Description

Technical Field

[0001] This utility model relates to the field of automatic tracking and compensation technology for arc suppression coils, and in particular to an automatic tracking and compensation device for arc suppression coils. Background Technology

[0002] An automatic tracking compensation arc suppression coil device is a type of equipment used in power systems. It can automatically and in real-time track and compensate for the capacitive current of the power grid to effectively handle single-phase grounding faults. When a single-phase grounding fault occurs in the power grid, a capacitive fault current is generated. The arc suppression coil provides inductive current to compensate for this, reducing the fault current to a very small level. This helps prevent reignition of the arc after it crosses zero, thus achieving the purpose of arc extinguishing. The automatic tracking compensation arc suppression coil device can automatically adjust the inductance value of the arc suppression coil according to changes in the capacitive current of the power grid, ensuring that the compensation current always matches the capacitive current, thereby guaranteeing the compensation effect. During the operation of the arc suppression coil device, components such as the arc suppression coil and the damping resistor box generate a significant amount of heat. When adjusting the speed of the adjustable-turn arc suppression coil, a certain amount of energy is lost and converted into heat. If heat is not dissipated in time, the equipment temperature will rise, affecting its performance and lifespan. Therefore, an automatic tracking compensation arc suppression coil device is needed.

[0003] Existing automatic tracking compensation arc suppression coil devices have limited heat dissipation range during use, and can only achieve local heat dissipation. They cannot fully cover the core components such as the arc suppression coil and damping resistor box that generate a lot of heat inside the device, which can easily lead to excessively high local temperatures. The replacement process of heat dissipation components is complicated and inconvenient to operate, which not only increases maintenance time and costs.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN221929090U, which discloses an automatic tracking compensation device for arc suppression coils. The patent describes a device that "includes a cabinet with an external protective shell. The outer surface of the protective shell has two symmetrical heat dissipation vents, each containing a dust filter. The protective shell also contains two symmetrical first mounting mechanisms. A set of support plates is fixedly connected inside the cabinet, and a cooling fan is fixedly connected to the inner top wall of the protective shell. This device, with its dust filter, first mounting mechanisms, and heat dissipation vents, allows for quick removal of the dust filter during use. This solves the problem in existing devices where the two dust filters are fixedly embedded inside the protective cover and the cylinder, making removal difficult and facilitating cleaning of the dust filter." While this method provides heat dissipation, it is only localized, resulting in inadequate cooling. Furthermore, long-term fan maintenance and replacement are cumbersome.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

In use, the existing automatic tracking compensation arc suppression coil devices have a limited heat dissipation range and can only achieve local heat dissipation. They cannot fully cover the core components such as the arc suppression coil and damping resistor box that generate a lot of heat, which can easily lead to excessively high local temperatures. The replacement process of heat dissipation components is complicated and inconvenient to operate, which not only increases maintenance time and cost.

[0008] The cooling mechanism includes a first bearing seat, which is connected to the upper surface of the fixed block. A ball screw is connected through one side surface of the first bearing seat. A second bearing seat is fitted onto the outer surface of the ball screw. A driven drive shaft is connected to one end surface of the ball screw. A first dual-shaft linkage belt is fitted onto the outer surface of the driven drive shaft. A drive main shaft is fitted onto the inner surface of the first dual-shaft linkage belt. A second dual-shaft linkage belt is fitted onto the outer surface of the drive main shaft. A drive drive shaft is provided on one side surface of the second dual-shaft linkage belt. An output shaft is connected to the inner surface of the drive drive shaft. A threaded rod slider is threadedly connected to the outer surface of the ball screw. A connecting plate is connected to one side surface of the threaded rod slider. A frame is provided on one side surface of the threaded rod slider.

[0009] Preferably, the inner wall of the cabinet is connected to a second bearing seat, and a fixing rod is rotatably connected to the upper surface of the second bearing seat.

[0010] Preferably, the driven drive shaft is provided in two sets and is connected to the outer surfaces of the ball screw and the fixed rod respectively by a first dual-shaft linkage belt.

[0011] Preferably, the outer surface of the fixed rod is connected to a driven transmission shaft and a transmission main shaft respectively.

