Description

Technical Field

[0001] This invention belongs to the field of transformer technology, specifically a transformer with lightning protection components. Background Technology

[0002] A transformer is a static electrical device used to transform AC voltage and current to transmit AC electrical energy. Currently, transformers used outdoors need to be equipped with lightning protection components so that when the transformer is struck by lightning, the lightning current can be conducted to the ground through the lightning protection components, thereby achieving the safety protection of the transformer.

[0003] Most existing transformer lightning protection components include lightning rods, which are fixed and erected on the top of the transformer to guide the lightning current to the ground through corresponding conductors. However, since the probability of a transformer being struck by lightning is relatively low, the probability of the lightning rods functioning is also relatively low. When the lightning rods are erected on the top of the transformer for a long time, they are not only easily affected by strong winds and may be bent or loose, but they are also prone to accumulating a lot of dust and debris, which affects their effectiveness. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a transformer with lightning protection components.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A transformer with lightning protection components includes a transformer body, a telescopic protective pipe, a first drive assembly, a second drive assembly, and a lightning rod.

[0007] The lightning rod is movably mounted on the side of the transformer body, and is grounded via a grounding wire.

[0008] The telescopic protective fitting is movably sleeved on the outside of the lightning rod.

[0009] The first drive assembly and the second drive assembly are mounted on the side wall of the transformer body.

[0010] When the lightning rod is required to function, the second drive component causes the telescopic protective tube to shorten, so that the telescopic protective tube is removed from the outside of the lightning rod. Then, the first drive component causes the lightning rod to rotate, so that the lightning rod extends vertically toward the transformer body.

[0011] As a further improvement of the present invention: the first driving component includes a first incomplete gear, a support plate, a second incomplete gear, and a motor.

[0012] The bracket plate is fixedly mounted on the side wall of the transformer body, the motor is fixedly mounted on one side of the bracket plate, the second incomplete gear is fixedly mounted on the output shaft of the motor, the first incomplete gear is rotatably mounted on the side wall of the bracket plate and can mesh with the second incomplete gear, and the lightning rod is fixedly mounted on the circumferential side wall of the first incomplete gear.

[0013] As a further improvement of the present invention: the telescopic protective pipe fitting includes a telescopic pipe, a fixed base, and a sliding base.

[0014] The fixed seat is fixedly installed on the side wall of the transformer body, and the sliding seat is slidably installed on the side wall of the transformer body. The sliding seat and the fixed seat are distributed opposite to each other. One end of the telescopic tube is connected to the fixed seat, and the other end is connected to the sliding seat. The sliding seat has a through hole that allows the lightning rod to extend into the telescopic tube.

[0015] As a further improvement of the present invention: a guide wheel is rotatably provided on the side wall of the transformer body.

[0016] The second drive assembly includes a reel and a pull rope.

[0017] The reel is fixedly mounted on the output shaft of the motor. One end of the pull rope is connected to the reel, and the other end passes around the guide wheel and is connected to the sliding seat.

[0018] As a further improvement of the present invention: a guide rail is also fixedly provided on the side wall of the transformer body, and the sliding seat slides in cooperation with the guide rail.

[0019] As a further improvement of the present invention: the sliding seat and the fixed seat are connected by an elastic element, which provides elastic support for the sliding seat.

[0020] As a further improvement of the present invention, a flexible cleaning ring is also provided on the inner wall of the through hole.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In this embodiment of the invention, when the lightning rod is not required to perform its lightning protection function, it is stored horizontally on the side of the transformer body. A telescopic protective sleeve is fitted over the lightning rod to protect it, preventing dust and other foreign matter from contaminating it and extending its service life. Furthermore, the horizontal distribution of the lightning rod reduces wind resistance, thus lowering the probability of it loosening or bending due to strong winds and improving its effectiveness. When the lightning rod is required to perform its lightning protection function, the second drive assembly shortens the telescopic protective sleeve, removing it from the outside of the lightning rod to expose it. Then, the first drive assembly rotates the lightning rod, causing it to extend vertically above the transformer body, thus performing its lightning protection function. Compared to existing technologies, this invention achieves secure storage and protection of the lightning rod when it is not required, while also reducing the impact of strong winds and extending its service life.

Detailed Implementation

[0028] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Please see Figure 1 as well as Figure 2 This embodiment provides a transformer with lightning protection components, including a transformer body 10, a telescopic protective tube 20, a first drive assembly 30, a second drive assembly 40, and a lightning rod 50. The lightning rod 50 is movably disposed on the side of the transformer body 10 and is grounded through a grounding wire (not shown in the figure). The telescopic protective tube 20 is movably sleeved on the outside of the lightning rod 50. The first drive assembly 30 and the second drive assembly 40 are installed on the side wall of the transformer body 10. When the lightning rod 50 needs to function, the second drive assembly 40 drives the telescopic protective tube 20 to shorten, so that the telescopic protective tube 20 is removed from the outside of the lightning rod 50. Subsequently, the first drive assembly 30 drives the lightning rod 50 to rotate, so that the lightning rod 50 extends vertically above the transformer body 10.

