Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more specifically, to a transformer tilt detection device and detection method. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage. Its core functions include voltage transformation, current transformation, and impedance matching.

[0003] After the transformer is installed, a tilt detection device will monitor it in real time. Currently, the transformer tilt detection device mainly uses infrared sensors to detect whether the transformer has shifted. If displacement is detected, it indicates that the transformer body has tilted, but it cannot detect the direction of the tilt. Therefore, it cannot deduce which internal components of the transformer are easily damaged due to different tilt directions. This requires maintenance personnel to carry various potentially damaged components and prepare to replace them, which causes inconvenience to maintenance personnel. Moreover, since it takes a certain amount of time for maintenance personnel to reach the faulty transformer, the overall tilt of the transformer makes it unstable. Then, under the influence of the tilting force, the transformer may tilt again, causing secondary damage to the transformer. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer tilt detection device and detection method to solve the problems mentioned in the background art.

[0005] A transformer tilt detection device includes a transformer body. First U-shaped support blocks are connected to the lower two sides of the transformer body. Second U-shaped support blocks are connected to the lower two sides of each first U-shaped support block. First semi-circular fixing blocks are connected to the two sides of the end of each second U-shaped support block facing the middle of the transformer body. A utility pole is connected to the end of the first semi-circular fixing block facing the middle of the transformer body. Detection components are connected to the grooves at both ends of each first U-shaped support block. The two first semi-circular fixing blocks are fixed to the surface of the utility pole by a first fixing nut. The detection assembly includes a first connecting rod, a second connecting rod connected to the end of the first connecting rod facing the middle of the transformer body, a first fixing bolt passing through the junction of the first and second connecting rods, a first lateral tilt detection assembly connected to the end of the first connecting rod facing the utility pole, concave connecting blocks connected to both sides of the end of the first lateral tilt detection assembly facing the middle of the transformer body, a second lateral tilt detection assembly connected to the end of the second connecting rod facing the utility pole, convex connecting blocks connected to both sides of the end of the second lateral tilt detection assembly facing the middle of the transformer body, a first fixing rod passing through the overlapping position of the concave and convex connecting blocks, and vertical tilt detection assemblies connected to the upper ends of both sides of the first and second lateral tilt detection assemblies facing the middle of the transformer body, and threads connected to both ends of the first fixing rod, with a fixing nut connected to the outer side of each thread, a groove formed at the end of the first connecting rod facing the second connecting rod, and a second rectangular connecting block connected to the end of the second connecting rod facing the first connecting rod, at which point the fixing bolt passes through the first and second connecting rods and fixes them together.

[0006] Preferably, a first rectangular connecting plate is connected to the gap between the two second U-shaped support blocks, a control box is connected to the lower surface of the first rectangular connecting plate, and an alarm is connected to one end of the control box.

[0007] Preferably, the first lateral tilt detection component includes a second semi-circular fixing block, a third semi-circular fixing block connected to one end of the second semi-circular fixing block facing the first connecting rod, a third connecting rod connected to one end of the third semi-circular fixing block facing the first connecting rod, a circular rotating rod connected to one end of the third connecting rod away from the third semi-circular fixing block, and fourth connecting rods connected to both sides of the end of the third semi-circular fixing block facing the first connecting rod, with the circular rotating rod rotatably connected to the third connecting rod. The second semi-circular fixing block and the third semi-circular fixing block are fixed together by a second fixing nut.

