Description

Technical Field

[0001] This invention relates to the field of busbar technology, specifically to an intelligent busbar with temperature monitoring function. Background Technology

[0002] Busbar trunking is a conductive device used in power systems. It is usually made of metal and its internal space is divided into several adjacent conductive channels for transmitting electrical energy. It is widely used in power supply and distribution sites such as high-rise buildings, factories, commercial centers, data centers, and lighting systems. It is mainly used to carry large current and high power electrical energy, such as driving large machinery or supplying the power needs of an entire building. A smart busbar trunking system with automatic temperature monitoring and alarm function, disclosed in publication number CN114583641A, includes a housing; two air intakes disposed on both sides inside the housing and connected by a connecting pipe; a processing box fixed to the housing, with a suction pump disposed on one side inside the processing box, the top of the suction pump connected to a delivery pipe, the top end of the delivery pipe passing through the processing box and the housing and extending into the interior of the housing, the end of the delivery pipe extending into the housing connected to the air intake; and a temperature sensor. The device includes a temperature sensor located inside the housing and a controller located on one side inside the processing box. The controller is equipped with an alarm and, through the temperature sensor, can detect the temperature signal. After processing and controlling the signal, the controller powers on the suction pump to absorb the heat accumulated inside and then discharge it. This achieves intelligent monitoring of the temperature inside the busbar trunking, which is simple to operate, convenient to use, and can control the temperature in a timely manner to avoid excessive temperature and fire, thereby improving the safety of the busbar trunking during use. While the above methods can absorb the heat accumulated inside, the temperature sensor probe remains exposed when the internal temperature of the busbar trunking is too high and triggers an alarm. Prolonged exposure to high temperatures not only accelerates the aging process of the sensor material, leading to decreased sensor accuracy, slower response speed, or complete failure, thus increasing maintenance costs, but also causes the sensor material to expand or contract, resulting in probe structural deformation or damage. This can prevent the sensor from triggering an alarm in time, endangering the safety of the busbar trunking. In cases of inaccurate measurements or sensor failure, the internal temperature of the busbar trunking may far exceed the safe range, yet the controller may still not trigger an alarm. In such situations, the busbar trunking could overheat and cause a serious accident such as a fire or explosion.

[0003] Therefore, this invention proposes an intelligent busbar trunking with temperature monitoring function to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent busbar trunking system with temperature monitoring capabilities, which can effectively solve the problems in existing technologies.

[0005] To achieve the above objectives, the present invention can be accomplished through the following technical solutions: An intelligent busbar trunking system with temperature monitoring function includes a busbar trunking housing. A side plate is fixedly connected to one side of the busbar trunking housing, and a temperature sensor body is fixedly connected to one side of the side plate. A probe body is fixedly connected to the upper end of the temperature sensor body, and the probe body is fixedly connected to the side plate through the side plate. The side plate has symmetrically arranged exhaust holes on the side near the temperature sensor body, and heat dissipation holes are equidistantly arranged on the side away from the exhaust holes. The system also includes a high-temperature protection mechanism and a high-temperature exhaust mechanism. The high-temperature protection mechanism includes symmetrically arranged heat insulation frames located on both sides of the probe body. The high-temperature protection mechanism is used to simultaneously protect the probe body when an alarm is triggered due to abnormal temperature at the connection of the busbar trunking housing. The high-temperature exhaust mechanism is used to simultaneously exhaust high-temperature air when an abnormal temperature occurs at the connection of the busbar trunking housing.

[0006] As a further aspect of the present invention: a sliding column is fixedly connected to each of the two heat insulation frames on opposite sides, and a support block is slidably connected to the outer surface of each sliding column, and the support block is fixedly connected to the inner side wall of the side plate.

[0007] As a further embodiment of the present invention: a disc is fixedly connected to the end of each sliding column away from the heat insulation frame, a connecting plate is rotatably connected to the outer surface of each disc, a lifting block is rotatably connected between the ends of the two connecting plates away from the disc, a lifting column is fixedly connected to the upper end of the lifting block, a support plate is slidably connected to the outer surface of the lifting column, and the support plate is fixedly connected to the inner side wall of the side plate.

