Description

Technical Field

[0001] This application relates to the field of busbar support positioning technology, and in particular to a generator stator busbar support positioning tool. Background Technology

[0002] With the rapid development of the pumped storage industry, new requirements have been placed on the installation efficiency and construction quality of pumped storage units. Currently, in the construction of pumped storage power stations in China, the generator stator is mostly a two-part structure. It is transported to the site for assembly, welding, lamination, and installation. During the stator installation process, the segmented busbars (copper rings) need to be assembled and welded on-site. Due to the large number of busbar segments, the positioning during on-site installation is difficult and the work is cumbersome. Furthermore, the installation of the busbars is carried out after the wire rods are embedded, making it difficult to position them based on the generator center.

[0003] To improve the positioning efficiency of stator busbar brackets, shorten the construction period, reduce the positioning error of each busbar bracket, and enable them to be reused repeatedly, a tool for rapid positioning of busbar brackets during on-site assembly of generator stators needs to be designed to improve the positioning efficiency of stator busbar brackets and thus ensure the quality of stator offline construction. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a generator stator busbar support positioning tool, which aims to solve the problem of difficult positioning when the busbar has many segments during on-site installation.

[0005] This application provides a generator stator busbar support positioning tool, including:

[0006] Positioning ruler, support block, and standard ruler;

[0007] The positioning ruler is installed vertically at the tail of the standard ruler, and the support block is installed vertically in the middle of the standard ruler;

[0008] The thickness of the positioning ruler, support block, and standard ruler shall not exceed the width of the ventilation slot between the two stator laminations. The length of the standard ruler shall be the horizontal length from the inner wall of the stator core to the center of the busbar support. The length of the support block shall not exceed the length from the upper tooth pressure plate to the inner wall of the stator core.

[0009] Optionally, in some embodiments, the generator stator busbar support positioning tool further includes:

[0010] Positioning bolts and telescopic ruler;

[0011] The telescopic ruler is installed inside the front end of the standard ruler, and the positioning bolt is installed on the standard ruler. The positioning bolt passes through the standard ruler and connects to the telescopic ruler. The position of the telescopic ruler inside the standard ruler is controlled by the positioning bolt.

[0012] The telescopic ruler has graduations, which allow you to quickly determine the extension length of the ruler.

[0013] Optionally, in some embodiments, the positioning ruler, support block, standard ruler, and telescopic ruler are made of acrylic sheet as a whole, and the positioning ruler, support block, standard ruler, and telescopic ruler need to be ground to remove the edges and burrs.

[0014] The technical solution provided in this application may include the following beneficial effects:

[0015] The positioning device consists of a positioning ruler, a support block, and a standard ruler. By fixing the horizontal length from the inner wall of the stator core to the center of the busbar bracket to the standard ruler and using the support block for fixation, the outer edge of the positioning ruler is made to fit tightly against the inner wall of the stator lamination. The tool is then installed in the required position and quickly marked, reducing the need for repeated measurement and positioning of each busbar bracket and greatly improving construction efficiency.

[0025] Currently, in the construction of pumped storage power stations in China, generator stators are mostly of a two-part structure. They are transported to the site for assembly, welding, lamination, and installation. During the stator installation process, the segmented busbars (copper rings) need to be assembled and welded on-site. Due to the large number of busbar segments, on-site positioning is difficult and cumbersome. Furthermore, the busbars are installed after the rods are inserted, making it difficult to position them based on the generator center. To improve the positioning efficiency of the stator busbar brackets, shorten the construction period, reduce the positioning error of each busbar bracket, and enable their reuse, a tool for rapid positioning of the busbar brackets during on-site generator stator assembly needs to be designed. This will improve the positioning efficiency of the stator busbar brackets and thus ensure the quality of the stator installation.

[0026] To address the aforementioned issues, this application provides a generator stator busbar support positioning tool. This tool comprises a positioning ruler, a support block, and a standard ruler. By fixing the horizontal length from the inner wall of the stator core to the center of the busbar support to the standard ruler and securing it with the support block, the outer edge of the positioning ruler is brought into close contact with the inner wall of the stator laminations. The tool is then installed in the desired position, quickly marking the location. This reduces the need for repeated measurement and positioning of each busbar support, significantly improving construction efficiency.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] Figure 1 This is a schematic diagram of the generator stator busbar support positioning tool shown in an embodiment of this application.

[0029] See Figure 1 A generator stator busbar support positioning tool, comprising:

[0030] Positioning ruler 1, support block 2, standard ruler 3, positioning bolt 4, telescopic ruler 5, stator laminations 6, and upper tooth pressure plate 7;

[0031] The positioning ruler 1, support block 2, standard ruler 3, and telescopic ruler 5 are made of acrylic sheet as a single piece. The positioning ruler 1 is vertically installed at the tail of the standard ruler 3, and the support block 2 is vertically installed in the middle of the standard ruler 3. The thickness of the positioning ruler 1, support block 2, and standard ruler 3 does not exceed the width of the ventilation groove between the two stator laminations; the greater the thickness, the more stable the system. The length of the standard ruler 3 is the horizontal length from the inner wall of the stator core to the center of the busbar support. The length of the support block 2 does not exceed the length from the upper tooth pressure plate 7 to the inner wall of the stator core. The positioning ruler 1, support block 2, standard ruler 3, and telescopic ruler 5 need to be ground to remove sharp edges and burrs to prevent them from falling into the stator core and being difficult to clean.

[0032] The telescopic ruler 5 is installed inside the front end of the standard ruler 3. The positioning bolt 4 is installed on the standard ruler 3, passing through the standard ruler 3 and connecting to the telescopic ruler 5. The position of the telescopic ruler 5 within the standard ruler 3 is controlled by the positioning bolt 4. The telescopic ruler 5 is equipped with graduations, allowing for quick determination of its extension length. The telescopic ruler 5 and the standard ruler 3 can be used for positioning and installation on generator stator busbar brackets of different sizes.

[0033] When using this application, it is necessary to verify that the lengths of the standard ruler 3 and the telescopic ruler 5 conform to the design values. Position the tool correctly on the upper part of the stator core, and slowly move it to insert the support block 2 into the ventilation slot between the two stator laminations. This completes the tool positioning. Move the tool within the slot until the outer edge of the tool positioning ruler 1 is flush with the inner wall of the stator lamination. At this point, observe the position of the end of the telescopic ruler 5 on the standard ruler and mark it with a marker or other marking material. This position is the center of the busbar support. Repeating this process once completes the easy and accurate positioning of the busbar support.

[0034] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
