Description

Technical Field

[0001] The present application relates to the technical field of substation construction, and in particular to an integrated switch cabinet foundation and a substation. Background Art

[0002] The switchgear in the substation is an electrical equipment that opens, closes, controls and protects the power system during transmission, distribution and energy conversion. As one of the important components in the construction of the substation, the structural reliability of the switchgear foundation has an important impact on the long-term operation and power supply safety of the substation.

[0003] In the related art, the construction schemes of switch cabinet foundation include the following two:

[0004] 1. The power cable trench, switch cabinet foundation and control cable trench are laid out in rows. A branch trench is set at the bottom of the power cable hole at the bottom of the switch cabinet to connect with the power cable trench. A buried pipe is set at the bottom of the control cable hole at the bottom of the switch cabinet to connect with the control cable trench. However, under this method, the switch cabinet foundation, power cable trench and control cable trench are independent structures with poor integration, large floor area and wide foundation pit excavation surface. At the same time, all three need to be supported by formwork during construction. The openings at the bottom of the switch cabinet foundation and the branch trench also need to be supported by formwork one by one, which requires a large amount of fragmented formwork and takes a long time to support. In addition, there are many holes connecting the switch cabinet foundation and the cable trenches, the structural form is complex, the construction error rate is high, and the entire switch cabinet foundation has a large concrete volume and a long concrete solidification period, which affects the construction period.

[0005] 2. The switch cabinet foundation adopts a box-type foundation. Multiple box-type foundations are spliced ​​together to form the switch cabinet foundation. Through the cable threading holes opened on the box-type foundation, the power cables and control cables are laid in the box to match the switch cabinet. However, under this method, the power cables and control cables share the same trench, the heat generated by the power cables is not easy to dissipate, the fire prevention measures are difficult to ensure, there are many holes in the trench wall, and the fire prevention and waterproofing measures are complicated. At the same time, the power cable has a large diameter and high hardness, and a large turning radius, so it is difficult to pass through the threading holes on the box-type foundation.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0032] like Figures 1 to 3 As shown, an integrated switch cabinet foundation of an embodiment of the utility model includes a power cable trench 1 and a control cable trench 2.

[0033] Among them, the power cable trench 1 includes a first side plate 11, a top plate 12, a second side plate 13 and a first bottom plate 14 all extending in the front-to-back direction. The first side plate 11, the top plate 12, the second side plate 13 and the first bottom plate 14 are sequentially arranged to form a power cable accommodating cavity 15. The top plate 12 is used to support the switch cabinet 3, and the power cable accommodating cavity 15 is used to place the power cable.

[0034] The control cable trench 2 extends in the front-to-back direction and is used to place the control cables. The control cable trench 2 is arranged side by side on the side of the second side plate 13 in the left-to-right direction.

[0035] According to the integrated switch cabinet foundation of the embodiment of the utility model, the power cable trench 1 is used as the foundation for supporting the switch cabinet 3, and is arranged directly adjacent to the control cable trench 2, thereby realizing the combination of the two. Compared with the power cable trench, switch cabinet foundation and control cable trench arranged in flat rows in the related art, the present application omits a separate switch cabinet foundation structure, so the overall footprint is reduced, the foundation pit surface required for excavation during construction is small, and the amount of fragmentary formwork is reduced to a certain extent. In addition, after integral casting, the concrete volume of the entire switch cabinet foundation is also smaller than that of the switch cabinet foundation in the related art, and the concrete solidification period is correspondingly shortened, thereby effectively shortening the entire construction period.

[0036] Preferably, the first side panel 11, the top panel 12, the second side panel 13 and the first bottom panel 14 can be connected end to end in sequence to form a power cable accommodating chamber 15. To simplify the construction operation and ensure the supporting effect of the switch cabinet foundation, the first side panel 11, the top panel 12, the second side panel 13 and the first bottom panel 14 are perpendicular to each other.

[0037] It can be understood that the left and right direction is the width direction of the power cable trench 1 and the control cable trench 2. The power cable trench 1 and the control cable trench 2 allow the power cables and the control cables to be supplied in separate trenches. Therefore, compared with the relevant technology, the switch cabinet foundation in the present application avoids the fire safety hazards that exist when the two are laid in the same trench.

[0038] It should be noted that the power cable is laid in the power cable accommodating chamber 15 along the front-to-back direction, and the control cable is laid in the control cable trench 2 along the front-to-back direction.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, a power cable hole 16 connecting the power cable accommodating cavity 15 and the bottom of the switch cabinet 3 is provided on the top plate 12 .

[0040] A wire tube 17 is pre-buried in a portion of the top plate 12 away from the power cable hole 16 , and two ends of the wire tube 17 are respectively connected to the control cable trench 2 and the bottom of the switch cabinet 3 .

