Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal power generation, and in particular to a transformer winding protection mechanism. Background Technology
[0002] Transformer winding vibration is a common problem during transformer operation. The main hazards of transformer winding vibration include: Mechanical damage: Prolonged vibration can cause internal transformer parts to loosen, wear out, or even break, especially critical components such as windings and cores, which may affect the normal operation of the transformer.
[0003] Degradation of electrical performance: Vibration can cause wear and cracks in the insulation material inside the transformer, resulting in a decrease in insulation performance. In severe cases, it may lead to electrical faults such as short circuits and arcing.
[0004] Noise pollution: Transformer vibrations generate significant noise, causing noise pollution to the surrounding environment and affecting people's normal lives and work.
[0005] Energy waste: Vibration can lead to energy loss, reduce transformer efficiency, and increase energy waste.
[0006] Increased risk of failure: Vibration may also cause connecting parts (such as bolts, pins, etc.) to loosen, leading to short circuits or other electrical faults, increasing the risk of transformer failure.
[0007] Causes of transformer winding vibration: When current flows through the winding, it generates a magnetic field. This magnetic field interacts with the magnetic flux in the iron core, causing slight deformation of the iron core and the winding, which in turn produces vibration.
[0008] The magnetostriction of silicon steel sheets can also cause vibration in the iron core.
[0009] Uneven windings or too few primary coils can also cause vibration.
[0010] Transformer vibration direction: The vibrations generated by a transformer during operation can be in the up-down, left-right, and front-back directions, depending on its internal structure and operating conditions.
[0011] Therefore, timely monitoring and control of transformer vibration is crucial to ensure its safe and stable operation. Existing measures to prevent transformer vibration primarily involve using vibration-damping pads or feet on the installation foundation to reduce vibration and protect the transformer windings from damage. However, existing transformer vibration damping devices have the following problems: first, they can only reduce vibration in one direction and cannot provide all-around protection; second, they cannot protect against vibration across the entire frequency band. During transformer operation, changes in operating parameters and structure cause variations in the magnitude and direction of vibration, which existing damping devices cannot adjust to.

Each longitudinal seat has longitudinal baffles slidably connected to both sides. A spring is provided between the two sides of each longitudinal seat and the longitudinal baffles. A longitudinal adjustment device is provided on the outer side of the two longitudinal baffles of each longitudinal seat.

[0016] Each longitudinal seat guide rod of the longitudinal seat is fitted with a No. 1 spring, and each No. 1 spring abuts against the longitudinal seat and the longitudinal baffle on both sides.
[0017] The longitudinal moving device includes a longitudinal adjusting base plate, a longitudinal adjusting bolt threadedly connected to the middle of the longitudinal adjusting base plate, a base plate rotatably connected to the longitudinal adjusting bolt, and longitudinal adjusting plates fixedly connected to both sides of the same longitudinal seat.
[0018] The longitudinal adjustment plate guide rods on both sides of the longitudinal adjustment plate pass through the bottom of the base and are slidably connected to the base. The longitudinal adjustment plate guide rods are fixed on the longitudinal adjustment base plate.
[0019] The inclined surface of the longitudinal baffle on the side of the longitudinal baffle and the inclined surface of the longitudinal adjustment plate on the corresponding side of the longitudinal adjustment plate are slidably connected.
[0020] The longitudinal seat groove at the upper part of the longitudinal seat is slidably connected to the transverse seat slider at the lower part of the transverse seat.
[0021] The transverse seat guide rods on both sides of the transverse seat are slidably connected to the transverse baffle waist grooves on both sides of the transverse baffle.
[0022] A second spring is fitted onto the outside of each transverse seat guide rod of the transverse seat, and each second spring abuts against the transverse seat and the transverse baffle on both sides.
[0023] The lateral movement device includes a longitudinal adjustment base plate, a lateral adjustment bolt threadedly connected to the middle of the longitudinal adjustment base plate, a base plate rotatably connected to the lateral adjustment bolt, and lateral adjustment plates fixedly connected to both sides of the longitudinal adjustment base plate.
