Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution, and in particular relates to an interlocking mechanism, a bus duct plug-in box and a bus duct system. Background Art

[0002] As a key component of the bus duct system to distribute electrical energy to various electrical equipment, the design and function of the bus duct plug-in box are crucial to ensure the stability and safety of the entire power supply system. However, there are some design defects in the bus duct plug-in boxes currently on the market, which may have an adverse effect on the normal operation and safety of the system.

[0003] At present, the plug-in connection and separation positions of the bus duct plug-in box and its locking and unlocking mechanism are independent of each other, and no effective interlocking mechanism has been formed. This design deficiency means that even if the plug-in is in the connection position, the plug-in box can still be installed on the bus duct and can be locked or unlocked, or even removed from the bus duct. Such operation may not only cause damage to the bus duct plug-in box and bus duct equipment, but may also cause the bus duct system to fail to operate normally and be unable to supply power to the back-end equipment. In extreme cases, such improper operation may even cause personal injury.

[0004] For large data centers, any form of power outage may cause huge economic losses, and its severity cannot be ignored. At the same time, protecting the lives of personnel is the most important consideration in product design. Therefore, the safety and reliability of the bus duct plug-in box play a vital role in preventing economic losses and protecting personnel safety.

[0005] In summary, the bus duct junction box in the existing technology has obvious design defects, and it is urgent to solve these problems through technological innovation to improve the stability and safety of the power supply system and meet the high requirements of key application scenarios such as modern data centers.

When installing or removing the bus duct plug-in box, the grounding protection guide rail 200 is first connected to the bus duct and then separated to ensure the continuity of the grounding protection during the operation.

[0081] Specifically, the interlocking mechanism 200 includes a grounding protection rail 600, an interlocking mechanism fixed member 110 and an interlocking mechanism moving member. Fig.17 and Fig.18 As shown, the grounding protection rail 600 is used to be detachably connected to the bus duct 20, and the grounding protection rail 600 is installed on the housing 100.

When the bus duct plug-in box 10 is installed, the plug-in unit 500 must be in a separated position, otherwise the operating component 210 of the interlocking mechanism 200 cannot be operated, that is, the bus duct plug-in box 10 cannot be installed on the bus duct 20. When the bus duct plug-in box 10 is removed from the bus duct 20, the plug-in unit 500 must be placed in a separated position first, otherwise the operating component 210 of the interlocking mechanism 200 cannot be operated, that is, the bus duct plug-in box 10 cannot be removed from the bus duct 20.

The number of the plug-in holes 111 can be the same as the number of plug-ins of the plug-in unit 500, or can be more than the number of plug-ins of the plug-in unit 500.

[0089] In a preferred embodiment of the present application, Figure 3 As shown, the bus duct plug-in box 10 may include only one socket output unit 730, or may include multiple socket output units 730 (and the number of switches of the main circuit unit 710 will also increase accordingly), and the number of switches of the socket output unit 730 may be flexibly configured according to actual needs.

The communication transmission unit 740 can be connected and mounted on the side plate 150 by bolts, threaded connections, snap connections, mortises, plug connections, snap connections, pasting, riveting, key connections, pin connections, crimping, etc. When the bus duct plug-in box 10 of the utility model is removed from the bus duct 20, it is only necessary to remove the communication transmission unit 740 from the side plate 150 or remove the side plate 150 together with the communication transmission unit 740 and suspend them in the air, so as to ensure that the bus duct system communication does not drop, and the product has higher reliability.

[0091] The plug-in unit 500 is movably disposed in the plug-in hole 111, that is, the plug-in unit 500 can reciprocate along the path between the interlocking mechanism fixed member 110 and the top plate 160.

The fixed column 310 is fixedly connected to the rotating portion 330 and is disposed in the fixed portion 320 or the side plate 150. That is, when the rotating portion 330 is rotated, the fixed column 310 can be driven to move in the fixed portion 320 or the side plate 150.

[0094] In another embodiment of the present application, Figure 7 and Figure 8As shown, the bus duct plug-in box 10 further includes a transmission mechanism 400. The input end of the transmission mechanism 400 is connected to the output end of the drive mechanism 300, and the output end of the transmission mechanism 400 is connected to the plug-in unit 500, so as to transmit the power of the drive mechanism 300 to the plug-in unit 500. Specifically, the transmission mechanism 400 includes a rocker 410 and a guide rail 440, the input end of the rocker 410 is fixedly connected to the fixed column 310, and the output end is slidably connected to the plug-in unit 500; the guide rail 440 is fixedly installed in the housing 100, and the plug-in unit 500 is slidably arranged in the guide rail 440.

[0096] When the rotating part 330 of the operating driving mechanism 300 rotates along the central axis, the rotating part 330 drives the rocker 410 to rotate together, and the rocker 410 drives the plug-in unit 500 to move linearly along the guide rail 440 in cooperation with the transmission slot 450 and the transmission column 460 .

