Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a double-circuit low-voltage insulating bus duct. Background Art

[0002] Double-circuit low-voltage insulated bus duct is a closed conductive system used to transport large currents and distribute power. It has the characteristics of large current capacity, high safety factor, low construction and operation cost, flexible distribution, convenient maintenance and space saving. Bus duct is widely used in factories, commercial buildings, hospitals, airports, subway stations and other places for power distribution and transmission to meet high current requirements and improve distribution efficiency.

[0003] Double-circuit low-voltage insulated bus duct plays a core role in wind power generation systems, and its working condition is crucial to the safety of the unit. Since wind towers are subject to variable wind energy impacts during operation, causing vibrations, this continuous vibration may loosen the bus duct connections, thereby increasing contact resistance, abnormal heating, and even damaging the insulation layer of the bus duct, causing failures. If not discovered and handled in time, it may lead to major safety accidents. Traditional regular maintenance and manual maintenance methods are inadequate in this situation. Wind turbines are mostly located in remote areas, and maintenance is difficult, labor-intensive, and difficult to detect problems in real time and accurately. This lag not only affects the reliability of power transmission, but may also result in high maintenance costs after a failure occurs. More seriously, power generation interruptions caused by equipment damage will cause greater economic losses.

[0004] In response to the above problems, the prior art provides some solutions, such as patent application number: CN201921542891.8, which provides a bus duct connector. This solution allows the conductor to slide along the insulating rod. During the operation of the connector, if vibration occurs, the conductor will be displaced along with the conductor under the action of the conductor, so that the conductors can fit more closely and there will be almost no mutual displacement, reducing the possibility of gaps between the conductors, making the connection between the bus ducts more stable. However, this solution ensures the fit with the conductor by elastic deformation of the conductor during vibration. Therefore, under long-term vibration, the conductor will produce metal fatigue, resulting in a decrease in its own elasticity and a risk of breakage, which in turn causes damage to the bus duct. Summary of the invention

[0005] The purpose of the present invention is to provide a double-circuit low-voltage insulated bus duct to solve the problem that vibration causes the bus duct connection to loosen, thereby causing increased contact resistance, abnormal heating, and even damage to the insulation layer of the bus duct, causing failures. If not discovered and handled in time, it may lead to major safety accidents.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A double-circuit low-voltage insulated bus duct comprises an outer shell and a conductive bar, wherein the conductive bar is fixedly connected inside the outer shell, and two ends of the conductive bar extend to two sides of the outer shell respectively, and one end of the conductive bar is fixedly connected to a connector, and two sides of the connector are fixedly connected to side plates by reinforcing bolts, and two mounting seats are provided on the outer shell, and reinforcement components with clamping blocks and right driving sliders are provided on the two mounting seats, and the number of the clamping blocks is 2, and the two clamping blocks are slidably connected to the mounting seats, and the two clamping blocks are in contact with the side plates on the connectors respectively, and the right driving slider is slidably connected inside the mounting seat, and the reinforcement component is used to make the right driving slider slide when the double-circuit low-voltage insulated bus duct vibrates, thereby driving the clamping block to move toward the side plate, and a locking component is also provided inside the mounting seat, and the locking component is used to limit the movement of the clamping block in a direction away from the side plate.

[0008] It is easy to understand that the design sets a reinforcement component inside the mounting base. When the double-circuit low-voltage insulated bus duct is vibrated, the right drive slider inside the mounting base will move in the direction of the vibration. A clamping block is also provided on the mounting base. When the right drive slider moves, the reinforcement component will drive the clamping block to apply pressure to the side plates on both sides of the connector. At this time, the connection between the double-circuit low-voltage insulated bus duct and the connector is more stable. Therefore, the design can reinforce the connection between the double-circuit low-voltage insulated bus duct and the connector by utilizing vibration, ensuring that no gap is generated between the bus duct and the connector. , which improves the stability of power transmission, and the design does not require the addition of additional power devices, thus saving the production cost of the bus duct. The design also provides a locking assembly inside the mounting base. When the reinforcement assembly drives the clamping block to apply pressure to the side plate, the locking assembly can limit the movement of the clamping block away from the side plate, thereby enabling the clamping block to maintain pressure on the side plate, thereby avoiding the loosening of the bus duct and the connector due to the inability of the clamping block to maintain pressure on the side plate during and after vibration. Therefore, the design further improves the stability of the connection between the bus duct and the connector.

[0009] The two wheels are connected with each other through the guide rail, and the two wheels are connected with each other through the guide rail, and the two wheels are connected with each other through the guide rail.

