Description

Technical Field

[0001] This invention belongs to the technical field of substation protection and control equipment upgrade and renovation, specifically relating to a method for the overall installation and displacement of substation protection and control upgrade and renovation panels. Background Technology

[0002] Substations requiring upgrades are generally old, with aging equipment, cramped protection rooms, and complex environments. Current upgrade methods involve dismantling and replacing the old protection control panels one by one, requiring a power outage for each panel replacement. This results in numerous and prolonged outages, severely impacting production and daily life in the affected areas, and affecting power generation for the owners of the substations. To minimize these issues during upgrades, the process must be time-constrained, with minimal power outages and, in special cases, uninterrupted operation. This necessitates ensuring the continued operation of existing protection control panels, minimizing power outages for each new device, and maintaining power supply to unaffected areas. Once the old and new equipment are operational, the old protection control panels and cables are removed, and the new equipment is moved from the temporary steel frame to the permanent foundation steel, completing the upgrade. Summary of the Invention

[0003] This invention provides a method for the overall installation and displacement of substation protection and control upgrade and renovation panels. The purpose is to provide a method for the overall displacement of panels that is simple to construct in complex environments, has low cost, and can minimize the impact of construction on production, daily life, and power supply.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A method for the overall installation and displacement of substation protection and control upgrade and renovation panels includes the following steps.

[0006] Step 1: Construct a temporary transitional overhead steel frame foundation;

[0007] Step 2: Erect multiple protection control panels to be replaced on a temporary transition overhead steel frame foundation, with the back of the protection control panels to be replaced facing the foundation channel steel of the permanent protection panel;

[0008] Step 3: Connect the adjacent protection control panel cabinets to be replaced;

[0009] Step 4: Remove all original cables from the cable brackets and place them on both sides of the bottom of the cable trench;

[0010] Step 5: Repair or replace the cable brackets;

[0011] Step 6: Place the control cables to be laid on the repaired or replaced cable brackets, and then connect, verify, and debug the control cables to be laid to the protection control panel to be replaced.

[0012] Step 7: De-energize and take out the operation of the original protection panels one by one, and put the corresponding protection control panels to be replaced into operation one by one, until all the original protection panels in the entire row are taken out and all the protection control panels to be replaced are put into operation.

[0013] Step 8: Remove the entire row of existing protection panels and clean and repair the cable trench;

[0014] Step 9: Connect and debug the multiple protection control cabinets to be replaced on the temporary transition overhead steel frame foundation, and then move them as a whole to the cleaned foundation channel steel of the permanent protection cabinet through the temporary transition overhead steel frame foundation.

[0015] The aforementioned overhead steel frame foundation is a linear integrated structure consisting of multiple control cabinet seats with an operating space at the bottom; each control cabinet seat includes a base and a slide rail; the slide rail for moving multiple protection control panels to be replaced into the cable trench as a whole is fixedly connected to the rear side of the base facing the cable trench.

[0016] The platform is a rectangular frame consisting of four columns, two upper crossbeams, two lower crossbeams, one upper purlin, and two lower purlins, with an open rear top. The two upper crossbeams, two lower crossbeams, one upper purlin, and two lower purlins are all fixedly connected to the adjacent columns, and one upper purlin is horizontally connected to the top of the two columns on the front side.

[0017] It also includes a detachable purlin; the detachable purlin is horizontally arranged and detachably connected to the top of the two columns on the rear side; the detachable purlin is made of angle iron.

[0018] The columns, upper crossbeam, lower crossbeam, upper purlin, lower purlin, and slide rails are all made of angle iron.

[0019] The length of the column is 18-30cm.

[0020] The base also includes multiple diagonal braces; the multiple diagonal braces are respectively fixedly connected to the left and right sides and the front.

[0021] The slide rail includes two sets of slide rails; the two sets of slide rails are respectively fixedly connected to both sides of the rear side of the base.

[0022] Each set of slide rails is an integral structure of a right triangle made of three angle irons; the slide rail is set perpendicular to the rear side of the base, and the height of one right-angled side is the same as the height of the base, and the right-angled side is fixedly connected to the rear side of the base.

[0023] The connection between the top of the slide rail and the top of the base is arc-shaped.

[0024] Beneficial effects:

[0025] (1) The overall installation displacement of the substation protection and control upgrade and renovation panel using the present invention not only has a short power outage time and low cost in the relevant area, but also is simple to operate and is not limited by complex and narrow terrain.

[0026] (2) The overall installation displacement of the substation protection and control upgrade panel using the present invention will not cause the problem of old and new cables to become tangled and difficult to clean.

[0027] (3) The overall installation displacement of the substation protection and control upgrade panel can be carried out by using the present invention. While replacing the old panel, the cable trench and its internal aging equipment can also be painted and repaired, laying the foundation for the continuous and stable operation of the substation.

