Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a highly safe outdoor transformer compartment and its self-protection method. Background Technology

[0002] As a core supporting equipment of the power system, outdoor transformer compartments are exposed to complex natural environments for a long time. They need to meet the dual requirements of ventilation and heat dissipation as well as protection against severe weather. The heat dissipation structure of existing outdoor transformer compartments mostly adopts a fixed ventilation gap design. In severe weather such as blizzards, heavy rain, and strong winds, rainwater and debris can easily enter the compartment through the ventilation gaps, causing the insulation of internal components to become damp and short-circuit faults. Strong wind impacts can also cause the heat dissipation plate to deform and the compartment structure to loosen, leading to safety hazards.

[0003] Existing solutions mostly rely on manual inspection to close protective barriers or configure electrically triggered protective structures. However, manual inspections suffer from slow response times and high maintenance costs, making them unsuitable for unattended outdoor scenarios. Electrically controlled structures are prone to sensor failures and circuit faults in high-humidity and dusty environments, resulting in insufficient reliability. Furthermore, they completely lose their protective capabilities when power is off. In addition, closing some protective structures can block ventilation paths, causing a sharp rise in cabin temperature and triggering transformer overload operation failures. It is difficult to achieve a balance between protection and heat dissipation.

[0004] Therefore, it is necessary to provide a highly secure outdoor transformer compartment and a self-protection method to solve the problems mentioned in the background art. Summary of the Invention

[0005] The present invention aims to provide a highly safe outdoor transformer compartment to overcome the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a high-safety outdoor transformer compartment, including an outer compartment, a detection compartment, a triggering mechanism, and a self-protection mechanism. The outer compartment is provided with heat dissipation plates on both sides. The detection compartment is located on the top of the outer compartment. The triggering mechanism is connected to the self-protection mechanism and includes a detection groove and a pressure rod. The detection groove is located in the middle of the detection compartment and is slidably connected to the detection compartment. The upper end of the pressure rod is connected to the detection groove, and the lower end extends into the outer compartment. The self-protection mechanism is located inside the outer cabin and includes a telescopic mechanism and a support plate. The telescopic mechanism is fixed inside the outer cabin, and its telescopic rod is connected to the pressure rod at its telescopic end. There are two support plates, which are symmetrically arranged inside the two heat dissipation plates. Each support plate is connected to the telescopic end of the telescopic mechanism through a transmission component. Under the action of the transmission component, the telescopic end of the telescopic mechanism extends and retracts, causing the support plate to move closer to or away from the heat dissipation plate. During severe weather such as blizzards and rainstorms, the accumulated rain and snow in the detection slot cause the detection slot to activate the telescopic mechanism due to its own weight. Once the triggering mechanism is activated, the telescopic mechanism drives the support plate to move towards the heat dissipation plate through the transmission component, so that the support plate abuts against the inner side of the heat dissipation plate, sealing the ventilation gaps of the heat dissipation plate and supporting and reinforcing the heat dissipation plate.

[0007] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the bottom of the testing tank is provided with a drain outlet, and the drain outlet is provided with a water outlet pipe, which discharges the water from the testing tank to the outside of the testing compartment.

[0008] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the self-protection mechanism also includes an extension rod and a spring. The two ends of the extension rod are fixedly connected to the pressure rod and the telescopic rod of the telescopic mechanism, respectively. The spring is set outside the telescopic rod of the telescopic mechanism, and the two ends of the spring abut against the main body of the telescopic mechanism and the extension rod, respectively.

[0009] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the first transmission component is a linkage structure. The input end of the first transmission component is connected to an adapter block fixed to the outside of the extension rod, and the output end of the first transmission component is provided with a fixed frame. The support plate is located on the fixed frame.

[0010] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the transmission assembly includes connecting rod one, connecting rod two, and connecting rod three. One end of connecting rod three is hinged to the adapter block, and the other end is hinged to the rod body of connecting rod one. Connecting rod one and connecting rod two are arranged in parallel, and the lower ends of connecting rod one and connecting rod two are both hinged to a fixed plate. The upper ends of connecting rod one and connecting rod two are both hinged to a fixed frame. The fixed plate is sleeved on the outside of the extension rod and is fixedly connected to the outer compartment through a support frame.

