提(ti)起接(jie)(jie)(jie)地(di)(di)(di)，估計大部(bu)分(fen)電(dian)(dian)(dian)(dian)氣人員都不陌生了(le)。隨著科(ke)學技術的(de)(de)(de)(de)快速(su)發展，電(dian)(dian)(dian)(dian)氣設(she)備(bei)(bei)(bei)的(de)(de)(de)(de)應用(yong)越來越廣泛(fan)，為了(le)提(ti)高電(dian)(dian)(dian)(dian)氣設(she)備(bei)(bei)(bei)運(yun)行(xing)的(de)(de)(de)(de)可(ke)靠性，則需要(yao)將電(dian)(dian)(dian)(dian)氣裝(zhuang)(zhuang)置或(huo)(huo)電(dian)(dian)(dian)(dian)氣線路(lu)帶電(dian)(dian)(dian)(dian)部(bu)分(fen)的(de)(de)(de)(de)某(mou)點(dian)與(yu)(yu)(yu)大地(di)(di)(di)連(lian)(lian)接(jie)(jie)(jie)，電(dian)(dian)(dian)(dian)氣裝(zhuang)(zhuang)置或(huo)(huo)其它裝(zhuang)(zhuang)置正常(chang)(chang)時不帶電(dian)(dian)(dian)(dian)部(bu)分(fen)某(mou)點(dian)與(yu)(yu)(yu)大地(di)(di)(di)的(de)(de)(de)(de)人為連(lian)(lian)接(jie)(jie)(jie)都叫接(jie)(jie)(jie)地(di)(di)(di)；亦可(ke)說成電(dian)(dian)(dian)(dian)力設(she)備(bei)(bei)(bei)，桿塔或(huo)(huo)過電(dian)(dian)(dian)(dian)壓保護裝(zhuang)(zhuang)置用(yong)接(jie)(jie)(jie)地(di)(di)(di)線通過埋(mai)入(ru)地(di)(di)(di)中并直(zhi)接(jie)(jie)(jie)與(yu)(yu)(yu)大地(di)(di)(di)接(jie)(jie)(jie)觸的(de)(de)(de)(de)金屬導(dao)體與(yu)(yu)(yu)大地(di)(di)(di)連(lian)(lian)接(jie)(jie)(jie)。電(dian)(dian)(dian)(dian)力系(xi)統中接(jie)(jie)(jie)地(di)(di)(di)的(de)(de)(de)(de)部(bu)分(fen)一(yi)般是(shi)(shi)中性點(dian)，也可(ke)以是(shi)(shi)相(xiang)線上的(de)(de)(de)(de)某(mou)一(yi)點(dian)，電(dian)(dian)(dian)(dian)氣設(she)備(bei)(bei)(bei)的(de)(de)(de)(de)接(jie)(jie)(jie)地(di)(di)(di)部(bu)分(fen)則是(shi)(shi)正常(chang)(chang)情況下(xia)不帶電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)金屬導(dao)體，一(yi)般為金屬外(wai)殼。電(dian)(dian)(dian)(dian)氣設(she)備(bei)(bei)(bei)接(jie)(jie)(jie)地(di)(di)(di)是(shi)(shi)防止用(yong)電(dian)(dian)(dian)(dian)事故發生的(de)(de)(de)(de)重要(yao)措施。那(nei)么電(dian)(dian)(dian)(dian)氣設(she)備(bei)(bei)(bei)：哪(na)些是(shi)(shi)必(bi)須(xu)接(jie)(jie)(jie)地(di)(di)(di)？哪(na)些是(shi)(shi)不需要(yao)接(jie)(jie)(jie)地(di)(di)(di)呢？下(xia)面我(wo)們一(yi)起來看看吧！

為了(le)保證維護人員的安全，發電廠、變電站內的電氣設(she)備是必須要接地。

1.電(dian)機、變壓器(qi)(qi)、電(dian)器(qi)(qi)、照明器(qi)(qi)具、攜帶(dai)式(shi)及移動式(shi)用電(dian)器(qi)(qi)具等的底座和外(wai)殼。

2.電(dian)氣設(she)備的操控機(ji)構(gou)。

3.儀用互感器的二次繞組。

4.配(pei)電箱(xiang)、控制箱(xiang)的(de)框架。
