Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer with a lead-out device. Background Art

[0002] Transformer generally refers to power transformer, which is a static electrical equipment, used to convert a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency. It is a static device with two or more windings. In order to transmit electrical energy, it converts the AC 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 current and voltage are different. Transformers are mainly installed in the open air, the wild or in areas with frequent lightning. In the case of bad weather, they are easily struck by lightning.

[0003] The patent document with publication number CN219591216U discloses a transformer with a lead-out device, including a transformer body, a rainproof top plate on the top of the transformer body, and a lightning rod on the top of the rainproof top plate, four corners of the top of the transformer body are fixedly installed with support legs, and the top of the support legs is fixedly connected to the rainproof top plate, and a conductive sleeve is fixedly installed on the inner side of the top of the rainproof top plate. In the above application document, a conductive plug is inserted into the conductive sleeve through a clamping hole along the top of the rainproof top plate, and a locking column is clamped into the locking slide groove. When the locking column is clamped into the bottom of the locking slide groove, the lightning rod is rotated to drive the conductive plug and the locking column to rotate, and the locking column is clamped into the clamping part. The locking column is locked by the clamping part, and the conductive plug is applied with elastic force by the compression spring, so that the lightning rod is fixedly installed on the top of the rainproof top plate. It is more troublesome to install the lightning rod, and the locking column needs to be aligned with the locking slide groove for insertion, which is more time-consuming and labor-intensive, and is not conducive to installation and subsequent maintenance work.

[0006] According to the above technical solution, there are four groups of support legs, and the material of the four groups of support legs are all nylon.

[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.

[0014] According to the above technical solution, the teeth on the gear rod are matched with the teeth on the rotating gear, and the rotating gear is an incomplete gear. When the rotating gear rotates and its upper teeth are meshed with the teeth on the gear rod, the gear rod and the piston plate will be driven to move.

[0015] The present invention provides a transformer with a lead-out device. It has the following beneficial effects:

[0016] (1) The present invention provides a lead-out device installation mechanism so that the lightning rod, threaded column, installation shell, installation tube, lead-out ground wire and other components can be used to firmly install the lightning rod on the top of the rainproof roof, thereby realizing lightning protection for the transformer body. When the lightning rod needs to be inspected, the piston rods A on both sides can be pulled upward to make the installation shell pop up. At this time, the installation shell and the lightning rod can be removed, which is convenient for subsequent inspection and maintenance work.

[0017] (2) The present invention provides a deceleration mechanism so that when the piston rods A on both sides are pulled upward and the spring rebounds to drive the installation housing to move upward, the speed of the installation housing bouncing upward is slowed down by the cooperation of the rotating shaft, contact rod, elastic rope, deceleration ring and other components to prevent the installation housing from bouncing upward too fast and injuring the staff or causing damage to the lightning rod. When the installation housing is inserted downward into the installation tube, it will not generate too much resistance to affect the installation of the lightning rod.

[0018] (3) The present invention sets a water removal mechanism so that when water is found at the bottom of the installation tube, the rotating lightning rod drives the installation shell to rotate. The rotation of the installation shell drives the rotating rod to rotate synchronously through the cooperation between the arc block B and the embedded groove. The rotation of the rotating rod drives the rotating gear to rotate. The rotation of the rotating gear drives the piston plate to move repeatedly, so that negative pressure is repeatedly formed on both sides of the water tank, thereby sucking away the accumulated water in the installation tube through the water inlet pipe and discharging it to the rainproof top plate through the water outlet pipe, which facilitates the treatment of the accumulated water in the installation tube and prevents the accumulated water from affecting the lightning protection of the transformer body.

