Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For the purpose of understanding the embodiments of the present application, the technical terms referred to in the embodiments of the present application are briefly described as follows:
the communication power supply is a device which is specially used for providing direct current power supply for communication equipment, and the commonly used communication power supply adopts a power semiconductor device as a high-frequency conversion switch, and is isolated by a high-frequency transformer to form a-48V high-frequency switching power supply which converts alternating current into direct current. The communication power supply in the embodiment of the application can be a-48V high-frequency switching power supply.
The communication power supply system consists of units such as an alternating current distribution panel (optional), a high-frequency switch power supply panel, a direct current distribution panel (cabinet), a storage battery pack (cabinet) and the like. Each communication high-frequency switch power supply system at least comprises a high-frequency switch power supply screen and a storage battery pack, and is preferably provided with a direct current distribution screen.
UPS, i.e. an uninterruptible power supply, is a constant voltage and constant frequency power supply apparatus including an energy storage device (battery pack) and an inverter as a main component, and is mainly used to provide uninterrupted power to a single computer, a computer network system or other information equipment. The commonly used UPS is online, i.e. the load is always supplied with the required power through the inverter, and zero switching time can be achieved in ac power failure.
The online UPS is divided into a modular UPS and a tower type UPS, the modular UPS can be provided with a plurality of power modules, the redundancy is realized, and when one power module fails and the load power does not exceed the total capacity of the rest modules, the normal power supply of the equipment cannot be influenced. The tower UPS does not have redundancy, and when the UPS inverter fails and stops running, the line is switched to a bypass commercial power supply mode, and the power protection is lost. Therefore, the UPS operated by a single machine is suitable to be a modular UPS, and the tower type UPS is suitable to be used in parallel.
UPSs should have automatic (static bypass) and manual (service bypass) bypass devices. The maintenance bypass device is a common alternating current breaker generally and can bypass all components inside the UPS host to supply power for loads.
The direct current distribution equipment comprises three types: the first type is a direct current double-bus distribution panel which connects two sets of communication power supplies in parallel at the input end through a diode, and is called an input side switching direct current double-bus distribution panel for short. And the second type is a direct-current double-bus distribution panel which connects two sets of communication power supplies in parallel at the load side through a diode, namely an output side switching direct-current double-bus distribution panel for short. The third type is a direct-current double-bus distribution panel with a bus coupler switch.