[0011] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the ventilation gaps on the support plate are staggered from those on the heat dissipation plate. The support plate is a split structure, comprising an upper support plate, a middle support plate, and a lower support plate arranged sequentially from top to bottom. The middle support plate is fixed to the side of the fixing frame near the heat dissipation plate. The upper and lower support plates are respectively located above and below the fixing frame. The upper and lower support plates are staggered from the middle support plate, and the three are automatically combined into a support plate by a pneumatic control component.

[0012] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the start-up control assembly includes cylinder one, cylinder two, cylinder three, a touch plate, and spring two. Cylinder one is fixedly mounted diagonally above the fixed frame, and its telescopic end is connected to the upper support plate. Cylinder two is fixedly mounted diagonally below the fixed frame, and its telescopic end is connected to the lower support plate. Cylinder three is fixed inside the fixed frame, and its telescopic rod end is provided with a touch plate. The telescopic rod of cylinder three passes through the middle support plate and is slidably connected to the middle support plate. The middle support plate has a groove for accommodating the touch plate on the side near the touch plate. The rodless chamber of the piston chamber of cylinder three communicates with the rodless chambers of the piston chambers of cylinder one and cylinder two. Spring two is sleeved on the outside of the telescopic rod of cylinder three, and both ends of spring two abut against the body of cylinder three and the touch plate, respectively.

[0013] Furthermore, the aforementioned high-safety outdoor transformer compartment also includes a second triggering mechanism located on the top of the outer compartment. The second triggering mechanism includes multiple wind-driven triggering components. The detection compartment is fixed above the outer compartment by support columns. The multiple wind-driven triggering components are arranged around the sides of the detection compartment, including a wind vane and a trigger. The wind vane is located above the outer compartment and is slidably connected to the outer compartment. Under the action of wind, the wind vane moves into the detection compartment and triggers the trigger located inside the detection compartment. The trigger is connected to the telescopic mechanism signal of the self-protection mechanism.

[0014] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the wind-triggered component further includes a transmission component two. The transmission component two includes a slide plate one, a slide plate two, a connecting plate one, a connecting plate two, a push rod, and a support base. The slide plate one is fixed to the outer compartment and has a slide groove one. The slide plate two has a slide groove two arranged parallel to the slide groove one. The connecting plate one and the connecting plate two are X-shaped cross-hinged, with the first end of the connecting plate one hinged to the slide plate one and the first end of the connecting plate two hinged to the sliding plate. The second ends of both the connecting plate one and the connecting plate two are hinged to a slider located in the slide groove two and slidably connected to the slide groove two. One end of the sliding plate is inserted into the slide groove one and slidably connected to the slide groove one. The support base is fixed above the outer compartment. The push rod passes through the support base and slidably connected to the support base. One end of the push rod is connected to the sliding plate, and the other end cooperates with the trigger. The wind plate is fixed to the outside of the slide plate two.

[0015] Furthermore, the aforementioned high-safety outdoor transformer compartment also includes a ventilation mechanism, which includes a baffle, a backup fan, and a winding assembly. A ventilation opening is provided on the rear side of the outer compartment, and a switchable baffle is provided on the ventilation opening. The baffle is switched on and off by the winding assembly, which is signal-connected to the telescopic mechanism. A backup fan is provided inside the outer compartment on the inner side of the ventilation opening, and an air outlet is provided on the front side of the outer compartment corresponding to the ventilation opening.

[0016] Furthermore, in the aforementioned high-safety outdoor transformer compartment, the winding assembly includes a winder and a steel wire rope. The upper end of the baffle is rotatably connected to the outer compartment, and one end of the steel wire rope is wound around the winder, while the other end is connected to the lower end of the baffle.

