Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear technology, and in particular to an energy-saving high-voltage switchgear with semiconductor dehumidification function. Background Technology

[0002] The semiconductor dehumidification function of high-voltage switchgear is a dehumidification device specifically designed for high-voltage distribution cabinets in the power industry. Its main function is to reduce the humidity inside the cabinet through semiconductor refrigeration technology, preventing equipment failure and insulation degradation caused by moisture. This device utilizes the cooling effect of a semiconductor refrigeration chip (also known as a Peltier element). When current passes through the semiconductor refrigeration chip, one side cools and the other side heats. The temperature of the cooling side decreases, causing water vapor in the air to condense into water droplets. The condensed water droplets are collected through the flow guide design inside the device and discharged outside the cabinet through a drain pipe. Some advanced dehumidification devices are also equipped with humidity sensors and intelligent control systems, which can automatically start or stop the dehumidification function according to the humidity inside the cabinet.

[0003] However, existing energy-saving high-voltage cabinets with semiconductor dehumidification functions still have some shortcomings in practical applications. For example, when extracting air with different humidity levels, existing equipment usually controls the gas intake speed to ensure the air residence time on the semiconductor cooling chip, thereby achieving the dehumidification effect. However, when there are different humidity levels at different heights inside the high-voltage cabinet, this single adjustment method is not flexible or efficient enough. Specifically, when facing such complex situations, existing equipment needs to constantly adjust the speed of the exhaust fan and the moving speed of the air intake head to adapt to the humidity differences at different heights. This frequent adjustment is not only cumbersome to operate, but also significantly affects the speed of moisture processing inside the high-voltage cabinet, reducing dehumidification efficiency. Therefore, how to improve the flexibility and efficiency of dehumidification devices has become a technical problem that needs to be solved.

[0004] Therefore, an energy-saving high-voltage switchgear with semiconductor dehumidification function was proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing an energy-saving high-voltage switchgear with semiconductor dehumidification function.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an energy-saving high-voltage cabinet with semiconductor dehumidification function, comprising a cabinet body, with dehumidifier housings fixedly connected to both ends of the bottom of the cabinet body, and suction fans fixedly connected through the side walls of the dehumidifier housings. Fixed plates are fixedly connected to the inner side of the cabinet body relative to the upper position of the dehumidifier housings. A flexible hose is fixedly connected to the suction end of the suction fan. An adjustment mechanism for adjusting the suction position of the flexible hose is provided on the fixed plate. A middle plate is fixedly connected to the inner side of the dehumidifier housing relative to the upper position of the suction fan outlet. The top of the middle plate... An outlet is provided through the end of the dehumidifier housing. A semiconductor plate is provided on the inner side of the dehumidifier housing relative to the upper part of the middle plate. Several upper plates are fixedly connected at equal intervals on one side of the inner wall of the dehumidifier housing. Lower plates are fixedly connected on the other side of the inner wall of the dehumidifier housing relative to the positions between the upper plates. The side walls of the upper and lower plates are in contact with the side wall of the semiconductor plate. A side frame is fixedly connected through the side wall of the dehumidifier housing. A side plate is fixedly connected to the side wall of the semiconductor plate relative to the position inside the side frame. An upper lifter is fixedly connected to the inner side of the side frame. The output end of the upper lifter is fixedly connected to the side wall of the side plate.

[0007] In the above technical solution, a humidity sensor is fixedly connected to the inner side of the dehumidifier housing relative to the lower part of the middle plate. The humidity sensor is electrically connected to the upper lifting device through the controller. Several exhaust vents are equidistantly opened at the top of the dehumidifier housing.

[0008] In the above technical solution, the adjustment mechanism further includes an adjustment frame, with support plates fixedly connected to both the upper and lower ends of the side wall of the fixed plate, and a threaded rod rotatably connected between the support plates. A drive motor is fixedly connected to the bottom end of one of the support plates, and the output end of the drive motor passes through the support plate and is fixedly connected to the side end of the threaded rod. A drive block is fixedly connected to the side wall of the adjustment frame, and the threaded rod is threadedly connected to the inner side wall of the drive block. A T-shaped rod is slidably connected to the inner side of the adjustment frame, and a suction head is fixedly connected to the side wall of the T-shaped rod. The other end of the hose is fixedly connected to the bottom end of the suction head. A secondary adjustment mechanism is also provided for further adjusting the position of the suction head according to the humidity inside the cabinet.

