info@upspowersupply.netSome Common Sense about UPS
Q: What a role does the UPS play?
A: With the development of information and technology, the network has become an indispensable part of people’s life and work. Reliability of power supply of the digital machine room constituting the network has become a linchpin. The UPS emerges to cope with the need of uninterruptible power supply. Voltage stabilization, filtering and no interruption constitute three basic functions of the UPS.
Q: Is the UPS better at carrying the inductive load or carrying the capacitive load? Why?
A: The UPS is designed according to the inductive load, so to carry the inductive load is its intrinsic duty. The capacitor of the UPS whose inverter output terminals are connected in parallel exists for filtering. Besides, it can trade off the induction component in the load.
Q: What is the role of the statistic transfer switch (STS), location-based synchronizer (LBS) and double bus, respectively
A: The STS functions to transfer the input current of two circuits. The LBS functions to synchronize two groups of UPS, aiming at turning the switching period of the STS to be zero. The role of the double bus is to provide the redundant power source with the electric equipment.
Q: What are advantages and disadvantages of the power frequency machine and the high power machine? Can the latter be replaced by the former?
A: Disadvantages of the UPS with the frequency power machine include a small power factor, a large power, a small efficiency, a large volume, clumsiness, a high price and a low reliability. On the contrary, its advantages are mainly reflected as convenience of manufacturing. Particularly, no significant influence will be caused under the manual operation mode. Meanwhile, there is not a high requirement of consistency.
As to advantages of the UPS with the high-frequency power, there is a high power factor, a small power consumption, a high efficiency, a small volume, convenience and high reliability. However, its requirement of the production means and consistency is high.
Q: What is the active power? What is the nonactive power?
A: The active power refers to the power used by the load for working, such as shining of the bubble drives the circuit to work. After doing work, the power is dissipated into the air, which will not return. The nonactive power refers to the power stored in the energy storage device, which can be transferred into the active power.
Q: What is the capacity unit of the accumulator? What is its implication?
A: The capacity unit of the battery is ampere-hour, abbreviated as AH. It denotes the capacity discharged until the end of the discharge under the constant current or power under the condition of the designated discharge rate. Take a battery with the discharge rate as 10 and capacity as 100AH for example. Use the discharge current 10A constant vurrent to discharge for 10H, and the volume discharged is 100AH.
Q: Is there lightning protection for the UPS?
A: The UPS can choose the C-grade lightning protection, which can be divided into two kinds, including the lightning protection with the priority of load protection and the lightning protection with the priority of power supply protection. However, the lightning protection does not play an important role. The lightning protection installed by the UPS can serve as the provincial level-a lightning protection in the power distribution cabinet, but the lightning protection device cannot yet be omitted in power distribution.
Q: Can the overload resistance of the UPS be strengthened after being installed with the isolation transformer?
A: No. The UPS with a slow response will covert to the bypass work mode after overloading. After the overload is normal, the UPS will resume its rectification and inversion after the load becomes normal again. We should upgrade the UPS capacity to satisfy the need for an increasing load.