[0031] When the lightning rod 50 is not needed for lightning protection, it is stored on the side of the transformer body 10 and kept horizontally distributed. The telescopic protective tube 20 is sleeved on the outside of the lightning rod 50 to protect it from dust and other foreign objects, thus extending its service life. Furthermore, the horizontal distribution of the lightning rod 50 reduces wind resistance, thereby lowering the probability of it loosening or bending due to strong winds and improving its effectiveness. When the lightning rod 50 is needed for lightning protection, the second drive assembly 40 shortens the telescopic protective tube 20, removing it from the outside of the lightning rod 50 and exposing it. Then, the first drive assembly 30 rotates the lightning rod 50, causing it to extend vertically above the transformer body 10, thus fulfilling its lightning protection function.

[0032] Please see Figure 1 as well as Figure 2In one embodiment, the first drive assembly 30 includes a first incomplete gear 301, a support plate 302, a second incomplete gear 303, and a motor 304. The support plate 302 is fixedly disposed on the side wall of the transformer body 10. The motor 304 is fixedly mounted on one side of the support plate 302. The second incomplete gear 303 is fixedly disposed on the output shaft of the motor 304. The first incomplete gear 301 is rotatably disposed on the side wall of the support plate 302 and can mesh with the second incomplete gear 303. The lightning rod 50 is fixedly disposed on the circumferential side wall of the first incomplete gear 301.

[0033] When the lightning rod 50 is required to perform its lightning protection function, the motor 304 is started. The output shaft of the motor 304 drives the second incomplete gear 303 to rotate. At this time, the second drive assembly 40 drives the telescopic protective tube 20 to shorten, so that the telescopic protective tube 20 is removed from the outside of the lightning rod 50. After the telescopic protective tube 20 is removed from the outside of the lightning rod 50, the second incomplete gear 303 meshes with the first incomplete gear 301, thereby driving the first incomplete gear 301 to rotate. When the first incomplete gear 301 rotates, it drives the lightning rod 50 to rotate, so that the horizontally distributed lightning rod 50 rotates to a vertical state and extends above the transformer body 10, thereby performing its lightning protection function.

[0034] Please see Figure 1 , Figure 2 as well as Figure 4 In one embodiment, the telescopic protective fitting 20 includes a telescopic tube 201, a fixed seat 202, and a sliding seat 204. The fixed seat 202 is fixedly disposed on the side wall of the transformer body 10, and the sliding seat 204 is slidably disposed on the side wall of the transformer body 10. The sliding seat 204 and the fixed seat 202 are distributed opposite to each other. One end of the telescopic tube 201 is connected to the fixed seat 202, and the other end is connected to the sliding seat 204. The sliding seat 204 has a through hole for the lightning rod 50 to extend into the telescopic tube 201.

[0035] When the lightning rod 50 is not needed for lightning protection, the sliding seat 204 is located away from the fixed seat 202. The end of the lightning rod 50 away from the first incomplete gear 301 extends from the through hole into the telescopic tube 201, and the telescopic tube 201 covers the lightning rod 50 to achieve protection. When the lightning rod 50 is needed for lightning protection, the second drive assembly 40 drives the sliding seat 204 to slide along the side wall of the transformer body 10 toward the fixed seat 202. The telescopic tube 201 is compressed and shortened. After the sliding seat 204 moves out from one end of the lightning rod 50, the second incomplete gear 303 and the first incomplete gear 301 enter a meshing state, thereby driving the lightning rod 50 to rotate, so that the lightning rod 50 extends vertically above the transformer body 10 to perform lightning protection.

[0036] Please see Figure 1 as well as Figure 3 In one embodiment, a guide wheel 102 is rotatably disposed on the side wall of the transformer body 10. The second drive assembly 40 includes a reel 401 and a pull rope 402. The reel 401 is fixedly disposed on the output shaft of the motor 304. One end of the pull rope 402 is connected to the reel 401, and the other end passes around the guide wheel 102 and is connected to the sliding seat 204.

