Dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. The cooling methods are divided into natural air cooling and forced air cooling. Dry-type transformers are transformers with high electrical strength, mechanical strength, and heat resistance. They are excellent products for urban power grid transformation. Since dry-type transformers have many advantages such as reducing fire hazards, less operation and maintenance and overhaul workload, and no pollution or environmental impact, they are widely used in places with high fire protection requirements, important buildings with dense personnel, and main workshops of enterprises.

The horizontal plane height of the top of the weighing sensor is higher than the horizontal plane height of the top of the fixed base plate. There is a gap between the bottom end of the load-bearing plate and the top end of the fixed base plate. The thickness of the limit support block is the same as the height dimension of the gap.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. A vibration monitoring mechanism is provided. The contact block is pressed against the lower bonding plate to transmit the up and down vibrations caused by the loosening of the mounting seat outward. After the mounting seat shakes up and down, it will push the contact block and the rotating short rod to deflect upward, push the rotating long rod and the stainless steel ball to fall, and under the action of the counterweight block at the bottom of the rotating short rod, the rotating short rod automatically falls, pushing the rotating long rod and the stainless steel ball to rise and hit the stainless steel block, and then the stainless steel ball and the stainless steel block are used to contact and hit each other to show the vibration of the mounting seat. The large vibration amplitude of the mounting seat will increase the upward deflection amplitude of the rotating short rod, and the increase in the falling distance of the rotating long rod and the stainless steel ball will increase the impact force on the stainless steel block, so that the sound size of the collision between them will change. The noise meter can transmit and distinguish the sound size generated when the stainless steel ball and the stainless steel block are in contact, so that the staff can timely understand the stability of the mounting seat to prevent the vibration caused by the long-term use of the transformer from causing the mounting seat to loosen. Timely stable maintenance can reduce the probability of the transformer being damaged and unusable. At the same time, the length of the rotating long rod is longer than that of the rotating short rod. When the vibration amplitude of the mounting base is transmitted, the vibration amplitude will be amplified by utilizing the different lengths of the swing arm. The monitoring method is more accurate and can capture in time after a slight change in the vibration of the mounting base. Both the stainless steel ball and the stainless steel block are made of stainless steel alloy. The sound produced by collision with each other is crisper and louder. Therefore, the noise meter can accurately capture the impact sound among the various noises when the transformer is running. The alarm reminds the staff so that when the staff arrives around the transformer, they can determine the precise location of the transformer that needs maintenance.

[0015] 2. Use the bonding block to stick to one end of the upper bonding plate to monitor the overall front-to-back stability of the mounting seat. When the mounting seat is loose, it will produce a certain amount of front-to-back shaking, pushing the bonding block and the movable square rod to one side, and the driving block moves with the movable square rod. Use the pressure sensor to monitor the position of the driving block to determine whether the movable square rod is moving and the magnitude of the offset. The greater the pressure felt by the pressure sensor, the farther the movable square rod is pushed, and then it is understood that the overall front-to-back shaking of the mounting seat is greater, so that the staff can maintain the mounting seat in time to prevent the shaking of the transformer internal parts from being damaged or the connection line from falling off due to the failure to deal with it in time, which provides great convenience for the staff to find the transformer fault problem; The buffer pad and the movable cylinder protect the pressure sensor, so that the pressure sensor has a certain buffer activity space when it is squeezed, preventing the driving block from continuously squeezing the pressure sensor and causing damage to it. The elastic metal sheet resets the movable square rod. After the movable square rod is pushed and deflected, it is pushed forward again to contact the upper bonding plate, so that continuous monitoring can be carried out. The pressure sensor can sense the pressure multiple times to improve the accuracy of detection.

[0016] 3. Use a noise meter to monitor the noise of the mounting base shaking up and down, and a pressure sensor to monitor the amplitude of the mounting base shaking forward and backward. The stability of the mounting base is monitored from two different directions and two different detection methods, which improves the accuracy of the detection and reduces the error rate of the detection results. Both monitoring methods can control the hydraulic telescopic rod. If the mounting base is found to be loose, the position of the lifting plate and the support column is adjusted so that the compression pad is close to the top of the winding, and the pressing pad is pressed against the top of the mounting base, thereby assisting in tightening and stabilizing the mounting base and the winding as a whole, improving the stability of the mounting base and the winding, and providing a certain amount of stabilization time for maintenance staff.

[0017] 4. A safety protection mechanism is set up, and the load-bearing plate and weighing sensor are used to monitor the environmental changes around the bottom of the transformer. When foreign objects or small animals approach the transformer, the signal is fed back in time, and the electric push rod is controlled to pull the sealing round block up to expose the end of the fixed cylinder. The noise signal inside the transformer is captured by the microphone and released through the amplifier, which plays a driving role for small animals near the transformer. At the same time, the flash light bar also lights up and flashes, and is also driven to prevent small animals such as mice from approaching and drilling into the transformer to damage its circuits, thereby increasing the service life of the transformer. The sound and light used for driving do not need to run continuously. They will be controlled and started only when foreign objects are detected approaching, reducing the resources required for control operation, preventing the light and sound from starting to produce useless work, and reducing energy consumption while playing a protective role, reflecting a certain environmental protection and energy-saving concept; A fixed cylinder is used to correspond to the winding, and a sound sensor can monitor the winding. When noise is generated inside the winding, information feedback is provided in a timely manner to prevent the internal components of the winding from loosening and causing abnormalities that make the subsequent transformer unusable as a whole. Timely maintenance when an abnormality occurs inside can prevent the fault from being amplified and reduce the loss caused by transformer damage.

