Description

Technical Field

[0001] The present application belongs to the field of semiconductor equipment, such as functions applied to semiconductor equipment or data transmission equipment, and in particular, relates to a distribution box and a server system equipped with the distribution box. Background Art

[0002] Semiconductor equipment usually works 24 hours a day. As a node in the network, the server needs to work with high stability, high performance and high safety. Therefore, the distribution box used to power the server is particularly important.

[0003] In the prior art, the existing distribution boxes are mostly equipped with circuit breakers. When the current in the circuit exceeds the rated value of the equipment, the molded case circuit breaker will automatically cut off the circuit to prevent the equipment from being damaged due to overload. Similarly, when a short circuit occurs in the circuit, the molded case circuit breaker can also quickly cut off the circuit to prevent the short circuit from causing greater damage to the equipment and lines; at the same time, the circuit breaker also plays a protective role such as undervoltage, phase loss, and phase failure. However, in the prior art, when the molded case circuit breaker cuts off the circuit due to overload or short circuit, all the corresponding low-voltage modules lose power supply. Although this comprehensive power-off method can ensure the safety of equipment and lines, it may bring some inconvenience or potential safety risks in some cases. After the comprehensive power-off, the staff needs to check the source of the fault in turn and check each low-voltage module one by one, which increases the difficulty and time cost of troubleshooting and causes the server to be down for too long.

[0004] Based on the above, this application is filed. Utility Model Content

[0010] In a further solution of the present application, the first switching power supply and the second switching power supply are both V power supply or V power supply.

[0011] In a further scheme of the present application, the three-phase main line is located at the front end of the main circuit breaker and is also connected in sequence to a surge protector and a three-phase filter, and the surge protector and the three-phase filter are located at the rear end of the heavy-load connector; wherein the surge protector is connected in parallel between the heavy-load connector and the three-phase filter.

[0036] In this application, if there is a feature defined as "first" or "second", it is only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Features defined as "first" or "second" may explicitly or implicitly include at least one of the defined features.

[0037] In the description of this specification, if the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they are contradictory.

[0038] like Figure 1 and Figure 2 The embodiment of the utility model first provides a distribution box 1000, which is applied to the power supply of a server. The server refers to a computer hardware device of a semiconductor device. The distribution box 1000 is a chassis module with a modular design, including a shell 200 and a distribution module 100 arranged in the shell 200. The overall design is a compact module, so that the distribution box 1000 can be easily integrated into the server cabinet, effectively saving space and improving space utilization. The distribution box 1000 can directly and individually control the power supply of the corresponding server, which provides great convenience for the independent management and maintenance of the server. And when maintaining or replacing, the distribution box 1000 can be directly replaced without disassembling or large-scale modification of the entire distribution box, thereby reducing the downtime of the server. Among them, the distribution module 100 is the hardware of the distribution box 1000, and some components in the distribution module 100 are placed outside the shell 200 for easy operation.

[0039] like Figure 3 The power distribution module 100 includes a main power supply module 10, a power supply module 20 and a low voltage module 30; wherein the main power supply module 10 is used to obtain electric energy from an external power supply and perform necessary conversions on it to ensure that the required electric energy is obtained in the system. Taking the power supply system used in semiconductor factories as an example, the external power supply provides three-phase 208V electric energy, while the server usually requires a single-phase 220V power supply. At this time, the main power supply module 10 converts the three-phase 208V electric energy into the single-phase 220V power supply required by the server.

[0040] Furthermore, the main power supply module 10 includes a three-phase main line 11, i.e., the main line for power transmission, which is responsible for introducing power from an external power source into the module. Furthermore, a main circuit breaker 12 is connected in series to the three-phase main line 11. When an abnormal situation such as overload or short circuit occurs in the circuit, the main circuit breaker 12 can quickly cut off the circuit, thereby protecting the safety of the entire three-phase main line 11.

[0041] The power module 20 includes a first switching power supply 21 and a second switching power supply 22 to convert the alternating current of the main power supply module 10 into direct current.

[0042] Optionally, the first switching power supply 21 and the second switching power supply 22 may have different output voltage and current characteristics to meet the power supply requirements of different hardware devices in the system. For example, some hardware devices may require higher voltage and current, while other devices may only require lower voltage and current. By properly configuring the two switching power supplies, the power supply module 20 can provide power supply support for a variety of different devices.

[0043] The low voltage module 30 includes a protection unit 31 and a control unit 32;

[0044] The protection unit 31 refers to a low-voltage module that the main power supply module 10 can detect and protect, such as overcurrent protection, overvoltage protection, overtemperature protection, fire protection and other safety measures, which are used to monitor abnormal conditions and make current control for the main power supply module 10. For example, when the current or voltage exceeds the safety range, the protection unit 31 will respond quickly, such as cutting off the power supply or adjusting the current parameters, to prevent equipment damage or safety accidents.

