摘要
针对大型建筑照明设计中存在末端线路供电距离过远的问题,结合最新相关规范要求,从电压降和短路灵敏性两个角度出发,分析集中负荷和均匀负荷两种情况下普通照明和消防应急照明线路的极限供电距离。通过工程实例分析,提出提高线路极限供电距离的改进措施。
In view of the problem that the power supply distance of the terminal line is too far in the lighting design of large-scale buildings,in combination with the requirements of the latest relevant specifications, the limit power supply distance of general lighting and fire emergency lighting lines under concentrated load and uniform load is analyzed from the perspectives of voltage drop and short-circuit sensitivity. Through the analysis of engineering examples,the improvement measures to improve the limit power supply distance of the line are put forward.
