应急电源与备用电源的设计

摘要

供电电源是电气系统中最为关键、重要的环节之一。很多工程中,除正常电源外,根据具体情况和用电需求,还需设置应急电源和备用电源。分析了应急电源和备用电源的概念和内涵,并结合规范和实际工程,探讨了应急电源和备用电源的供电范围、设置要求、电源类型以及系统构建形式。%The power supply is one of the most critical and important part of the electrical system. In many pro- jects, in addition to the normal power supply, depending on the specific circumstances and the demand for electricity, emergency power and stand-by power also need to be set up. The definition and concept of emergency supp]y and stand- by supply were analyzed. Combining with design standard and practical engineering project, the scope of supply, the e- mergency power supply and stand-by power supply, set requirements, the type of power supply, and system form of e- mergency supply and stand-by supply were expounded.
