Description

Technical Field

[0001] This invention relates to the technical field of transformer compartments, and more particularly to an energy storage transformer compartment with adaptive protection function and its protection method. Background Technology

[0002] The energy storage transformer compartment is a core supporting equipment for outdoor energy storage power stations. It is mainly used to house and protect the energy storage transformer body, providing a closed and stable operating environment for the transformer. It is also equipped with ventilation, heat dissipation, and dust protection structures to ensure the long-term stable operation of the transformer in outdoor environments. It is currently widely used in various energy storage power station projects on the grid side, new energy generation side, and user side.

[0003] Existing outdoor energy storage transformer compartments have the following shortcomings in actual use: The ventilation and dust prevention structure of existing transformer compartments mostly adopts fixed dust filters. When operating outdoors for a long time, the filters are easily clogged by dust, willow catkins, flying insects and other debris, which directly leads to a decrease in the ventilation volume of the compartment and a continuous increase in the internal temperature, seriously affecting the operating efficiency and service life of the transformer. The existing solution requires manual periodic inspection and disassembly and replacement of filters, which not only has high operation and maintenance costs, but also cannot achieve real-time detection and adaptive replacement of filter clogging status, making it extremely unsuitable for unattended outdoor energy storage power station scenarios.

[0004] In most existing transformer compartments, the transformer body is simply fixed directly to the inside of the compartment with bolts. The continuous mechanical vibration generated by the long-term operation of the transformer can easily cause the mounting bolts to loosen and the transformer body to shift, which in turn can lead to major safety hazards such as poor electrical connections and insulation wear. Existing solutions can only complete the tightening operation through manual shutdown inspection, and cannot achieve real-time detection of the transformer's loose state and adaptive secondary tightening, making it difficult to guarantee the safety and stability of equipment operation.

[0005] Therefore, it is necessary to provide an energy storage transformer compartment with adaptive protection function and its protection method to solve the problems of filter replacement and equipment maintenance mentioned in the background art. Summary of the Invention

[0035] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, through the purely mechanical linkage of the blockage detection component, transmission component, and dust filter replacement component, uses changes in air pressure within the transformer compartment as a trigger source to achieve real-time detection of the blockage status of the dust filter in the exhaust duct and automatic replacement of the dust filter. This avoids the problem of easy failure of electrical control components in outdoor high-humidity and dusty environments, eliminates the need for regular manual inspection and replacement, significantly reduces equipment maintenance costs, ensures that the transformer compartment maintains stable ventilation and heat dissipation efficiency, avoids temperature rise faults in the compartment caused by dust filter blockage, and improves the long-term reliability of the equipment. Through the coordinated operation of the ratchet winding assembly and vibration detection assembly, and with the help of the fiber rod and detection ball linked by the pull wire, abnormal vibration of the transformer body can be detected in real time. When the transformer vibrates excessively due to loose mounting bolts, the drive motor can be automatically triggered to wind up the steel cable and perform adaptive secondary tightening of the transformer body. At the same time, the one-way locking structure of the ratchet and buckle ensures that the tightening will not loosen. This effectively solves the problems of installation loosening and equipment displacement caused by long-term transformer vibration, greatly improves the safety and stability of transformer operation, and is perfectly adapted to the unattended operation scenario of outdoor energy storage power stations.

[0053] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0054] Please see Figure 1-7This invention provides a technical solution: an energy storage transformer compartment with adaptive protection function and its protection method, comprising a transformer compartment 1, a heat sink 2 fixedly installed on the outer wall of the transformer compartment 1, a door 11 hinged to the side wall of the transformer compartment 1, an air inlet 7 fixedly installed on the top of the transformer compartment 1, an air outlet 340 fixedly connected to the bottom air outlet of the transformer compartment 1, and a quality inspection chamber 3 fixedly installed at the bottom of the transformer compartment 1. The quality inspection chamber 3 is equipped with a blockage detection component, a transmission component, and a dustproof screen replacement component. The blockage detection component is connected to the inner cavity of the air outlet 340 and is used to detect the blockage status of the dustproof screen inside the air outlet 340. The input end of the transmission component is driven to the blockage detection component, and the output end of the transmission component is driven to the dustproof screen replacement component. When the blockage detection component is triggered, the transmission component drives the dustproof screen replacement component to automatically replace the dustproof screen at the air outlet 340.