[0097] Preferably, there are two rockers 410, which are respectively arranged on both sides of the plug-in unit 500. The transmission mechanism 400 also includes a connecting rod 470, and both ends of the connecting rod 470 are respectively fixedly connected to the two rockers 410, and the two rockers 410 form a whole, so that the plug-in unit 500 is more stable and smooth during movement.

[0098] like Figure 8 As shown, the bus duct plug-in box 10 further includes an anti-misoperation mechanism 800 for preventing the rotating portion 330 from rotating relative to the housing 100. Fig. 9 and Fig.10 As shown, the anti-misoperation mechanism 800 includes a limit pin 830 and a limit slot 850. The limit pin 830 is fixedly arranged on the rotating part 330. The limit slot 850 is opened on the housing 100 or the fixed part 320. The limit pin 830 is movably arranged in the limit slot 850. Fig. 9 As shown, when the limiting pin 830 is inserted into the limiting groove 850, the rotation part 330 and the fixed part 320 can be locked, and the rotation part 330 cannot rotate relative to the fixed part 320. Fig.10As shown, when the limiting pin 830 leaves the limiting groove 850 , the locking between the rotating part 330 and the fixed part 320 is released, and the rotating part 330 can rotate relative to the fixed part 320 .

[0099] The plug-in unit 500 can be moved to the connection position or the separation position by rotating the rotating part 330 of the driving mechanism 300, so as to realize the function of the main circuit unit 710 taking power from the bus duct 20 (the plug-in unit 500 is in the connection position) or disconnecting power (the plug-in unit 500 is in the separation position). In the above embodiment, the rotating driving mechanism 300 sets the plug-in unit 500 to the connection or separation position by rotating. In other embodiments of the present application, other movement modes may be used, such as sliding, rolling, swinging, etc.

[0100] like Fig. 9 and Fig.10 As shown, the anti-misoperation mechanism 800 further includes an anti-misoperation body 810 and a rotating shaft 820, and the anti-misoperation body 810 is rotatably mounted on the rotating portion 330 via the rotating shaft 820. The limiting pin 830 is disposed on the anti-misoperation body 810, and the limiting groove 850 is provided on the housing 100 or the fixing portion 320. Fig. 9 As shown, when the anti-misoperation body 810 is lifted, the limit pin 830 can be driven to insert into the limit groove 850; Fig.10 As shown, when the anti-misoperation body 810 is pressed, the limiting pin 830 can be driven to leave the limiting groove 850 .

[0101] Please continue to see Fig. 9 and Fig.10 The anti-misoperation mechanism 800 further includes a second resetting elastic member 840. The second resetting elastic member 840 is installed between the anti-misoperation body 810 and the rotating part 330 in a compressed state. Fig. 9 As shown, at this time, the anti-misoperation body 810 is in a default locked state, and the second reset elastic member 840 in the figure keeps the anti-misoperation body 810 in this position. At this time, the limit pin 830 in the figure is inserted into the limit groove 850 on the housing 100 or the fixed part 320, and the rotating part 330 cannot rotate. Fig.10 As shown, at this time, the anti-misoperation body 810 is in an unlocked state, and the second reset elastic member 840 in the figure is compressed. The anti-misoperation body 810 rotates along the rotating shaft 820 and drives the limit pin 830 to rise. The limit pin 830 is separated from the housing 100 or the fixed part 320, and the rotating part 330 can rotate at this time.

[0102] Although the anti-misoperation body 810 in this embodiment is press-type and can automatically reset, in other embodiments the anti-misoperation body 810 can also be rotating, sliding or swinging. Of course, no matter which method is used, the anti-misoperation body 810 needs to have an automatic reset function, otherwise the anti-misoperation function will be lost.

[0103] The bus duct plug-in box 10 is additionally provided with the anti-misoperation mechanism 800 so that the rotating part 330 thereof has the function of preventing misoperation and preventing poor contact of the plug-in unit 500 .

[0104] The plug-in unit 500 can be moved to the connection position or the separation position by rotating the rotating part 330. To rotate the rotating part 330, the default pop-up anti-misoperation body 810 must be pressed and kept pressed before the rotating part 330 can be rotated. This can prevent power failure and electric shock accidents caused by misoperation or accidental contact, making the product safer and more reliable.

[0105] When the plug-in unit 500 moves from one position to another, the rotating part 330 needs to be rotated into place. After the rotating part 330 is in place, the rotating part 330 will not be able to continue to rotate in the rotating direction. After stopping pressing the anti-misoperation main body 810, if the anti-misoperation main body 810 automatically pops up, it means that the plug-in unit 500 is in the correct connection position or separation position at this time, and the plug-in unit 500 will not be connected or separated in a virtual manner; if the rotating part 330 can still continue to rotate in the rotating direction, or the anti-misoperation main body 810 cannot automatically pop up after stopping pressing, it means that the plug-in unit 500 is not in the correct connection position or separation position, which may cause the plug-in unit 500 to be connected or separated in a virtual manner.

