Description

Technical Field

[0001] This application relates to the field of power technology, and in particular to integrated distribution cabinets and row-level data centers. Background Technology

[0002] With the rapid development of technologies such as cloud computing, big data, and artificial intelligence, the related supporting infrastructure is also constantly developing and iterating. Among them, the power distribution system of data centers is also developing in tandem, and data centers are placing higher demands on the reliability and security of the power supply and distribution system.

[0003] Currently, the modularity and high integration of power distribution cabinets in data centers are mainly reflected in the complete power distribution function from the mains power through uninterruptible power supplies and busbars to information technology (IT) equipment or cooling units. However, the system integration is still not high, and external related components are usually required to realize comprehensive power distribution functions. Moreover, existing power distribution cabinets mainly consider product structure and wiring safety, and basic electrical safety designs such as short circuits, overloads, grounding, and insulation. They lack safety and protection functions in terms of emergency, abnormal, misoperation, and electrical equipment protection, which poses safety hazards and risks. Utility Model Content

[0004] This application provides an integrated power distribution cabinet and a row-level data center to achieve comprehensive power distribution functions without the need for external related components, thereby improving the integration of the power distribution cabinet and providing more comprehensive safety protection functions.

[0005] In a first aspect, embodiments of this application provide an integrated power distribution cabinet, which includes: a cabinet, monitoring equipment, a power distribution management module, an emergency cooling module, and multiple rack-mounted uninterruptible power supplies (UPS).

[0006] The monitoring equipment, the power distribution management module, the emergency cooling module, and the multiple rack-mounted uninterruptible power supplies are all installed inside the cabinet;

[0007] The power distribution management module is connected to the mains power input to provide power input for the multiple rack-mounted uninterruptible power supplies and the cooling equipment in the row-level data center. The output ports of the multiple rack-mounted uninterruptible power supplies are connected to the output busbar, which supplies power to the AC and DC electrical equipment in the integrated power distribution cabinet.

[0008] The aforementioned integrated power distribution cabinet houses monitoring equipment, a power distribution management module, an emergency cooling module, and multiple rack-mounted uninterruptible power supplies (UPS). The power distribution management module connects to the mains power input, providing power to the multiple rack-mounted UPSs and the cooling equipment in the data center. The output ports of the multiple rack-mounted UPSs connect to an output busbar, which can supply power to both AC and DC power devices within the integrated power distribution cabinet. This achieves comprehensive power distribution functionality without the need for external components, thereby improving the integration of the power distribution cabinet.

[0009] In one possible implementation, the integrated power distribution cabinet further includes: an emergency stop switch, an emergency stop relay, and a first shunt trip unit whose first terminal is connected to the main input circuit breaker in the power distribution management module;

[0010] The emergency stop switch is connected to the control contact of the emergency stop relay and is used to respond to the user's emergency stop operation and control the emergency stop relay contact to operate.

[0011] The emergency stop relay is connected to the second terminal of the first shunt trip unit and the emergency stop dry contacts of the plurality of rack-mounted uninterruptible power supplies, respectively. When its own control contacts are activated, it is used to control the first shunt trip unit to activate, disconnect the main input circuit breaker, and control the emergency stop dry contacts of the plurality of rack-mounted uninterruptible power supplies to be in the open state, thereby disconnecting the output of the plurality of rack-mounted uninterruptible power supplies.

[0012] The aforementioned integrated power distribution cabinet has an emergency power outage safety protection function. It is connected to an external emergency stop switch and integrates a first shunt trip unit and an emergency stop relay control circuit internally to ensure that in abnormal emergency situations, the power supply can be centrally cut off to prevent further damage through the emergency stop switch.

[0013] In one possible implementation, the integrated power distribution cabinet further includes: at least one anti-backflow module, each anti-backflow module being connected to at least one of the rack-mounted uninterruptible power supplies;

[0014] The anti-backflow module includes: an anti-backflow relay and a second shunt trip unit. The control contact of the anti-backflow relay is connected to the output dry contact of the rack-mounted uninterruptible power supply. The first end of the second shunt trip unit is connected to the anti-backflow relay, and the second end is connected to the input circuit breaker of the rack-mounted uninterruptible power supply.

