requirement analysis

With the continuous development of the hospital management information system, the hospital network has also changed from the single service management in the past to the server cluster management in the present. It takes on the important tasks of network communication, information storage, consultation transmission, etc.; for example, the physiological parameters of patients collected every day reach billions of words of data, behind which there are many important information hidden. Once the power is cut off, it can't be saved , what it means to lose these data is self-evident. As soon as the power failure occurs in the network, it will cause loss to the hospital, so what kind of hospital UPS power solution should be well selected.

The level of medical system is rising rapidly, and the level of software and hardware construction is constantly rising. The informatization of medical system has become a consensus. Therefore, the power supply guarantee system of the hospital UPS power supply solution is gradually applied to the power supply of the hospital room and medical system.

Basic configuration scheme

The building data adopts 120kVA UPS power supply. One UPS input cabinet and one UPS output cabinet are configured. One set of switches shall be reserved for each input and output to be used for UPS expansion to two racks in the future. According to the requirements of electrical installations of buildings - Part 7-710: requirements for special installations or places - medical places, an output isolation transformer shall be configured at the same time of UPS output. The specific structure is shown in the figure.

Program advantages

Ubersch UPS power supply adopts the structural flexibility of modular design, which can realize n + 1, N + 2, N + 3, N + 4, N + 5 Module n + X redundancy, power supply system. At the same time, customers can also increase their spare redundancy capacity by ordering additional modules. The ups of ubersch series has the performance advantage of on-demand capacity expansion. It can be configured according to the current load. When the load of the machine room is expanded, the module can be directly hot inserted. The capacity expansion is flexible and convenient. The redundant power supply system can be expanded to 480KVA with one 20KVA module as the unit.

According to the site load demand, ubersch provides a more economical redundant configuration scheme of UPS power supply system. One 120kVA UPS power supply is adopted, which is composed of six 20KVA modules with a total power of 120kVA and module 5 + 1 parallel redundant system. TN-S distribution system is adopted at the output side, and the protection provided by the power supply system is adopted.

Ubersch has a 1kva-200kva series UPS product line, and its medical equipment UPS product power supply system includes single in single out, three in single out, three in three out; it can block the impact of abnormal power supply on the load, and ensure the stability of the output power supply, so that the load can run. Digital control technology is adopted to realize the function of parallel expansion and parallel redundancy, and provide flexible guarantee for power planning for users.
