目前,太阳能热水器(以下简称热水器)多为铁皮、铝合金等电的良导体材料制成,一般都在建筑物施工完毕后安装。建筑物的防雷系统中未考虑热水器的防雷,而现今的热水器体积越来越大,安装高度也越来越高,有的高度甚至超过了建筑物顶上的烟囱、女儿墙等易受雷击部位的高度,这样热水器便成了最易受雷击的部位。 At present, solar water heaters (hereinafter referred to as water heaters) are mostly made of good conductive materials such as iron sheets and aluminum alloys, which are generally installed after the construction of buildings is completed. The lightning protection of the water heater is not considered in the lightning protection system of the building, but the size of the current water heater is larger and larger, the installation height is also getting higher and higher, and some of the heights even surpass the chimney and parapet walls on the top of the building. The height of the lightning strike is such that the water heater is the most vulnerable to lightning strikes.