[0015] When the output dry contact of the rack-mounted uninterruptible power supply is closed, the anti-reverse current relay controls the contact to activate, thereby triggering the second shunt trip unit to disconnect the input circuit breaker of the rack-mounted uninterruptible power supply.

[0016] The aforementioned integrated power distribution cabinet has a backflow prevention function. The internal uninterruptible power supply input integrates a second shunt trip unit and a backflow prevention relay control circuit to prevent current from flowing back to the input port of the uninterruptible power supply in the event of abnormal or dangerous power or energy, thus avoiding the risk of accidental electric shock to personnel.

[0017] In one possible implementation, the integrated power distribution cabinet further includes: an uninterruptible power supply maintenance bypass mode switching device that is linked to the maintenance bypass switch of the integrated power distribution cabinet;

[0018] The uninterruptible power supply maintenance bypass mode switching device includes: a mechanical locking structure that is displaced when the maintenance bypass switch is activated, and at least one switching assembly connected to the mechanical locking structure, wherein the contacts of each switching assembly are connected to at least one maintenance mode dry contact of the rack-mounted uninterruptible power supply.

[0019] The mechanical locking structure is used to control the switch assembly to a first state when the maintenance bypass switch is open, in which case the maintenance mode dry contact of the rack-mounted uninterruptible power supply is disconnected; and when the maintenance bypass switch is closed, to control the switch assembly to a second state through displacement linkage, in which case the maintenance mode dry contact of the rack-mounted uninterruptible power supply is connected, and the rack-mounted uninterruptible power supply switches to maintenance bypass mode.

[0020] The aforementioned integrated power distribution cabinet has an automatic protection function for maintenance bypass mode. The internal maintenance bypass switch can integrate an uninterruptible power supply (UPS) maintenance bypass mode switching device. This UPS maintenance bypass mode switching device includes a mechanical locking structure, and at least one switching component is connected to the rear end of the structure. The contacts of each switching component are connected to at least one dry contact of the rack-mounted UPS for maintenance mode, ensuring that the UPS can achieve self-protection through the linkage function during maintenance mode operation, preventing damage to the UPS equipment and customer equipment due to inconsistent input power standards.

[0021] In one possible implementation, some or all of the rack-mounted uninterruptible power supply shares the battery pack.

[0022] The aforementioned integrated power distribution cabinet allows some or all uninterruptible power supplies (UPS) to share battery packs. Each UPS does not require a separate battery pack, adopting a shared battery mode. This approach can improve the UPS's power supply time, increase battery utilization, and reduce redundancy. On the other hand, it can enhance system reliability. For example, centralized management of battery packs facilitates monitoring and maintenance, reduces the risk of UPS failure due to battery pack malfunctions, and facilitates maintenance and modifications without affecting the overall power supply, ensuring business continuity.

[0023] In one possible implementation, the power distribution management module further includes one or more of the following components: a mains input port for connecting to mains power, a multi-channel cooling module power supply input port, a multi-channel uninterruptible power supply power distribution input and output port, a main input configuration meter, a fuse component, a monitoring sensor for monitoring mains power parameters, and a surge protector for providing lightning protection.

[0024] In one possible implementation, the monitoring device includes one or more of the following: a rack-mounted monitoring host, a monitoring display screen, a network management unit, and a video management unit;

[0025] The rack-mounted monitoring host is used to monitor the status of each device in the integrated power distribution cabinet;

[0026] The monitoring display screen is used to display the status of each device in the integrated power distribution cabinet and to enable human-machine interaction with the user;

[0027] The network management unit is used to provide data reception and forwarding for the network devices in the integrated power distribution cabinet;

[0028] The video management unit is used to monitor and / or remotely monitor the operational safety status of the integrated power distribution cabinet in real time.

