[0001] The present invention relates to the technical field of arc protection equipment, in particular to an arc protection device for power distribution equipment. Background Art

[0002] Power distribution equipment, typically high-voltage distribution boxes, can experience arcing during operation, necessitating arc protection. Arc protection refers to the ability of the power system to prevent arcing due to various short-circuit conditions. With the continuous advancement of technology and the rapid progress of society, the power industry has also experienced rapid development, and the application of power distribution equipment has increased significantly. An arc protection device is a fast and reliable dedicated busbar protection system that utilizes a dual-criteria principle: arc detection and overcurrent detection. It features a simple principle, reliable and rapid operation, no special requirements for substation primary equipment, adaptability to various operating modes, and no need for switching protection in any operating mode. It is an ideal solution for busbar protection in power plants, substations, and industrial and commercial distribution systems. Arcing will persist as long as the system remains powered on. To minimize the hazards of arcing, arc protection devices are required to ensure safe use.

[0003] At present, after the arc protection device is installed on the power distribution equipment, a large number of optical fibers need to be connected and used, and the optical fibers need to be bundled together, which easily causes the optical fibers to become entangled with each other and cannot be arranged in an orderly manner, which is very easy to cause confusion and inconvenience for subsequent maintenance.

[0005] The top end of the elastic clamping tooth is pressed against the top of the elastic clamping tooth, so that the elastic clamping tooth is pressed against the top of the elastic clamping tooth and the top of the elastic clamping tooth is pressed inwardly, so that the elastic clamping tooth is elastically deformed and contacts with the optical fiber through the elastic partition, thereby elastically clamping and fixing the optical fiber, so that the optical fiber is not easily entangled with each other, and optical fiber disorder is avoided.

[0006] Preferably, there are five elastic clamping teeth, and the five elastic clamping teeth are evenly distributed on the bottom of the inner wall of the support frame.

[0008] Preferably, a threading assembly is installed on the side of the inner cavity of the frame, and the threading assembly is installed at a position close to the support frame. The threading assembly includes a straight hole and a conical sleeve. The straight hole is opened at the end of the frame away from the display screen, and the conical sleeve is fixedly installed on the outside of the frame and close to the straight hole. An arc-shaped spring piece is fixedly installed on the side of the inner cavity of the frame, and a rectangular frame is fixedly installed at the end of the arc-shaped spring piece away from the inner cavity of the frame. A conical rubber sleeve is fixedly installed in the middle of the outer side of the rectangular frame, and the middle of the inner cavity of the conical rubber sleeve is fixedly installed. A curved sealing ring is fixedly installed at the top, a guide rod is slidably installed at the middle of the top of the rectangular frame, and the guide rod is fixedly installed between the inner wall of the frame. The corresponding positions on the top of the rectangular frame are fixedly installed with pressure plates through brackets. The position of the pressure plate corresponds to the position of the rolling wheel. The optical fiber passes through the conical sleeve, the straight hole and the conical rubber sleeve in sequence. The conical sleeve is made of silicone material and can be elastically contracted so that the conical sleeve shrinks on the surface of the optical fiber, thereby performing a preliminary seal on the optical fiber part outside the frame to reduce the entry of debris into the frame.

[0009] When the connecting plate moves downward, and with the support of the supporting plate, the rolling wheel moves downward, and the rolling wheel can be used to move downward, so that the pressure plate is subjected to rolling pressure, and under the support and guidance of the guide rod, the rectangular frame drives the conical rubber sleeve to move to a position close to the straight hole, and the conical rubber sleeve and the curved sealing ring can be subjected to extrusion pressure, so that the conical rubber sleeve and the curved sealing ring can fit tightly with the optical fiber, and can be sealed again. Through multiple sealings, external dust and debris are not easily entered into the rack, and the interaction between the structures is fully utilized to connect the structures together.

[0010] Preferably, the curved sealing ring is made of rubber, the pressure plate is installed at an angle, there are two pressure plates, and the two pressure plates are installed symmetrically along the guide rod.

