Description

Technical Field

[0001] The invention relates to the technical field of busbar arrangement, in particular to a 35KV busbar arrangement structure installed at a short distance. Background Art

[0002] The 35KV busbar is a high-voltage cable used for electric energy transmission, which can be rated at 35 kilovolts. The busbar is an important component in the power system, used to transmit electric energy from the power station to each user terminal. Compared with the traditional iron tower transmission line, the busbar used in the pipe and switch station does not need to be suspended in the air, but is laid on the surface of the station, and can be installed and arranged according to the actual wiring and easy maintenance needs.

[0003] The invention with publication number CN107039891B discloses a 35kV busbar arrangement structure, which adopts the method of hanging the C-phase conductor and the 0-phase conductor on the steel column, saving the width of the steel frame beam; reducing the layout size of the 35kV busbar and saving the floor space;

[0004] The invention of publication number CN115051244A discloses a main busbar device and its installation method, which has a higher current carrying capacity and can effectively reduce the operating temperature of the equipment. The cross-sectional area is smaller under the same rated current and temperature rise requirements, which can reduce the amount of copper material used. At the same time, the main busbar device of the present invention proposes to use the gap between busbars to pass the connecting bolts, and there is no need to drill holes on the main busbar during the design and production process, thus realizing standardized design and production;

[0005] However, the above-mentioned arrangement mechanism for busbar installation still has the following problems during actual use: although the busbar is positioned, installed and arranged by means of the set steel frame beam, the installation height and range of such steel frame beams cannot be subsequently adjusted according to the wiring requirements in the site, and the expansion and contraction compensation under different climates cannot be conveniently adjusted. At the same time, when additional busbars are subsequently installed, the arrangement mechanism cannot be added, and the arrangement mechanism needs to be re-customized, which limits the convenient adjustment of the busbar arrangement.

[0006] Therefore, we propose a short-distance installed 35KV busbar layout structure to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a 35KV busbar layout structure for short-distance installation, in order to solve the existing problem of positioning, installing and arranging the busbar by setting up steel frame beams, but the installation height and range of such steel frame beams cannot be subsequently adjusted according to the wiring requirements in the site, and the expansion and contraction compensation under different climates cannot be conveniently adjusted.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0041] like Figure 1 , Figure 9-10As shown, the mounting base 1 is arranged at the required length in the station, and then when the distance between the telescopic brackets 3 on the left and right sides needs to be adjusted, the bidirectional pitch-adjusting screw 6 arranged on the bottom surface of the mounting base 1 is rotated to drive the telescopic brackets 3 threadedly connected on the left and right sides to move to change the spacing. At the same time, when the telescopic bracket 3 moves, its stability is ensured by the guide brackets 2 arranged on the front and rear sides above the mounting base 1. The telescopic bracket 3 with adjustable spacing is convenient for the subsequent bearing and lifting of the busbar during installation, thereby ensuring the stability of the busbar during installation.

[0042] Furthermore, by manually rotating the lifting sleeve 7 arranged on the outside of the telescopic bracket 3, the lifting threaded rod 8 threadedly connected to the lifting sleeve 7 is fixedly installed on the outside of the main arrangement frame 4, so that the rotating lifting sleeve 7 drives the lifting threaded rod 8 and the main arrangement frame 4 to be lifted and lowered, thereby meeting the height adjustment requirement during arrangement and installation. At the same time, the bottom end of the main arrangement frame 4 is fixedly connected to the top end of the telescopic bracket 3, so that the telescopic bracket 3 can provide limiting support during the height adjustment process.

[0043] Embodiment 2: In order to solve the problems existing in the layout of the existing short-distance installed 35KV busbar, this embodiment adopts the following technical scheme, wherein a layout mechanism is arranged on both sides of the upper left and right sides of the mounting base 1, and the layout mechanism includes a main layout frame 4 and a sub-layout frame 5, and the sub-layout frame 5 is slidably arranged inside the main layout frame 4 in a front-to-back symmetrical manner; the middle part of the outer side of the main layout frame 4 included in the layout mechanism is fixedly connected to the top of the lifting threaded rod 8, and a driving gear 9 is rotatably arranged at the center position of the bottom surface of the main layout frame 4 through a bearing, and driven racks 10 are slidably arranged on both sides of the bottom surface of the main layout frame 4, and the driving gear 9 is meshed with the driven racks 10 on the left and right sides.