[0028] (4) The use of temporary transition overhead steel frame foundation in this invention not only makes it convenient to connect, test and move multiple protection control cabinets to be replaced as a whole, but also the temporary transition overhead steel frame foundation has a simple structure, is easy to obtain materials, has a low cost and can be reused.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] according to Figures 1-5 The method for overall installation and displacement of substation protection and control upgrade and renovation panels, as shown, includes the following steps:

[0040] Step 1: Construct a temporary transitional overhead steel frame foundation;

[0041] Step 2: Erect multiple protection control panels 11 to be replaced on a temporary transition overhead steel frame foundation, with the back of the protection control panels 11 to be replaced facing the foundation channel steel 10 of the permanent protection panel;

[0042] Step 3: Connect the adjacent protection control panel 11 to be replaced;

[0043] Step 4: Remove all original cables from the cable brackets and place them on both sides of the bottom of the cable trench;

[0044] Step 5: Repair or replace the cable brackets;

[0045] Step 6: Place the control cable 9 to be laid on the repaired or replaced cable bracket, and then connect the control cable 9 to the protection control panel 11 to be replaced, and then connect, verify and debug it.

[0046] Step 7: De-energize and take out the operation of the original protection panels one by one, and put the corresponding protection control panels 11 to be replaced into operation one by one, until all the original protection panels in the row are taken out and all the protection control panels 11 to be replaced are put into operation.

[0047] Step 8: Remove the entire row of existing protection panels and clean and repair the cable trench;

[0048] Step 9: Connect and debug the multiple protection control cabinets 11 to be replaced on the temporary transition overhead steel frame foundation, and then move them as a whole to the cleaned foundation channel steel 10 of the permanent protection cabinet.

[0049] In practical use, the technical solution of this invention is used to carry out the overall displacement of the protection and control panel to be replaced in the substation protection and control upgrade and renovation. This not only results in short power outage time and low cost in the relevant areas, but also simple operation and is not limited by complex or narrow terrain.

[0050] The overall displacement of the substation protection and control cabinets using this invention avoids the problems of old and new cables becoming tangled and difficult to clean. Furthermore, while replacing the old cabinets, it also allows for the painting and repair of cable trenches and related aging equipment inside, laying the foundation for the continuous and stable operation of the substation.

[0051] The use of an overhead steel frame foundation in this invention not only facilitates the connection, testing, and overall movement of multiple protection control cabinets to be replaced, but also makes the overhead steel frame foundation simple in structure, easy to obtain materials, inexpensive, and reusable.

[0052] Example 2:

[0053] according to Figures 2-4 The method for overall installation and displacement of substation protection and control upgrade and renovation panels shown differs from Embodiment 1 in that: the overhead steel frame foundation is a one-piece structure with an operating space at the bottom, consisting of multiple control cabinet seats; each control cabinet seat includes a base 1 and a slide rail 2; the slide rail 2, used for the overall movement of multiple protection and control panels 11 to be replaced toward the foundation channel steel 10 of the permanent protection panel, is fixedly connected to the rear side of the base 1 facing the foundation channel steel 10 of the permanent protection panel.

[0054] In practical use, the number of control panel seats set in the overhead steel frame foundation can be determined according to the number of old panels that need to be replaced during the substation protection and control upgrade.

[0055] Multiple protection control panels 11 to be replaced are placed one by one on the base 1 of the control cabinet seat. The length and width of the base 1 match the length and width of the protection control panels 11 to be replaced. Each protection control panel 11 to be replaced faces away from the foundation channel steel 10 of the permanent protection panel, so that the multiple protection control panels 11 to be replaced are arranged in a straight line according to the order after they are placed on the foundation channel steel 10 of the permanent protection panel, and the adjacent protection control panels 11 to be replaced are connected together. After each protection control panel 11 to be replaced is connected and debugged, the multiple protection control panels 11 to be replaced are moved as a whole from the slide 2 to the foundation channel steel 10 of the permanent protection panel. The whole process is simple and convenient.

[0056] Example 3:

[0057] according to Figure 2 and Figure 4 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown differs from Embodiment 2 in that: the base 1 is a rectangular frame consisting of four columns 5, two upper crossbeams 3, two lower crossbeams 4, one upper purlin 6, and two lower purlins 7, with an open upper rear section; the two upper crossbeams 3, two lower crossbeams 4, one upper purlin 6, and two lower purlins 7 are all fixedly connected to the adjacent columns 5, and one upper purlin 6 is horizontally connected to the top of the two columns 5 on the front side.

[0058] In actual use, the base 1 adopts the above technical solution. After the protection control panel 11 to be replaced is placed on the base 1, there is an operating space between the bottom of the protection control panel 11 to be replaced and the ground, which facilitates the connection and debugging of the protection control panel 11 to be replaced and the cable.

