Description

A suspended switch oil conservator for a large transformer Technical Field

[0001] This invention relates to the field of oil storage tank technology, specifically to a suspended switch oil storage tank for a large transformer. Background Technology

[0002] Large transformers commonly use suspended switch oil conservator, which is suspended above the transformer body by a bracket and uses insulating oil to regulate the oil level in the tank. The traditional structure is susceptible to mechanical vibration and temperature deformation during long-term operation, which leads to stress concentration at the sealing interface, fatigue of connecting parts, or increased risk of leakage, affecting the sealing stability of the oil conservator and the long-term reliable operation of the equipment.

[0003] Patent CN218663454U discloses a transformer oil conservator base fixing structure and a transformer oil conservator. The base fixing structure includes bases fixed to the wall of the oil conservator body via mounting components. The mounting components include a reinforcing plate, the inner side of which is welded and fixed to the wall of the oil conservator body. An angle plate is provided on the outer side of the reinforcing plate, comprising a transverse mounting portion and a longitudinal mounting portion. The transverse mounting portion is fixed to the outer side of the reinforcing plate. The base includes a support plate and angle steel fixed to the bottom of the support plate; the upper end face of the support plate abuts against the outer side of the reinforcing plate. The longitudinal mounting section is fixed to the support plate by bolts. The cabinet feet are fixed to the corner plates connected to the reinforcing plates by bolts. The reinforcing plates are welded to the cabinet wall. The welding will not penetrate the cabinet wall, making the operation safe and reliable. Moreover, the cabinet feet are composed of support plates and angle steel, which have high mechanical strength and are convenient for long-distance transportation. Although this patent solves the above problems, the installation is still not simple enough.

[0015] 2. In the suspended switch oil conservator of this large transformer, when the oil tank is affected by the operation of the transformer and transmits vibration, the support plate is affected by the torsion spring and thus generates a reaction force with the oil tank, thereby absorbing the vibration transmitted by the oil tank, achieving the effect of reducing the radial vibration of the oil tank, making the oil tank more stable during the operation of the transformer, and improving the safety of the device.

[0016] 3. In the suspended switch oil conservator of this large transformer, the bottom end of the disc-shaped vibration-absorbing spring is restricted by the fixed plate and thus contracts, so that the vibration transmitted vertically upward by the oil conservator can be more effectively transmitted to the disc-shaped vibration-absorbing spring. The disc-shaped vibration-absorbing spring can absorb the vibration transmitted vertically upward by the oil conservator, further improving the stability of the oil conservator and ensuring the safe operation of the device.

[0017] 4. In the suspended switch oil conservator of this large transformer, the end of the connecting pipe away from the oil tank is clamped on the bracket, which quickly aligns the connecting pipe with the transformer and maintains relative movement with the transformer, avoiding damage to the connecting pipe caused by swinging, and improving the safety of insulating oil transportation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-7. One embodiment of the present invention is: a suspended switch oil conservator for a large transformer, comprising an oil tank 1, a transformer 2 disposed on the front side of the oil tank 1, a cantilever 3 fixedly connected to the rear side of the transformer 2 for suspending and supporting the oil tank 1, a connecting pipe 4 fixedly connected to the lower front surface of the oil tank 1, an oil level gauge 5 fixedly connected to the left end of the oil tank 1, a pressure gauge 6 fixedly connected to the upper surface of the oil tank 1, a temperature gauge 7 fixedly connected to the upper surface of the oil tank 1, and a vibration damping device 8 disposed below the oil tank 1 for absorbing and damping the oil. The oil conservator 1 transmits vibrations during the operation of transformer 2. An anti-sway device 9 is installed above transformer 2 to prevent the connecting pipe 4 from swaying due to vibration and causing damage. The cantilever 3 keeps the oil conservator 1 away from transformer 2, facilitating individual handling of the oil conservator 1 and also facilitating maintenance of transformer 2. Lifting the oil conservator 1 upwards causes the conical locking block 10 to be pulled out of the grooved seat 11, thus quickly separating the oil conservator 1 from the cantilever 3, improving the ease of use of the device. The oil conservator 1 includes the conical locking block 10, which is fixedly connected to the oil conservator 1. On the lower surface, the grooved bracket 11 is fixedly connected to the top of the cantilever 3, and the pressure column 12 is fixedly connected to the lower surface of the oil conservator 1. The oil conservator 1 also includes a slot 13, which is opened on the front and rear sides of the conical block 10. The inner surface of the slot 13 is engaged with a locking rod 14. A pull plate 15 is fixedly connected to the end of the locking rod 14 away from the conical block 10. An elastic push rod 16 is fixedly connected to the inner surface of the top of the cantilever 3. The grooved bracket 11 has through holes on the front and rear sides, and the inner surface of the through holes is slidably connected to the locking rod 14. An elastic push rod 16 is provided between the pull plate 15 and the front and rear sides of the grooved bracket 11. The top free end of the spring-loaded elastic push rod 16 slides through the bottom surface of the grooved seat 11 and penetrates into the bottom surface of the inner wall of the grooved seat 11. The top free end of the elastic push rod 16 abuts against the bottom end of the conical block 10. The locking rod 14 is inserted into the slot 13 opened on the conical block 10, thereby locking the conical block 10 and the oil pillow 1 on the cantilever 3 and the grooved seat 11, improving the ease of installation of the device. The elastic push rod 16 pushes the conical block 10 upward through elastic force, thereby quickly pushing the conical block 10 out of the grooved seat 11, preventing the device from jamming and making it easier for the operator to operate.