[0106] like Figure 6 , Fig.14 and Fig.15 As shown, when installing the bus duct plug-in box 10, the grounding protection rail 600 must be first clamped on the bus duct 20, and then the operating component 210 is pulled (the plug-in unit 500 must be in the separated position at this time, otherwise the operating component 210 cannot be pulled out and the bus duct plug-in box 10 cannot be installed) to make the bus duct plug-in box 10 fit the bus duct 20, and then release the operating component 210, the operating component 210 will automatically reset and clamp on the bus duct 20. When the bus duct plug-in box 10 is removed from the bus duct 20, the plug-in unit 500 must be placed in the separated position (otherwise the operating component 210 cannot be operated), and the operating component 210 must be pulled out to separate the bus duct plug-in box 10 from the bus duct 20, and the removal of the bus duct plug-in box 10 from the bus duct 20 is completed.

[0107] The grounding protection rail 600 is connected to the housing 100 at the same potential, and when the grounding protection rail 600 is mounted on the bus duct 20, the grounding protection rail 600 is connected to the bus duct 20 at the same potential. When the bus duct plug-in box 10 is installed, the grounding protection rail 600 first contacts the bus duct 20, and when the bus duct plug-in box 10 is removed, the grounding protection rail 600 is separated from the bus duct 20 last, thereby realizing the protection system being connected first and then separated, ensuring the personal safety of the operator, and making the product have higher safety and reliability.

[0108] The above installation and removal operations of the bus duct plug-in box 10 can be carried out without powering off the bus duct system. At the same time, it can avoid accidental contact between the plug-in unit 500 and the bus duct 20 during the installation or removal of the bus duct plug-in box 10, and prevent problems such as arcing or short circuit caused by poor contact, which threaten the safety of operators and the function of the bus duct system, so that the product has higher safety and reliability.

[0109] like Fig.16 As shown, the bus duct plug-in box 10 also includes an independent main circuit unit compartment 120 and a main circuit unit 710. The main circuit unit compartment 120 is arranged in the housing 100, and the internal space of the housing 100 is isolated from the main circuit unit compartment 120 by the compartment partition 140, the interlocking mechanism fixed part 110, the side plate 150, and the top plate 160. The main circuit unit 710 is fixedly installed in the main circuit unit compartment 120. The main circuit unit 710 can include only a single-way switch or a multi-way switch, and the number of circuit switches can be flexibly configured according to actual needs.

[0110] like Fig.16 As shown, the bus duct plug-in box 10 also includes an independent monitoring unit compartment 130 and a monitoring unit 720. The monitoring unit compartment 130 is arranged in the housing 100, and the internal space of the housing 100 is isolated from the monitoring unit compartment 130 by the compartment partition 140, the interlocking mechanism fixed part 110, the side plate 150, and the top plate 160. The monitoring unit 720 is fixedly installed in the monitoring unit compartment 130. When inspecting the monitoring unit 720, it is only necessary to open the side plate 150 on one side of the monitoring unit 720, thereby realizing maintenance and inspection of the monitoring unit 720 without powering off the main circuit unit 710, which is convenient for the inspection and maintenance of the product during the use cycle.

[0111] The bus duct plug-in box 10 supports the maintenance of the monitoring unit 720 when the main circuit unit 710 is not powered off, and naturally supports the maintenance of the monitoring unit 720 when the main circuit unit 710 is powered off. The main circuit unit 710 and the monitoring unit 720 in the above-mentioned embodiment of the utility model are isolated and arranged by the compartment partition 140. In other embodiments of the present application, the main circuit unit 710 and the monitoring unit 720 may not be isolated and arranged. When they are not isolated, the main circuit unit 710 needs to be powered off to inspect and maintain the monitoring unit 720.

[0112] like Fig.17 and Fig.18 As shown, the bus duct system of the present application includes the above-mentioned bus duct plug-in box 10 and bus duct 20. The bus duct plug-in box 10 is detachably mounted on the bus duct 20 and is electrically connected to the bus duct 20. Specifically, in one embodiment of the present application, it can be as follows Fig.17 As shown, the bus duct plug-in box 10 is horizontally installed on the bus duct 20. In another embodiment of the present application, as shown in FIG. Fig.18 As shown, the bus duct plug-in box 10 is vertically installed on the bus duct 20. The bus duct plug-in box 10 supports both horizontal installation and vertical installation, and has high flexibility.

