Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a novel prefabricated transformer substation. Background Art

[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid.

[0003] As a hub for power transmission, common substations are mostly customized according to the use environment to ensure long-term use. In the use of electricity on construction sites, due to the variability of the construction site, most of the time, a mounting base or four supporting piles will be cast at a suitable location. The prefabricated substation box is fixed on the base or supporting piles, and the internal components are installed and connected. However, some problems are currently encountered during the installation. For example, during the casting of the mounting base or supporting piles, the fixed holes are cast on the base, and the mounting holes of the prefabricated substation box are mostly fixed. If the holes on the base cannot be matched, new holes need to be drilled, and the operation is cumbersome. The mounting holes of the prefabricated box limit the scope of application to a certain extent. At the same time, the gaps between the electrical installation plates in the prefabricated box are mostly fixed, while the models of external equipment vary. This may lead to the problem of too small gaps between the mounting plates, reducing its scope of application.

[0004] Therefore, it is necessary to provide a new type of prefabricated substation to solve the above technical problems. Utility Model Content

[0026] Four screw rods 12 are fixedly installed in the prefabricated box 2, and the four screw rods 12 are fixedly installed on the top inner wall and the bottom inner wall of the prefabricated box 2. The four screw rods 12 are divided into rectangular arrays, and two lifting frames 13 are slidably installed on the four screw rods 12.

The lifting frames 13 are also U-shaped, and the opening sides of the lifting frames 13 and the supporting frames 14 are both facing the opening of the prefabricated box 2.

[0027] Four through-tubes 15 are fixedly installed on the two lifting frames 13, and the through-tubes 15 vertically penetrate the lifting frames 13 and are fixedly connected thereto.

[0029] The working principle of the new prefabricated substation provided by the utility model is as follows:

[0030] When it is necessary to install a prefabricated substation at a construction site or other place, the staff can first hoist the prefabricated box 2 to the top of the base or support pile. During the calibration process, the staff can rotate the four wheels 1 and 2 respectively. When the wheel 1 is rotated by an external force, it will drive the adjusting rod 7 to rotate. When the adjusting rod 7 is screwed with the threaded cylinder 6, the adjusting rod 7 will gradually move into the fixed frame 4 or move out of the fixed frame 4 (the adjusting rod 7 and the sliding frame 5 are connected through the bearing 1 702 so that the two will not affect each other), thereby pushing the sliding frame 5 to move along the direction of the limit rod, so that the adjustment can be made. The section positioning plate 11 and the horizontal direction of the fixed anchor hole, and the rotation of the turntable 2 by the external force will drive the transmission rod 8 to rotate. At this time, the sliding seat 9 is limited by the slider and the slide groove and cannot rotate with the transmission rod 8, and can only slide along the direction of the slide groove under the side effect of the thread. In this way, the vertical direction of the sliding seat 9 and the positioning plate 11 can be adjusted, and no matter how the sliding seat 9 moves, the top support plate 10 will contact the bottom of the mounting plate 1. After the prefabricated box body 2 is laid flat, the weight of the prefabricated box body 2 mainly acts on the positioning plate 11 through the top support plate 10, thereby not affecting the adjusting rod 7 and the transmission rod 8.

[0031] In the process of hanging the prefabricated box 2 in the above manner, the staff can adjust the positions of the four positioning plates 11 and the fixing anchor holes so that they can correspond to the installation holes of the base, thereby facilitating subsequent fixing operations.

[0032] At the same time, after opening the two door panels 3, the staff can install the electrical equipment on the two bearing frames 14. When the gap between the two bearing frames 14 is too large or too small, the staff can hold any one of the outer driving cylinders 17 and rotate it. After the driving cylinder 17 is rotated by external force, the corresponding synchronous pulley 18 will be driven to rotate, and under the transmission of the corresponding transmission belt 120, the inner synchronous pulley 2 19 and the driving cylinder 17 will be driven to rotate. At the same time, under the transmission effect of the transmission belt 21, the inner synchronous pulley 2 19 and the driving cylinder 17 on the other side will be driven to rotate. Further, under the transmission of the transmission belt 20 on the other side, the four driving cylinders 17 will eventually rotate in the same direction at the same time, and when the driving cylinder 17 and the screw rod 12 are screwed together, the four connecting cylinders 16, the lifting frame 13 and the lifting frame 13 will eventually be driven to move upward or downward, so as to adjust the spacing between the two bearing frames 14.

[0033] Compared with the related art, the new prefabricated substation provided by the utility model has the following beneficial effects:

[0034] The utility model provides a novel prefabricated substation. During the installation of the prefabricated substation, the positioning plate 11 can be adjusted in the horizontal and vertical directions by rotating the first and second wheels, thereby changing the position of the fixed anchor hole. During the installation, the alignment with the base mounting hole can be quickly achieved, which facilitates the installation and improves the scope of use to a certain extent. At the same time, the spacing between the two supporting frames 14 can be adjusted, further improving the adaptability of the device.