The mounting tube 51 penetrates and is fixedly connected to the top of the rainproof top plate 4. The side of the mounting tube 51 is provided with a lead-out ground wire 52. The top of the mounting tube 51 is provided with a sealing ring 53. The surface of the lightning rod 54 is provided with a pressure ring 55. The bottom of the lightning rod 54 is fixedly connected with a threaded column 56. The threaded column 56 is connected to the internal thread of the mounting shell 57. The surface of the mounting shell 57 is provided with an annular groove 58. The inner wall of the mounting tube 51 is provided with a groove 59. The interior of the groove 59 is provided with a telescopic spring 510. The interior of the groove 59 is slidably connected through the telescopic spring 510. There is an arc block A511, the arc surface of the arc block A511 is upward, and the lateral length of the groove 59 is greater than the lateral length of the arc block A511. When the arc surface of the arc block A511 is squeezed, it will move into the groove 59, and the arc block A511 can be completely retracted into the groove 59. The side of the mounting tube 51 is penetrated and fixedly connected with a gas pressure chamber 512. The end of the gas pressure chamber 512 away from the mounting tube 51 is penetrated and fixedly connected to the bottom of the rainproof top plate 4. The internal piston of one end of the gas pressure chamber 512 is slidably connected to a piston rod A513, and the internal piston of the other end of the gas pressure chamber 512 is slidably connected to a piston rod B514. The piston rod B514 is away from the end of the gas pressure chamber 512. The end is fixedly connected to the arc block A511, a speed reducing ring 515 is fixedly connected to the inner wall of the mounting tube 51, a pop-up spring 516 is arranged at the inner bottom of the mounting tube 51, the longitudinal width of the groove 59 is equal to the longitudinal width of the annular groove 58, and one-half of the arc block A511 is located inside the annular groove 58 in the initial state, the pop-up spring 516 is in a compressed state in the initial state, the arc block A511 is stuck in the annular groove 58 so that the mounting shell 57 cannot be separated from the mounting tube 51, a speed reducing mechanism 6 and a rotating assembly 8 are arranged at the bottom of the mounting shell 57, a water removing mechanism 7 is arranged inside the mounting tube 51, and the speed reducing 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. The side of the connecting plate 61 is rotatably connected to the rotating shaft 62. The side of the rotating shaft 62 is fixedly connected to the contact rod 63. The top of the contact rod 63 is fixedly connected to the elastic rope 64. The end of the elastic rope 64 away from the contact rod 63 is fixedly connected to the connecting plate 61. The side of the connecting plate 61 is fixedly connected to the limit rod 65. 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 with the deceleration ring 515, resistance will be generated. ;

[0031] When in use, when encountering bad weather, the support leg 3 isolates the lightning rod 54 and the transformer body 1 into two parts to prevent the transformer body 1 from conducting electricity with the lightning rod 54. The lightning rod 54 will transfer electricity to the installation shell 57 through the threaded column 56, and the installation shell 57 will transfer electricity to the installation cylinder 51, and finally to the ground through the lead-out ground wire 52, so as to achieve the effect of lightning protection. When the lightning rod 54 needs to be disassembled and repaired, the piston rods A513 on both sides are pulled upwards. At this time, the air pressure in the air pressure chamber 512 will drive the piston rod B514 to move, so that the arc block A511 leaves the annular groove 58 and shrinks into the groove 59. When the telescopic spring 510 is compressed and the arc block A511 leaves the annular groove 58 and loses the restriction on the installation shell 57, the pop-up spring 516 will rebound and drive the installation shell 57 to bounce upward, and the groove 59 is misaligned with the annular groove 58. At this time, the piston rod A513 is released, and the telescopic spring 510 will rebound and drive the arc block A511 to pop out, and the piston rod A513 and the piston rod B514 will move and restore accordingly. Finally, the installation shell 57 and the lightning rod 54 are taken out, and the lightning rod 54 can be rotated to separate the bottom threaded column 56 from the installation shell 57. When reinstalling, the bottom threaded column 56 of the lightning rod 54 is rotated to The installation shell 57 is inserted into the installation tube 51 downward, and the pop-up spring 516 is gradually squeezed. At first, the arc surface of the arc block A511 is squeezed by the bottom of the installation shell 57 and shrinks into the groove 59, and the telescopic spring 510 is tightened. When the groove 59 fits with the annular groove 58, the telescopic spring 510 rebounds and drives the arc block A511 to snap into the annular groove 58. At this time, the installation shell 57 can no longer leave the installation tube 51 to complete the installation of the lightning rod 54. When the installation shell 57 is inserted downward into the installation tube 51, the connecting plate 61 moves downward and drives the contact rod 63 downward. The contact rod 63 moves and contacts with the deceleration ring 515. At this time, the contact rod 63 will deflect upward and will not be squeezed too much with the deceleration ring 515 to generate resistance. Then the elastic rope 64 drives the contact rod 63 to restore. When the pop-up spring 516 rebounds and drives the installation shell 57 to bounce upward, the connecting plate 61 moves upward and drives the contact rod 63 to move upward and contact the deceleration ring 515 again. At this time, due to the existence of the limit rod 65, the contact rod 63 cannot deflect downward and will be squeezed with the deceleration ring 515 to generate resistance, slowing down the speed of the installation shell 57 when it bounces upward, to prevent the bouncing speed from being too fast and injuring the staff or causing damage to the lightning rod 54.

