3，避(bi)雷器(qi)安(an)裝要求(qiu)說明(ming)：

1、SPD應用(yong)于(yu)主分配電(dian)(dian)(dian)系(xi)統為220V或(huo)380V第一(yi)、二、三級雷電(dian)(dian)(dian)防護，并聯安裝(zhuang)在建筑(zhu)物配電(dian)(dian)(dian)箱或(huo)機房的電(dian)(dian)(dian)源(yuan)進線端，配35mm電(dian)(dian)(dian)氣導軌，可采(cai)用(yong)凱文(wen)連(lian)接(jie)方式。安裝(zhuang)前必須切(qie)斷電(dian)(dian)(dian)源(yuan)，嚴禁帶電(dian)(dian)(dian)操作。

2、安(an)裝(zhuang)時(shi)請(qing)根據安(an)裝(zhuang)示(shi)意圖(tu)所示(shi)連接，其(qi)中L為相線(xian)，N為零線(xian)，PE為地線(xian)，切勿(wu)錯接。安(an)裝(zhuang)完成后，合(he)上(shang)自動斷(duan)路器開關，檢查工作(zuo)狀態是否正(zheng)常。

3、在AC供配電系(xi)統中(zhong)，為防止SPD老化短路造(zao)成系(xi)統故障，SPD安(an)裝(zhuang)線路上應(ying)有過(guo)電流(liu)保護器(qi)件，并選(xuan)用(yong)有劣化顯示功能的SPD；

4、避雷(lei)器應盡量安(an)裝在(zai)被保護(hu)設(she)(she)備內(nei)，若無法(fa)安(an)裝在(zai)被保護(hu)設(she)(she)備內(nei)時，必須(xu)先將SPD安(an)裝在(zai)安(an)裝盒內(nei)，再安(an)裝在(zai)附近的墻上或靠(kao)近被保護(hu)設(she)(she)備的其它地方；

5、SPD連(lian)接導線長(chang)度不宜超過(guo)0.5m，接地引線應盡量避免與電源(yuan)線緊挨平行(xing)布設(she)，并宜粗、短(duan)、直；

6、當SPD1至SPD2的線距(ju)長度(du)小于(yu)10米時(shi)， SPD2至SPD3的線距(ju)長度(du)小于(yu)5米時(shi)，需(xu)要(yao)在SPD之間應(ying)加裝退耦電感；

7、各級電(dian)源(yuan)SPD必須(xu)安裝在交(jiao)流配電(dian)設備的交(jiao)流輸入(ru)端，宜采用凱文接線方式連(lian)接（將室內接地(di)(di)(di)匯集線與(yu)接地(di)(di)(di)引(yin)入(ru)線連(lian)接處斷開(kai)，斷開(kai)處的兩端分(fen)別單獨引(yin)線接至(zhi)SPD的接地(di)(di)(di)端）；

8、80KA三相電(dian)源(yuan)(yuan)防雷箱和空氣開關(guan)與35mm的(de)標(biao)準導(dao)軌(gui)可靠(kao)固定，電(dian)源(yuan)(yuan)一級SPD連(lian)接(jie)導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)經不(bu)得小(xiao)于(yu)16mm2,接(jie)地導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)徑不(bu)得小(xiao)于(yu)25mm2；電(dian)源(yuan)(yuan)二級SPD連(lian)接(jie)導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)經不(bu)得小(xiao)于(yu)10mm2,接(jie)地導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)徑不(bu)得小(xiao)于(yu)16mm2；電(dian)源(yuan)(yuan)三級SPD連(lian)接(jie)導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)經不(bu)得小(xiao)于(yu)6mm2,接(jie)地導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)徑不(bu)得小(xiao)于(yu)10mm2；信號避(bi)雷器連(lian)接(jie)導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)經不(bu)得小(xiao)于(yu)2.5mm2,接(jie)地導(dao)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)徑不(bu)得小(xiao)于(yu)6mm2；

9、電源SPD應以最短、直路徑(jing)接(jie)地，SPD的接(jie)地線應避(bi)免出現“V”形和(he)“U”形彎(wan)(wan)，連(lian)線的彎(wan)(wan)曲角度不得小(xiao)于90°，且接(jie)地線必須綁扎固(gu)定(ding)好，松緊適中；

10、SPD連接線的走(zou)線要美觀，特別是直線、轉彎、連接頭，保證SPD整潔美觀，連接牢固可靠(kao)；