[0012] Preferably, the first bearing housing and the second bearing housing are simultaneously connected by a guide shaft, and the outer surfaces of the ball screw and the guide shaft are simultaneously fitted with threaded rod sliders.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This automatic tracking compensation arc suppression coil device allows operators to open the cabinet door and pull out the support plate, which in turn moves the guide roller slider. After installing the compensation arc suppression coil, the support plate is pushed along the T-shaped guide groove into the placement cabinet. The entire installation process requires no complicated tools and is easy to operate. When the compensation arc suppression coil generates high temperatures during use, the first drive motor is started. The motor then drives the ball screw and fixed rod to rotate through the output shaft, drive transmission shaft, and belt, causing the threaded rod slider to slide along the guide optical axis, which in turn raises and lowers the frame. At the same time, the second drive motor is started to drive the impeller to generate airflow, which cools the inside of the placement cabinet. The hot air is dissipated through the heat dissipation holes. Finally, the design of simultaneous lifting and lowering on both sides greatly improves the cooling effect and ensures that the compensation arc suppression coil operates stably at a suitable temperature.

[0020] 2. With this automatic tracking compensation arc suppression coil device, when the second drive motor inside the frame needs maintenance or the protective net needs cleaning, the staff only needs to press the pressure block so that the pressure block squeezes the spring completely into the placement slot and disengages from the slot, and the frame can be directly removed to maintain the second drive motor or clean the protective net without disassembling the complex transmission structure, thus simplifying the maintenance process.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: an automatic tracking compensation arc suppression coil device, including a placement cabinet 1, a cabinet door 2 rotatably connected to one side surface of the placement cabinet 1, a fixing block 3 fixedly connected to the inner surface of the placement cabinet 1, a cooling mechanism 4 provided inside the placement cabinet 1, and an installation component 5 provided inside the placement cabinet 1.

[0029] The cooling mechanism 4 includes a first bearing seat 401. The upper surface of the fixing block 3 is connected to the first bearing seat 401. A ball screw 402 is connected through one side surface of the first bearing seat 401. A second bearing seat 403 is sleeved on the outer surface of the ball screw 402. A driven drive shaft 405 is connected to one end surface of the ball screw 402. A first dual-shaft linkage belt 406 is sleeved on the outer surface of the driven drive shaft 405. A drive main shaft 408 is sleeved on the inner surface of the first dual-shaft linkage belt 406. A drive main shaft 408 is sleeved on the outer surface of the drive main shaft 408. A second dual-axis linkage belt 409 has a drive transmission shaft 410 on one side surface. An output shaft 411 is connected to the inner side surface of the drive transmission shaft 410. A threaded rod slider 412 is threadedly connected to the outer side surface of the ball screw 402. A connecting plate 416 is connected to one side surface of the threaded rod slider 412. A frame 417 is provided on one side surface of the threaded rod slider 412. A second drive motor 419 is fixedly connected to the inner side surface of the frame 417. An impeller 420 is connected to the output end of the second drive motor 419.

[0030] Furthermore, the inner wall of the cabinet 1 is connected to a second bearing seat 403. The upper surface of the second bearing seat 403 is rotatably connected to a fixing rod 407. Through the setting of the fixing rod 407, a symmetrical support structure can be formed with the ball screw 402. Both of them are connected to the driven transmission shaft 405 through the first double-axis linkage belt 406 on their outer sides, and can synchronously receive the power transmitted by the transmission main shaft 408, ensuring that the sliders 412 of the threaded rods on both sides maintain the same speed when they rise and fall along the guide optical axis 404.

[0031] Furthermore, the driven transmission shaft 405 is provided with two sets, which are respectively connected to the outer surfaces of the ball screw 402 and the fixed rod 407 via the first double-shaft linkage belt 406. Through the setting of the first double-shaft linkage belt 406, the power of the transmission main shaft 408 can be synchronously transmitted to the ball screw 402 and the fixed rod 407, ensuring that the two maintain the same speed when rotating.

[0032] Furthermore, the outer surface of the fixed rod 407 is connected to the driven drive shaft 405 and the main drive shaft 408 respectively. Through the setting of the main drive shaft 408, it can receive the power transmitted by the drive drive shaft 410 through the second double shaft linkage belt 409, and distribute the power synchronously to the two sets of driven drive shafts 405, so as to ensure that the ball screws 402 on both sides and the fixed rod 407 can start at the same time.

[0033] Furthermore, the first bearing housing 401 and the second bearing housing 403 are simultaneously connected by a guide shaft 404. The outer surfaces of the ball screw 402 and the guide shaft 404 are simultaneously fitted with threaded rod sliders 412. Through the setting of the threaded rod sliders 412, the connecting bridge between the ball screw 402 and the frame 417 can accurately convert the rotational motion of the ball screw 402 into its own linear motion, thereby driving the frame 417 and the impeller 420 to rise and fall stably, and realize the cooling of different height areas inside the cabinet 1.