[0017] Preferably, the bottom of the outer cabin is fixed with a riser frame, the outer cabin is equipped with multiple transformers, the inner cavity sidewall of the outer cabin is equipped with a load-bearing plate, and the load-bearing plate is equipped with a power supply.

[0018] This invention also provides a self-protection method for a highly secure outdoor transformer compartment, comprising the following steps: S1. Under normal circumstances, the transformer operates normally, and the self-protection mechanism, triggering mechanism, and triggering mechanism II are all in the initial standby state. The outer compartment is naturally ventilated and cooled through the ventilation gaps of the heat dissipation plates on both sides. S2. When encountering severe weather such as blizzards and rainstorms, the accumulation of rain and snow in the detection tank causes the detection tank to press down due to its own weight, triggering the telescopic mechanism to start. The telescopic rod of the telescopic mechanism moves down, causing the support plate to move towards the heat dissipation plate. The support plate is misaligned to block the ventilation gaps of the heat dissipation plate and abuts against the inside of the heat dissipation plate to support and reinforce it. S3. When encountering strong winds, the wind pushes the wind vane into the testing chamber, triggering the trigger. The trigger sends a signal to the telescopic machine, which starts. The telescopic rod of the telescopic machine moves down, causing the support plate to move towards the heat dissipation plate. The support plate is misaligned to block the ventilation gaps of the heat dissipation plate and abuts against the inside of the heat dissipation plate to support and reinforce it. S4. When the telescopic machine starts, the ventilation mechanism starts simultaneously, the winder starts, the baffle at the lower rear ventilation opening of the outer cabin is opened, and the standby fan inside the outer cabin starts, forming a new heat dissipation air duct with the air outlet on the front of the outer cabin to ensure normal heat dissipation inside the cabin. S5. After the severe weather ends, the rain and snow in the testing tank are discharged through the drain outlet, the wind vane is reset, the telescopic mechanism stops, the support plate is reset to release the blockage of the ventilation holes of the heat sink, and the equipment returns to its initial natural ventilation state.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention achieves comprehensive protection and reinforcement through a dual passive trigger linkage structure of rain and snow weight and wind force, without relying on electronic control sensors and external power supply, realizing automatic identification and protection against severe weather, completely avoiding the problem of easy failure of electronic control components in outdoor high humidity and dusty environments, greatly improving the operational reliability of the protection system, adapting to outdoor unattended operation scenarios, eliminating the need for regular manual inspection and operation, and reducing equipment maintenance costs.

[0020] The reinforcement mechanism of this invention adopts a split support plate for protection and reinforcement. When split, it avoids the support plate being integrated and affecting the air circulation inside the compartment. In severe weather, the support plate is integrated into one piece. The rigid structure after the plate is integrated not only seals and protects the ventilation gap, but also reinforces the heat dissipation plate and enhances its impact resistance. It realizes the integrated function of sealing and reinforcement, effectively solving the defects of existing protective structures that can only provide single protection and cannot reinforce, thus improving the overall safety of the transformer compartment.

[0021] The ventilation mechanism of this invention achieves a balance between protection and heat dissipation, avoiding the problem of increased temperature inside the chamber after the heat dissipation plate is blocked, ensuring that the transformer can maintain stable heat dissipation efficiency under severe weather conditions, and eliminating overload operation failure.

[0024] 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. Example 1

[0025] like Figure 1-5 As shown, a high-safety outdoor transformer compartment includes an outer compartment 1, a detection compartment 2, a triggering mechanism 3, and a self-protection mechanism 4. Heat dissipation plates 11 are provided on both sides of the outer compartment 1. The detection compartment 2 is located on the top of the outer compartment 1. The triggering mechanism 3 is connected to the self-protection mechanism 4 and includes a detection groove 31 and a pressure rod 32. The detection groove 31 is located in the middle of the detection compartment 2 and is slidably connected to the detection compartment 2. The upper end of the pressure rod 32 is connected to the detection groove 31, and the lower end extends into the outer compartment 1. The self-protection mechanism 4 is located inside the outer cabin 1 and includes a telescopic mechanism 41 and a support plate 42. The telescopic mechanism 41 is fixed inside the outer cabin 1, and its telescopic rod at the telescopic end is connected to the pressure rod 32. There are two support plates 42, which are symmetrically arranged on the inner side of the two heat dissipation plates 11. Each support plate 42 is connected to the telescopic end of the telescopic mechanism 41 through a transmission component 43. Under the action of the transmission component 43, the telescopic end of the telescopic mechanism 41 extends and retracts, causing the support plate 42 to move closer to or away from the heat dissipation plate 11.