[0011] Preferably, a blower mechanism is installed on the side of the outer side of the frame, and the blower mechanism includes a rectangular shell and an auxiliary module. The rectangular shell is fixed to the side of the outer side of the frame by screws, and the auxiliary module is installed in the middle of the inside of the rectangular shell. A servo motor is fixedly installed on the side of the inside of the rectangular shell, and a rotating shaft is fixedly installed on the output end of the servo motor. A fan blade is fixedly installed on the end of the rotating shaft away from the servo motor, and a rubber rod is fixedly installed on the side of the outer side of the fan blade. An air inlet is provided on the side of the outer side of the rectangular shell. The output end of the servo motor is rotated to drive the rotating shaft to rotate, so that the fan blade rotates in a circle, and the rotating fan blade can be used to blow the air in the frame, so that the components inside the frame are dissipated by the flow of gas, and the heat can be dissipated in time, and high temperature is not likely to occur.

[0012] The outer edge of the dust filter screen is fixedly mounted on the middle of the inner cavity of the rectangular shell, and the rotating shaft is rotatably mounted on the center of the dust filter screen, and a connecting round rod is rotatably mounted on the side of the outer side of the dust filter screen, and a torque spring is fixedly mounted between the end surface of the outer side of the connecting round rod and the outer side of the dust filter screen, and the connecting round rod passes through the center of the torque spring, and the torque spring is mounted on a side close to the servo motor, and a scraper is fixedly mounted on the end of the connecting round rod away from the torque spring, so that the dust filter screen can be used to filter dust and debris carried in the air. At the same time, as the rubber rod is driven by the fan blades to rotate, the rubber rod in the fan rotation applies a pulling force to the scraper, and under the rotating connection of the connecting round rod, the scraper rotates to adjust the angle, and the torque spring is elastically deformed after being subjected to the torque force, so that the rotation of the scraper can be used to scrape off the dust and debris attached to the surface of the dust filter screen, thereby achieving a self-cleaning effect and not prone to clogging. As the rubber rod separates from the scraper, the scraper rotates in the opposite direction to reset under the elastic force provided by the torque spring.

[0013] Preferably, there are three connecting rods, and the three connecting rods are evenly distributed along the circumferential direction of the axis of the rotating shaft, and the outer edge of the scraper is in contact with the outer side of the dust filter.

[0014] Preferably, an air outlet assembly is installed at the side of the top of the frame, and the air outlet assembly includes a square cover shell, the square cover shell is fixedly installed at the side of the top of the frame, the square cover shell is communicated with the frame, a rectangular notch is opened at the corner of the top of the square cover shell, a block is fixedly installed inside the square cover shell, an air duct is opened in the middle of the block, a sealing ring is fixedly installed on the top of the block and near the air outlet of the air duct, and a cover plate is hinged at the side of the inner cavity of the square cover shell, when the gas is blown, the cover plate is subjected to the upward blowing force of the air flow, and the cover plate can be rotated counterclockwise to adjust the angle, so that the air outlet at the top of the air duct is opened, so that the air flow can be discharged through the air duct; When the fan blades stop rotating, the blowing force of the airflow on the cover disappears, and under the action of the cover's own gravity, the cover rotates clockwise to reset, which can press and seal the sealing ring and block the air outlet at the top of the air duct to reduce the entry of external debris.

[0015] Preferably, the sealing ring is made of rubber, and the cover plate is installed directly above the stop block.

[0016] The present invention provides an arc protection device for power distribution equipment. It has the following beneficial effects: 1. The arc protection device for the power distribution equipment passes the optical fiber through the middle of the elastic clamping teeth, so that the elastic partition separates the optical fiber inside the elastic clamping teeth, so that the optical fibers are arranged in an orderly manner. Combined with the specific elasticity of the elastic partition, the optical fibers are elastically supported, thereby elastically protecting the optical fibers and not easily causing damage to the optical fibers.

