太阳能热水器安装更主要的就是要防雷击,尤其是夏天多雨天气下安装太阳能热水器,安装在屋顶平台的太阳能热水器,设计要求按一定规则安装,支架在屋面做防水层前将地脚螺栓植入屋面中,方法是用冲击电钻在混凝土上钻514mm的孔,再注入专用胶,将地脚螺栓植入即可。
Installation of solar water heater is the most important is to prevent lightning strikes, especially summer rainy weather installed solar water heater, install solar water heaters in the roof platform, design requirements according to certain rules of the installation, the bracket on the roof to do waterproof layer will anchor bolts into the roof, the method is with electric drills impact on concrete drill 514mm hole, and injected special glue, anchor bolt implant can be.
对于安装在坡屋顶的太阳能热水器,设计要求在屋顶的混凝土浇注好之后,同上做法做好预埋件。将安装太阳能热水器的位置预留出来,其他位置按常规铺上琉璃瓦,并在琉璃瓦下敷设两根525mm的排水管,以便将太阳能热水器处的雨水引出来。
For the installation of solar water heaters in the slope of the roof, the design requirements in the roof of concrete pouring, ibid practice to do embedded parts. The installation of solar water heater position is set aside, the other place by the conventional shop glazed tile, and in the glazed tile laying two 525mm drainage pipe, in order to the solar water heater in the rain.
太阳能热水器一般没有采用可靠的接地措施,工程实际中电加热装置的220V电源线须从每户分户箱开关后引至屋面,电源线敷设在管道井内,不仅线路复杂且在实际操作中极少对管道井内做等电位连接,易发生漏电和短路事故,漏电电流通过管道等金属体进入潮湿的卫生间,对人的生命安全构成威胁,短路起火也很容易上下贯通整个单元。
Solar water heaters generally do not have the reliable grounding measures, the 220V power line of the electric heating device in practical engineering must be from each household household switch box after the introduction to the roof, power line to be laid in the pipeline well not only and complex circuit in practice rarely to the pipeline well do etc. electric connection, prone to leakage and short circuit accident, leakage current through the metal pipe, etc. into the wet bathroom, on people's life security pose a threat, the short-circuit fire are easily through the whole unit.
况且安装避雷针(带),做好引下线和接地装置只能防直击雷,还应考虑感应雷击。感应雷电流极有可能沿水管、电源导线、信号线进入室内和室内电源系统,轻者破坏室内电气设备,重者造成人身伤亡事故。但人们对这种隐性雷电灾害认识还不够。太阳能热水器电加热管很容易爆裂,造成漏电事故不说,在屋顶更换维修也不便。
And the installation of a lightning rod (band), good wire and a grounding device can prevent lightning, lightning induction should also be considered. Lightning induced flow is very likely to enter the indoor and indoor power supply system along the water pipeline and power supply wires, signal lines, the light damage indoor electrical equipment, caused severe casualties. But it is not enough for people to understand this kind of hidden lightning disaster. The electric heating tube of the solar water heater is easy to burst, and the leakage accident is not said, and the maintenance and replacement of the roof is inconvenient.
