三角避雷塔厂家价格如何?

三角避雷塔厂家价格如何?避雷塔可以作为楼顶装饰塔使用,通常来说避雷塔根据所用材料不同又可分为圆钢避雷塔和角钢避雷塔,根据功能不同又可分为避雷针塔避雷线塔两种,圆钢避雷塔因其造价低应用比较广泛.避雷塔材料可采用圆钢、角钢、钢管、单根钢管等.本公司生产的避雷塔包括:避雷针塔,避雷装饰塔,消雷塔等。

三角避雷(lei)塔厂家价(jia)格(ge)如何(he)?

避雷塔如(ru)何(he)作为通(tong)(tong)(tong)信(xin)塔来(lai)(lai)说是(shi)(shi)否会对(dui)人健(jian)康产生影(ying)响,电(dian)磁(ci)(ci)辐(fu)射(she)(she)(she)(she)源(yuan)的来(lai)(lai)源(yuan)通(tong)(tong)(tong)常(chang)有(you)以下几种:雷达系(xi)统、电(dian)视和广播发(fa)射(she)(she)(she)(she)系(xi)统、射(she)(she)(she)(she)频感应及(ji)(ji)介质加热(re)设(she)备、射(she)(she)(she)(she)频及(ji)(ji)微波(bo)医疗设(she)备、各种电(dian)加工设(she)备、移(yi)动(dong)(dong)通(tong)(tong)(tong)信(xin)基(ji)站、卫星地(di)球通(tong)(tong)(tong)信(xin)站、大型电(dian)力(li)发(fa)电(dian)站、输变电(dian)设(she)备、高压(ya)及(ji)(ji)超高压(ya)输电(dian)线、地(di)铁(tie)列车(che)及(ji)(ji)电(dian)气火车(che)以及(ji)(ji)大多(duo)数(shu)家用电(dian)器等。对(dui)于(yu)移(yi)动(dong)(dong)通(tong)(tong)(tong)信(xin)通(tong)(tong)(tong)过天线发(fa)出电(dian)磁(ci)(ci)波(bo),对(dui)于(yu)电(dian)磁(ci)(ci)波(bo)的辐(fu)射(she)(she)(she)(she)是(shi)(shi)指能量以电(dian)磁(ci)(ci)波(bo)的形式由辐(fu)射(she)(she)(she)(she)源(yuan)(天线)发(fa)射(she)(she)(she)(she)到(dao)空间的现象,简称(cheng)电(dian)磁(ci)(ci)辐(fu)射(she)(she)(she)(she)。

当(dang)(dang)电(dian)(dian)(dian)磁(ci)辐(fu)射(she)(she)穿过(guo)人(ren)体(ti)(ti)(ti)时,其能量会(hui)被人(ren)体(ti)(ti)(ti)吸收,如果这(zhei)种(zhong)能量过(guo)大,将(jiang)(jiang)会(hui)对人(ren)体(ti)(ti)(ti)健康构成危害,人(ren)体(ti)(ti)(ti)暴露在(zai)这(zhei)样的电(dian)(dian)(dian)磁(ci)辐(fu)射(she)(she)环(huan)境(jing)中(zhong),会(hui)产生(sheng)一定(ding)的影响。目前,电(dian)(dian)(dian)磁(ci)辐(fu)射(she)(she)源(yuan)的来源(yuan)通(tong)常有以下几(ji)种(zhong):雷(lei)(lei)达系统、电(dian)(dian)(dian)视和广播(bo)发(fa)射(she)(she)系统、射(she)(she)频感应及介质加(jia)热设备、射(she)(she)频及微波医疗设备、各种(zhong)电(dian)(dian)(dian)加(jia)工设备、移动(dong)通(tong)信(xin)基站、卫(wei)星地球通(tong)信(xin)站、大型电(dian)(dian)(dian)力发(fa)电(dian)(dian)(dian)站、输变电(dian)(dian)(dian)设备、高(gao)压及超高(gao)压输电(dian)(dian)(dian)线、地铁(tie)列车及电(dian)(dian)(dian)气火车以及大多数(shu)家用(yong)电(dian)(dian)(dian)器(qi)(qi)等。加(jia)装避(bi)雷(lei)(lei)器(qi)(qi)以后(hou),当(dang)(dang)输电(dian)(dian)(dian)线路遭(zao)受(shou)雷(lei)(lei)击时,雷(lei)(lei)电(dian)(dian)(dian)流(liu)的分(fen)流(liu)将(jiang)(jiang)发(fa)生(sheng)变化,一部(bu)(bu)分(fen)雷(lei)(lei)电(dian)(dian)(dian)流(liu)从避(bi)雷(lei)(lei)线传入相临(lin)杆塔,一部(bu)(bu)分(fen)经塔体(ti)(ti)(ti)入地,当(dang)(dang)雷(lei)(lei)电(dian)(dian)(dian)流(liu)超过(guo)一定(ding)值后(hou),避(bi)雷(lei)(lei)器(qi)(qi)动(dong)作加(jia)入分(fen)流(liu)。大部(bu)(bu)分(fen)的雷(lei)(lei)电(dian)(dian)(dian)流(liu)从避(bi)雷(lei)(lei)器(qi)(qi)流(liu)入导线,传播(bo)到相临(lin)杆塔。雷(lei)(lei)电(dian)(dian)(dian)流(liu)在(zai)流(liu)经避(bi)雷(lei)(lei)线和导线时,由于导线间的电(dian)(dian)(dian)磁(ci)感应作用(yong),将(jiang)(jiang)分(fen)别在(zai)导线和避(bi)雷(lei)(lei)线上产生(sheng)耦合分(fen)量。

