摘要
简述TN系统断路器用作故障保护的原理,并分析19DX101-1《建筑电气常用数据》中关于断路器用作故障保护时的最大允许线路长度,以及与24DX002-1《建筑电气与智能化通用规范》图示二者数据存在差异的原因,提出参考方法,便于工程设计合理应用国家建筑标准设计图集。
The principle of circuit breaker used as fault protection in TN system is described,and the reasons for the difference between the maximum allowable line length of circuit breaker used as fault protection in the national standard design Atlas 19DX101-1“Common Data of Building Electrical”and the data of 24DX002-1“General Specifications of Building Electrical and Intelligent”are analyzed.A reference method is proposed to facilitate the rational application of national design standard atlas in engineering design.
