2p/3p直流DC浪涌IMAX40KA
光伏介绍
太阳能电涌保护器正常情况下保护器处于高阻状态,当电网或其它原因出现浪涌过电压时,保护器将立即在纳秒级时间内迅速导通,将浪涌过电压引入大地,从而保护电网的用电设备。如汇流箱、裂变器、直流屏等。保护器模块上设置有失效脱离装置,当保护器因过热、击穿失败时,失效脱离器能自动地将其从电网上脱离,同时给出指示信号。保护器正常工作时,指示器显示绿色,脱离失效后显示红色,表明电涌保护器需跟换。光伏专用防雷器LM1-D1000/40/2p3p电源防雷器的通流容量是二级电源防雷保护器。根据防雷原理,雷电能量经一次释放后,在电源线上仍有较高的残压,应通过防雷系统前、后级防雷器配合,使雷电能量逐级释放,才能有效地保护终端用电设备,直流屏、汇流箱、裂变器等。
Surge protection device of solar protection device is in the high impedance state, when the surge was observed in the grid or other reasons, protector will immediately in the nanosecond time rapidly conducting, surge into the earth, so as to protect the power grid of electrical equipment. Such as bus, fission device, DC screen, etc.. The protection module is arranged on the failure from the device, when the protection from overheating, breakdown failure, failure can be automatically disengaging from its power from the grid, and gives the indication signal. The protection of the normal working time, the green indicator shows, from the failure of red, that SpD need to change. Special lightning protector LM1-D1000/40/2p3p photovoltaic power arrester current capacity is two level power supply lightning protection device. According to the principle of lightning protection, lightning energy after a release, residual pressure is still higher in the power supply line should be through the lightning protection system, after lightning arrester, lightning energy gradually release to effectively protect the terminal electrical equipment, DC screen, junction box, fission and other.

安装与应用
流电源防雷器的安装接线最好采用凯文接线法,也可以采用直接并联接线。并联接线时,接线总长度宜控制在0.5米以内,并要短而平直,以尽量缩短雷电流路径;
在电源防雷器的引接线上,应串接保护熔断器(或空开),防止防雷器故障时引起系统供电系统的故障。熔断器(或空开)的标称电流不应大于前级供电线路熔断器或空开的1/1.6倍;
