Description

Technical Field

[0001] The present invention relates to the field of circuit breaker installation, in particular to an installation base and a power plant circuit breaker installation device. Background Art

[0002] The power plant's 220kV booster station originally had a 20-year-old hydraulically controlled circuit breaker. This type of equipment had a high failure rate, heavy maintenance workload, and low reliability. It was necessary to replace the circuit breaker to ensure the normal operation of the booster station.

[0003] Since the substation circuit breaker is relatively large, the installation foundation of the original circuit breaker is generally three foundation piles cast in the ground in an equilateral triangle. This type of installation foundation is not suitable for the new circuit breaker to be replaced. It takes more than 20 days to dismantle the old installation foundation and then rebuild a new one. Since it is a network-related equipment, it is difficult to shut down the equipment and the transformation is difficult, so it cannot meet the transformation period approved by the grid dispatcher. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is: how to provide a circuit breaker installation foundation to shorten the renovation period.

[0005] The above technical problems are solved by the following technical solutions: The present invention proposes an installation base, including a support part, which includes a plurality of independent support bodies, and a connecting piece can be formed on the support body by casting; a transition part, which spans between the plurality of support bodies, and the transition part is connected to the support body through a connecting piece, and the transition part has an installation surface, which is a horizontal surface.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0027] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0028] Reference Figure 1-4 , this embodiment provides an installation basis, including,

[0029] The support portion 1 includes a plurality of independent support bodies 11, on which connectors 12 can be formed by casting;

[0030] The adapter part 2 is arranged across multiple support bodies 11, and the adapter part 2 is connected to the support body 11 through a connecting member 12. The adapter part 2 has a mounting surface 21, and the mounting surface 21 is a horizontal surface; specifically, the adapter part 2 is horizontally arranged across multiple support surfaces 13, and the mounting surface 21 is a horizontal surface arranged at the upper end of the adapter part 2.

[0031] The support body 11 is specifically the old mounting base left after the original circuit breaker is removed. By installing the adapter 2 on the old mounting base to form a new mounting base suitable for the installation of the new circuit breaker, this renovation concept can shorten the renovation period, which originally required more than 20 days, to about 5 days, compared to the renovation method of removing the old mounting base and then remaking a new one. However, the design of the adapter 2 and the secure connection between the adapter 2 and the original mounting base (i.e., the support body 11) are design challenges.

[0032] The present application designs the adapter portion 2 to span between the supports 11. The supports 11 jointly support the adapter portion 2, thereby providing a stable support base at the bottom of the adapter portion 2. That is, the mounting surface 21 at the top of the adapter portion 2 is equivalent to being supported by the supports 11, thereby ensuring that the new circuit breaker has a stable bottom support after installation. At the same time, because the adapter portion 2 spans between multiple supports 11, the adapter portion 2 has a larger support bottom surface, thereby allowing a larger mounting surface 21 to be designed on the adapter portion 2 to meet the installation requirements of the new circuit breaker. If the bottom of the adapter portion 2 is smaller and the upper mounting surface 21 is larger, a support structure with a larger top and a smaller bottom will be formed, which is not conducive to support stability.

[0033] For the connection between the adapter 2 and the support body 11, if it is only fixed by bolt connection, the connection firmness is relatively low. Compared with the larger support pressure during actual use, the connection firmness is slightly insufficient, and there is a risk of the bolts detaching from the support body 11. By modifying the original old support body 11, a hole is dug on the old support body 11 and cast into a connecting piece 12 for installing the connecting adapter 2. The connecting piece 12 is not easy to detach from the support body 11 and has a high connection firmness, which solves the installation problem of the adapter 2.

[0034] When the circuit breaker of the power plant's booster station is replaced and modified, the original installation foundation of the circuit breaker is retained. By installing the adapter 2 on the original old installation foundation, the original old installation foundation is transformed into a new installation foundation suitable for the installation of the new circuit breaker. This can shorten the construction period of the circuit breaker replacement and modification, and meet the requirements of the network-related equipment for the modification period. At the same time, a connecting piece 12 is formed by pouring on the original installation foundation (i.e., the support body 11) for connecting the support body 11 and the adapter 2. The connecting piece 12 is not easy to separate from the support body 11, and the connection strength is high, which meets the support requirements of large circuit breakers.

[0035] In some embodiments, reference Figure 1-3 The support body 11 is a reinforced concrete pier. The support body 11 is at least partially buried in the ground. The part of the support body 11 exposed to the ground has a support surface 13. Specifically, the upper surface of the support body 11 is the support surface 13. The support surface 13 is a horizontal surface, and the support surfaces 13 on multiple support bodies 11 are at the same height. There is a casting hole 14 on the support surface 13, and the connecting piece 12 is formed by casting in the casting hole 14.

[0036] The support body 11 is specifically a concrete pier cast on the ground through a formwork. It is generally cylindrical, but of course it can also be other shapes, such as a rectangular parallelepiped. Most of the support body 11 is buried in the ground by casting to ensure the support strength. The upper part of the support body 11 is exposed to the ground, and the upper end of the support body 11 is the support surface 13. A casting hole 14 is dug on the support surface 13 by a drilling rig. The casting hole 14 can specifically be a rectangular hole or a circular hole. Of course, in order to improve the connection strength between the connector 12 and the support body 11 and reduce the risk of the connector 12 detaching from the support body 11, the casting hole 14 can also be designed as a structure with a small opening and a large interior. After the connector 12 is cast, the opening of the casting hole 14 also has a certain limiting effect on the connector 12, reducing the risk of the connector 12 detaching from the support body 11.

