Description

Technical Field

[0001] The utility model belongs to the field of power distribution systems, and in particular relates to a power distribution system for a data center. Background Art

[0002] As the core carrier of information infrastructure, data centers are responsible for storing, processing and transmitting massive amounts of data. The stability, reliability and energy efficiency of their power distribution systems directly affect the safe operation and operating costs of data centers.

[0003] At present, in traditional power distribution systems, the conductive connection between the distributor and the power supply usually adopts fixed wiring or ordinary plug-in structure, which has problems such as insufficient connection stability. When faced with abnormal currents such as overload and short circuit, the distributor relies on internal circuit breakers or external protection devices to cut off the current. The response speed is slow and local overheating may occur due to poor contact, threatening system safety. Utility Model Content

[0004] In order to overcome the problems of insufficient stability of conductive connection between existing distributors and power supplies, slow response to abnormal current cutoff, and poor contact, a power distribution system for a data center is proposed.

[0005] The technical solution of the utility model is: a power distribution system for a data center, including a power distribution cabinet, one end of which is equipped with a power connector, and a power distributor, an overload relay, and a controller are fixedly connected to the power distribution cabinet; two U-shaped mounting blocks are fixedly mounted on the upper end of the power distribution cabinet by screws, and the ends of the two U-shaped mounting blocks close to each other are fixedly connected to a protective tube, and a conductive mechanism is provided in the protective tube;

[0006] A U-shaped bottom plate is fixedly connected to the bottom surface of the inner wall of the power distribution cabinet, and two first U-shaped sliders and two second U-shaped sliders are slidably provided on the U-shaped bottom plate.

[0007] The conductive mechanism includes a flashlight, a second conductive area, and a second servo motor; a fixed cylinder is fixedly connected to the U-shaped mounting block, the second servo motor is fixedly connected to the inner wall of the fixed cylinder, a power post is fixedly connected to the output shaft of the second servo motor, and the side wall of the power post is provided with a second conductive area; a flashlight is provided at one end of the first circuit breaker away from the second circuit breaker, the flashlight is electrically connected to the circuit output end of the first circuit breaker, the inner wall of the flashlight is provided with the first conductive area, and the inner wall of the flashlight is in contact with the side wall of the power post;

[0008] When the connecting post rotates and the first conductive area and the second conductive area come into contact, the first circuit breaker and the connecting post are electrically connected. One end of a third wire is installed on the connecting post, and the other end of the third wire is electrically connected to the connecting terminal of the distributor.

[0009] The second circuit breaker is provided with a separation mechanism for adjusting the position of the first circuit breaker.

[0010] When in use, the first U-shaped slider and the second U-shaped slider are both placed on the U-shaped bottom plate, and the first U-shaped slider and the second U-shaped slider can both slide along the side walls of the U-shaped bottom plate. When it is necessary to cut off the current output by the first circuit breaker, it is only necessary to turn on the second servo motor to rotate the connecting post so that the second conductive area on the connecting post and the first conductive area on the inner wall of the connecting flashlight are not in contact, thereby achieving rapid disconnection of the circuit. In addition, the separation mechanism can also be turned on to move the first circuit breaker toward the second circuit breaker, so that the connecting post and the connecting flashlight are separated, thereby achieving rapid disconnection of another circuit.

[0011] Furthermore, bolts are threadedly installed on the two second U-shaped sliders, and the bolts pass through the second U-shaped sliders and are threadedly installed on the U-shaped bottom plate.

[0012] Furthermore, the separation mechanism includes a fixed seat, a first servo motor, a screw and a threaded sleeve; the side wall of the second circuit breaker is fixedly connected to the fixed seat, the side wall of the first circuit breaker is fixedly connected to the threaded sleeve, the first servo motor is fixedly connected to the fixed seat, the output shaft of the first servo motor passes through the fixed seat and is fixedly connected to the screw, and the side wall of the screw is threadedly installed on the inner wall of the threaded sleeve.

