我国有关建筑电气规范不少引用了建筑电气国际标准IEC60364的规定。但多摘录了条文规定,缺乏条文说明,在应用中不明白规定的制定意图,影响了规范的正确执行。《建筑物电气装置600问》作者从事IEC60364标准归口工作逾30年,作了大量的调查研究。《建筑物电气装置600问》以问答方式结合一些案例深入浅出地阐述国际标准条文制定的依据。对低压电气装置的接地、等电位联结、电气分隔、雷电和操作过电压防护、暂时过电压防护、过电流和电...
我国有关建筑电气规范不少引用了建筑电气国际标准IEC60364的规定。但多摘录了条文规定,缺乏条文说明,在应用中不明白规定的制定意图,影响了规范的正确执行。《建筑物电气装置600问》作者从事IEC60364标准归口工作逾30年,作了大量的调查研究。《建筑物电气装置600问》以问答方式结合一些案例深入浅出地阐述国际标准条文制定的依据。对低压电气装置的接地、等电位联结、电气分隔、雷电和操作过电压防护、暂时过电压防护、过电流和电气火灾防护、“断零”防护、抗电磁干扰以及特殊场所的提高要求等国际标准制定的缘由等都进行了介绍。
《建筑物电气装置600问》可供建筑电气的设计、安装、检验、监理、维护、规范编制人员以及建筑电气专业师生参考使用。

前言 第1章 接地 1.1 何谓接地? 1.2 飞机上的电气装置如何接地? 1.3 何谓接地故障? 1.4 配电系统的接地如何设置? 1.5 在问答1.4 中电源的中性点为何又名之为星形结点? 1.6 系统接地的作用是什么? 1.7 保护接地的作用是什么? 1.8 10/0.4 kV变电所的接地是系统接地还是保护接地? 1.9 在变电所(发电机站)内如何实施系统接地? 1.10 请举例说明上一问答中杂散电流产生杂散电磁场引起的电磁干扰 1.11 如果两台变压器不在一个变电所内,如何为防止杂散电流干扰信息系统电气装置而实施电源PEN线的一点接地? 1.12 一般变电所的变压器中性点套管出线为何不是中性线而是PEN线? 1.13 从变压器引出的既然是PEN线,那么是否只能从变电所引出TN-C-S系统和TN-C系统,不能引出TN-S系统和TT系统? 1.14 变电所系统接地的接地电阻值按我国接地规范规定为不大于4Ω或不大于10Ω。这一接地电阻值能否满足系统接地的安全性和功能性要求?
1.15 配电系统对保护接地的设置有何要求? 1.16 我国在给一排靠墙布置的设备以TN-C系统配电时,将三根相线架空走线,而PEN线则用不绝缘的扁钢沿墙脚明敷。这一做法妥否? 1.17 我国原采用的接零系统、接地系统、不接地系统、零线等术语为什么被废止不用而改用TN-C、TN-S、TN-C-STTIT等接地系统和中性线、PE线、PEN线等术语?