[0010] It is easy to understand that when the bus duct is subjected to vibration, the right driving slider on the guide rail slides in the direction of the vibration. At this time, the driving racks 1 on both sides of the right driving slider drive the driving gears 1 on both sides to rotate, causing the rotating shaft 1 to rotate, and then driving the transmission gear 1 to rotate. Since the transmission gear 1 is engaged with the clamping rack on the sliding rod, the sliding rod will move, and the clamping block will move with the sliding rod. At this time, the clamping block applies pressure to the side plate. When the vibration stops, the reset spring 1 pushes the right driving slider to reset. At this time, the driving racks 2 on both sides of the right driving slider drive the driving gears 1 on both sides to rotate, but due to the action of the one-way bearing, the driving gear 1 will not drive the rotating shaft 1 to rotate. Therefore, this design can utilize the displacement generated by the right driving slider during vibration to ensure the fit between the bus duct and the connector. The design structure is simple and compact, does not require the setting of an additional power device, and saves manufacturing costs.

[0011] Preferably, the locking assembly includes a claw, a rectangular groove 1 is provided on the sliding rod, the claw is hinged inside the rectangular groove 1, a torsion spring is provided at the hinge between the claw and the sliding rod, a rectangular groove 2 is provided inside the mounting seat, a locking slider is slidably connected inside the rectangular groove 2, a ratchet is provided on the locking slider, a reset spring 3 is provided between the locking slider and the inner wall of the rectangular groove 2, the claw contacts the ratchet on the locking slider, a pressing block is also slidably connected to the mounting seat, and the pressing block is fixedly connected to the locking slider.

[0012] It is easy to understand that when the sliding rod drives the clamping block to apply pressure to the side plate, the claw inside the rectangular groove one moves with the sliding rod, and at this time the claw contacts the ratchet on the locking slider and rotates, and the sliding rod can move normally. If the sliding rod drives the clamping block to move in the direction away from the side plate, the claw contacts the ratchet and rotates in the other direction, but the claw will contact the inner wall of the rectangular groove one and cannot continue to rotate. At this time, the sliding rod cannot move. Therefore, this design can make the clamping block move only in the direction of the side plate, which makes it possible for the clamping block to apply pressure to the side plate to keep the bus duct and the connector in fit under any circumstances, thereby improving the stability of the connection between the bus duct and the connector. In addition, a pressing block is provided on the mounting seat of the design. When the staff dismantles the bus duct, the locking slider can be moved by directly pressing the pressing block to move the ratchet away from the claw. Therefore, this design facilitates the disassembly of the bus duct by the staff during maintenance and improves work efficiency.

[0013] Preferably, the guide rail is also slidably connected with a left driving slider, and a rotating shaft 2 is provided on both sides of the left driving slider, and the rotating shaft 2 is rotatably connected to the mounting seat, and a driving gear 2 is rotatably connected to the two rotating shafts, and a one-way bearing is provided between the driving gear 2 and the rotating shaft 2, and a driving rack 2 is provided on both sides of the left driving slider, and the driving gear 2 is meshed with the driving rack 2. A transmission gear 2 is also fixedly connected to the rotating shaft 2, and the transmission gear 2 is meshed with a clamping rack, and a reset spring 2 is provided between the left driving slider and the guide rail. When the left driving slider moves in a direction away from the sliding rod, the driving gear 2 drives the rotating shaft 2 to rotate and then drives the transmission gear 2 to rotate. When the left driving slider moves in the direction where the sliding rod is located, the driving gear 2 will not drive the rotating shaft 2 to rotate.

[0014] It is easy to understand that when vibration occurs, the bus duct will usually rock back and forth after being vibrated, but the right driving slider inside the reinforcement component can only drive the clamping block to apply pressure to the side plate when it slides in one direction. When it moves in the other direction, it will not drive the clamping block to apply pressure to the side plate. The design is to provide a left driving slider on the guide rail. When the left driving slider is moved by vibration, the driving racks 2 on both sides of the left driving slider drive the driving gears 2 on both sides to rotate, so that the rotating shaft 2 rotates, and then drives the transmission gear 2 to rotate. Since the transmission gear 2 is meshed with the clamping rack on the sliding rod, the sliding rod will move, and the clamping block will follow the sliding rod. The movable rod moves, and the clamping block applies pressure to the side plate. When the vibration stops, the reset spring 2 pushes the right driving slider to reset. At this time, the driving racks 2 on both sides of the left driving slider drive the driving gears 2 on both sides to rotate. However, due to the effect of the one-way bearing, the driving gear 2 will not drive the rotating shaft 2 to rotate. In this setting, when the left driving slider moves in one direction, the clamping block will move, and when the right driving slider moves in another direction, the clamping block will also move. Therefore, this design makes it possible for the sliders in both directions to reinforce the connection between the bus duct and the connector when the vibration causes the bus duct to shake in two directions, thereby improving the reinforcement effect of the reinforcement component.

[0015] Preferably, a blocking block is provided on the guide rail, the blocking block is fixedly connected to the guide rail, and buffer pads are provided on both sides of the blocking block, and the buffer pads on both sides of the blocking block are in contact with the left driving slider and the right driving slider respectively.

