低压电气工程保护接地导体的设计施工

Design and Construction of Protective Earthing Conductors for LV Electrical Works

为解决GB50303-2015《建筑电气工程施工质量验收规范》和GB51348-2019《民用建筑电气设计标准》实施以来产生的设计与施工之间的问题,结合笔者30多年来的施工实践经验,提出沿桥架支架敷设镀锌扁钢是解决接地保护的最佳路径。并就此提出“沿桥架支架敷设镀锌扁钢作为保护接地体”便可使复杂且笼统的接地问题在设计与施工之间变得具体和可实迎刃而解之观点。

In order to solve the problems oceurring in design and construction since the implementation of the Code for Acceptance of Construction Qualisy of Building Electrical Enginering(GB 50303-2015)and the Standard for Electrical Design of Cwvil Buildings(CB 51348-2019),this paper presents that galvanized flat steel laying along the cable tray is the best way for earthing protection according to the author's construction experience for more than 30 years.Meanwhile,it presents an idea that galvanized flat steel laying along the cable tray as a protective earth electrode can make complex and general earthing problems concrete and easily solved in design and construction.