[0009] In the above technical solution, a guide rod is fixedly connected between the support plates, and the guide rod is disposed through the inner sidewall of the drive block.

[0010] In the above technical solution, the auxiliary adjustment mechanism further includes a lower lift and a lower humidity sensor. Several lower humidity sensors are provided and are equidistantly fixedly connected to the inside of the cabinet. The lower lift is fixedly connected to the side wall of the T-shaped rod. A circular hole is opened on the side wall of the T-shaped rod relative to the lower lift. A circular rod is slidably connected in the circular hole. The lower lift is fixedly connected to the side wall of the circular rod. An upper right-angle plate with an inclined surface is provided on the side wall of the fixed plate relative to the lower humidity sensor. The side wall of the upper right-angle plate is fixedly connected to the fixed plate by a connecting block. The drive motor is electrically connected to the lower lift through a controller.

[0011] In the above technical solution, the side end of the T-shaped rod penetrates the outer wall of the adjustment frame, and two pairs of return springs are fixedly connected between the side wall of the T-shaped rod and the inner side of the adjustment frame.

[0012] In the above technical solution, the lower humidity sensor is located below the component installation position inside the cabinet, and the lower humidity sensor is electrically connected to the lower lifter through the controller.

[0013] In the above technical solution, furthermore, a lower right-angled plate with an inclined surface is fixedly connected between the upper right-angled plate and the fixed plate. The side wall of the upper right-angled plate is provided with a groove that is horizontal to the inclined surface of the lower right-angled plate. The outer wall of the round rod is provided with an annular groove. The width of the groove is the same as the diameter of the annular groove on the round rod. A photoelectric reflective sensor is fixedly connected to the rear side of the T-shaped rod. Both the upper and lower right-angled plates are made of reflective materials with high reflectivity and good optical properties, which can reflect the signal emitted by the photoelectric reflective sensor back. The photoelectric reflective sensor is electrically connected to the lower lifting device through the controller.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting up an upper plate, a lower plate, and a lifting device, forms an extended air duct path within the dehumidifier casing. When the upper humidity sensor detects high humidity in the intake air, it quickly controls the semiconductor plate to contact the side walls of the upper and lower plates. This causes the drawn-in air to pass through an S-shaped path formed by the upper and lower plates, increasing the residence time of the air near the semiconductor plate for dehumidification. If the humidity in the intake air decreases, the upper lifting device will control the semiconductor plate to reset, and the drawn-in air will quickly pass through the gap between the upper and lower plates and the semiconductor plate. This ensures good dehumidification under different humidity conditions, eliminating the need for frequent adjustments to the exhaust fan speed and thus achieving energy savings.

[0015] 2. Through the structural design of the adjustment mechanism and the auxiliary adjustment mechanism, this invention can not only drive the suction head to move up and down to comprehensively extract and dehumidify the air inside the cabinet, but also, when the humidity of the air at the rear of the cabinet is high, the lower humidity sensor detects that the humidity has reached a certain value and controls the lower lifter to start, extending the round rod. Under the pressure of the inclined surface of the upper right-angle plate, the suction head moves to the rear of the cabinet. It can flexibly change the suction position of the suction head according to the air humidity, and the suction head can more accurately treat the humidity at different heights and positions, further improving the dehumidification efficiency.

[0016] 3. The present invention, through the design of the upper and lower right-angle plates, can cut the upper and lower right-angle plates according to the size of the components inside the high-voltage cabinet during installation. This allows for flexible adjustment of the depth of the suction head moving backward into the cabinet according to the size of the components, further improving the ease of operation of the device.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] In practical use, it was found that when extracting air with different humidity levels, existing equipment usually controls the gas intake speed to ensure the residence time of the air on the semiconductor cooling chip, thereby achieving the dehumidification effect. However, when there are different humidity levels at different heights inside the high-voltage cabinet, this single adjustment method is not flexible or efficient enough. Specifically, when facing such complex situations, existing equipment needs to constantly adjust the speed of the exhaust fan and the moving speed of the air intake head to adapt to the humidity differences at different heights. This frequent adjustment is not only cumbersome to operate, but also significantly affects the speed of processing moisture inside the high-voltage cabinet and reduces dehumidification efficiency. To solve the above problems, the following structure was invented.

