Description

Technical Field

[0001] The utility model relates to a complex system of parallel cabinets, in particular to a complex system cabinet based on convenient wiring. Background Art

[0002] In the electronic power industry, the protection of complex system cabinets, cable layout and electromagnetic compatibility have always been common problems in the industry. In addition to complex circuits, high power, and a large number of components, complex systems also have complicated lines. This is because a complex system must be connected in parallel cabinets, and parallel cabinets will inevitably bring a large number of cables, which makes the cabinet electromagnetic environment complex, and often causes device interference due to the electromagnetic environment, which in turn affects the performance of the equipment. At the same time, high-power conversion also causes an increase in the number of cables, and bulky cables bring many assembly problems. Numerous cables often need to be inserted back and forth between cabinets, and the insertion of cables will inevitably require holes and grooves to be opened on the cabinets. The electromagnetic environment and protection requirements of complex systems are generally more stringent. In order to meet the protection and electromagnetic compatibility requirements of the cabinets, some sealing devices are needed to fill the gaps (such as stuffing boxes); or sealing processes are used to treat the gaps (such as filling glue, mud, paint, etc.).

[0003] At present, there are several ways to wire complex system cabinets:

[0004] Method 1: All cables are routed on the top of the cabinet. Route on the top is convenient for external interface connection, but it also has the following disadvantages: on the one hand, it has high requirements for cabinet top protection design and is not convenient for maintenance; on the other hand, because the cables enter and exit from the top of the cabinet, the cables inside the cabinet are long, or the cables cross back and forth, resulting in coupling effects, making the electromagnetic environment complex, which in turn affects the performance of components in the cabinet.

[0005] Method 2: All cables are routed at the bottom of the cabinet. Route at the bottom is convenient for maintenance and docking, but it also has the following disadvantages: on the one hand, the cables enter and exit from the bottom of the cabinet, resulting in longer cables inside the cabinet, or the cables cross back and forth, resulting in coupling effects, making the electromagnetic environment complex, and thus affecting the performance of the components in the cabinet; on the other hand, the bottom of the cabinet needs to be raised a certain distance to meet the bending radius of the cables, which will reduce the internal space of the cabinet and affect the layout of the components.

[0006] Method 3: The cables are partially routed at the top and bottom of the cabinet, and partially inserted through the side panels of the cabinet. This wiring method combines the advantages of Method 1 and Method 2, and the wiring of the cabinet is changed to insertion through the side panels, which can effectively shorten the cable length. However, the disadvantage is that the wiring method is still relatively cumbersome, and the opening or slotting of the side panels affects the electromagnetic compatibility and protection requirements. Even if a stuffing box is installed or filled with sealant, the effect is not satisfactory. This is mainly because the gap between the cabinets is small. If a stuffing box is installed, the height of the stuffing box is not enough, and it needs to be transferred for installation, making the installation process cumbersome; if the sealant is filled, the filling material must meet both the protection requirements and the electromagnetic shielding requirements, which increases the manufacturing and installation costs.