[0026] like Figure 2-4 As shown, in order to reset when the water in the detection tank is drained, the self-protection mechanism 4 also includes an extension rod 44 and a spring 45. The two ends of the extension rod 44 are fixedly connected to the pressure rod 32 and the telescopic rod of the telescopic machine 41, respectively. The spring 45 is sleeved on the outside of the telescopic rod of the telescopic machine 41, and the two ends of the spring 45 abut against the main body of the telescopic machine 41 and the extension rod 44, respectively.

[0027] Specifically, under normal weather conditions, the transformer operates normally, the telescopic mechanism 41 is in a naturally extended state, the support plate 42 maintains a distance from the heat dissipation plate 11, and the transformer compartment 1 is naturally ventilated and cooled through the ventilation gaps of the heat dissipation plate 11.

[0028] When encountering severe weather such as blizzards and rainstorms, the accumulated rain and snow in the detection slot 31 cause the detection slot 31 to move downward due to its own weight, triggering the telescopic end of the telescopic mechanism 41. The triggering mechanism 4 is triggered, and the telescopic mechanism 41 moves downward through the transmission component 43, causing the support plate 42 to move towards the heat dissipation plate 11, so that the support plate 42 abuts against the inside of the heat dissipation plate 11, sealing the ventilation gaps of the heat dissipation plate 11 and supporting and reinforcing the heat dissipation plate 11.

[0029] In addition, such as Figure 1 As shown, the bottom of the testing tank 31 is provided with a drain outlet 311, and the drain outlet 311 is equipped with a water outlet pipe, which drains the water from the testing tank 31 to the outside of the testing chamber 1. The drain outlet 311 is a normal hole. When there is water in the testing tank 31, the water will be discharged by gravity, but the discharge volume is limited. The drain outlet not only prevents the support plate from blocking the ventilation gap of the heat dissipation plate for a long time after prolonged water accumulation following severe weather, but also prevents the self-protection mechanism from being triggered to reinforce itself when there is excessive water accumulation due to prolonged light rain. This avoids self-protection blocking when there is no severe weather, thus ensuring effective heat dissipation of the transformer compartment.

[0030] When the severe weather ends, the water in the testing tank 31 is slowly discharged through the drain outlet 311, reducing the weight. The spring 45 rebounds, causing the pressure rod 32 and the telescopic mechanism 41 to reset, thereby resetting the support plate 42, resolving the blockage of the heat dissipation plate, and restoring the equipment to a state of natural ventilation of the heat dissipation plate.

[0031] In the above structure, such as Figure 2-4 As shown, the transmission component 43 is a linkage transmission structure. The input end of the transmission component 43 is connected to the adapter block 46 fixed outside the extension rod 44. The output end of the transmission component 43 is provided with a fixed frame 47, and the support plate 42 is provided on the fixed frame 47.

[0032] Specifically, the transmission assembly 43 includes a first connecting rod 431, a second connecting rod 432, and a third connecting rod 433. One end of the third connecting rod 433 is hinged to the adapter block 46, and the other end is hinged to the rod body of the first connecting rod 431. The first connecting rod 431 and the second connecting rod 432 are arranged in parallel, and the lower ends of the first connecting rod 431 and the second connecting rod 432 are both hinged to the fixed plate 434. The upper ends of the first connecting rod 431 and the second connecting rod 432 are both hinged to the fixed frame 47. The fixed plate 434 is sleeved on the outside of the extension rod 44 and is fixedly connected to the outer cabin 1 through the support frame 435.