因(yin)为避雷(lei)器(qi)的(de)(de)分流(liu)远远大于(yu)从(cong)避雷(lei)线(xian)(xian)(xian)中分流(liu)的(de)(de)雷(lei)电(dian)(dian)(dian)流(liu),这种分流(liu)的(de)(de)耦(ou)合作(zuo)用(yong)将(jiang)使(shi)导线(xian)(xian)(xian)电(dian)(dian)(dian)位(wei)提高,使(shi)导线(xian)(xian)(xian)和(he)塔顶之间的(de)(de)电(dian)(dian)(dian)位(wei)差(cha)小于(yu)绝缘子串(chuan)的(de)(de)闪络(luo)电(dian)(dian)(dian)压,绝缘子不会发生闪络(luo),因(yin)此,线(xian)(xian)(xian)路(lu)避雷(lei)器(qi)具(ju)有很好的(de)(de)钳电(dian)(dian)(dian)位(wei)作(zuo)用(yong),这也是线(xian)(xian)(xian)路(lu)避雷(lei)器(qi)进(jin)行防雷(lei)的(de)(de)明显(xian)特点。以往(wang)输(shu)电(dian)(dian)(dian)线(xian)(xian)(xian)路(lu)防雷(lei)主要(yao)采(cai)用(yong)降(jiang)(jiang)低塔体接地(di)电(dian)(dian)(dian)阻(zu)的(de)(de)方(fang)法,在(zai)平(ping)原地(di)带相对(dui)较(jiao)容易,对(dui)于(yu)山区(qu)杆塔,则往(wang)往(wang)在(zai)4个塔脚部(bu)位(wei)采(cai)用(yong)较(jiao)长的(de)(de)辐射地(di)线(xian)(xian)(xian)或打深井加降(jiang)(jiang)阻(zu)剂,以增加地(di)线(xian)(xian)(xian)与土壤的(de)(de)接触面积降(jiang)(jiang)低电(dian)(dian)(dian)阻(zu)率,在(zai)工频状(zhuang)态下接地(di)电(dian)(dian)(dian)阻(zu)会有所(suo)下降(jiang)(jiang)。

三角(jiao)避(bi)雷(lei)(lei)塔(ta)(ta)厂家价格(ge)(ge)如(ru)何?但(dan)遭(zao)受雷(lei)(lei)击时,因(yin)接地(di)线(xian)(xian)过(guo)长(zhang)会(hui)有较大(da)的(de)附加(jia)电(dian)(dian)感值,雷(lei)(lei)电(dian)(dian)过(guo)电(dian)(dian)压的(de)暂态分量L.di/dt会(hui)加(jia)在塔(ta)(ta)体电(dian)(dian)位(wei)上,使(shi)塔(ta)(ta)顶电(dian)(dian)位(wei)大(da)大(da)提高,更容(rong)易(yi)造成塔(ta)(ta)体与(yu)绝缘子串的(de)闪(shan)络,反(fan)而使(shi)线(xian)(xian)路(lu)(lu)的(de)耐雷(lei)(lei)水(shui)平下(xia)降。因(yin)为(wei)线(xian)(xian)路(lu)(lu)避(bi)雷(lei)(lei)器具有钳电(dian)(dian)位(wei)作用,对接地(di)电(dian)(dian)阻(zu)要求不太严格(ge)(ge),对山区(qu)线(xian)(xian)路(lu)(lu)防雷(lei)(lei)比较容(rong)易(yi)实现(xian)。