[0017] Second, the arc protection device for the power distribution equipment utilizes multiple sets of elastic clamping teeth evenly distributed at the bottom of the inner wall of the support frame, which can comb a large number of used optical fibers and avoid confusion, thus facilitating subsequent maintenance.

[0018] 3. The arc protection device for the power distribution equipment utilizes the wavy surface of the elastic partition to reduce the contact area between the optical fiber and the surface of the elastic partition, and utilizes the unevenness of the wavy surface to facilitate air to pass through the gap between the optical fiber and the elastic partition, thereby helping to promptly remove the heat generated by the optical fiber and thereby protecting the optical fiber.

[0019] 4. The arc protection device for the power distribution equipment is driven to move downward by the sliding connection of the strip sleeve, so that the herringbone pressure plate is stuck on the top of the elastic clamping teeth, so that the top of the elastic clamping teeth is subjected to extrusion force, which squeezes the top of the elastic clamping teeth inward, causing the elastic clamping teeth to elastically deform and contact with the optical fiber through the elastic partition, thereby elastically clamping and fixing the optical fiber, making it less likely for the optical fibers to be entangled with each other, avoiding optical fiber disorder.

[0020] 5. The arc protection device for the power distribution equipment uses the strip sliding sleeve to move downward, and under the elastic support of the zigzag spring strip, the semicircular clamping block moves downward, and uses the semicircular clamping block to be clamped in the position of the arc-shaped clamping groove. Under the elastic force of the zigzag spring strip, self-locking can be achieved, so that the connection between the structures is firm and not easy to loosen.

[0021] 6. The arc protection device for the power distribution equipment uses a conical sleeve made of silicone material, which can be elastically contracted so that the conical sleeve shrinks on the surface of the optical fiber, thereby preliminarily sealing the optical fiber part outside the rack and reducing the entry of debris into the rack.

[0022] 7. The arc protection device for the power distribution equipment, when the connecting plate moves downward, and under the support of the support plate, the rolling wheel moves downward, the rolling wheel can be used to move downward, so that the pressure plate is subjected to rolling pressure, and under the support and guidance of the guide rod, the rectangular frame drives the conical rubber sleeve to a position close to the I-shaped hole, so that the conical rubber sleeve and the curved sealing ring can be subjected to extrusion pressure, so that the conical rubber sleeve and the curved sealing ring can fit tightly with the optical fiber, and can be sealed again, through multiple sealing.

[0023] 8. The arc protection device used in the power distribution equipment utilizes the rotation of the servo motor output end to drive the shaft to rotate, thereby causing the fan blades to rotate in a circle. The rotating fan blades can be used to blow the air in the rack, thereby dissipating the heat to the components inside the rack through the flow of gas, which can dissipate the heat in time and prevent high temperature from occurring.

[0024] 9. The arc protection device for the power distribution equipment, as the rubber rod is driven by the fan blade to rotate, the rotating rubber rod of the fan applies a pushing force to the scraper, and under the rotating connection of the connecting round rod, the scraper rotates to adjust the angle, and the torque spring is elastically deformed after being subjected to the torque force, and the rotation of the scraper can be used to scrape off the dust and debris attached to the surface of the dust filter, thereby achieving a self-cleaning effect, and is not prone to clogging. As the rubber rod is separated from the scraper, and under the elastic force provided by the torque spring, the scraper rotates in the opposite direction to reset.

[0025] 10. The power distribution equipment uses an arc protection device. When the gas in the rack is blown, the cover is blown upward by the airflow, and the cover can be rotated counterclockwise to adjust the angle, so that the air outlet at the top of the air duct is opened, which facilitates the airflow to pass through the air duct and discharge. When the fan blades stop rotating, the blowing force of the airflow on the cover disappears, and under the action of the cover's own gravity, the cover is rotated clockwise to reset, which can press and seal the sealing ring and block the air outlet at the top of the air duct to reduce the entry of external debris.

