Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
In the prior art, the shortcomings that relay bay other than above-mentioned expansibility difference, further includes:
Waste arrangement space.Since a rack is five templatespaces, no matter process system how many controlled device,
Even only one will also distribute a rack.Necessarily cause the waste of arrangement space.
Poor seismic behavior.Relay bay substantially XY two-dimension plane structure, Z axis are mentioned to intensity by the bent plate at edge
For rigidity is very limited.Anti-seismic performance especially Z axis is to poor.It is unable to satisfy ACP1000 generation Ⅲ nuclear power factory 0.3g safe stopping
The requirement of heap earthquake.
Degree of protection is low.Relay bay electrical component is all exposed in workshop, dust-proof, waterproof and mechanical collision it is anti-
Protecting grade is 0.Possible condensed water, dust in workshop are coped with, and collision resistance is low, is easy accidentally to be damaged.
Electro Magnetic Compatibility is poor.Relay bay electrical component is all exposed in workshop, although conventional component is to electromagnetism
It interferes insensitive, but when these equipment and digitizer are arranged together, be easy to cause the damage of digitizer.
As Figure 1-Figure 4, the utility model provides a kind of nuclear safe level logic control cabinet, opens the door including front and back
Cabinet；The interior of equipment cabinet is provided with intermediate bulkhead 11；11 two sides of intermediate bulkhead is mounted on cabling channel.Cabinet is frame
