箱(xiang)變分為設(she)備(bei)接(jie)地和外(wai)殼接(jie)地,請問,我設(she)備(bei)接(jie)地是否(fou)一定要單獨(du)打一個接(jie)地極引到地下(xia),然后設(she)備(bei)接(jie)地銅(tong)牌與此獨(du)立接(jie)地極連起來?不(bu)做可以嗎?
在沒有特殊要求情況(kuang)下,沿高壓開關柜的(de)(de)寬(kuan)度(du)方向設TMY-25X3的(de)(de)銅排作為專(zhuan)用(yong)接地(di)母(mu)線。每個功(gong)能單元應(ying)設與該接地(di)母(mu)線連接的(de)(de)M12的(de)(de)接地(di)樁或(huo)接地(di)螺母(mu)。
用截(jie)面相當于接(jie)(jie)(jie)地(di)母(mu)(mu)線的銅排或軟導線與(yu)(yu)該接(jie)(jie)(jie)地(di)母(mu)(mu)線可靠(kao)連接(jie)(jie)(jie),或通過與(yu)(yu)接(jie)(jie)(jie)地(di)母(mu)(mu)線保(bao)(bao)持可靠(kao)電氣連接(jie)(jie)(jie)的柜體與(yu)(yu)接(jie)(jie)(jie)地(di)母(mu)(mu)線相連。該接(jie)(jie)(jie)地(di)母(mu)(mu)線未端(duan)還(huan)要設(she)有與(yu)(yu)接(jie)(jie)(jie)地(di)網相連的M12的固(gu)定連接(jie)(jie)(jie)端(duan)子,并設(she)有明顯的保(bao)(bao)護接(jie)(jie)(jie)地(di)標識。

質量要求
1、接地導體必須是銅(tong)質的(de),銅(tong)編織線的(de)長(chang)(chang)度要長(chang)(chang)短適宜,以免浪費和影響美觀;
2、銅編織線端頭(tou)必須按(an)相關(guan)技術要求壓接規(gui)格相當(dang)的銅線鼻子,需要搪錫的按(an)搪錫要求處(chu)理,線鼻子孔徑(jing)大小與螺栓大小相配;
3、接地(di)導體連接接地(di)點的表(biao)面要求清(qing)潔(jie)、無噴漆層、噴塑層、無油污;
4、使用接(jie)(jie)地墊圈,墊圈能將(jiang)元(yuan)件(jian)和框架接(jie)(jie)地點的(de)表面涂層劃開,保(bao)證(zheng)接(jie)(jie)觸良好(hao);
5、接地軟連接要(yao)可靠固定,并與主回路之間始終保證(zheng)足夠的安全距離;
6、接地(di)連接螺(luo)栓(螺(luo)釘)要求(qiu)連接緊固可(ke)靠;
7、產(chan)品外殼的接(jie)(jie)地(di)連接(jie)(jie)點處,應粘貼醒(xing)目的保護(hu)接(jie)(jie)地(di)符號。
