Description

Technical Field

[0001] This utility model relates to the field of UPS power cabinet technology, and in particular to an intelligent UPS power cabinet. Background Technology

[0002] Uninterruptible power supply (UPS) systems, as core equipment to ensure continuous power supply to critical loads, are widely used in data centers, finance, communications, industrial control and other fields. Traditional UPS power cabinets mainly focus on basic power conversion and backup functions, and their system architecture and physical structure have many inherent limitations.

[0003] Firstly, in terms of thermal management, traditional server racks mostly employ passive cooling solutions based on fixed-speed fans and simple ventilation holes. This solution cannot dynamically adjust according to the actual operating temperature of the equipment inside the rack, resulting in low cooling efficiency. Insufficient cooling easily leads to heat accumulation inside the rack, especially under high load or high temperature environments, endangering the lifespan and reliability of power electronic devices (such as IGBTs) and batteries; while excessive cooling leads to energy waste. At the same time, the humidity inside the rack cannot be effectively monitored and controlled, and a humid environment can easily cause safety hazards such as condensation and short circuits.

[0004] Secondly, regarding system integration and status monitoring, traditional UPS cabinets typically have independently deployed power distribution units, rectifier / inverter power conversion modules, and battery banks. Status information (such as voltage, current, and temperature) between these units is not comprehensively collected, and there is a lack of unified hardware interfaces for data integration and interaction. Maintenance personnel struggle to monitor the overall system health in real time, including individual battery cell voltage balance, state of health (SOH), and the continuity of power distribution circuits. Fault warning capabilities are insufficient, and maintenance often relies on periodic manual on-site inspections, resulting in delayed responses and an inability to provide early warnings and remote intervention.

[0005] Therefore, an intelligent UPS power cabinet is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to propose an intelligent UPS power cabinet to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides an intelligent UPS power cabinet, including a cabinet body, a front cabinet door, and a rear cabinet door. The front cabinet door is movably connected to the front of the cabinet body, and a tempered glass window is fixedly connected to the front cabinet door. The rear cabinet door is movably connected to the back of the cabinet body, and the rear cabinet door is a double-opening type. A cable tray is fixedly connected to the inside of the cabinet, and shelves are fixedly connected to several points on the cable tray. Air inlets are provided on both sides and the rear door of the cabinet. A fan is fixedly connected to the bottom of the top panel of the cabinet, with the air outlet of the fan facing upward. A power distribution mechanism is fixedly connected to the front of the cabinet interior, a power conversion mechanism is fixedly connected to several shelves of the cabinet, and a battery is fixedly connected to several shelves of the cabinet. An Internet of Things (IoT) module is fixedly connected to one layer of the cabinet. The IoT module is electrically connected to the power distribution mechanism, the power conversion mechanism, and the battery. The input end of the IoT module is fixedly connected to several temperature and humidity sensors, which are attached to the back of the power distribution mechanism. The output end of the IoT module is connected to a fan, and the IoT module has a built-in 5G module.

[0009] Preferably, in any of the above embodiments, the cabinet is made of multiple cold-rolled steel plates riveted together, and the cable tray is made of aluminum alloy.

[0010] The above technical solution is adopted as follows: Power distribution mechanism: Input end: one single-phase mains power input of 25A, one UPS maintenance bypass, one data acquisition system circuit breaker, and several distribution circuit breakers. Surge current: nominal discharge current Isn (8 / 20μs): 40KA; maximum discharge current Imax (8 / 20μs): 80KA.

[0011] Power conversion mechanism: It adopts advanced power conversion technology, optimizes circuit design and introduces intelligent control system, which greatly improves conversion efficiency and effectively reduces energy loss.

[0012] Battery structure: The previously independent batteries have been optimized into battery modules, which improves battery safety and makes it easier for the conversion system to monitor the battery and improve the rationality of charging and discharging.

[0013] Intelligent Structure: Data from the power cabinet is connected to an IoT module and transmitted to the cloud using IoT technology. Users can view the power cabinet's status (system conversion efficiency, battery voltage and capacity, cabinet temperature and humidity information, status of each distribution circuit breaker, etc.) via a mobile app. Historical records can be used to query operating data and fault information, and early warning information can also be pushed via the app.

[0014] Heat dissipation and dehumidification mechanism: Combining intelligent strategies, temperature and humidity sensors monitor the temperature and humidity inside the cabinet in real time and send the data to the IoT module. The IoT module turns the fan on and off and controls the fan's operating power based on the temperature and humidity. By detecting the temperature and humidity inside the cabinet, it precisely adjusts the heat dissipation and dehumidification (turning the fan on and off and adjusting the fan's operating power) to ensure that the equipment is in a good operating environment.

[0015] Cabinet dimensions: 2250mm*600mm*800mm, front and rear metal / vacuum glass doors, frame material is 2.0mm cold-rolled steel plate, single cabinet structure is sturdy, assembly is consistent and interchangeable, and fasteners are secure. Open cable trays allow for comprehensive control of cabling quality.

