電(dian)(dian)(dian)源(yuan)浪(lang)(lang)涌(yong)(yong)(yong)保護器(qi)是用(yong)來保護電(dian)(dian)(dian)源(yuan)線路(lu)及(ji)設備的瞬態沖擊(ji)浪(lang)(lang)涌(yong)(yong)(yong)。主要分為一(yi)級(ji)電(dian)(dian)(dian)源(yuan)浪(lang)(lang)涌(yong)(yong)(yong)保護器(qi)、二級(ji)電(dian)(dian)(dian)源(yuan)浪(lang)(lang)涌(yong)(yong)(yong)保護器(qi)、三級(ji)電(dian)(dian)(dian)源(yuan)浪(lang)(lang)涌(yong)(yong)(yong)保護器(qi)和四級(ji)電(dian)(dian)(dian)源(yuan)浪(lang)(lang)涌(yong)(yong)(yong)保護器(qi)等四個(ge)級(ji)別(bie)。

那么在建筑(zhu)物的電源雷電防護(hu)中，該如何進行選型適配呢(ni)？鈞(jun)和(he)電子給您(nin)詳細分析：

一、確定(ding)(ding)配電系統(tong)中設備的耐沖(chong)擊電壓(ya)額(e)定(ding)(ding)值

二、浪涌保護器的最大持續工作電壓U_C不應低于表中的規定值

三、電(dian)源浪涌保護器的具體選型適(shi)配方(fang)法

1.進入建筑物的交流供電線路，在線路的總配電箱等LPZ0_A或LPZ0_B與LPZ1區交界處，應設置I類(lei)(lei)試(shi)(shi)(shi)驗(yan)的(de)(de)(de)浪(lang)(lang)涌(yong)(yong)保(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)或(huo)II類(lei)(lei)試(shi)(shi)(shi)驗(yan)的(de)(de)(de)浪(lang)(lang)涌(yong)(yong)保(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)作(zuo)(zuo)為(wei)(wei)第一級保(bao)(bao)護(hu)(hu)(hu)(hu)；在(zai)配(pei)電(dian)(dian)(dian)(dian)(dian)線路分配(pei)電(dian)(dian)(dian)(dian)(dian)箱、電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)備機房配(pei)電(dian)(dian)(dian)(dian)(dian)箱等后續防護(hu)(hu)(hu)(hu)區交(jiao)界處(chu)，可(ke)設(she)置(zhi)II類(lei)(lei)或(huo)III類(lei)(lei)試(shi)(shi)(shi)驗(yan)的(de)(de)(de)浪(lang)(lang)涌(yong)(yong)保(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)作(zuo)(zuo)為(wei)(wei)后級保(bao)(bao)護(hu)(hu)(hu)(hu)；特(te)殊(shu)重要(yao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)信息設(she)備電(dian)(dian)(dian)(dian)(dian)源端口可(ke)安(an)裝II類(lei)(lei)或(huo)III類(lei)(lei)試(shi)(shi)(shi)驗(yan)的(de)(de)(de)浪(lang)(lang)涌(yong)(yong)保(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)作(zuo)(zuo)為(wei)(wei)精(jing)細保(bao)(bao)護(hu)(hu)(hu)(hu)。使(shi)用直流(liu)電(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)信息設(she)備，視(shi)其工(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)壓要(yao)求，宜安(an)裝適(shi)配(pei)的(de)(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)源線路浪(lang)(lang)涌(yong)(yong)保(bao)(bao)護(hu)(hu)(hu)(hu)器(qi)。

2.浪涌保護器設置級數應綜合考慮保護距離、浪涌保護器連接導線長度、被保護設備耐沖擊電壓額定值U_W等因素。各級浪涌保護器應能承受在安裝點上預計的放電電流，其有效保護水平UP/F應小于相應類別設備的U_W

3.當電(dian)壓(ya)開關(guan)型浪(lang)涌(yong)保(bao)(bao)護器(qi)至(zhi)限壓(ya)型浪(lang)涌(yong)保(bao)(bao)護器(qi)之間的線(xian)路(lu)長度(du)小于10米、限壓(ya)型浪(lang)涌(yong)保(bao)(bao)護器(qi)之間的線(xian)路(lu)長度(du)效率5米時(shi)，在兩級浪(lang)涌(yong)保(bao)(bao)護器(qi)之間應加裝(zhuang)退耦裝(zhuang)置。當浪(lang)涌(yong)保(bao)(bao)護器(qi)具有能(neng)量自動(dong)配合功能(neng)時(shi)，浪(lang)涌(yong)保(bao)(bao)護器(qi)之間的線(xian)路(lu)長度(du)不受限制。浪(lang)涌(yong)保(bao)(bao)護器(qi)應有過(guo)電(dian)流(liu)保(bao)(bao)護裝(zhuang)置和(he)劣化(hua)顯示功能(neng)。

4.根據雷(lei)電防(fang)護(hu)等(deng)級(ji)，用(yong)于電源線路(lu)的浪涌保護(hu)器(qi)的沖擊電流(liu)和標稱放電電流(liu)參數如下：

5.電源浪涌(yong)保護(hu)器在各個位置安(an)裝時，浪涌(yong)保護(hu)器的連(lian)接導線(xian)應(ying)短直，其(qi)總(zong)長度不宜大宇0.5米。有效保護(hu)水(shui)平應(ying)小于(yu)設(she)備耐沖擊(ji)電壓額定值。

6.電源線路浪(lang)涌保(bao)護(hu)(hu)器安裝位置(zhi)與被保(bao)護(hu)(hu)設備之間的線路長(chang)度(du)大宇(yu)10米。

7.入戶處(chu)第(di)一級電源(yuan)浪(lang)涌保護(hu)器(qi)與(yu)被保護(hu)設(she)備(bei)(bei)間的(de)線(xian)路長度大于規定(ding)值時，應(ying)在(zai)(zai)配電線(xian)路的(de)分配電箱處(chu)或(huo)在(zai)(zai)被保護(hu)設(she)備(bei)(bei)處(chu)增設(she)浪(lang)涌保護(hu)器(qi)。當一條線(xian)路上設(she)置多級浪(lang)涌保護(hu)器(qi)時應(ying)考慮他(ta)們之間的(de)能(neng)量(liang)協調(diao)配合。

四、注意事項

1.室外進、出(chu)電子信(xin)息系統機房的電源線路不宜采(cai)用架空線路。

    2.電子信息系(xi)統(tong)設備由(you)TN交流配(pei)電系(xi)統(tong)供電時，從建筑物(wu)內總(zong)配(pei)電柜（箱(xiang)）開始(shi)引(yin)出的配(pei)電線路必須采(cai)用TN-S系(xi)統(tong)的接地(di)形式。
