Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer with lead-out devices. Background Technology

[0002] A transformer generally refers to a power transformer, which is a static electrical device used to convert an alternating voltage (current) of a certain value into one or more different values ​​of voltage (current) at the same frequency. It is a static device with two or more windings. In order to transmit electrical energy, it converts the alternating voltage and current of one system into the voltage and current of another system through electromagnetic induction at the same frequency. Usually, the values ​​of these currents and voltages are different. Transformers are mainly installed in the open air, in the field, or in areas prone to lightning strikes. In the event of severe weather, they are easily struck by lightning.

[0003] Patent document CN219591216U discloses a transformer with an output device, including a transformer body. The transformer body has a rainproof top plate, and a lightning rod is installed on the top of the rainproof top plate. Support legs are fixedly installed at the four corners of the top of the transformer body, and the tops of the support legs are fixedly connected to the rainproof top plate. A conductive sleeve is fixedly installed on the inner side of the top of the rainproof top plate. In the aforementioned application, a conductive rod is inserted into the conductive sleeve through a snap-fit ​​hole at the top of the rainproof top plate, and a locking pin is snapped into a locking groove. After the locking pin is snapped into the bottom of the locking groove, rotating the lightning rod causes the conductive rod and locking pin to rotate, snapping the locking pin into the snap-fit ​​part. The snap-fit ​​part locks the locking pin, and a compression spring applies elastic force to the conductive rod, thus fixing the lightning rod to the top of the rainproof top plate. However, this method is cumbersome to install the lightning rod, requiring the locking pin to be aligned with the locking groove and inserted, which is time-consuming and labor-intensive, hindering installation and subsequent maintenance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a transformer with a lead-out device, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer with a lead-out device, comprising a transformer body, a mounting plate fixedly connected to the top of the transformer body, a support leg fixedly mounted to the top of the mounting plate by bolts, a rainproof top plate fixedly connected to the top of the support leg, and a lead-out device mounting mechanism provided on the top of the rainproof top plate; the lead-out device mounting mechanism includes a mounting cylinder, a lightning rod, and a mounting housing, the mounting cylinder penetrating and fixedly connected to the top of the rainproof top plate, a grounding wire provided on the side of the mounting cylinder, a sealing ring provided on the top of the mounting cylinder, a pressure ring provided on the surface of the lightning rod, a threaded post fixedly connected to the bottom of the lightning rod, the threaded post being threadedly connected to the inside of the mounting housing, and the mounting housing... The surface has an annular groove, and the inner wall of the mounting cylinder has a groove. A telescopic spring is installed inside the groove, and an arc-shaped block A is slidably connected inside the groove through the telescopic spring. An air pressure chamber is connected through and fixedly to the side of the mounting cylinder. The end of the air pressure chamber away from the mounting cylinder is connected through and fixedly to the bottom of the rainproof top plate. A piston rod A is slidably connected to the piston inside one end of the air pressure chamber, and a piston rod B is slidably connected to the piston inside the other end of the air pressure chamber. The end of the piston rod B away from the air pressure chamber is fixedly connected to the arc-shaped block A. A deceleration ring is fixedly connected to the inner wall of the mounting cylinder. A pop-out spring is installed at the bottom of the mounting cylinder. A deceleration mechanism and a rotating assembly are installed at the bottom of the mounting housing. A water removal mechanism is installed inside the mounting cylinder.

[0006] According to the above technical solution, there are four sets of support legs, and all four sets of support legs are made of nylon material. All four sets of support legs are made of insulating nylon material, so that voltage will not be transmitted to the transformer body through the support legs.

[0007] According to the above technical solution, the longitudinal width of the groove is equal to the longitudinal width of the annular slot, and half of the arc-shaped block A is initially located inside the annular slot. The pop-out spring is initially in a compressed state, and the arc-shaped block A is stuck in the annular slot, making it impossible for the mounting housing to detach from the mounting cylinder.

[0008] According to the above technical solution, the arc surface of the arc block A faces upward, and the lateral length of the groove is greater than the lateral length of the arc block A. When the arc surface of the arc block A is squeezed, it will move into the groove, and the arc block A can be completely retracted into the groove.

[0009] According to the above technical solution, the deceleration mechanism includes a connecting plate, the top of the connecting plate is fixedly connected to the bottom of the mounting housing, a rotating shaft is rotatably connected to the side of the connecting plate, a contact rod is fixedly connected to the side of the rotating shaft, an elastic rope is fixedly connected to the top of the contact rod, the end of the elastic rope away from the contact rod is fixedly connected to the connecting plate, and a limit rod is fixedly connected to the side of the connecting plate.