[0033] When the extension rod 44 moves down, the adapter block 46 fixed on the extension rod 44 moves down, causing the connecting rod 3 433 to rotate in the direction of the heat sink 11, which in turn causes the connecting rod 1 431 and the connecting rod 2 432 to rotate synchronously. The connecting rod 1 431, the connecting rod 2 432, the fixed plate 434, and the fixed frame 47 form a parallel four-bar linkage structure. During the rotation, the fixed frame 47 always maintains a horizontal posture and moves smoothly in the direction of the heat sink 11, ensuring that the support plate and the heat sink 11 are precisely fitted. When the telescopic machine 41 resets, the extension rod 44 rises, the adapter block 46 moves upward, and the connecting rod 3 433 pulls the connecting rod 1 431 and the connecting rod 2 432 to rotate in the opposite direction, driving the fixed frame 47 to reset smoothly.

[0034] The aforementioned linkage structure enables stable horizontal displacement of the fixed frame, avoiding misalignment and jamming between the support plate and the heat sink plate during displacement. This ensures the accuracy and reliability of the sealing action. Furthermore, the linkage transmission structure is rigid, has good vibration resistance, is suitable for the long-term operating environment of outdoor transformer compartments, and has a long service life.

[0035] like Figure 3-4 As shown, the ventilation gaps on the support plate 42 are staggered from the ventilation gaps on the heat sink 11. The support plate 42 is a split structure, including an upper support plate 421, a middle support plate 422, and a lower support plate 423 arranged sequentially from top to bottom. The middle support plate 422 is fixed to the side of the fixing frame 47 near the heat sink 11. The upper support plate 421 and the lower support plate 423 are respectively located above and below the fixing frame 47. The upper support plate 421 and the lower support plate 423 are staggered from the middle support plate 423, and the three are automatically combined into the support plate 42 by the pneumatic control component 48.

[0036] The start control assembly 48 includes cylinder 481, cylinder 482, cylinder 483, a touch plate 484, and spring 485. Cylinder 481 is fixed to the upper part of the fixed frame 47, and its extension end is connected to the upper support plate 421. Cylinder 482 is fixed to the lower part of the fixed frame 47, and its extension end is connected to the lower support plate 423. Cylinder 483 is fixed inside the fixed frame 47, and its extension rod end is equipped with a touch plate 484. The telescopic rod of cylinder 3 483 passes through the middle support plate 422 and is slidably connected to the middle support plate 422. The middle support plate 422 has a groove for accommodating the touch plate 484 on the side near the touch plate 484. The rodless chamber of the piston chamber of cylinder 3 483 is connected to the rodless chamber of the piston chamber of cylinder 1 481 and cylinder 2 482. Spring 2 485 is sleeved on the outside of the telescopic rod of cylinder 3 483, and the two ends of spring 2 485 abut against the main body of cylinder 3 483 and the touch plate 484, respectively.

[0037] Specifically, during the movement of the fixing frame 47 toward the heat sink 11, the contact plate 484 first abuts against the inner wall of the heat sink 11. As the fixing frame 47 continues to move, the heat sink 11 exerts reverse pressure on the contact plate 484, pushing the telescopic rod of cylinder three 483 inward to compress. Spring two 485 is compressed and stores energy. The gas in the rodless chamber of cylinder three 483 is synchronously transported through the air pipe to the rodless chambers of cylinder one 481 and cylinder two 482, driving the telescopic rods of these two cylinders synchronously. The upper support plate 421 extends upwards and the lower support plate 423 extends downwards, precisely fitting together with the middle support plate 422. This combined plate acts as a support, with the touch plate 484 embedded in a groove on the middle support plate 422 without protruding. After the plates are joined, the ventilation gaps on the upper, middle, and lower support plates 421, 422, and 423 are offset from the ventilation gaps on the heat sink 11, forming a seal and providing internal support for the heat sink 11. During resetting, the spring 485 rebounds, pushing the extension rod of the cylinder 483 to extend, causing gas to flow back. The extension rods of the cylinders 481 and 482 retract, resetting the upper and lower support plates 421 and 423, releasing the combined plate state. The spring 485 ensures a tight fit between the touch plate and the heat sink, provides resetting power, simplifies the structural design, and improves operational stability.