[0024] The guide rods on both sides of the lateral adjustment plate pass through the bottom of the base and are slidably connected to the base. The guide rods are fixed on the longitudinal adjustment base plate.
[0025] The inclined surface of the transverse baffle on the side of the transverse baffle and the inclined surface of the corresponding transverse adjustment plate on the side of the transverse adjustment plate are slidably connected.
[0026] The two vertical guide rods on the upper part of the horizontal seat are slidably connected to the two screw holes on the lower part of the base plate.

When the transformer vibrates abnormally vertically, rotating the vertical adjusting bolt changes the length and preload of the No. 3 spring, thus changing the frequency of its vibration, thereby suppressing the transformer's vertical vibration. When the transformer vibrates abnormally longitudinally in the front-back direction, rotating the longitudinal adjusting bolt changes the length and preload of the No. 1 spring, thus changing the frequency of its vibration, thereby suppressing the transformer's longitudinal vibration. When the transformer vibrates abnormally laterally in the left-right direction, rotating the transverse adjusting bolt changes the length and preload of the No. 2 spring, thus changing the frequency of its vibration, thereby suppressing the transformer's lateral vibration.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Referring to Figures 1 to 6, this device includes a base 110. A longitudinal seat 120 is provided on each of the front and rear sides of the base 110. Longitudinal bottom grooves 113 penetrating the base 110 are provided on the bottom of the left and right sides of the base 110. Two longitudinal seat sliders 122 are provided on the lower part of the left and right sides of the longitudinal seat 120, and the two longitudinal seat sliders 122 are slidably connected to the bottom grooves 113 on both sides. Symmetrical longitudinal seat guide rods 123 are provided on the left and right sides of the longitudinal seat 120. Two symmetrical longitudinal baffles 130 are provided on the front and rear sides of the longitudinal seat 120. Longitudinal guide plate holes 132 are provided on the left and right sides of the longitudinal baffles 130, and the longitudinal guide plate holes 132 are slidably connected to the corresponding longitudinal seat guide rods 123. Two first springs 180 are provided between each longitudinal seat 120 and each longitudinal baffle 130. Each first spring 180 is sleeved on the outside of the longitudinal seat guide rod 123, and each first spring 180 abuts against the longitudinal seat 120 on both sides. The longitudinal baffles 130 and the longitudinal seat 120 are provided with longitudinal adjustment devices on the outer sides of the two longitudinal baffles 130.
[0040] Referring to Figures 1 to 7, the longitudinal adjustment device includes a longitudinal adjustment base plate 230, two longitudinal adjustment plates 140 fixedly connected to the longitudinal adjustment base plate 230, and longitudinal adjustment bolts 240 connected to the longitudinal adjustment base plate 230. Each longitudinal seat 120 is equipped with a longitudinal adjustment device, and each longitudinal seat 120 has a longitudinal adjustment plate 140 on its front and rear sides. Each longitudinal adjustment plate 140 has two longitudinal adjustment plate guide rods 142 at its lower part. The two longitudinal adjustment plate guide rods 142 are slidably connected to the first guide hole 114 on the base 110 corresponding to the longitudinal adjustment plate guide rod 142. The longitudinal adjustment bolts 240 are threadedly connected to the middle of each longitudinal adjustment base plate 230. The longitudinal adjustment bolts 240 are rotatably connected to the base 110. The longitudinal adjustment plate inclined surface 141 on the side of each longitudinal adjustment plate 140 is slidably connected to the longitudinal baffle inclined surface 131 on the side of the corresponding longitudinal baffle 130. In normal state, the first spring 180 on both sides of each longitudinal seat 120 is... It suppresses transformer vibration. Rotating the longitudinal adjusting bolt 240 can drive the corresponding longitudinal adjusting base plate 230 to move up and down. The longitudinal adjusting base plate 230 drives the corresponding longitudinal adjusting plate 140 to move up and down. When the longitudinal adjusting plate 140 moves up and down, it drives the longitudinal baffle 130 connected to it to move synchronously through the first spring 180. Each longitudinal adjusting base plate 230 controls the longitudinal baffles 130 on both sides of the same longitudinal seat 120 to move synchronously. When the two longitudinal adjusting plates 140 move down, the two longitudinal baffles 130 move closer to the middle longitudinal seat 120, and the corresponding first spring 180 is compressed. When the two longitudinal adjusting plates 140 move up, the two longitudinal baffles 130 move away from the middle longitudinal seat 120, and the corresponding first spring 180 extends. When the length of the first spring 180 changes, the vibration frequency of the first spring 180 will change, thereby achieving the purpose of suppressing longitudinal vibration in the front and rear directions of the transformer.