[0029] The aforementioned integrated power distribution cabinet integrates monitoring equipment. This equipment is powered by the power distribution management module inside the integrated power distribution cabinet. On the one hand, it can ensure power redundancy and realize uninterrupted power supply for monitoring equipment. On the other hand, it can save external dedicated equipment and cables, save costs, and facilitate on-site installation and maintenance.

[0030] In one possible implementation, the power distribution management module further includes an emergency management port for providing power to the emergency cooling module in the integrated power distribution cabinet and the emergency cooling modules in other cabinets in the tiered data center, and for controlling the operating status of the emergency cooling module in the integrated power distribution cabinet and the emergency cooling modules in other cabinets in the tiered data center.

[0031] In one possible implementation, the emergency cooling module includes at least: an air inlet side emergency fan module and an air outlet side emergency fan module;

[0032] The air intake emergency fan module is located at the bottom of the front door of the integrated power distribution cabinet, and the air outlet emergency fan module is located inside the top plate of the rear door of the integrated power distribution cabinet.

[0033] The aforementioned integrated power distribution cabinet integrates the power supply and control of emergency fans for all cabinet equipment, achieving centralized control and centralized power supply. This eliminates the need for external dedicated equipment, control methods, and fan power supply cables, saving costs and facilitating on-site installation and subsequent maintenance.

[0034] Secondly, this application provides a tiered data center, which includes: information technology (IT) equipment and at least one integrated power distribution cabinet provided in the first aspect of this application. The integrated power distribution cabinet is connected to the mains power supply to provide uninterrupted power to the IT equipment in the tiered data center. Attached Figure Description

The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0043] In the following text, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] Before introducing the integrated power distribution cabinet and row-level data center provided in the embodiments of this application, the technical background of the embodiments of this application will be described in detail for ease of understanding.

[0045] With the rapid development of technologies such as cloud computing, big data, and artificial intelligence, the related supporting infrastructure is also constantly developing and iterating. Among them, the power distribution system of data centers is also developing in tandem, and data centers are placing higher demands on the reliability and security of the power supply and distribution system.

[0046] Currently, the modularity and high integration of power distribution cabinets in data centers are mainly reflected in the complete power distribution function from the mains power through uninterruptible power supplies and busbars to IT equipment or cooling units. However, the system integration is still not high, and external related components are usually required to realize comprehensive power distribution functions. Moreover, existing power distribution cabinets mainly consider product structure and wiring safety, and basic electrical safety designs such as short circuits, overloads, grounding, and insulation. They lack safety and protection functions in terms of emergency, abnormal, misoperation, and electrical equipment protection, which poses safety hazards and risks.

[0047] In view of this, the embodiments of this application provide an integrated power distribution cabinet and a row-level data center. Monitoring equipment, a power distribution management module, an emergency cooling module, and multiple rack-mounted uninterruptible power supplies are installed in the cabinet. The power distribution management module is connected to the mains input to provide power input to the multiple rack-mounted uninterruptible power supplies and the cooling equipment in the row-level data center. The output ports of the multiple rack-mounted uninterruptible power supplies are connected to the output busbar, which can supply power to the AC and DC power devices in the integrated power distribution cabinet. Thus, comprehensive power distribution function is achieved without the need for external related components, improving the integration of the power distribution cabinet.

[0048] It should be noted that the row-level data center mentioned in the embodiments of this application refers to a modular and pre-configured data center deployment mode, which integrates the key infrastructure of the data center (such as racks, power supply and distribution, cooling, monitoring and management, etc.) into a standardized module with "a row of racks" as the basic unit.

[0049] After introducing the background technology of the embodiments of this application, the integrated power distribution cabinet provided by the embodiments of this application will be described in detail below with reference to specific embodiments.

[0050] See Figure 1As shown, it is a structural schematic diagram of the integrated power distribution cabinet in the embodiment of this application. The integrated power distribution cabinet provided in the embodiment of this application includes: cabinet 11, monitoring equipment 12, power distribution management module 13, emergency cooling module 14, and multiple rack-mounted uninterruptible power supplies 15.

