消防负荷分组设计做法分析

Analysis of Fire Load Grouping Design Practice

变压器低压侧母线一般按照不分组设计,接线简单且造价低,但是目前出现了分组设计方案,将消防负荷、非消防负荷从变压器低压侧开始分为两段母线供电,形成各自独立的系统,这种方案已在规范中推广并被设计人员采用在工程实例中。通过对消防符合分组设计方案进行分析,提出一些个人看法,以供同行参考。

Transformer low voltage side bus according to the grouping design, general wiring simple and low cost, but the grouping design at present, the fire load and fire load from the low voltage side of transformer can be divided into two bus power supply, the for- mation of independent system, this scheme has been popularized in the specification and to be used in engineering design personnel, this article to talk about their own views ,Through analyzed the metdod of fierload grouping design,some views are put forward for designers reference.