[0055] Specifically, during normal operation of the transformer, the air inlet 7 continuously supplies fresh air into the transformer compartment 1, while the hot air inside the compartment is discharged outward through the air outlet duct 340. This, together with the heat sink 2 on the outer wall, forms a complete heat dissipation process. When the dust filter inside the air outlet duct 340 becomes clogged due to long-term use, the air outlet efficiency of the air outlet duct 340 decreases, and the air pressure inside the transformer compartment 1 continues to rise. The high-pressure airflow enters the blockage detection component, triggering the blockage detection component to complete the locking action. At the same time, it drives the transmission component to operate synchronously. The transmission component converts the mechanical energy generated by the change in air pressure into linear displacement, driving the dust filter replacement component to move towards the air outlet duct 340, completing the disassembly of the old dust filter and the automatic replacement of the new dust filter. The entire process requires no manual intervention, achieving adaptive protection for ventilation and dust prevention in the transformer compartment 1.

[0056] Based on the above embodiments, a purely mechanical linkage structure triggered by air pressure changes enables automatic detection and replacement of the dust filter blockage. This eliminates the need for electronic components such as electrical sensors and controllers, avoiding the problems of easy failure and short lifespan of electrical components in outdoor high-humidity and dusty environments. This significantly improves the operational reliability of the ventilation system in transformer compartment 1. At the same time, it eliminates the need for regular manual inspection and replacement of the dust filter, reducing equipment maintenance costs and ensuring that the interior of transformer compartment 1 maintains stable ventilation and heat dissipation efficiency. This also prevents transformer malfunctions caused by excessively high temperatures inside the compartment due to dust filter blockage.

[0057] The blockage detection assembly includes a first detection cylinder 310, a first detection piston 311, a first crankshaft 313, a second crankshaft 314, a second detection cylinder 317, and a trigger 318. The first detection cylinder 310 is connected to the inner cavity of the air outlet pipe 340. The first detection piston 311 is slidably and sealed within the inner cavity of the first detection cylinder 310. The first crankshaft 313 is rotatably mounted on the inner wall of the quality inspection chamber 3. The upper end of the first detection piston 311 is connected to the first crankshaft 313 via a first connecting rod 312. The second detection cylinder 317 is fixedly mounted on the inner wall of the quality inspection chamber 3, and the second detection piston 314 is slidably and sealed within the inner cavity of the second detection cylinder 317. 16. The second crankshaft 314 is coaxially and fixedly connected to the first crankshaft 313. The second crankshaft 314 is connected to the second detection piston 316 via the second connecting rod 315. The trigger 318 is fixedly installed on the top of the second detection cylinder 317. When the second detection piston 316 slides upward to the limit position, the trigger 318 can be triggered to lock. A first spring 319 is provided between the top of the inner cavity of the second detection piston 316 and the second detection cylinder 317. The output end of the trigger 318 can be extended and locked. After the trigger 318 is unlocked, the first spring 319 rebounds and drives the second detection piston 316 and the first detection piston 311 to return to the initial position.

[0058] Specifically, when the air pressure inside the air outlet duct 340 increases due to dust filter blockage, the high-pressure airflow enters the inner cavity of the first detection cylinder 310, pushing the first detection piston 311 upwards to slide along the inner wall of the cylinder. The first detection piston 311 drives the first crankshaft 313 to rotate around its axis via the first connecting rod 312. The first crankshaft 313 synchronously drives the coaxial second crankshaft 314 to rotate. The second crankshaft 314 drives the second detection piston 316 to slide upwards along the second detection cylinder 317 via the second connecting rod 315. When the second detection piston 316 slides upwards to its limit position, the output end of the trigger 318 is locked, and the first spring 319 is compressed to put it in a stored state. When the trigger 318 is unlocked, the first spring 319 releases its elastic force and pushes the second detection piston 316 downwards to reset. Through the reverse transmission between the connecting rod and the crankshaft, the first detection piston 311 is driven back to its initial position, completing the reset of the entire detection triggering process.

