Technical Field

[0001] The invention relates to the technical field of voltage transformers, in particular to an intelligent voltage transformer. Background Art

[0002] Intelligent voltage transformer is a new type of voltage transformer equipment with intelligent functions. It adopts advanced sensing technology, digital signal processing technology and communication technology, and can realize high-precision measurement, intelligent control and remote monitoring of voltage. Intelligent voltage transformer is usually composed of primary winding, secondary winding, iron core, insulation structure, electronic measurement unit and communication interface. The primary winding is connected to the high voltage system to be measured, receives high voltage signal, and senses high voltage to the secondary winding through the magnetic coupling of the iron core. The secondary winding converts the sensed high voltage into low voltage signal according to a certain ratio for measurement and processing by the electronic measurement unit. The electronic measurement unit adopts high-precision sensors and digital signal processors, which can quickly and accurately measure and analyze voltage signals, and upload the measurement results to the remote monitoring system through the communication interface. Intelligent voltage transformer has the advantages of high measurement accuracy, high intelligence, strong communication function and high reliability. It is widely used in smart grid, new energy power generation, industrial automation and other fields.

[0003] A Chinese patent with the announcement number "CN220189380U" discloses an intelligent voltage transformer, which includes a placement plate and a voltage transformer body arranged at the lower end of the placement plate; when using the intelligent voltage transformer, the mounting plate is first fixed to the external device through the mounting hole and bolts, and then the voltage transformer body is inserted into the card block through the card slot. When the card block is completely inserted into the card slot, the through hole inside the fixing plate will be aligned with the connecting holes on the left and right sides of the voltage transformer body. At this time, the fastening nut is inserted into the through hole and the connecting hole. The fastening nut is connected with the connecting hole and the internal thread inside the through hole through the external thread of the outer wall to fix the fixing plate and the voltage transformer body, so that the voltage transformer body is installed on the upper end of the mounting plate. Through the coordinated use of the card block and the card slot, the voltage transformer body can be pre-fixed, avoiding the need to spend a lot of time on the alignment of the through hole and the connecting hole;

[0004] In the actual use of the above-mentioned device, bolts are generally used as an auxiliary installation method. However, it must be admitted that this installation method has many obvious disadvantages;

[0005] First, from the installation point of view, bolt installation cannot achieve the quick clamping installation of the transformer in actual operation, which makes the installation process complicated and time-consuming, greatly reducing the convenience and efficiency of the installation operation. Installers often need to spend a lot of time and energy to tighten and adjust the bolts, which not only increases the labor intensity, but also may cause unstable installation quality due to improper operation. Secondly, although the overall structure of the transformer is relatively compact, which saves space to a certain extent, this compact structure becomes an obstacle when it is necessary to inspect and maintain its interior. Since it is difficult to quickly disassemble the casing of the transformer, the maintenance personnel face huge difficulties when conducting internal inspections and repairs. It is difficult, they need to spend a lot of time to remove the bolts, and the internal structure of the transformer may be damaged during the removal process, which not only increases the time cost of inspection and maintenance, but also may affect the normal operation of the equipment, reduce the reliability and service life of the equipment. Moreover, from the perspective of the overall application, whether it is installation, protection, or subsequent inspection and maintenance work, it is extremely cumbersome and inconvenient because of the bolt installation method. During the installation process, it is necessary to accurately align the bolt holes and tighten the bolts, which has certain requirements for the installation environment and installation tools. In terms of protection, it lacks the corresponding protective buffer structure, and the seismic performance during specific application is poor, so it needs to be improved. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The invention provides a clamping mechanism, which greatly improves the convenience and stability of the device. When in use, the bridge handrail is pulled out to drive the slide plate to move down. At this time, the sealing door covers the front side of the transformer housing, and the limiting arm at the bottom of the sealing door is inserted into the installation slot. After the handrail is released, the limiting spring is reset to make the slide plate move up, driving the clamping block at the end of the clamping arm to be inserted into the clamping slot to realize the clamping installation of the sealing door. During the installation process, the movement of the slide plate drives the rack to move, meshing with the gear to make the gear rotate, and then driving the turntable to drive the arc-shaped limiting hook to accurately insert into the limiting hole set in the arc-shaped concentric circle, and the sealing door is reinforced by the arc-shaped limiting hook and the fixed shaft.