[0018] 5. The position of the limit support block can be adjusted by using the positioning column and the cross operating block. When the transformer is under protection monitoring, the limit support block is away from the load-bearing plate. When the staff needs to work close to the transformer box, the limit support block is embedded in the gap between the load-bearing plate and the fixed bottom plate, which supports and stabilizes the load-bearing plate and supports the pressure caused by the staff stepping on the load-bearing plate, thereby protecting the weighing sensor.

[0019] In summary, through the vibration monitoring mechanism and the safety protection mechanism, the stability of the mounting base is monitored to judge and detect the operating status of the internal structure of the transformer. In the event of shaking, a signal can be obtained in time for maintenance to prevent the shaking from worsening and causing damage to the internal structure and components of the transformer, thereby improving the safety of the transformer and preventing the transformer from being damaged by continuous operation under adverse conditions such as shaking. At the same time, the environment around the transformer box is monitored to reduce the chance of damage to the transformer line, thereby further improving the safety of the transformer.

By using the contact block 510 to be tightly attached to the lower bonding plate 502, the up and down vibrations generated by the loosening of the mounting seat 3 can be directed outwards. The transmission, after the mounting seat 3 shakes up and down, it will push the contact block 510 and the rotating short rod 509 to deflect upward, push the rotating long rod 511 and the stainless steel ball 513 to fall, and under the action of the counterweight block 534 at the bottom of the rotating short rod 509, the rotating short rod 509 automatically falls, pushing the rotating long rod 511 and the stainless steel ball 513 to rise and hit the stainless steel block 514, and then the stainless steel ball 513 and the stainless steel block 514 are used to contact and hit each other to show the vibration of the mounting seat 3.

A transparent protective plate 611 is fixedly installed on the top of the groove 615. The load-bearing plate 614 and the weighing sensor 613 are used to monitor the environmental changes around the bottom of the transformer. When foreign objects or small animals approach the transformer, The signal is fed back to the outside in time, and the electric push rod 607 is controlled to pull the sealing round block 609 upward to expose the end of the fixed cylinder 601. The noise signal inside the transformer is captured by the microphone 604 and released to the outside through the amplifier 605, which plays a driving role for small animals near the transformer. At the same time, the flash light bar 616 also lights up and flashes, and is also driven to prevent small animals such as mice from approaching and drilling into the transformer to damage its circuit, thereby increasing the service life of the transformer. The sound and light used for driving do not need to run continuously, and will only be controlled to start when a foreign object is detected approaching, thereby reducing the resources required for control operation, preventing the light and sound from starting to produce useless work, and reducing energy consumption while playing a protective role, which embodies a certain environmental protection and energy-saving concept; Both ends of the two sides of the fixed bottom plate 610 are fixedly installed with fixed cylinders 617, and a positioning column 618 is rotatably installed in the middle of the top of the fixed cylinder 617. A limited support block 619 is fixedly installed in the middle of the positioning column 618, and a cross operating block 620 is fixedly installed on the top of the positioning column 618. The horizontal plane height of the top of the weighing sensor 613 is higher than the horizontal plane height of the top of the fixed bottom plate 610. There is a gap between the bottom end of the load-bearing plate 614 and the top of the fixed bottom plate 610, and the thickness of the limited support block 619 is the same as the height dimension of the gap. The position of the limit support block 619 can be adjusted by using the positioning column 618 and the cross operating block 620. When the transformer is under protection monitoring, the limit support block 619 is away from the load-bearing plate 614. When the staff needs to work close to the transformer box 1, the limit support block 619 is embedded in the gap between the load-bearing plate 614 and the fixed bottom plate 610, which supports and stabilizes the load-bearing plate 614, supports the pressure caused by the staff stepping on the load-bearing plate 614, and thus protects the weighing sensor 613.