[0041] Referring to Figures 1 to 4 and Figures 8 to 11, each longitudinal seat 120 has a longitudinal seat groove 121 on its upper part, and each transverse seat 150 has a transverse seat slider 151 on its lower part. The longitudinal seat groove 121 on the upper part of each longitudinal seat 120 and the transverse seat slider 151 on the lower part of the corresponding transverse seat 150 are slidably connected. Transverse baffles 160 are provided on the left and right sides of the two transverse seats 150 respectively. Two transverse seat guide rods 152 are provided on the left and right sides of each transverse seat 150 respectively. Long strip-shaped transverse baffle grooves 162 are provided on the front and rear sides of each transverse baffle 160. The transverse seat guide rods 152 on the same side of the two transverse seats 150 are slidably connected to the corresponding transverse baffle grooves 162. A second spring 190 is provided between the transverse seat 150 and the transverse baffles 160 on both sides. A second spring 190 is fitted on the outside of each transverse seat guide rod 152. The two sides of each second spring 190 abut against the transverse seat 150. And a transverse baffle 160, each transverse baffle 160 is provided with a transverse adjustment device on the outside.
[0042] Referring to Figures 1 to 4 and 8 to 11, the lateral adjustment device includes a lateral adjustment base plate 250, two lateral adjustment plates 170 fixedly connected to the lateral adjustment base plate 250, and lateral adjustment bolts 260 connected to the lateral adjustment base plate 250. Each lateral baffle 160 has a lateral adjustment plate 170 on its outer side. Each lateral adjustment plate 170 has two lateral adjustment plate guide rods 172 at its lower part, and the two lateral adjustment plate guide rods 172 are fixedly connected to the lateral adjustment base plate 250. The two lateral adjustment plate guide rods 172 are slidably connected to the second guide hole 116 on the base 110 corresponding to the lateral adjustment plate guide rod 172. Each lateral adjustment base plate 250 is threadedly connected to the lateral adjustment bolt 260 in the middle. The lateral adjustment bolt 260 is rotatably connected to the base 110. The lateral baffle slope 161 on the side of each lateral baffle 160 and the corresponding lateral adjustment plate slope 171 on the side of the lateral adjustment plate 170 are also connected. In a sliding connection, under normal conditions, the second springs 190 on both sides of each transverse seat 150 suppress transformer vibration. Rotating the transverse adjusting bolt 260 moves the transverse adjusting base plate 250 up and down. The longitudinal adjusting base plate 250 moves the transverse adjusting plate 170 up and down. When the transverse adjusting plate 170 moves up and down, it drives the transverse baffle 160 connected to it to move synchronously through the second spring 190. When the two transverse adjusting plates 170 move down, the two transverse baffles 160 move closer to the middle transverse seat 150, and the corresponding second springs 190 are compressed. When the two transverse adjusting plates 170 move up, the two transverse baffles 160 move away from the middle transverse seat 150, and the corresponding second springs 190 extend. When the length of the second spring 190 changes, the frequency of the second spring 190's vibration changes, thereby achieving the purpose of suppressing the transverse vibration of the transformer in the left and right directions.
