直流不间断供电系统的割接实例分析

通信电源是通信设备的动力之源。随着电信事业的不断发展，通信设备对电源各方面的要求也越来越高。原有的通信电源因时间的推移，其容量、技术指标已不能满足通信设备的需求而需要更换。由于在线通信设备工作特性，即必须带电更换通信电源。为此，文中从割接方案制定原则、设备选型、施工场地布置、施工时间选择、注意事项及方案拟制作了一一阐述。

Analysis on the Example of Shearing and Connecting the DC UPS

Communication power supply is the the development of telecom, the requirments power source of communication equipment. With of communication equipment for every aspect of power supply are higher and higher. With the time passing, the capacity and specification of communication power supply are various with the new demand. Due to the operation characteristics of online communication equipment, the communication power supply has to be replaced. Therefore, this paper expounds the principle of the shearing and connecting scheme, equipment mode selection, construction field disposal, construction schedule choosing, attentive proceeding and scheme draft.