[0008] As a further embodiment of the present invention: a double-stroke memory alloy wire is fixedly connected to the upper end face of the lifting block, and the end of the double-stroke memory alloy wire away from the lifting block is fixedly connected to the lower end face of the support plate, and the double-stroke memory alloy wire is sleeved on the outer surface of the lifting column.

[0009] As a further embodiment of the present invention: a sealing plate is fixedly connected to one of the heat insulation frames on the side away from the sliding column, and a sealing groove is provided on the side of the other heat insulation frame near the sealing plate, wherein the sealing plate and the sealing groove are interlocked with each other.

[0010] As a further embodiment of the present invention: each heat insulation frame is fixedly connected to a limiting plate, each limiting plate has a connecting column attached to its upper surface, each connecting column has a mounting block fixedly connected to its upper end, each mounting block has a baffle fixedly connected to its side wall, each baffle is vertically slidably connected to the inner side wall of the side plate, and each baffle covers the exhaust hole, and each mounting block has a counterweight fixedly connected to its upper surface.

[0011] As a further aspect of the present invention: the high-temperature exhaust mechanism includes an exhaust channel, which is fixedly connected to the inner wall of the side plate near the heat dissipation hole. An exhaust fan is fixedly connected inside the exhaust channel, and air inlets are equidistantly provided on the side of the exhaust channel away from the heat dissipation hole.

[0012] As a further embodiment of the present invention: an inclined plate is fixedly connected to the side of the side plate near the heat dissipation hole, and a cover plate is covered on the side of the inclined plate away from the side plate. A rotating shaft is fixedly connected through the upper end of the cover plate, and vertical plates are rotatably connected to both sides of the rotating shaft. The vertical plates are all fixedly connected to the side wall of the side plate.

[0013] As a further aspect of the present invention: the exhaust fan is electrically connected to a first contact and a second contact, and a fixing block is fixedly connected to each of the opposite sides of the first contact and the second contact, and the two fixing blocks are respectively fixedly connected to the side walls of the two heat insulation frames.

[0014] Compared with the prior art, the present invention provides an intelligent busbar trunking with temperature monitoring function, which has the following beneficial effects: 1. Through the high-temperature protection mechanism, when the temperature at the connection of the busbar trunking shell is too high and an early warning is triggered, the heat insulation frames on both sides will automatically move closer to each other and cover the probe body. This not only effectively reduces the direct impact of high temperature on the probe body material and slows down the aging of the material, thereby extending the service life of the sensor and reducing maintenance costs caused by frequent sensor replacement, but also creates a relatively stable temperature environment for the sensor after the heat insulation frame covers the probe body. This helps maintain the sensor's subsequent measurement accuracy and rapid response capability, ensuring that the sensor can accurately and timely detect temperature changes inside the busbar trunking. Furthermore, by ensuring the normal operation of the sensor and timely alarm function of the probe body, the risk of serious accidents such as fires or explosions caused by overheating of the busbar trunking is greatly reduced, thereby improving the safety and reliability of the entire power system. The sealing plate and sealing groove improve the sealing performance of the two heat insulation frames after they are fitted together, further preventing high-temperature air from coming into contact with the probe body through the gap between the two heat insulation frames. The good sealing performance not only prevents the flow of high-temperature air and reduces heat transfer, but also improves the overall heat insulation performance of the heat insulation frame and further protects the probe body. Moreover, the probe body works in a stable and reliable environment with relatively small performance changes, which allows maintenance personnel to formulate maintenance plans more accurately, discover potential problems in advance and carry out preventive maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0015] 2. Through the setting of limit plates, connecting columns, mounting blocks, and counterweights, the baffle can be pushed up simultaneously when the heat insulation frames on both sides approach each other to protect the probe body, opening the exhaust port. This allows the high-temperature air near the probe body to be discharged after the probe body issues a high-temperature detection warning. This not only opens the exhaust port in time to discharge high-temperature air, reducing the exposure time of the probe body in the high-temperature environment, reducing the risk of secondary damage, and extending the service life of the probe body, but also allows the probe body to quickly return to a relatively normal temperature environment, ensuring that it can accurately monitor the internal temperature changes of the busbar trunking and provide reliable data for subsequent safety assessments and decisions.