[0023] Working principle: Insulating oil is stored in oil conservator 1, which is then installed on cantilever 3. Cantilever 3 keeps oil conservator 1 away from transformer 2, facilitating individual handling of oil conservator 1 and maintenance of transformer 2. Insulating oil can be introduced into transformer 2 through connecting pipe 4. During oil supply, oil level gauge 5 detects the oil level in oil conservator 1, allowing for monitoring of the amount of insulating oil stored. Simultaneously, pressure gauge 6 and temperature gauge 7 detect the temperature and pressure inside oil conservator 1, ensuring safety during operation. When oil conservator 1 needs replacement or maintenance, pull plate 15 is pulled away from the grooved seat 11. Pull plate 15 causes locking rod 14 to slide out of the slot 13 and conical locking block 10. When conical locking block 10 is no longer limited by locking rod 14, oil conservator 1 is lifted upwards. Oil pillow 1 drives the conical locking block 10 to be pulled out of the grooved seat 11, thereby quickly separating oil pillow 1 and cantilever 3, improving the ease of use of the device. Conversely, when oil pillow 1 is inserted into the grooved seat 11 through the conical locking block 10, and then the pull plate 15 is released, the elastic restoring action of the spring pulls the pull plate 15 closer to the grooved seat 11. The pull plate 15 then drives the locking rod 14 to be inserted into the slot 13 opened on the conical locking block 10, thereby locking the conical locking block 10 and oil pillow 1 on the cantilever 3 and the grooved seat 11, improving the ease of installation of the device. In addition, during the process of disassembling oil pillow 1, after the locking rod 14 is pulled out of the slot 13, the elastic push rod 16 pushes the conical locking block 10 upward through the elastic force, thereby quickly pushing the conical locking block 10 out of the grooved seat 11, preventing the device from jamming and making the operation of the operator easier.