[0051] The cabinet 11 includes front and rear glass doors, side panels (the side panels are removable), cabinet racks, U-shaped support columns, etc., and the top supports busway installation.

[0052] The monitoring equipment 12, power distribution management module 13, emergency cooling module 14, and multiple rack-mounted uninterruptible power supplies 15 are all integrated and installed inside the cabinet 11.

[0053] The power distribution management module 13 is connected to the mains power input and provides power input to multiple rack-mounted uninterruptible power supplies 15 and cooling equipment in the row-level data center. The output ports of the multiple rack-mounted uninterruptible power supplies 15 are connected to the output busbar, which supplies power to AC and DC electrical equipment in the integrated power distribution cabinet.

[0054] The monitoring equipment 12 includes one or more of the following: rack-mounted monitoring host, monitoring display screen, network management unit, and video management unit.

[0055] The integrated power distribution cabinet includes a rack-mounted monitoring host for monitoring the status of each device within the cabinet; a monitoring display screen for displaying the status of each device within the cabinet and facilitating human-machine interaction; a network management unit for providing data reception and forwarding for network devices within the cabinet; and a video management unit for real-time monitoring and / or remote monitoring of the operational safety status of the integrated power distribution cabinet.

[0056] The integrated power distribution cabinet provided in this application embodiment can realize the monitoring and management functions of power and environmental equipment and the local human-machine interaction display function through the monitoring device 12. It can realize the access of devices such as web access, digital input and output, analog input and output, sensors, uninterruptible power supply, cooling unit and power distribution management module, etc., to meet the networking requirements of various communication methods and the needs of different users.

[0057] Specifically, the network management unit can provide data reception and forwarding for network devices in the integrated power distribution cabinet, improving network performance and enabling device management and communication functions. Simultaneously, the network device management unit can provide power input for rack-level intelligent monitoring and access control systems, improving the security and ease of installation of access control equipment, replacing existing serial port-type intelligent access control equipment, and solving complex on-site wiring and setup issues (eliminating power and communication wiring, address settings, etc.). Power supply and communication are achieved through network devices, enabling rapid deployment and cost savings.

[0058] The video management unit can be used for real-time monitoring and / or remote monitoring of the operational safety status of the integrated power distribution cabinet, reducing labor costs, and can also achieve functions such as security protection (monitoring equipment against theft and damage), data center environment monitoring, equipment fault location, and security incident evidence collection.

[0059] The emergency cooling module 14 includes at least an air inlet side emergency fan module and an air outlet side emergency fan module, and each fan module may include multiple sets of fans. The air inlet side emergency fan module is located at the bottom of the front door of the distribution cabinet, and the air outlet side emergency fan module is located inside the top panel of the rear door of the distribution cabinet.

[0060] In practice, the power distribution management module also includes an emergency management port, which can not only provide power to the emergency cooling module in the integrated power distribution cabinet and control the operating status of the emergency cooling module in the integrated power distribution cabinet, but also provide power to the emergency cooling modules in other cabinets (such as server cabinets) in the tiered data center and control the operating status of the emergency cooling modules in other cabinets in the tiered data center.

[0061] For example, if the number of high temperature alarms in the integrated power distribution cabinet and / or other cabinets exceeds the preset number (which can be flexibly set according to the actual situation, such as 1), the emergency management port can be linked through monitoring to supply power to the corresponding emergency cooling module, so that all emergency fans can be turned on to provide temporary cooling, so that customers or maintenance personnel can arrive on site to troubleshoot and solve problems.

[0062] In practical applications, integrated distribution cabinets also include one or more of the following components: multiple load output ports for connecting load devices, and intelligent lighting for providing illumination. This intelligent lighting can provide different colors of light according to different states of the distribution cabinet; for example, it provides a first color of light when the distribution cabinet is operating normally, a second color of light when the distribution cabinet is under maintenance, and a third color of light when the distribution cabinet malfunctions.