[0016] It is easy to understand that the design sets a blocking block on the guide rail. When the right driving slider or the left driving slider moves in one direction to move the clamping block, the other slider will contact the blocking block and cannot move. Therefore, the design avoids the situation where one of the right driving slider or the left driving slider is working while the other slider does not move, thereby avoiding the right driving slider and the left driving slider from affecting each other when working. Therefore, the design improves the stability of the reinforcement assembly.

[0017] Preferably, slide grooves are provided on both sides of the shell, and the two mounting seats are slidably connected to the two slide grooves respectively. Grooves are also provided on both sides of the shell, and the edges of the grooves are chamfered. The clamping block is located in the groove, and the clamping block is in contact with the inner wall of the groove. When the edge of the mounting seat is in contact with the side wall of the slide groove, the plane of the mounting seat close to the connector is flush with the plane of the shell close to the connector.

[0018] It is easy to understand that the design opens slide grooves on both sides of the shell. When the bus duct needs to be disassembled, the staff can unlock the clamping block by pressing the pressing block on the mounting seat, and then directly slide the mounting seat to make the mounting seat completely retracted into the slide groove, and can also press the clamping block to make the clamping block fit with the inner wall of the groove to fix the mounting seat to the shell. At this time, the bus duct and the connector will not be affected by the mounting seat when they are disassembled. Therefore, the design further facilitates the staff to disassemble and install the bus duct, improves work efficiency, and when the mounting seat is retracted into the slide groove, it can also reduce the footprint of the bus duct, facilitate the transportation and storage of the bus duct, and also avoid damage to the mounting seat caused by bumps during transportation of the bus duct, thereby increasing the service life of the bus duct.

[0019] Preferably, the length of the conductive bar extending out of the outer shell is A, the length of the contact portion between the conductive bar and the connection is B, the distance between the middle of the clamping block and the shell is C, and C=A-1 / 2B.

[0020] It is easy to understand that the design limits the length of the conductive bar extending out of the outer side of the shell and the length of the contact portion between the conductive bar and the connection, so that when the mounting seat moves to the outside of the slide slot and the clamping block applies pressure to the side plate on the connector, the position of the clamping block is located in the middle of the contact surface between the conductive bar and the connector. Therefore, the design avoids the clamping distance of the clamping block being too long or too short, which in turn causes insufficient pressure from the clamping block on one end of the conductive bar or the connector. The design enables the clamping block to be clamped in the middle of the contact surface between the conductive bar and the connector, so that the conductive bar and the connector are evenly stressed, thereby improving the reinforcement effect of the reinforcement component.

[0021] Preferably, positioning blocks are provided on both sides of the shell, the positioning blocks are fixedly connected to the shell, and the positioning blocks are in contact with the connector.

[0022] It is easy to understand that when the staff installs the bus duct, they need to use measuring tools to measure the bus duct to ensure that the installation seat of the bus duct is accurate. This design sets positioning blocks on both sides of the outer shell. When the staff installs the bus duct, as long as the positioning blocks on the outer shell touch the connector, the bus duct is in the best installation position. At this time, the clamping block is located in the middle of the contact surface between the conductive bar and the connector. Therefore, this design saves the measurement steps during the installation of the bus duct and improves the work efficiency of the staff.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention arranges a reinforcement component inside the mounting seat. When the bus duct is vibrated, the right driving slider will move in the direction of the vibration. When the right driving slider moves, the reinforcement component will drive the clamping block to apply pressure to the side plates on both sides of the connector. At this time, the connection between the bus duct and the connector is more stable. Therefore, the design can reinforce the connection between the bus duct and the connector by utilizing vibration, ensuring that no gap is generated between the bus duct and the connector, improving the stability of power transmission, and the design does not require the addition of an additional power device, thereby saving the production cost of the bus duct.

[0025] 2. The present invention provides a locking assembly inside the mounting base. When the reinforcement assembly drives the clamping block to apply pressure to the side plate, the locking assembly can limit the movement of the clamping block in the direction away from the side plate, thereby enabling the clamping block to maintain pressure on the side plate. This avoids the situation in which the clamping block cannot maintain pressure on the side plate during and after vibration, causing the bus duct and the connector to loosen. This design further improves the stability of the connection between the bus duct and the connector.

[0026] 3. The present invention arranges a left driving slider inside the mounting seat. When the left driving slider moves in one direction, the clamping block will move, and when the right driving slider moves in another direction, the clamping block will also move. Therefore, this design enables the sliders in both directions to reinforce the connection between the bus duct and the connector when the bus duct is shaken in two directions due to vibration, thereby improving the reinforcement effect of the reinforcement component.

[0040] See also Figures 1 to 8 When the staff installs the double-circuit low-voltage insulating bus duct, the staff inserts the conductive bar 2 at one end of the double-circuit low-voltage insulating bus duct into the connector 3, and the positioning block 34 on the shell 1 contacts the connector 3.