[0041] Since the top plate 12 is used to support the switch cabinet 3, and the first side plate 11, the top plate 12, the second side plate 13 and the first bottom plate 14 are sequentially arranged to form a power cable accommodating chamber 15, a power cable hole 16 is opened on the top plate 12, so that the power cable can turn in the power cable accommodating chamber 15 and then directly pass through the power cable hole 16 to supply the switch cabinet 3. At this time, there is no other spatial restriction on the power cable when turning in the power cable accommodating chamber 15, so a sufficiently large turning radius is provided for the power cable. Compared with the configuration method of the box-type foundation in the related technology, the power cable is turned after passing through the threading hole to supply the switch cabinet, the aperture of the threading hole limits the turning radius of the power cable, making it difficult for the power cable to pass through the threading hole. The coordinated design of the structure and layout of the power cable trench 1 and the power cable hole 16 in the present application effectively avoids the problem of the perforation configuration of the power cable.

[0042] The wire tube 17 can be used to guide the control cable from the control cable trench 2 to the switch cabinet 3, and it is pre-buried in the top plate 12, which facilitates the connection between the control cable trench 2 and the switch cabinet 3. There is no need to separately support the formwork to form the control cable hole during concrete pouring, which reduces the use of fragmentary formwork, reduces the formwork time and construction error rate. In addition, the power cable hole 16 and the wire tube 17 are separately arranged on the top plate 12, further avoiding mutual interference between the power cable and the control cable during the cable supply process, making it less likely for the two to have fire safety problems, and also facilitating later maintenance.

[0043] Specifically, the wire tube 17 can be made of a galvanized steel tube, and the apertures and specific layout positions of the power cable hole 16 and the wire tube 17 can be designed accordingly according to the specific specifications and applications of the switch cabinet foundation and the switch cabinet 3.

[0044] In addition, the power cable hole 16 may be provided on the top plate 12 , or may be formed by a portion of the top plate 12 facing away from the second side plate 13 being spaced apart from the first side plate 11 , which will not be elaborated here.

[0045] It can be understood that since the power cable is laid in the power cable accommodating chamber 15 along the front-to-back direction, that is, it is arranged along the extension direction of the power cable accommodating chamber 15, when it passes through the power cable hole 16 on the top plate 12 from bottom to top, the power cable first turns directly in the power cable accommodating chamber 15, and then passes through the power cable hole 16 after turning. That is to say, its turning space is the power cable accommodating chamber 15, and the turning space in the related art is a threading hole. Therefore, the power cable accommodating chamber 15 can ensure that the power cable has a sufficiently large turning radius.

[0046] like Figure 1 As shown, in some embodiments, an axilla beam 18 is connected between the top plate 12 and the second side plate 13 , and the axilla beam 18 is located on the inner surface of the corner defined by the top plate 12 and the second side plate 13 , and at least a portion of the wire tube 17 is pre-buried in the axilla beam 18 .

[0047] The design of adding axillary beams 18 improves the bearing capacity of the top plate 12 to ensure the supporting reliability of the power cable trench 1 for the switch cabinet 3, and burying the wire tube 17 in the added axillary beams 18 can reduce the impact on the structural strength of the top plate 12 itself. At the same time, the added axillary beams 18 are arranged at the corner of the top plate 12 and the second side plate 13, and the wire tube 17 is pre-buried in this position, which also saves the use length of the wire tube 17 to a certain extent and reduces the cost.

[0048] Specifically, in order to further prevent the external environment from corroding the wire tube 17 , the wire tube 17 can be completely embedded in the axillar beam 18 , and on the same projection plane, the axis of the wire tube 17 and the hypotenuse of the axillar beam 18 can be parallel.

[0049] It can be understood that compared with other positions of the top plate 12, the top plate 12 at the position of the added side beam 18 has its structural strength enhanced due to the added side beam 18 structure. Therefore, burying the wire tube 17 at this position can not only reduce the impact of the pipe on the structural strength of the top plate 12, but also use a shorter length of the wire tube 17 to achieve the connection between the control cable trench 2 and the switch cabinet 3, while reducing the use of control cables and saving costs.

[0050] like Figure 1 As shown, in some embodiments, the top plate 12 is used to support multiple switch cabinets 3 arranged along the front-to-back direction, and multiple power cable holes 16 and wire tubes 17 are provided on the top plate 12 along the front-to-back direction, and the power cable holes 16 and wire tubes 17 correspond one-to-one to the switch cabinets 3.

[0051] The switch cabinet foundation can support multiple switch cabinets 3 at the same time, and each switch cabinet 3 is supplied with cables by the corresponding power cable holes 16 and wire tubes 17, so it has good independence.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the top plate 12 is pre-embedded with embedded parts 19 for connecting with the switch cabinet 3 .