[0045] The control unit 32 is a functional low-voltage module, which is associated with a specific device that needs power supply inside the distribution box 1000. The control unit 32 receives the power from the main power supply module 10 and converts it into the appropriate form required by the device. It ensures that the devices inside the distribution box or the devices connected to the external distribution box can operate normally and obtain the required power supply.

[0046] Based on the general inventive concept of the first embodiment of the utility model, the input end of the first switching power supply 21 is connected to the three-phase main line 11 and is located at the front end of the main circuit breaker 12, and the output end protection unit 31;

[0047] The input end of the second switching power supply 22 is connected to the three-phase main line 11 and is located at the rear end of the main circuit breaker 12, and the output end is connected to the control unit 32; when the main circuit breaker 12 is in the disconnected state, the protection unit 31 remains connected and the control unit 32 is disconnected.

[0048] It should be noted that "front end" and "rear end" are only used to describe the relative position of components or equipment in the entire three-phase main line 11, mainly with the direction of current flow as a reference. For example, the input end of the first switching power supply 21 is connected to the three-phase main line 11 and is located at the front end of the main circuit breaker 12, which means that the first switching power supply 21 receives electrical energy from the three-phase main line 11 before the current passes through the main circuit breaker 12.

[0049] It can be understood that the protection unit 31 is connected to the output end of the first switching power supply 21. Since the input end of the first switching power supply 21 is connected to the three-phase main line 11 and is located at the front end of the main circuit breaker 12, this means that even if the main circuit breaker 12 is in an off-circuit state, the protection unit 31 can still remain connected, thereby ensuring that the key protection function is not affected. The control unit 32 is connected to the output end of the second switching power supply 22. Since the input end of the second switching power supply 22 is connected to the three-phase main line 11 and is located at the rear end of the main circuit breaker 12, when the main circuit breaker 12 is in an off-circuit state, the control unit 32 will be disconnected, that is, the power supply will be lost. Such a design allows the control unit 32 to be safely disconnected by operating the main circuit breaker 12 when the system needs to be maintained or repaired, while maintaining the connection of the protection unit 31 to ensure the safety of the system.

[0050] Through the design of the main circuit breaker 12, the power supply system realizes convenient control of the power supply to the control unit 32. When the main circuit breaker 12 responds and disconnects, it can safely cut off the power supply to the control unit 32, which effectively prevents equipment damage or personal injury caused by accidental startup or current surge.

[0051] At the same time, even if the control unit 32 loses power supply due to the action of the main circuit breaker 12, the protection unit 31 can still maintain the working state. This protection unit 31 can continue to perform functions including monitoring the inside of the distribution box and protecting the main power supply module to ensure the safety of the distribution box 1000.

[0052] A specific embodiment is provided below:

[0053] like Figure 4 , the current in the three-phase main line 11 is exemplarily transmitted from left to right, and includes a heavy-duty connector 13, a surge protector 14, a three-phase filter 15, a main circuit breaker 12, a fuse 16, and a contact switch 17 in sequence;

[0054] The heavy-duty connector 13 , the surge protector 14 , and the three-phase filter 15 are sequentially arranged at the front end of the main circuit breaker 12 ; the fuse 16 and the contact switch 17 are sequentially arranged at the rear end of the main circuit breaker 12 .

[0055] Specifically, the heavy-duty connector 13 is connected to the three-phase main line 11 and is located at the front end of the main circuit breaker 12, so as to connect the voltage of the three-phase main line 11. The three-phase main line 11 is composed of three main lines U, V and W, and a PE ground line. The heavy-duty connector 13 can withstand high current and high voltage to ensure the stability of power supply. The three-phase filter 15 is connected to the rear end of the heavy-duty connector 13 to filter out the harmonics in the three-phase main line 11. During the power transmission process, harmonic interference may be generated due to the presence of various nonlinear loads. It will not only affect the stability of the power system, but also may cause damage to electrical equipment. The three-phase filter 15 can effectively filter out these harmonics, improve the quality of electric energy, and protect the stability of power transmission.

[0056] The surge protector 14 is connected in parallel between the heavy-duty connector 13 and the three-phase filter 15, and is respectively connected to the three main lines U, V and W and the ground line. The surge protector 14 can effectively protect the entire system from the impact of surge voltage. First, the surge protector 14 can absorb and discharge the surge overvoltage in the three-phase main line 11. When a surge overvoltage appears in the line, the surge protector will respond quickly and discharge the overvoltage energy into the ground or other circuits, thereby protecting other equipment in the system from damage. Secondly, since the surge protector 14 is connected in parallel between the heavy-duty connector 13 and the three-phase filter 15, it can pre-process the power entering the system. After the power enters the system through the heavy-duty connector 13, the surge protector 14 will first absorb and discharge the possible surge overvoltage to ensure that the subsequent three-phase filter 15 can receive stable and pure power.