[0008] Preferably, each of the fourth connecting rods has a second U-shaped connecting block connected to the end furthest from the third semi-circular fixing block. Each second U-shaped connecting block has an arc-shaped groove in its inner cavity. A second circular rotating rod is connected to the end of each arc-shaped groove furthest from the circular rotating rod. A rectangular trigger block is connected to the outer surface of each second circular rotating rod. A third rectangular connecting block is connected to the lower end of each rectangular trigger block. A fifth connecting rod is sleeved on the middle portion of the circular rotating rod. A sixth connecting rod is connected to the inner cavity of the fifth connecting rod. A trigger groove is formed on the upper surface of the third rectangular connecting block, and the trigger groove fits into the rectangular trigger block. The rectangular trigger block initially overlaps completely with the trigger groove. The outer side of the third rectangular connecting block is connected to a rectangular frame. An infrared sensor is installed in the inner cavity of the rectangular frame. When the infrared sensor detects that the rectangular trigger block and the trigger groove are not completely aligned, the surface transformer is in a lateral tilt state. This causes the infrared sensor to send a signal to the control box, which then activates the alarm. The alarm signal is then transmitted to the power grid center, allowing the power company to accurately determine the location of the transformer tilt. The end of the fifth connecting rod facing the sixth connecting rod has a second rectangular groove. The width of the sixth connecting rod matches the second rectangular groove. The ends of the fifth and sixth connecting rods away from the circular rotating rod are both connected to the second U-shaped connecting block.

[0009] Preferably, the second semi-circular fixing block, the third semi-circular fixing block, the third connecting rod, the circular rotating rod, the fourth connecting rod, the second U-shaped connecting block, the fifth connecting rod, and the sixth connecting rod together form a stable triangular structure, and the components of the second transverse detection assembly are the same as those of the first transverse detection assembly.

[0010] Preferably, the vertical tilt detection component includes a first rectangular connecting block, a T-shaped connecting block connected to the end of the first rectangular connecting block away from the first U-shaped support block, a seventh connecting rod connected to the lower end of the T-shaped connecting block, a second circular rotating block connected to the lower end of the seventh connecting rod, and a rectangular sealing block connected to the outer surface of the seventh connecting rod.

[0011] Preferably, the seventh connecting rod has a T-shaped groove at one end facing the T-shaped connecting block. A second rectangular connecting plate is connected to the inner cavity of the T-shaped groove. The surface of the second rectangular connecting plate has several circular holes. A circular guide rod is connected to the inner cavity of each circular hole. There is a gap between the T-shaped connecting block and the seventh connecting rod in the initial state. A reset spring is provided on the lower end surface of each circular guide rod. The second circular rotating block is connected to the second circular rotating rod, and the upper end of the reset spring is fixed to the lower end surface of the second rectangular connecting plate. A second infrared sensor is connected to the inner cavity of the rectangular sealing block. If the second infrared sensor detects that the gap between the T-shaped connecting block and the seventh connecting rod is closed, the main body of the surface infrared sensor will be vertically tilted.

[0012] Preferably, the detection method of the transformer tilt detection device includes the following steps: S1. When the transformer body is tilted laterally due to earthquakes, foundation settlement, or external impacts, a deflection force is generated on the first rectangular connecting block, causing the vertical tilt detection component to rotate around the second circular rotating block. This, in turn, causes the second circular rotating rod to rotate. As the second circular rotating rod rotates, it causes the rectangular trigger block to rotate, resulting in the rectangular trigger block and the trigger groove on the upper surface of the third rectangular connecting block not being completely aligned. This indicates that the transformer is tilted laterally. When the infrared sensor detects that the rectangular trigger block and the trigger groove are not completely aligned, it sends a signal to the control box, which then activates the alarm. The alarm signal is transmitted to the power grid center, allowing the power company to accurately determine the location of the transformer tilt. Based on the location of the infrared sensor signal, the direction of the transformer body tilt is determined, and the probability of damage to internal components is calculated. Maintenance personnel are then dispatched to the destination for maintenance. S2. If the transformer body continues to tilt during the arrival of maintenance personnel, when the seventh connecting rod in the vertical tilt detection component contacts both ends of the second U-shaped connecting block, the second semi-circular fixing block, the third semi-circular fixing block, the third connecting rod, the circular rotating rod, the fourth connecting rod, the second U-shaped connecting block, the fifth connecting rod, and the sixth connecting rod will form a stable triangular structure to fix the transformer body and prevent the transformer body from tilting further. S3. If the transformer body is vertically tilted due to earthquakes, foundation settlement, or external impacts, it will generate a forward or backward pressure. At this time, the T-shaped connecting block in the vertical tilt detection component on the side under pressure will move downward along the T-shaped groove, thereby causing the second rectangular connecting plate to move downward along the circular guide rod, which in turn causes the reset spring to retract. When the gap between the T-shaped connecting block and the seventh connecting rod closes, the upper part of the circular guide rod will coincide with the circular hole. At this time, the triangular stabilizing structure formed by the detection components at both ends will provide support for the tilted side of the transformer body, preventing the transformer body from continuing to tilt. S4. When the second infrared sensor detects that a gap between the T-shaped connecting block and the seventh connecting rod is closed, the second infrared sensor sends a signal to the control box, which then activates the alarm. The alarm signal is transmitted to the power grid center, allowing the power company to accurately pinpoint the location of the transformer tilt. Based on the location of the infrared sensor signal, the direction of the transformer's tilt is determined, and the probability of damage to internal components is calculated. Maintenance personnel are then dispatched to the location to perform repairs until the transformer is successfully repaired, at which point all operations are complete.

