摘要
讨论高大型电动游乐设备的防雷和接地措施,高度大于15m的应装设避雷带,防雷接地电阻小于10Ω,低压配电型式采用TN—S系统。采取等电位接地及应用电涌保护器也是主要的技术措施。介绍国际和国内的有关规范,并结合工程实际提出具体做法。
measurements for Earthing and lightning protection high electrical amusements rides are discussed. Rides more than 15m should set lightning protection bar. Earthing resistence should be less than 10 Ohms. Low-voltage power distribution earthing type adopt TN-S system. Equipotential earthing and using SPD are also important measurements. Relevant international and domestic code are introduced, and detail practice example is given.