[0057] Furthermore, after the current flows out from the main circuit breaker 12 , it first passes through the fuse 16 , the contact switch 17 , and then reaches the indicator light 18 .

[0058] It can be understood that the function of the fuse 16 is to quickly melt when the load current after the main circuit breaker 12 exceeds its rated value, thereby cutting off the circuit and protecting the circuit and other equipment from damage. This is an important safety measure to prevent circuit overload or short circuit and other faults; the contact switch 17 is used to control the on and off of the circuit. It can be operated by electromagnetic or other means to achieve the connection or disconnection of the circuit. When the contact switch 17 is in a closed state, the current can continue to flow smoothly through it; and when it is in an open state, the current will be cut off, thereby achieving control of the circuit. The indicator light 18 is used to indicate the power-on state of the three-phase main line 11. The three-phase main line 11 is likely to be the main part of the power supply system, responsible for providing electrical energy to the load. The indicator light 18 is exposed to the outside of the housing 200; its on and off state can intuitively indicate to the user or maintenance personnel whether the three-phase main line 11 is in a power-on state, thereby monitoring the working state of the three-phase main line 11 and providing a reference for troubleshooting.

[0059] like Figure 5 The indicator lights 18 are respectively connected between different lines of the three-phase main line 11. Specifically, there are two indicator lights 18, one of which is connected to the two main lines U and V, and the other is connected to the two main lines V and W. The indicator lights are respectively connected between different lines of the three-phase main line 11, mainly to monitor the power-on status of each phase or between phases in the three-phase power system, and provide users or maintenance personnel with more comprehensive and accurate circuit status information.

[0060] It can be understood that when two indicator lights are connected between the U, V lines and the V, W lines respectively, each indicator light can independently reflect the power status of the lines it is connected to. If a certain indicator light is off, while other indicator lights are on normally, it can be preliminarily determined that there is a problem with the line or phase connected to the indicator light. For example: if the indicator light connected to the U, V lines is off, while the indicator light connected to the V, W lines is on, it may mean that the U line has lost power; if both indicator lights are off, it may be that all three lines have lost power, or there may be a problem with only the V line; if both indicator lights are on, it usually means that the U, V, and W lines in the three-phase system are working normally.

[0061] Continue reading Figure 4 The three-phase main line 11 is also connected to a monitoring display 19, which has multiple interfaces, some of which are connected between the surge protector 14 and the main circuit breaker 12 through an induction coil to display and monitor the power parameters of the main power supply module 10; another part of the interfaces of the monitoring display 19 are respectively connected to the rear end of the main circuit breaker 12.

[0062] It can be understood that the monitoring display 19 can detect and display the original power parameters of the main power supply module 10, including voltage, current, frequency, etc., in real time by connecting to the front end of the main circuit breaker 12. Connected at the rear end of the main circuit breaker 12, the monitoring display 19 can monitor the circuit load status after passing through the main circuit breaker, fuse and other protective devices in real time; it helps to observe whether the circuit is operating normally, whether the load is balanced, and whether there is an overload or abnormal situation. And by comparing the monitoring data relative to the front and rear ends of the main circuit breaker 12, the fault can be more accurately located and isolated. For example, if the data at the front end of the main circuit breaker 12 is normal, but the data at the rear end of the main circuit breaker 12 is abnormal, then the fault may occur in the part after the main circuit breaker 12, such as the fuse 16, the load, etc.

[0063] Furthermore, an input end of the first switching power supply 21 is connected between the three-phase filter 15 and the main circuit breaker 12 , and an input end of the first switching power supply 21 is connected between the fuse 16 and the main circuit breaker 12 .

[0064] First, the three-phase filter 15 is located before the main circuit breaker 12 to filter out noise and interference from the power supply, ensuring a stable and clean power input for the first switching power supply 21. The first switching power supply 21 can therefore obtain electrical energy from the filtered power supply and convert it into the required direct current to provide stable electrical energy for the protection unit 31. Secondly, the fuse 16 is located after the main circuit breaker 12 to protect the circuit from damage caused by current overload. When the current in the circuit exceeds the rated value of the fuse, the fuse will quickly blow and cut off the circuit. The second switching power supply 22 is connected before the fuse 16, that is, the second switching power supply 22 is not protected by the fuse 16. If an abnormal current appears in the circuit, the control unit 32 connected to the second switching power supply 22 can still remain in working condition when the fuse 16 cuts off the circuit.

