Description

A prefabricated box-type substation with rapid heat dissipation Technical Field

[0001] This utility model specifically relates to the field of prefabricated box-type substation technology, and more specifically to a fast-heat dissipation prefabricated box-type substation. Background Technology

[0002] A prefabricated substation is a compact set of equipment that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, power metering equipment, and reactive power compensation devices in one or more enclosures according to a certain wiring scheme. It generally consists of a high-voltage compartment, a transformer compartment, and a low-voltage compartment. The transformer generates a lot of heat during operation and is the key part of heat dissipation in the prefabricated substation. Generally, ventilation openings and exhaust fans are installed in the transformer compartment. Some prefabricated substations also use heat sinks and other devices to increase the heat dissipation area of ​​the transformer and improve the heat dissipation effect.

[0003] However, in practice, it has been noted that most heat dissipation effects are currently determined by the airflow of the cooling fan. When airflow passes through the transformer, it changes direction due to the obstruction of the internal structure. Only part of the airflow will pass over the surface of the transformer, and the airflow on the transformer surface varies greatly, affecting the heat dissipation effect on the transformer. Furthermore, the heating conditions of different parts of the transformer are different, and the acceleration of the airflow as a whole cannot solve the problem of severe local heating. Therefore, it is impossible to quickly dissipate heat from the severely heated parts. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated box-type substation with rapid heat dissipation. Through the coordinated operation of four electric cylinders, the cooling fan's exhaust direction is directed at the desired angle, allowing for direct airflow to areas of the transformer with high heat output and precise heat dissipation of severely overheated parts, thereby improving the transformer's heat dissipation effect. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated box-type substation with rapid heat dissipation includes a steel structure frame, with a high-voltage electrical compartment isolation plate and a low-voltage electrical compartment isolation plate fixedly connected to both ends of the steel structure frame, and symmetrical transformer compartment doors are provided between the high-voltage electrical compartment isolation plate and the low-voltage electrical compartment isolation plate;

[0007] Each of the aforementioned transformer room doors is symmetrically embedded with an air intake filter, and each of the aforementioned air intake filters is movably connected to a fast radiator on the side near the steel structure frame via an airflow angle adjustment frame arranged in a rectangular array.

[0008] The airflow angle adjustment frame has an electric cylinder that is movably connected to the transformer chamber door and the fast radiator at both ends. The electric cylinder is fixedly connected to a fixed ball head and a connecting ball head at both ends, and a spherical bushing is also engaged on the outside of the connecting ball head.

[0009] As a further technical solution of this utility model, the electric cylinder is provided with a ball head holder at one end near the fixed ball head, and the fixed ball head and the ball head holder are engaged and cooperated, while the other side of the ball head holder is fixedly connected to the transformer room door.

[0010] As a further technical solution of this utility model, the rapid heat sink includes a hollow frame, on which spherical slots corresponding to spherical bushings are provided in a rectangular array, and the spherical bushings are engaged with the inner side of the spherical slots.

[0011] As a further technical solution of this utility model, a cooling fan is fixedly connected in the hollow frame, and a connecting hose is fixedly connected to the end of the cooling fan away from the hollow frame, and the other end of the connecting hose is fixedly connected to the air intake filter.

[0012] As a further technical solution of this utility model, the high-voltage electrical room isolation plate and the low-voltage electrical room isolation plate divide the inner side of the steel structure frame into three parts, which are, from left to right, the low-voltage power distribution room, the transformer installation room and the high-voltage power distribution room.

[0013] As a further technical solution of this utility model, a rain shelter roof is fixedly connected above the steel structure frame, and the rain shelter roof covers the low-voltage power distribution room, the transformer installation room and the high-voltage power distribution room respectively. The side of the high-voltage power distribution room isolation plate and the side of the low-voltage power distribution room isolation plate are respectively provided with wire-passing grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model uses electric cylinders arranged in a rectangular array to adjust the orientation and posture of the hollow frame. The output rod of each electric cylinder is in a different position, and the cooling fan in the hollow frame is also in a different direction. By changing the direction of the cooling fan, the airflow can be blown directly to the local heat-generating area after entering, thereby quickly cooling the area with severe local heat.

