Two, UPS design
2.1 overview
According to the technical requirements of the information center room, provide an uninterrupted communication system (UPS) product program.
2.2 UPS power distribution system
2.2.1 general description
* the power supply for the central room of the project adopts three-phase five wire system.
* the power supply for power equipment in the room is three-phase, five wire system and single-phase three wire system. Room air conditioning, new exhaust system, normal lighting, temporary repair socket, general office equipment, etc., are powered by municipal power. The equipment in the engine room, regional information equipment, emergency lighting, fire protection and security are all powered by UPS.
* strong and weak electrical systems are arranged separately and rationally designed. In the power room, the reasonable design, the total input, the power distribution cabinet, the city electricity output power distribution cabinet, the UPS output power distribution cabinet.
* the UPS system uses the Emerson Adapt series 10KVA UPS system as the main part of the uninterrupted power supply system, and the system backup time is designed according to the system full load delay time of 2 hours.
We this division centralized nearby power supply scheme, the first Rack frame design Emerson Rui style using Adapt system, the system can be directly installed in the equipment room cabinet near the column, greatly shorten the distance distribution system and load cabinet, cable laying and save expenses, further reduce power consumption, to achieve the
purpose of energy saving optimization; secondly provide the structure of the system more flexible, fully realized on-demand scalability without the need to invest a lot of infrastructure investment in advance, to protect the interests of users the maximum degree; again to routine maintenance and future expansion provides great convenience, reduce the difficulty of the work room management departments, improve work efficiency. All of the above advantages ensure the reliability and economy of the power supply and distribution system in the engine room.
2.3 Emerson Adapt modular UPS system
Feasibility analysis of 2.3.1 modular UPS system scheme
Because of its high reliability, easy expansion, easy installation and maintenance, energy saving and environmental protection, modular UPS system has become the future development trend of UPS, and we have adopted this kind of UPS system in this project.
* investment while developing
Modular UPS,
With a strong capacity to expand, you can achieve the edge of the development of investment on demand expansion requirements. According to our understanding, the user is not much use of existing equipment, modular UPS, without changing the existing room structure, can easily achieve expansion, ensure the reliability of the power supply system of the future.
* higher reliability
N+X is currently the most reliable power supply structure, N represents the total load required at least UPS number, X is representative of the redundant UPS number, which is the system can bear the fault UPS number, when X is larger, the reliability of the system will be higher. For example, one client has a total load of 32KVA, and a modular UPS is used as a N+1 redundancy design. The N is 2, the X is 1, and the redundancy level is 99.999%. You can also choose to do N+2 redundancy design, and its availability level is 99.99999%, so that users can improve the redundancy level according to the importance of the load.
* green energy saving
Using modular UPS, the power of UPS can be configured according to the actual situation of the existing load, so as to ensure the ideal matching of UPS and load, and achieve the best energy-saving effect.
Generally speaking, UPS is the most efficient under full load, but the lighter the load, the lower the efficiency. The two traditional UPS and UPS machine, the maximum load of up to 50%, according to statistics in most cases is not more than 40%, the load conditions of UPS efficiency are generally not more than 82%; if the use of modular UPS, such as 2+1 redundancy mode, the maximum load can reach 67%, the efficiency can be as high as 90% so, in terms of system efficiency, energy consumption, equipment utilization rate, investment protection and other aspects are the best. This design concept in environmental protection and energy saving is a good response to the current
state vigorously promote energy-saving emission reduction policy.
* modular UPS for easy handling, transportation and installation
Cabinet type traditional UPS as a whole, a single frame is relatively heavy, such as the capacity of the weight of 100KVA is about 1000kg, the size of more than 2m3, packaging, transportation, loading and unloading, the room door or aisle is small, lift truck is not enough, the floor plate can not support problems.
And the use of modular UPS, then the above problems will be resolved blade: 2 ~ 4 manpower that can fix the rack, 1~2 people can fix the module installation.
Traditional high-power UPS structure limits the use of vertical packaging and vertical transport, greatly limiting the choice of transport vehicles. And modular UPS system, because the module can be separately packaged, the rack can be horizontal packaging and transportation.