[0063] It should be noted that the DC power equipment in the integrated power distribution cabinet provided in this application embodiment includes, but is not limited to: the monitoring display screen in the monitoring equipment 12, intelligent lighting, various monitoring sensors inside the power distribution cabinet, the main input configuration meter (set in the power distribution management module 12), relays (such as the emergency stop relay and anti-backflow relay in this application embodiment), and switch components (switch components connected to the mechanical locking structure), etc. The AC power equipment includes, but is not limited to: the rack-mounted monitoring host, video management unit, network management unit, and emergency cooling module 14 in the monitoring equipment 12.

[0064] The integrated power distribution cabinet provided in this embodiment can provide uninterrupted AC power supply for AC electrical equipment. The uninterruptible power supply backend of the AC power source can ensure the power supply quality and continuity of AC electrical equipment. At the same time, there is no need to configure a separate power distribution unit to supply power, which saves costs and reduces system configuration complexity, and solves the problem of discontinuous power supply to equipment.

[0065] In specific implementation, the power distribution management module 13 also includes one or more of the following components: a mains input port for connecting to the mains power, a multi-channel cooling module power supply input port, a multi-channel uninterruptible power supply power distribution input and output port, a main input configuration meter, a fuse component, a monitoring sensor for monitoring mains power parameters, and a surge protector for providing lightning protection.

[0066] In practical applications, the three-way power supply input for the cooling module can achieve cooling redundancy; the surge protector can be a surge protector with surge protection alarm fault output, so as to identify the working status of the surge protector in a timely manner, and resist lightning strike damage to equipment, protect the power grid and electrical equipment, improve the reliability of the power supply system, and ensure personnel safety; the power distribution input and output of multiple uninterruptible power supplies achieve N+1 redundancy of the system, improve the operational safety of the system, and the power distribution input of multiple uninterruptible power supplies includes controllable on / off function (such as the anti-backflow protection function mentioned in the following embodiments of this application), so as to realize the control of abnormal scenarios and realize equipment protection.

[0067] Considering the integrated distribution cabinets in related technologies, the main considerations are product structure and wiring safety, as well as basic electrical safety designs such as short circuits, overloads, grounding, and insulation. However, they lack safety and protection functions in areas such as emergency response, abnormal operation, misoperation, and electrical equipment protection. They also lack certain safety protection measures. Therefore, there are safety hazards and risks under abnormal conditions, which can affect equipment stability, operation and maintenance costs, and personal safety.

[0068] This application embodiment adds emergency power outage function, backflow prevention function, and uninterruptible power supply automatic switching to maintenance bypass mode function in maintenance mode to the integrated power distribution cabinet. The above three functions will be described below with reference to specific embodiments.

[0069] 1. Power-off function in emergency situations.

[0070] like Figure 2 As shown, the integrated power distribution cabinet provided in this application embodiment also includes: an emergency stop switch 20, an emergency stop relay 21, and a first shunt trip unit 22 whose first terminal is connected to the main input circuit breaker 23 in the power distribution management module 12.

[0071] Emergency stop switch 20 is connected to the control contacts of emergency stop relay 21 to respond to the user's emergency stop operation and control the operation of the emergency stop relay 21 contacts.

[0072] The emergency stop relay 21 is connected to the second terminal of the first shunt trip unit 22 and the emergency stop dry contacts of multiple rack-mounted uninterruptible power supplies (UPS). When its own control contacts actuate, it triggers the first shunt trip unit 21 to disconnect the main input circuit breaker and simultaneously controls the emergency stop dry contacts of the multiple UPS to be open, thus disconnecting the output of the multiple UPS. The emergency stop relay 21 can be powered by the DC power supply port in the power distribution management module.

[0073] Specifically, under normal operating conditions of the integrated power distribution cabinet, the emergency stop switch 20 is in the open state, the coil of the emergency stop relay 21 is not energized, the control contact of the emergency stop relay 21 does not operate, the contact of the first shunt trip unit 22 connected to the main input circuit breaker 23 is open, the coil of the first shunt trip unit 22 does not operate, the main input circuit breaker 23 is closed and operating normally, and at the same time, the remote emergency stop dry contacts of each uninterruptible power supply are in the closed state, and the uninterruptible power supply is operating normally inverting.