[0059] Based on the above embodiments, the linear displacement of air pressure change is converted into rotational motion through the linkage structure of double cylinder and double crankshaft connecting rod, and then synchronously converted into triggering action, realizing the detection of dust screen blockage. The triggering is stable and unaffected by the temperature and humidity of the external environment. At the same time, the automatic reset of the structure is realized through the first spring 319, eliminating the need for an additional reset drive structure, simplifying the overall design, and improving the operational stability and service life of the detection triggering structure.

[0060] The transmission assembly includes a first pulley 321, a second pulley 324, a threaded rod 330, and a slider 332. The first pulley 321 is rotatably mounted on the inner wall of the quality inspection chamber 3 via a first support frame 320. The first pulley 321 is coaxially and fixedly connected to the second crankshaft 314. The second pulley 324 is rotatably mounted on the inner wall of the quality inspection chamber 3 via a second support frame 323. The first pulley 321 and the second pulley 324 are connected by a belt 322. The threaded rod 330 is rotatably mounted on the inner wall of the quality inspection chamber 3. The second pulley 324 is connected to the threaded rod 330 via a gear reversing mechanism. The transmission connection includes a slider 332 and a threaded rod 330 in a threaded engagement connection. A slide rod 331 is fixedly installed on the inner wall of the quality inspection chamber 3. The slider 332 and the slide rod 331 are in sliding engagement. The gear reversing mechanism includes a first helical gear 325, a transition helical gear 326, and a second helical gear 327. The first helical gear 325 is coaxially and fixedly connected to the second pulley 324. The second helical gear 327 is coaxially and fixedly connected to the threaded rod 330. The transition helical gear 326 is rotatably mounted on the second support frame 323. The first helical gear 325 and the second helical gear 327 are driven by meshing with the transition helical gear 326.

[0061] Specifically, when the second crankshaft 314 rotates, it synchronously drives the first pulley 321 to rotate. The first pulley 321 drives the second pulley 324 to rotate synchronously via the belt 322. The second pulley 324 drives the coaxial first helical gear 325 to rotate. The first helical gear 325 drives the second helical gear 327 to rotate in reverse direction via the adapter helical gear 326. The second helical gear 327 synchronously drives the threaded rod 330 to rotate around its axis. The threaded rod 330 drives the slider 332 to make linear displacement along the slide rod 331 through thread engagement, converting the rotational motion into stable linear displacement, providing stable driving power for the dust screen replacement component.

[0062] Based on the above embodiments, the rotational motion of the crankshaft is precisely converted into the linear displacement of the slider 332 through the cooperation of the belt 322 transmission and the helical gear reversing mechanism, which can meet the stroke requirements for replacing the dust screen. At the same time, the transmission wheel is supported and fixed by the first support frame 320 and the second support frame 323 respectively, avoiding structural shaking during transmission and ensuring the stability and accuracy of power transmission, which is suitable for the long-term vibration operating environment in the transformer compartment 1.

[0063] The dust filter replacement assembly includes a retractor 333, a claw 335, a fixed track 342, a fixed bracket 347, and a cylinder 341. The retractor 333 is fixedly installed on one side of the slider 332. The output end of the retractor 333 is fixedly connected to the claw 335, which is used to grip the second dust filter 344 to be replaced. A second spring 334 is sleeved on the outside of the output end of the retractor 333. The two ends of the second spring 334 abut against and limit the movement of the retractor 333 body and the claw 335, respectively. The fixed track 342 is fixedly installed on the outer wall of the air outlet duct 340. The upper end of the claw 335 slides in cooperation with the fixed track 342. The claw 335 is in a locked state before the trigger 318 is triggered. After the claw 335 is unlocked... The second spring 334 rebounds, causing the sleeve 335 and the second dustproof net 344 to move to the installation position of the air outlet duct 340. The fixed bracket 347 is rotatably installed below the fixed track 342. The fixed bracket 347 can rotate inward to engage and clamp the first dustproof net 345 inside the air outlet duct 340. The cylinder 341 is fixedly installed on the outer wall of the air outlet duct 340. A fixing ring 343 is fixedly connected to the end of the cylinder 341 rod. A third spring 346 is sleeved on the outside of the cylinder 341 rod. The two ends of the third spring 346 abut against and limit the cylinder 341 body and the fixing ring 343 respectively. The fixing ring 343 is arranged opposite to the end of the air outlet duct 340 and is used to clamp and fix the dustproof net at the end of the air outlet duct 340.

