我国建筑电气的接地概念有待更新

摘要

就我国和发达国家在建筑电气的接地中存在的差距，以新版IEC接地标准为依据，对接地中有待更新的概念，诸如何谓接地、接地中的防电化学腐蚀和选材走线要求、优选的接地方式、接地和抗电磁干扰的关系以及接地电阻值的规定等问题进行陈述。%In view of differences in earthing in the building electrical design between China and the developed countries, relevant concepts to be updated conerning earthing, such as the definition of earthing, requirements for protection against electro-chemical corrosion, material selection and routing, preferred earthing mode, relationship between earthing and anti-electromagnetic interference and provisions on earthing resistance, are presented in accordance with the latest IEC earthing standards.