[0010] According to the above technical solution, the lateral length of the contact rod is greater than the distance from the rotating shaft surface to the deceleration ring. The contact rod is made of rubber. When the contact rod moves upward, it will contact the deceleration ring. When the rubber contact rod is squeezed against the deceleration ring, resistance will be generated.

[0011] According to the above technical solution, the water removal mechanism includes a water tank. Return springs are provided on both sides of the interior of the water tank. Piston plates are slidably connected to both sides of the interior of the water tank via two sets of return spring pistons. Two sets of water inlet pipes are connected through and fixedly to the top of the water tank. Two sets of water outlet pipes are connected through and fixedly to the bottom of the water tank. One-way valves are provided inside both the water inlet and outlet pipes. A toothed rod is fixedly connected to the side of each set of piston plates that is close to the other. The end of the water inlet pipe furthest from the water tank is connected through and fixedly to the bottom of the mounting cylinder. The end of the water outlet pipe furthest from the water tank is connected through and fixedly to the bottom of the rainproof top plate.

[0012] According to the above technical solution, the rotating component includes a circular groove and a rotating rod. The circular groove is formed at the bottom of the mounting housing, and an embedding groove is formed on the inner wall of the circular groove. The rotating rod passes through and is rotatably connected to the top of the water tank. A rotating gear is fixedly connected to the bottom of the rotating rod, and a circular block is fixedly connected to the top of the rotating rod. Grooves are formed on both sides of the circular block. A compression spring is provided inside the groove, and an arc-shaped block B is slidably connected inside the groove through the compression spring.

[0013] According to the above technical solution, in the initial state, half of the arc-shaped block B is located in the embedding groove, and the number of the embedding grooves is set to ten. When the arc-shaped block B is stuck in the embedding groove, the rotating rod will rotate synchronously when the housing is rotated. The setting of ten embedding grooves can ensure that the arc-shaped block B is stuck in at various angles.

[0014] According to the above technical solution, the teeth on the rack are matched with the teeth on the rotating gear, and the rotating gear is an incomplete gear. When the rotating gear rotates and its teeth mesh with the teeth on the rack, it will drive the rack and piston plate to move.

[0015] This invention provides a transformer with a lead-out device. It has the following advantages:

[0016] (1) By setting the lead-out device installation mechanism, the present invention enables the lightning rod to be firmly installed on the top of the rainproof roof plate through the cooperation of components such as lightning rod, threaded column, mounting housing, mounting cylinder, and lead-out ground wire, thereby realizing lightning protection for the main body of the transformer. When it is necessary to inspect the lightning rod, the mounting housing can be lifted upward by pulling up the piston rods A on both sides. At this time, the mounting housing and the lightning rod can be removed to facilitate subsequent maintenance work.

[0017] (2) By setting up a deceleration mechanism, the present invention enables the installation housing to move upward when the piston rods A on both sides are pulled upward and the spring rebounds, and the installation housing moves upward. The speed of the installation housing rising upward is slowed down by the cooperation of components such as the rotating shaft, contact rod, elastic rope, and deceleration ring, so as to prevent the rising speed from hitting the staff or damaging the lightning rod. When the installation housing is inserted downward into the installation cylinder, there will be no great resistance to affect the installation of the lightning rod.