[0037] While the motor 304 drives the second incomplete gear 303 to rotate through its output shaft, the output shaft of the motor 304 can also drive the reel 401 to rotate. When the reel 401 rotates, it winds up the pull rope 402. When the pull rope 402 winds up, it pulls the sliding seat 204, causing the sliding seat 204 to slide along the side wall of the transformer body 10 and approach the fixed seat 202. When the sliding seat 204 slides, it drives the telescopic tube 201 to shorten until the lightning rod 50 is fully exposed. When the lightning rod 50 is fully exposed, the rotating second incomplete gear 303 meshes with the first incomplete gear 301, thereby driving the lightning rod 50 to rotate, so that the lightning rod 50 extends vertically above the transformer body 10.

[0038] Please see Figure 1 In one embodiment, a guide rail 101 is also fixedly provided on the side wall of the transformer body 10, and the sliding seat 204 slides in cooperation with the guide rail 101.

[0039] When the pull rope 402 pulls the sliding seat 204, the sliding seat 204 slides along the guide rail 101 and approaches the fixed seat 204, thereby driving the telescopic tube 201 to shorten.

[0040] Please see Figure 1 as well as Figure 3 In one embodiment, the sliding seat 204 and the fixed seat 202 are connected by an elastic element 203, which provides elastic support for the sliding seat 204.

[0041] When the motor 304 rotates, it drives the reel 401 to rotate and wind up the pull rope 402. The pull rope 402 pulls the sliding seat 204, causing the sliding seat 204 to move closer to the fixed seat 202. At this time, the elastic element 203 is gradually compressed. After the lightning rod 50 performs its lightning protection function, the motor 304 drives the second incomplete gear 303 and the reel 401 to rotate in the opposite direction. When the second incomplete gear 303 rotates in the opposite direction, it drives the first incomplete gear 301 to rotate in the opposite direction through its reverse meshing, thereby driving the lightning rod 50 to rotate in the opposite direction. When the reel 401 rotates in the opposite direction, it unwinds the pull rope 402. The elastic element 203 pushes the sliding seat 204 away from the fixed seat 202. The sliding seat 204 pulls the telescopic tube 201 to extend it. When the lightning rod 50 rotates back to the horizontal position, the second incomplete gear 303 disengages from the first incomplete gear 301. As the reel 401 continues to reverse, the elastic element 203 continues to push the sliding seat 204 away from the fixed seat 202. The sliding seat 204 is re-sleeved on the outside of the lightning rod 50 and moves along the outside of the lightning rod 50, thereby pulling the telescopic tube 201 so that the telescopic tube 201 is re-sleeved on the outside of the lightning rod 50 to provide further protection for the lightning rod 50.

[0042] In one embodiment, the elastic element 203 can be a spring or a metal sheet, and there is no limitation here.

[0043] In one embodiment, the telescopic tube 201 may be composed of a rubber corrugated tube or a series of tube sections connected in sequence; no limitation is made here.

[0044] Please see Figure 4 In one embodiment, a flexible cleaning ring 205 is also provided on the inner wall of the through hole.

[0045] When the motor 304 drives the reel 401 to reverse, the elastic element 203 pushes the sliding seat 204 so that the sliding seat 204 moves along the outside of the lightning rod 50. The flexible cleaning ring 205 can act on the outer wall of the lightning rod 50, thereby pushing away the rainwater, dust and other debris attached to the surface of the lightning rod 50, thus cleaning the rainwater, dust and other debris.

[0046] In one embodiment, the flexible cleaning ring 205 can be a rubber ring or a silicone ring, and there is no limitation here.

[0047] In this embodiment of the invention, when the lightning rod 50 is not required to perform its lightning protection function, the lightning rod 50 is stored on the side of the transformer body 10 and kept horizontally distributed. The telescopic protective tube 20 is sleeved on the outside of the lightning rod 50 to protect the lightning rod 50, prevent the lightning rod 50 from being contaminated with dust and other foreign objects, and improve the service life of the lightning rod 50. Furthermore, the horizontal distribution of the lightning rod 50 also reduces the wind resistance it experiences, thereby reducing the probability of the lightning rod 50 loosening or bending due to strong winds, thus improving the effectiveness of the lightning rod 50. When the lightning rod 50 is required to perform its lightning protection function... When the lightning rod 50 is in operation, the telescopic protective tube 20 is shortened by the second drive component 40, so that the telescopic protective tube 20 is removed from the outside of the lightning rod 50 to expose the lightning rod 50. Then, the first drive component 30 drives the lightning rod 50 to rotate, so that the lightning rod 50 extends vertically above the transformer body 10, thereby performing the lightning protection function. Compared with the prior art, when the lightning rod 50 does not need to perform the lightning protection function, the lightning rod 50 can be stored and protected, while reducing the impact of strong winds on the lightning rod 50 and extending the service life of the lightning rod 50.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