[0113] like Fig.14 , Fig.15 As shown, the bus duct plug-in box 10 is detachably mounted on the bus duct 20 through the grounding protection rail 600 and the operating component 210. Specifically, the bus duct 20 is provided with a transfer groove 201 and a flat groove 202, and the bus duct plug-in box 10 is detachably clamped in the transfer groove 201 and the flat groove 202. Specifically, the grounding protection rail 600 of the bus duct plug-in box 10 is provided with a fixed buckle 610, the fixed buckle 610 is adapted to the transfer groove 201, and the fixed buckle 610 can be clamped into the transfer groove 201; the operating component 210 is provided with a movable buckle 211, the movable buckle 211 is adapted to the flat groove 202, and the movable buckle 211 can be clamped into the flat groove 202.

[0114] When the bus duct plug-in box 10 is installed on the bus duct 20, the bus duct plug-in box 10 is rotated counterclockwise with the clamping point of the fixed buckle 610 and the transfer slot 201 as the center of the circle to make it fit with the bus duct 20, and the operating part 210 is released. The moving buckle 211 of the operating part 210 will automatically reset and be clamped on the flat groove 202.

[0115] When the bus duct plug-in box 10 is removed from the bus duct 20, pull out the operating component 210 to disengage the movable buckle 211 from the flat groove 202, and then rotate the bus duct plug-in box 10 clockwise with the clamping point of the fixed buckle 610 and the transfer groove 201 as the center of the circle until the grounding protection guide rail 600 is disengaged from the bus duct 20. At this time, the bus duct plug-in box 10 is completely removed from the bus duct 20.

[0116] In the above embodiment of the present application, the grounding protection rail 600 is of a snap-on type, and in other embodiments of the present application, it may also be of a plug-in type or a mechanism-locked type. In the above embodiment of the present application, the grounding protection rail 600 of the bus duct plug-in box 10 rotates along the snap-on point during installation, and in other embodiments of the present application, it may also be of a sliding type.

[0117] The bus duct plug-in box 10 supports installation or removal without powering off the bus duct system, rapid deployment, and flexible adjustment. Of course, it also supports installation or removal of the bus duct plug-in box 10 when the bus duct system is powered off.

[0118] The bus duct plug-in box 10 has a reasonable interlocking mechanism 200, which supports the safe and reliable installation or removal of the bus duct plug-in box 10 without power failure of the bus duct system, thereby achieving rapid deployment. The bus duct plug-in box 10 also supports the maintenance and repair of the monitoring unit 720 without power failure of the bus duct system and the main circuit unit 710. At the same time, whether installing, removing or maintaining the bus duct plug-in box 10, the communication of the bus duct system can be kept online, eliminating the impact of power failure and communication failure during maintenance.

[0119] The bus duct plug-in box 10 of the utility model has the following beneficial effects:

[0120] 1. High safety and high reliability: safe and reliable interlocking mechanism 200. The bus duct plug-in box 10 can be connected and fixed with the bus duct 20 only when the plug-in unit 500 is in the separated position. When the plug-in unit 500 is in the connected position, the bus duct plug-in box 10 cannot be connected and fixed with the bus duct 20.

[0121] 2. High reliability: The anti-misoperation mechanism 800 prevents misoperation. The driving mechanism 300 has an anti-misoperation function. If you want to rotate the driving mechanism 300, you must first press and keep the default pop-up anti-misoperation body 810 on the driving mechanism 300 pressed down before you can rotate the driving mechanism 300, effectively preventing power outages and electric shock accidents caused by misoperation.

[0122] 3. High safety: The grounding component (grounding protection rail 600) is connected first and then separated, which is a safe connection method. When the bus duct plug-in box 10 is connected to the bus duct 20, the grounding protection rail 600 is connected to the bus duct 20 first, and the other components are connected later than the grounding protection rail 600; when the bus duct plug-in box 10 is separated from the bus duct 20, the grounding protection rail 600 is separated last, and the other components are separated earlier than the grounding protection rail 600. The bus duct plug-in box 10 provides continuous and reliable grounding protection, further improving the safety of operation.

[0123] 4. High safety and convenience: The main circuit unit 710 is isolated from the monitoring unit 720, which is safer during maintenance. Compared with the main circuit unit 710, the monitoring unit 720 is maintained much more frequently. By isolating the main circuit unit 710 from the monitoring unit 720, the monitoring unit 720 can be repaired and maintained without powering off the main circuit unit 710, ensuring the safety of the maintenance personnel while ensuring the normal operation of the main circuit unit 710.

[0124] 5. High reliability: The communication transmission unit 740 does not drop off the line. The bus duct plug-in box 10 is separated from the bus duct 20. When the bus duct plug-in box 10 is out of work, the communication transmission unit 740 can be separated from the bus duct plug-in box 10 separately to keep the communication transmission unit 740 from dropping off the line.

[0125] 6. Flexibility: The bus duct junction box 10 supports both horizontal and vertical installation.

[0126] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