[0018] (3) By setting up a water removal mechanism, when water is found at the bottom of the installation cylinder, the lightning rod is rotated to drive the installation housing to rotate. The rotation of the installation housing will drive the rotating rod to rotate synchronously through the cooperation of the arc block B and the embedded groove. The rotation of the rotating rod will drive the rotating gear to rotate. The rotation of the rotating gear will drive the piston plate to move repeatedly, so that the negative pressure is repeatedly formed on both sides of the water tank. Thus, the water inside the installation cylinder is sucked away through the water inlet pipe and discharged to the rainproof top plate through the water outlet pipe. This facilitates the treatment of water inside the installation cylinder and prevents water from affecting the lightning protection of the transformer body. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1-8One embodiment of the present invention is as follows: a transformer with a lead-out device includes a transformer body 1, a mounting plate 2 is fixedly connected to the top of the transformer body 1, a support leg 3 is fixedly installed on the top of the mounting plate 2 by bolts, a total of four sets of support legs 3 are provided, and the material of the four sets of support legs 3 is nylon material. The four sets of support legs 3 are all made of insulating nylon material, so that voltage will not be transmitted to the transformer body 1 through the support legs 3. A rainproof top plate 4 is fixedly connected to the top of the support legs 3, and a lead-out device mounting mechanism 5 is provided on the top of the rainproof top plate 4.The lightning rod installation mechanism 5 includes an installation cylinder 51, a lightning rod 54, and an installation housing 57. The installation cylinder 51 is connected to the top of the rainproof roof plate 4. A grounding wire 52 is provided on the side of the installation cylinder 51, and a sealing ring 53 is provided on the top of the installation cylinder 51. A pressure ring 55 is provided on the surface of the lightning rod 54, and a threaded post 56 is fixedly connected to the bottom of the lightning rod 54. The threaded post 56 is threadedly connected to the inside of the installation housing 57. An annular groove 58 is provided on the surface of the installation housing 57, and a groove 59 is provided on the inner wall of the installation cylinder 51. A telescopic spring 510 is provided inside the groove 59, and the inside of the groove 59 is slidably connected by the telescopic spring 510. An arc-shaped block A511 is provided, with its arc surface facing upwards. The lateral length of the groove 59 is greater than the lateral length of the arc-shaped block A511. When the arc surface of the arc-shaped block A511 is compressed, it will move into the groove 59, allowing it to retract completely into the groove 59. A pressure chamber 512 is connected through and fixedly to the side of the mounting cylinder 51. The end of the pressure chamber 512 away from the mounting cylinder 51 is connected through and fixedly to the bottom of the rainproof top plate 4. A piston rod A513 is slidably connected to the piston inside one end of the pressure chamber 512, and a piston rod B514 is slidably connected to the piston inside the other end of the pressure chamber 512. The piston rod B514 is located away from the pressure chamber 512. The end is fixedly connected to the arc-shaped block A511. A deceleration ring 515 is fixedly connected to the inner wall of the mounting cylinder 51. A pop-out spring 516 is provided at the bottom of the interior of the mounting cylinder 51. The longitudinal width of the groove 59 is equal to the longitudinal width of the annular groove 58. In the initial state, half of the arc-shaped block A511 is located inside the annular groove 58. In the initial state, the pop-out spring 516 is in a compressed state. The arc-shaped block A511 is stuck in the annular groove 58, preventing the mounting housing 57 from detaching from the mounting cylinder 51. A deceleration mechanism 6 and a rotating assembly 8 are provided at the bottom of the mounting housing 57. A water removal mechanism 7 is provided inside the mounting cylinder 51. The deceleration mechanism 6 includes a connecting plate 6. 1. The top of the connecting plate 61 is fixedly connected to the bottom of the mounting housing 57. A rotating shaft 62 is rotatably connected to the side of the connecting plate 61. A contact rod 63 is fixedly connected to the side of the rotating shaft 62. An elastic rope 64 is fixedly connected to the top of the contact rod 63. The end of the elastic rope 64 away from the contact rod 63 is fixedly connected to the connecting plate 61. A limit rod 65 is fixedly connected to the side of the connecting plate 61. The lateral length of the contact rod 63 is greater than the distance from the surface of the rotating shaft 62 to the deceleration ring 515. The contact rod 63 is made of rubber. When the contact rod 63 moves upward, it will contact the deceleration ring 515. When the rubber contact rod 63 is squeezed against the deceleration ring 515, resistance will be generated.

[0031] In use, during severe weather, the support leg 3 isolates the lightning rod 54 from the transformer body 1, preventing electrical conduction between them. The lightning rod 54 transmits electricity through the threaded post 56 to the mounting housing 57, which in turn transmits it to the mounting cylinder 51, and finally to the ground via the grounding wire 52, thus achieving lightning protection. When the lightning rod 54 needs to be disassembled for maintenance, the piston rods A513 on both sides are pulled upwards. At this time, the air pressure in the air chamber 512 will drive the piston rod B514 to move, causing the arc-shaped block A511 to leave the annular groove 58 and retract into the groove 59. Inside, when the telescopic spring 510 is compressed and the arc-shaped block A511 leaves the annular groove 58 and loses its restraint on the mounting housing 57, the pop-out spring 516 will rebound, causing the mounting housing 57 to pop upwards. The groove 59 will then misalign with the annular groove 58. At this point, the piston rod A513 will be released, and the telescopic spring 510 will rebound, causing the arc-shaped block A511 to pop out. The piston rods A513 and B514 will then move back to their original positions. Finally, the mounting housing 57 and the lightning rod 54 can be removed. Rotating the lightning rod 54 will separate its bottom threaded post 56 from the mounting housing 57. When reinstalling, the bottom threaded post 56 of the lightning rod 54 will be rotated... The mounting housing 57 is inserted downwards into the mounting cylinder 51. The spring 516 is gradually compressed. Initially, the arc surface of the arc-shaped block A511 is compressed by the bottom of the mounting housing 57 and retracts into the groove 59, tightening the telescopic spring 510. When the groove 59 fits into the annular slot 58, the telescopic spring 510 rebounds, causing the arc-shaped block A511 to engage with the annular slot 58. At this point, the mounting housing 57 can no longer leave the mounting cylinder 51 to complete the installation of the lightning rod 54. As the mounting housing 57 is inserted downwards into the mounting cylinder 51, the connecting plate 61 moves downwards, causing the contact rod 63 to move downwards. When the contact rod 63 contacts the deceleration ring 515, it will deflect upwards and will not exert too much pressure on the deceleration ring 515, thus avoiding resistance. Subsequently, the elastic rope 64 drives the contact rod 63 to return to its original position. When the pop-out spring 516 rebounds and causes the mounting housing 57 to pop up, the connecting plate 61 moves upwards, causing the contact rod 63 to move upwards again and contact the deceleration ring 515. At this time, due to the presence of the limit rod 65, the contact rod 63 cannot deflect downwards and will exert pressure on the deceleration ring 515, thus reducing the speed at which the mounting housing 57 pops up and preventing it from hitting workers or damaging the lightning rod 54 due to excessive speed.