[0038] As can be seen from the above, under normal circumstances, the support plate is a split structure, which can avoid the support plate being integrated and affecting the air circulation inside the cabin. In severe weather, the support plate is integrated into one piece. The rigid structure after the plate is integrated not only seals and protects the ventilation gap, but also reinforces the heat dissipation plate and enhances the impact resistance of the heat dissipation plate. It realizes the integrated function of sealing and reinforcement, and solves the defect of the single function of the existing protective structure.

[0039] The triggering mechanism of this invention can automatically activate the self-protection mechanism during severe weather conditions such as blizzards and rainstorms. It avoids the problem of easy failure of the electronic control system in outdoor environments by triggering through a purely mechanical linkage structure. It can also achieve automatic reset of the self-protection mechanism when the weather returns to normal, without manual intervention, which greatly improves the operational reliability and maintenance convenience of the equipment and is perfectly adapted to outdoor unattended scenarios.

[0040] like Figure 2-3 As shown, the bottom of the outer cabin 1 is equipped with a riser 14, which raises the bottom of the outer cabin 1 to prevent the bottom of the cabin from being soaked by ground water after heavy rain, and further improves the cabin's moisture-proof and protective capabilities.

[0041] Multiple transformers 15 are installed inside the outer compartment 1. A load-bearing plate 17 is installed on the inner wall of the outer compartment 1, and a power supply unit 16 is installed on the load-bearing plate 17. The load-bearing plate 17 provides stable installation support for the power supply unit 16, and the power supply unit 17 provides emergency power to the equipment inside the compartment, ensuring that the core protection function can still be realized in the event of an external power failure, improving the emergency operation capability of the equipment, avoiding protection failure caused by power failure, and further enhancing the operational reliability of the equipment. Example 2

[0042] Based on the structure of Example 1, such as Figure 2 and Figure 5 As shown, the aforementioned high-safety outdoor transformer compartment also includes a triggering mechanism 5 located on the top of the outer compartment 1. Triggering mechanism 5 is a wind-driven triggering mechanism, comprising multiple wind-driven triggering components. The detection compartment 2 is fixed above the outer compartment 1 by support columns 21. Multiple wind-driven triggering components are arranged around the sides of the detection compartment 2, including a wind vane 51, a trigger 52, and a transmission component 2. The wind vane 51 is located above the outer compartment 1 and is slidably connected to it. Furthermore, the wind vane 51 also seals the sides of the detection compartment. The input end of the transmission component 2 is connected to the wind vane 51, and the output end of the transmission component 2 is movably connected to the trigger 52. Under wind force, the wind vane 51 moves into the detection compartment 2, triggering the trigger 52 located inside the detection compartment 2. The trigger 52 is signal-connected to the telescopic mechanism 41 of the self-protection mechanism. When the trigger 52 of any wind-driven triggering component is triggered, the self-protection mechanism will activate in conjunction to seal and reinforce the heat sink.

[0043] In this embodiment, the trigger 52 is a waterproof switch with a simple structure that is not affected by rain or snow. The trigger end of the trigger is equipped with an elastic element, which can drive the wind vane to reset when the wind force returns to normal.

[0044] In the above structure, as shown in the figure Figure 5 As shown, the transmission assembly 2 includes a first slide plate 53, a second slide plate 54, a first connecting plate 55, a second connecting plate 56, a push rod 57, and a support base 58. The first slide plate 53 is fixed to the outer compartment 1 and has a first slide groove. The second slide plate 54 has a second slide groove that is parallel to the first slide groove. The first connecting plate 55 and the second connecting plate 56 are X-shaped cross hinges, and the first end of the first connecting plate 55 is hinged to the first slide plate 53, and the first end of the second connecting plate 56 is hinged to the slide plate 59. Next, the second end of connecting plate 1 55 and the second end of connecting plate 2 56 are both hinged to the slider located in the slide groove 2 and slidably connected to the slide groove 2. One end of the slide plate 59 is inserted into the slide groove 1 and slidably connected to the slide groove 1. The support seat 58 is fixed above the outer cabin 1. The push rod 57 passes through the support seat 58 and slidably connected to the support seat 58. One end of the push rod 57 is connected to the slide plate 59, and the other end cooperates with the trigger 52. The wind plate 51 is fixed on the outside of the slide groove plate 2 54.

