在一般多层住宅的防雷设计中,对于防雷接地和电气设备接的方式以及两者之间的关系,看法不一,做法也不同。目前较普通的有下面三种做法:1.防雷与电气设备分别单独设人工接地装置;2.防雷接地利用建筑物的基础钢筋,电气设备单独设置人工接地;3.防雷与电气设备共用接地装置。本文想从人身安全、设备安全、耗料、用工等方面对三种做法谈点看法,进行一些比较。 In the lightning protection design of general multi-storey residential buildings, there are different views and different approaches for the lightning protection grounding, the connection of electrical equipment, and the relationship between the two. At present, the following three methods are more common: 1. Artificial grounding devices are separately provided for lightning protection and electrical equipment; 2. Grounding reinforcement of the building is used to make use of the basic reinforcement of the building, and artificial electrical grounding is separately provided for electrical equipment; 3. Lightning protection and electrical equipment Common grounding device. This article wants to talk about the three approaches from the perspectives of personal safety, equipment safety, material consumption, employment, etc., and make some comparisons.