[0016] 3. The high-temperature exhaust mechanism allows the exhaust fan to be activated simultaneously while the heat-insulating frames are close together to protect the probe body from high temperatures. This exhausts the high-temperature air from the connection points of the busbar trunking, quickly dissipating the heat generated inside the busbar trunking, reducing its overall temperature, preventing insulation aging and electrical performance degradation caused by overheating, and ensuring the safe and stable operation of the busbar trunking. Furthermore, timely exhaust of high-temperature air prevents system failures caused by busbar trunking overheating, reduces power outages, ensures the continuity and stability of power supply, and improves the overall operating efficiency of the system. Additionally, the exhaust fan's prolonged operation keeps the motor running, generating electrical losses such as coil heating and the conversion of electrical energy into heat. The linkage design allows the exhaust fan to operate on demand, reducing unnecessary electrical energy consumption and lowering the risk of motor overheating due to prolonged operation. This helps maintain stable motor electrical performance and improves the overall operating efficiency of the exhaust fan.

[0017] 4. With the addition of cover plates, inclined plates, vertical plates, and rotating shafts, the system can automatically cover the inclined plates when the exhaust fan stops working, thus shielding the heat dissipation holes. This not only effectively prevents dust from entering and keeps the inside of the busbar trunking clean, ensuring that electrical components operate in a good environment, but also prevents moisture from entering, reducing the humidity inside the busbar trunking, protecting internal components from moisture corrosion, and improving the reliability and service life of the equipment.

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] This embodiment provides an intelligent busbar trunking system with temperature monitoring capabilities, such as... Figure 1 - Figure 7 As shown, the device includes a busbar housing 1, a side plate 2 fixedly connected to one side of the busbar housing 1, a temperature sensor body 3 fixedly connected to one side of the side plate 2, a probe body 4 fixedly connected to the upper end of the temperature sensor body 3, and the probe body 4 being fixedly connected to the side plate 2 through the side plate 2. The side plate 2 has symmetrically arranged vent holes 7 on the side near the temperature sensor body 3, and heat dissipation holes 8 equidistantly arranged on the side away from the vent holes 7. The device also includes a high-temperature protection mechanism and a high-temperature discharge mechanism. The high-temperature protection mechanism includes symmetrically arranged heat insulation frames 502, which are located on both sides of the probe body 4. The high-temperature protection mechanism is used to simultaneously protect the probe body 4 during the process of triggering an alarm due to abnormal temperature at the connection of the busbar housing 1.

[0023] In this embodiment, as Figure 4As shown, sliding columns 512 are fixedly connected to the opposite sides of the two heat insulation frames 502. Support blocks 503 are slidably connected to the outer surface of the sliding columns 512. The support blocks 503 are fixedly connected to the inner side wall of the side plate 2. When the sliding columns 512 slide on the support blocks 503, they will push the two heat insulation frames 502 to move closer or further apart.

[0024] In this embodiment, as Figure 4 As shown, a disc 508 is fixedly connected to the end of the sliding column 512 away from the heat insulation frame 502. A connecting plate 509 is rotatably connected to the outer surface of the disc 508. A lifting block 510 is rotatably connected between the ends of the two connecting plates 509 away from the disc 508. A lifting column 506 is fixedly connected to the upper end of the lifting block 510. A support plate 501 is slidably connected to the outer surface of the lifting column 506. The support plate 501 is fixedly connected to the inner side wall of the side plate 2. When the lifting block 510 pulls the lifting column 506 to slide up and down on the support plate 501, the lifting block 510 will pull the sliding column 512 to slide horizontally on the support block 503 synchronously through the connecting plate 509 and the disc 508.