[0013] Compared with the prior art, the advantages of this invention are: 1. In this invention, through the linkage design of lateral and vertical tilt detection components, infrared sensors are used to capture the positional changes of the rectangular trigger block and the trigger groove, as well as the closure state of the gap between the T-shaped connecting block and the seventh connecting rod, to accurately distinguish between lateral and vertical tilt. For example, when tilted laterally, the rectangular trigger block rotates, and when tilted vertically, the T-shaped structure displaces. The two states correspond to different vulnerable internal components: such as lateral tilt threatening the bushing or vertical tilt affecting the tap changer. This allows maintenance personnel to predict faulty components in advance, carry spare parts as needed, avoid multiple rounds of repairs due to insufficient spare parts, significantly improve maintenance efficiency, and reduce maintenance costs.

[0014] 2. In this invention, emergency reinforcement is achieved by constructing a self-stabilizing triangular structure. When tilted laterally, the seventh connecting rod triggers the second U-shaped connecting block, driving the second semi-circular fixing block, the third connecting rod, and other components to form a triangular support to counteract the tilting force. When tilted vertically, through the linkage of the reset spring and the circular guide rod, when the gap between the T-shaped connecting block and the seventh connecting rod is closed, the triangular structure automatically provides a reverse support force. This real-time dynamic protection can effectively curb the continuous tilting of the transformer, reduce secondary damage such as winding displacement and insulating oil leakage, and build a solid defense for the safe operation of the equipment.

[0015] 3. In this invention, through the intelligent monitoring link of infrared sensor-control box-alarm, once tilt is detected, the fault information can be immediately transmitted to the power grid center. At the same time, based on the accurate judgment of the tilt direction, the power department can quickly formulate maintenance strategies and rationally allocate resources, avoiding the inefficiency and omissions in traditional inspections. In addition, the device has a compact structure, is easy to install, and is suitable for transformer inspection needs in various scenarios, combining technological advancement and engineering practicality.

