[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Please refer to Figures 1-4 , the present application will be described in detail by the following embodiments:

[0029] A box transformer foundation platform considering an oil collection pool, used for installing a box transformer body 6, such as the installation schematic diagram shown in Figure 1 and Figure 2 , comprises:

[0030] The base platform 2 is horizontally installed on the support column leg 5, which is obviously different from the existing buried structure, and the support column leg 5 provides a lower hollow structure, which is convenient for subsequent cable laying and the like, and occupies less land than the buried structure, which is beneficial to land saving; such as the positional relationship shown in Figure 3 and Figure 4 , the base platform 2 is provided with a first turned along 21 at the board along, and a second turned along 23 is provided around the four sides of the box transformer body 6, and the first turned along 21 and the second turned along 23 are provided with an oil collection pool body 201 corresponding to the oil tank leakage area of the box transformer body 6, which is mainly used for containing leaked insulating oil, in order to avoid liquid splashing into the second turned along 23, the oil hole 231 for flowing insulating oil or accumulated water to the oil collection pool body 201 is arranged on the second turned along 23, and in order to more uniformly contain insulating oil, the flow guide hole for flowing insulating oil or accumulated water is arranged between adjacent oil collection pool bodies 201, thereby forming a conduction path, avoiding overflow of a single oil collection pool body 201, such as the relationship shown in Figure 3 , the oil collection pool body 201 in the present embodiment is embedded, so that the steel grid 3 is horizontally consistent with the base platform 2.

[0031] Specifically, the steel grid 3 in the present embodiment is respectively shown in Figure 3 and Figure 4The structure is installed on the oil collecting pool body 201, and the steel grating 3 is paved with pebbles as a stone layer, and the embodiment is provided with a vertical sealing edge 22 at the pool edge of the oil collecting pool body 201, which is connected between the first turning edge 21 and the second turning edge 23, so that the pebble layer can be laid in a better limited manner.

[0032] It should be explained that the steel grating 3 is provided with grating holes 31, and the particle size of the grating holes 31 is smaller than that of the pebbles; when there is a problem such as aging and leakage of the parts in the tank body 6, the insulating oil liquid can flow into the oil collecting pool body 201 through the pebbles, so as to reduce the outflow accident of the oil liquid; and the pebble layer can prevent the oil liquid from splashing, can play a isolation role, prevent the fire source and the fire from spreading to the ground, and is beneficial to fire extinguishing; and the pebble layer plays a cooling role, can conduct heat to cool the oil liquid, the pebble is insulated, and it is convenient for maintenance and operation personnel to check the work, and the setting of the pebble can prevent the growth of weeds in the oil collecting pool body 201.

[0033] The embodiment is provided with a drainage pipe 4 on the oil collecting pool body 201 in a conductive manner, and the drainage pipe 4 is provided with a manual valve, which can be used for discharging the insulating oil or accumulated water in the oil collecting pool body 201.

[0034] It should be noted that the fire wall 1, the foundation platform 2 and the step ladder 7 of the application can be prefabricated components or cast-in-place concrete after the frame is built on site, which has the characteristics of simple and efficient construction, and the structure of the application is more convenient than the traditional buried type for cleaning oil liquid and accumulated water, has less maintenance work in the later period, and has strong practicality.

[0035] It should be explained that if the embodiment of the application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition and the like between the components in a certain specific posture, and if the specific posture changes, the directional indications also change accordingly.

[0036] In addition, if the embodiment of the application involves the description of "first", "second" and the like, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.