[0064] Specifically, when slider 332 moves towards air outlet 340, it drives shrinker 333 and claw 335 to move synchronously. At this time, claw 335 is locked and cannot slide along fixed track 342. The output end of shrinker 333 is compressed inward, and at the same time, the second spring 334 is compressed to put it into a stored state. When the dust screen replacement process is started, cylinder 341 first releases the force, and third spring 346 rebounds, causing fixed ring 343 to extend outward, releasing the clamping and fixing of the first dust screen 345. Then the fixed bracket... 347 rotates clockwise to release the fastener, and the first dustproof net 345 falls off naturally after losing its fixation. At the same time, the claw 335 is unlocked, and the second spring 334 releases its elasticity to push the claw 335 to slide along the fixed track 342, pushing the gripped second dustproof net 344 to the installation position of the air outlet duct 340. Then, the cylinder 341 starts to retract the air rod, driving the fixing ring 343 to move inward to clamp and fix the second dustproof net 344. The fixing bracket 347 rotates in the opposite direction to fasten, supporting the second dustproof net 344 to complete the final fixation.

[0065] Based on the above embodiments, the pre-movement of the slider 332 enables the second spring 334 to store force, and the unlocking and rebound of the sleeve 335 enables the precise pushing of the dustproof net. The entire process is synchronized with the triggering action of the blockage detection component, without the need for an additional independent drive structure. This achieves full automation of the dustproof net disassembly, pushing, and fixing process. At the same time, the double clamping and fixing of the fixing ring 343 and the fixing bracket 347 ensures the sealing and stability of the dustproof net after installation, avoiding problems such as air leakage and falling off, and greatly improving the efficiency and reliability of dustproof net replacement.

[0066] The transformer body 4 is fixedly installed in the inner cavity of the transformer compartment 1 by screws 410. A balance bar 411 is fixedly installed on the top of the transformer body 4. A ratchet winding assembly and a drive motor 420 are fixedly installed on the top of the inner cavity of the transformer compartment 1. The ratchet winding assembly includes a frame 421, a ratchet 422, a winding drum 426, and a steel cable 413. The frame 421 is fixedly installed on the top of the inner cavity of the transformer compartment 1. The ratchet 422 is rotatably installed on the inner side of the frame 421. The winding drum 426 and the ratchet... The ratchet 422 is coaxially fixedly connected, and the steel cable 413 is wound around the outside of the winding drum 426. The other end of the steel cable 413 is fixedly connected to the balance bar 411. A buckle 425 that cooperates with the ratchet 422 is rotatably installed on the frame 421. A top block 423 is provided on the side of the buckle 425. A fourth spring 424 is provided between the top block 423 and the frame 421. The buckle 425 is used to limit the clockwise rotation of the ratchet 422. The output shaft of the drive motor 420 is coaxially fixedly connected to the ratchet 422.

[0067] Specifically, the transformer body 4 is stably fixed to the inner cavity of the transformer compartment 1 by screws 410. The balance bar 411 is rigidly connected to the transformer body 4. The two ends of the steel cable 413 are respectively connected to the winding drum 426 and the balance bar 411, forming an auxiliary pulling and fixing of the transformer body 4. Under the support of the fourth spring 424 and the top block 423, the buckle 425 always fits against the tooth surface of the ratchet 422, restricting the clockwise rotation of the ratchet 422 and preventing the winding drum 426 from reversing and loosening. When it is necessary to tighten the transformer body 4 a second time, the drive motor 420 starts and drives the ratchet 422 to rotate counterclockwise, which simultaneously drives the winding drum 426 to rotate and wind up the steel cable 413. The balance bar 411 applies a continuous tension force to the transformer body 4, which counteracts the displacement caused by the loosening of the screws 410, and realizes the self-adaptive tightening of the transformer body 4.