[0018] Example: Please refer to Figure 1 , Figure 2 and Figure 3 A transformer tilt detection device includes a transformer body 1. First U-shaped support blocks 2 are connected to the lower two sides of the transformer body 1. Second U-shaped support blocks 3 are connected to the lower two sides of each first U-shaped support block 2. First semi-arc fixing blocks 5 are connected to the two sides of the end of each second U-shaped support block 3 facing the middle part of the transformer body 1. A utility pole 6 is connected to the end of the first semi-arc fixing block 5 facing the middle part of the transformer body 1. Detection components 7 are connected to the grooves at both ends of each first U-shaped support block 2. The two first semi-arc fixing blocks 5 are fixed to the surface of the utility pole 6 by a first fixing nut. Please see Figure 4 and Figure 5 The detection component 7 includes a first connecting rod 701, with a second connecting rod 702 connected to one end of the first connecting rod 701 facing the middle of the transformer body 1. A first fixing bolt 703 passes through the junction of the first connecting rod 701 and the second connecting rod 702. A first lateral tilt detection component 704 is connected to one end of the first connecting rod 701 facing the utility pole 6. Concave connecting blocks 705 are connected to both sides of the end of the first lateral tilt detection component 704 facing the middle of the transformer body 1. A second lateral tilt detection component 706 is connected to one end of the second connecting rod 702 facing the utility pole 6. Convex connecting blocks 705 are connected to both sides of the end of the second lateral tilt detection component 706 facing the middle of the transformer body 1. The first fixing rod 708 passes through the overlapping position of the concave connecting block 705 and the convex connecting block 707. The upper ends of the first lateral tilt detection component 704 and the second lateral tilt detection component 706 facing the middle part of the transformer body 1 are both connected to the vertical tilt detection component 709. Both ends of the first fixing rod 708 are connected to threads, and a fixing nut is connected to the outside of each thread. The end of the first connecting rod 701 facing the second connecting rod 702 has a groove, and the end of the second connecting rod 702 facing the first connecting rod 701 is connected to the second rectangular connecting block. At this time, the first connecting rod 701 and the second connecting rod 702 are fixed together by a fixing bolt passing through them.

[0019] Please see Figure 1 and Figure 2 A first rectangular connecting plate 8 is connected to the gap between the two second U-shaped support blocks 3. A control box 9 is connected to the lower surface of the first rectangular connecting plate 8. An alarm 10 is connected to one end of the control box 9.

[0020] Specifically, when lateral tilt is detected, when the seventh connecting rod 723 contacts the second U-shaped connecting block 715, the second semi-circular fixing block 710 and the third connecting rod 712 will automatically form a stable triangular support to provide reverse support force. Moreover, when tilting vertically, the tilting force causes the upper part of the circular guide rod 729 to coincide with the circular hole 728, generating an upward force on the transformer body 1. Then, the triangular structures at both ends provide reverse support force, dynamically limiting further tilting of the transformer. This effectively reduces the risk of secondary damage such as winding displacement and insulating oil leakage caused by increased tilting, ensuring equipment safety.

[0021] Please see Figure 6 The first lateral tilt detection component 704 includes a second semi-circular fixing block 710, a third semi-circular fixing block 711 connected to one end of the second semi-circular fixing block 710 facing the first connecting rod 701, a third connecting rod 712 connected to one end of the third semi-circular fixing block 711 facing the first connecting rod 701, a circular rotating rod 713 connected to one end of the third connecting rod 712 away from the third semi-circular fixing block 711, and a fourth connecting rod 714 connected to both sides of the end of the third semi-circular fixing block 711 facing the first connecting rod 701. The circular rotating rod 713 is rotatably connected to the third connecting rod 712. The second semi-circular fixing block 710 and the third semi-circular fixing block 711 are fixed together by a second fixing nut.

