太阳能热水器雷电防护技术分析

Analysis of Lightning Protection Technology of the Solar Water Heater

太阳能热水器的雷电防护隐患很大,每年都有不少雷击案例发生。通过调查发现,大多数热水器无雷电防护装置;多安装在屋顶,易招致雷击;安装人员多为非专业人员,缺乏必备的雷电防护知识。对太阳能热水器造成危害的不仅有直击雷,还有感应雷。因此,太阳能热水器的雷电防护,既要采取防直击雷防护措施,也要采取防雷电感应措施。

Because of the lightning protection of solar water heaters existing lots of potential prob-lems,lightning accidents happen every year. According to the research,on the one hand,most of the so-lar water heaters installed on the roof do not have the lightning protective devices,so it is easier to be struck by lightning. On the other hand,the installation persons are almost non-professionals,who are lacking of lightning protection knowledge. Both direct lightning flesh and induction lightning cause the damage of solar water heater,so the protection of solar water heater should prevent both of them.