[0013] Furthermore, a power connection body is provided at one end of the second circuit breaker close to the power connection head, and the power connection body is electrically connected to the power input end of the second circuit breaker. A screw hole is penetrated at one end of the distribution cabinet, and the power connection head is threadedly installed on the inner wall of the screw hole. A wire connector is fixedly connected to one end of the power connection head, and a second wire is fixedly connected to the inner wall of the other end of the power connection head. The two second wires are respectively electrically connected to the power connection bodies on the two second circuit breakers.

[0014] Furthermore, the ends of the two protective tubes that are close to each other are respectively fitted with the ends of the two first circuit breakers that are away from each other.

[0015] Furthermore, the protective tube is made of elastic insulating material, the inner wall of the connecting torch is made of insulating material except the first conductive area, and the side wall of the connecting post is made of insulating material except the second conductive area.

[0016] Furthermore, rubber plates are fixed to both sides of the second circuit breaker, and a gap exists between the second circuit breaker and the first circuit breaker.

[0017] Furthermore, the overload relay is electrically connected to the controller, the overload relay is electrically connected to the second servo motor, and the overload relay is electrically connected to the first servo motor.

[0018] Beneficial effects of the utility model:

[0019] 1. By setting up a conductive mechanism, the contact post is driven by a second servo motor to rotate. When the first conductive area is in contact with the second conductive area, the contact flashlight and the contact post are electrically connected through the conductive area. The inner wall of the contact flashlight fits tightly with the side wall of the contact post. Combined with the protective tube wrapping and protecting the contact parts, it can reduce external vibration, dust and other interference, and improve the stability of the conductive connection.

[0020] 2. By setting a second U-shaped slider, which is fixed to the U-shaped bottom plate by bolts, the position of the second circuit breaker can be adjusted as needed and then tightened to avoid loose connection caused by sliding of the slider, further ensuring the stability of the circuit connection;

[0021] 3. By setting up an overload relay, which is electrically connected to the controller, when an abnormal current such as overload or short circuit is detected, the controller can immediately trigger the second servo motor to drive the contact post to rotate, quickly separating the first conductive area from the second conductive area, and cutting off the connection between the first circuit breaker and the distributor. At the same time, the overload relay can synchronously control the first servo motor of the separation mechanism through the controller, driving the threaded sleeve to move via the lead screw, causing the first circuit breaker to slide toward the second circuit breaker, achieving physical separation of the contact flashlight and the contact post, forming a dual rapid disconnection mechanism of conductive area detachment and mechanical separation. The response speed is far superior to the traditional disconnection method that relies on mechanical tripping of the circuit breaker or external protection device;

[0022] 4. By setting a gap between the first circuit breaker and the second circuit breaker and arranging rubber plates on both sides of the second circuit breaker, vibration can be buffered and the relative position of the two can be kept stable, reducing the displacement of the contact part or the loose contact caused by vibration. The sliding matching structure of the U-shaped bottom plate and the first and second U-shaped sliders allows the circuit breaker to slide smoothly when adjusting the position, avoiding poor contact caused by installation errors in traditional fixed wiring. The limiting function of the sliding track can ensure that the power connection post of the conductive mechanism and the power connection flashlight are accurately aligned and fit.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The first circuit breaker 12 and the second circuit breaker 13 are electrically connected via a first wire 23. The second circuit breaker 13 is electrically connected to the power terminal 2.

[0035] The conductive mechanism includes a power connection flashlight 14, a second conductive area 17, and a second servo motor 28.

A first conductive area 15 is provided on the inner wall of the power connection flashlight 14, and the inner wall of the power connection flashlight 14 is in contact with the side wall of the power connection post 16.

[0036] When the connecting post 16 rotates and the first conductive area 15 and the second conductive area 17 come into contact, the first circuit breaker 12 is electrically connected to the connecting post 16.

[0037] The second circuit breaker 13 is provided with a separation mechanism for adjusting the position of the first circuit breaker 12 .

