[0029] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0030] The embodiment of the present application provides a prefabricated foundation for a transformer. The top of the prefabricated foundation has an installation plane, and the installation plane has an installation area 10 for installing the transformer. The prefabricated foundation includes a first component 20 and a second component 30 that are independent of each other.

[0031] The first component 20 includes a first base 21 and a first extension 22, both of which are rectangular blocks. The first extension 22 is located at an end of the first base 21. The first extension 22 and the first base 21 are integrally formed. One end of the first extension 22 is connected to one end of the first base 21. Both sides of the first base 21 and the first extension 22 have contact surfaces 40. The two sides with the contact surfaces 40 are the remaining two planes of the first base 21 or the first extension 22 except for the two ends, the top and the bottom. The contact surface 40 of the first base 21 and the contact surface 40 of the first extension 22 located on the same side form a semi-open first accommodating area 23.

[0032] The second member 30 includes a second base 31 and a second extension 32. The second base 31 and the second extension 32 are integrally formed. One end of the second extension 32 is connected to one end of the second base 31. The second base 31 and the second extension 32 both have a contact surface 40 on the same side. Sides of the second base 31 and the second extension 32 away from the contact surface 40 are in the same plane. The contact surface 40 of the second base 31 and the contact surface 40 of the second extension 32 form a semi-open second accommodating area 33.

[0033] There are two second components 30. In the installed state, the second base 31 of the second component 30 enters the first accommodating area 23, and the first base 21 of the first component 20 enters the second accommodating area 33. The end faces of the first base 21 and the second base 31 are in contact. When the bisecting plane between the two contact surfaces 40 of the first base 21 is taken as the symmetry plane, the prefabricated foundation is symmetrical about the symmetry plane.

[0034] The following is a further introduction based on specific usage scenarios.

[0035] During use, the operator digs a pit at the designated installation location, then adjusts the position of a first component 20 and two second components 30 that have been formed and places them into the pit, and splices them into an installation foundation for installing the transformer. After the prefabricated foundation serving as the installation foundation is assembled, the two contact surfaces 40 on the same side of the first base 21 and the first extension 22 are tightly attached to the contact surfaces 40 of the second extension 32 and the second base 31 on the second component 30, respectively. The two sides of the first base 21 are respectively embedded in the second accommodating areas 33 of the two second components 30, and the second bases 31 of the two second components 30 are respectively embedded in the first accommodating areas 23 on both sides of the first extension 22, forming a complete prefabricated foundation. The operator can then install the frame at the bottom of the transformer on the installation plane at the top of the prefabricated foundation. The connection point between the frame at the bottom of the transformer and the top of the prefabricated foundation is located in the installation area 10. Generally speaking, for small transformers, the frame at the bottom can be a steel frame or a concrete pier. For large transformers, the frame at the bottom is a concrete pier, where the concrete pier can also be a prefabricated component.

[0036] It can be found that the prefabricated foundation is used as the installation foundation of the transformer in the embodiment of the present application, and there is no need for operators to perform on-site pouring construction, which significantly improves the overall installation efficiency of the transformer. In addition, the prefabricated foundation in the embodiment of the present application is set up in a split manner, which is convenient for transportation and on-site installation and adjustment.

[0037] In the embodiment of the present application, the first component 20 and the two second components 30 together constitute a prefabricated foundation serving as an installation basis. When one of the components in the prefabricated foundation is subjected to a horizontal force, the end faces of the first base 21 and the second base 31, the contact surface 40 of the first base 21 and the second base 31, and the contact surface 40 of the first extension member 22 and the second extension member 32 can all provide positive pressure to prevent the movement tendency of the component.

[0038] In a feasible implementation method of the embodiment of the present application, the first base 21, the first extension member 22, the second base 31 and the second extension member 32 are in the shape of rectangular blocks, the contact surfaces 40 on the first base 21 and the first extension member 22 are parallel to each other, the contact surface 40 on the first base 21 is perpendicular to the end face of the first base 21, the contact surface 40 of the second base 31 and the second extension member 32 on the second member 30 are parallel, and the contact surface 40 on the second base 31 is perpendicular to the end face of the second base 31. By setting the first base 21, the first extension member 22, the second base 31 and the second extension member 32 in a rectangular block shape, when the first member 20 and the two second members 30 are assembled, the operator can more easily assemble the first member 20 and the two second members 30 into a prefabricated foundation, further improving the efficiency of on-site installation.

[0039] The first base 21 and the second base 31 are both provided with mounting holes 50 for mounting the transformer. There are a plurality of mounting holes 50 provided on the first base 21 and the second base 31. The plurality of mounting holes 50 are linearly arranged at equal intervals. The mounting holes 50 are located in the mounting area 10. In the prior art, a fixed frame is generally fixed to the bottom of the transformer. The operator can use bolts to install the fixed frame on the top of the prefabricated foundation. The linear arrangement of the plurality of mounting holes at equal intervals also facilitates the operator to install according to the actual gauge of the transformer, and has high applicability.

[0040] In a feasible implementation method of the embodiment of the present application, there are two installation areas 10, the first installation area 10 is located in the top plane of the first base 21, the installation hole 50 on the first base 21 is located in the first installation area 10, the middle part of the first extension member 22 and the middle parts of the two second bases 31 are both located in the second installation area 10, and the installation holes 50 on the two second bases 31 are located in the second installation area 10. During installation, one side of the fixed frame at the bottom of the transformer is installed in the first installation area 10 and fixedly connected to the first base 21, and the other side of the fixed frame is installed in the second installation area 10. The fixed frame located in the second installation area 10 spans the first extension member 22 and the second bases 31 of the two second components 30, that is, the second bases 31 of the two second components 30 are both fixedly connected to the fixed frame. In this way, under the fixation of the fixed frame at the bottom of the transformer, several components in the prefabricated components are connected as a whole by the transformer fixed frame, thereby improving the stability of the prefabricated foundation and the overall transformer installation.

[0041] In a feasible implementation method of the embodiment of the present application, it also includes several filling pieces 60. In the installed state, the several filling pieces 60 are respectively located in the second accommodating area 33 and the first accommodating area 23. When the gauge of the transformer is large and the size of the prefabricated foundation needs to be adjusted, the operator can use the filling pieces 60 to be placed in the first accommodating area 23 and the second accommodating area 33, and adjust the distance between the first component 20 and the second component 30 to increase the size of the prefabricated foundation. The operation process is simple.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
