在建筑工程电气设计中,常遇到一些值得注意或引起争论的问题,对于某些问题笔者对照有关设计规范,谈谈自己的看法及分析,仅供电气设计人员参考。一供配电系统设计:1.解析负荷分级《供配电系统设计规范》GB50052-2009第3.0.1条电力负荷根据对供电可靠性的要求及中断供电在对人身安全、经济损失上所造成的影响程度分为三级。其中在一级负荷中,当中断供电将造成人员伤亡或重大设备损坏或发生中毒、爆炸和火灾等情况的负荷,以及特别重要场所的不允许中断供电的负荷,应视为一级负荷中特别重要负荷。
In the architectural design of electrical engineering, often encountered some worth noting or controversial issues, for some problems I control the design specifications, to talk about their own views and analysis, for reference only for electrical designers. A power distribution system design: 1. Analytical load classification “Design specifications for power distribution systems” GB50052-2009 Section 3.0.1 Power load According to the reliability of power supply and interrupt power supply in the personal safety, economic losses caused The degree of influence is divided into three levels. Among them, in the first-class load, the load caused by interrupting the power supply which will cause casualties or major equipment damage or poisoning, explosion and fire, etc., and the non-interrupting power supply in particularly important places shall be regarded as the first-class load Important load.
