產(chǎn)  品  名  稱：加強型三相四線防雷器

Product  Name: strengthen type three-phase four line lightning arrester

一、V25-B防雷器功能

A， V25-B lightning protection function

OBO V25-B高能量防雷器內(nèi)含一個特別的壓敏電阻電路，該電路由具備性能良好的非線性特性（> 30）的氧化鋅壓敏電阻組成。這使得該防雷器即使在高能量的過電壓沖擊下，也能夠最大限度地實現(xiàn)保護。其保護水平為在100KA/10As沖擊下，殘壓不超過2kV。因此，該防雷器能夠承受來自于直接雷擊下的部分雷電流。當(dāng)線路過載情況發(fā)生時，防雷器內(nèi)部的斷路器，會自動將失效的防雷器模塊從主電路分斷開來，同時模塊上用于監(jiān)視工作狀態(tài)的顯示窗口的顏色會由綠色轉(zhuǎn)變?yōu)榧t色。

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(dāng)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遙信觸點模塊附帶遙信觸點功能底座，可根據(jù)實際需要選用端子1-2（常開觸點）或1-3（常閉觸點）連接。而端子接線可使用0.14-2.5mm2多股線或單芯線。

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(tài)進行監(jiān)視。當(dāng)發(fā)現(xiàn)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.