[0024] The working principle and use process of the present invention are as follows: First, when the transformer is in operation, the whole transformer will generate certain vibrations. The fixed vertical plate 501 and the lower bonding plate 502 will vibrate together with the mounting seat 3. The contact block 510 is close to the lower bonding plate 502. When the lower bonding plate 502 vibrates up and down with a certain amplitude, it will push the contact block 510 and the rotating short rod 509 to deflect upward by a certain amplitude. The rotating short rod 509 deflects upward around the positioning axis 507, pushing the rotating long rod 511 and the connecting block 512 to deflect downward. The weight block 534 pulls the rotating short rod 509 downward to return to its original position by its own gravity, pushing the rotating long rod 511 and the connecting block 512 to deflect upward. The stainless steel ball 513 will hit the bottom end of the stainless steel block 514 upward. The noise meter 515 captures the noise generated by the impact and determines whether the noise meets a certain standard. When the vibration amplitude of the mounting base 3 is within the normal range, the distance that the contact block 510 and the rotating short rod 509 are pushed upward is small, and then the force of the stainless steel ball 513 hitting the stainless steel block 514 from below is small, and the noise generated is small, indicating that the mounting base 3 is still stable. If the connection and fixation between the mounting base 3 and the transformer box 1 is loose to a certain extent, it will cause the mounting base 3 to shake up and down more, and then push the contact block 510 to rise to an increased height, and fall under the action of the counterweight block 534, and the height of the fall increases. The gravity of the falling contact block 510, the rotating short rod 509 and the counterweight block 534 acts on the rotating long rod 511, and the rotating long rod 511 and the connecting block 512 deflect upward. The force of the stainless steel ball 513 hitting the bottom of the stainless steel block 514 increases, and then the sound generated increases. If the noise captured by the noise meter 515 exceeds a certain range, and the subsequent detection continues to exceed the range, it indicates that the mounting base 3 is unstable and the staff needs to perform maintenance in time. At the same time, the fitting block 519 at one end of the movable square rod 518 is tightly attached to the upper fitting plate 503 to monitor the front and rear stability of the mounting seat 3. When the transformer vibrates during operation, the mounting seat 3 will shake forward and backward to a certain extent. When the mounting seat 3 shakes, the upper fitting plate 503 will push the fitting block 519 and the movable square rod 518 to deviate outward, and the movable square rod 518 moves along the guide cylinder 517 to the inside of the fixed box 520, and the driving block 522 moves therewith, which will cause a certain pressure on the end of the pressure sensor 526. The movable cylinder 524 will move backward along the connecting vertical plate 523, and the buffer cushion 527 will be squeezed to provide buffer protection for the pressure sensor 526 when it is squeezed. The elastic metal sheet 521 will push the movable square rod 518 to move toward the inside of the transformer box 1, so that the movable square rod 518 moves back and forth with the vibration of the mounting seat 3, and continuously generates pressure on the pressure sensor 526. If the pressure sensed by the pressure sensor 526 is within the normal range, it indicates that the distance that the movable square rod 518 moves forward and backward is small, which is a normal phenomenon, and the amplitude of the mounting seat 3 shaking forward and backward is also within the normal range. If the pressure sensed by the pressure sensor 526 exceeds the normal range, and the subsequent continuously detected pressures are all beyond the range, the offset distance of the movable square rod 518 increases, indicating that the amplitude of the mounting seat 3 shaking forward and backward increases, and the mounting seat 3 and the winding 4 are in an unstable state. The fault signal is transmitted to the outside in time for the staff to perform maintenance. At the same time, the fixed cylinder 601 is used to align the winding 4 one by one, and the sound sensor 602 is also aligned with the winding 4. The sound sensor 602 can be used to capture and transmit the sound generated by the winding 4. If the parts inside the winding 4 become loose and fall off, the winding 4 will increase new noise. The sound sensor 602 captures and transmits the sound signal. If there is an obvious difference, the staff can perform maintenance in time. Then, when the signals sensed by the noise meter 515 and the pressure sensor 526 are both beyond the normal range, the hydraulic telescopic rod 529 can be controlled to extend downward, pushing the lifting plate 530 and the support column 532 down, so that the pressing pad 531 is pressed tightly against the top of the winding 4, and the pressing pad 533 is pressed tightly against the edge of the top of the mounting seat 3, which presses and stabilizes the mounting seat 3 and the winding 4 in a short time, providing enough time for the staff to arrive and perform maintenance, thereby preventing the transformer from malfunctioning and being damaged before the maintenance is completed; When the transformer is running, the surrounding area is kept empty. The cross operating block 620 is used to rotate and adjust the positioning column 618 and the limit support block 619 so that the limit support block 619 is away from the load-bearing plate 614. The load-bearing plate 614 and the weighing sensor 613 are used to monitor the surrounding environment of the transformer box 1. If small animals such as mice approach and step on the surface of the load-bearing plate 614, a certain pressure will be caused to the weighing sensor 613, and then the weighing sensor 613 transmits the signal outward, and the electric push rod 607 is started, pulling the connecting rod 608 and the sealing round block 609 to move upward, exposing the port of the fixed cylinder 601, and using the microphone 604 to capture the noise signal inside the transformer box 1 and transmit it to the amplifier 605. The amplifier 605 amplifies and plays the sound, thereby playing a noise-driven processing for the small animals close to the transformer box 1. At the same time, the flash light bar 616 emits light and flashes, and drives them away by sound and light to prevent the small animals from entering the transformer and damaging its circuits; After driving away the animals for a period of time, the electric push rod 607 extends downward, pushing the sealing round block 609 to fit with the arc-shaped sealing block 606, closing the end of the fixed cylinder 601, and the microphone 604, amplifier 605 and flash light bar 616 all stop running. They are powered on and started only when the animals approach, and remain powered off when idle, reducing the resources required for continuous power use, which is more environmentally friendly.