[0025] In this embodiment, as Figure 4 As shown, a double-stroke memory alloy wire 511 is fixedly connected to the upper end face of the lifting block 510. The end of the double-stroke memory alloy wire 511 away from the lifting block 510 is fixedly connected to the lower end face of the support plate 501. The double-stroke memory alloy wire 511 is sleeved on the outer surface of the lifting column 506. When the double-stroke memory alloy wire 511 comes into contact with high-temperature air, it will push the lifting block 510 to drive the lifting column 506 to slide downward. Conversely, when the double-stroke memory alloy wire 511 comes into contact with low-temperature air, it will contract and pull the lifting block 510 to drive the lifting column 506 to rise.

[0026] In this embodiment, as Figure 4 As shown, a sealing plate 504 is fixedly connected to one of the heat insulation frames 502 on the side away from the sliding column 512, and a sealing groove 505 is opened on the side of the other heat insulation frame 502 near the sealing plate 504. The sealing plate 504 and the sealing groove 505 are interlocked. When the two heat insulation frames 502 move closer to each other, the sealing plate 504 will be simultaneously inserted into the sealing groove 505, thereby improving the sealing performance of the two heat insulation frames 502 after they are joined.

[0027] In this embodiment, as Figure 3 and Figure 5As shown, each heat insulation frame 502 has a fixedly connected limiting plate 513 inside. Each limiting plate 513 has a connecting column 514 attached to its upper surface. Each connecting column 514 has a fixedly connected mounting block 515 at its upper end. Each mounting block 515 has a fixedly connected baffle 507 on its side wall. Each baffle 507 is vertically slidably connected to the inner side wall of the side plate 2 and covers the exhaust hole 7. Each mounting block 515 has a fixedly connected counterweight 516 on its upper surface. When the heat insulation frame 502 moves the limiting plate 513, the limiting plate 513 will push the connecting column 514 upward by tilting its upper surface, causing the mounting block 515 and the baffle 507 to move upward synchronously, so that the baffle 507 and the exhaust hole 7 are separated.

[0028] In existing technologies, when the internal temperature of the busbar trunking is too high and triggers an alarm, the temperature sensor probe remains exposed. Prolonged exposure to high temperatures not only accelerates the aging process of the sensor material, leading to decreased sensor accuracy, slower response speed, or complete failure, thus increasing maintenance costs, but also causes the sensor material to expand or contract, resulting in probe structural deformation or damage. This can prevent the sensor from triggering an alarm in time, endangering the safety of the busbar trunking. Due to inaccurate measurements or sensor failure, the internal temperature of the busbar trunking may far exceed the safe range, but the controller may still not trigger an alarm. In such cases, the busbar trunking may overheat and cause a serious accident such as a fire or explosion. Compared to existing technologies, this new technology can trigger an alarm process at the connection point of the busbar trunking housing 1 when the temperature is too high. In the process, the heat insulation frames 502 on both sides are automatically driven to approach each other and cover the probe body 4. This not only effectively reduces the direct impact of high temperature on the material of the probe body 4 and slows down the aging of the material, thereby extending the service life of the sensor and reducing the maintenance costs caused by frequent sensor replacement, but also creates a relatively stable temperature environment for the sensor after the heat insulation frame 502 covers the probe body 4. This helps maintain the subsequent measurement accuracy and rapid response capability of the sensor, ensuring that the sensor can accurately and timely detect the temperature changes inside the bus trunking. Furthermore, by ensuring the normal operation of the sensor in the probe body 4 and the timely alarm function, the risk of serious accidents such as fires or explosions caused by overheating of the bus trunking is greatly reduced, thereby improving the safety and reliability of the entire power system. The sealing plate 504 and sealing groove 505 improve the sealing performance of the heat insulation frames 502 after they are fitted together, further preventing high-temperature air from passing through the gap between the two heat insulation frames 502 and coming into contact with the probe body 4. The good sealing performance not only prevents the flow of high-temperature air and reduces heat transfer, but also improves the overall heat insulation performance of the heat insulation frame 502 and further protects the probe body 4. Moreover, the probe body 4 works in a stable and reliable environment with relatively small performance changes, which allows maintenance personnel to formulate maintenance plans more accurately, discover potential problems in advance and carry out preventive maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0029] At other levels, this embodiment also provides a high-temperature exhaust mechanism for simultaneously exhausting high-temperature air when an abnormal temperature occurs at the connection of the busbar housing 1, such as... Figure 1 - Figure 3 , Figure 6 and Figure 7 As shown, the high-temperature exhaust mechanism includes an exhaust channel 608, which is fixedly connected to the inner wall of the side plate 2 near the heat dissipation hole 8. An exhaust fan 609 is fixedly connected inside the exhaust channel 608, and an air inlet 610 is provided at equal intervals on the side of the exhaust channel 608 away from the heat dissipation hole 8.