[0022] Please see Figure 6Each fourth connecting rod 714 has a second U-shaped connecting block 715 connected to the end away from the third semi-circular fixing block 711. Each second U-shaped connecting block 715 has an arc-shaped groove 716 in its inner cavity. Each arc-shaped groove 716 has a second circular rotating rod 717 connected to the end away from the circular rotating rod 713. A rectangular trigger block 718 is connected to the outer surface of each second circular rotating rod 717. A third rectangular connecting block 719 is connected to the lower end of each rectangular trigger block 718. A fifth connecting rod 720 is sleeved on the middle part of the circular rotating rod 713. A sixth connecting rod 721 is connected to the inner cavity of the fifth connecting rod 720. A trigger groove is formed on the upper surface of the third rectangular connecting block 719, and the trigger groove fits into the rectangular trigger block 718. The rectangular trigger block 718 initially aligns with the trigger groove. The three rectangular connecting blocks 719 and 720 are completely overlapped. A rectangular frame is connected to the outside of the third rectangular connecting block 719. An infrared sensor is installed in the inner cavity of the rectangular frame. When the infrared sensor detects that the rectangular trigger block 718 and the trigger groove are not completely overlapped, the surface transformer is tilted laterally. This causes the infrared sensor to send a signal to the control box 9 and activate the alarm 10. The alarm signal in the alarm 10 is transmitted to the power grid center and the power company can accurately determine the location of the transformer tilt. The fifth connecting rod 720 has a second rectangular groove at one end facing the sixth connecting rod 721. The width of the sixth connecting rod 721 matches the second rectangular groove. The ends of the fifth connecting rod 720 and the sixth connecting rod 721 away from the circular rotating rod 713 are both connected to the second U-shaped connecting block 715.

[0023] Please see Figure 6 The second semi-circular fixing block 710, the third semi-circular fixing block 711, the third connecting rod 712, the circular rotating rod 713, the fourth connecting rod 714, the second U-shaped connecting block 715, the fifth connecting rod 720, and the sixth connecting rod 721 together form a stable triangular structure, and the components of the second lateral tilt detection component 706 are the same as those of the first lateral tilt detection component 704.

[0024] Please see Figure 7 and Figure 8 The vertical tilt detection component 709 includes a first rectangular connecting block 725. A T-shaped connecting block 722 is connected to one end of the first rectangular connecting block 725 away from the first U-shaped support block 2. A seventh connecting rod 723 is connected to the lower end of the T-shaped connecting block 722. A second circular rotating block 724 is connected to the lower end of the seventh connecting rod 723. A rectangular sealing block 731 is connected to the outer surface of the seventh connecting rod 723.

[0025] Specifically, through the linkage design of the horizontal and vertical tilt detection components, when the rectangular trigger block 718 and the trigger groove are not completely overlapped, it indicates that the transformer body 1 is tilted horizontally. By detecting whether the gap between the T-shaped connecting block 722 and the seventh connecting rod 723 is closed, if it is closed, it indicates that the transformer body 1 is tilted vertically. This not only detects the tilt status in real time, but also accurately identifies the tilt direction. This feature allows maintenance personnel to quickly deduce vulnerable parts inside the transformer. For example, horizontal tilt may cause damage to the bushing, and vertical tilt may affect the tap changer. This allows for targeted carrying of maintenance spare parts, greatly improving maintenance efficiency and reducing secondary operations caused by insufficient spare parts.

[0026] Please see Figure 7 and Figure 8 The seventh connecting rod 723 has a T-shaped groove 726 at one end facing the T-shaped connecting block 722. A second rectangular connecting plate 727 is connected to the inner cavity of the T-shaped groove 726. The surface of the second rectangular connecting plate 727 has several circular holes 728. A circular guide rod 729 is connected to the inner cavity of each circular hole 728. There is a gap between the T-shaped connecting block 722 and the seventh connecting rod 723 in the initial state. A reset spring 730 is provided on the lower end surface of each circular guide rod 729. The second circular rotating block 724 is connected to the second circular rotating rod 717. The upper end of the reset spring 730 is fixed to the lower end surface of the second rectangular connecting plate 727. A second infrared sensor is connected to the inner cavity of the rectangular sealing block 731. If the second infrared sensor detects that the gap between the T-shaped connecting block 722 and the seventh connecting rod 723 is closed, the surface transformer body 1 will be in a vertical tilt state.