[0068] Based on the above embodiments, the one-way locking structure of ratchet 422 and buckle 425 ensures that the steel cable 413 will not loosen after winding, and always maintains a stable tension on the transformer body 4. This effectively solves the problem of loose screws 410 and equipment displacement caused by long-term operation vibration of the transformer, greatly improving the stability of transformer installation and operational safety. At the same time, it eliminates the need for manual shutdown for inspection and tightening, reducing the difficulty of equipment operation and maintenance, and is suitable for unattended operation scenarios of outdoor energy storage power stations.

[0069] A protective cylinder 5 is fixedly installed at the bottom of the transformer compartment 1. A fixed seat 510 is slidably connected inside the protective cylinder 5. The fixed seat 510 is fixed to the ground. A fiber rod 511 is fixedly installed on the fixed seat 510. A detection ball 513 is fixedly installed on the top of the fiber rod 511. A detection cylinder 512 corresponding to the position of the detection ball 513 is fixedly installed on the top of the inner cavity of the transformer compartment 1. The fiber rod 511 is connected to the transformer body 4 by a pull wire. When the detection ball 513 touches the detection cylinder 512, it triggers the drive motor 420 to start.

[0070] Specifically, the fixed base 510 is rigidly fixed to the ground and does not shift with the vibration of the transformer compartment 1. The fiber rod 511 is linked to the transformer body 4 through a pull wire. When the transformer body 4 experiences increased vibration due to loose installation, the vibration is transmitted to the fiber rod 511 through the pull wire, causing the fiber rod 511 and the detection ball 513 on the top to vibrate synchronously. When the vibration amplitude exceeds the safety threshold, the detection ball 513 touches the inner wall of the detection cylinder 512, triggering a control signal to start the drive motor 420, thus completing the automatic fastening of the transformer body 4. The protective cylinder 5 forms a protective barrier on the bottom of the fiber rod 511, preventing external debris from interfering with the normal vibration of the fiber rod 511.

[0071] Based on the above embodiments, a vibration detection structure with pull-wire linkage is used to achieve real-time passive detection of the loose state of the transformer body 4. The detection accuracy is high, and abnormal vibration of the transformer can be quickly captured. The tightening action is triggered simultaneously, forming a complete closed-loop protection of vibration detection and automatic tightening. This further improves the safety and stability of transformer operation and avoids safety hazards such as electrical connection failures and insulation wear caused by equipment loosening.

[0072] Shock-absorbing brackets 6 are installed at the bottom corners of the transformer compartment 1. Each shock-absorbing bracket 6 includes a shock-absorbing foot 623, a hydraulic rod 610, a first connecting plate 622, and a second connecting plate 611. The shock-absorbing foot 623 is fixed to the ground. The two ends of the hydraulic rod 610 are rotatably connected to the bottom of the transformer compartment 1 and the shock-absorbing foot 623, respectively. The two ends of the first connecting plate 622 and the second connecting plate 611 are rotatably connected to the bottom of the transformer compartment 1 and the shock-absorbing foot 623, respectively. The first connecting plate 622 and the second connecting plate 611 are hinged to each other.

[0073] Specifically, the shock-absorbing foot 623 is rigidly fixed to the ground, providing bottom support for the transformer compartment 1. The hydraulic rod 610, together with the first connecting plate 622 and the second connecting plate 611 which are hinged to each other, forms a parallel shock-absorbing and buffering structure. When the transformer compartment 1 is subjected to transportation bumps, operating vibrations or external vibration impacts, the hydraulic rod 610 absorbs the impact energy through its extension and retraction stroke. At the same time, the first connecting plate 622 and the second connecting plate 611 disperse the impact force through hinged rotation, converting the vertical vibration into a small horizontal displacement, which greatly reduces the vibration amplitude transmitted to the inside of the transformer compartment 1.

[0074] Based on the above embodiments, the multi-link shock absorption structure, which combines hydraulic rod 610 with hinged connecting plate, achieves multi-directional vibration buffering protection. It has a large shock absorption stroke and good buffering effect, which can effectively absorb various vibration impacts during transportation and operation, and avoid the problem of loosening or damage of internal components due to vibration. At the same time, it improves the environmental adaptability of transformer compartment 1, and can be adapted to transportation in complex road conditions and installation and use in complex outdoor sites.

