摘　　要：结合厂房变电所接地工程案例,分析出现火灾报警问题的原因,并对由此引发的接地问题进行探讨,建议变电所的设计采用TN-C-S系统,设计、制造、施工、运维等环节应重视电缆色标的正确使用。Based on the case of grounding engineering at the plant substation,the reason for fire alarm is analyzed and the resulting grounding problems are discussed. TN-C-S grounding type is recommended for the design of substation,and attention shall be paid to the proper use of color code for cable during the process of design, manufacturing,construction and O&M.