[0030] In this embodiment, as Figure 7 As shown, a sloping plate 605 is fixedly connected to the side of the side plate 2 near the heat dissipation hole 8. A cover plate 601 covers the side of the sloping plate 605 away from the side plate 2. A rotating shaft 607 is fixedly connected through the upper end of the cover plate 601. Vertical plates 606 are rotatably connected to both sides of the rotating shaft 607. The vertical plates 606 are fixedly connected to the side wall of the side plate 2. When there is airflow inside the heat dissipation hole 8, it will push the cover plate 601 to move upward and separate from the sloping plate 605. At this time, the airflow will be discharged through the heat dissipation hole 8. When the airflow disappears, the cover plate 601 will automatically descend under its own weight and cover the sloping plate 605 to block the heat dissipation hole 8.

[0031] In this embodiment, as Figure 3 and Figure 7 As shown, the exhaust fan 609 is electrically connected to a first contact 603 and a second contact 604. A fixing block 602 is fixedly connected to each of the opposite sides of the first contact 603 and the second contact 604. The two fixing blocks 602 are respectively fixedly connected to the side walls of the two heat insulation frames 502. When the first contact 603 and the second contact 604 are in contact, the exhaust fan 609 will be turned on and will work. Conversely, when the first contact 603 and the second contact 604 are separated, the exhaust fan 609 will stop running.

[0032] Compared with existing technologies, the simultaneous activation of the exhaust fan 609 during the process of the heat insulation frames 502 approaching each other to provide high-temperature protection for the probe body 4, and the discharge of high-temperature air from the connection of the busbar housing 1, not only quickly dissipates the heat generated inside the busbar, reducing the overall temperature of the busbar and preventing problems such as aging of insulation materials and degradation of electrical performance due to overheating, thus ensuring the safe and stable operation of the busbar, but also timely discharge of high-temperature air can prevent system failures caused by overheating of the busbar, reduce the occurrence of power outages, ensure the continuity and stability of power supply, and improve the overall operating efficiency of the system. Furthermore, the long-term operation of the exhaust fan 609 will keep the motor in a continuous working state, generating certain electrical losses, such as coil heating and the conversion of electrical energy into heat energy. The linkage design allows the exhaust fan 609 to work on demand, reducing unnecessary electrical energy consumption, lowering the risk of motor overheating due to long-term operation, helping to maintain the stability of the motor's electrical performance, and improving the overall working efficiency of the exhaust fan 609.

[0033] The overall working process and principles involved in the above embodiments are as follows: It should be noted that: Two-way memory effect alloys (also known as dual-phase alloys or dual-shape memory alloys) are a class of alloy materials with special shape memory effects, which can realize two different shapes at different temperatures. The most common two-way memory effect alloy is nickel-titanium alloy (Ni-Ti alloy), also known as "Nitino" alloy or "superelastic alloy", which usually has the following two shapes: high-temperature phase and low-temperature phase. In the high-temperature phase (usually above room temperature), the material is in an elastic shape and can undergo significant elastic deformation; while in the low-temperature phase (usually below room temperature), the material will return to the pre-set initial shape. Specifically, the transformation temperature (two-way transformation temperature) of nickel-titanium alloy (Ni-Ti alloy) can be adjusted according to the alloy composition and processing. Typically, the high-temperature phase transformation temperature range is around 100℃, and the low-temperature phase transformation temperature range is around 30℃. This range can be adjusted according to the specific application requirements. It should be noted that the shape memory process of the two-way memory alloy is reversible and can switch between high and low temperatures multiple times while maintaining the same memory effect. In the application document, the contracted state of the two-way memory alloy wire 511 is the low-temperature phase, and the extended state is the high-temperature phase.