[0024] Please refer to Figures 1-7. In another embodiment of the present invention, based on the above embodiments, the vibration damping device 8 includes a side abutment rod 81, which is hinged to the side surface of the grooved seat 11. A connecting rod 82 is fixedly connected to the top side surface of the side abutment rod 81. A rotating shaft 83 is hinged to the circumferential surface of the connecting rod 82. A support plate 84 is fixedly connected to the side of the rotating shaft 83 near the oil conservator 1. The oil conservator 1 is used to reduce the radial vibration generated by the oil conservator 1. When the oil conservator 1 is affected by the operation of the transformer 2 and transmits vibration, the support plate 84 is affected by the torsion spring and thus interacts with the oil conservator 1. The reaction force generates a reaction force, thereby absorbing the vibration transmitted by the oil conservator 1, achieving the effect of reducing the radial vibration of the oil conservator 1, making the oil conservator 1 more stable during the operation of the transformer 2, and improving the safety of the device. The vibration damping device 8 also includes a fixed plate 85, which is fixedly connected to the side of the grooved bracket 11 away from the side abutment 81. Limiting rails 86 are fixedly connected to the left and right sides of the upper surface of the fixed plate 85. The movable pressure plate 87 is slidably connected to the side surface of the limiting rails 86. The disc-shaped vibration damping spring 88 is fixedly connected to the upper surface of the fixed plate 85. Spring 88 is used to absorb the vertical vibration generated by the oil conservator 1. Pressure rod 89 is fixedly connected to the bottom end of pressure column 12. A torsion spring is provided at the hinge joint of side abutment rod 81 and grooved seat 11. A torsion spring is provided at the hinge joint of rotating shaft 83 and connecting rod 82. The inner arc surface of support plate 84 abuts against the surface of oil conservator 1. Limiting rail 86 is fixedly connected to the side of grooved seat 11 away from side abutment rod 81. The left and right ends of movable pressure plate 87 are slidably connected to the side surface of grooved seat 11. The bottom end of pressure column 12 abuts against the upper surface of movable pressure plate 87. Pressure rod 89 extends from movable pressure plate 87. The upper surface of the fixed plate 85 slides through the lower surface of the movable pressure plate 87, and the pressure rod 89 slides through the lower surface of the movable pressure plate 87 from the upper surface of the fixed plate 85. The top of the disc-shaped vibration-absorbing spring 88 abuts against the lower surface of the movable pressure plate 87, and the bottom of the disc-shaped vibration-absorbing spring 88 is restricted by the fixed plate 85 and thus contracts, so that the vibration transmitted vertically upward by the oil conservator 1 can be more effectively transmitted to the disc-shaped vibration-absorbing spring 88. The disc-shaped vibration-absorbing spring 88 can absorb the vibration transmitted vertically upward by the oil conservator 1, further improving the stability of the oil conservator 1 and ensuring the safe operation of the device.

[0025] Working principle: When the oil conservator 1 is installed on the grooved bracket 11 and the cantilever 3, its surface abuts against the support plate 84. After the support plate 84 is in contact with the oil conservator 1, it is subjected to pressure and rotates on the connecting rod 82 via the rotating shaft 83, thus further conforming to the surface angle of the oil conservator 1. After the support plate 84 is pressed, the pressure is transmitted to the side abutment rod 81 through the rotating shaft 83 and the connecting rod 82. The side abutment rod 81 is then subjected to the torsion force of the torsion spring and always keeps in contact with the oil conservator 1, thereby clamping the oil conservator 1. When the oil conservator 1 is affected by the operation of the transformer 2 and transmits vibration, the support plate 84 is affected by the torsion spring and thus generates a reaction force with the oil conservator 1, thereby absorbing the vibration transmitted by the oil conservator 1 and reducing the radial vibration of the oil conservator 1. The dynamic effect makes the oil conservator 1 more stable during the operation of the transformer 2, improving the safety of the device. When the oil conservator 1 is installed on the grooved bracket 11, it drives the pressure column 12 to descend. After the pressure column 12 contacts the movable pressure plate 87, it drives it to slide and press down between the limit rails 86. After the movable pressure plate 87 presses down, it squeezes the disc-shaped vibration-absorbing spring 88. The bottom end of the disc-shaped vibration-absorbing spring 88 is restricted by the fixed plate 85 and thus contracts, so that the vertical vibration transmitted by the oil conservator 1 can be more effectively transmitted to the disc-shaped vibration-absorbing spring 88. The disc-shaped vibration-absorbing spring 88 can absorb the vertical vibration transmitted by the oil conservator 1, further improving the stability of the oil conservator 1 and ensuring the safe operation of the device.

