection level of this cabinet type is only IP2X, which is low; the reliability of the five-proof locking is poor, and the operation is difficult; the anti-corrosion performance is poor

Embodiment Construction

[0008] A middle-mounted switch cabinet, including a cabinet shell 50, and a partition 70 divides the enclosed space surrounded by the cabinet shell 50 into four rooms, wherein, the upper left of the cabinet shell 50 is provided with a busbar room 10, and the upper right of the cabinet shell 50 is provided with Relay instrument room 30, various control and protection devices, measuring components, instruments and low-voltage connection terminal blocks are installed in the relay instrument room 30, the handcart room 20 is located between the busbar room 10 and the relay instrument room 30, and cable rooms are installed in the rest of the space 40. The cabinet shell 50 and the partition 70 separating the four rooms are assembled into one body. The partition 70 is made of aluminum-zinc coated steel plate. The aluminum-zinc coated steel plate has strong anti-corrosion and anti-oxidation effects, and has a higher mechanical strength, such as figure 1 shown.

Abstract

The invention relates to an intermediate switchgear cabinet comprising a cabinet housing and a diaphragm integrating with the cabinet housing which divides the enclosure space enclosed by the cabinet housing into a busbar room, a handcart room, a relay instrument room and a cable room according to the function. The cabinet housing and the insulation diaphragm of the invention adopt assembly rather than welding, thereby avoiding welding stress. Furthermore the size of the invention is small and the installation and trial run is convenient.

Description

technical field [0001] The invention relates to a central switch cabinet. Background technique [0002] At present, the frame of the fixed AC metal-enclosed switchgear cabinet is welded by angle steel. The cabinet is divided into circuit breaker room, busbar room, cable room, relay room, etc., and the rooms are separated by steel plates. Because the cabinet is a welded structure, not only the production cycle is long, the structural error is large, and the welding stress cannot be avoided, but also the size of the cabinet is large, the feudal investment of the power distribution room is large, and the installation, maintenance and repair of the main components in the cabinet are very inconvenient. In addition, the protection level of this cabinet type is only IP2X, which is low; the reliability of the five-proof locking is poor, and the operation is difficult; the anti-corrosion performance is poor. Contents of the invention [0003] The object of the present invention is...