[0034] During the operation of the busbar trunking, as the temperature rises at the connection point of the busbar trunking shell 1 near the side plate 2, it comes into contact with the probe body 4 that penetrates the side plate 2. The probe body 4 transmits data to the temperature sensor body 3 for early warning. Simultaneously, the high temperature detected by the probe body 4 also comes into contact with the double-pass memory alloy wire 511. This high temperature triggering the early warning simultaneously triggers the high-temperature phase of the double-pass memory alloy wire 511, causing it to extend and push the lower end of the lifting block 510 downwards. At the same time, it pulls the lifting column 506 to slide downwards synchronously on the support plate 501. Since both sides of the lifting block 510 are rotatably connected to connecting plates 509, with the end of the connecting plate 509 away from the lifting block 510 rotatably connected to the outer surface of the disc 508, and a sliding column 512 is fixedly connected to the side wall of the disc 508, slidingly connected to the support block 503, the lifting block 510 pushes the lower end of the connecting plate 509 downwards synchronously. The drop causes the connecting plate 509 to change state, pulling the disc 508 and pushing the sliding column 512 to slide on the support block 503. This causes the heat insulation frame 502 connected to the end of the sliding column 512 away from the disc 508 to move closer to each other and cover the probe body 4 between the heat insulation frames 502. This isolates the external air from the probe body 4, which not only effectively reduces the direct effect of high temperature on the probe body 4 material and slows down the aging of the material, thereby extending the service life of the sensor and reducing maintenance costs caused by frequent sensor replacement, but also creates a relatively stable temperature environment for the sensor after the heat insulation frame 502 covers the probe body 4. This helps maintain the subsequent measurement accuracy and rapid response capability of the sensor, ensuring that the sensor can accurately and timely detect temperature changes inside the busbar trunking. Furthermore, by ensuring the normal operation of the sensor in the probe body 4 and the timely alarm function, it greatly reduces the risk of serious accidents such as fires or explosions caused by overheating of the busbar trunking, thereby improving the safety and reliability of the entire power system. As the two heat insulation frames 502 move closer to each other, the sealing plate 504 connected to the side wall of one heat insulation frame 502 will gradually move closer to the sealing groove 505 opened on the side wall of the other heat insulation frame 502 until the sealing plate 504 is inserted into the sealing groove 505. This improves the sealing performance of the two heat insulation frames 502 after they are fitted together, further preventing high-temperature air from passing through the gap between the two heat insulation frames 502 and coming into contact with the probe body 4. The good sealing performance not only prevents the flow of high-temperature air and reduces heat transfer, but also improves the overall heat insulation performance of the heat insulation frame 502, further protecting the probe body 4. Moreover, the probe body 4 works in a stable and reliable environment, and its performance changes relatively little. This allows maintenance personnel to formulate maintenance plans more accurately, discover potential problems in advance, and carry out preventive maintenance, further improving maintenance efficiency and reducing maintenance costs. As the heat insulation frames 502 approach each other, the heat insulation frames 502 will drive the limiting plate 513 connected to the inner bottom to move horizontally in sync. At this time, the limiting plate 513 will push the connecting column 514 attached to the upper end to rise, and through the mounting block 515 connected to the upper end of the connecting column 514, push the baffle 507 to slide vertically upward on the side wall of the side plate 2, opening the exhaust hole 7 opened on the side plate 2. Thus, after the two heat insulation frames 502 isolate the probe body 4, the high-temperature air near the probe body 4 can be discharged. This not only opens the exhaust hole 7 in time to discharge the high-temperature air, reducing the exposure time of the probe body 4 in the high-temperature environment, reducing the risk of secondary damage, and extending the service life of the probe body 4, but also allows the probe body 4 to quickly return to a relatively normal temperature environment in time, ensuring that it can accurately monitor the internal temperature changes of the busbar trunking and provide reliable data for subsequent safety assessment and decision-making. As the two heat insulation frames 502 approach each other, the