[0045] When the wind vane is displaced inward by wind pressure, it drives the second sliding plate 54 to move inward synchronously. The second sliding plate 54 drives the first connecting plate 55 and the second connecting plate 56, which are connected in an X-shape, to rotate outward. The first end of the second connecting plate 56 pushes the slide plate 59 to slide outward along the first sliding groove. The slide plate 59 drives the push rod 57 to extend outward. The end of the push rod 57 abuts against the trigger end of the trigger 310 and pushes it to retract, completing the triggering action. After the wind disappears, the thrust of the push rod 57 decreases, and the elastic element at the trigger end of the trigger pushes the push rod 47 to reset, driving the first connecting plate 55 and the second connecting plate 56 to rotate inward, and the wind vane resets. Through the X-shaped cross-hinged linkage structure, the lateral displacement of the wind vane is converted into the linear displacement of the push rod. It has high transmission efficiency and high trigger sensitivity, and can accurately capture strong winds of different intensities. The cooperation between the sliding groove, the slider, and the slide plate ensures the smoothness of the displacement process and avoids jamming failure. At the same time, the structure is simple and rigid, and it is suitable for the vibration environment of long-term outdoor operation.

[0046] In this embodiment, three sets of wind-triggered components are provided, located on the three sides of the detection chamber, to capture strong winds from different directions. When a strong wind acts on the wind vane 51, any wind vane 51 is displaced inward by the wind pressure, causing the inner transmission component 2 to move. The push rod 57 pushes the trigger end of the trigger 52 to retract inward, triggering the trigger 52 to send a signal to start the telescopic mechanism 41 to perform the reinforcement and sealing action. After the wind weakens, the push rod 57 reduces its thrust, and the elastic element at the trigger end of the trigger pushes the push rod 47 to reset, the wind vane 51 resets, and the trigger 52 de-triggers.

[0047] By designing multiple sets of wind-triggered components, the system achieves accurate capture of strong winds from multiple directions, avoids the trigger blind spots present in a single wind vane, improves the comprehensiveness and reliability of wind-triggered systems, and further enhances the system's anti-interference capability and operational stability.

[0048] The triggering mechanism of this invention can automatically activate the self-protection mechanism in strong winds and severe weather. It is triggered by a mechanical linkage structure and a trigger, which is not affected by rain or snow. It also avoids the problem of easy failure of the electrical control system in outdoor environments. When the weather returns to normal, the self-protection mechanism can be automatically reset without manual intervention, which greatly improves the reliability and ease of maintenance of the equipment and is perfectly adapted to outdoor unattended scenarios.

[0049] In addition, such as Figure 1-2As shown, the aforementioned high-safety outdoor transformer compartment also includes a ventilation mechanism 6. The ventilation mechanism 6 includes a baffle 61, a backup fan 62, and a winding assembly. A ventilation opening 12 is provided on the rear side of the outer compartment 1. The ventilation opening 12 is equipped with a switchable baffle 61. The baffle 61 is switched on and off by the winding assembly. The winding assembly is signal-connected to the telescopic machine 41. A backup fan 62 located inside the outer compartment 1 is provided inside the ventilation opening 12. A filter screen is also provided inside the ventilation opening 12. An air outlet 13 corresponding to the ventilation opening 12 is provided on the front side of the outer compartment 1.

[0050] The winding assembly includes a winder 63 and a wire rope. The upper end of the baffle 61 is rotatably connected to the outer cabin 1. One end of the wire rope is wound around the winder 63, and the other end is connected to the lower end of the baffle 61.