[0038] When in use, the first U-shaped slider 9 and the second U-shaped slider 10 are placed on the U-shaped bottom plate 8, and the first U-shaped slider 9 and the second U-shaped slider 10 can slide along the side walls of the U-shaped bottom plate 8. When it is necessary to cut off the current output by the first circuit breaker 12, it is only necessary to turn on the second servo motor 28 to rotate the power post 16 so that the second conductive area 17 on the power post 16 and the first conductive area 15 on the inner wall of the power torch 14 are not in contact, thereby achieving rapid disconnection of the circuit. In addition, the separation mechanism can also be turned on to move the first circuit breaker 12 toward the second circuit breaker 13, so that the power post 16 and the power torch 14 are separated, thereby achieving rapid disconnection of another circuit.

[0039] See also Figure 1 and Figure 2 In this embodiment, bolts 11 are threadedly installed on the two second U-shaped sliders 10. The bolts 11 pass through the second U-shaped sliders 10 and are threadedly installed on the U-shaped bottom plate 8. The second U-shaped sliders 10 can be fixed to the U-shaped bottom plate 8 by the bolts 11, so that the position of the second circuit breaker 13 can be adjusted according to needs and then fastened to the U-shaped bottom plate 8.

[0040] See also Figure 1 、 Figure 4 and Figure 6In this embodiment, a power connection body 22 is provided at one end of the second circuit breaker 13 near the power connection head 2. The power connection body 22 is electrically connected to the power input end of the second circuit breaker 13. A screw hole 25 is penetrated at one end of the power distribution cabinet 1. The power connection head 2 is threadedly mounted on the inner wall of the screw hole 25. A wire connector 24 is fixedly connected to one end of the power connection head 2.

The second wire 26 connects the power connection body 22 and the power connection head 2, so that the external power supply is stably connected to the second circuit breaker 13 through the wire connector 24, the power connection head 2, and the second wire 26, thereby ensuring the reliability of current input.

[0041] See also Figure 1 and Figure 7 In this embodiment, the ends of the two protective tubes 7 that are close to each other are respectively fitted with the ends of the two first circuit breakers 12 that are away from each other. The protective tubes 7 are fitted with the first circuit breakers 12 and can wrap the contact area between the connection tube 14 and the connection post 16. The elastic insulating material properties are utilized to reduce the interference of external vibration and dust on the conductive mechanism, greatly improving the stability of the conductive connection and providing insulation protection.

[0042] See also Figure 1 、 Figure 2 and Figure 7 In this embodiment, the protective tube 7 is made of elastic insulating material. The inner wall of the flashlight 14 is made of insulating material except for the first conductive area 15, and the side wall of the connecting post 16 is made of insulating material except for the second conductive area 17. The elastic insulating protective tube 7 can buffer vibration and isolate external interference. Only the conductive areas of the flashlight 14 and the connecting post 16 are conductive, and the remaining areas are insulated, avoiding contact between non-conductive areas to cause short circuits or excessive contact resistance, ensuring precise contact between the conductive areas, and solving the problem of poor contact.

[0043] See also Figure 1 and Figure 2 In this embodiment, rubber plates are fixed to both sides of the second circuit breaker 13. A gap exists between the second circuit breaker 13 and the first circuit breaker 12. The rubber plates can buffer vibrations, reduce the rigid collision between the second circuit breaker 13 and the inner wall of the power distribution cabinet 1 or the first circuit breaker 12, and maintain a stable relative position between the two. The gap design avoids direct contact and friction between the first circuit breaker 12 and the second circuit breaker 13, prevents the contact parts from shifting or loosening due to vibration, and improves the stability of the overall structure.

[0044] See also Figure 1 、 Figure 3 and Figure 7In this embodiment, the overload relay 4 is electrically connected to the controller 5, the overload relay 4 is electrically connected to the second servo motor 28, and the overload relay 4 is electrically connected to the first servo motor 19. The overload relay 4 detects the current in real time. When an abnormal current is detected, the output shaft of the second servo motor 28 is synchronously triggered to rotate through the electrical connection, thereby controlling the rotation of the power connection column 16, and the first servo motor 19 can control the separation mechanism to achieve dual rapid disconnection of "conductive area separation + mechanical separation". Compared with traditional protection devices, the response is faster and the disconnection is more reliable.