heat insulation frames 502 will drive the fixed blocks 602 connected to the side walls to move synchronously, and push the first contact 603 and the second contact 604 connected to the side walls of the fixed blocks 602 to approach each other. When the heat insulation frames 502 are in contact with each other, the first contact 603 and the second contact 604 will also come into contact at the same time. At this time, through the electrical connection between the first contact 603, the second contact 604 and the exhaust fan 609, the exhaust fan 609 will be turned on and work synchronously in the exhaust channel 608. As the exhaust fan 609 operates, the exhaust fan 609 will draw the high temperature generated at the busbar connection into the air inlet 610 through negative pressure, and then discharge the high temperature through the exhaust channel 608 and the heat dissipation hole 8. At this time, when the airflow formed by the exhaust fan 609 passes through the heat dissipation hole 8, it will apply a thrust to the cover plate 601 covering the inclined plate 605, pushing the cover plate 601 to drive the rotating shaft 607 between the two vertical plates 606. The upward rotation of the cover plate 601 moves away from the inclined plate 605, opening the heat dissipation hole 8 and allowing the exhaust fan 609 to expel hot air. This not only quickly dissipates the heat generated inside the busbar trunking, reducing the overall temperature of the busbar trunking and preventing insulation material aging and electrical performance degradation caused by overheating, thus ensuring the safe and stable operation of the busbar trunking, but also timely exhaust of hot air can prevent system failures caused by busbar trunking overheating, reduce the occurrence of power outages, ensure the continuity and stability of power supply, and improve the overall operating efficiency of the system. Furthermore, the long-term operation of the exhaust fan 609 will keep the motor in a continuous working state, generating certain electrical losses, such as coil heating and the conversion of electrical energy into heat energy. The linkage design allows the exhaust fan 609 to work on demand, reducing unnecessary electrical energy consumption, lowering the risk of motor overheating due to long-term operation, helping to maintain the stable electrical performance of the motor, and improving the overall working efficiency of the exhaust fan 609. When the air temperature at the busbar connection drops, the low-temperature air comes into contact with the dual-path memory alloy wire 511, triggering the low-temperature phase of the dual-path memory alloy wire 511. This causes the dual-path memory alloy wire 511 to move from an extended state to a contracted state. At this time, the dual-path memory alloy wire 511 pulls the lifting block 510 to rise. The lifting block 510, through the connecting plate 509, the disc 508, and the sliding column 512, pulls the two heat insulation frames 502 to move horizontally relative to each other and separate them, exposing the probe body 4 inside the two heat insulation frames 502, so that the probe body 4 can continue to detect the temperature at the connection of the busbar. As the two heat insulation frames 502 move away from each other, the limiting plate 513 inside the heat insulation frame 502 will move synchronously. At this time, the baffle 507 will be affected by the counterweight 516 connected to both ends of the mounting block 515, and will automatically push the connecting column 514 to descend, so that the connecting column 514 will always be in contact with the upper end surface of the limiting plate 513. At the same time, it will pull the baffle 507 to slide down on the side wall of the side plate 2 and cover the exhaust hole 7 opened on the side plate 2 again. As the two heat insulation frames 502 move away from each other, the heat insulation frames 502 will cause the first contact 603 and the second contact 604 to separate through the fixing block 602 connected to the side wall. After the first contact 603 and the second contact 604 are completely separated, the exhaust fan 609 will stop working. At this time, the thrust on the cover plate 601 set above the inclined plate 605 will disappear, and the cover plate 601 will automatically drive the rotating shaft 607 to rotate downward under its own weight, covering the inclined plate 605. Since the inclined plate 605 is inclined, the cover plate 601 can completely cover the inclined plate 605 during the downward rotation, blocking the heat dissipation hole 8. This not only effectively prevents dust from entering and keeps the inside of the busbar trunking clean, ensuring that electrical components operate in a good environment, but also prevents moisture in the air from entering, reducing the humidity inside the busbar trunking, protecting the internal components from moisture corrosion, and improving the reliability and service life of the equipment.