[0043] Referring to Figures 1 to 4 and 8 to 11, the upper left and right sides of the horizontal seat 150 are respectively provided with horizontal seat vertical guide rods 153. Each horizontal seat 150 has a base plate 210 on its upper part. The base plate 210 has base plate sliding sleeves 211 on both sides. The base plate sliding sleeves 211 on both sides of the base plate 210 are slidably connected to the horizontal seat vertical guide rods 153 on both sides of the horizontal seat 150. The horizontal seat 150 has a horizontal seat hole 154 in the middle. The base plate 210 has a base plate screw hole 212 in the middle. The vertical adjusting bolt 270 is rotatably connected in the horizontal seat hole 154. The vertical adjusting bolt 270 is threaded to the base plate screw hole 212 in the middle of the base plate 210. A No. 3 spring 220 is provided between the base plate 210 and the No. 3 spring 220. A No. 3 spring 220 is respectively fitted on the outside of each horizontal seat vertical guide rod 153. The No. 3 spring 220 abuts against the base plate 210 on both sides. In normal operation, the No. 3 spring 220 on the upper part of each horizontal seat 150 suppresses the vibration of the transformer. Rotating the vertical adjusting bolt 270 causes the base plate 210 to move up and down. When the base plate 210 moves down, the No. 3 spring 220 is compressed. When the base plate 210 rises, the No. 3 spring 220 extends. When the length of the No. 3 spring 220 changes, the frequency of its vibration changes, thereby achieving the purpose of suppressing the vertical vibration of the transformer.
[0044] When using this device, the lower part of the transformer 310 is fixed to the upper part of two base plates 210 respectively. When the transformer vibrates abnormally vertically, rotating the vertical adjusting bolt 270 causes the base plate 210 to move vertically, changing the length and preload of the third spring 220. This changes the vibration frequency of the third spring 220, thereby suppressing the vertical vibration of the transformer. When the transformer vibrates abnormally longitudinally in the front-back direction, rotating the longitudinal adjusting bolt 240 causes the corresponding longitudinal adjusting base plate 230 to move vertically. The longitudinal adjusting base plate 230 then causes the corresponding longitudinal adjusting plate 140 to move vertically. When the longitudinal adjusting plate 140 moves vertically, it causes the connected longitudinal baffle 130 to move synchronously. This changes the length and preload of the first spring 180, changing the vibration frequency of the first spring 180, thereby suppressing the longitudinal vibration of the transformer in the front-back direction. When the transformer vibrates abnormally laterally in the left-right direction, rotating the lateral adjusting bolt 260 causes the longitudinal adjusting base plate 250 to move vertically. The vertical movement of the bottom plate 250 and the horizontal adjustment plate 170 cause the horizontal adjustment plate 170 to move vertically. When the horizontal adjustment plate 170 moves vertically, it causes the horizontal baffle 160 connected to it to move synchronously. When the length and preload of the second spring 190 change, the frequency of the second spring 190 will change, thereby achieving the purpose of suppressing the horizontal vibration of the transformer in the left and right directions.
[0045] Under normal conditions, the No. 1 spring 180 on both sides of each longitudinal seat 120 suppresses transformer vibration, the No. 2 spring 190 on both sides of each transverse seat 150 suppresses transformer vibration, and the No. 3 spring 220 on the upper part of each transverse seat 150 suppresses transformer vibration. When the transformer vibrates abnormally vertically, rotating the vertical adjusting bolt 270 changes the length and preload of the No. 3 spring 220, thus changing the vibration frequency of the No. 3 spring 220, thereby suppressing the vertical vibration of the transformer. When the transformer vibrates abnormally longitudinally in the front-back direction, rotating the longitudinal adjusting bolt 240 changes the length and preload of the No. 1 spring 180, thus changing the vibration frequency of the No. 1 spring 180, thereby suppressing the longitudinal vibration of the transformer in the front-back direction. When the transformer vibrates abnormally laterally in the left-right direction, rotating the transverse adjusting bolt 260 changes the length and preload of the No. 2 spring 190, thus changing the vibration frequency of the No. 2 spring 190, thereby suppressing the lateral vibration of the transformer in the left-right direction.
