質問 # 56
Which of the following interfaces is used to connect the controller and the main control module of the unit?
正解：D
解説：
In Huawei precision cooling units, the LCD controller (human-machine interface) must exchange real-time operating data and commands with the unit's main control module while also receiving a stable low-voltage power supply. This connection is typically implemented as a low-voltage communication bus plus DC power, which is why the interface is identified as I2C/12V. The I2C portion provides the data channel used for status display, parameter viewing/setting (within permission scope), alarm presentation, and command delivery (such as mute, reset, or control enable actions). The 12 V portion supplies power to the controller so it can operate independently of high-voltage power circuits and remain safe to access during routine O&M. Interfaces like DP and USB are not used as the internal control link between the HMI and the main control board in this type of unit, and "SW" is not the designated controller-to-main-board interface in the standard wiring definition. Therefore, I2C/12V is the correct selection.
質問 # 57
Which of the following are the functions of the SmartLi 3.0 battery control unit (BCU)?
正解：A、B、C、D、E、F
解説：
In Huawei SmartLi 3.0, the BCU acts as the cabinet-level "brain" of the lithium battery system, coordinating measurement, control, protection, and communication. Itmanages and supervises BMUsinside the cabinet by collecting key operating data such as voltage, temperature, SOC, and SOH, and by aggregating module information for higher-level management. The BCU supportscharge/discharge managementby monitoring string current and controlling operating behaviors to keep the battery within safe electrical and thermal limits.
To ensure consistent performance across parallel strings and cabinets, it implementsintelligent voltage sharing and active current balancing, which helps equalize currents, improve utilization, and reduce uneven aging. For safety and reliability, the BCU providesfault diagnosis and protection, including handling events such as overvoltage, undervoltage, overcurrent, and overtemperature, and it can isolate abnormal loops when required. SmartLi 3.0 also incorporatesinternal short-circuit risk predictionas part of its safety strategy. Finally, group capacity testingis supported as a maintenance function to verify usable capacity and system health.
質問 # 58
Which of the following statements is false about the advantages of the free cooling solution for data centers?
正解：B
解説：
Free cooling is a mainstream energy-saving concept in data center cooling design, used to reduce chiller compressor runtime by leveraging low outdoor temperatures (air-side) or low cooling-water temperatures (water-side) during suitable seasons. Therefore, describing the technology as "not mature enough and should be used with caution" is the false statement when discussing its advantages. In practice, free cooling has broad industry adoption and is considered a proven approach when applied with correct engineering, such as proper filtration, anti-condensation control, heat exchanger selection, and automatic control strategies. Its advantage is that it can directly utilize the outdoor "cold source" to remove heat, which significantly reduces cooling power consumption compared with full mechanical refrigeration, improving overall energy efficiency and supporting lower PUE targets. It also makes full use of seasonal and day-night temperature differences: the system dynamically switches among free cooling, partial free cooling, and mechanical cooling to balance reliability and efficiency. The key point is maturity: the benefit of free cooling comes from well-established principles and widely implemented architectures, not experimental technology.
質問 # 59
The maintenance bypass switch cannot be turned on when the UPS5000-H works in normal mode.
正解：A
解説：
In UPS5000-H operation, normal mode means the load is supplied by the inverter, and the rectifier/charger maintains the DC link and batteries. The maintenance bypass switch (maintenance bypass breaker) is a mechanical isolation path intended to keep the load powered while the UPS is taken out of service for inspection or repair. Because it changes the power path and can create unsafe or unintended parallel paths if operated incorrectly, it is not permitted to simply close the maintenance bypass switch while the UPS is in normal mode. The correct O&M logic is to perform a controlled transfer first (typically transferring the load to static bypass with proper synchronization and confirmation that bypass power is healthy), and only then close the maintenance bypass switch so the UPS can be safely isolated. This prevents disturbance to the load, avoids synchronization/transfer hazards, and protects personnel from incorrect switching operations. Therefore, the statement is true in the sense of standard UPS5000-H operating procedure and safety interlock intent.