[0022] like Figures 1-9The energy-saving high-voltage cabinet with semiconductor dehumidification function shown includes a cabinet body 1. Dehumidifier housings 2 are fixedly connected to both ends of the bottom of the cabinet body 1. Suction fans 3 are fixedly connected through the side walls of the dehumidifier housings 2. Fixing plates 4 are fixedly connected to the inner side of the cabinet body 1 relative to the upper part of the dehumidifier housings 2. A flexible hose 5 is fixedly connected to the suction end of the suction fan 3. The fixing plates 4 are equipped with an adjustment mechanism for adjusting the suction position of the flexible hose 5. A middle plate 6 is fixedly connected to the inner side of the dehumidifier housings 2 relative to the upper part of the air outlet of the suction fan 3. An outlet 7 is opened through the top of the middle plate 6. A semiconductor plate 8 is provided on the inner side relative to the upper part of the middle plate 6. Several upper plates 9 are fixedly connected at equal intervals on one side of the inner wall of the dehumidifier housing 2. Lower plates 10 are fixedly connected on the other side of the inner wall of the dehumidifier housing 2 relative to the positions of the upper plates 9. The side walls of the several upper plates 9 and the lower plates 10 are in contact with the side wall of the semiconductor plate 8. A side frame 11 is fixedly connected through the side wall of the dehumidifier housing 2. A side plate 12 is fixedly connected to the side wall of the semiconductor plate 8 relative to the position inside the side frame 11. An upper lift 13 is fixedly connected to the inner side of the side frame 11. The output end of the upper lift 13 is fixedly connected to the side wall of the side plate 12.

[0023] An upper humidity sensor 14 is fixedly connected to the inside of the dehumidifier housing 2 relative to the lower part of the middle plate 6. The upper humidity sensor 14 is electrically connected to the upper lifting device 13 through the controller. Several exhaust vents 15 are equidistantly opened at the top of the dehumidifier housing 2.

[0024] The working principle of the semiconductor dehumidifier is as follows: the air inside the cabinet 1 is drawn in by the suction fan 3 and discharged into the dehumidifier housing 2 through the hose 5. Then it flows to the side of the semiconductor plate 8. The water vapor in the air condenses into water at the cold end under the cooling effect of the semiconductor plate 8. The condensed water is discharged out of the cabinet 1 through the water guide pipe at the bottom of the dehumidifier housing 2. Finally, the dehumidified air is discharged through the exhaust port 15 at the top, thus achieving the dehumidification treatment of the air inside the high-voltage cabinet 1.

[0025] Before use, the maximum humidity detection value of the upper humidity sensor 14 needs to be set. When the device is powered on, if the upper humidity sensor 14 detects that the humidity in the air reaches or exceeds this value, it will send a signal to the controller. The controller will then control the upper lift 13 to start, which will move the side plate 12 and the semiconductor plate 8. The semiconductor plate 8 will move to a position next to the upper plate 9 and the lower plate 10, thus merging the two together. At this time, the air drawn in by the suction fan 3 will be discharged from the outlet 7, passing through the S-shaped channel formed by the upper plate 9 and the lower plate 10, and coming into contact with the semiconductor plate 8. The water vapor in the air will condense into water at the cold end under the cooling effect of the semiconductor plate 8. The condensed water will be discharged from the cabinet 1 through the water guide pipe below the dehumidifier housing 2. At this time, because the S-shaped channel increases the residence time of the gas next to the semiconductor plate 8 compared to the original method of directly discharging from the gap between the upper plate 9 and the lower plate 10 and the semiconductor plate 8, the moisture treatment effect is ensured.

[0026] In summary, the above structural design allows for an extended airflow path within the dehumidifier housing 2. When the upper humidity sensor 14 detects high humidity in the intake air, it quickly controls the semiconductor plate 8 to contact the side walls of the upper plate 9 and lower plate 10. This causes the intake air to pass through an S-shaped path formed by the upper plate 9 and lower plate 10, increasing the time the air spends near the semiconductor plate 8 for dehumidification. If the humidity in the intake air decreases, the lifting device 13 will control the semiconductor plate 8 to reset, and the intake air will quickly pass through the gap between the upper plate 9, lower plate 10, and semiconductor plate 8. This ensures good dehumidification under different humidity conditions without the need for frequent adjustments to the exhaust fan speed.

[0027] Based on the above embodiments, it was found during use that although the processing time for moisture can be adjusted according to the humidity in the air, due to the high length of the high-voltage cabinet, if the suction position is fixed, it is impossible to suck in all the moisture in the cabinet 1 for processing, which is quite limited and will also affect the dehumidification effect in the cabinet 1. To solve the above problems, the above structure has been further improved.