[0016] In this invention, one end of the electric cylinder is movably connected to the ball head holder via a fixed ball head, and the other end is movably connected to the ball groove via a connection ball head and a ball bushing. This allows for more flexible adjustment of both ends of the electric cylinder, increases the adjustment angle of the cooling fan, and enables precise heat dissipation for areas with severe localized heat generation.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7. This utility model embodiment provides a fast heat dissipation prefabricated box-type substation, including a steel structure frame 8. High voltage electrical room isolation plate 1 and low voltage electrical room isolation plate 3 are fixedly connected to both ends of the steel structure frame 8, and symmetrical transformer room doors 2 are provided between the high voltage electrical room isolation plate 1 and the low voltage electrical room isolation plate 3.

[0028] Each of the transformer room doors 2 is symmetrically embedded with an air intake filter 4, and each of the air intake filters 4 is movably connected to a fast radiator 6 on the side near the steel structure frame 8 via an airflow angle adjustment frame 7 arranged in a rectangular array.

[0029] Among them, the airflow angle adjustment frame 7 has an electric cylinder 71 that is movably connected to the transformer chamber door 2 and the fast radiator 6 at both ends, and a fixed ball head 73 and a connecting ball head 74 are fixedly connected to both ends of the electric cylinder 71, and a spherical bushing 75 is also engaged on the outer side of the connecting ball head 74.

[0030] By adopting the above technical solution, one end of the electric cylinder 71 is movably connected to the ball head holder 72 through the fixed ball head 73, and the other end is movably connected to the rapid radiator 6 through the cooperation of the connecting ball head 74 and the ball bushing 75. This allows the two ends of the electric cylinder 71 to be adjusted more flexibly, increases the adjustment angle of the rapid radiator 6, and provides precise heat dissipation for areas with severe local heat generation.

[0031] In this embodiment, the electric cylinder 71 is provided with a ball head holder 72 at one end near the fixed ball head 73, and the fixed ball head 73 is engaged with the ball head holder 72, while the other side of the ball head holder 72 is fixedly connected to the transformer room door 2.

[0032] Furthermore, the rapid heat sink 6 includes a hollow frame 61, on which spherical slots 64 corresponding to spherical bushings 75 are arranged in a rectangular array, and the spherical bushings 75 are engaged with the inner side of the spherical slots 64.

[0033] Furthermore, a cooling fan 62 is fixedly connected to the hollow frame 61, and a connecting hose 63 is fixedly connected to one end of the cooling fan 62 away from the hollow frame 61, and the other end of the connecting hose 63 is fixedly connected to the air intake filter 4.

[0034] By adopting the above technical solution, the orientation and posture of the hollow frame 61 can be adjusted by the electric cylinders 71 arranged in a rectangular array. The output rod position of each electric cylinder 71 is different, and the orientation of the cooling fan 62 in the hollow frame 61 is also different. By changing the orientation of the cooling fan 62, the airflow can be blown directly to the local heat-generating position after entering, thereby quickly cooling the severely heated position.

[0035] Furthermore, the high-voltage electrical room isolation plate 1 and the low-voltage electrical room isolation plate 3 divide the inner side of the steel structure frame 8 into three parts, which are, from left to right, the low-voltage distribution room 31, the transformer installation room 21, and the high-voltage distribution room 11.

[0036] Furthermore, a rain shelter roof 5 is fixedly connected above the steel structure frame 8, and the rain shelter roof 5 covers the low-voltage distribution room 31, the transformer installation room 21 and the high-voltage distribution room 11 respectively. The side of the high-voltage power room isolation plate 1 and the side of the low-voltage power room isolation plate 3 are respectively provided with wire-passing grooves.

[0037] The working principle of this utility model is as follows: In use, external airflow is first introduced through the cooperation of cooling fan 62 and connecting hose 63. The external airflow passes through air intake filter 4 and blows onto the transformer surface inside transformer installation chamber 21. Temperature sensor in transformer installation chamber 21 transmits data to external computer, which transmits signal to controller 65. Controller 65 controls the extension and retraction of output rod of electric cylinder 71. By controlling the extension and retraction length of the output rod of each group of four electric cylinders 71 to be different, the orientation of hollow frame 61 is different, thereby adjusting the direction of airflow blown by cooling fan 62. This allows the airflow to directly blow onto the locally hot areas of the transformer, precisely cooling the locally hot areas and thus rapidly dissipating heat from the transformer. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
