若住宅楼仅在楼总进线和户内插座回路设置两级漏电保护装置,其所带设备和线路的泄漏电流即使属于正常范围也会使楼总开关频繁误动作跳闸,对居民生活产生较大的影响。针对此问题本文对比了不同学者所提方法的优缺点,提出了一种将住宅漏电保护装置分三级设置的方法,并将此方法在保利中央花园项目中进行了实际的应用。 If the residential building only in the building and the indoor outlet loop circuit leakage protection device set two, which brought the equipment and line leakage current even within the normal range will make the main switch frequently trip malfunction, resulting in more residents life Big impact In view of this problem, this paper compares the advantages and disadvantages of the methods proposed by different scholars, and proposes a method to set residential leakage protection devices in three stages. The method is applied in Poly Central Garden Project.
