产品说明：三相四线加强型电源防雷器带防爆模块
• 设备类型： 电源防雷器
最大工作电压： 385V
• 最大放电电流： 100kA
残压： 30) of the Zinc Oxide pressure-sensitive reSIStor. This makes the lightning overvoltage impact even in high energy, also can realize the maximum protection. The level of protection in the 100KA/10As under the impact, the residual pressure of not more than 2kV. Therefore, the lightning protection device can bear PARt of lightning current from direct lightning strikes. When an overload situation, lightning protection device inside, lightning protection module will automatically failure from the main circuit breaking apart, at the same time module for monitoring the working state display window colors from green to red.
二、V25-B防雷器特殊配置
Two, V25-B lightning protection device specific configuration
AS 声光报警模块 附带声音与灯光报警的功能底座，给该底座供一220V单相市电，在正常的情况下灯光显示为绿等，当有模块损坏时，报由绿色变成闪烁的红灯，并伴有“嘀嘀”报警声，提醒维护人员更换。
AS sound light alarm with sound and light alarm base module, give the base for a single-phase 220V power, in the case of normal light is green, when the module is damaged, report from green into a flashing red light, accompanied by the "beep" sound the alarm, to remind the maintenance personnel to replace.
FS遥信触点模块附带遥信触点功能底座,可根据实际需要选用端子1-2（常开触点）或1-3（常闭触点）连接。而端子接线可使用0.14-2.5mm2多股线或单芯线。
FS remote contact module with remote contact base, can be selected according to the actual needs of the terminal 1-2 (normally open) or 1-3 (normally closed contact). The terminal can use 0.14-2.5mm2 strands or single core cable.
AS 声光报警模块 、FS遥信触点模块 可使维护人员实时对防雷器工作状态进行监视。当发现防雷器不能正常工作时，维护人员只需对已失效的防雷器模块进行更换，这样可降低维护费用，更换时并不需停电。
AS alarm module, FS communication module can make real-time contact maintenance personnel of state work lightning arrester monitor. When the lightning protection device is not working properly, maintenance personnel only need to lightning protection module has faiLED to change, so can reduce the maintenance cost, replacement without interruption.