[0074] In the event of an emergency shutdown, pressing the emergency stop switch 21 closes the switch contacts, energizing the coil of the emergency stop relay 21. The contacts of the emergency stop relay 21 actuate (normally open contacts close, normally closed contacts open), closing the first shunt trip unit 22 connected to the main input circuit breaker 23. This actuates the coil of the first shunt trip unit 22, triggering the actuator and causing the main input circuit breaker 23 to open. Simultaneously, the remote emergency stop dry contact connected to the uninterruptible power supply (UPS) opens, immediately shutting down the rectifier, inverter, charger, and static bypass, and rapidly cutting off power to the loads (including inverter and bypass outputs). The battery also stops charging or discharging. The entire system achieves a total input power outage (air conditioning power outage), an uninterruptible power supply output power outage, and a shutdown of all loads, thus shutting down the entire data center system.

[0075] The integrated power distribution cabinet provided in this application embodiment has an external emergency stop switch 20 and an internal integrated control circuit of a first shunt trip unit 22 and an emergency stop relay 21. This ensures that in abnormal emergency situations, such as in the event of a fire or electrical fault, the power supply can be centrally cut off by pressing the emergency stop switch to prevent further damage.

[0076] II. Backflow prevention protection function.

[0077] The integrated power distribution cabinet provided in this application embodiment further includes: at least one anti-backflow module, and each anti-backflow module is connected to at least one rack-mounted uninterruptible power supply.

[0078] In practice, each anti-backflow module can be connected to a rack-mounted uninterruptible power supply, or each anti-backflow module can be connected to multiple rack-mounted uninterruptible power supplies. This application does not limit this.

[0079] like Figure 3 As shown, the anti-backflow module includes: an anti-backflow relay 30 and a second shunt trip unit 31. The control contact of the anti-backflow relay 30 is connected to the output dry contact of the rack-mounted uninterruptible power supply (UPS). The first terminal of the second shunt trip unit 31 is connected to the anti-backflow relay 30, and the second terminal is connected to the input circuit breaker 32 of the rack-mounted UPS.

[0080] When the output dry contact of the rack-mounted uninterruptible power supply is closed, the anti-reverse current relay 30 controls the contact to operate, thereby triggering the second shunt trip unit 31 to disconnect the input circuit breaker 32 of the rack-mounted uninterruptible power supply.

[0081] Specifically, the input circuit breaker 32 of the uninterruptible power supply is equipped with a second shunt trip unit 31. Since the operating current of the second shunt trip unit 31 is large, the current of the output dry contact of the uninterruptible power supply is insufficient to make the second shunt trip unit 31 operate. Therefore, an anti-backflow relay 30 is added. The anti-backflow relay 30 is powered by the DC power supply port of the power distribution management module.

[0082] In the event of an abnormal or dangerous power supply or energy source, the output dry contact of the uninterruptible power supply closes, the coil of the anti-reverse current relay 30 is energized, and the contacts close. At this time, the electromagnetic coil of the second shunt trip unit 31 is energized, and the second disconnect trip unit 31 operates, causing the input circuit breaker 32 of the uninterruptible power supply to open, thereby achieving anti-reverse current protection.

[0083] The integrated power distribution cabinet provided in this application embodiment integrates a second shunt trip unit 31 and a backflow prevention relay 30 control circuit for the internal uninterruptible power supply input, so as to avoid the current flowing back to the input port of the uninterruptible power supply when there is an abnormal or dangerous power or energy, which could cause the risk of accidental electric shock to personnel.

[0084] 3. The function of automatically switching to maintenance bypass mode.

[0085] The integrated power distribution cabinet provided in this application embodiment also includes: an uninterruptible power supply maintenance bypass mode switching device that is linked to the maintenance bypass switch of the integrated power distribution cabinet.