[0028] The adjustment mechanism includes an adjustment frame 16. Support plates 17 are fixedly connected to both the upper and lower ends of the side wall of the fixed plate 4. Threaded rods 18 are rotatably connected between the support plates 17. A drive motor 19 is fixedly connected to the bottom end of one of the support plates 17. The output end of the drive motor 19 passes through the support plate 17 and is fixedly connected to the side end of the threaded rod 18. A drive block 20 is fixedly connected to the side wall of the adjustment frame 16. The threaded rod 18 is threadedly connected to the inner side wall of the drive block 20. A T-shaped rod 21 is slidably connected to the inner side of the adjustment frame 16. A suction head 22 is fixedly connected to the side wall of the T-shaped rod 21. The other end of the hose 5 is fixedly connected to the bottom end of the suction head 22. A secondary adjustment mechanism is also provided for further adjusting the position of the suction head 22 according to the humidity inside the cabinet 1.

[0029] A guide rod 23 is fixedly connected between the support plates 17, and the guide rod 23 is set through the inner wall of the drive block 20. By setting the guide rod 23, the guide function can be activated during the up and down movement of the drive block 20 driven by the threaded rod 18, so as to prevent the drive block 20 from rotating with the threaded rod 18 and improve the stability of the equipment during operation.

[0030] The auxiliary adjustment mechanism includes a lower lift 24 and a lower humidity sensor 25. Several lower humidity sensors 25 are provided and are fixedly connected at equal intervals to the inside of the cabinet 1. The lower lift 24 is fixedly connected to the side wall of the T-shaped rod 21. A circular hole is opened on the side wall of the T-shaped rod 21 relative to the lower lift 24. A circular rod 26 is slidably connected in the circular hole. The lower lift 24 is fixedly connected to the side wall of the circular rod 26. The side wall of the fixing plate 4 is provided with an upper right-angle plate 27 with an inclined surface relative to the lower humidity sensor 25. The side wall of the upper right-angle plate 27 is fixedly connected to the fixing plate 4 through a connecting block 28. The drive motor 19 is electrically connected to the lower lift 24 through a controller.

[0031] The T-shaped rod 21 is provided with a side end that penetrates the outer wall of the adjustment frame 16. Two pairs of return springs 29 are fixedly connected between the side wall of the T-shaped rod 21 and the inner side of the adjustment frame 16. With the setting of the return springs 29, when the round rod 26 is disengaged from the inclined surface of the upper right angle plate 27, the return springs 29 drive the T-shaped rod 21 to drive the suction head 22 to return to its original position.

[0032] The lower humidity sensor 25 is located below the component installation position inside the cabinet 1, and the lower humidity sensor 25 is electrically connected to the lower lift 24 through the controller.

[0033] A lower right-angle plate 30 with an inclined surface is fixedly connected between the upper right-angle plate 27 and the fixed plate 4. A groove 31 with a horizontal inclined surface of the lower right-angle plate 30 is opened through the side wall of the upper right-angle plate 27. A circular groove 32 is opened on the outer wall of the round rod 26. The width of the groove 31 is the same as the diameter of the circular groove 32 on the round rod 26. A photoelectric reflective sensor 33 is fixedly connected through the rear side of the T-shaped rod 21. Both the upper right-angle plate 27 and the lower right-angle plate 30 are made of reflective materials with high reflectivity and good optical properties, which can reflect the signal emitted by the photoelectric reflective sensor 33 back. The photoelectric reflective sensor 33 is electrically connected to the lower lifter 24 through the controller.

[0034] By setting up the photoelectric reflective sensor 33, when the T-shaped rod 21 is next to the upper right-angle plate 27 and the lower right-angle plate 30, the photoelectric reflective sensor 33 generates a signal that is reflected back through the upper right-angle plate 27 and the lower right-angle plate 30. Subsequently, the photoelectric reflective sensor 33 detects the reflected signal and transmits the signal to the controller. At this time, the controller will prevent the lower lift 24 from operating, thereby avoiding the lower humidity sensor 25 from detecting high humidity in the air when the T-shaped rod 21 is next to the upper right-angle plate 27 and the lower right-angle plate 30, and controlling the lower lift 24 to start, causing the round rod 26 to extend and collide with the side walls of the upper right-angle plate 27 and the lower right-angle plate 30.