[0037] In some embodiments, reference Figure 3 The connecting member 12 includes a connecting body 121 cast in the casting hole 14, the upper surface of the connecting body 121 is flush with the supporting surface 13, and an embedded bolt 122 is provided in the connecting body 121, and the upper end of the embedded bolt 122 extends out of the connecting body 121.

[0038] The connecting member 12 specifically includes a connecting body 121 cast on the support body 11 and an embedded bolt 122 embedded in the connecting body 121. The connecting member 12 and the support body 11 are firmly connected through the connecting body 121. The embedded bolt 122 is pre-placed into the casting hole 14 during casting. After casting, the embedded bolt 122 is firmly anchored in the connecting body 121. The part of the embedded bolt 122 extending out of the connecting body 121 and the adapter 2 are fixed together by a nut.

[0039] In one embodiment provided in this application, referring to Figure 1 and Figure 4 The adapter 2 includes a frame plate 22 spanning multiple support bodies 11. The frame plate 22 is detachably connected to the connector 121 through embedded bolts 122. A U-shaped channel steel 23 is provided on the frame plate 22. A mounting plate 24 is provided on the upper part of the U-shaped channel steel 23. The upper surface of the mounting plate 24 is a horizontally arranged mounting surface 21.

[0040] The part of the embedded bolt 122 extending out of the connecting body 121 passes through the frame plate 22 and is fixed together with the frame plate 22 by a nut. The upper part of the frame plate 22 is fixed to the U-shaped channel steel 23 by welding, and the upper part of the U-shaped channel steel 23 is fixed to the mounting plate 24 by welding. The U-shaped channel steel 23 serves as a transition connection between the frame plate 22 and the mounting plate 24.

[0041] In one embodiment provided in this application, referring to Figure 1 and Figure 4 There are three support parts 1, and the three support parts 1 are arranged in an equilateral triangle. The frame plate 22 corresponds to the equilateral triangle frame plate 22, and a U-shaped channel steel 23 is provided on the upper part of each side of the frame plate 22.

[0042] The old installation foundation of the power plant booster station generally adopts three cast piers, which are arranged in an equilateral triangle. The frame plate 22 adopts a triangular plate accordingly, so that the frame plate 22 matches the layout position of the support part 1, so that the frame plate 22 is evenly supported by multiple support bodies 11. Of course, some old installation foundations of the power plant booster station also adopt other numbers of support bodies 11, such as four support bodies 11 arranged in four corners. At this time, the frame plate 22 is correspondingly designed as a square frame plate 22.

[0043] In one embodiment provided in the present application, the connector 121 is a reinforced concrete casting, and the frame plate 22, the U-shaped channel steel 23 and the mounting plate 24 are all hot-dip galvanized steel plates.

[0044] Reference Figure 5 A power plant circuit breaker installation device includes an upper installation base and further includes:

[0045] The mounting portion 3 is vertically arranged on the mounting surface 21 .

[0046] The mounting portion 3 is used for mounting a new type of circuit breaker.

[0047] In some embodiments, reference Figure 5 The mounting portion 3 includes a vertically arranged mounting column 31 , a connecting plate 32 is fixed to the lower end of the mounting column 31 , and the connecting plate 32 is detachably mounted on the mounting surface 21 by bolts.

[0048] Since the adapter part 2 has a sufficiently large mounting surface 21, the lower end of the mounting part 3 can be directly fixed on the mounting surface 21. Specifically, the mounting part 3 includes a mounting column 31 for mounting the new circuit breaker. The lower end of the mounting column 31 is welded with a connecting plate 32. The connecting plate 32 has a larger contact area than the mounting column 31. The mounting column 31 is mounted on the mounting surface 21 through the connecting plate 32, which has better firmness. The connecting plate 32 is specifically detachably connected to the mounting surface 21 by bolts.

[0049] In some embodiments, reference Figure 6-9The power plant circuit breaker installation device also includes an auxiliary fixing portion 4 arranged between multiple support bodies 11. The auxiliary fixing portion 4 includes a support column 41 that is at least partially anchored into the ground. The upper end of the support column 41 extends out of the ground. The upper end of the support column 41 is provided with a receiving groove 42. The lower end of the installation column 31 extends downward with an extension portion 43. The extension portion 43 passes through the installation surface 21 and is arranged in the receiving groove 42. The extension portion 43 and the support column 41 are fixed by a positioning pin 44.

[0050] In order to further improve the stability of the installation of the mounting column 31, an auxiliary support part 1 is provided at the lower end of the mounting column 31. The auxiliary support part 1 is supported between the ground and the mounting column 31. Of course, there are through holes for the extension part 43 to pass through on the connecting plate 32 and the mounting surface 21. The auxiliary support part 1 improves the stability of the installation of the mounting column 31 while having a certain supporting effect on keeping the mounting column 31 in a vertical state, thereby reducing the possibility of the mounting column 31 tilting.

[0051] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
