摘　　要：直流输电方式比较交流输电方式有明显的优越性,历史上仅仅由于技术的原因,才使得交流输电代替了直流输电。近年来,我国在特高压直流输电领域已走在了世界前列,直接直流供电方式也在逐步推广应用,很多数据中心导入了直流供电,获得了显著的经济效益。以直流方式进行家庭供电,对用户也很有利。本文对家居直流供电的必要性及其标准化进行了探讨,阐述了直流供电的特点和优势,并展望了建筑直流供电技术的发展前景。DC transmission mode has obvious advantages in comparison to AC transmission mode, which, only due to technical rea-sons, makes AC transmission instead of DC transmission. In recent years, China has been in the forefront of the world in the field ofhigh voltage direct current transmission, and direct current power supply is also gradually spread, many data centers into the DC powersupply, and access to significant economic benefits. It is also very favorable to the users in the form of direct power supply. In this pa-per, the necessity and the standardization of the DC power supply to ordinary residence are discussed, the characteristics and advantag-es of the DC power supply are described, and the development prospects of the building DC power supply technology are outlooked.