[0059] The base 1 adopts a frame structure, which is simple in structure and easy to manufacture while ensuring that it has the required load-bearing capacity.

[0060] Example 4:

[0061] according to Figure 2 and Figure 3 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown differs from Embodiment 3 in that it also includes a detachable purlin 12; the detachable purlin 12 is horizontally arranged and detachably connected to the top of the two columns 5 on the rear side; the detachable purlin 12 is made of angle iron.

[0062] In practical use, the detachable purlin 12, when the protection control panel 11 to be replaced is placed on the base 1, not only improves the load-bearing capacity of the base 1, but also makes the placement of the protection control panel 11 to be replaced more stable. When it is necessary to move the entire row of protection control panel 11 to the foundation channel steel 10 of the permanent protection panel, the detachable purlin 12 can be removed, making it easy to move the entire row of protection control panel 11 to be replaced.

[0063] The detachable purlin 12 is made of angle iron, which meets the strength requirements and is easy to source.

[0064] Example 5:

[0065] according to Figures 2-4 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown differs from Embodiment 3 in that the column 5, upper beam 3, lower beam 4, upper purlin 6, lower purlin 7 and slide rail 2 are all made of angle iron.

[0066] In actual use, the column 5, upper crossbeam 3, lower crossbeam 4, upper purlin 6, lower purlin 7 and slide rail 2 adopt a technical solution made of angle iron, which meets the strength requirements during use and is convenient to obtain materials and has a low cost.

[0067] Example 6:

[0068] according to Figures 2-4 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown is different from that in Embodiment 3 or Embodiment 4 in that the length of the column 5 is 18-30cm.

[0069] In practical use, the length of column 5 is 18-30cm, which not only facilitates the connection and testing of the lower cables of the protection control panel 11 to be replaced, but also saves costs. If the length of column 5 is too large, although it is convenient for the cable connection and testing of the protection control panel 11 to be replaced, it will cause inconvenience for the subsequent row of protection control panel 11 to be replaced. If the length of column 5 is too small, although it is convenient for the row of protection control panel 11 to be replaced, it will be inconvenient for cable connection and testing.

[0070] Example 7:

[0071] according to Figures 2-4 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown is different from Embodiment 3 in that: the base 1 also includes multiple diagonal braces 8; the multiple diagonal braces 8 are respectively fixedly connected to the left and right sides and the front.

[0072] In practical use, the diagonal braces 8 effectively enhance the load-bearing capacity of the protection control panel 11 to be replaced, preventing accidental losses caused by insufficient load-bearing capacity of the base 1. The specific number of diagonal braces 8 can be determined based on the actual weight of the protection control panel 11 to be replaced.

[0073] In this embodiment, three diagonal braces 8 are provided, and the three diagonal braces 8 are respectively fixedly connected at an angle to the rectangular frame on the left, right and front sides.

[0074] Example 8:

[0075] according to Figures 2-4 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown is different from the second embodiment in that: the slide rail 2 includes two sets of slide rails; the two sets of slide rails are respectively fixedly connected to the two sides of the rear side of the base 1.

[0076] In actual use, the slide 2 adopts the above technical solution, which can easily move multiple connected protection control cabinets 11 to be replaced in a row onto the foundation channel steel 10 of the permanent protection cabinet.

[0077] Example 9:

[0078] according to Figures 2-4 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown is different from Embodiment 8 in that: each set of slide rails is an integral structure of a right triangle made of three angle irons; the slide rail is set perpendicular to the rear side of the base 1, and the height of one right-angled side is the same as the height of the base 1, and the right-angled side is fixedly connected to the rear side of the base 1.

[0079] In practical use, the slide rail adopts the above technical solution, which can not only perform the load-bearing function well, but also facilitate the movement of multiple connected protection control panel cabinets 11 to be replaced in a row onto the foundation channel steel 10 of the permanent protection panel cabinet.

[0080] Example 10:

[0081] according to Figure 5 The method for overall installation and displacement of the substation protection and control upgrade and renovation panel shown is different from Embodiment Nine in that the connection between the top of the slide rail and the top of the base 1 is arc-shaped.

[0082] In actual use, because the connection between the top of the slide rail and the top of the base 1 adopts an arc-shaped technical solution, when multiple connected protective control panels 11 to be replaced are moved in a row to the foundation channel steel 10 of the permanent protective panel, there will be no problem of the protective control panels 11 to be replaced or the cables being scratched by sharp corners, ensuring the smooth progress of the overall displacement.

[0083] Where there is no conflict, those skilled in the art can combine the relevant technical features in the above examples according to the actual situation to achieve the corresponding technical effects. Specific details of the various combinations will not be elaborated here.
