建筑电气设计几点思考

Considerations on Electrical Design of Buildings

针对TN系统中性线断线时出现的问题,提出采用带中性线断线保护功能的断路器来提高供电安全性;阐述雷电浪涌保护器联网远传型系统在工程应用的必要性;分析中性线配置后备保护器的原因和必要性;提出临街一层住宅壁挂式分体空调回路需要配置剩余电流动作保护器。

In view of the problems of neutral wire breakage in TN system,in this paper,a circuit breaker with neutral wire breakage protection function is suggested to improve the safety of power supply;the necessity of application of networked remote system of lightning surge protector in engineering is expounded;the reason and necessity of equipping backup protector for neutral lines are analyzed;residual current operated circuit breaker to be equipped for circuit of wall-mounted separate air conditioner for first-floor residence along streets are suggested.