[0032] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, the water removal mechanism 7 includes a water tank 71, and return springs 72 are arranged on both sides of the interior of the water tank 71. The two sides of the interior of the water tank 71 are respectively connected to piston plates 73 by two sets of return springs 72. The top of the water tank 71 is penetrated and fixedly connected with two sets of water inlet pipes 74, and the bottom of the water tank 71 is penetrated and fixedly connected with two sets of water outlet pipes 75. The inlet pipes 74 and the outlet pipes 75 are both provided with one-way valves. The sides of the two sets of piston plates 73 are fixedly connected with gear rods 76. The end of the water inlet pipe 74 away from the water tank 71 is penetrated and fixedly connected with the inner bottom of the mounting tube 51, and the end of the water outlet pipe 75 away from the water tank 71 is penetrated and fixedly connected with the bottom of the rainproof top plate 4. The rotating component 8 includes a circular groove 81 and a rotating rod 83. The circular groove 81 is opened at the bottom of the mounting shell 57, and an embedded groove 82 is opened on the inner wall of the circular groove 81. The rotating rod The top of the rotating rod 83 is fixedly connected with a rotating gear 84. The teeth on the gear rod 76 match the teeth on the rotating gear 84. The rotating gear 84 is an incomplete gear. When the rotating gear 84 rotates and its teeth are meshed with the teeth on the gear rod 76, the gear rod 76 and the piston plate 73 are driven to move. A round block 85 is fixedly connected to the top of the rotating rod 83. A groove body 86 is provided on both sides of the round block 85. A compression spring 87 is provided inside the groove body 86. An arc block B88 is slidably connected to the inside of the groove body 86 through the compression spring 87. In the initial state, one-half of the arc block B88 is located in the embedded groove 82, and the number of the embedded grooves 82 is set to ten groups. The arc block B88 is stuck in the embedded groove 82 so that when the rotating mounting shell 57 is rotated, the rotating rod 83 is driven to rotate synchronously. The setting of ten groups of embedded grooves 82 can ensure that the arc block B88 is stuck at various angles.

[0033] When in use, when the mounting shell 57 is inserted downward into the mounting tube 51, the circular groove 81 will move downward so that the round block 85 enters the circular groove 81, and the arc block B88 will enter the embedded groove 82. If the arc block B88 is not aligned with the embedded groove 82, its arc surface will be squeezed and compressed into the groove body 86. Then, when the mounting shell 57 rotates to drive the embedded groove 82 to rotate and fit into the groove body 86, the compression spring 87 drives the arc block B88 to pop out and enter the embedded groove 82. The setting of ten groups of embedded grooves 82 can ensure the insertion of the arc block B88. At this time, if water is found at the bottom of the mounting tube 51, the mounting shell 57 can be driven to rotate through the lightning rod 54. The rotation of the mounting shell 57 will drive the round block 85 to rotate synchronously through the cooperation of the embedded groove 82 and the arc block B88 stuck therein. The rotation of the rotating rod 83 drives the rotating rod 83 to rotate, and the rotation of the rotating rod 83 drives the rotating gear 84 to rotate. When the rotating gear 84 rotates and the teeth on the rotating gear 84 are meshed with the teeth on the toothed rod 76, the toothed rod 76 and the piston plate 73 are driven to move toward the side of the water tank 71. The return spring 72 is compressed, and the piston plate 73 moves toward the side of the water tank 71 to squeeze the water therein so that it is discharged to the top of the rainproof top plate 4 through the water outlet pipe 75. When the teeth on the rotating gear 84 are out of mesh with the teeth on the toothed rod 76, the return spring 72 rebounds and drives the piston plate 73 to move toward the center of the water tank 71 to restore. At this time, negative pressure is generated on the side of the water tank 71, so that the accumulated water at the bottom of the installation tube 51 is sucked through the water inlet pipe 74, which facilitates the treatment of the accumulated water in the installation tube 51 and prevents the accumulated water from affecting the lightning protection of the transformer body 1.