[0020] Secondly, in the present invention, the buffer mechanism is used to enhance the buffer performance of the device. During the application of the device, when the transformer housing vibrates, the buffer spring cooperates with the damper to buffer and resist vibration, so that the device as a whole has a strong buffer performance. The damper is arranged between the bottom bracket and the mounting plate, which can reduce the amplitude of the buffer spring and improve the buffer and shock resistance performance. In addition, the hoisting bracket cooperates with the side buffer spring, and when the bottom bracket shakes, the side buffer spring is pulled to expand and contract for buffering, and the buffer spring and the buffer spring work together to further improve the overall buffer performance.

When in use, the installation plate is attached to the steel frame, the crank is held to rotate the screw rod, and the slider is driven to slide in the strip groove. Since the threads at both ends of the screw rod have opposite rotation directions, the slider can be synchronously driven to slide back and forth during rotation, driving the clamping frame to move relative to each other and clamp the steel frame, so that the transformer housing is stably installed in the required position, and then the hand-tightening screw is twisted to insert the positioning hole to lock and fix it. After the crank is fixed, the screw rod is clamped to ensure that the clamping frame stably clamps the steel frame. When disassembling and inspecting, loosen the hand-tightening screw, pull the crank again to rotate the screw rod to drive the slider to move outward, adjust the clamping frame to move outward, facilitate quick disassembly and assembly of the inspection and repair device, and improve the overall convenience of use.

The top of the outer surface of the turntable 521 away from the gear 524 is fixedly connected with an arc-shaped limiting hook 527, and the arc-shaped limiting hook 527 is inserted into the inner part of the limiting hole 525. In the connecting assembly 53, the limiting spring 533 in the slide groove 531 cooperates with the slide plate 534, so that when the sealed door 3 is installed, the limiting spring 533 can be reset after the bridge handrail 55 is released, and the slide plate 534 can be pulled upward, thereby driving the clamping block 536 on the top of the clamping arm 535 to insert into the clamping groove 532, so as to realize the rapid clamping installation of the sealed door 3. This design is convenient and efficient to operate, and does not require complicated installation steps. In the limiting assembly 52, the gear 524 on the outer side of the turntable 521 is meshed and connected with the rack 526 on the outer side of the connecting frame 522. The movement of the slide plate 534 drives the rack 526 to move, thereby driving the gear 524 to rotate. The turntable 521 drives the arc-shaped limit hook 527 to rotate and accurately insert it into the limit hole 525 in the middle of the fixed shaft 523. Since the limit hole 525 and the arc-shaped limit hook 527 are arranged in arc-shaped concentric circles, this design not only realizes the stable reinforcement of the sealed door 3, but also when it is necessary to disassemble and inspect the inside of the transformer housing 1, it is only necessary to pull the bridge handrail 55 downward.

This ensures that the arc-shaped limit hook 527 can be inserted into the limit hole 525 very accurately when the turntable 521 rotates, so as to achieve sealing The stable reinforcement of the door 3 improves the firmness and reliability of the sealed door 3 after installation. Secondly, the supporting rails 528 on both sides of the lower end of the transformer housing 1 are slidably connected to the supporting rods 529 on the top of the connecting frame 522. During the adjustment of the device, the cooperation of the supporting rods 529 and the supporting rails 528 can assist in supporting and reinforcing the connecting frame 522, further improving the overall stability of the rack 526, the arc-shaped limit hook 527 and the fixed shaft 523, making the entire device more stable and reliable during use. Furthermore, the connecting frame 522 and the bridge handrail 55 on the outside of the sealed door 3 facilitate operation. Whether it is installing the sealed door 3 or disassembling and repairing it, the corresponding operation can be easily achieved by pulling out the bridge handrail 55, which greatly improves the convenience of operation. The anti-slip handrail cover on the outer surface of the bridge handrail 55 increases friction to prevent hand slippage during operation.

[0037] The working principle of the present invention is as follows: in the present invention, the carefully arranged card installation mechanism 5 plays a vital role. When the device is put into use, the user can pull the bridge handrail 55, thereby driving the slide plate 534 to move downward. During this process, the slide plate 534 will pull the limit spring 533, and then the sealing door 3 will be covered on the front side of the transformer housing 1. At this time, the limit arm 54 at the bottom of the sealing door 3 can be smoothly inserted into the inner side of the installation groove body 51. When the sealing door 3 is installed, the bridge handrail 55 is released, the limit spring 533 will be reset and pull the slide plate 534 to move upward. The upward movement of the slide plate 534 will drive the card block 536 at the end of the card arm 535 to be inserted into the inner side of the card slot 532. In this way, the card installation of the sealing door 3 is realized.