[0027] Specifically, through the intelligent monitoring link of infrared sensor-control box 9-alarm 10, once tilt is detected, the fault information can be immediately transmitted to the power grid center. At the same time, based on the accurate judgment of the tilt direction, the power department can quickly formulate maintenance strategies and rationally allocate resources to avoid the inefficiency and omissions in traditional inspections. In addition, the device has a compact structure, is easy to install, and is suitable for transformer inspection needs in various scenarios, combining technological advancement and engineering practicality.

[0028] The detection method of the transformer tilt detection device includes the following steps: S1. When the transformer body 1 is subjected to earthquakes, foundation settlement, and external impacts, causing it to tilt laterally, a deflection force is generated on the first rectangular connecting block 725. This causes the vertical tilt detection component 709 to rotate around the second circular rotating block 724, which in turn causes the second circular rotating rod 717 to rotate. As the second circular rotating rod 717 rotates, it causes the rectangular trigger block 718 to rotate, resulting in the rectangular trigger block 718 and the trigger groove on the upper surface of the third rectangular connecting block 719 not being completely overlapped. This indicates that the transformer is tilted laterally. When the infrared sensor detects that the rectangular trigger block 718 and the trigger groove are not completely overlapped, the infrared sensor sends a signal to the control box 9, which then activates the alarm 10. The alarm signal in the alarm 10 is transmitted to the power grid center, allowing the power company to accurately determine the location of the transformer tilt. Based on the location of the signal emitted by the infrared sensor, the tilt direction of the transformer body 1 is determined, thereby calculating the probability of damage to the internal components of the transformer. Maintenance personnel are then dispatched to the destination for maintenance. S2. If the transformer body 1 continues to tilt while the maintenance personnel are on their way, when the seventh connecting rod 723 in the vertical tilt detection component 709 contacts both ends of the second U-shaped connecting block 715, the second semi-circular fixing block 710, the third semi-circular fixing block 711, the third connecting rod 712, the circular rotating rod 713, the fourth connecting rod 714, the second U-shaped connecting block 715, the fifth connecting rod 720, and the sixth connecting rod 721 will form a stable triangular structure to fix the transformer body 1 and prevent the transformer body 1 from tilting further. S3. If the transformer body 1 is subjected to earthquake, foundation settlement, or external impact, causing the transformer body 1 to tilt vertically, it will generate a forward or backward pressure. At this time, the T-shaped connecting block 722 in the vertical tilt detection component 709 on the side subjected to pressure will move downward along the T-shaped groove 726, thereby causing the second rectangular connecting plate 727 to move downward along the circular guide rod 729, and then causing the reset spring 730 to retract. When the gap between the T-shaped connecting block 722 and the seventh connecting rod 723 closes, the upper part of the circular guide rod 729 will coincide with the circular hole 728. At this time, the triangular stabilizing structure formed by the detection components 7 at both ends will provide support for the tilting side of the transformer body 1, preventing the transformer body 1 from continuing to tilt. S4. When the second infrared sensor detects that a gap between the T-shaped connecting block 722 and the seventh connecting rod 723 is in a closed state, the second infrared sensor sends a signal to the control box 9, and the control box 9 activates the alarm 10. The alarm signal in the alarm 10 is then transmitted to the power grid center, allowing the power company to accurately determine the location where the transformer is tilting. Based on the location of the signal emitted by the infrared sensor, the tilt direction of the transformer body 1 is determined, thereby calculating the probability of damage to the internal components of the transformer. Maintenance personnel are then dispatched to the destination to carry out maintenance operations until the transformer body 1 is successfully repaired, at which point all operations are completed.

6. The transformer tilt detection device according to claim 5, characterized in that: The vertical tilt detection component (709) includes a first rectangular connecting block (725), with a T-shaped connecting block (722) connected to one end of the first rectangular connecting block (725) away from the first U-shaped support block (2). A seventh connecting rod (723) is connected to the lower end of the T-shaped connecting block (722), and a second circular rotating block (724) is connected to the lower end of the seventh connecting rod (723). A rectangular sealing block (731) is connected to the outer surface of the seventh connecting rod (723), and a second infrared sensor is connected to the inner cavity of the rectangular sealing block (731).