[0086] like Figure 4As shown, the uninterruptible power supply (UPS) maintenance bypass mode switching device includes: a mechanical locking structure 40 that is displaced when the maintenance bypass switch is activated, and at least one switching assembly 41 connected to the mechanical locking structure. The switching assembly 41 can be a micro-switch, which can be powered by the DC power supply port of the power distribution management module. The contacts of each switching assembly 41 are connected to at least one maintenance mode dry contact of the rack-mounted UPS.

[0087] The mechanical locking structure 40 is used to control the switch assembly 41 to be in a first state when the maintenance bypass switch is open, in which case the dry contact of the rack-mounted uninterruptible power supply in maintenance mode is disconnected; when the maintenance bypass switch is closed, the switch assembly 41 is controlled to be in a second state through displacement linkage, in which case the dry contact of the rack-mounted uninterruptible power supply in maintenance mode is connected, and the rack-mounted uninterruptible power supply switches to maintenance bypass mode.

[0088] In practical applications, a mechanical locking structure 40 is added to the maintenance bypass switch of the integrated power distribution cabinet. The mechanical locking structure 40 is locked in position to prevent misoperation from causing a phase difference or voltage mismatch between the uninterruptible power supply and the mains output, which could lead to severe inrush current or even short circuit, damaging the uninterruptible power supply or load equipment.

[0089] A micro-switch (i.e., switch assembly 41) is added to the rear end of the mechanical locking structure 40. The micro-switch is always in the normally closed mode, and the mechanical locking structure 40 always presses the micro-switch.

[0090] When maintenance of the uninterruptible power supply (UPS) is required, the maintenance personnel need to manually operate the mechanical locking structure 40, for example, by pushing it horizontally. At this time, the mechanical locking structure 40 is disengaged, the micro switch is opened, and the UPS maintenance mode dry contact connected to the micro switch is closed. The UPS automatically switches to maintenance bypass mode, thereby ensuring that the power quality parameters of the mains power and the UPS input and output are consistent, preventing damage to the UPS or load, and providing equipment protection.

[0091] The integrated power distribution cabinet provided in this application embodiment has an internal maintenance switch with an integrated mechanical locking structure 40. The rear end of this structure is connected to at least one switch assembly 41. The contacts of each switch assembly 41 are connected to at least one dry contact of the maintenance mode of the rack-mounted uninterruptible power supply, ensuring that the uninterruptible power supply can be self-protected through the linkage function during maintenance mode operation, preventing damage to the uninterruptible power supply equipment and customer equipment due to inconsistent input power supply standards.

[0092] In the integrated power distribution cabinet provided in this application embodiment, some or all rack-mounted uninterruptible power supplies (UPS) share a battery pack to jointly provide backup power, solving the problem in related technologies where UPS and batteries are independently equipped and battery backup resources cannot be shared, thus maximizing the backup function of the battery. This shared battery pack can be used in parallel to meet load requirements and redundancy, ensuring that the integrated power distribution cabinet can provide uninterrupted power and operation in abnormal situations, protecting the safety of customer equipment and resources.

[0093] The integrated power distribution cabinet provided in this application embodiment allows some or all uninterruptible power supplies (UPS) to share a battery pack. Each UPS does not need to be configured with a separate battery pack, adopting a shared battery mode. In this way, on the one hand, the power supply time of the UPS can be improved, the battery utilization rate can be increased, and redundancy can be reduced. On the other hand, the system reliability can be enhanced. For example, centralized management of the battery pack facilitates monitoring and maintenance, reduces the risk of UPS failure due to battery pack failure, and facilitates maintenance and modification without affecting the overall power supply, ensuring the continuity of business.

[0094] Through the detailed description of the integrated power distribution cabinet provided in the embodiments of this application above, the integrated power distribution cabinet provided in the embodiments of this application has high integration and good compatibility. The centralized power distribution management module adopts an integrated installation design, which is integrated with the whole cabinet, and the installation is reliable.
