Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of voltage transformers, and in particular relates to a capacitive voltage transformer. Background Art
[0002] Capacitor voltage transformer is a voltage transformer that divides the voltage by series capacitors, and then reduces the voltage and isolates it through electromagnetic transformers. It is used as a voltage transformer for meters, relay protection, etc. Capacitor voltage transformer can also couple the carrier frequency to the transmission line for long-distance communication, remote measurement, selective line high-frequency protection, remote control, teletypewriting, etc.
[0003] However, the existing capacitive voltage transformer has weak wind resistance, which leads to the risk of breakage in windy weather. Utility Model Content
[0004] The purpose of the present invention is to provide a capacitive voltage transformer in response to the above-mentioned technical problems, which has a strong wind resistance, thereby avoiding the risk of the capacitive voltage transformer being easily broken in windy weather.
[0005] In view of this, the utility model provides a capacitive voltage transformer, comprising: an oil tank and a transformer body, the transformer body being arranged on the upper surface of the oil tank, and being characterized in that a connecting plate is provided at the top of the oil tank through bolts and at the top of the transformer body through bolt fixing sleeves, the two connecting plates being symmetrically arranged up and down, connecting plates being installed on both sides of the two connecting plates, and the connecting plates being provided with three sets of buffering reinforcement devices from top to bottom, and the buffering reinforcement devices being used to buffer and reinforce the surface of the transformer body.
[0006] In this technical solution, two connecting plates are fixed to the lower surface of the top of the transformer body and the upper surface of the oil tank by bolts respectively, and the connection between the transformer body and the oil tank is improved by the connecting plate, thereby improving the wind resistance of the transformer body. The wind will produce a certain impact force on the transformer body. At this time, the buffer reinforcement device will play a role in buffering and shock absorption, absorbing part of the impact force, thereby protecting the transformer body from shaking.
[0007] In the above technical solution, further, the connecting plate and the connecting disk are both provided with a threaded hole, and the threaded hole is threadedly connected with a locking bolt.
[0008] In this technical solution, the connecting plate and the connecting disc are tightly connected together by locking bolts to form a stable overall structure, so that the transformer body on the upper surface of the oil tank is buffered and reinforced by the buffer reinforcement device on the connecting plate.
[0009] In the above technical solution, further, the buffer reinforcement device includes: a threaded rod, which is threadedly connected to the connecting plate, and both ends are arranged through the connecting plate, one end of the threaded rod is connected to a knob, and the other end is rotatably connected to a first arc-shaped clamping plate, and a buffer component is provided on the inner side of the first arc-shaped clamping plate, and the buffer component is tightly attached to the transformer body.
[0010] In this technical solution, after the connecting plate is installed on the connecting disk, the operator rotates the knob to drive the threaded rod inward. Because the threaded rod is rotationally connected to the first curved clamping plate, it does not drive the first curved clamping plate to rotate, allowing the first curved clamping plate to move closer to the transformer body. After adjustment, the first curved clamping plate is tightly attached to the transformer body through the buffer assembly on its inner side. The elastic material of the buffer assembly can absorb the impact and vibration caused by wind, protecting the transformer body from damage.
[0011] In the above technical solution, further, the buffer component includes:
[0012] Slide grooves are provided at both ends of the inner side surface of the first arc-shaped clamping plate, wherein a slider is slidably connected in the slide groove, a side of the slider away from the slide groove is hingedly connected to a hinge plate, and the other end of the hinge plate is hingedly connected to the second arc-shaped clamping plate;
[0013] A buffer spring, one end of which is connected to the inner wall of the sliding groove, and the other end of which is connected to the sliding block.
[0014] In this technical solution, when wind force acts on the capacitive voltage transformer, the transformer body will be subjected to certain impacts and vibrations. At this time, the buffer spring will absorb part of the impact and vibration energy and convert it into deformation energy of the spring. As the spring deforms, the slider will slide in the slide groove and drive the hinge plate and the second arc-shaped clamping plate to move together. Since the design of the hinge plate and the second arc-shaped clamping plate has a certain flexibility and adaptability, they can fit tightly on the surface of the transformer body, playing a clamping and buffering role. When the wind force decreases or disappears, the buffer spring will return to its original state and push the slider, hinge plate and second arc-shaped clamping plate back to their original position, thereby continuing to provide stable support and buffering for the transformer body.
[0015] In the above technical solution, further, the inner side surface of the second arc-shaped clamping plate is fixedly connected with a rubber pad.
[0016] In this technical solution, the rubber pad, as a highly elastic material, has good shock absorption and buffering properties, and its softness and elasticity can prevent the second arc-shaped clamping plate from causing scratches or wear on the transformer body during the clamping process.
[0017] In the above technical solution, further, a mounting plate is provided at the bottom of the oil tank, and a mounting hole is provided on the mounting plate.
[0018] In this technical solution, the staff only needs to use bolts to penetrate the mounting holes to install the transformer body and the oil tank on the transmission line.