[0045] Example 2: Please refer to Figure 1 and Figure 3 Based on Example 1, the present application provides a technical solution: the separation mechanism includes a fixed base 18, a first servo motor 19, a screw 20 and a threaded sleeve 21; the side wall of the second circuit breaker 13 is fixedly connected to the fixed base 18, and the side wall of the first circuit breaker 12 is fixedly connected to the threaded sleeve 21. The first servo motor 19 is fixedly connected to the fixed base 18, and the output shaft of the first servo motor 19 passes through the fixed base 18 and is fixedly connected to the screw 20. The side wall of the screw 20 is threadedly installed on the inner wall of the threaded sleeve 21. The first servo motor 19 drives the screw 20 to rotate, and drives the first circuit breaker 12 to move toward or away from the second circuit breaker 13 through the threaded sleeve 21, thereby realizing rapid separation or adhesion of the connection flashlight 14 and the connection post 16, forming a mechanically assisted cutting mechanism, and cooperating with the rotation and cutting of the conductive mechanism to improve the abnormal current cutting response speed.

[0046] Working Principle: When using the power distribution system of this data center, the external power supply is connected to the power connector 2 via the wire connector 24. The power connector 2 is threadedly installed on the inner wall of the screw hole 25 at one end of the power distribution cabinet 1 to facilitate disassembly and maintenance. The second wire 26 on the inner wall of the other end of the power connector 2 is electrically connected to the power connector 22 on the second circuit breaker 13, introducing current into the second circuit breaker 13 and transmitting it to the first circuit breaker 12 via the first wire 23;

[0047] A connection pin 14 is provided at one end of the first circuit breaker 12 away from the second circuit breaker 13. A first conductive area 15 on its inner wall abuts against a second conductive area 17 on the side wall of a connection pin 16 connected to the output shaft of a second servo motor 28 within a fixed cylinder 27 on the U-shaped mounting block 6. The connection pin 16 is electrically connected to the distributor 3 via a third wire 29, forming a complete conductive circuit.

[0048] During normal operation, the first U-shaped slider 9 and the second U-shaped slider 10 can slide on the U-shaped bottom plate 8 to adjust their positions. The second U-shaped slider 10 is fixed to the U-shaped bottom plate 8 by bolts 11 to ensure the stability of the second circuit breaker 13.

[0049] The two protective tubes 7 are made of elastic insulating material. Their ends close to each other are in contact with the ends of the two first circuit breakers 12 that are far away from each other, covering the contact area between the connection torch 14 and the connection post 16 to reduce external vibration and dust interference. The inner wall of the connection torch 14 except the first conductive area 15 and the side wall of the connection post 16 except the second conductive area 17 are all made of insulating material to ensure accurate conduction.

[0050] When the overload relay 4 detects an abnormal current, it is electrically connected to the controller 5 and synchronously triggers the second servo motor 28 and the first servo motor 19. The second servo motor 28 drives the contact post 16 to rotate, separating the second conductive area 17 from the first conductive area 15, quickly cutting off the electrical connection.

[0051] At the same time, the first servo motor 19 is mounted on the fixing seat 18 on the side wall of the second circuit breaker 13. The screw 20 connected to its output shaft is threadedly mounted on the inner wall of the threaded sleeve 21 on the side wall of the first circuit breaker 12. The rotation of the screw 20 drives the threaded sleeve 21 to move, causing the first circuit breaker 12 to slide toward the second circuit breaker 13, thereby mechanically separating the contact flashlight 14 from the contact post 16, forming a dual disconnection mechanism of "conductive zone separation + mechanical separation";

[0052] In addition, the rubber plates on both sides of the second circuit breaker 13 buffer vibrations, and the gap between the second circuit breaker 13 and the first circuit breaker 12 avoids direct contact and friction, maintaining a stable relative position and ensuring the structural reliability of the system during abnormal disconnection, thereby effectively solving the problems of insufficient conductive connection stability, slow abnormal current disconnection response, and poor contact in traditional power distribution systems.