[0038] During installation, the movement of the slide plate 534 will drive the rack 526 at the outer end of the connecting frame 522 to move. Since the rack 526 and the gear 524 are meshed and connected, as the rack 526 slides, the gear 524 will rotate, and the rotation of the gear 524 will drive the turntable 521 to rotate, and the rotation of the turntable 521 can drive the arc-shaped limiting hook 527 to rotate and insert it into the inner side of the limiting hole 525. It is worth noting that the limiting hole 525 and the arc-shaped limiting hook 527 are both arranged in arc-shaped concentric circles, which makes the rotation of the turntable 521 can very accurately drive the arc-shaped limiting hook 527 to be inserted into the inner side of the limiting hole 525, and the mutual limitation of the arc-shaped limiting hook 527 and the fixed shaft 523 can stably reinforce the clamping sealing door 3;

[0039] If it is necessary to disassemble the sealing door 3 in order to inspect the interior of the transformer housing 1, it is only necessary to pull the bridge handrail 55 downward. At this time, on the one hand, the downward movement of the slide plate 534 can directly drive the clamping arm 535 to move downward, so that the clamping block 536 and the clamping groove 532 are separated; on the other hand, the downward movement of the rack 526 can drive the gear 524 to rotate in the opposite direction, so that the arc-shaped limiting hook 527 can be turned out from the inner side of the limiting hole 525. In this way, the sealing door 3 can be quickly disassembled and assembled, and during the adjustment process, the sliding arrangement of the supporting rod 529 and the supporting rail 528 can assist in supporting and reinforcing the connecting frame 522, further improving the overall stability of the rack 526, the arc-shaped limiting hook 527 and the fixed shaft 523, so that the device as a whole has strong stability, is convenient for rapid disassembly and maintenance, and greatly facilitates the inspection and maintenance of the interior of the transformer housing 1;

[0040] The buffer mechanism 4 provided in the present invention brings significant advantages to the application of the device. During the application of the device, when the transformer housing 1 vibrates, the buffer spring 42 cooperates with the damper 46 to assist in buffering and shock resistance, which makes the device as a whole have a strong buffering performance. The setting of the damper 46 plays a key role. It can assist in buffering between the bottom bracket 41 and the mounting plate 21, reduce the amplitude of the buffer spring 42, and improve its buffering and shock resistance performance as a whole.

[0041] In addition, during use, the arrangement of the hoisting bracket 45 and the side buffer spring 44 is also very clever. When the bottom bracket 41 shakes, the side buffer spring 44 can be pulled to perform telescopic buffering. The buffer spring 42 cooperates with the side buffer spring 44 to further improve the overall buffering performance of the device.

[0042] By setting the mounting mechanism 2, the device can show excellent performance during use. The mounting plate 21 can be attached to the steel frame required for installation. At this time, the screw rod 23 is pulled and rotated by holding the crank 263. As the screw rod 23 rotates, the slider 24 can be driven to slide inside the strip groove 22. Since the threads at both ends of the screw rod 23 rotate in opposite directions, as the screw rod 23 rotates, the slider 24 can be driven to slide back and forth inside the strip groove 22. The rotation of the screw rod 23 can synchronously drive the slider 24 to slide back and forth inside the strip groove 22. Through the reciprocating sliding of the slider 24, the clamping frame 25 can be synchronously driven to move relative to each other.

[0043] The clamping frame 25 can be mutually displaced to clamp and hook the steel frame to be installed, so that the transformer housing 1 as a whole can be relatively stably installed at the desired position. At this time, by twisting the hand-tightening screw 264, the hand-tightening screw 264 is inserted into the inner side of the positioning hole 262 at the corresponding position, and then the hand-tightening screw 264 is inserted into the interior of the positioning hole 262, and then it can be locked and fixed. The crank 263 is fixed to stably clamp the fixing screw 23, so that the clamping frame 25 can be stably clamped and installed at the steel frame at the desired installation position, and the overall installation stability is strong during use;

[0044] Furthermore, when maintenance and disassembly are required during use, it is only necessary to loosen the hand-tightened screw 264 so that the hand-tightened screw 264 will be separated from the positioning hole 262. At this time, the crank 263 can be pulled again to rotate, so that the screw rod 23 can drive the slider 24 to move outward, and then the clamping frame 25 can be adjusted to move outward, which is convenient for quick disassembly and maintenance of the device, and can improve the overall convenience of use of the device.
