根据《民用建筑电气设计规范》(JGJ16-2008),并参考国际IEC相关标准的要求,现代化机房有大量的一级或二级负荷,且一级负荷中还有一些特别重要的负荷。因此,在市政能够提供两路独立的10kV电源的情况下,通常采用两路10kV供电,另外自备柴油发电机作为第三电源,对于现代化机房的部分负荷、消防中心、监控中心等场所应采用UPS保证不间断供电。IEC标准对机房的不间断供电、防电击、防电气火灾等电气安全措施提出了更高的要求。1供电可靠性与电源不间断问题根据《电子信息系统机房设计规范》(GB 50174-2008)第8.1.7规定:电子信息设备应由不间断电源系
According to “Code for Electrical Design of Civil Buildings” (JGJ16-2008) and with reference to the requirements of international IEC standards, there are a large number of first-class or second-class loads in modern machine rooms and some particularly important loads in first-class loads. Therefore, when the municipal government can provide two independent 10kV power supplies, two 10kV power supplies are usually used. In addition, the self-provided diesel generator is used as the third power supply. For the partial load of a modern computer room, fire protection centers and monitoring centers should be used UPS guarantees uninterrupted power supply. IEC standards on the room uninterrupted power supply, anti-shock, anti-electrical fire and other electrical safety measures put forward higher requirements. A power supply reliability and uninterrupted power supply According to “Electronic Information System Design Specification” (GB 50174-2008) 8.1.7 states: electronic information equipment should be uninterrupted power supply system