[0016] Leveraging cutting-edge technologies such as the Internet of Things and big data, we have developed a system for real-time monitoring of system operation status via local terminals and a mobile app. Precise heat dissipation strategies can accurately regulate the temperature within the power cabinet, ensuring a optimal operating environment for the equipment. Early warning strategies can predict equipment problems in advance, improving intervention capabilities and reducing system failure rates.

[0017] Working principle: Mains power supplies the power conversion section through the distribution section. The power conversion section uses the mains power to charge the battery, while simultaneously regulating and converting it into stable electrical energy. This stable electrical energy is then distributed to the electrical equipment through the distribution section. The intelligent section integrates information from all parts and performs reverse control operations, achieving distributed control and centralized management.

[0018] Preferably, in any of the above solutions, the upper and lower ends of the cable tray are connected to the cabinet by screws, and the air inlet is composed of a large array of densely arranged strip holes.

[0019] Preferably, in any of the above schemes, the power distribution mechanism includes an input terminal, an output terminal, a bypass section, and a protection section, which is responsible for mains power input distribution, load output control, and bypass switching in case of fault. The main circuit of the power distribution mechanism is connected to the input terminal of the power conversion mechanism, which converts AC power into DC power. On the one hand, the power distribution mechanism charges the battery through its charging circuit, and on the other hand, it supplies power to the inverter's DC bus.

[0020] Preferably, in any of the above schemes, the DC power output by the power conversion mechanism is connected to the positive and negative terminals of the battery after passing through the charging protection circuit of the power distribution mechanism, thereby realizing battery charging.

[0021] Preferably, in any of the above schemes, when the battery is discharging, it is connected to the inverter input terminal through the discharge circuit of the power distribution mechanism. The inverter converts the DC power into AC power, which is then delivered to the load through the output power distribution unit.

[0022] Preferably, in any of the above schemes, the IoT module is electrically connected to the power distribution mechanism, the power conversion mechanism, and the battery via a dual path of signal line + power line.

[0023] The specific working principle of the IoT module is as follows: (Regarding the power distribution mechanism:) Signal acquisition: Connect voltage / current sensors to the input power distribution unit to monitor the mains input quality (voltage fluctuation, frequency deviation); connect to the output power distribution unit to monitor the load output voltage / current / power; connect to the bypass unit to monitor the status of the bypass contactor (on / off / fault).

[0024] Control interaction: Remotely operate the input circuit breaker to open and close, and switch the bypass contactor through the control interface (such as relay output) to achieve remote fault isolation or mode switching.

[0025] With power conversion mechanisms: Rectifier monitoring: Collects rectifier input / output voltage, current, and temperature; monitors rectification efficiency and over-temperature alarms. Inverter monitoring: Collects inverter output waveform, frequency, and load rate; monitors inverter stability and harmonic content.

[0026] Battery Parameter Acquisition: Connects to the Battery Management System (BMS) to monitor individual battery cells / total voltage, charge / discharge current, temperature, and State of Charge (SOC) / State of Health (SOH) in real time, enabling overcharge / over-discharge / over-temperature protection. Balancing Control: Achieves active balancing between individual battery cells via the BMS interface, extending battery life.

[0027] Protection linkage: The input / output circuit breakers of the power distribution unit are linked with the IoT module. When an overcurrent / short circuit is detected, the IoT module triggers the circuit breaker to trip and reports a fault code at the same time. When the battery overheats, the IoT module triggers charging current limiting or discharging cut-off to prevent thermal runaway.

[0028] Mode switching coordination: When the mains power is interrupted, the IoT module detects the abnormal input voltage and automatically triggers the power distribution mechanism to switch to battery discharge mode, and the inverter starts to supply power; when the mains power is restored, it automatically switches back to the main circuit charging mode and updates the battery SOC synchronously.

[0029] Remote management: The IoT module reports operational data to the cloud platform via 5G, supporting remote parameter configuration (such as output voltage adjustment), fault diagnosis (such as rectifier fault location) and firmware upgrades, enabling unattended operation and maintenance.

[0030] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This intelligent UPS power cabinet boasts highly efficient and precise heat dissipation and dehumidification capabilities. Dense strip-shaped air inlets on both sides and the rear door, combined with an exhaust fan fixed to the bottom of the top panel, form a highly efficient active airflow system. Specifically, temperature and humidity sensors attached to key heat sources such as the back of the power distribution unit collect data in real time, and the IoT module directly outputs control signals to the fans. Based on actual monitoring data, the fans can be precisely started and stopped, and their power adjusted, achieving precise temperature and humidity control based on hardware sensing and control. This effectively ensures that the internal equipment always operates in a favorable environment. It enables intelligent interconnection and collaboration at the hardware level: The IoT module, as an independent hardware entity, is directly electrically connected to all key components such as the power distribution mechanism, power conversion mechanism, and battery through dual paths of signal lines and power lines. This hardware interconnection allows it to directly collect physical parameters such as voltage, current, and temperature, and directly output control signals (such as controlling circuit breaker opening and closing, and fan start / stop power adjustment through relay interfaces). It realizes data interaction and linkage control between various hardware units, providing a physical basis for remote monitoring, fault early warning, and protection, and can achieve basic automatic response and protection without relying on external software.
