Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and specifically relates to a collision-proof voltage transformer. Background Technology

[0002] A voltage transformer is an electrical device that works based on the principle of electromagnetic induction. It is used to convert high voltage in a power system into a standard low voltage proportionally, providing a safe and isolated voltage signal for measuring instruments and relay protection devices, and realizing electrical isolation between the high voltage system and secondary equipment.

[0003] Voltage transformers contain precision iron cores, windings, and insulation components. External impacts can cause iron core displacement, winding deformation, or insulation damage, affecting measurement accuracy and even causing short-circuit faults. Voltage transformers installed outdoors or in industrial locations are susceptible to accidental impacts such as vehicle collisions and equipment handling, and therefore require physical protection.

[0004] In the prior art, Chinese utility model patent document CN215644073U discloses a voltage transformer with an anti-collision mechanism; and Chinese utility model patent document CN222507329U discloses an anti-collision structure for a voltage transformer. The above-mentioned prior art requires a protective cover (sleeve) to be installed on the outside of the voltage transformer, which closes the sides or top of it and affects the heat dissipation of the voltage transformer.

[0005] Therefore, it is necessary to design a collision-resistant voltage transformer that provides physical protection for the voltage transformer, buffers and absorbs energy when a collision occurs, and allows the sides and top of the voltage transformer body to be connected to the outside for heat dissipation, in order to solve the current technical problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, this utility model provides a voltage transformer that provides physical protection for the voltage transformer, buffers and absorbs energy when a collision occurs, and allows the sides and top of the voltage transformer body to be connected to the outside for heat dissipation.

[0007] The technical solution of this utility model is as follows: a collision-proof voltage transformer, including an inner support, the inner support having a base plate, a support frame provided above the base plate, and upright plates provided around the base plate. The support frame is fixedly connected to the top of the upright plates, and the voltage transformer body is centrally located at the top of the base plate. A longitudinal support plate is mounted on the side of the upright plates opposite to the voltage transformer body via an elastic support mechanism. Horizontal support rods perpendicular to the longitudinal support plate are evenly arranged on the longitudinal support plate, and a buffer strip is fixedly mounted on the side of the horizontal support rod opposite to the longitudinal support plate.

[0008] Furthermore, the elastic support mechanism has a sleeve fixedly installed on one side of the upright plate. A retaining edge is provided on the inner side of the end of the sleeve facing away from the upright plate. A slider is slidably installed inside the sleeve. A support rod fixedly connected to the longitudinal support plate is fixedly installed on one side of the slider. A spring is provided between the other side of the slider and the inner end of the sleeve.

[0009] Furthermore, a frame plate is fixedly installed on the sleeve, a limit switch is centrally installed on the frame plate, and a trigger plate matching the limit switch is installed on the longitudinal support plate; a controller is connected to the limit switch, an audible and visual alarm is connected to the controller, and the audible and visual alarm is fixedly installed on the top of the longitudinal support plate.

[0010] Furthermore, a mounting plate integrally formed with the horizontal support rod is fixedly installed on one side of the horizontal support rod, and the mounting plate is detachably and fixedly assembled to one side of the vertical support plate by bolts.

[0011] Furthermore, a T-slot is provided on the side of the horizontal support rod away from the longitudinal support plate, and a T-block matching the T-slot is provided on one side of the buffer strip.

[0012] Furthermore, the buffer strip has a cavity inside.

[0013] Furthermore, both ends of the horizontal support rod are bent at least 90° toward the voltage transformer body.

[0014] The beneficial effects of this utility model are:

[0015] (1) In this utility model, the elastic support mechanism and the longitudinal support plate provide elastic support for the horizontal support rod. When the vehicle or equipment is hit by an accidental collision, the vehicle or equipment comes into contact with the buffer strip on the outside of the horizontal support rod. The buffer strip deforms and the elastic support mechanism is compressed at the same time, converting part of the impact energy into the elastic potential energy of the buffer strip and the elastic support mechanism, thereby achieving the purpose of buffering and protecting the main body of the voltage transformer.

[0016] (2) There is a certain gap between the horizontal support rods, which can ensure the air circulation around and top of the voltage transformer body. Compared with the existing technology of enclosing the voltage transformer body, it can help the voltage transformer body dissipate heat during operation.

[0017] (3) The inner support provides support for the buffer mechanism such as the elastic support mechanism, longitudinal support plate and transverse support rod, while the inner support and the voltage transformer body have a certain gap around them, which can further reduce the impact transmitted to the voltage transformer body during impact.

