OBO V25-B high power lightning protection device contains a special pressure sensitive resistance circuit, the circuit with nonlinear characteristics of good performance (> 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 聲光報警模塊 附帶聲音與燈光報警的功能底座,給該底座供一220V單相市電,在正常的情況下燈光顯示為綠等,當有模塊損壞時,報由綠色變成閃爍的紅燈,并伴有“嘀嘀”報警聲,提醒維護人員更換。
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 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 聲光報警模塊 、FS遙信觸點模塊 可使維護人員實時對防雷器工作狀態進行監視。當發現防雷器不能正常工作時,維護人員只需對已失效的防雷器模塊進行更換,這樣可降低維護費用,更換時并不需停電。
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.