[0075] An observation port 12 is provided on the door 11 of the transformer compartment 1. The observation port 12 is used to view the internal operating status of the transformer compartment 1 in real time.

[0076] Specifically, the observation port 12 is made of transparent tempered glass and is sealed and embedded in the middle of the door 11. A sealing strip is set at the joint with the door 11 to ensure the protection level of the compartment. Maintenance personnel can directly view the equipment operation status, instrument readings and structural condition inside the transformer compartment 1 through the observation port 12 without opening the door 11.

[0077] Based on the above embodiments, by setting an observation port 12 on the hatch 11, the convenience of daily equipment inspection is greatly improved. Daily inspection work can be completed without frequently opening and closing the hatch 11, reducing the probability of external dust and moisture entering the cabin, while reducing the difficulty of inspection operations for maintenance personnel and improving the maintenance efficiency of the equipment.

[0078] The air inlet 7 includes an air inlet pipe 713, a filter screen 712, and a dual fan 710. The air inlet pipe 713 is fixedly connected to the top of the transformer compartment 1. The filter screen 712 is fixedly installed at the air inlet end of the air inlet pipe 713. The dual fan 710 is fixedly installed in the inner cavity of the air inlet pipe 713 to force air into the transformer compartment 1 to ensure the air volume.

[0079] Specifically, the filter 712 filters the outside air entering the air inlet duct 713, intercepting dust, willow catkins, flying insects and other debris in the air. When the dual fan 710 is started, a stable negative pressure airflow is formed in the air inlet duct 713, continuously drawing outside air into the inner cavity of the transformer compartment 1, providing a stable cooling airflow for the equipment inside the compartment. The dual fan 710 can adjust its operating power according to the temperature inside the compartment to ensure the airflow requirements under different operating conditions.

[0080] Based on the above embodiments, the combination of filter 712 and dual fans 710 achieves the dual functions of filtration protection and forced air supply. This ensures a stable air intake for transformer compartment 1, improves overall heat dissipation efficiency, and effectively blocks external debris from entering the compartment, avoiding problems such as reduced insulation and decreased heat dissipation efficiency caused by dust accumulation on internal components. This further enhances the operational reliability and protection performance of transformer compartment 1.

[0081] This embodiment also provides a protection method for an energy storage transformer compartment with adaptive protection function, which adopts the above-mentioned energy storage transformer compartment with adaptive protection function and includes the following steps:

[0082] S1. When the transformer is running normally, the first dustproof net 345 in the air outlet duct 340 is kept ventilated, and the blockage detection component is in the initial standby state.

[0083] S2. When the first dustproof net 345 is blocked, causing the air pressure in the transformer compartment 1 to rise, the high-pressure gas pushes the first detection piston 311 to slide upward, which drives the second detection piston 316 to slide upward through the crankshaft connecting rod mechanism, triggering the trigger 318 to lock.

[0084] S3, the crankshaft connecting rod mechanism synchronously drives the transmission component to run, and drives the slider 332 to move the dust screen replacement component toward the air outlet 340;

[0085] S4. Release the fixation of the first dustproof net 345, the first dustproof net 345 falls off, the claw 335 unlocks and pushes the second dustproof net 344 to the installation position, completing the automatic replacement of the dustproof net;

[0086] S5 and trigger 318 unlock, all components reset to their initial positions, and the equipment returns to normal ventilation.

[0087] When the transformer is running under normal low load, the equipment maintains natural ventilation and heat dissipation. The blockage detection component and transmission component are in the initial standby state with no additional energy consumption. When the dust screen is blocked, the entire process of dust screen replacement is automatically triggered by the change in air pressure. After the replacement is completed, the trigger 318 is automatically unlocked, all structures are automatically reset, and normal operation is restored. When the transformer experiences loose or abnormal vibration, the ratchet winding component is automatically triggered by the vibration detection structure to complete the automatic secondary tightening of the transformer, achieving adaptive protection in all scenarios.