[0065] like Figure 7 The protection unit 31 includes a smoke detection sensor 311, a temperature detection sensor 312 and a protection controller 313. The smoke detection sensor 311, the temperature detection sensor 312 and the protection controller 313 form a control loop, and the protection controller 313 is connected to the heavy-duty connector 13. Similarly, the smoke detection sensor 311, the temperature detection sensor 312 and the protection controller 313 are also electrically connected and are configured to independently trigger the protection controller 313, and the protection controller 313 further controls the heavy-duty connector 13 to cut off the three-phase main line 11.

[0066] It can be understood that the smoke detection sensor 311 and the temperature detection sensor 312 are configured to independently trigger the protection controller 313, that is, whether the smoke concentration exceeds the preset threshold or the current temperature exceeds the safe range, the smoke detection sensor 311 and the temperature detection sensor 312 detect an abnormal situation and directly trigger the protection controller 313, and then when the protection controller 313 receives a trigger signal from the smoke detection sensor 311 or the temperature detection sensor 312, the protection controller 313 responds through the received signal, specifically, sends an instruction to the heavy-duty connector 13; after the heavy-duty connector 13 receives the instruction from the protection controller 313, it executes a rapid disconnection of the three-phase main line 11, thereby cutting off the power supply of the entire three-phase main line 11. It is intended to prevent fire or other dangerous situations caused by power failures. This design ensures the safety and reliability of the power system. Through real-time monitoring of smoke and temperature, and the rapid response of the heavy-duty connector 13, the system can cut off the power supply in time before potential danger occurs to protect the safety of equipment and personnel. At the same time, the independent triggering mechanism of the sensor improves the flexibility and response speed of the system, so that the system can better cope with various abnormal situations.

[0067] In combination with the above, when the main circuit breaker 12 is disconnected, although the load connected to the three-phase main line 11 is disconnected, the circuit components located at the front end of the main circuit breaker 12 can still keep operating, that is, the smoke detection sensor 311 and the temperature detection sensor 312 can still monitor the inside of the distribution box 1000 to prevent potential risks and avoid damage to the server and equipment loss; and at the same time provide a reference for subsequent troubleshooting and positioning.

[0068] like Figure 8 The control unit 32 includes a cooling fan 321, a main contactor 322 and a key switch 323; the main contactor 322 is connected to the rear end of the second switching power supply 22 and is electrically connected to the contact switch 17 to control the connection or disconnection of the three-phase main line 11 at the rear end of the second switching power supply 22; the cooling fan 321 is arranged at the housing 200 to dissipate heat for the distribution module 100; the key switch 323 is arranged at the housing 200 and is connected to the main circuit breaker 12 and / or the heavy-load connector 13.

[0069] It can be understood that when the contact switch 17 is closed, the main contactor 322 will also be closed, thereby allowing current to pass through the three-phase main line; conversely, when the contact switch 17 is disconnected, the main contactor will also be disconnected, thereby cutting off the current supply. The cooling fan 321 removes the heat inside the module by generating airflow to ensure that the module operates within an appropriate temperature range. The key switch 323 is a safety mechanism for controlling the power on and off of the distribution module. Only when the correct key is inserted and turned to the correct position will the main circuit breaker 12 or the heavy-duty connector 13 be allowed to close, thereby allowing current to pass. This design can prevent unauthorized personnel from arbitrarily operating the distribution module, thereby improving the safety of the system. At the same time, in an emergency, by operating the key switch 323, the power supply can be quickly cut off to ensure the safety of personnel and equipment.

[0070] like Figure 6 The low voltage module 30 further includes an emergency stop unit 33, which is connected to the three-phase main line 11 and is located at the rear end of the main circuit breaker 12; the emergency stop unit 33 is electrically connected to the main circuit breaker 12 to control the connection or disconnection of the main circuit breaker 12. That is, it can provide an additional emergency disconnection function when the main circuit breaker 12 is already closed.

[0071] It can be understood that the emergency stop unit 33 is an emergency stop button, the purpose of which is to provide a quick and direct way to cut off the power supply in the event of an accident. When an emergency or accident occurs, the staff can quickly press the button of the emergency stop unit 33, which will trigger a control signal to immediately disconnect the main circuit breaker 12, thereby cutting off the power supply of the three-phase main line 11 and protecting personnel and equipment from further injury or damage. The emergency stop unit 33 can be set at a certain distance from the distribution box 1000, such as 3 to 10 meters. This setting ensures that in the event of an emergency, the staff can still easily access and operate the emergency stop unit 33 without approaching the distribution box 1000, thereby ensuring the safety of the staff.

[0072] Furthermore, the first switching power supply 21 and the second switching power supply 22 are both 24V power supplies or 12V power supplies, depending on the specific rated parameters of the protection unit 31 and the control unit 32 , so as to provide a stable DC power supply for the protection unit 31 and the control unit 32 .
