Description

Technical Field

[0001] This invention belongs to the technical field of design and construction of grids for main transformer oil tanks in power engineering. Specifically, it relates to a method for arranging the bottom grids of a main transformer oil tank. Background Technology

[0002] In current projects, the bottom layer grating of the main transformer oil bath is typically erected directly on angle steel, which is then fixed to the oil bath, foundation, and rectangular support sidewalls. Therefore, the layout of the bottom layer grating is crucial. Improper layout can lead to on-site secondary processing issues, unnecessary waste, and even project delays. Thus, finding a quick, efficient, and intuitive way to layout the aforementioned bottom layer grating is a pressing problem that needs to be solved. Summary of the Invention

[0003] To address the problems existing in the prior art, the purpose of this invention is to provide a method for laying out the bottom layer grid of the main transformer oil tank. This method is simple and intuitive, and can quickly and efficiently lay out the bottom layer grid of the main transformer oil tank, avoiding secondary processing on site and accelerating the construction progress.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for arranging the bottom grid of a main transformer oil sump includes the following steps:

[0006] S1: Divide the layout area:

[0007] S11: Based on the distribution characteristics of the oil pool and the main transformer foundation, the oil pool is divided into the area directly opposite the short side of the main transformer foundation, the area directly opposite the long side of the main transformer foundation, the corner area of ​​the oil pool, and the middle area of ​​the main transformer foundation.

[0008] S12: Define the area directly opposite the short side of the main transformer foundation as the first area, the area directly opposite the long side of the main transformer foundation as the second area, the corner area of ​​the oil tank as the third area, and the middle area of ​​the main transformer foundation as the fourth area, and lay out the oil tank accordingly.

[0009] S2: Deploying Key Supports: This includes the following steps:

[0010] S21: Arrange a row of key pillars in the first area, with the center line of the key pillars coinciding with the center line of the short side of the foundation.

[0011] S22: Arrange a row of key pillars in the second area, with the upper or lower edge of the key pillars in the area being flush with the extension line of the short side of the foundation.

[0012] S3: Adjust the support pillars: Arrange the support pillars in the third and fourth areas so that the center line of the support pillars coincides with the center line of the key support pillars in the first and second areas. Adjust the number of rows and columns of support pillars according to the grid specifications.

[0013] S4: Assign the supports "forward" and "reverse" properties, and make the supports arranged at intervals. This includes the following steps:

[0014] S41: Assign "forward" or "reverse" properties to key pillars in the second area. If the upper edge of the pillar is flush with the extension line of the short side of the foundation, then the pillar is assigned "reverse" property; otherwise, it is assigned "forward" property. Pillars that conform to "forward" property are defined as "forward" pillars, and pillars that conform to "reverse" property are defined as "reverse" pillars.

[0015] S42: Based on the "forward" and "reverse" nature of the key pillars in the second area, arrange "forward" and "reverse" pillars. According to the principle of arranging "forward" and "reverse" pillars alternately, deduce the "forward" and "reverse" nature of all pillars in the first area 1, the third area and the fourth area.

[0016] S5: Determine the area based on the "forward" and "reverse" properties of the pillars, and complete the layout of the grille;

[0017] S51: Extend the support edge line in the direction of the "clockwise" and "counterclockwise" arrows to the adjacent support, foundation and oil tank edge lines to form an extension line;

[0018] S52: The extension line divides the oil pool into several areas, each of which is a grid plate area. The grid layout can be completed according to the "forward and reverse" properties.

[0019] Furthermore, the supports within the oil tank are rectangular columns with uniform cross-sectional dimensions, which is a condition for the applicability of the method of the present invention.

[0020] Furthermore, in step S4, the "clockwise" and "counterclockwise" properties of the "clockwise" and "counterclockwise" columns are represented by four arrows parallel to the outer sides of the rectangular columns.

[0021] Furthermore, the four arrows of the "clockwise" column exhibit a clockwise rotation characteristic relative to the center of the support column, while the four arrows of the "counterclockwise" column exhibit a counterclockwise rotation characteristic relative to the center of the support column.

[0022] Furthermore, in step S4, the "forward" and "reverse" columns appear in pairs in the oil tank, and the total number of columns is an even number.

[0023] Furthermore, in step S2, there are two first regions, two second regions, four third regions, and four fourth regions.