[0053] Specifically, the switch cabinet 3 may be connected to the embedded component 19 by welding, but is not limited to welding. The embedded component 19 can ensure the reliable arrangement of the switch cabinet 3 on the power cable trench 1.

[0054] like Figure 3 As shown, in some embodiments, there are multiple embedded parts 19 , and the multiple embedded parts 19 are arranged in an array on the top plate 12 .

[0055] Specifically, multiple embedded parts 19 can be pre-buried on the top plate 12 at intervals along the left and right directions. The number and arrangement of embedded parts 19 should not affect the layout of the power cable holes 16 and the wire tubes 17, and should be calculated and designed based on the specific specifications of the top plate 12 and the actual supporting connection strength.

[0056] like Figure 1 As shown, in some embodiments, the first side plate 11, the top plate 12, the second side plate 13, the first bottom plate 14 and the control cable trench 2 are reinforced concrete components that are cast in one piece.

[0057] The first side plate 11, the top plate 12, the second side plate 13, the first bottom plate 14 and the control cable trench 2 are designed to be an integrally cast reinforced concrete member, which not only ensures the structural strength of the switch cabinet foundation and meets the force requirements, but also simplifies and facilitates the construction of the entire switch cabinet foundation, so that it can be integrally cast at the construction site, thereby improving construction efficiency.

[0058] like Figure 1 As shown, in some embodiments, the control cable trench 2 includes a second bottom plate 21 and a third side plate 22 extending in the front-to-back direction, the second bottom plate 21 has a first end and a second end opposite to each other in the left-to-right direction, the first end of the second bottom plate 21 is connected to the second side plate 13, the second end of the second bottom plate 21 is connected to the third side plate 22, and the second side plate 13, the second bottom plate 21 and the third side plate 22 together constitute a control cable accommodating chamber 23.

[0059] The wire passing tube 17 is communicated with the control cable accommodating chamber 23 .

[0060] The control cable trench 2 is formed by the cooperation of the second side plate 13, the second bottom plate 21 and the third side plate 22, which not only realizes the integration between the power cable trench 1 and the control cable trench 2, making the two have good integration, but also makes the power cables and the control cables arranged in separate trenches. At the same time, the power cable trench 1 and the control cable trench 2 share a side wall, which also saves costs.

[0061] Specifically, the second side plate 13 and the third side plate 22 may both be vertically connected to the second bottom plate 21 .

[0062] like Figures 1 to 3 As shown, in some embodiments, the integrated switch cabinet foundation further includes a plurality of cover plates 4 for closing the control cable trench 2 .

[0063] A first positioning portion 121 extending along the front-to-back direction is formed on the top plate 12, and a second positioning portion 221 extending along the front-to-back direction is formed on the third side plate 22 corresponding to the first positioning portion 121. A positioning groove is formed between the first positioning portion 121 and the second positioning portion 221, and multiple cover plates 4 are arranged in sequence along the front-to-back direction and fit into the positioning groove.

[0064] The cover plate 4 can seal the control cable trench 2 to reduce the impact of the external environment on the control cables therein and ensure the service life of the control cables. The positioning grooves facilitate the installation of the cover plate 4 on the control cable trench 2.

[0065] Specifically, a plurality of cover plates 4 are arranged adjacent to each other in sequence.

[0066] like Figures 1 to 3 As shown, a substation according to an embodiment of the utility model includes the above integrated switch cabinet foundation.

[0067] The technical advantages of the substation according to the embodiment of the utility model are the same as the technical advantages of the above-mentioned integrated switch cabinet foundation, which will not be repeated here.

[0068] Now, combined with the specific structure of the integrated switch cabinet foundation, the construction process is explained as follows:

[0069] 1) Excavate the foundation pit according to the design specifications of the switchgear foundation;

[0070] 2) Lay out the steel frame of the power cable trench 1 and the control cable trench 2 in the foundation pit and support the formwork, tie the galvanized steel pipe to the corresponding position of the steel frame, and fix the embedded parts 19;

[0071] 3) Use concrete to cast the steel skeleton of the power cable trench 1 and the control cable trench 2;

[0072] 4) After the concrete strength reaches the designed strength, remove the formwork;

[0073] 5) Arrange a plurality of switch cabinets 3 in sequence along the front-to-back direction on the top plate 12, and connect the switch cabinets 3 to the embedded parts 19 by welding;

[0074] 6) Lay the power cable in the power cable accommodating chamber 15, and the control cable in the control cable accommodating chamber 23, and make the power cable pass through the power cable hole 16 to connect to the switch cabinet 3, and the control cable pass through the wire tube 17 to connect to the switch cabinet 3;

[0075] 7) Multiple cover plates 4 are sequentially placed in the positioning groove along the front-to-back direction to close the control cable trench 2;

[0076] 8) Backfill the excavated foundation pit to complete the construction of the switch cabinet foundation.