7. The transformer tilt detection device according to claim 6, characterized in that: The seventh connecting rod (723) has a T-shaped groove (726) at one end facing the T-shaped connecting block (722). A second rectangular connecting plate (727) is connected in the inner cavity of the T-shaped groove (726). A number of circular holes (728) are opened on the surface of the second rectangular connecting plate (727). A circular guide rod (729) is connected in the inner cavity of each circular hole (728). There is a gap between the T-shaped connecting block (722) and the seventh connecting rod (723) in the initial state. A reset spring (730) is opened on the lower surface of each circular guide rod (729).

8. A detection method for a transformer tilt detection device, as described in claim 7, characterized in that, Includes the following steps: S1. When the transformer body (1) is subjected to earthquakes, foundation settlement, and external impacts, causing the transformer body (1) to tilt laterally, a deflection force will be generated on the first rectangular connecting block (725), thereby causing the vertical tilt detection component (709) to rotate around the second circular rotating block (724), which in turn causes the second circular rotating rod (717) to rotate. As the second circular rotating rod (717) rotates, it will cause the rectangular trigger block (718) to rotate, so that the trigger groove opened on the upper surface of the rectangular trigger block (718) and the third rectangular connecting block (719) are not completely overlapped. When the transformer is tilted laterally, the infrared sensor detects that the rectangular trigger block (718) and the trigger groove are not completely aligned. This causes the infrared sensor to send a signal to the control box (9) and activate the alarm (10). The alarm signal in the alarm (10) is then transmitted to the power grid center, allowing the power company to accurately determine the location of the transformer tilt. Based on the location of the signal emitted by the infrared sensor, the tilt direction of the transformer body (1) is determined, thereby calculating the probability of damage to the internal components of the transformer. Then, maintenance personnel are dispatched to the destination to carry out maintenance operations. S2. If the transformer body (1) continues to tilt during the arrival of maintenance personnel, when the seventh connecting rod (723) in the vertical tilt detection component (709) contacts both ends of the second U-shaped connecting block (715), the second semi-circular fixing block (710), the third semi-circular fixing block (711), the third connecting rod (712), the circular rotating rod (713), the fourth connecting rod (714), the second U-shaped connecting block (715), the fifth connecting rod (720), and the sixth connecting rod (721) will form a stable triangular structure to fix the transformer body (1) and prevent the transformer body (1) from tilting further. S3. If the transformer body (1) is subjected to earthquake, foundation settlement and external impact factors, causing the transformer body (1) to tilt vertically, it will generate a forward or backward pressure. At this time, the T-shaped connecting block (722) in the vertical tilt detection component (709) on the side subjected to pressure will move downward along the T-shaped groove (726), thereby causing the second rectangular connecting plate (727) to move downward along the circular guide rod (729), and then causing the reset spring (730) to retract. When the gap between the T-shaped connecting block (722) and the seventh connecting rod (723) is closed, the upper part of the circular guide rod (729) will coincide with the circular hole (728). At this time, the triangular stable structure formed in the detection components (7) at both ends will provide support for the tilting side of the transformer body (1) and prevent the transformer body (1) from continuing to tilt. S4. When the second infrared sensor detects that a gap exists between the T-shaped connecting block (722) and the seventh connecting rod (723) is in a closed state, the second infrared sensor sends a signal to the control box (9) and the control box (9) activates the alarm (10), so that the alarm signal in the alarm (10) is transmitted to the power grid center and the power company accurately determines the location where the transformer tilts. Then, based on the location of the signal emitted by the infrared sensor, the tilt direction of the transformer body (1) is determined, thereby calculating the probability that the internal components of the transformer may be damaged, and then dispatching maintenance personnel to the destination to carry out maintenance operations until the transformer body (1) is successfully repaired, and then all operations are completed.
