(Communication exchange: comparison and selection of medium and large UPS With the rapid development of the communication industry, various corresponding advanced communication and ancillary equipment are continuously produced. Today, the quality requirements of telecommunications equipment used in power supply grids are becoming more and more stringent, not only requiring normal power supply system output, but also ensuring good sine waves without any interference.
Various loads are connected to the mains power grid, which causes disturbance and pollution to the power grid, deteriorates the quality of the power supply network, affects the normal operation of the load equipment, and may cause unpredictable problems to the load equipment. The generation of UPS uninterruptible power supply and its ability to solve the harm caused by poor mains power quality to front-end equipment, such as power failure, voltage spike, voltage surge, frequency drift, harmonic interference, overvoltage and undervoltage, voltage fluctuation and noise voltage , showing its importance in the field of use.

There are many types of UPS in the current market, and their office modes are also various, which puts forward higher requirements on how to choose and configure an ideal UPS. In view of the importance of the load carried by the exchange bureau (station) in the communication industry and the stability and safety of the mains grid, this paper discusses the purchase of medium and large UPS and the types of UPS, office mode, capacity, parameter performance, battery and Capacity selection, wiring selection and other aspects have been described in detail.
1. Correctly choose the type of UPS
The current UPS can be divided into the following types: online, online interactive, backup and Delta conversion.)