[0044] The outer end of the driven rack 10 included in the arrangement mechanism is fixedly connected to the outer end of the bottom surface of the front and rear side auxiliary arrangement frames 5, and the front and rear side auxiliary arrangement frames 5 are driven by the driven rack 10 to move forward and backward inside the main arrangement frame 4, and the main arrangement frame 4 is height-adjusted by the lifting sleeve 7 and the lifting threaded rod 8 included in the distance adjustment mechanism, so as to adjust the installation height required for different busbars; the arrangement mechanism includes a bidirectional positioning screw 11, and the bidirectional positioning screw 11 is rotatably arranged inside the auxiliary arrangement frame 5 through a bearing, and the front and rear side outer walls of the bidirectional positioning screw 11 inside the auxiliary arrangement frame 5 are threadedly connected with a positioning slider 12, and the top horizontal height of the symmetrically arranged positioning sliders 12 is lower than the top horizontal height of the auxiliary arrangement frame 5.

[0045] like Figure 4-Figure 7As shown, the auxiliary arrangement frame 5 in the initial state is accommodated inside the main arrangement frame 4. When the auxiliary arrangement frame 5 needs to be extended for use, the driving gear 9 arranged on the bottom surface of the main arrangement frame 4 is manually rotated to drive the driven racks 10 meshingly connected on the left and right sides to move forward and backward, and the driven racks 10 drive the auxiliary arrangement frame 5 fixedly connected at the outer end to move outward, thereby changing the range of the extended auxiliary arrangement frame 5 extending beyond the main arrangement frame 4, so that it can be installed through the auxiliary arrangement frame 5 when the busbar arrangement needs to be supplemented.

[0046] When the busbar is installed on the auxiliary layout frame 5, the bidirectional positioning screw 11 installed inside the auxiliary layout frame 5 is rotated to drive the positioning sliders 12 threadedly connected on the front and rear sides to move forward and backward, so as to change the distance between the front and rear positioning sliders 12, and then adjust the spacing of the busbar installation according to different requirements to adapt to the installation of the layout base 13.

[0047] Embodiment 3: In order to solve the problems existing in the arrangement of the existing short-distance installed 35KV busbar, this embodiment adopts the following technical scheme, the arrangement mechanism includes a main arrangement frame 4 and a sub-arrangement frame 5, both of which are provided with an arrangement base 13 at the top, and the arrangement base 13 on the top surface of the main arrangement frame 4 is fixedly installed in an equidistant manner, and the arrangement base 13 on the top surface of the sub-arrangement frame 5 is fixedly installed on the top of the positioning slider 12 by bolts; positioning arc plates 14 are slidably provided on the front and rear sides of the interior of the arrangement base 13, and driving tooth blocks 15 are fixedly provided on the outer walls below the front and rear positioning arc plates 14 at equidistant intervals, and driving gears 16 are rotatably provided on the front and rear sides of the interior of the arrangement base 13 through torsion springs, and the driving gears 16 on the front and rear sides are meshedly connected to the driving tooth blocks 15 on the outer walls below the positioning arc plates 14.

[0049] like Figure 7-Figure 8As shown, when the busbar is arranged and installed, the arrangement base 13 is installed above the main arrangement frame 4, and the positioning slider 12 inside the auxiliary arrangement frame 5 installs the arrangement base 13. At the same time, the busbar is placed above the arrangement base 13, and the resistance lifting plate 17 above the arrangement base 13 is pressed downward to move downward. At the same time, the descending resistance lifting plate 17 loosens the traction steel cable 18 fixedly connected at the outer end, and then loosens the winding drive gear 16, so that the drive gear 16 connected to the torsion spring rotates, driving the meshing drive gear block 15 and the positioning arc plate 14 to move upward, so as to position and lock the installed busbar, so as to improve the stability of the busbar arrangement.