A clamping assembly 35 is installed on the top of the support frame 31. The staff passes the optical fiber through the middle of the elastic clamping tooth 33, so that the elastic partition 34 separates the optical fiber inside the elastic clamping tooth 33, so that the optical fiber is arranged in order, and combined with the specific elasticity of the elastic partition 34, the optical fiber is elastically supported, thereby elastically protecting the optical fiber; By using multiple sets of elastic clamping teeth 33 evenly distributed on the bottom of the inner wall of the support frame 31, a large number of used optical fibers can be combed without causing confusion.

[0030] There are five elastic clamping teeth 33, and the five elastic clamping teeth 33 are evenly distributed at the bottom of the inner wall of the support frame 31. The outer side of the elastic partition 34 is a wavy surface, and the elastic partition 34 is evenly distributed on the corresponding two sides of the inner wall of the elastic clamping teeth 33. The surface of the elastic partition 34 is a wavy surface, so that the contact area between the optical fiber and the surface of the elastic partition 34 can be reduced, and the unevenness of the wavy surface is used to facilitate air to pass through the gap between the optical fiber and the elastic partition 34, which helps to promptly remove the heat generated by the optical fiber.

[0031] The clamping assembly 35 includes a strip sliding sleeve 351, which is slidably mounted on the top of the support frame 31, and a connecting plate 352 is fixedly mounted on the top of the strip sliding sleeve 351. A herringbone pressing plate 353 is fixedly mounted on the bottom of the connecting plate 352. The herringbone pressing plate 353 is mounted just above the elastic clamping teeth 33.

Under the sliding connection of the strip sleeve 351, the connecting plate 352 is driven to move downward, so that the herringbone pressure plate 353 is stuck on the top of the elastic clamping teeth 33, so that the top of the elastic clamping teeth 33 is subjected to an extrusion force, which squeezes the top of the elastic clamping teeth 33 inward, causing the elastic clamping teeth 33 to elastically deform and contact with the optical fiber through the elastic partition 34, thereby elastically clamping and fixing the optical fiber, making it less likely for the optical fibers to be entangled with each other.

[0032] The opening of the herringbone pressure plate 353 is downward, and the herringbone pressure plate 353 is evenly distributed at the bottom of the connecting plate 352.

The straight hole 41 is opened at the end of the frame 1 away from the display screen 2. The conical sleeve 42 is fixedly installed on the outside of the frame 1 and close to the straight hole 41. An arc-shaped spring piece 43 is fixedly installed on the side of the inner cavity of the frame 1. A rectangular frame 48 is fixedly installed on the end of the arc-shaped spring piece 43 away from the inner cavity of the frame 1.

The conical rubber sleeve 44 is fixedly installed in the middle of the inner cavity of the conical rubber sleeve A curved sealing ring 45 and a guide rod 46 are slidably installed in the middle of the top of the rectangular frame 48. The guide rod 46 is fixedly installed between the inner wall of the rack 1. The corresponding positions on the top of the rectangular frame 48 are fixedly installed with a pressure plate 47 through a bracket. The position of the pressure plate 47 corresponds to the position of the rolling wheel 357. The optical fiber is passed through the tapered sleeve 42, the straight hole 41 and the tapered rubber sleeve 44 in sequence. The tapered sleeve 42 is made of silicone material and can be elastically contracted so that the tapered sleeve 42 contracts on the surface of the optical fiber, thereby performing a preliminary seal on the optical fiber part outside the rack 1 to reduce the entry of debris into the rack 1.

[0034] The curved sealing ring 45 is made of rubber, and the pressure plate 47 is installed at an angle. There are two pressure plates 47, and the two pressure plates 47 are installed symmetrically along the guide rod 46. When the connecting plate 352 moves downward, and under the support of the support plate 356, the rolling wheel 357 moves downward, the rolling wheel 357 can be used to move downward, so that the pressure plate 47 is subjected to rolling pressure, and under the support and guidance of the guide rod 46, the rectangular frame 48 drives the conical rubber sleeve 44 to move to a position close to the straight hole 41, so that the conical rubber sleeve 44 and the curved sealing ring 45 can be subjected to extrusion pressure, so that the conical rubber sleeve 44 and the curved sealing ring 45 can fit tightly with the optical fiber, and can be sealed again. Through multiple sealing, external dust and debris are not easy to enter the frame 1.

