Technical Field

[0001] The utility model belongs to the technical field of transformer substation equipment, and in particular relates to a transformer substation cable sandwich structure. Background Art

[0002] The substation needs to use the cable mezzanine for laying cables. In the prior art, the design of the cable mezzanine in the substation is relatively simple, and there are no auxiliary facilities for cable laying in the cable mezzanine. The cable laying in the cable mezzanine is complicated, which is not conducive to cable line tracing and subsequent cable maintenance and repair. The patent document with patent announcement number CN206250581U discloses a cable mezzanine for a substation, characterized in that it includes a hollow bracket and a cable clamping and hanging mechanism, and the cable clamping and hanging mechanism is installed in the hollow bracket; the hollow bracket is composed of an upper frame and a lower frame, and the upper frame and the lower frame are connected by a number of vertical rods. The cable clamping and hanging mechanism is composed of a column and at least two beams, and the beams are arranged vertically and crosswise with the columns. Although this patent can clamp and hang cables; it improves the orderly rationality of cable distribution. However, it cannot effectively organize and fix the cables, which is not conducive to the later maintenance and repair of the cables. Therefore, a substation cable mezzanine structure is needed to solve the above technical problems. Utility Model Content

[0003] In view of the above-mentioned defects existing in the prior art, the utility model provides a substation cable sandwich structure, including a cable sandwich, the cable sandwich is in the shape of a cuboid, and a line inlet and a line outlet are respectively arranged at both ends of the cable sandwich; a plurality of partitions are evenly fixed in the cable sandwich along the direction from the line inlet to the line outlet, and a plurality of the partitions are each provided with a wire hole corresponding to each other, the wire hole is rectangular, and a wire clamping assembly is arranged in each wire hole,

[0004] The wire clamping assembly includes a bidirectional screw and two clamping plates. A sliding groove is provided on the bottom wall of the wire hole. The bidirectional screw is located in the sliding groove. The two ends of the bidirectional screw are rotatably connected to the two ends of the sliding groove through bearings respectively. One end of the bidirectional screw passes through the sliding groove and extends out of the cable interlayer and is connected to a rotating handle. The two clamping plates are symmetrically arranged on the forward thread and reverse thread of the bidirectional screw respectively. The clamping plate cooperates with the bidirectional screw thread, and the lower end of the clamping plate slidably cooperates with the sliding groove.

[0005] Preferably, a maintenance opening is provided at the top of the corresponding cable interlayer between two adjacent partitions, and a cover plate is provided at the maintenance opening. The cover plate is provided with a handle, and the cover plate can be directly opened to expose the cables in the cable interlayer during maintenance.

[0006] Preferably, a guide groove is provided on the top wall of the wire hole corresponding to the top end of the clamping plate, and the top end of the clamping plate is slidably arranged in the guide groove, thereby improving the stability of the clamping plate movement.

[0007] Preferably, an elastic buffer layer is provided on the clamping surface of the clamping plate, and the elastic buffer layer can be a rubber layer to avoid damage to the cable during the clamping process.

[0008] Preferably, a wire clamping assembly is provided at both the wire inlet and the wire outlet.

[0009] The utility model also includes other components that enable a substation cable sandwich structure to be used normally, which are all conventional technical means in the field. In addition, the devices or components not limited in the utility model, such as bidirectional screws, splints, elastic buffer layers, handles, etc., all adopt conventional technical means and conventional equipment in the field.

[0010] Working principle: The cables pass through the wire holes on each partition in turn from the cable inlet of the cable mezzanine and then out from the cable outlet. The bidirectional screw is driven to rotate by rotating the handles on each partition. Under the limiting action of the slide groove and the guide groove, the two clamping plates move toward each other along the bidirectional screw to clamp the passed cable, so that the cable can be fixed in sections with good fixing effect and high efficiency. When the cable needs to be maintained or overhauled, the cover plates can be opened in turn and the corresponding handles can be turned. The two clamping plates move back to back to loosen the fixation of the cable section, thus realizing section-by-section maintenance. The adverse effects on the cables are reduced during the maintenance process, and the efficiency and effect of the overhaul and maintenance are improved.

[0011] The beneficial effects of the utility model are as follows: the cables can be fixed in sections, with good fixing effect and high efficiency; when the cables need to be maintained or overhauled, they can be overhauled or repaired in sections, which reduces adverse effects on the cables during the maintenance process and improves the efficiency and effect of the overhaul and maintenance.
