Regarding the working logic of the low-voltage bus tie switch, which of the following descriptions is correct?
- A . When the two mains power inputs of the data center come from different substations, a bus tie switch cannot be installed at the low voltage level. A bus tie switch can only be installed at the low voltage level when the two mains power inputs of the data center come from the same substation.
- B . Assuming the data center has two mains power inputs, A and B, and a tie switch is installed at its low-voltage bus, then during normal operation, only any two of the following switches will be closed: the mains power input circuit breaker for line A, the mains power input circuit breaker for line B, and the bus tie switch.
- C . Assuming the data center has two mains power inputs, A and B, and a tie switch is installed at its low-voltage bus, then during normal operation, only one of the following switches will be closed: the mains power input circuit breaker for A, the mains power input circuit breaker for B, and the bus tie switch.
- D . Assuming the data center has two mains power inputs, A and B, and a tie switch is installed at its low-voltage bus, then during normal system operation, three switches can be closed: the mains power input circuit breaker for A, the mains power input circuit breaker for B, and the bus tie switch.

- A . The power transmission loss of a high-pressure oil pump is lower than that of a low-pressure oil pump.
- B . The switching between high-pressure oil pump and mains power is achieved through ATS, while the switching between low-pressure oil pump and mains power is achieved through centralized switching via integrated protection control switch.
- C . The upper capacity limit of a parallel system composed of high-pressure oil generators is higher than that of a low-pressure oil generator.
- D . High-pressure oil pumps have a stronger nonlinear load-carrying capacity than low-pressure oil pumps.
Regarding the segmented expansion of data center power distribution systems, which of the following statements is wrong?
- A . The phased expansion of the data center power distribution system requires the IT load capacity growth curve as input.