[0032] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the water removal mechanism 7 includes a water tank 71. Return springs 72 are provided on both sides of the interior of the water tank 71. Piston plates 73 are slidably connected to the interior of the water tank 71 via two sets of return springs 72. Two sets of inlet pipes 74 are connected through and fixedly to the top of the water tank 71, and two sets of outlet pipes 75 are connected through and fixedly to the bottom of the water tank 71. One-way valves are provided inside both the inlet pipes 74 and the outlet pipes 75. A toothed rod 76 is fixedly connected to the side of each set of piston plates 73 that is close to the other. The end of the inlet pipe 74 away from the water tank 71 is connected through and fixedly to the bottom of the mounting cylinder 51. The end of the outlet pipe 75 away from the water tank 71 is connected through and fixedly to the bottom of the rainproof top plate 4. The rotating assembly 8 includes a circular groove 81 and a rotating rod 83. The circular groove 81 is located at the bottom of the mounting housing 57, and an embedding groove 82 is provided on the inner wall of the circular groove 81. 83 is rotatably connected to the top of the water tank 71. A rotating gear 84 is fixedly connected to the bottom of the rotating rod 83. The teeth on the rack 76 are matched with the teeth on the rotating gear 84. The rotating gear 84 is an incomplete gear. When the rotating gear 84 rotates and its teeth mesh with the teeth on the rack 76, it will drive the rack 76 and the piston plate 73 to move. A round block 85 is fixedly connected to the top of the rotating rod 83. A groove 86 is opened on both sides of the round block 85. A compression spring 87 is set inside the groove 86. An arc-shaped block B88 is slidably connected inside the groove 86 through the compression spring 87. In the initial state, half of the arc-shaped block B88 is located in the embedding groove 82. The number of embedding grooves 82 is set to ten. The arc-shaped block B88 is stuck in the embedding groove 82 so that when the rotating housing 57 is rotated, it will drive the rotating rod 83 to rotate synchronously. The setting of ten sets of embedding grooves 82 can ensure that the arc-shaped block B88 is engaged at various angles.

[0033] In use, when the mounting housing 57 is inserted downwards into the mounting cylinder 51, the circular groove 81 moves downwards, causing the circular block 85 to enter the circular groove 81, while the arc-shaped block B88 enters the embedding groove 82. If the arc-shaped block B88 is misaligned with the embedding groove 82, its arc surface will be squeezed into the groove 86. Subsequently, when the mounting housing 57 rotates, it causes the embedding groove 82 to rotate and fit into the groove 86. The compression spring 87 then causes the arc-shaped block B88 to pop out and enter the embedding groove 82. The setting of ten sets of embedding grooves 82 can ensure the insertion of the arc-shaped block B88. If water is found to be accumulated at the bottom of the mounting cylinder 51, the lightning rod 54 can be used to rotate the mounting housing 57. The rotation of the mounting housing 57 will cause the circular block 85 to rotate synchronously through the cooperation of the embedding groove 82 and the arc-shaped block B88 stuck in it. The rotation of the rotating rod 83 causes the rotating gear 84 to rotate. When the rotating gear 84 rotates and its upper teeth mesh with the upper teeth of the gear rod 76, it causes the gear rod 76 and the piston plate 73 to move towards the side of the water tank 71. The return spring 72 is compressed. The movement of the piston plate 73 towards the side of the water tank 71 squeezes the water inside, causing it to be discharged through the water outlet pipe 75 to the top of the rainproof top plate 4. When the upper teeth of the rotating gear 84 disengage from the upper teeth of the gear rod 76, the return spring 72 rebounds, causing the piston plate 73 to move back to the center position of the water tank 71. At this time, a negative pressure is generated on the side of the water tank 71, which draws out the water accumulated at the bottom of the installation cylinder 51 through the water inlet pipe 74. This facilitates the treatment of water accumulated in the installation cylinder 51 and prevents the water from affecting the lightning protection of the transformer body 1.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
