The function of the following () parts is to help with oil return.
Correct Answer:
C
Explanation
An oil trap is a component in power distribution systems that captures oil from transformers and other equipment to prevent environmental contamination and aid in oil return processes. This is fundamental knowledge about power distribution equipment used in data center facilities. Other parts of the system serve different functions like insulation or cooling rather than oil return.
MCB Circuit breakers can be divided into different tripping characteristics B, C, D, Z, K Level, for IT For load, you should use ____________ class Tripping characteristics.
Correct Answer:
A
Explanation
MCB circuit breakers use different tripping characteristics for different loads. Class C is the standard choice for IT equipment because it handles moderate inrush currents typical of computer hardware. Class B trips too quickly for IT loads, while Class D, Z, and K are designed for other applications like motors or high inrush equipment. Understanding tripping characteristics is essential for proper power distribution design.
UPS Common working modes are ____________ .
Correct Answer:
A
Explanation
UPS systems operate in three main modes. Main circuit inverter mode powers the load from the battery through an inverter when mains power fails. Static bypass mode switches the load directly to the mains when the inverter cannot support it. Battery mode refers to the system running on battery power. These three modes cover all normal operational states of a UPS in a data center.
MCB The main functions of the circuit breaker include circuit breaker protection and overload protection.
Correct Answer:
A
Explanation
A 12V battery is constructed by connecting six 2V cells in series. When cells are connected in series, their voltages add together, so 6 cells multiplied by 2V per cell equals 12V total. This is a fundamental principle of battery construction and applies to both lead-acid and lithium-ion battery technologies used in data center power systems.
The function of the following ____________ components is to help return oil.
Correct Answer:
A
Explanation
Personnel working at heights must wear safety belts that meet established safety standards and use them correctly according to manufacturers' guidelines. This is a core requirement of work safety and accident prevention. Using safety equipment under supervision ensures that climbing personnel, such as those working on cooling systems or cable installations, are protected from falls and serious injuries during data center construction and maintenance.
At present, storage batteries are mainly installed in racks and cabinets in data centers.
Correct Answer:
A
Explanation
R410A is a refrigerant used in air conditioning systems. When sprayed directly onto skin, it can cause severe frostbite and tissue damage in seconds because the rapid evaporation of the liquid removes heat from the skin extremely quickly. This extreme cold can cause temporary numbness followed by deep muscle and tissue damage, resulting in necrosis at the affected site. Proper handling and safety precautions with refrigerants are essential for personnel working with cooling systems.
In the dynamic ring monitoring system, it can be used to store high-definition images and provide large-scale storage medi
a. The equipment used for long-term storage of video recording is ____________ .
Correct Answer:
A
Explanation
A network hard disk video recorder (NVR) is specialized equipment designed for long-term storage and retrieval of high-definition video in monitoring systems. NVRs work with IP-based cameras and can store massive amounts of video data on large hard drives. This makes them the appropriate choice for dynamic ring monitoring systems that need extended recording capabilities. Other storage solutions either lack the capacity or the video optimization that an NVR provides.