[0034] Furthermore, a first drive motor 413 is connected to one end of the output shaft 411. The first drive motor 413 is threadedly connected to the upper surface of the placement cabinet 1. Through the setting of the first drive motor 413, the output shaft 411 can stably output torque, drive the drive transmission shaft 410 to rotate, and then transmit the power synchronously to the two sets of transmission main shafts 408 through the belt transmission structure, ensuring that the ball screws 402 on both sides and the fixed rod 407 rotate synchronously.

[0035] Furthermore, a frame 417 is welded to one side surface of the threaded rod slider 412, and a protective net 418 is connected to both sides of the frame 417. The protective net 418 prevents workers from accidentally touching the high-speed rotating impeller 420 when inspecting the placement cabinet 1 or taking out the compensation arc suppression ring 10, thereby reducing the risk of operational safety.

[0036] Furthermore, inspection doors 414 are rotatably connected to both sides of the cabinet 1, and a handle 415 is fixedly connected to one side of the inspection door 414. With the setting of the inspection door 414, the staff can quickly open the inspection door 414 through the handle 415 and directly access the faulty parts without disassembling the entire cabinet, which greatly shortens the maintenance time.

[0037] Furthermore, a mounting component 5 is provided on one side surface of the frame 417, and placement grooves 501 are provided on both sides of the frame 417. A spring 502 is connected to the inner surface of the placement groove 501, and a guide limiting rod 503 is connected to the inner surface of the placement groove 501. A slot 504 is provided through one side surface of the connecting plate 416. A pressure block 505 is connected to one end surface of the spring 502, and the pressure block 505 is sleeved on the outer surface of the guide limiting rod 503. Through the setting of the spring 502, a continuous elastic thrust can be provided to the pressure block 505. When the frame 417 and the connecting plate 416 are assembled, the spring 502 can automatically push the pressure block 505 into the slot 504, and the two can be quickly fixed without additional tools, simplifying the installation process.

[0038] Furthermore, heat dissipation holes 6 are opened on both sides of the cabinet 1, and a T-shaped guide groove 7 is opened on the inner side of the fixing block 3. A guide roller slider 8 is set on the inner surface of the T-shaped guide groove 7. A bearing plate 9 is fixedly connected to one side surface of the guide roller slider 8. A compensation arc suppression ring 10 is installed on the top of the bearing plate 9. By setting the guide roller slider 8, the sliding friction between the bearing plate 9 and the T-shaped guide groove 7 can be converted into rolling friction, which greatly reduces the resistance when the bearing plate 9 is pulled out or pushed in, allowing the staff to operate easily without effort. In particular, after placing the compensation arc suppression ring 10 on the bearing plate 9, the pushing and pulling process can still be guaranteed to be smooth.

[0039] Working principle: First, the operator opens cabinet door 2 and pulls out the support plate 9. The support plate 9 then pulls out the guide roller slider 8. Next, the compensation arc suppression ring 10 is installed. Then, the support plate 9, along with the guide roller slider 8, slides into the placement cabinet 1 within the T-shaped guide groove 7. When the compensation arc suppression ring 10 is in use, it generates high temperature, activating the first drive motor 413. The first drive motor 413 then drives the drive transmission shaft 410 to rotate via the output shaft 411. When the drive transmission shaft 410 rotates, it drives two sets of transmission main shafts 408 to rotate via two sets of second double-shaft linkage belts 409. When the transmission main shafts 408 rotate, they drive two sets of driven transmission shafts 405 to rotate via the first double-shaft linkage belt 406. When the driven transmission shafts 405 rotate, they drive... The ball screw 402 rotates synchronously with the fixed rod 407. When the ball screw 402 rotates, it drives the threaded rod slider 412 to slide along the guide optical axis 404, which in turn drives the frame 417 to rise and fall. Then, the second drive motor 419 is started, which drives the impeller 420 to move. The impeller 420 generates airflow to cool the inside of the placement cabinet 1. At the same time, the hot air inside can also be dissipated from the heat dissipation hole 6. When the second drive motor 419 inside the frame 417 needs maintenance, the pressure block 505 can be pressed. When the pressure block 505 squeezes the spring 502 from the slot 504 and fully enters the placement slot 501, the frame 417 can be removed to maintain the second drive motor 419 and clean the protective net 418. This simultaneous lifting and lowering of both sides greatly improves the cooling effect.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