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are not intended to limit the present invention or its application or use in any way. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0026] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] like Figures 1 to 7As shown, the anti-collision voltage transformer includes an inner support 2, which has a base plate 21. A support frame 22 is provided above the base plate 21, and upright plates 23 are provided around the base plate 21. The support frame 22 is fixedly connected to the top of the upright plates 23, and the voltage transformer body 1 is centrally located at the top of the base plate 21. A longitudinal support plate 4 is mounted on the side of the upright plate 23 away from the voltage transformer body 1 through an elastic support mechanism 3. Horizontal support rods 5 are evenly arranged on the longitudinal support plate 4 and perpendicular to it. A buffer strip 6 is fixedly provided on the side of the horizontal support rod 5 away from the longitudinal support plate 4. In this embodiment, the elastic support mechanism 3 and the longitudinal support plate 4 provide elastic support for the horizontal support rod 5. When subjected to accidental collisions such as vehicle impacts or equipment handling, the vehicle, equipment, and the outer side of the horizontal support rod 5 are protected. When the buffer bar 6 comes into contact with the voltage transformer body 1, the buffer bar 6 deforms, and the elastic support mechanism 3 is compressed, converting part of the impact energy into the elastic potential energy of the buffer bar 6 and the elastic support mechanism 3, thereby achieving the purpose of buffering and protecting the voltage transformer body 1. There is a certain gap between the horizontal support rods 5, which can ensure air circulation around and on the top of the voltage transformer body 1. Compared with the existing technology of enclosing the voltage transformer body 1, this is conducive to heat dissipation of the voltage transformer body 1 during operation. The inner bracket 2 provides support for the buffer mechanism such as the elastic support mechanism 3, the longitudinal support plate 4 and the horizontal support rods 5, and there is a certain gap between the inner bracket 2 and the voltage transformer body 1, which can further reduce the impact transmitted to the voltage transformer body 1 during the impact.

[0028] In some embodiments, such as Figure 5 and 7 As shown, the elastic support mechanism 3 has a sleeve 31 fixedly installed on one side of the vertical plate 23. A retaining edge 34 is provided on the inner side of the end of the sleeve 31 facing away from the vertical plate 23. A slider 33 is slidably installed inside the sleeve 31. A support rod 32 fixedly connected to the longitudinal support plate 4 is fixedly installed on one side of the slider 33. A spring 32 is provided between the other side of the slider 33 and the inner end of the sleeve 31. When a collision occurs, the horizontal support rod 5 pushes the longitudinal support plate 4 to move. The longitudinal support plate 4 drives the support rod 32 and the slider 33 to move, compressing the spring 32 and converting part of the impact energy into the elastic potential energy of the spring 32, thereby achieving the purpose of buffering.

[0029] In some embodiments, such as Figure 3As shown, a support plate 7 is fixedly installed on the sleeve 31, and a limit switch 8 is centrally located on the support plate 7. A trigger plate 41 matching the limit switch 8 is installed on the longitudinal support plate 4. A controller is connected to the limit switch 8, and an audible and visual alarm 9 is connected to the controller. The audible and visual alarm 9 is fixedly installed on the top of the longitudinal support plate 4. When a collision occurs, the elastic support mechanism 3 is compressed, and the longitudinal support plate 4 is close to the limit switch 8. When the impact force is slight, the compression of the elastic support mechanism 3 is small, and the trigger plate 41 will not trigger the limit switch 8. When the impact force is large, the compression of the elastic support mechanism 3 is large, and the trigger plate 41 will trigger the limit switch 8. After the controller detects that the limit switch 8 has been triggered, it turns on the audible and visual alarm 9, which emits an audible and visual alarm to remind relevant personnel to detect the collision in time.

[0030] In some embodiments, such as Figure 5 and 6 As shown, a mounting plate 51, which is an integral part of the horizontal support rod 5, is fixedly installed on one side of the horizontal support rod 5. The mounting plate 51 is detachably and fixedly assembled to one side of the longitudinal support plate 4 by bolts. In the event of a collision, after the horizontal support rod 5 is deformed and damaged by the collision, the horizontal support rod 5 can be removed and replaced by removing the bolts, which is convenient for maintenance.

[0031] In some embodiments, a T-slot 52 is provided on the side of the horizontal support rod 5 away from the longitudinal support plate 4, and a T-block 62 matching the T-slot 52 is provided on one side of the buffer strip 6; the T-block 62 and the buffer strip 6 are an integral structure, and the T-block 62 is snapped into the inside of the T-slot 52, so that it can be disassembled and replaced when the buffer strip 6 is damaged.

[0032] In some embodiments, the buffer strip 6 has a cavity 61 inside, which provides additional deformation space for the buffer strip 6 when it is compressed.

[0033] In some embodiments, both ends of the crossbar 5 are bent at least 90° toward the voltage transformer body 1; the bending design eliminates sharp corners and significantly reduces the probability of collision objects being punctured.

[0034] Specifically, both ends of the horizontal support rod 5 are bent at 90° toward the voltage transformer body 1.

[0035] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0036] The embodiments described above only illustrate some implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