[0035] The third embodiment, as Figure 7-10As shown, a blower mechanism 5 is installed on the side of the outer side of the rack 1, and the blower mechanism 5 includes a rectangular shell 51 and an auxiliary module 56.

A servo motor 52 is fixedly installed on the side of the inside of the rectangular shell 51, and a rotating shaft 53 is fixedly installed on the output end of the servo motor 52. A fan blade 54 is fixedly installed on the end of the rotating shaft 53 away from the servo motor 52, and a rubber rod 55 is fixedly installed on the side of the outer side of the fan blade 54. An air inlet 57 is provided on the side of the outer side of the rectangular shell 51. The staff turns on the servo motor 52 to work, and rotates the output end of the servo motor 52 to drive the rotating shaft 53 to rotate, so that the fan blade 54 rotates in a circle, and the rotating fan blade 54 can be used to blow the air in the rack 1, so that the components inside the rack 1 are cooled by the flow of gas, and the heat can be dissipated in time.

[0036] The auxiliary module 56 includes a dust filter 561. The outer edge of the dust filter 561 is fixedly installed in the middle of the inner cavity of the rectangular shell 51. The rotating shaft 53 is rotatably installed in the center of the dust filter 561. A connecting rod 562 is rotatably installed on the side of the outer side of the dust filter 561. A torque spring 563 is fixedly installed between the outer end surface of the connecting rod 562 and the outer side of the dust filter 561. The connecting rod 562 passes through the center of the torque spring 563. The torque spring 563 is installed on the side close to the servo motor 52. A scraper 564 is fixedly installed on the end of the connecting rod 562 away from the torque spring 563. When air enters the rectangular shell 51 through the air inlet 57, the dust filter 561 can be used to filter dust and debris carried in the air. At the same time, as the rubber rod 55 is driven by the fan blade 54 to rotate, the rotating rubber rod 55 applies a pulling force to the scraper 564, and under the rotation connection of the connecting rod 562, the scraper 564 rotates to adjust the angle, and the torque spring 563 is elastically deformed after being subjected to the torque force, so that the rotation of the scraper 564 can be used to scrape off the dust and debris attached to the surface of the dust filter 561, thereby achieving a self-cleaning effect and not prone to clogging; As the rubber rod 55 separates from the scraper 564 and under the elastic force provided by the torque spring 563, the scraper 564 rotates in the opposite direction to reset.

[0037] There are three connecting rods 562 , and the three connecting rods 562 are evenly distributed along the circumferential direction of the axis of the rotating shaft 53 . The outer edge of the scraper 564 is in contact with the outer side of the dust filter 561 .

A rectangular notch 62 is provided at the corner of the top of the square cover 61. A block 63 is fixedly installed inside the square cover 61. An air duct 64 is provided in the middle of the block 63. A sealing ring 65 is fixedly installed on the top of the block 63 and near the air outlet of the air duct 64. A cover plate 66 is hinged on the side of the inner cavity of the square cover 61. When the gas in the rack 1 is blown, the cover plate 66 is subjected to the upward blowing force of the air flow, and the cover plate 66 can be rotated counterclockwise to adjust the angle, so that the air outlet at the top of the air duct 64 is opened, so that the air flow can be discharged through the air duct 64.

[0039] The sealing ring 65 is made of rubber, and the cover plate 66 is installed just above the stop block 63. When the fan blades 54 stop rotating, the blowing force of the airflow on the cover plate 66 disappears, and under the action of the cover plate 66's own gravity, the cover plate 66 rotates clockwise to reset, so that the sealing ring 65 can be pressed and sealed, and the air outlet at the top of the air duct 64 can be blocked to reduce the entry of external debris.