[0051] The winding unit 63 is linked to the telescopic conveyor 41. When the telescopic conveyor 41 is triggered to start, the winding assembly is also triggered simultaneously. The winding unit 63 winds up the wire rope, pulling the baffle 61 to rotate a small angle, opening the vent 12, and starting the standby fan 62. A new heat dissipation channel is formed between the vent 12 and the air outlet 13. Specifically, after the vent 12 is opened, outside air is filtered through the filter screen inside the vent and sent into the cabin. Hot air inside the cabin is discharged through the front air outlet 13, forming a stable forced heat dissipation air duct. When the telescopic conveyor stops, the winding assembly also resets synchronously, closing the baffle, closing the vent, stopping the standby fan, closing the new heat dissipation channel, and restoring the transformer cabin to its initial state of natural heat dissipation from the heat sink.

[0052] The coordinated design of the ventilation and reinforcement mechanisms achieves a balance between protection and heat dissipation, preventing the temperature rise inside the chamber after the heat sink is blocked. This ensures that the transformer maintains stable heat dissipation efficiency even in harsh weather conditions and eliminates overload operation failures. The vent filters effectively filter dust and debris, further enhancing the chamber's protection level. The forced airflow mode of the standby fan provides high heat dissipation efficiency and is suitable for the transformer's high-load operating conditions.

[0053] The present invention also provides a self-protection method for a high-safety outdoor transformer compartment, which is used in the aforementioned high-safety outdoor transformer compartment, comprising the following steps: S1. Under normal circumstances, the transformer operates normally, and the self-protection mechanism 4, trigger mechanism one 3, and trigger mechanism two 5 are all in the initial standby state. The outer compartment 1 is naturally ventilated and cooled through the ventilation gaps of the heat dissipation plates 11 on both sides. S2. When encountering severe weather such as blizzards and rainstorms, the accumulation of rain and snow in the detection slot 31 causes the detection slot 31 to press down due to its own weight, triggering the telescopic mechanism 41 to start. The telescopic rod of the telescopic mechanism moves down, causing the support plate 42 to move towards the heat dissipation plate 11. The support plate 42 is misaligned to block the ventilation gap of the heat dissipation plate 11 and abuts against the inner side of the heat dissipation plate 11 to support and reinforce the heat dissipation plate 11. S3. When encountering strong winds, the wind pushes the wind vane 51 to move into the detection chamber 2, triggering the trigger 52. The trigger 52 sends a signal to the telescopic machine 41, which starts. The telescopic rod of the telescopic machine moves down, causing the support plate 42 to move towards the heat dissipation plate 11. The support plate 42 is misaligned to block the ventilation gap of the heat dissipation plate 11 and abuts against the inner side of the heat dissipation plate 11 to support and reinforce it. S4. When the telescopic machine 41 starts, the ventilation mechanism starts simultaneously, the winder starts, the baffle at the lower rear ventilation opening of the outer cabin is opened, and the standby fan in the outer cabin starts, forming a new heat dissipation air duct with the air outlet on the front of the outer cabin to ensure normal heat dissipation inside the cabin. S5. After the severe weather ends, the rain and snow in the detection tank 31 are discharged through the drain outlet, the wind plate 51 is reset, the telescopic machine 41 stops, the support plate 42 is reset to release the blockage of the ventilation gap of the heat dissipation plate 11, and at the same time, the heat dissipation air duct at the ventilation opening is closed, and the equipment is restored to the initial natural ventilation state.

[0054] The above method achieves fully automated operation of the "identification-reinforcement-heat dissipation-reset" process under severe weather conditions through mechanical linkage triggering logic, without the need for manual intervention. It not only solves the problem of delayed response of existing manual inspections, but also avoids the reliability defects of electrical control systems. The rain and snow triggering modes are independent of each other and complement each other, achieving comprehensive protection against severe weather. The linkage design of reinforcement and heat dissipation ensures the stable operation of the transformer during the protection process and avoids temperature rise faults caused by single protection.