[0019] The beneficial effects of the present utility model are as follows: the two connecting plates are fixed to the lower surface of the top of the transformer body and the upper surface of the oil tank by bolts respectively, and the connection between the transformer body and the oil tank is improved by the connecting plate, thereby improving the wind resistance of the transformer body, and the wind will produce a certain impact force on the transformer body. At this time, the buffer reinforcement device will play a role of buffering and shock absorption, absorbing part of the impact force, thereby protecting the transformer body from shaking.

[0030] Example 1:
[0031] Depend on Figure 1-3 As shown, this embodiment provides a capacitive voltage transformer, comprising: an oil tank 1 and a transformer body 2, wherein the transformer body 2 is arranged on the upper surface of the oil tank 1, and is characterized in that a connecting plate 3 is fixed to the top of the oil tank 1 and the top of the transformer body 2 by bolts, and the two connecting plates 3 are symmetrically arranged up and down, and connecting plates 4 are installed on both sides of the two connecting plates 3. The connecting plates 4 are provided with three groups of buffer reinforcement devices 6 from top to bottom, and the buffer reinforcement devices 6 are used to buffer and reinforce the surface of the transformer body 2. The two connecting plates 3 are fixed to the lower surface of the top of the transformer body 2 and the upper surface of the oil tank 1 respectively by bolts, and the connecting plates 4 are used to improve the connection between the transformer body 2 and the oil tank 1, thereby improving the wind resistance of the transformer body 2. The wind will generate a certain impact force on the transformer body 2. At this time, the buffer reinforcement device 6 will play a role in buffering and shock absorption, absorbing part of the impact force, thereby protecting the transformer body 2 from shaking.
[0032] Furthermore, the connecting plate 4 and the connecting disc 3 are both provided with a threaded hole 7, which is threadedly connected to a locking bolt 5. The locking bolt 5 tightly connects the connecting plate 4 and the connecting disc 3 together to form a stable overall structure, thereby providing a buffer reinforcement device 6 on the connecting plate 4 to cushion and reinforce the transformer body 2 on the upper surface of the oil tank 1.
[0033] Furthermore, the buffer reinforcement device 6 includes: a threaded rod 601, which is threadedly connected to the connecting plate 4 and is provided at both ends through the connecting plate 4. One end of the threaded rod 601 is connected to a knob 602, and the other end is rotatably connected to a first arc-shaped clamping plate 603. The inner side of the first arc-shaped clamping plate 603 is provided with a buffer component 604, and the buffer component 604 is tightly attached to the transformer body 2. After the connecting plate 4 is installed on the connecting disk 3, the staff rotates the knob 602 to drive the threaded rod 601 to rotate inward. Since the threaded rod 601 is rotatably connected to the first arc-shaped clamping plate 603, it will not drive the first arc-shaped clamping plate 603 to rotate, so that the first arc-shaped clamping plate 603 approaches the transformer body 2. After being adjusted into place, the first arc-shaped clamping plate 603 is tightly attached to the transformer body 2 through the buffer component 604 on its inner side. The elastic material of the buffer component 604 can absorb the impact and vibration generated by wind force, thereby protecting the transformer body 2 from damage.
[0034] Furthermore, the buffer assembly 604 includes: a chute 605 disposed at both ends of the inner side of the first curved clamping plate 603, a slider 606 slidably connected within the chute 605, a hinged plate 607 hinged on the side of the slider 606 facing away from the chute 605, and a second curved clamping plate 608 hinged on the other end of the hinged plate 607; and a buffer spring 609, one end of which is connected to the inner sidewall of the chute 605 and the other end to the slider 606. When wind forces act on the capacitor voltage transformer, the transformer body 2 is subjected to certain impacts and vibrations. The buffer spring 609 absorbs some of the impact and vibration energy and converts it into deformation energy. As the spring deforms, the slider 606 slides within the chute 605, driving the hinge plate 607 and the second curved clamping plate 608 to move together. Because the hinge plate 607 and the second curved clamping plate 608 are designed to be flexible and adaptable, they fit snugly against the surface of the transformer body 2, providing both clamping and cushioning. When the wind decreases or disappears, the buffer spring 609 returns to its original position, pushing the slider 606, hinge plate 607, and second curved clamping plate 608 back to their original positions, thereby providing continued stable support and cushioning for the transformer body 2.
[0035] Furthermore, a rubber pad 8 is fixedly connected to the inner side of the second arc-shaped clamping plate 608. The rubber pad 8 is a highly elastic material with good shock absorption and cushioning properties. Its softness and elasticity can prevent the second arc-shaped clamping plate 608 from scratching or wearing the transformer body 2 during the clamping process.
[0036] Furthermore, a mounting plate 9 is provided at the bottom of the oil tank 1, and a mounting hole 10 is provided on the mounting plate 9. The staff only needs to use bolts to penetrate the mounting holes 10 to install the transformer body 2 and the oil tank 1 on the transmission line.
[0037] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