[0026] Please refer to Figures 1-7. In another embodiment of the present invention, based on the above embodiments, the anti-sway device 9 includes a bracket 91, which is fixedly connected to the upper surface of the transformer 2. The bracket 91 is used to quickly connect the connecting pipe 4 to the transformer 2. A slide rail 94 is fixedly connected to the upper rear surface of the transformer 2. The bottom of the telescopic plate 92 is slidably connected to the inner surface of the slide rail 94. A positioning clamp 93 is fixedly connected to the free end of the top of the telescopic plate 92. The end of the connecting pipe 4 away from the oil tank 1 is clamped on the bracket 91, thereby quickly aligning the connecting pipe 4 with the transformer 2 and maintaining relative movement with the transformer 2, avoiding the connecting pipe 4 from swinging and causing damage to itself, and improving the safety of insulating oil transportation. The two positioning clamps 93 are close together and clamp the connecting pipe 4 to prevent the connecting pipe 4 from detaching from the bracket 91, further improving the safety during oil transportation. The anti-sway device 9 also includes a connector 95. The positioning hoop 93 is fixedly connected to the bottom outer arc surface of the positioning hoop 93. The rear side of the connecting piece 95 is fixedly connected to the guide rod 96. The elastic telescopic rod 97 is fixedly connected to the inner surface of the fixing plate 85. The bottom free end of the elastic telescopic rod 97 is fixedly connected to the connecting frame 98. The inclined groove guide frame 99 is fixedly connected to the top of the connecting frame 98. The inner arc surface of the positioning hoop 93 abuts against the circumferential surface of the connecting pipe 4. The top inner arc surface of the bracket 91 abuts against the circumferential surface of the connecting pipe 4. The bottom end of the pressure rod 89 abuts against the rear upper surface of the connecting frame 98. The guide rod 96 is slidably connected to the inner surface of the inclined groove guide frame 99. The connecting piece 95 drives the positioning hoop 93 to move closer to each other and automatically clamps the connecting pipe 4, which improves the ease of use of the device. The connecting piece 95 drives the positioning hoop 93 to move away from each other and automatically releases the connecting pipe 4, which makes it convenient to remove the oil tank 1 and the connecting pipe 4 from the transformer 2 at the same time, further improving the ease of use of the device.

[0027] Working Principle: Due to the vibration of the oil conservator 1, the connecting pipe 4 may sway during use, posing a risk of damage or even breakage. During the installation of the oil conservator 1, the oil conservator 1 drives the connecting pipe 4 to descend, causing the end of the connecting pipe 4 away from the oil conservator 1 to be secured to the bracket 91. This quickly aligns the connecting pipe 4 with the transformer 2, maintaining relative movement with the transformer 2 and preventing damage caused by the swaying of the connecting pipe 4, thus improving the safety of insulating oil transportation. After the connecting pipe 4 is connected to the bracket 91, it pushes the two telescopic plates 92 and the positioning clamps 93 to slide and move closer to each other within the slide rail 94, causing the two positioning clamps 93 to fit together and clamp the connecting pipe 4, preventing the connecting pipe 4 from detaching from the bracket 91, further improving the safety of the oil transportation process. When the pressure column 12 descends, it drives the pressure rod 89 to descend as well. The pressure rod 89 and the connecting pipe 89... When the connecting frame 98 contacts, it is pushed down. When the connecting frame 98 descends, the free end of the elastic telescopic rod 97 extends downward and drives the inclined groove guide frame 99 to descend. The inclined groove guide frame 99 pushes the two guide rods 96 closer to each other through the guide of the inner inclined surface. The guide rods 96 then drive the positioning clamps 93 closer to each other through the connector 95 and automatically clamp the connecting pipe 4, which improves the ease of use of the device. When the pressure rod 89 rises, the connecting frame 98 rises under the influence of the elastic reset effect of the elastic telescopic rod 97 and drives the inclined groove guide frame 99 to rise. The inclined groove guide frame 99 then pushes the two guide rods 96 away from each other through the guide of the inner inclined surface. The guide rods 96 then drive the positioning clamps 93 away from each other through the connector 95 and automatically release the connecting pipe 4, which makes it convenient to remove the oil tank 1 and the connecting pipe 4 from the transformer 2 at the same time, further improving the ease of use of the device.
