無(wu)功功率（無(wu)功電流）型(xing)的(de)控(kong)制器(qi)較完善(shan)的(de)解決了功率因數型(xing)的(de)缺陷。一個設(she)計良(liang)好的(de)無(wu)功型(xing)控(kong)制器(qi)是智能(neng)(neng)化的(de)，有很強(qiang)的(de)適應能(neng)(neng)力，能(neng)(neng)兼顧線路的(de)穩定性(xing)及(ji)檢測及(ji)補(bu)償效果(guo)，并(bing)能(neng)(neng)對補(bu)償裝置進行完善(shan)的(de)保護及(ji)檢測，這類控(kong)制器(qi)一般都具(ju)有以(yi)下功能(neng)(neng)：

安裝低(di)壓補償(chang)模(mo)組在光伏(fu)產業中(zhong)的作用

放電(dian)(dian)(dian)(dian)(dian)時先將接(jie)(jie)地線(xian)接(jie)(jie)地端接(jie)(jie)好，再用(yong)接(jie)(jie)地棒(bang)多(duo)(duo)次對電(dian)(dian)(dian)(dian)(dian)容器放電(dian)(dian)(dian)(dian)(dian)，直(zhi)至(zhi)無放電(dian)(dian)(dian)(dian)(dian)火花及放電(dian)(dian)(dian)(dian)(dian)聲為(wei)止，然后(hou)將接(jie)(jie)地端固定(ding)好。由于故(gu)(gu)障電(dian)(dian)(dian)(dian)(dian)容器可能發生引線(xian)接(jie)(jie)觸不(bu)良、內(nei)部斷(duan)線(xian)或(huo)熔絲(si)熔斷(duan)等(deng)，因此有部分電(dian)(dian)(dian)(dian)(dian)荷(he)可能未(wei)放盡(jin)，所以(yi)檢(jian)修人員在接(jie)(jie)觸故(gu)(gu)障電(dian)(dian)(dian)(dian)(dian)容器之前，還應(ying)戴上(shang)(shang)絕(jue)緣手套，先用(yong)短路線(xian)將故(gu)(gu)障電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)容器兩極短接(jie)(jie)，然后(hou)方動(dong)手拆卸和更換。 對于雙(shuang)星形接(jie)(jie)線(xian)的電(dian)(dian)(dian)(dian)(dian)容器組的中性線(xian)上(shang)(shang)，以(yi)及多(duo)(duo)個(ge)電(dian)(dian)(dian)(dian)(dian)容器的串接(jie)(jie)線(xian)上(shang)(shang)，還應(ying)單獨(du)進行放電(dian)(dian)(dian)(dian)(dian)。

可替(ti)代(dai)常規由熔絲、復合開關或機械式接(jie)觸器(qi)、熱繼電(dian)器(qi)、低(di)壓電(dian)力電(dian)容器(qi)、指示燈等(deng)散件在柜內和柜面由導線連(lian)接(jie)而組成的自動無(wu)(wu)功補償(chang)裝置。改變了(le)傳統無(wu)(wu)功補償(chang)裝置體積龐(pang)大和笨重的結構模式，具有補償(chang)效果(guo)更(geng)好，體積更(geng)小，功耗更(geng)低(di)，價格更(geng)廉，節(jie)約成本更(geng)多，使(shi)用更(geng)加靈活，維護更(geng)方便，使(shi)用壽命(ming)更(geng)長，可靠性更(geng)高的特(te)點(dian)，適應了(le)現代(dai)電(dian)網對無(wu)(wu)功補償(chang)的更(geng)高要(yao)求。