[0035] Before use, the fixing plate 4 needs to be fixed inside the cabinet 1. Then, the upper right-angle plate 27 and the lower right-angle plate 30 are cut according to the size of the components inside the high-voltage cabinet to ensure that the inclined surfaces of the upper right-angle plate 27 and the lower right-angle plate 30 can squeeze the round rod 26 to move to the designated position, so as to avoid the side end of the T-shaped rod 21 from colliding with the components. Then, the maximum humidity detection value of the lower humidity sensor 25 needs to be set. After that, when the equipment is powered on, the drive motor 19 will drive the threaded rod 18 to rotate, which will drive the threaded drive block 20 to move upward, and at the same time drive the adjustment frame 16, the T-shaped rod 21 and the suction head 22 to move upward, so as to extract and dehumidify the air at different heights inside the cabinet 1. It should be noted that the suction head 22 is connected to the suction end of the suction fan 3 by a flexible hose 5, which can be bent at will, so as not to obstruct the up and down movement of the suction head 22.

[0036] During this process, when the humidity sensor 25 detects that the humidity in the air reaches or exceeds the specified value, it will transmit a signal to the controller. The controller will then control the lower lift 24 to start when it moves to the position next to the corresponding humidity sensor 25, causing the round rod 26 to extend from the side of the T-shaped rod 21 and move the round rod 26 to the position below the upper right-angle plate 27. Subsequently, when the drive motor 19 drives the round rod 26 to the lower side of the right-angle plate 27, since the round rod 26 and the T-shaped rod 21 can only slide laterally within the adjustment frame 16, the round rod 26 will be gradually squeezed towards the rear side of the cabinet 1 by the pressure of the upper right-angle plate 27. At the same time, the T-shaped rod 21 will slide within the adjustment frame 16 and gradually compress the return spring 29. Simultaneously, the suction head 22 will move towards the rear side of the cabinet 1, thereby drawing in the humid air from the rear side of the cabinet 1.

[0037] During this process, the round rod 26 will pass through the inclined groove 31 on the upper right-angle plate 27. However, the width of the inclined groove 31 is smaller than the diameter of the round rod 26. The diameter of the annular groove 32 on the round rod 26 is the same as the width of the inclined groove 31. Therefore, the round rod 26 will not get stuck in the inclined groove 31. Subsequently, the round rod 26 moves out from the inclined surface of the upper right-angle plate 27, thereby relieving the pressure on the round rod 26. Then, under the elastic force of the return spring 29, the T-shaped rod 21 is pushed to reset, and at the same time, the round rod 26 is reset. At this time, the lower lifter 24 will retract the round rod 26, so that the T-shaped rod 21 passes through the next upper right-angle plate 27. When the plate 27 is not squeezed or displaced, when the adjustment frame 16 moves up to the highest point of the cabinet 1, the drive motor 19 will reverse to drive the threaded rod 18 to reverse, thereby driving the drive block 20 to move downward, and at the same time driving the suction head 22 to move downward. At this time, the controller will transmit a signal to the lower lift 24, so that when the lower humidity sensor 25 controls the lower lift 24 to start, it can extend a further distance, so that the side end of the round rod 26 contacts the side wall of the fixed plate 4. When moving upward, the lower lift 24 does not receive a signal, and can only drive the round rod 26 to move to a position that is aligned with the side wall of the lower right angle plate 30.

[0038] During this process, if the humidity in the air behind the dehumidifier cabinet 1 exceeds the set value, the controller will also activate the lower lift 24 to extend the round rod 26 and move it above the lower right-angle plate 30. When the round rod 26 moves to the inclined surface of the lower right-angle plate 30, it will be squeezed by the inclined surface of the lower right-angle plate 30, causing the suction head 22 to gradually penetrate into the rear side of the cabinet 1. During this process, the circular groove 32 on the round rod 26 will be inserted into the inclined groove 31 to avoid obstructing the normal movement of the round rod 26. Then the round rod 26 slides out from the inclined surface of the lower right-angle plate 30, and the lower lift 24 controls the round rod 26 to reset, thus enabling the rearward suction operation when the suction head 22 moves down.

[0039] In summary, the above structural design not only enables the suction head 22 to move up and down to comprehensively extract and dehumidify the air inside the cabinet 1, but also allows the lower humidity sensor 25 to detect when the humidity in the rear of the cabinet 1 reaches a certain value, controlling the lower lifter 24 to extend the round rod 26. Under the pressure of the inclined surface of the upper right-angle plate 27, the suction head 22 moves towards the rear of the cabinet 1. This allows for flexible adjustment of the suction position of the suction head 22 according to the air humidity, enabling more precise suction treatment of humidity at different heights and positions, further improving dehumidification efficiency.
