建筑电气是现代建筑的重要元素,安全用电是使用者应修的课程,以人为本的理念将用电安全推向更高的平台。九十年代起,住宅建筑的电气设计,采用T N-C-S供电系统的接地方式,在户开关箱内设置漏电保护断路器(以下简称漏保器),控制户内全部电源插座(空调插座例外)。当漏电流≥30m A, Building electrical is an important element of modern architecture, safe use of electricity users should repair the curriculum, people-oriented concept of electricity safety to a higher platform. Since the nineties, the electrical design of residential buildings, using T N-C-S power supply system grounding mode, set in the switch box leakage protection circuit breaker (hereinafter referred to as leakage protector), control all indoor power outlet (air conditioning outlet exceptions). When the leakage current ≥ 30m A,