[0024] Compared with the prior art, the layout method of the bottom grid of the main transformer oil sump of the present invention has the following beneficial effects:

[0025] This method only requires the reasonable arrangement of the grid supports and their "clockwise and counterclockwise" orientation to achieve simple, intuitive, fast, and efficient grid layout. The provided method for layout of the bottom grid of the main transformer oil tank effectively solves the layout problem of the bottom grid of the oil tank, avoids secondary processing on site, and helps to speed up the construction progress.

[0034] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0035] Example 1

[0036] This embodiment provides a method for arranging the bottom layer grid of the main transformer oil sump, such as... Figure 1 As shown, the process includes the following steps: dividing the layout area, arranging key pillars, adjusting the pillars, assigning "forward" and "reverse" properties to the pillars, and completing the grid layout. Specifically, it is as follows:

[0037] Based on the layout rules, this invention defines the grid support pillars as having two characteristics, one pillar having a "coordinated" property and the other a "reverse" property. These two types of pillars will be referred to as "coordinated" pillars and "reverse" pillars, respectively. The "coordinated" and "reverse" properties are represented by four arrows parallel to the outer edge of the rectangular pillar. For example... Figure 2 As shown, the four arrows on the "Shun" column exhibit a clockwise rotation relative to the center of the column; as... Figure 3As shown, the four arrows of the "reverse" column exhibit a counterclockwise rotation characteristic relative to the center of the column.

[0038] S1: Divide the layout area, such as Figure 4 As shown,

[0039] S11: Based on the distribution characteristics of the oil pool and the main transformer foundation, the oil pool is divided into the area directly opposite the short side of the main transformer foundation, the area directly opposite the long side of the main transformer foundation, the corner area of ​​the oil pool, and the middle area of ​​the main transformer foundation.

[0040] S12: For ease of description and recording, the area directly opposite the short side of the main transformer foundation is defined as Region 1, the area directly opposite the long side of the main transformer foundation is defined as Region 2, the corner area of ​​the oil tank is defined as Region 3, and the middle area of ​​the main transformer foundation is defined as Region 4. The oil tank is then laid out as follows: Figure 3 As shown, after the layout is completed, the first area 1 has two elements, the second area 2 has two elements, the third area 3 has four elements, and the fourth area 4 has four elements.

[0041] S2: As Figure 5 As shown, key support pillars are arranged:

[0042] S21: Arrange a row of key pillars in the first area 1. The key pillars arranged in this area are characterized by their center lines coinciding with the center lines of the short side of the foundation.

[0043] S22: Arrange a row of key pillars in the second area 2. The key pillars in this area are characterized by their upper or lower edges being flush with the extension line of the short side of the foundation.

[0044] S3: Adjust the support pillar: such as Figure 6 As shown, support columns are arranged in the third region 3 and the fourth region 4, so that the center line of the support column coincides with the center line of the key support column in the first region 1 and the second region 2. The number of rows and columns of support columns are adjusted according to the grid specifications.

[0045] S4: Assign the supports "forward" and "reverse" properties, and make the supports arranged at intervals. This includes the following steps:

[0046] S41: Assign "forward" or "reverse" properties to the key pillars in the second area 2. If the upper edge of the pillar is flush with the extension line of the short side of the foundation, then the pillar is assigned "reverse" property; otherwise, it is assigned "forward" property. Pillars that conform to "forward" property are defined as "forward" pillars, and pillars that conform to "reverse" property are defined as "reverse" pillars.

[0047] S42: Based on the "forward" and "reverse" orientation of the key supports in Zone 2, arrange "forward" and "reverse" supports. Following the principle of alternating "forward" and "reverse" support arrangements, deduce the "forward" and "reverse" orientation of all supports in Zone 1, Zone 3, and Zone 4, as follows: Figure 7As shown; the “forward” and “reverse” columns appear in pairs in the oil pool, and the total number of columns is an even number.

[0048] S5: Determine the area based on the "clockwise" and "counterclockwise" properties of the pillars, and complete the layout of the grille, such as... Figure 8 As shown;

[0049] S51: Extend the support edge line in the direction of the "clockwise" and "counterclockwise" arrows to the adjacent support, foundation and oil tank edge lines to form an extension line;

[0050] S52: The extension line divides the oil pool into several areas, each of which is a grid plate area. The grid layout can be completed according to the "forward and reverse" properties.

[0051] The applicable conditions for the method of the present invention are that all the supports in the oil tank are rectangular columns with the same cross-sectional size, the grid is placed on angle steel (steel plate), and the angle steel (steel plate) is fixed to the support, foundation and side wall of the oil tank.