[0040] When in use, the optical fiber is first passed through the tapered sleeve 42, the straight hole 41 and the tapered rubber sleeve 44 in sequence. The tapered sleeve 42 is made of silicone material and can be elastically contracted so that the tapered sleeve 42 is contracted on the surface of the optical fiber, thereby preliminarily sealing the optical fiber portion outside the rack 1 and reducing the entry of debris into the rack 1. The optical fiber is passed through the middle of the elastic clamping teeth 33, so that the elastic partition 34 separates the optical fiber inside the elastic clamping teeth 33, so that the optical fibers are arranged in an orderly manner. Combined with the specific elasticity of the elastic partition 34, the optical fibers are elastically supported, thereby elastically protecting the optical fibers. And by using multiple sets of elastic clamping teeth 33 evenly distributed on the bottom of the inner wall of the support frame 31, a large number of used optical fibers can be combed without causing confusion; And under the sliding connection of the strip sliding sleeve 351, the connecting plate 352 is driven to move downward, so that the herringbone pressure plate 353 is stuck on the top of the elastic clamping tooth 33, so that the top of the elastic clamping tooth 33 is subjected to an extrusion force, which squeezes the top of the elastic clamping tooth 33 inward, causing the elastic clamping tooth 33 to elastically deform and contact the optical fiber through the elastic partition 34, thereby elastically clamping and fixing the optical fiber, making it less likely for the optical fibers to be entangled with each other.

[0041] At the same time, the strip-shaped sliding sleeve 351 moves downward, and under the elastic support of the zigzag spring strip 354, the semicircular clamping block 355 moves downward, and the semicircular clamping block 355 is clamped in the position of the arc-shaped clamping groove 32. Under the elastic force of the zigzag spring strip 354, self-locking can be achieved, so that the connection between the structures is firm. When the connecting plate 352 moves downward, and supported by the supporting plate 356, the rolling wheel 357 moves downward, the rolling wheel 357 can be used to move downward, so that the pressure plate 47 is subjected to rolling force, and under the support and guidance of the guide rod 46, the rectangular frame 48 drives the conical rubber sleeve 44 to move to a position close to the straight hole 41, so that the conical rubber sleeve 44 and the curved sealing ring 45 are subjected to extrusion force, so that the conical rubber sleeve 44 and the curved sealing ring 45 can be tightly fitted with the optical fiber, and can be sealed again. Through multiple sealing, it is difficult for external dust and debris to enter the frame 1; The staff starts the servo motor 52 to work, and the output end of the servo motor 52 rotates, which drives the rotating shaft 53 to rotate, thereby causing the fan blades 54 to rotate in a circle. The rotating fan blades 54 can then be used to blow air inside the rack 1, thereby dissipating heat from the components inside the rack 1 through the flow of air, and dissipating heat in a timely manner; When air enters the rectangular housing 51 from the air inlet 57, the dust filter 561 can be used to filter the dust and debris carried in the air. As the rubber rod 55 is driven by the fan blade 54 to rotate, the rotating rubber rod 55 applies a pulling force to the scraper 564. Under the rotation connection of the connecting round rod 562, the scraper 564 rotates to adjust the angle. The torque spring 563 is elastically deformed after being subjected to the torque force. The rotation of the scraper 564 can be used to scrape off the dust and debris attached to the surface of the dust filter 561, thereby achieving a self-cleaning effect and not prone to clogging. As the rubber rod 55 separates from the scraper 564, the scraper 564 rotates in the opposite direction to reset under the elastic force provided by the torque spring 563. When the air in the rack 1 is blown, the cover 66 is blown upward by the airflow, and the cover 66 can be rotated counterclockwise to adjust the angle, so that the air outlet at the top of the air duct 64 is opened, facilitating the airflow to be discharged through the air duct 64.

[0042] When the fan blades 54 stop rotating, the blowing force of the airflow on the cover plate 66 disappears, and under the action of the cover plate 66's own gravity, the cover plate 66 rotates clockwise to reset, so that the sealing ring 65 can be pressed and sealed, and the air outlet at the top of the air duct 64 can be blocked to reduce the entry of external debris.
